Description

Technical Field

[0001] The invention relates to the field of fabric textiles, and mainly relates to a woven warp-knitting imitation fabric. Background Art

[0002] With the development of social economy and the improvement of people's living standards, people have higher and higher requirements for clothing. More and more people are pursuing clothing with casualness, slimness, style, etc., and also have higher demands for the comfort of clothing. Therefore, consumers hope that the appearance of the fabric has the style of traditional denim, and they also require it to be soft, light, comfortable, breathable, and have excellent elasticity.

[0003] The main advantages of woven fabrics are stable structure, diverse styles and appearances, smooth surface, and generally no sagging when draped, making them suitable for various cutting methods. However, their breathability, feel and other properties are not as good as knitted fabrics.

[0004] With the rapid development of knitting technology, the coil structure of knitted fabrics has made these excellent wearing properties possible, so weft knitted denim fabrics have appeared on the market. However, although weft knitted denim fabrics have good weft extensibility, they cannot meet the dimensional stability requirements of clothing and cannot meet the market requirements.

[0005] Warp knitted fabrics have different structures and styles from weft knitted fabrics. Warp knitted fabrics have the advantages of low shedding, firmness, and good dimensional stability. Through the adjustment of yarn raw materials, organizational structure and post-finishing, they can produce visual impact effects. However, warp knitting and weaving have high requirements for the strength and elongation of yarns. Chemical fibers are often used in production, and yarns spun from short fibers (such as cotton fibers) are rarely used. Because the strength of yarns spun from short fibers is not as good as chemical fibers such as polyester and nylon, the mechanical properties of cotton yarns are easily damaged due to tension fluctuations during the warp knitting and weaving process; and because yarns processed from short fibers have hairiness and cotton knots, the entangled and aggregated hairiness or cotton knots during the warp knitting or weaving production process will block the yarn reed and yarn guide needles, causing yarn breakage. Therefore, in addition to the requirements for yarn strength, yarns processed from short fibers have higher requirements for yarn hairiness in warp knitting production, and coarse yarns are more difficult to meet this requirement, which limits the appearance style of warp knitted fabrics.

[0006] In summary, the existing woven fabrics and knitted fabrics each have their own advantages and disadvantages. Traditional woven fabrics do not have the performance characteristics of warp knitted fabrics such as air permeability and feel, and the appearance style of warp knitted fabrics is not as varied as that of woven fabrics. There is no fabric on the market that has both the style of woven fabrics and the characteristics of warp knitted fabrics, so the existing technology needs to be improved. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a woven imitation warp knitted fabric. By improving the fabric structure, the fabric can have both the appearance style of a woven fabric and the characteristics of good air permeability and good feel of a warp knitted fabric, aiming to solve the problems of poor air permeability and feel of existing woven fabrics.

[0039] The disclosure below provides many different embodiments or examples to realize different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplicity and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0040] The present invention provides a woven warp knitting imitation fabric, comprising warp yarns and weft yarns, the warp yarns and weft yarns are mutually interwoven to form a fabric, the warp yarns and weft yarns are interwoven through a specific tissue structure to form a tight structure, so that the fabric has both the appearance style of woven fabrics and the characteristics of good air permeability and good hand feel of warp knitted fabrics. The fabric comprises a front side and a back side, the front side of the fabric has the style of woven fabrics, and the back side of the fabric, that is, the side close to the skin, has the air permeability and hand feel of warp knitted fabrics, so that the back side of the fabric has good skin-friendly and comfortable feeling.

[0041] Specifically, the woven warp-knitted fabric includes a first warp yarn, a second warp yarn, a first weft yarn, and a second weft yarn; the first warp yarn and the first weft yarn are interwoven to form the front side of the fabric, and the second warp yarn and the second weft yarn are interwoven to form the back side of the fabric; on the back side of the fabric, 7 to 15 weft weave points can be set between two adjacent groups of warp weave points on the second warp yarn, and the number of each group of warp weave points is at least 1. It should be noted that the first and second warp yarns are only for the convenience of description, and do not necessarily represent the number of warp yarns and weft yarns, but are only for the convenience of describing the fabric.

