Description

[Technical Field]

[0001] The present invention relates to knitted fabrics and garments. [Background technology]

[0002] Patent Document 1 discloses a knitted fabric with a fray prevention function, which includes a course in which cellulosic fibers and elastic fibers are plated and a course in which synthetic fibers and elastic fibers are plated. The knitted fabric with a fray prevention function can be used to make garments with a raw edge specification. Raw edge means that the edges of the garment are not treated with a fray prevention treatment such as sewing. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7357519 Summary of the Invention [Problem to be solved by the invention]

[0004] Cellulosic fibers such as rayon, cupra, and cotton are widely used as apparel materials because of their high water absorption and moisture absorption properties, pleasant texture, and other reasons. Synthetic fibers such as polyester, nylon, and acrylic are also widely used as apparel materials because they dry quickly, retain their shape, and are strong. To obtain the properties of both of these fibers, it is conceivable to interknit these fibers, as disclosed in Patent Document 1. However, when cellulosic fiber yarns and synthetic fiber yarns are interknitted, the strength of the cellulosic fiber is generally not as high as that of the synthetic fiber, so the cellulosic fiber yarns tend to break easily, and the knitted fabric may lack strength.

[0005] An object of the present invention is to provide a high-strength knitted fabric in which yarns containing mainly cellulosic fibers and yarns containing mainly synthetic fibers are interwoven, and a garment made therefrom. [Means for solving the problem]

[0011] [Figure 1] FIG. 2 is a diagram showing the structure of a knitted fabric according to one embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0012] A knitted fabric according to one embodiment of the present invention and a garment made therefrom will be described below with reference to the drawings. Note that the drawings are drawn in a schematic manner with objects appropriately omitted or exaggerated to facilitate understanding.

[0013] [1. Knitted fabric composition] The knitted fabric 1 according to this embodiment is a fabric that can be preferably used to make clothing, particularly underwear. FIG. 1 is a diagram showing the structure of the knitted fabric 1. As shown in the figure, the knitted fabric 1 is knitted with a first inelastic yarn 10, a first elastic yarn 11, a second inelastic yarn 20, and a second elastic yarn 21. More specifically, the knitted fabric 1 is a knitted fabric obtained by interknitting the first inelastic yarn 10 and the first elastic yarn 11 with the second inelastic yarn 20 and the second elastic yarn 21. That is, the knitted fabric 1 is an interknitted fabric in which a first course C1 knitted with the first inelastic yarn 10 and the first elastic yarn 11 and a second course C2 knitted with the second inelastic yarn 20 and the second elastic yarn 21 are alternately arranged. The first course C1 and the second course C2 are adjacent to each other in the wale direction. In the description of this embodiment, the first elastic yarn 11 of the first course C1 and the second elastic yarn 21 of the second course C2 are distinguished by being assigned different reference numerals, but they do not need to be different yarns and may be made of the same continuous yarn. In other words, different elastic yarns may be knitted into the first course C1 and the second course C2, respectively, or the same continuous elastic yarn may be knitted into them.

[0014] The first course C1 is knitted by plating knitting using the first inelastic yarn 10 as the ground yarn and the first elastic yarn 11 as the plated yarn. Therefore, in the knitted part of the first course C1, the ground yarn (first inelastic yarn 10) mainly appears on the outside, and in the purl part of the first course C1, the plated yarn (first elastic yarn 11) mainly appears on the outside. The second course C2 is knitted by plating knitting using the second inelastic yarn 20 as the ground yarn and the second elastic yarn 21 as the plated yarn. Therefore, in the knitted part of the second course C2, the ground yarn (second inelastic yarn 20) mainly appears on the outside, and in the purl part of the second course C2, the plated yarn (second elastic yarn 21) mainly appears on the outside. In FIG. 1, for ease of viewing, the first inelastic yarn 10 is shown in white, the second inelastic yarn 20 is shown in light gray, and both the first elastic yarn 11 and the second elastic yarn 21 are shown in dark gray. However, these threads 10, 11, 20, 21 may be of the same color or of different colors.

[0015] In the example of Fig. 1, the first course C1 and the second course C2 are arranged alternately row by row in the vertical direction. However, at least one of the first course C1 and the second course C2 may be arranged continuously in multiple rows in the vertical direction (a knitted fabric in which a pattern in which n rows of the first course C1 are knitted and then m rows of the second course C2 are knitted is repeated, and at least one of n and m is an integer of 2 or more), or the first course C1 and the second course C2 may be arranged alternately in different numbers of rows in the vertical direction (a knitted fabric in which a pattern in which n rows of the first course C1 are knitted and then m rows of the second course C2 are knitted is repeated, and n and m are different integers).

