Description

[Technical field]

[0001] The present invention relates to textile products made of knitted fabrics, and more particularly to textile products such as socks, leg warmers, and arm warmers that are thick and have excellent heat retention, and in particular to those having a pile knit structure. [Background technology]

[0002] Traditionally, textile products knitted in a bag-like shape such as socks or gloves, and textile products knitted in a tubular shape such as leg warmers and arm warmers have been widely used to protect against the cold when working or playing sports in low-temperature environments, but in recent years, products that are thicker than ever before and have excellent heat retention, while at the same time being lightweight and comfortable to wear, have been manufactured and distributed. Furthermore, the uses of textile products with excellent heat retention continue to expand, such as extremely thick socks that can be used as so-called indoor shoes (room slippers). In recent years, with the growing awareness of energy conservation, indoor heating temperatures are often set low, and it is expected that such textile products will be used more and more in the future.

[0003] A representative example of a knitted fabric that is thick and has excellent heat retention is a pile knitted fabric. A pile knitted fabric is made by knitting loops in a ring shape on the surface of the knitted fabric, covering the surface or both sides of the knitted fabric with pile, so that it is very flexible and comfortable to wear regardless of its thickness. In addition, the pile contains a lot of air, so it has excellent heat retention and is an excellent feature as a textile product for cold weather. In a pile knitted fabric, the pile can be made thicker by making the loops longer, and more air can be contained therein, thereby further improving heat retention.

[0004] However, textile products such as socks, leg warmers, and arm warmers are often worn directly on the skin, and therefore are often washed frequently. When this happens, in a knitted structure with long loops, i.e., thick pile, the pile will flatten or collapse and become clogged, resulting in a thin thickness. Naturally, the air contained in the pile will decrease, and the heat retention will also decrease. Even for applications that do not require frequent washing, textile products with long-loop pile knitted structures tend to have similar inconveniences due to the packaging and transportation stages and friction during use. In particular, in socks, the pile is likely to flatten or collapse due to the weight being applied and being exposed to strong friction, so it is important to improve the stability and recovery of the pile knitted structure.

[0005] In response to this problem, Japanese Patent Application Laid-Open No. 5-247797 and Japanese Patent Application Laid-Open No. 2017-106146 disclose a double pile knitting structure in which the loops constituting the pile are doubled, consisting of a large loop with a high height and a small loop with a low height. In this structure, a small loop is formed inside the large loop that appears on the outermost side of the knitting structure, and this supports the large loop, so that the problem of the pile becoming flat or crushed even after repeated washing is greatly reduced, even though the pile knitting structure is thick and has a long pile length.

[0006] However, in the inventions described in the prior art documents, it is difficult to improve the heat retention by forming a thicker pile. This is because, even in a configuration in which a small loop is provided inside a large loop, if the loop is made longer, that is, if each of the large and small loops becomes large, the pile is likely to flatten or be crushed even in a double pile knitted structure. In addition, it is technically possible to further increase the number of loops constituting the pile to form a triple loop structure of large loops, medium loops, and small loops to strengthen the pile, but in this case, the basis weight (density) of the knitted fabric layer of the knitted fabric (the knitted fabric layer knitted by so-called flat knitting or rib knitting with the main yarn and reinforcing yarn) becomes too high, making the knitted fabric as a whole stiff and inferior in wearing comfort.

[0007] Another problem is that when a thick pile is constructed, the large loops constituting the outermost layer are bent, and the small loops inside are visible through the gaps between the large loops. In double pile knitting, the yarns constituting the large loops in the outermost layer are often selected with emphasis on texture and design, such as cotton yarns that are soft to the touch and wool yarns that provide a beautiful luster. On the other hand, the yarns constituting the small loops in the inner layer, which do not come into contact with the human body and are not visible, are often selected with emphasis on functions such as strength, such as elasticity, that can maintain the pile structure, and insulation. In this case, when the large loops constituting the outermost layer are bent and the small loops inside are exposed through the gaps between the large loops, the yarns constituting the small loops, which are inferior in design, are visible to the wearer, which is very inconvenient for clothing. Of course, if the small loops made of yarns selected with priority on the above-mentioned functions come into direct contact with the skin, it will also cause a decrease in wearing comfort.

[0008] [Patent Document 1] Japanese Patent Application Publication No. 5-247797 [Patent Document 2] JP 2017-106146 A Summary of the Invention [Problem to be solved by the invention]

[0009] The problem to be solved by the present invention is to provide a textile product that overcomes the above-mentioned drawbacks, i.e., that ensures the stability of the pile layer, which was difficult to achieve with the conventional double pile knitting structure, that can withstand long-term use even with a thicker pile knitting structure, and that maintains excellent comfort and design by covering the small loops constituting the inner layer with the large loops constituting the outermost layer. [Means for solving the problem]

[0010] (1) In order to solve the above-described problems, the present invention provides At least a part of the thickened portion is provided, The thick part is composed of a knitted layer and a pile layer formed of a main yarn and a reinforcing yarn, The pile layer comprises a first pile formed by a first pile yarn and a second pile formed by two or more second pile yarns, The second pile is configured inside the first pile. The textile product is characterized by the above.

[0011] An important feature of the textile product according to the present invention is that it has a thickness that provides sufficient heat retention, but it is not necessary for the entire textile product to have a uniform thickness. For example, when the textile product is a sock, the sole part may be made thick to insulate the sole from the cold floor, while the instep part may not require much thickness. Therefore, the textile product according to the present invention is characterized by having at least a part of the thick part. However, when the textile product is a leg warmer or arm warmer, etc., and it is preferable in terms of the function and usability of the product to make the entire textile product a thick part, it is also possible to make the entire textile product a thick part.

[0012] The thick part is composed of a knitted layer knitted by so-called flat knitting or rib knitting with the main yarn and the reinforcing yarn, and a pile layer knitted together with the main yarn and the reinforcing yarn to create a ring-shaped loop on the surface of the knitted layer. The main yarn is knitted to cover the surface of the knitted layer and determines the design such as color and luster of the knitted layer and the wearing feeling such as touch. The reinforcing yarn is knitted together with the main yarn and stabilizes the knitted structure by its strength and elasticity. Such a knitted layer made of the main yarn and the reinforcing yarn is a general knitted layer of a pile knitted structure. In the present invention, the pile layer is composed of a first pile made of a first pile yarn and a second pile made of two or more second pile yarns, and the second pile is provided inside the first pile, so to speak, a double pile structure.