[0042] The first warp yarn 21 is interwoven with the first weft yarn 11 to form the front side of the fabric. The front side of the fabric can be designed according to different styles, such as 3 / 1 twill, which has a classic denim flavor. The second warp yarn 22 is interwoven with the second weft yarn 12 to form the back side of the fabric. By continuously setting a plurality of weft tissue points on the back side, the fabric has a small tightness after the second warp yarn 22 and the second weft yarn 12 are interwoven. When the fabric is compressed, it is easier to be compressed, which is beneficial to improving the air permeability, feel and fluffiness of the fabric. And because the second warp yarn 22 is continuously sunk under the second weft yarn 12, the second warp yarn 22 sunk at the bottom of the weft yarn (a general term for the first weft yarn 11 and the second weft yarn 12) will form a larger coil with a certain curvature, such as Figure 1 As shown, since there are a plurality of loops with a certain curvature formed by the second warp yarn 22 on the back of the fabric, there are more air storage spaces 30 between the second warp yarn 22 and the weft yarn, so that the back of the fabric feels soft, has good air permeability and good fluffiness. Therefore, the back of the fabric of the present invention is comfortable when in contact with the skin.

[0043] Because the fabrics are processed by desizing, alkali boiling, washing and other treatments during the post-finishing treatment, if there are too many weft tissue points, the yarn fibers that are not interwoven between the warp and weft yarns will hug each other and not be tight, the hairiness on the yarn surface will increase, causing certain damage to the strength of the yarn, and the yarns will be entangled with each other. The back of the fabric is in contact with the skin, and it rubs against the skin during daily wear, making the entanglement or cross-entanglement between the yarns more serious, seriously affecting the style and feel of the fabric. If there are too few weft tissue points, the warp and weft yarns are interwoven more tightly on the back of the fabric, and the fabric is not easy to be stretched, so that some parts of the human body are subjected to great force when wearing it, and there is a sense of squeezing, which leads to an uncomfortable feeling of wearing. Therefore, in the present invention, preferably, 7 to 11 weft tissue points can be set between two adjacent groups of warp tissue points on the second warp yarn, and there will be no entanglement between the yarns, and the fabric interweaving tightness is moderate within this range. Most preferably, 8-piece 3-fly weft satin is used on the back of the fabric. After many trial weaving results, it was found that 8-piece 3-fly weft satin is used on the back of the fabric for the best effect.

[0044] Moreover, if there are too many weft weave points, the cloth will wrinkle and the texture will be blurred due to the large difference in shrinkage between the upper and lower layers. After a lot of experiments and trial weaving, it was found that the cloth with 7-11 floating lines will have better texture and the warp shrinkage will not be too large. Moreover, using fabrics within this range, the second warp yarn forms a coil with a certain curvature, the curvature is moderate and the coil is upright, with good air permeability, good feel, and the best fluffiness.

[0045] Preferably, the number of each group of warp points is preferably 1-2, because this can make the intervals between adjacent coils with a certain curvature small, and the coils with a certain curvature are distributed on the back of the fabric to the greatest extent, making the fabric feel soft to the touch.

[0046] The first warp yarn and the second warp yarn can be the same yarn or different yarns, the first weft yarn and the second weft yarn can be the same yarn or different yarns, the first warp yarn is elastic yarn or inelastic yarn, the first weft yarn is elastic yarn or inelastic yarn, the second warp yarn is elastic yarn or inelastic yarn, and the second weft yarn is elastic yarn or inelastic yarn. Among them, the inelastic yarn can be all yarns without elasticity in the prior art, such as cotton yarn, Tencel, Modal, wool yarn, Tencel-cotton blended yarn, cotton-modal blended yarn, etc. The elastic yarn can be all yarns with elasticity in the prior art, such as single core-spun yarn and double core-spun yarn, and more specifically, it can be cotton yarn wrapped with spandex, cotton yarn wrapped with polyester and spandex, cotton yarn wrapped with chemical fiber elastic yarn, etc.