[0016] In the example of FIG. 1, the knitted fabric 1 is a flat knitted fabric and is rib knitted. However, this is not limiting, and the knitted fabric 1 may be knitted using other knitting methods, for example, jersey knitting. In the case of rib knitting, ribs are formed by knit stitches that are connected in the vertical direction, and purl stitches are formed between the ribs. In the example of FIG. 1, knit stitches and purl stitches are alternately arranged in the horizontal direction by one stitch each (1×1 rib knitting), but at least one of the knit stitches and purl stitches may be continuous in the horizontal direction by multiple stitches each (n×m rib knitting, where at least one of n and m is an integer of 2 or more), or the knit stitches and purl stitches may be alternately arranged in the horizontal direction by different numbers of stitches each (n×m rib knitting, where n and m are different integers). In the case of rib knitting, where knit stitches and purl stitches are alternately arranged in the horizontal direction by the same number of stitches each, the front and back of the knitted fabric 1 have the same appearance. In Fig. 1, the knitted fabric 1 is shown in a plan view, so the knitted stitches and purl stitches are equally noticeable, but in reality, the ribs made by the knitted stitches may protrude forward (outward) from the purl stitches sandwiched between the ribs. Therefore, in this embodiment, both the front and back surfaces of the knitted fabric 1 may have an appearance in which the ground yarns (the first inelastic yarn 10 and the second inelastic yarn 20) are prominent. On the other hand, in the case of plain knitting, the knitted fabric 1 has knitted stitches lined up on the front surface, with the ground yarns (the first inelastic yarn 10 and the second inelastic yarn 20) mainly appearing, and the back surface of the knitted fabric 1 has purl stitches lined up, with the plated yarns (the first elastic yarn 11 and the second elastic yarn 21) mainly appearing.

[0017] The knitted fabric 1 is a knitted fabric having a fray prevention function. The first elastic yarn 11 and the second elastic yarn 21 have heat fusibility, and the first elastic yarn 11 and the second elastic yarn 21 are melted by a heat setting process, thereby imparting a fray prevention function to the knitted fabric 1. The first elastic yarn 11 and the second elastic yarn 21 are fused to the first inelastic yarn 10 and the second inelastic yarn 20, respectively. Although not limited thereto, the temperature of the heat setting process can be approximately 160°C.

[0018] The first elastic yarn 11 and the second elastic yarn 21 are typically made of polyurethane, but are not limited to this example. For example, the first elastic yarn 11 and the second elastic yarn 21 can also be made of a polystyrene-based elastomer. The first elastic yarn 11 and the second elastic yarn 21 can be made of only the materials exemplified here (e.g., 100% polyurethane), or the materials exemplified here may be mixed with other materials. However, the first elastic yarn 11 and the second elastic yarn 21 preferably contain at least 50% by weight of the materials exemplified here, more preferably 70% or more, even more preferably 90% or more, and even more preferably 95% or more. The first elastic yarn 11 and the second elastic yarn 21 are typically filament yarns, and may be multifilament yarns, but are preferably monofilament yarns.

[0019] The total proportion (weight) of the first elastic yarn 11 and the second elastic yarn 21 contained in the knitted fabric 1 is preferably 5% or more, more preferably 8% or more, and even more preferably 10% or more. When the above numerical conditions are satisfied, the fray prevention function of the knitted fabric 1 is effectively exhibited. On the other hand, the total proportion (weight) of the first elastic yarn 11 and the second elastic yarn 21 contained in the knitted fabric 1 is preferably 20% or less, more preferably 18% or less, and even more preferably 15% or less.

[0020] The first inelastic yarn 10 is a yarn that mainly contains cellulosic fibers. In this specification, "mainly containing X" means that the yarn contains 50% or more X by weight. The cellulosic fibers referred to here include regenerated fibers such as rayon and cupra, and plant fibers (natural fibers) such as cotton and hemp. Cellulosic fibers are characterized by high water absorption and moisture absorption, and good texture. Therefore, the knitted fabric 1 into which the first inelastic yarn 10 is knitted also has high water absorption and moisture absorption, and good texture. The first inelastic yarn 10 may be a filament yarn or a spun yarn.