[0013] If a single pile is made long, the pile will flatten or collapse and become packed together as the textile product is used or washed, resulting in a thinner thickness and reduced heat retention. On the other hand, the thick section of the present invention has a second pile thread of shorter length made of two or more second pile yarns provided inside a first pile thread of longer length, which provides support so that the pile threads do not easily flatten or collapse, maintaining a sufficient thickness and, naturally, heat retention for a long period of time.

[0014] Even if the second pile is made of only one second pile yarn, it can retain the first pile to some extent and improve stability. However, if a higher pile layer is formed to form a thicker pile knitting structure with excellent heat retention, the second pile made of only one second pile yarn will not have enough retention. In principle, the retention should be increased if the second pile yarn is made of a thick and strong yarn, but this will make the pile layer as a whole stiff and lacking in flexibility, significantly impairing the wearing comfort of the textile product.

[0015] On the other hand, when the second pile is made of two or more second pile yarns, a softer and more flexible knitted structure is obtained compared to when the second pile is made of one second pile yarn with the same total cross-sectional area, and at the same time, the two or more second pile yarns spread out to support the first pile as a three-dimensional structure rather than a line, so that the knitted structure obtained is stable in that the first pile is strongly supported despite its softness. Furthermore, the fact that the two or more second pile yarns spread out to form the second pile as a three-dimensional structure also has the effect of further improving the heat retention of the thick part of the textile product according to the present invention. In particular, when a highly elastic yarn is used for the second pile yarn, the two or more second pile yarns knitted while being stretched randomly change direction when they shrink, forming a three-dimensional structure like futon cotton, which contains air and provides better heat retention than would be expected from a pile knitted structure that is simply thick.

[0016] Incidentally, the number of the second pile yarns is preferably in the range of 2 to 4. If the number of the second pile yarns is too large, the density (weight per unit area) of the knitted structure becomes too large, and the knitted structure becomes hard and dense, impairing the wearing comfort. Specifically, it is not preferable to have 5 or more second pile yarns. Also, in textile products used in particularly harsh conditions (typically, such as socks, which are exposed to the load of body weight and strong friction), the number of the second pile yarns is preferably 2. This is because each second pile yarn has a certain thickness, and as a result, it is necessary for the second pile layer to have good supporting force. On the other hand, in textile products that are not used in very harsh conditions, the number of the second pile yarns is preferably 3, and the reason for this is the balance between the necessary supporting force and the obtained wearing comfort.

[0017] As already explained, if the number of second pile yarns is increased too much or if a third pile layer is provided, the density of the knitted fabric becomes too high, making it hard and dense, which impairs the feel of use. However, according to the research of the present inventor, it has been found that if the density of the knitted fabric is increased too much, the heat retention property is also reduced. Although this research result is somewhat counterintuitive, the heat retention (magnitude of thermal resistance) of the knitted fabric is greatly affected by the amount of air contained in the knitted fabric. If the number of second pile yarns is increased too much or a third pile layer is provided, the amount of air contained in the pile layer as a whole is reduced, which is considered to result in a decrease in the heat retention property of the knitted fabric. In other words, the number of second pile yarns and the number of pile layers are not necessarily the more the better, but there are suitable values. According to the research of the present inventor, it has been shown that in the case of typical textile products related to clothing including socks, the preferable number of second pile yarns is 2 to 4, and the number of pile layers is 2.

[0018] In the present invention, since the second pile is hidden inside the first pile, the second pile is made of yarn that emphasizes functionality, the first pile is made of yarn that emphasizes comfort, and the main yarn of the knitted layer is made of yarn that emphasizes design and durability, so that a textile product can be made that makes the most of the advantages of each yarn. In particular, the second pile made of two or more second pile yarns stably holds the first pile that is visible from the outside, so that the highly designed and beautiful appearance made of the first pile can be maintained for a long period of time. Similarly, it is also a great advantage that the second pile, which has excellent heat retention and recovery, rarely comes into contact with the wearer's skin, so that the good wearing comfort of the first pile can be dominated.

[0019] For example, in the case of socks, the pile layer is usually configured to come into contact with the wearer's skin, but in this case, the main yarn of the knitted layer is the outermost layer and is the part that is visible from the outside when the textile product is worn, so it is configured with beautiful and strong yarns of materials such as wool and polyester, the second pile is configured with two yarns of polypropylene material that is particularly excellent in heat retention, and the first pile can be configured with cotton-based yarn that is comfortable to wear. In this example, an excellent textile product is realized that utilizes the advantages of polypropylene yarn, which is light and has excellent heat retention (almost no water retention and low thermal conductivity), while preventing the manifestation of its disadvantages due to its slippery nature and almost no moisture absorption. In other words, because of the knitted layer, the polypropylene yarn is hardly exposed to the outside, so slipperiness is not an issue. In addition, because it is covered by the first pile, there is no problem of sweat accumulating and causing discomfort due to its lack of moisture absorption. Thus, one of the great advantages of the present invention is that it is possible to provide a textile product which not only has sufficient thickness and excellent heat retention, but also brings out the advantages of various characteristic yarns and has a pile knitting structure which is stable over a long period of time.

[0020] It goes without saying that the types of yarn constituting the knitted fabric layer, the type of the first pile yarn, and the type of the second pile yarn are not limited to the above examples, and various types can be used depending on the purpose.

[0021] As already explained, the textile product according to the present invention is characterized in that the thick part has a pile layer made of a first pile yarn and a second pile yarn, and the second pile is arranged inside the first pile. As a method for realizing such a characteristic structure, knitting can be performed by a knitting machine equipped with a special pile sinker, i.e., a pile sinker having a recessed portion on which the knitting yarn, the second pile yarn, and the first pile yarn can be hung at different depths. Alternatively, the second pile yarn may be knitted by applying tension as an elastic yarn such as an elastic polyurethane material, so that when the knitting structure is completed, the loops become smaller due to the contraction of the second pile yarn, and the second pile is arranged inside the first pile. Furthermore, the second pile yarn may be made shrinkable by heat treatment or alkaline washing treatment to obtain a similar finished shape.

[0022] (2) In order to solve the above-described problems, the present invention provides The second pile yarn is a covering yarn in which a core yarn having a thickness of 10 to 30 denier is wrapped with a sheath yarn having a thickness of 170 to 210 dtex. The textile product is characterized by the above (1).