[0047] Furthermore, the first weft yarn and the second weft yarn can be elastic yarns, so that the weft direction of the woven warp-knitted fabric is elastic and easy to stretch. The elastic weft direction is combined with the coils with a certain curvature in the warp direction, so that the pressure in the warp and weft directions can be reduced when the human body is wearing it, and the fabric is more comfortable to wear.

[0048] Furthermore, the first warp yarn can be made of elastic yarn, and the second warp yarn can be made of inelastic yarn or yarn with lower elasticity, and the shrinkage rate of the first warp yarn is more than 5% greater than that of the second warp yarn. Since the first warp yarn is made of elastic yarn and the second warp yarn is made of inelastic yarn or yarn with lower elasticity, after the fabric is subjected to conventional post-finishing treatment, the interweaving of the first warp yarn and the first weft yarn will shrink more than that of the second warp yarn and the second weft yarn, which will make the arrangement of multiple coils with a certain curvature on the back of the fabric more compact, and the coils with a certain curvature will form a larger curvature, so that more space for storing air is formed on the back of the fabric, and the fabric surface is more fluffy, light, and has better air permeability and hand feel. Compared with woven fabrics of the same thickness, the woven warp-knitted fabric of the present invention is lighter in weight and more fluffy in hand feel.

[0049] For people wearing clothes, the most important thing is that the human body feels comfortable when wearing them. In certain positions (such as the buttocks, knees, etc.), the clothes will produce a certain sense of pressure on these positions when the human body moves, so that people feel tight and stressed when wearing them, and the comfortable effect cannot be achieved. In order to solve this problem, the warp yarn and the weft yarn can be made of elastic yarn to make a four-way elastic fabric, so that the fabric is easier to stretch in the warp and weft directions, reducing the pressure of the clothing on the human body. The fabric is easy to stretch is an important feature that consumers feel the comfort of clothing. The elastic warp yarn and the elastic weft yarn are interwoven to form a single-layer four-way elastic fabric. The fabric will shrink. After shrinkage, the fabric surface is uneven and easy to wrinkle, which seriously affects the appearance and feel of the fabric. At the same time, the shrinkage rate in the warp direction is large, which causes the elastic fabric to curl when cutting, seriously affecting the production efficiency. For the existing double-layer elastic fabric, in order to make the fabric have 360-degree elasticity, the warp yarn with or without elasticity and the elastic weft yarn can be interwoven into the upper layer of the fabric, and the warp yarn with or without elasticity and the elastic weft yarn can be interwoven into the lower layer of the fabric, so that the double-layer fabric has the effect of four-way elasticity. However, the warp and weft directions of the existing double-layer elastic fabrics shrink after being processed, so that the warp and weft directions of the fabric are close to each other. Although the elastic performance of the fabric is excellent, the fabric is very tight. When a person squats, stands up or exercises while wearing the double-layer elastic fabric, some parts such as the buttocks and knees will feel pressured, making people feel uncomfortable, which is not suitable for the comfort requirements of clothing.

