Description

Technical Field

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

[0002] With advancements in knitting technology, high-gauge knitted imitation woven fabrics have gained popularity in the trousers market due to their superior elasticity, memory properties, and softness against the skin. However, conventional imitation woven fabrics still fall short in achieving the crisp silhouette required for business trousers. The special structure of full-width weft-insulated warp-knitted fabrics can effectively solve this technical challenge. This technology optimizes fabric performance in two ways: first, by using low-stretch weft yarns to enhance fabric structure and dimensional stability, improving crispness; second, by incorporating high-elasticity weft yarns to create bi-directional stretch fabrics, balancing comfort and functionality.

[0003] At the same time, with economic development and social progress, environmental issues are becoming increasingly prominent. While traditional natural fibers are being replaced by synthetic fibers, man-made fibers, and blended fibers, a large amount of non-degradable waste fabrics and clothing is being generated, impacting sustainable environmental development. Therefore, the use of recyclable special raw materials from chemical fibers in warp knitting has become an urgent issue to be addressed.

[0004] Therefore, there is an urgent need to develop a warp-knitted imitation woven full-width weft-lined fabric that combines a crisp shape, excellent elasticity, and environmentally friendly properties to meet market demand. Utility Model Content

[0005] In view of the defects of the existing technology, the purpose of this utility model is to provide a warp-knitted imitation woven full-width weft-lined fabric that can overcome the above defects.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a warp-knitted imitation woven full-width weft-inserted fabric, comprising a fabric body, wherein the fabric body is a full-width weft-inserted warp-knitted structure formed by woven guide bars GB1, guide bars GB2 and weft-inserting guide bars, wherein guide bars GB1 and GB2 are both closed warp plain weaves with a weave structure of 1-0 / 1-2 / / , and the weft-inserting guide bars are full-width weft-inserted structures, wherein the yarn threading method of guide bars GB1, guide bars GB2 and weft-inserting guide bars is full threading, and the full-width weft-inserted warp-knitted structure is woven from polyester dull filament recycled yarn and spandex elastic fiber, with T400 bicomponent composite elastic fiber inserted, wherein the fabric has a warp density of 42 cpc and a weft density of 25.5 wpc.

[0007] Furthermore, the GB1 comb bar is made of recycled polyester dull filament yarn, the GB2 comb bar is made of spandex elastic fiber, and the weft comb bar is made of T400 bicomponent composite elastic fiber.

[0008] Furthermore, the specifications of the recycled polyester dull filament yarn are 30-50D, the specifications of the spandex elastic fiber are 40-70D, and the specifications of the T400 bicomponent composite elastic fiber are 30-50D.

[0009] Furthermore, the loop length of the polyester dull filament recycled yarn is 2.00-2.20 mm, and the loop length of the spandex elastic fiber is 1.30-1.50 mm.

[0010] Furthermore, the fabric is woven using a single-needle bed weft warp knitting machine with a needle density of 30-34 needles per inch.

[0011] Furthermore, the fabric has a weight of 150-160 g / m². 2 The fabric has a width of 135-145cm.

[0012] The beneficial effects of this utility model are as follows: This utility model proposes a warp-knitted imitation woven full-width weft-inserted fabric, which adopts a 1-0 / 1-2 / / closed warp plain weave structure of GB1 and GB2 guide bars, combined with a full-width weft-inserted structure, so that the fabric has both good crispness and elasticity, solving the problems of shape, elasticity and breathability of conventional imitation woven fabrics in business trousers. Secondly, it uses recycled polyester dull filament yarn with environmental protection properties as one of the raw materials, and combines recycled polyester dull filament yarn, spandex elastic fiber and T400 bicomponent composite elastic fiber to make the fabric have multi-dimensional elasticity and excellent shape recovery, making it comfortable to wear and not easy to deform, greatly extending the service life of the garment. Finally, by controlling the fabric density parameters of 42cpc in the warp and 25.5wpc in the weft, the optimal balance of the fabric structure is achieved, which ensures that the fabric texture is tight and maintains good hand feel and breathability.

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please see Figure 1This utility model provides an embodiment: a warp-knitted imitation woven full-width weft-inserted fabric, comprising a fabric body, wherein the fabric body is a full-width weft-inserted warp-knitted structure formed by woven guide bars GB1, GB2, and weft-inserting guide bars. Guide bars GB1 and GB2 are both closed warp plain weave structures with a 1-0 / 1-2 / / weave structure. The weft-inserting guide bars are full-width weft-inserted structures. The yarn threading method of guide bars GB1, GB2, and the weft-inserting guide bars is full threading. The full-width weft-inserted warp-knitted structure is woven from recycled polyester dull filament yarn and spandex elastic fiber, with T400 bicomponent composite elastic fiber intercalated. The fabric has a warp density of 42 cpc and a weft density of 25.5 wpc. GB1 follows a basic base fabric structure, plus the closed warp plain guide bar GB2. The fabric is fully threaded and smooth, with overlapping patterns with GB1, making the overall texture of the fabric more crisp. In addition, the full-width weft insertion comb significantly enhances the fabric's crispness, elasticity, and stability.

[0016] Please continue reading. Figure 1 As shown, in one embodiment of this utility model, the GB1 guide bar uses recycled polyester dull filament yarn, the GB2 guide bar uses spandex elastic fiber, and the weft guide bar uses T400 bicomponent composite elastic fiber. This technical solution uses recycled polyester dull filament yarn, which not only provides basic structural support for the fabric but is also environmentally friendly and reusable. The use of spandex elastic fiber provides excellent elastic recovery performance. The addition of T400 bicomponent composite elastic fiber weft yarn results in yarn with high tensile strength, 2-5 times that of ordinary polyester filament, and excellent recovery, maintaining an elastic recovery rate of over 95%. This yarn is not only fluffier and softer than ordinary polyester but also has good moisture-wicking properties, giving the fabric excellent wearing comfort, a soft hand feel, sweat absorption, and breathability. It is a key component in achieving a crisp and structured fabric shape.

Figure 1 As shown, in one embodiment of this invention, the loop length of the polyester matte filament recycled yarn is 2.00-2.20 mm, and the loop length of the spandex elastic fiber is 1.30-1.50 mm. By controlling the fabric density parameters, the optimal balance of the fabric structure is achieved, ensuring both a tight, snag-resistant fabric texture and good hand feel and breathability.

[0019] Please continue reading. Figure 1 As shown, in one embodiment of this utility model, the fabric is woven using a single-needle bed weft warp knitting machine with a needle density of 30-34 needles per inch.

[0020] Please continue reading. Figure 1 As shown in one embodiment of this utility model, the weight of the fabric is 150-160 g / m². 2 The fabric has a width of 135-145cm, which ensures both fabric strength and lightweight, comfortable wear.
