Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, and in particular to a full-width weft-lined warp-knitted fabric. Background Technology

[0002] As people's living standards improve, their requirements for clothing have gone beyond simple covering and warmth. More people are focusing on the comfort of clothing, and the ability to maintain this comfort even after daily washing. Knitted fabrics are softer and more breathable than woven fabrics, better meeting people's comfort needs. Therefore, designing and weaving soft, comfortable, and elastic fabrics is the development direction of our textile and apparel industry. Fabrics produced by traditional warp knitting machines are widely used in trousers, underwear, swimwear, etc. However, warp knitting has high requirements for yarn quality. Short fibers must achieve high breaking strength and a certain degree of elasticity, and the yarn dryness must be high to meet the conditions for warp knitting production. It also requires advanced warping technology.

[0003] Currently, woven fabrics on the market are stiff but dense and not breathable, while single-needle bed warp-knitted fabrics have a simpler structure, are soft and breathable but not stiff.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a full-width warp-knitted fabric with weft-inserted woven fabric, which has the crispness of woven fabric while having the micro-elasticity, breathability and soft hand feel of knitted fabric.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a full-width weft-inserted warp-knitted fabric, wherein the warp-knitted fabric is composed of at least three types of yarns: polyester yarn, rayon / lyocell / solona blended yarn, and spandex yarn. The polyester yarn has a two-needle closed warp plain structure, the spandex yarn has a reverse two-needle closed warp plain structure, and the rayon / lyocell / solona blended yarn has a full-width weft-inserted structure. The polyester yarn, rayon / lyocell / solona blended yarn, and spandex yarn are fully threaded through the carding bar to form the fabric.

[0007] Furthermore, the rayon / lyocell / solona blended yarn is a short fiber with a yarn thickness between 40S / 1 and 26S / 1.

[0008] Furthermore, the polyester yarn has a thickness between 30-50 denier, and the spandex yarn has a thickness between 20-70 denier.

[0009] Furthermore, the polyester yarn comb and the spandex yarn comb are made with opposing warp pads, with the polyester yarn pad numbers being 1-0 / 1-2 / / and the spandex yarn pad numbers being 1-2 / 1-0 / / .

[0010] Furthermore, the rayon / lyocell / solona blended yarn has a full-width weft-insertion structure.

[0011] Furthermore, the warp feed rate of the polyester yarn comb and the rayon / lyocell / solona blend comb is 600-900 mm / gra, while the warp feed rate of the spandex yarn comb is 500-750 mm / gra.

[0012] Furthermore, the fabric is woven by a single-needle bed warp knitting machine with a needle count between 28 and 44 needles per inch.

[0013] The beneficial effects of this utility model are as follows: This utility model proposes a full-width weft-insulated warp-knitted fabric, which differs from most knitted fabrics on the market. Utilizing a single-needle bed three-comb weft-insulated warp knitting machine, it uses 40S / 1-26S / 1 rayon / lyocell / Sorona fibers, plus 30D-50D polyester and 20-70D spandex elastic yarns, and is woven using warping and specific weaving techniques. This gives the fabric the crispness of woven fabric while also possessing the advantages of knitted fabric such as elasticity and breathability. Furthermore, Sorona fiber and lyocell are added to the short fibers, making the blended short fibers more elastic, resilient, moisture-wicking, and breathable. Then, high-quality wax oil is applied to the surface of the short fibers, making the yarn surface smoother. This reduces the problem of yarn breakage caused by mechanical friction with the needles during weaving, thus affecting production. The final fabric has good dimensional stability and possesses crispness, elasticity, breathability, moisture-wicking, and comfort properties. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] Please see Figures 1 to 6This utility model provides an embodiment: a full-width weft-inserted warp-knitted fabric, wherein the warp-knitted fabric is composed of at least three types of yarns: polyester yarn, rayon / lyocell / solona blended yarn, and spandex yarn. The polyester yarn is a two-needle closed warp plain structure, the spandex yarn is a reverse two-needle closed warp plain structure, and the rayon / lyocell / solona blended yarn is a full-width weft-inserted structure. The polyester yarn, rayon / lyocell / solona blended yarn, and spandex yarn are fully threaded through the comb bar to form the fabric. The yarn used in the weft-inserted guide bars is a blended short fiber, including Sorona fiber, which makes the blended short fiber more elastic and tough. High-quality wax oil is then applied to the surface of the blended short fiber, making the yarn surface smoother and reducing yarn breakage due to friction with the needles during weaving, thus solving the production problems caused by yarn breakage in blended short fibers. The blended short fiber also contains lyocell, which has high strength and good moisture permeability and breathability, making the blended yarn less prone to breakage while also providing good breathability and moisture permeability. In addition, other guide bars use polyester and spandex yarns, and the fabric weave is a warp plain weave and full-width weft-inserted weave structure, resulting in a stable fabric structure and dimensions, with a slight elasticity and crispness.

[0022] Please continue reading. Figures 1 to 6 As shown in one embodiment of this invention, the rayon / lyocell / solona blended yarn is a short fiber with a yarn thickness between 40S / 1 and 26S / 1, the polyester yarn has a thickness between 30 and 50 denier, and the spandex yarn has a thickness between 20 and 70 denier. The unique properties of the rayon / lyocell / solona blended short fiber, combined with the good elasticity and shape retention of the polyester yarn and the excellent elasticity and tensile recovery of the spandex yarn, result in a fabric that is slightly elastic and breathable. Selecting specific yarn thicknesses ultimately yields a mesh fabric with a soft appearance and feel.

[0023] Please continue reading. Figures 1 to 6 As shown, in one embodiment of this utility model, the polyester yarn comb and the spandex yarn comb are made with opposing warp pads, the polyester yarn pad numbers are 1-0 / 1-2 / / , the spandex yarn pad numbers are 1-2 / 1-0 / / , and the rayon / lyocell / solona blended yarn has a full-width weft-insertion structure.

[0024] Please continue reading. Figures 1 to 6 As shown in one embodiment of this utility model, the warp feed rate of the polyester yarn guide bar and the rayon / lyocell / solona blend guide bar is 600-900 mm / lac, and the warp feed rate of the spandex yarn guide bar is 500-750 mm / lac. The warp feed rate is estimated when each guide bar follows the corresponding padding yarn number. During actual machine operation, the estimated warp feed rate can be used for material preparation and machine adjustments.

[0025] Please continue reading. Figures 1 to 6As shown, in one embodiment of this utility model, the fabric is woven on a single-needle bed warp knitting machine with a needle count between 28 and 44 stitches per inch. The fabric is woven using a single-needle bed three-comb weft-inserted warp knitting machine, employing 40S / 1-26S / 1 rayon / lyocell / Sorona yarns, plus 30D-50D polyester and spandex yarns, using warping and specific weave techniques. Finishing is then completed with the addition of a moisture-wicking agent. The resulting fabric possesses characteristics such as crispness, slight elasticity, and breathability.

[0026] Please continue reading. Figures 1 to 6 As shown, in one embodiment of the present invention, a warping step is included before weaving. In the warping step, the polyester is fed by a passive yarn feeding method, the warping temperature is 25°C, and the warping humidity is 65%; the spandex is fed by an active yarn feeding method, the warping temperature of the spandex is 24°C, and the warping humidity is 75%.

[0027] Please continue reading. Figures 1 to 6 As shown, the fabric weave is an elastic warp plain weave with a full-width weft-insertion structure. The front-combed warp plain weave GB1 uses 30D-50D polyester for full weave, with a warp feed of 600-900 mm / lagram. Figure 2 Medium comb GB2 uses 20D-70D spandex yarn in a full-length warp feed of 500-750 mm / lacquer. Figure 3 The weft insertion comb uses short-fiber 40S rayon / lyocell / solona-26S / 1 rayon / lyocell / solona full-width weft insertion, with a warp feed of 600-900 mm / lacquer.

[0028] Please continue reading. Figures 1 to 6 As shown, the basic yarn number of the flat comb GB1 is 1-0 / 1-2 / / . Based on 1-0 / 1-2 / / , a flat pattern is formed on the fabric surface. The yarn number of the spandex comb GB2 is 1-2 / 1-0 / / . The pattern is reversed from GB2, which makes the fabric surface flatter and more stable. In addition, the GB3 full-width weft insertion comb is fully inserted, which forms a mesh with several regular shapes on the weft insertion structure. At the same time, it makes the fabric crisp, slightly elastic and breathable.

[0029] Through the characteristics of blended short fibers and the special structure of full-width weft weaving, the fabric, after dyeing and finishing, has good dimensional stability and features crispness, slight elasticity, breathability, moisture wicking and comfort.