[0021] The first inelastic yarn 10 preferably contains 70% or more cellulosic fibers by weight, even more preferably 90% or more, even more preferably 95% or more, and may contain 100%. Examples of fibers other than cellulosic fibers that can be contained in the first inelastic yarn 10 include synthetic fibers such as polyester, nylon, and acrylic, and animal fibers (natural fibers) such as silk and wool. The first inelastic yarn 10 may also contain two or more types of cellulosic fibers. For example, the first inelastic yarn 10 may contain regenerated fibers such as rayon and cupra, and plant fibers such as cotton.

[0022] The second inelastic yarn 20 is a yarn that mainly contains synthetic fibers. Synthetic fibers here include polyester, nylon, acrylic, etc. Synthetic fibers are characterized by quick drying and shape retention. Therefore, the knitted fabric 1 into which the second inelastic yarn 20 is knitted also has quick drying and shape retention. The second inelastic yarn 20 may be a filament yarn or a spun yarn.

[0023] The second inelastic yarn 20 preferably contains 70% or more synthetic fibers by weight, even more preferably 90% or more, even more preferably 95% or more, and may contain 100% synthetic fibers. Examples of fibers other than synthetic fibers that can be contained in the second inelastic yarn 20 include regenerated fibers such as rayon and cupra, plant fibers (natural fibers) such as cotton and hemp, and animal fibers (natural fibers) such as silk and wool. The second inelastic yarn 20 may also contain two or more types of synthetic fibers.

[0024] The proportion (weight) of cellulosic fibers contained in the knitted fabric 1 is preferably 40% to 70%, and more preferably 45% to 65%. The proportion (weight) of synthetic fibers contained in the knitted fabric 1, excluding the first elastic yarns 11 and the second elastic yarns 21, is preferably 20% to 50%, and more preferably 20% to 45%.

[0025] The loop length of the first inelastic yarn 10 in the first course C1 (the average yarn length forming one loop) is defined as L1 (cm), and the number of wales per half inch of the first inelastic yarn 10 in the first course C1 is defined as N1w. Furthermore, the loop length of the second inelastic yarn 20 in the second course C2 (the average yarn length forming one loop) is defined as L2 (cm), and the number of wales per half inch of the second inelastic yarn 20 in the second course C2 is defined as N2w. Here, (L1×N1w) / (L2×N2w)≧1.01 is preferable, and (L1×N1w) / (L2×N2w)≧1.02 is more preferable. Note that L1×N1w represents the yarn length of the first inelastic yarn 10 per half inch in the first course C1, and L2×N2w represents the yarn length of the second inelastic yarn 20 per half inch in the second course C2. That is, (L1×N1w) / (L2×N2w) is the yarn length ratio of the first inelastic yarn 10 to the second inelastic yarn 20.

[0026] Incidentally, when a yarn containing mainly cellulosic fibers, such as the first inelastic yarn 10, is interknitted with a yarn containing mainly synthetic fibers, such as the second inelastic yarn 20, the yarn containing mainly cellulosic fibers is prone to breakage (severance), and the knitted fabric may lack strength, because cellulosic fibers (especially regenerated fibers) generally do not have as high strength as synthetic fibers. In this regard, when the yarn length ratio (L1×N1w) / (L2×N2w) satisfies the above numerical range, the yarn length of the first inelastic yarn 10, which has a relatively low strength, is longer than the yarn length of the second inelastic yarn 20, which has a higher strength, making the first inelastic yarn 10 less likely to break. As a result, the strength of the knitted fabric 1, in which these yarns 10, 20 are interknitted, is increased, and the knitted fabric 1 becomes less likely to break.

[0027] On the other hand, if the difference in yarn length between the first inelastic yarn 10 and the second inelastic yarn 20 becomes too large, the knitted fabric 1 may become wavy, degrading the quality of the knitted fabric 1. From the viewpoint of preventing this, (L1×N1w) / (L2×N2w)≦1.15 is preferable, and (L1×N1w) / (L2×N2w)≦1.10 is more preferable.

[0028] The density in the course direction per half inch of the knitted fabric 1 is defined as Dc ( / 0.5 inch), and the density in the wale direction per half inch of the knitted fabric 1 is defined as Dw ( / 0.5 inch). In this case, it is preferable that Dc≧25, and it is more preferable that Dc≧30. It is also preferable that Dc≦35. It is also preferable that Dw≧15. It is also preferable that Dw≦25. It is also preferable that Dc×Dw≧500 (where "×" represents a product). When the above numerical conditions are met, the stitches of the knitted fabric 1 are effectively closed and the knitted fabric 1 has a high density, thereby further increasing the strength of the knitted fabric 1. On the other hand, if the knitted fabric 1 becomes too high density, it becomes difficult to stretch, so it is preferable that Dc×Dw≦700.

[0029] The weight of knitted fabric 1 is 180 g / m 2 It is preferable that the following conditions are satisfied. Note that as the fabric weight increases, the fabric becomes stronger and less likely to tear, but the fabric becomes heavier and less likely to stretch. In this regard, when the above numerical conditions are satisfied, the knitted fabric 1 becomes light and stretches easily, and a garment that is light and comfortable to wear can be produced.

[0030] The thickness of the knitted fabric 1 is preferably 0.8 mm or less. When the above numerical conditions are met, the knitted fabric 1 becomes thin, and thus a garment that is light and comfortable to wear is produced. Furthermore, the thickness of the knitted fabric 1 is preferably 0.6 mm or more. When the above numerical conditions are met, the strength of the knitted fabric 1 is further increased.

[0031] The stretch percentage of knitted fabric 1 in the longitudinal direction is Rsw, the stretch percentage in the lateral direction is Rsc, and the average of the stretch percentages in the longitudinal and lateral directions is Rs_ave (= (Rsw + Rsc) / 2). In this case, it is preferable that Rsw ≧ 20%. It is also preferable that Rsc ≧ 90%, and more preferably that Rsc ≧ 100%. It is also preferable that Rs_ave ≧ 60%. When the above numerical conditions are met, clothing made from knitted fabric 1 stretches appropriately, making the clothing easy to wear and allowing the wearer to move easily. In other words, the clothing feels good to wear.

[0032] The recovery rate in the vertical direction of knitted fabric 1 is Rrw, the recovery rate in the horizontal direction is Rrc, and the average of the recovery rates in the vertical and horizontal directions is Rr_ave (= (Rrw + Rrc) / 2). In this case, it is preferable that Rrw ≧ 70%. It is also preferable that Rrc ≧ 65%. It is also preferable that Rr_ave ≧ 70%. When the above numerical conditions are met, a garment made from knitted fabric 1 will not remain stretched after it is taken off, will easily return to its original size before wearing, and will be less likely to lose its shape.

[0033] The above elongation and recovery rates are measured as follows and calculated according to the following formulas (1) and (2). First, the measurement location is a test room (JIS L 0105) under standard conditions of room temperature 20±2°C and relative humidity 65±4%. The measuring device is a tensile tester. The sample size is 200 mm in length and 100 mm in width (taken in the course direction and wale direction). The distance between chucks is 100 mm. The tensile speed is 200 mm / min. The sample is pulled to 4.91 N and then released (returning the sample to its original position) five times.

[0034] Elongation rate (%) = Elongation (mm) after applying a constant load (4.91 N) for the fifth time ÷ Original length (100 mm) × 100 (1) Recovery rate (%) = Work load (cJ) when the constant load (4.91 N) is removed for the fifth time ÷ Work load (cJ) when the constant load (4.91 N) is applied for the fifth time × 100 (2)

[0035] When the breaking strength in the longitudinal direction of knitted fabric 1 is Sw (N), the breaking strength in the transverse direction is Sc (N), and the average of the breaking strengths in the longitudinal and transverse directions is S_ave (= (Sw + Sc) / 2), it is preferable that S_ave ≧ 45N. Furthermore, when the breaking elongation in the longitudinal direction of knitted fabric 1 is Ew (%), the breaking elongation in the transverse direction is Ec (%), and the average of the breaking elongation in the longitudinal and transverse directions is E_ave (= (Ew + Ec) / 2), it is preferable that E_ave ≧ 200%. Furthermore, it is preferable that S_ave × E_ave ≧ 12000N%, and more preferably S_ave × E_ave ≧ 14000N% (note that "×" represents a product).

[0036] S_ave × E_ave, which is the product of the average breaking strength S_ave in the vertical and horizontal directions of knitted fabric 1 and the average breaking elongation E_ave in the vertical and horizontal directions of knitted fabric 1, is an index for comprehensively evaluating the strength and extensibility of knitted fabric 1, and can be an index representing the tear resistance of knitted fabric 1. Therefore, when the above numerical ranges are satisfied, knitted fabric 1 becomes less likely to tear when worn as clothing, etc.

[0037] It is also preferable that Sw×Ew≧9500N%, and Sc×Ec≧10000N%.

[0038] The breaking strength and breaking elongation are measured as tensile strength and elongation, respectively, according to JIS L 1096. More specifically, the knitted fabric is cut, and five sample pieces, each 200 mm long and 25 mm wide, are taken in the course direction and the wale direction. Using a tensile tester, the sample pieces are pulled at an elongation rate of 100% with a chuck distance of 100 mm, and the tensile strength (N) and elongation (%) at break of the sample pieces are measured five times, and the average values ​​of the five measurements are calculated to represent the breaking strength and breaking elongation, respectively.

[0039] [2. Clothing composition] From the knitted fabric 1 described above, garments with a raw-edged finish, particularly underwear, can be preferably produced. A garment with a raw-edged finish is one in which some or all of the edges of the garment are left raw. In raw-edged edges, fray prevention by sewing or the like is omitted. Garments include tops and bottoms. The edges of garments typically form openings, such as the neckline, cuffs, and hem of tops, and the waist and hem of bottoms. Tops refer to all garments worn on the upper body, including T-shirts, tank tops, camisoles, slips, bras, belly warmers, and other underwear. Bottoms refer to all garments worn on the lower body, including pants, shorts, leggings, tights, socks, and loincloths.

[0040] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention. [Example]

[0041] Examples of the present invention will be described below, but the present invention is not limited to the following examples.

[0042] Knitted fabrics according to Examples 1 to 6 and Comparative Examples 1 to 6 were prepared. The knitted fabrics of Examples 1 to 6 and Comparative Examples 1 to 6 were produced by interlacing the four yarns shown in Tables 1 and 3. More specifically, a first course knitted from a first inelastic yarn and a first elastic yarn and a second course knitted from a second inelastic yarn and a second elastic yarn were interlaced so that they were arranged alternately in rows in the vertical direction. The first course was plated knitted using one first inelastic yarn as a ground yarn and one first elastic yarn as a plated yarn, and the second course was plated knitted using one second inelastic yarn as a ground yarn and one second elastic yarn as a plated yarn. All of the knitted fabrics of Examples 1 to 6 and Comparative Examples 1 to 6 were bare rib knitted (1x1 rib knitted).

[0043] [Table 1]

[0044] [Table 2]

[0045] [Table 3]

[0046] [Table 4]

[0047] The knitting conditions for the knitted fabrics of Examples 1 to 6 and Comparative Examples 1 to 6 were as shown in Tables 1 and 3. Furthermore, the physical properties shown in Tables 2 and 4 were measured and calculated for the knitted fabrics of Examples 1 to 6 and Comparative Examples 1 to 6.

[0048] In Tables 1 to 4, (L1×N1w) / (L2×N2w)≧1.01, 500≦Dc×Dw≦700, basis weight≦180g / m 2 The background of the cells that do not satisfy the conditions of Rs_ave≧60%, Rr_ave≧70%, S_ave×E_ave≧12000N% are colored gray. As can be seen from these results, all of the knitted fabrics of Examples 1 to 6 that satisfy the condition of (L1×N1w) / (L2×N2w)≧1.01 are not only high in strength because they satisfy the same condition (i.e., the first inelastic yarn that mainly contains cellulosic fibers is longer than the second inelastic yarn that mainly contains synthetic fibers, and the first inelastic yarn is less likely to break), but are also light (basis weight≦180 g / m 2), the knitted fabrics were comfortable to wear (Rs_ave≧60%), resistant to deformation (Rr_ave≧70%), and resistant to tearing (S_ave×E_ave≧12000N%). Furthermore, the knitted fabrics of Examples 1 to 6 all had stitch densities within an appropriate range (500≦Dc×Dw≦700) (from the viewpoint of strength and stretchability). On the other hand, the knitted fabrics of Comparative Examples 1 to 6, which did not satisfy the condition (L1×N1w) / (L2×N2w)≧1.01, not only did they not ensure sufficient strength due to the failure to satisfy this condition, but also resulted in inferiority in at least one of lightness, comfort, resistance to deformation, and resistance to tearing. More specifically, the knitted fabrics of Comparative Examples 1 and 2 were prone to tearing (S_ave×E_ave<12000N%) due to their small basis weight. Furthermore, the knitted fabric of Comparative Example 1 was prone to losing its shape (Rr_ave<70%). The knitted fabrics of Comparative Examples 3 to 6 were tear-resistant (S_ave×E_ave≧12000N%), but had a large basis weight, were heavy, and were difficult to stretch, resulting in an uncomfortable fit (Rs_ave<60%). Furthermore, in Comparative Examples 1, 2, and 4 to 6, the stitch density did not fall within the appropriate range (500≦Dc×Dw≦700). [Explanation of symbols]