[0050] The woven warp-knitted fabric described in the present invention can solve the discomfort caused by the pressure. When the first warp yarn is elastic yarn and the second warp yarn is inelastic yarn or yarn with low elasticity, the woven warp-knitted fabric also has the characteristics of four-way stretch. Since the shrinkage of the fabric made of elastic yarn is greater than that of the fabric made of inelastic yarn, the front side of the fabric woven with elastic yarn will shrink, making the warp and weft yarns on the front side of the fabric more tightly interwoven, and the front side of the fabric shows the style of woven fabric, which meets people's pursuit of the style of woven fabric; due to the special organizational structure provided by the present invention, the second warp yarn and the second weft yarn are not tightly interwoven, and the back side of the fabric has the characteristics of weft knitted fabric, with low tightness, so that the back side of the fabric feels soft to the touch, and the coils with a certain curvature are relatively parallel to the skin. When the skin and the fabric rub up and down, the coils with a certain curvature are all along the movement direction of the skin, which can greatly reduce the discomfort caused by the fabric to the skin. More preferably, when the first warp yarn is made of elastic yarn and the second warp yarn is made of inelastic yarn, the first weft yarn and the second weft yarn are also made of elastic yarn, so that the woven imitation warp knitted fabric will have better elasticity, be easier to stretch, and have a soft feel.

[0051] The density of warp and weft and the thickness of yarn count can determine the surface density of the fabric. The thicker the yarn count, the greater the density, the greater the coverage of the fabric, the smaller the tightness of the fabric, and the more conducive to the fluffiness of the fabric. The first warp yarn and the first weft yarn constitute the front side of the fabric, and the second warp yarn and the second weft yarn constitute the back side of the fabric. When the ratio of the first warp yarn to the second warp yarn is 2:1 to 1:3, the yarn count of the first warp yarn is preferably thicker than the second warp yarn, so that the coverage of the first warp yarn on the front side of the fabric is large, while the coverage of the second warp yarn on the back side of the fabric is small, which is conducive to the fluffiness of the fabric. Moreover, the average yarn count of the back side of the fabric is thicker than the front side, which has a greater impact on the appearance of the front side of the fabric, and will make the texture on the front side of the fabric unclear. Therefore, it is preferred that the yarn count of the first warp yarn is thicker than the second warp yarn to ensure that the texture on the front side of the fabric is clear.

[0052] The first warp yarn and the second warp yarn can both be yarns made of short fibers or filaments, and the materials and yarn counts of the first warp yarn and the second warp yarn can be set to be the same or different as needed. Taking the first warp yarn as an example, the short fibers can be cotton fibers, linen fibers, Tencel, Modal, viscose, rayon, polyester, nylon, etc., preferably cotton fibers, and the yarn count range of the first warp yarn can be 6S~60S, including the two end values ​​of 6S and 60S. If the first warp yarn is made of yarn made of filaments, the yarn count range can be 40D~600D. If the first warp yarn is elastic, the yarn can be a short fiber coated elastic yarn processed into an elastic core-spun yarn (such as a short fiber coated spandex yarn) or an elastic core-spun yarn made of a filament coated elastic yarn. If the first warp yarn is made of a short fiber coated elastic yarn into an elastic core-spun yarn, the overall yarn count range is 6S~60S, and the elastic yarn range is 20D~300D. When the first warp yarn or the second warp yarn is an elastic core-spun yarn made of staple fiber coated elastic yarn, the overall yarn count range is 40D~600D, and the elastic yarn range is 20D~300D. The first warp yarn can be a single core-spun yarn or a double core-spun yarn, for example, cotton yarn wrapped in lycra, cotton yarn wrapped in polyester wrapped in lycra, cotton yarn wrapped in chemical fiber elastic yarn wrapped in lycra, cotton yarn wrapped in chemical fiber elastic yarn, etc. The optional range of the second warp yarn is the same as that of the first warp yarn.