[0023] As already explained, in the present invention, the second pile is formed by two or more second pile yarns, so that the first pile layer is well supported and the warmth and design are maintained for a long time even if a higher pile layer is formed. However, if the second pile yarn is too thin, the supporting force is insufficient, and if it is too thick, the knitted structure becomes too dense, so that it is hard and lacks flexibility, and the wearing comfort is impaired. In the research of the present inventor, it was found that in typical textile products related to clothing including socks, the pile layer is stabilized and a good result is obtained in terms of wearing comfort by using the second pile yarn as a covering yarn in which a sheath yarn equivalent to a thickness of 170 decitex to 210 decitex is wrapped around a core yarn of a thickness of 10 denier to 30 denier. Therefore, in the present invention, a second pile yarn having a thickness in this range is used. The meaning of "equivalent to a thickness of 170 decitex to 210 decitex" in the characteristic "equivalent to a thickness of 170 decitex to 210 decitex" will be described later.

[0024] In addition, it is preferable that the core yarn of the second pile yarn has a thickness of 10 to 20 denier. By forming the second pile with two or more second pile yarns, a relatively stable pile layer can be obtained even with a thinner second pile yarn, while a softer and more flexible knitted structure can be obtained, improving the wearing comfort. Furthermore, it is more preferable that the core yarn of the second pile yarn has a thickness of 10 denier. This is because an even softer and more flexible knitted structure can be obtained, improving the wearing comfort. It is very difficult to strictly determine the thickness of the yarn due to the uncertainty of the cross-sectional shape and manufacturing variations, and therefore a fixed length unit such as denier is used as a guideline for the thickness. Although there is a strong correlation between the guideline unit for the thickness of the yarn and the strength, restoring force, etc., there is not a perfect correspondence relationship. Therefore, in the present invention, it is intended that the thickness of the yarn be defined with the accuracy of the level displayed in general commercial transactions. For example, a thickness of 10 denier is within the permissible range of error of 10% to 20%, that is, a thickness of about 12 denier is assumed to be within the technical scope of the present invention.

[0025] Incidentally, since the strength of the covering yarn (thread stiffness) is dominated by the influence of the core yarn, various choices of sheath yarns are possible depending on the purpose of the textile product and the convenience of manufacturing. In the case of a covering yarn using one sheath yarn, the sheath yarn can be selected from the range of 170 decitex to 210 decitex. Alternatively, a covering yarn using two sheath yarns in the range of 85 decitex to 105 decitex can be used. Similarly, a covering yarn using three sheath yarns in the range of 63 decitex to 70 decitex can be used. In short, as long as the total thickness of the sheath yarn (in this case, the unit is decitex, so it is actually the mass of the yarn per a certain length) is in the range of 170 decitex to 210 decitex, it can be used as the second pile yarn of the textile product according to the present invention, and the reason why the characteristic of the present invention is described as "equivalent to a thickness of 170 decitex to 210 decitex" is to express that the total thickness of the sheath yarns is in this range. However, using too many thin sheath yarns can be inconvenient as it can easily cause accidents during production, so it is preferable to use a covering yarn using one to three sheath yarns.

[0026] (3) In order to solve the above-described problems, the present invention provides The first pile yarn has a thickness of 2 / 24 to 2 / 32. The textile product is characterized by the above-mentioned in (2).

[0027] In the present invention, the first pile layer constitutes the outer side of the pile layer of the knitted fabric, and is therefore visible from the outside and comes into contact with the skin when the textile product is worn. Therefore, it is preferable that the first pile layer has excellent design such as color and luster suitable for use as a textile product, and excellent wearing comfort such as texture. In addition, since the first pile layer is exposed to strong friction with the skin, etc., if it does not have sufficient strength, it will wear out or break in a short period of time.

[0028] Therefore, it is preferable to use a yarn having a thickness of 2 / 24 to 2 / 32 as the first pile yarn. If the first pile yarn is too thin, the first pile will easily bend even when supported by the second pile, resulting in the second pile, which is inferior in design and comfort, being exposed, and the strength will be insufficient and easily worn. On the other hand, if the first pile yarn is too thick, it will tend to give an impression of roughness in appearance, such as a lack of fineness, and will lose smoothness against the skin, reducing comfort.

[0029] Also, it is preferable that the first pile yarn has a thickness of 2 / 26 to 2 / 30. In textile products such as socks, which are loaded by body weight and exposed to strong friction, there is not much technical room for selection of the constituent yarns of the first pile layer in order to simultaneously achieve strength, design, and wearing comfort, and it is preferable to specifically set it within the above range. According to the research of the present inventor, it has been found that the best results are obtained by setting the thickness of the first pile yarn to 2 / 28, but since it is difficult to define and guarantee the thickness of the yarn with high precision, it is preferable to set it as above in practice.

[0030] In the present invention, the first pile yarn is basically one strand, but it may be two or more strands. In the case of the second pile, the number of second pile yarns is preferably selected within the range of two to four strands, and outside this range, different problems arise depending on whether the number is more or less, which is complicated. On the other hand, in the case of the first pile, the parties involved may set the number of first pile yarns as necessary depending on the purpose, such as when a denser surface is required.

[0031] (4) In order to solve the above-described problems, the present invention provides: The second pile yarn is a covering yarn in which either a polypropylene resin fiber yarn or a nylon resin fiber yarn is wrapped around a polyurethane elastic fiber yarn. The textile product is characterized by the above (3).

[0032] As already explained, the second pile of the present invention supports the first pile, which is long and thick, and prevents the pile from becoming flat or crushed even when the textile product is repeatedly washed or rubbed. For this reason, the pile yarn constituting the second pile must have a certain strength and elasticity. In addition, since the second pile is covered by the first pile, it is hardly visible on the surface, so that the effect on the design of the knitted structure and the wearing feeling such as the touch is limited. For this reason, it is desirable to select yarns that emphasize functional properties such as heat retention and light weight, and realize a knitted structure with better functions. Therefore, in the present invention, the second pile yarn is preferably composed of a covering yarn with a polyurethane elastic fiber yarn as a core yarn and a polypropylene resin fiber yarn or a nylon resin fiber yarn as a sheath yarn.

[0033] In the present invention, one of the important features is that the second pile is formed inside the first pile. One of the means for realizing this is a method in which the second pile yarn forming the second pile is an elastic yarn, and this yarn and the first pile yarn are fed into a knitting machine together and tensioned to knit the pile. When the knitting structure is completed, the stretched second pile yarn shrinks to its original length due to its elasticity, and as a result, the loops forming the second pile become smaller, realizing the configuration of the present invention. As such an elastic yarn, it is preferable to use a covering yarn in which a polyurethane elastic fiber having high elasticity is used as a core wire and a yarn of a type according to the purpose is wound around it. In this case, the core wire shrinks after being knitted as a pile due to its elasticity, and plays a role of forming the second pile that fits inside the first pile. The wound yarn is made of a yarn having functions such as heat insulation and moisture absorption and heat generation, and becomes a second pile that exhibits these functions. In this way, it becomes possible to freely form the second pile even with functional fibers with low elasticity. In a specific example, it is highly preferable to use a covering yarn having a polyurethane elastic fiber yarn as a core wire and a polypropylene resin fiber yarn wrapped around it as the second pile yarn, since this can achieve both the elasticity required to realize the dimensions and shape of the second pile and the low thermal conductivity required to realize excellent heat retention.

[0034] In addition, polypropylene resin has a characteristic of low thermal conductivity, so polypropylene resin fibers are a preferred choice for the present invention, which aims to improve heat retention. In particular, hollow fibers made of polypropylene material have very low thermal conductivity and almost no water absorption, so they are extremely preferred for their high heat retention. On the other hand, as a textile product worn on the body, they have the disadvantages of being too slippery and causing discomfort due to sweat accumulation. However, if the second pile, which is wrapped by the first pile and does not directly touch the body, is made of this material, an excellent textile product can be obtained in which these disadvantages are not apparent.

[0035] The knitted structure according to the present invention can also be constructed by using a yarn that shrinks when heat-treated as the second pile yarn, and shrinking the second pile yarn by heat-treating the knitted structure after knitting the knitted structure. In general, fibers made of highly crystalline resins often have heat-shrinkage properties, and there are many polypropylene resin fibers, polyurethane resin fibers, and nylon resin fibers on the market that have such heat-shrinkage properties, and yarns made of such fibers can also be used in the present invention.

[0036] In this way, it is possible to manufacture the textile product according to the present invention without making major modifications to knitting machines that have been used conventionally, which has the advantage that it is possible to provide the textile product according to the present invention at a lower cost through reduced capital investment, etc.

[0037] Incidentally, the above example shows a covering yarn wrapped with a hollow fiber made of polyurethane material, but it goes without saying that the present invention is not limited to this, and that the person concerned can select a different fiber according to the purpose. For example, moisture-absorbing heat-generating fibers, which have a large surface area of ​​hydrophilic fibers and thus generate a strong sense of heat due to the heat of hydration (heat of aggregation) when moisture is absorbed, are widely used, but these fibers are generally very thin in order to obtain a large surface area, and in most cases, their strength and durability are inferior to those of ordinary fibers. However, if such a moisture-absorbing heat-generating fiber is included in at least a part of the second pile yarn according to the present invention, the moisture-absorbing heat-generating fiber is wrapped in the first pile yarn, and is not exposed to friction with the outside, so there is no problem with strength or durability. Specifically, a covering yarn in which a fiber having moisture-absorbing heat-generating properties is wrapped around a core wire of a polyurethane elastic fiber yarn is used as the second pile yarn to realize a textile product having moisture-absorbing heat-generating properties.

[0038] Incidentally, when the second pile yarn according to the present invention is a covering yarn in which a polyurethane elastic fiber yarn is wrapped with a polypropylene resin fiber or a nylon resin fiber, there is an advantage from a viewpoint other than excellent wearing comfort such as touch. The second pile yarn may not directly touch the skin, and can be made into a relatively strong (firm) yarn. As a result of forming the second pile with such yarn, the pile layer has excellent cushioning properties. For this reason, for example, when a sock with a thick layer on the sole is made as an example of the textile product according to the present invention, not only the sole is warm when walking, but also a good cushioning property is felt. When using thick socks as indoor shoes, the cushioning property of the sole is an extremely preferable feature that absorbs shocks when walking, and this is also one of the excellent effects of the present invention.

[0039] (5) In order to solve the above-described problems, the present invention provides The first pile yarn is a blended yarn containing acrylic fibers and wool fibers. The textile product is characterized by the above (4).

[0040] In the present invention, the first pile is thick and almost completely covers the second pile and the knitted fabric layer on the inside, so that substantially only the first pile is visible on the side of the textile product according to the present invention on which the first pile is provided. Furthermore, of the yarns constituting the knitted structure of the textile product, substantially only the first pile touches the skin of the wearer. Therefore, the first pile is required to have a high design quality such as excellent color and luster, and to be pleasant to the touch. Furthermore, in the case of socks, for example, the pile layer is usually configured to touch the skin of the wearer, but in this case, the thick pile is subjected to a large load due to the body weight and is exposed to strong friction with the skin, so the first pile yarn is also required to have a certain degree of toughness.

[0041] For this reason, it is preferable that the first pile yarn is made of a blended yarn containing acrylic fiber and wool fiber. These fibers all have a beautiful luster, excellent dyeability, excellent elasticity, and wrinkle resistance, which allows for the realization of textile products with excellent design. Wool fiber also has good moisture absorption properties, allowing for the realization of textile products with excellent wearing comfort. In addition, functional fibers that have been given moisture absorption and heat generation properties are available on the market for acrylic fibers, which are preferable because they allow the wearer to feel warmth immediately after wearing the textile product. Specifically, Ex (registered trademark), an acrylic moisture absorption and heat generation fiber manufactured by Nippon Exlan Kogyo Co., Ltd., can be used.

[0042] In addition, it is also a preferred embodiment of the present invention that the first pile yarn is made of a blended yarn containing cotton fiber and polyester fiber. Cotton fiber is very soft to the touch and has excellent moisture absorption properties, and is a material that is widely used for textile products that directly contact the skin. In the present invention, since the first pile is usually thick, a blended yarn containing polyester fiber, which has excellent elasticity and strength, can be used to make a textile product that is comfortable to wear and durable.

[0043] In order to solve the above-described problems, the present invention provides The main yarn, the reinforcing yarn, the first pile yarn, and the second pile yarn are all different yarns. The textile product is characterized by the above (5).

[0044] In the thick part of the present invention, since the main yarn and the first pile yarn constitute the surface of the knitted structure (the surface facing the outside regardless of whether it is the front or back of the textile product), it is preferable to select yarns that are excellent in design and wearing comfort, and since the reinforcing yarn and the second pile yarn constitute the internal structure of the knitted structure covered by the main yarn and the first pile yarn, it is preferable to select yarns that are excellent in heat retention and strength, as already explained. However, it goes without saying that even for the main yarn and the first pile yarn that appear on the surface of the knitted structure, the wearing comfort is more important on the side that touches the skin when the textile product is worn, and the design is more important on the side that is exposed to the outside. Similarly, for the reinforcing yarn and the second pile yarn, while the former is important for strong elasticity to maintain the structure of the entire pile knitted structure of the thick part, the latter is important for functions such as low thermal conductivity to maintain the pile layer and improve the heat retention of the thick pile layer. In short, when various functions are required from one yarn, a trade-off relationship inevitably arises between the functions, and a certain degree of compromise is unavoidable, but in the present invention, the main yarn, reinforcing yarn, first pile yarn, and second pile yarn that make up the thick part can all be made of different yarns suited to the respective required functions, thereby obtaining the most favorable results. Note that different yarns do not necessarily mean different materials, but rather mean the use of spun yarns of the same material but with different thicknesses or different fiber blend ratios.

[0045] In order to solve the above-described problems, the present invention provides In the knitted fabric layer, 90% or more of the reinforcing yarn is covered with the main yarn, In the pile layer, the second pile yarn is covered by the first pile yarn by 90% or more. The textile product is characterized by the above (5).

[0046] As described above, in the thick part of the present invention, the reinforcing yarn and the second pile yarn are selected with a priority on functions such as strength and low thermal conductivity, so that the beauty of appearance (design), moisture absorption, and pleasant feel (wearing comfort) are not necessarily the best. For this reason, the main yarn and the first pile yarn, which are excellent in design and wearing comfort, are used to cover the reinforcing yarn in the knitted layer and the second pile yarn in the pile layer. In the present invention, the reinforcing yarn and the second pile yarn are well covered by the main yarn and the first pile yarn by making each yarn the type and thickness as described above, but since the knitted structure is essentially knitted with yarns whose shape is unstable, it is extremely difficult to guarantee a 100% coverage rate in the strict sense. In the present invention, in order to obtain a design and wearing comfort sufficient for practical use, the coverage rate is at least 90% or more. In addition, the coverage rate is preferably 95% or more, more preferably 98% or more. This is because, at such a high coverage rate, little difference is felt in terms of comfort when worn, but the improvement in design is visible.

[0047] (6) In order to solve the above-described problems, the present invention provides The textile product according to any one of (1) to (5). A sock characterized by:

[0048] Socks are the most preferred example of the textile product according to the present invention, which is characterized by having a thick part that is extremely warm and has a surface that comes into contact with the skin, which is made of highly comfortable yarn. It goes without saying that a thick pile layer provides good warmth, but if the second pile yarn that constitutes the second pile layer that is formed inside the first pile layer contains polypropylene hollow yarn with high thermal resistance or moisture-absorbing heat-generating fiber, the socks will have even higher warmth. The wearing surface (i.e., the surface that comes into direct contact with the skin of the foot when the sock is worn) can be the surface on which the pile layer is provided, or conversely, the surface on which the knitted fabric layer is provided. In the former case, since the first pile layer comes into direct contact with the skin of the foot, it is preferable to use a material for the first pile yarn that is comfortable to the touch and comfortable to wear, while the knitted fabric layer is made of a material that has a beautiful appearance and is durable at the upper part. Needless to say, in the latter case, the opposite is preferable. In either case, the sufficient thickness of the pile layer that constitutes the thick part and the second pile provide extremely excellent warmth.

[0049] Furthermore, socks generally bear a large load due to the weight of the wearer, are subjected to strong friction as the wearer walks, and are washed frequently, but in the present invention, the first pile layer is supported by the second pile layer to maintain high stability, so that the pile will not flatten or become crushed even with harsh use over a long period of time, and will maintain good condition and heat retention. In this way, socks with high value from a practical standpoint are realized.

[0050] Incidentally, the socks according to the present invention can also be partially provided with thicker parts. As an example, it is possible to provide a thicker part only on the floor surface of the sole of the sock. In this way, it is possible to increase the heat retention of the surface that comes into contact with the cold floor, where much of the body heat is lost, and effectively prevent the sock from getting cold, while the other parts can be made relatively thin and not bulky, and since a small amount of yarn is required to knit the sock, it is possible to provide the sock at a low cost. However, it is possible to appropriately determine which parts of the sock the thicker parts are provided on. For example, it is possible to provide a thicker part on the part that wraps around the ankle in addition to the sole to prevent the ankle from getting cold.

[0051] (7) In order to solve the above-described problems, the present invention provides The textile product according to any one of (1) to (5). A leg warmer characterized by the above.

[0052] Leg warmers intended to keep calves, knees, thighs, etc. warm are also preferred examples of textile products according to the present invention. When shoes are worn, particularly safety shoes worn when handling heavy objects, the size variations are limited, and it may be difficult to wear shoes when wearing thick socks according to the present invention. However, even in such cases, wearing the leg warmers according to the present invention can prevent chill to a considerable extent, and similar to the socks according to the present invention, the characteristics such as durability are also preferred as leg warmers.

[0053] Leg warmers are usually textile products knitted into a relatively simple cylindrical shape, but as mentioned above, they are often worn when going out. In addition, they are often used in a state where they are clearly visible from the outside, such as when a woman wears a skirt and wears a leg warmer, so high designability is required. For this reason, when the wearing surface is the pile layer side, it is preferable that the knitted fabric layer on the outer surface is made of a material that can provide a beautiful appearance, such as wool yarn. Also, when the wearing surface is the knitted fabric layer side, it is preferable to use a yarn that can provide a beautiful appearance for the first pile that appears on the outermost layer of the pile layer on the outer surface. In the pile layer according to the present invention, the second pile is hidden inside the first pile, so that the first pile yarn and the second pile yarn do not appear mixed on the surface, and this is advantageous in that the aesthetic appearance is not impaired.

[0054] Generally, leg warmers are often used to refer to tubular textile products that cover the calves, knees, and thighs, but the leg warmers intended by this invention are intended to refer to tubular textile products that are open at both ends and are intended to keep the legs warm, and therefore the concept also includes textile products that cover only the ankles to keep warm, and textile products that cover only the knees to keep warm. These could also be called ankle warmers or knee warmers, but they are all referred to as leg warmers.

[0055] (8) In order to solve the above-described problems, the present invention provides The textile product according to any one of (1) to (5). The arm warmers feature:

[0056] Arm warmers, which are intended to keep the upper arm, elbow, and lower arm warm, are also a preferred example of the textile product of the present invention. The arm warmers of the present invention are very thick and provide good heat retention, but the knitted fabric itself is not very thick, so they are flexible and can be worn comfortably on parts of the body that move a lot, such as the arms, without interfering with movement. The selection of materials for making arm warmers is almost the same as for leg warmers.

[0057] In general, arm warmers are often used to refer to tubular textile products intended to keep the upper arm, elbow, and lower arm warm, but the arm warmers intended by this invention are intended to refer to tubular textile products with both ends open to keep the arms warm, and therefore include textile products that cover only the wrists to keep warm, and textile products that cover only the elbows to keep warm. These could also be called wrist warmers or elbow warmers, but they are all referred to as arm warmers.

[0058] (9) In order to solve the above-described problems, the present invention provides The textile product according to any one of (1) to (5). A body warming device characterized by the above.

[0059] Cylindrical textile products with a circumference of several tens of centimeters are often used as a warming device for the human trunk. Typical examples include so-called belly warmers and sleepers worn by infants when sleeping. In these applications, the characteristic of the present invention, which has a very large thickness while being flexible and having good warmth retention, is extremely preferable. In addition, when used as a sleeper for infants whose skin is delicate, if the sleeper has seams, these can cause skin disorders. However, the present invention provides a sleeper that is a knitted fabric with no seams, so such problems do not occur.

[0060] In addition, in the case of a torso warmer that is normally worn over clothing and does not come into direct contact with the skin, such as a belly warmer, the second pile yarn can also be one that prioritizes strength and durability rather than one that prioritizes comfort. On the other hand, in the case of a torso warmer that is worn over clothing but comes into direct contact with the skin of the fingers, neck, etc., such as a sleeper, it goes without saying that it is preferable to select one that prioritizes comfort when worn, such as one that is soft and smooth. Effect of the Invention

[0061] (1) The textile product has a thick part consisting of a knitted layer and a pile layer, and the pile layer is characterized by comprising a first pile made of a first pile yarn and a second pile made of a second pile yarn made of two or more pile yarns arranged inside the first pile yarn, so that it is possible to provide a textile product with a very large thickness and extremely high heat retention. In addition, since the second pile made of two or more pile yarns supports the first pile from the inside, it is possible to maintain the thickness and heat retention for a long period of time even after the textile product is used or washed. In addition, since the two or more second pile yarns form a three-dimensional structure like futon batting and contain air, it is possible to obtain a heat retention that is superior to that expected for a pile knitting structure that is simply thick.

[0062] In addition, even in the thick part, the knitted layer that determines the flexibility (ease of bending) of the textile product is thin, and thus, despite the very large thickness, a textile product that is flexible and comfortable to wear can be provided. Furthermore, since the first pile of the thick part is in direct contact with the skin, while the second pile is hardly in direct contact with the skin, the first pile yarn can be made of a material that emphasizes design such as color and luster and texture, while the second pile yarn can be made of functional fibers that are excellent in heat retention and other properties, thereby achieving both design and comfort and heat retention and other functions, and thus enabling the textile product to be flexibly designed with various characteristics according to the purpose.

[0063] (2) The second pile yarn is a covering yarn having a core yarn having a thickness of 10 to 30 denier wrapped around a sheath yarn having a thickness of 170 to 210 dtex. This has the effect of providing a textile product having an excellent wearing feel, in which even when a thicker pile layer is formed, the first pile layer is well supported and the heat retention and design properties are maintained for a long period of time, while the knitted structure does not become too dense and stiff, resulting in a lack of flexibility.

[0064] Furthermore, when the thickness of the second pile yarn is 10 to 20 denier, a supple knitted structure with a softer touch can be obtained, and a textile product with excellent wearing comfort can be provided. In particular, when the thickness of the second pile yarn is 10 denier, the best wearing comfort can be obtained, and at the same time, up to this thickness, durability that satisfies practical needs can be maintained.

[0065] (3) The first pile yarn has a thickness of 2 / 24 to 2 / 32, so that when supported by the second pile, the first pile yarn does not easily become flat or crushed by friction or washing, and the textile product maintains excellent design such as color and luster, and excellent wearing comfort such as texture, suitable for use as a textile product for a long period of time. At the same time, by making the thickness of the first pile yarn within this range, the excellent wearing comfort such as texture is not lost.

[0066] Furthermore, when the first pile yarn has a pile count of 2 / 26 to 2 / 30, the durability, design, and comfort of the textile product can be improved. In particular, when the first pile yarn has a pile count of 2 / 28, the best overall results can be obtained.

[0067] Furthermore, by forming the first pile yarns from two or more strands, a denser pile layer can be obtained, making it possible to provide a textile product with improved appearance and cold protection performance.

[0068] (4) The second pile yarn is a covering yarn in which a polyurethane elastic fiber yarn is wrapped with either a polypropylene resin fiber yarn, a nylon resin fiber yarn, or a polyester resin fiber yarn, so that it has the effect of realizing good heat retention, strength, and productivity. The design and wearing comfort of the textile product according to the present invention are determined to a considerable extent by the selection of the first pile yarn constituting the first pile, but the heat retention, strength, and productivity are largely determined by the selection of the second pile yarn constituting the second pile.

[0069] The core yarn and sheath yarn of the covering yarn, which is the second pile yarn, are made of polyurethane elastic fiber yarn, and due to its excellent strength and elasticity, the supporting force of the second pile for the first pile is increased, resulting in a pile layer that is stable for a longer period of time.

[0070] Since the sheath yarn of the covering yarn, which is the second pile yarn, is either a polypropylene resin fiber yarn, a nylon resin fiber yarn, or a polyester resin fiber yarn, the sheath yarn has sufficient strength to withstand friction and the like. Furthermore, since the polypropylene resin fiber yarn is characterized by its low thermal conductivity and light weight, an effect is achieved in that a textile product with excellent heat retention can be obtained. In particular, this effect is more pronounced when a hollow yarn made of polypropylene material is included. In addition, by using a covering yarn as the second pile yarn, which is made of a polyurethane resin fiber yarn as a core wire and a type of yarn according to the purpose wrapped around it, the effect is achieved in that the textile product according to the present invention can be manufactured by a general knitting machine without using a special knitting machine by utilizing the elasticity. This makes it possible to provide the textile product according to the present invention at a lower cost through reduction in capital investment, etc.

[0071] Furthermore, when the second pile yarn is a covering yarn in which a moisture-absorbing heat-generating fiber is wound around a polyurethane elastic fiber yarn, not only is the productivity excellent as described above, but also a textile product is realized in which the heat-generating effect allows the wearer to feel immediate warmth when wearing the product.

[0072] Furthermore, the second pile yarn is a strong covering yarn in which polypropylene resin fiber, nylon resin fiber, or polyester resin fiber yarn is wrapped around a polyurethane elastic fiber yarn, which provides the effect of providing good cushioning properties in the thick portion.

[0073] (5) The first pile yarn is a blended yarn containing acrylic fiber and wool fiber, which provides the effect of realizing a textile product that is moisture-absorbent, comfortable to wear, has excellent color and luster, has a high designability, and is wrinkle-resistant. Furthermore, the use of acrylic fiber with moisture-absorbent heat-generating properties provides the effect of providing a feeling of warmth immediately after wearing the textile product.

[0074] In addition, since the first pile yarn is a blended yarn containing cotton fiber and polyester fiber, it is possible to realize a textile product which is extremely comfortable to wear and has particularly excellent durability.

[0075] Since the main yarn, reinforcing yarn, first pile yarn and second pile yarn are all made of different yarns suited to the respective required functions, it is possible to select the yarn having the optimum function without having to compromise on each yarn.

[0076] Since the reinforcing yarn is covered by the main yarn by 90% or more, and the second pile yarn is covered by the first pile yarn by 90% or more, it is possible to realize a textile product that is excellent in design and wearing comfort, as well as in strength and heat retention.

[0077] (6) Since the socks are made of the textile products described in (1) to (5) above, it is possible to provide socks that have a thick pile layer with excellent heat retention, have excellent design such as color and luster, are comfortable to wear, and are durable against friction and washing.

[0078] Furthermore, since the socks are partially provided with thicker sections, they are not bulky overall while maintaining the heat retention in key areas, and because only a small amount of yarn is needed to knit the socks, they can be provided at a relatively low cost.

[0079] (7) The leg warmers are the textile products described in (1) to (5) above, so they have the same effect as the socks described in (6). In addition, because they are leg warmers, wearing them does not interfere with wearing shoes.

[0080] (8) Since the arm warmers are the textile products described in (1) to (5) above, the same effects as those of the socks described in (6) can be obtained.

[0081] (9) The body warmer is a textile product as described in (1) to (5) above, and thus has the same effect as the socks described in (6). When the body warmer is a sleeper for an infant to wear when sleeping, the sleeper is a seamless knitted fabric with excellent heat retention, and the parts that come into contact with the skin can be made of a material that is less irritating to the skin (for example, the first pile layer can be made of cotton yarn), so that the sleeper is less likely to cause skin disorders even when used for infants with delicate skin. [Brief description of the drawings]

[0082] [Figure 1] FIG. 1 is an explanatory diagram showing a method for carrying out the present invention. [Diagram 2] 1 is a comparative photograph of the pile layer side of the knitted structure of the thick part of the textile product according to an embodiment of the present invention and a conventional example. [Diagram 3] 1 is a comparative photograph of the knitted fabric layer side of the knitted structure of the thick part of the textile product according to an embodiment of the present invention and a conventional example. [Figure 4] 1 is an explanatory diagram showing a method of implementing the sock according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0083] Hereinafter, a textile product according to the present invention will be described with reference to the drawings. EXAMPLES

[0084] FIG. 1 is an explanatory diagram showing the knitting structure of the thick part of the textile product according to the present invention. Since the feature of the textile product according to the present invention is the thick part, the knitting structure of the thick part will be explained below. However, the textile product according to the present invention may include a knitting structure other than the thick part, and since this part is a conventionally known structure, the explanation will be omitted. Also, although FIG. 1 is an explanatory diagram of the knitting structure, in order to make the figure easier to see, only one weft row constituting the knitting structure is shown with a solid line, and the upper and lower parts are shown with dotted lines. Also, for the knitting structure of the parts shown with these dotted lines, the display of the yarns constituting the pile layer is omitted, and only the yarns constituting the knitted layer are shown. This is also to make the figure easier to see and to help understand the features of the present invention more clearly.

[0085] The knitted layer (6) of the textile product according to the present invention is a knitted structure knitted by a so-called plated knitting technique, and a blended yarn of 80% acrylic fiber, 15% nylon fiber, and 5% wool fiber with a thickness of 2 / 28 is used as the main yarn (3) exposed on the outer surface when the textile product is worn. This realizes non-slip properties, strength, and a good appearance. In addition, by using the main yarn (3) of this thickness, the internal reinforcing yarn (4), the first pile yarn (1), and the second pile yarn (2) are covered and a beautiful appearance is obtained. As will be described later, if the second pile yarn (2) is two thin yarns, a good covering by the main yarn (3) is realized. If there is only one second pile yarn (2) (a thick yarn is used for the need of strength), the covering by the main yarn (3) is incomplete, and the design of the textile product is reduced.

[0086] The reinforcing yarn (4) is a covering yarn made of polyester fiber wrapped around a polyurethane elastic fiber yarn that generates strong tension and provides a moderate tightening when the textile product is worn. Specifically, an elastic yarn made of 40 denier polyurethane elastic fiber yarn covered with 75 decitex polyester fiber is used. The reinforcing yarn (4) and the main yarn (3) form a plain knit structure, but since the reinforcing yarn (4) is knitted so that it is covered by the main yarn (3) when viewed from the outer surface of the textile product (the downward direction in the figure), essentially only the knit structure made of the main yarn (1), which has excellent color and luster, is visible from the outside, resulting in a textile product with a highly designable design.

[0087] The pile layer (5) is composed of a first pile (5a) composed of a first pile yarn (1) and a second pile (5b) composed of a second pile yarn (2). As shown in the figure, the second pile yarn (2) is composed of two yarns to form the second pile (5b), which is located inside the first pile (5a).

[0088] The second pile yarn (2) is composed of two covering yarns, each made of a polyurethane elastic fiber yarn core wrapped with a polypropylene hollow fiber. Specifically, two 190 decitex polypropylene hollow fibers are used for a 10 denier polyurethane elastic fiber yarn. Polypropylene has excellent heat insulation properties due to its extremely low water absorption and low thermal conductivity, but it has the disadvantage that it easily accumulates sweat and causes discomfort when it comes into direct contact with the skin due to its low hygroscopicity, and is also too slippery. However, since the second pile (5b) is woven so as to be covered by the first pile (5a), such disadvantages are not apparent and only the excellent heat insulation properties are utilized. In addition, polypropylene hollow fibers are characterized by lower heat conductivity and lighter weight than simple polypropylene yarns, and are therefore adopted in this embodiment. In addition, by using two thin 10 denier core threads, the second pile (5b) supports the first pile (5a) while being well covered and difficult to see from the outside. Furthermore, the second pile yarn (2) is covered by the main yarn (3) constituting the knitted layer (6), so the design of the outer surface when worn is not impaired.

[0089] Next, the reason why polyurethane elastic fiber yarn is used as the core wire of the second pile yarn (2) is to obtain a structure in which the second pile (5b) is covered by the first pile (5a). That is, when knitting the thick part of the textile product according to this embodiment, the first pile yarn (1) mainly made of acrylic fiber, nylon fiber, and wool fiber, which have poor elasticity, and the second pile yarn (2) made of polyurethane elastic fiber yarn, which has excellent elasticity, are fed into the knitting machine at the same time under tension. In this way, the first pile yarn (1) and the second pile yarn (2) are hung on the pile sinker of the knitting machine, and piles of the same pile length are formed. However, since the second pile yarn (2) was an elastic yarn with tension applied, it stretches and shrinks when the tension is lost after knitting is completed, and the pile length formed becomes shorter. In this way, the second pile (5b) is formed having a pile length shorter than that of the first pile (5a), and as shown in the figure, the second pile is provided inside the first pile, resulting in a so-called double pile structure.

[0090] The advantage of this manufacturing method is that it makes it possible to manufacture the textile product of the present invention without making major modifications to knitting machines that have been used conventionally, thereby saving on the large investment required for the development of dedicated manufacturing equipment, etc., and making it possible to provide the textile product of the present invention at a lower cost.

[0091] In this embodiment, the first pile yarn (1) is made of a blended yarn of 50% acrylic fiber and 50% wool fiber with a thickness of 2 / 28. By making the first pile yarn (1) this thickness, the strength and durability required for ordinary textile products such as socks are obtained, and the second pile (5b) is well covered by the first pile (5a) and is not exposed on the surface, so that the wearing comfort and design are not impaired. In addition, in this embodiment, the first pile layer (1) is the wearing surface that directly contacts the skin, so it is preferable that it has moisture absorption properties to obtain an excellent wearing comfort and a feeling of warmth, and that it also has design properties because it is the surface that the wearer may see, even though it is the wearing surface, and the blended yarn of acrylic fiber and wool fiber satisfies these requirements. In addition, acrylic fibers that have moisture absorption and heat generation properties have been distributed in recent years, and selecting such fibers is more preferable in that it allows a more noticeable feeling of warmth when worn. Specifically, Ex (registered trademark), an acrylic moisture absorbing and heat generating fiber manufactured by Nippon Exlan Kogyo Co., Ltd., can be used.

[0092] 2 and 3 are comparative photographs of the pile layer side of the knitted structure of the thick part of the textile product according to an embodiment of the present invention and a conventional example. FIG. 2 is a comparative photograph of the pile layer side, and FIG. 3 is a comparative photograph of the knitted fabric layer side. In each figure, (A) is a photograph of the textile product according to the present invention, and (B) is a photograph of the textile product according to the conventional example. The textile product according to the conventional example has a double pile knitted structure in common, but the second pile yarn is knitted with only one covering yarn made of a 20 denier polyurethane elastic fiber yarn wrapped with a 190 decitex polypropylene resin fiber. In order to distinguish between the two, the first pile yarn is white in the textile product according to the present invention, while it is black in the conventional example. The main yarns have the opposite color scheme.

[0093] From Fig. 2, it can be seen that the pile layer side of the thick part of the textile product according to the present invention is covered with the first pile inside, giving a uniform appearance, whereas in the conventional example, the inside (i.e., the second pile and knitted layer) is partially exposed and not uniform. Also, from Fig. 3, the knitted layer side of the thick part of the textile product according to the present invention has a characteristic striped pattern with the main yarns densely exposed on the surface, whereas in the conventional example, the pile yarns are exposed, and the photographs shown in Figs. 2 and 3 show the superiority of the present invention in terms of design. In the conventional example, the second pile yarn and reinforcing yarn are exposed on the surface, so it is natural that they come into contact with the skin, impairing the wearing comfort, and the superiority of the present invention is also shown in terms of wearing comfort.

[0094] It goes without saying that the yarns constituting the textile product according to the present invention are not necessarily limited to those in the above-mentioned embodiment, and any selection is possible within the scope of the object of the invention and the means for solving the problems. For example, a mode in which a cotton yarn having an especially excellent feel is used as the first pile yarn (1) is a modification falling within the technical scope of the present invention that can be implemented by a person skilled in the art as necessary. EXAMPLES

[0095] 4 is an explanatory diagram of a sock as an embodiment of the textile product according to the present invention. The yarn used to knit the sock is the same as that described in Example 1.

[0096] In the socks according to the present embodiment, the soles of the feet are made into thick parts (8) in order to increase the heat retention (insulation) of the soles of the feet, which are likely to become cold when in contact with a cold floor or the like. The thick parts (8) are very thick and have high heat retention, which are characteristic of the textile products according to the present invention, and the wearer can stay comfortable even when standing on a cold floor without feeling cold. Furthermore, the thick parts (8) are not only thick, but also have good cushioning properties due to the presence of a second pile layer made of strong yarn (strong yarn), so that shocks during walking are absorbed and fatigue is prevented even when the socks are used as indoor shoes. In addition, in this embodiment, the parts other than the soles of the feet are made into knitted parts with a relatively thin thickness. This prevents the feet from feeling unnecessarily voluminous, reduces the amount of yarn required for knitting the socks, and makes it possible to provide the socks according to the present invention at low cost.

[0097] It is also possible to have the entire sock made of thick material. When the floor is cold and the temperature in the room is low, not only the soles of the feet but also the entire feet may become cold. In such cases, wearing socks made entirely of thick material with high thermal insulation can prevent the feet from getting cold.

[0098] In the above examples, the knitted layer is the outer surface (i.e., the surface that does not directly touch the skin) and the pile layer is the inner surface (i.e., the surface that directly touches the skin). Pile fabric made of yarns of appropriate material has excellent wearing comfort such as feel, and the knitted layer made of yarns mainly made of wool, which has excellent aesthetics, has excellent aesthetics, so this configuration is a preferred example. However, it is also possible to use the pile layer on the outer surface and create a design that makes use of its unique texture, reversing the front and back. In this case, it goes without saying that the type of yarn that makes up each layer can be changed as appropriate. [Industrial Applicability]

[0099] As described above, the present invention provides a textile product which ensures the stability of the pile layer, which was difficult to achieve with the conventional double pile knitting structure, can withstand long-term use even with a thicker pile knitting structure, and maintains excellent comfort and designability by covering the small loops constituting the inner layer with the large loops constituting the outermost layer, and thus has extremely high industrial value.