[0053] The first weft yarn and the second weft yarn can both be yarns made of short fibers or filaments, and the materials and yarn counts of the first weft yarn and the second weft yarn can be set to be the same or different as needed. Taking the first weft yarn as an example, if the first weft yarn is a yarn made of short fibers, the yarn count range can be 6S~60S. If the first weft yarn is a yarn made of filaments, the yarn count range can be 40D~600D. If the first weft yarn is elastic, the yarn can be a short fiber coated elastic yarn processed into an elastic core-spun yarn (such as a short fiber coated spandex yarn) or a filament coated elastic yarn processed into an elastic core-spun yarn. If the first weft yarn is processed into an elastic core-spun yarn by using short fibers coated elastic yarn, the overall yarn count range is 6S~60S, and the elastic yarn range is 20D~300D. When the first weft yarn or the second weft yarn is an elastic core-spun yarn made of filament-covered elastic yarn, the overall yarn count range is 40D~600D, and the elastic yarn range is 20D~300D. The first weft yarn can be a single core-spun yarn or a double core-spun yarn, for example, cotton yarn wrapped with spandex, cotton yarn wrapped with polyester wrapped with spandex, cotton yarn wrapped with chemical fiber elastic yarn, etc. The optional range of the second weft yarn is the same as that of the first weft yarn.

[0054] The woven warp-knitted fabric provided by the present invention has at least the following advantages:

[0055] 1. The fabric has both the appearance and style of woven fabric and the characteristics of good air permeability and good feel of warp knitted fabric.

[0056] 2. The fabric is fluffy and light. The woven imitation warp knitted fabric is formed by interweaving the first warp yarn and the first weft yarn to form the front side of the fabric, and the second warp yarn and the second weft yarn are interwoven to form the back side of the fabric. The multiple coils with a certain curvature formed on the back side of the fabric form more space for storing air, so that the woven imitation warp knitted fabric is lighter and feels fluffier than fabrics of the same thickness. Preferably, the first warp yarn is elastic yarn, and the second warp yarn is inelastic yarn. After the fabric is subjected to conventional post-finishing treatment, the interweaving of the first warp yarn and the first weft yarn will shrink more than the interweaving of the second warp yarn and the second weft yarn, which will make the multiple coils with a certain curvature on the back side of the fabric more compact, and the coils with a certain curvature will form a larger curvature, so that the air permeability and hand feel of the fabric are better.

[0057] 3. Double-sided. Due to the double-layer structure of the first warp yarn and the second warp yarn interwoven separately, the warp yarn colors on both sides can be the same or different, which has stronger fashion expression and allows designers to have more room for creativity; at the same time, it also allows consumers to achieve the effect of wearing one piece of clothing in multiple ways.

[0058] 4. The fabric has a good hand feel. The present invention is a special fabric, and the coils with a certain curvature on the back of the fabric are vertically looped. When the skin and the fabric rub up and down, the coils with a certain curvature are along the movement direction of the skin, which can greatly reduce the discomfort caused by the fabric to the skin.

[0059] 5. High weaving efficiency. Although two kinds of weft yarns are used in the present invention, two systems of weft yarns can be used for weaving, or one system of weft yarns can be used for weaving. In the present invention, one system of weft yarns is preferred, because the warp density is greater than the weft density in the present invention, and the weft density setting difference during weaving is not much compared with that of a single-layer fabric, so the weaving efficiency is high and the time consumption is short.

[0060] The present invention is further described below by means of specific examples. Example

[0061] The organizational structure of the woven warp-knitted fabric of this embodiment is as follows: Figure 2 As shown, the colored grids represent the warp points, the blank grids represent the weft points, the front of the fabric is 3 / 1 right twill, and the back of the fabric is 8-piece 3-fly weft satin.

[0070] The woven warp-like fabric of this embodiment is subjected to conventional finishing process, and its performance data is tested. The test results are shown in Table 1. Among them, the air permeability of the woven warp-like fabric of this embodiment can reach 46.32 mm / s, which has good air permeability; the bulkiness can reach 356.45 cm 3 / g, good fluffiness.

The appearance of the woven warp-knitted fabric of this embodiment has the appearance style of woven fabric, such as clear twill lines, three-dimensional sense, and tight interweaving of warp and weft yarns. Due to the design of the organizational structure, the fabric feels soft and comfortable to the touch. When close to the skin, it has a skin-friendly touch, which is comfortable, soft and natural.

[0071] The basis for the relevant performance tests in the present invention is as follows:
