[0002] As consumption concepts continue to evolve, consumers are placing higher demands on the durability, comfort, and versatility of clothing. Traditional woven fabrics lack sufficient elasticity in categories such as casual trousers, making it difficult to meet the specific garment requirements for structural fit and dynamic comfort. While weft-knitted fabrics offer better elasticity and processing flexibility, their shape retention and appearance are often inferior to woven fabrics.

[0003] Current weft-knitted fabrics cannot simultaneously possess the multiple advantages of low elasticity, good washability, excellent shape retention, high density, woven feel, and clear twill appearance.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0010] The third route consists of A needle floating thread, B needle tucking thread, and C needle floating thread;

[0011] The fifth row consists of A needle tucking, B needle floating thread, and C needle floating thread;

[0012] Among them, the first, third, and fifth lines correspond to the outer layer yarn, while the second, fourth, and sixth lines correspond to the inner layer yarn.

[0013] Furthermore, in the polyester elastic filament, the content of polybutylene terephthalate and / or polypropylene terephthalate is 30-100%, and the content of polyethylene terephthalate is 0-70%.

[0014] Furthermore, the outer layer yarn has a yarn length of 10.4~12.4cm / 100 stitches, and the inner layer yarn has a yarn length of 22~26cm / 100 stitches.

[0015] Furthermore, the luster of the polyester elastic filament is semi-dull or fully dull.

[0016] Furthermore, the outer short fiber yarn is pure cotton, polyester-cotton blend, or pure polyester short fiber yarn.

[0017] Furthermore, the linear density of the outer yarn is 30~40S, the linear density of the inner polyester elastic filament is 90~160D, and the linear density of the inner polyurethane filament is 30~55D.

[0018] Furthermore, the inner layer yarn is woven using a yarn-adding process.

[0019] Furthermore, the fabric is processed using a single-sided circular knitting machine, and the fabric is woven using the ABC stitch method, with a stitch length of 28~32G.

[0020] The second part of this invention provides a method for preparing a low-elasticity, tight-fitting, shuttle-feel weft-knitted twill fabric. This method is used to prepare any one of the low-elasticity, tight-fitting, shuttle-feel weft-knitted twill fabrics described in any one of the claims. The method includes the following steps:

[0021] The preparation method includes the following steps:

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Current weft-knitted fabrics cannot simultaneously possess the multiple advantages of low elasticity, good washability, excellent shape retention, high density, woven feel, and clear twill appearance.

[0045] To address the aforementioned issues, the applicant proposes a low-elasticity, tight-fitting, shuttle-feel weft-knitted twill fabric. The fabric comprises an outer layer and an inner layer. The outer layer yarn is a short-fiber yarn; the inner layer yarn is a blend of polyester elastic filament and polyurethane filament. The polyester elastic filament contains polybutylene terephthalate (PBT) and / or polypropylene terephthalate (PTT), wherein the content of PBT and / or PTT is ≥30%. Figure 1 and Figure 3As shown, the fabric's weave pattern consists of six repeats, and the weave pattern is as follows:

[0046] The first route consists of A needle floating thread, B needle floating thread, and C needle gathering thread;

[0047] The second, fourth, and sixth rows consist of A, B, and C needles all forming a loop;

[0048] The third route consists of A needle floating thread, B needle tucking thread, and C needle floating thread;

[0049] The fifth row consists of A needle tucking, B needle floating thread, and C needle floating thread;

[0050] Among them, the first, third, and fifth lines correspond to the outer layer yarn, while the second, fourth, and sixth lines correspond to the inner layer yarn.

[0051] The low-elasticity, tight-fitting, shuttle-feel weft-knitted twill fabric of the present invention has the following beneficial effects:

[0052] 1. The outer layer yarn is a short fiber yarn, which contains fuzz to ensure its natural appearance; the short fiber yarn gives the fabric the soft, warm, matte feel and appearance of natural fibers such as cotton, avoiding the plastic or shiny feel of chemical fiber filaments. The inner layer yarn is a blend of polyester elastic filament and polyurethane filament. The polyester elastic filament contains polybutylene terephthalate (PBTB) and / or polypropylene terephthalate (PPT). PBTB and PPT have high crimp values ​​and high shrinkage. The high crimp and high shrinkage characteristics of the inner layer polyester elastic filament cause shrinkage after heat setting, further tightening the outer short fiber yarn and forming a compact structure. PBTB and PPT are key to achieving low elasticity. These two elastic materials not only have a moderate modulus, providing moderate rather than excessive elasticity, but also have moderate elongation, giving the fabric a tight and crisp feel. There is no feeling of restriction when squatting or stepping, but it returns to its original shape quickly and is not prone to loosening. The selection of inner and outer layer yarns allows the fabric to combine the appearance and feel of natural fibers, low elasticity, high tightness, and excellent shape retention, making it washable and resistant to deformation.

[0053] 2. It adopts a six-way single-cycle knitting structure that combines three-way staggered looping with full-needle looping, which cleverly forms a clear twill appearance on a single-sided circular knitting machine, visually highly imitating woven twill fabric.

[0054] In summary, the low-elasticity, tight-fitting, woven-feel weft-knitted twill fabric of this invention, with its inner and outer layer yarns and a six-way loop knitting pattern working together, produces a high-performance knitted fabric on a regular single-jersey. This fabric features a clear and crisp twill weave on the front, resembling a woven fabric, a smooth and skin-friendly lining, and overall low-elasticity, tightness, and washability, perfectly balancing appearance and dynamic comfort.

[0055] Specifically, in the polyester elastic filament, the content of polybutylene terephthalate and / or polypropylene terephthalate is 30-100%, and the content of polyethylene terephthalate is 0-70%.

[0056] By adjusting the blending / copolymerization, a continuous adjustable range from "elasticity-dominant" to "rigidity-dominant" is achieved, thereby precisely customizing the "low-elasticity and tightness" of the fabric. This avoids the excessive looseness and elasticity of pure spandex while overcoming the stiffness and lack of elasticity of pure PET, and simultaneously takes into account performance, process compatibility, and economic cost. This is the key material guarantee for achieving the woven hand feel and weft-knitted elasticity goals of this invention.

[0057] Preferably, in the polyester elastic filament, the content of polybutylene terephthalate and / or polypropylene terephthalate is 50-70%, and the content of polyethylene terephthalate is 30-50%.

[0058] This configuration gives the fabric a hand feel closest to traditional woven twill, while retaining sufficient weft elongation, achieving the optimal balance between woven feel and elasticity. With this ratio, the fabric offers advantages such as low elasticity, high density, high bending stiffness, and economical price.

[0059] Specifically, the outer layer yarn has a yarn length of 10.4~12.4cm / 100 stitches, and the inner layer yarn has a yarn length of 22~26cm / 100 stitches.

[0060] This setting is key to achieving low elasticity, high tightness, and a woven feel.

[0061] The outer yarn has a length of 10.4~12.4cm / 100 stitches, which indicates that the outer yarn is shorter and has the following advantages:

[0062] 1. It can give the fabric high tightness: This means that the loops formed by each knitting needle are smaller and tighter. The outer short fiber yarn is woven with this short yarn long, the loops are tightened, the fabric surface has high density and small pores, the hand feel is tight and stiff, and there is obvious rebound resistance when pressed, which is close to the "bony" feel of woven fabric.

[0063] 2. Enhances the appearance of the diagonal pattern: The tight coil structure can better fix the diagonal texture formed by the coils, making the pattern clear, continuous and three-dimensional, and will not become blurred or deformed due to loose coils.

[0064] 3. Improved shape retention: Shorter yarn length reduces the space for yarn movement in the loops, resulting in greater resistance to fabric recovery after stretching. This makes it less prone to plastic deformation and allows the fabric to remain flat and prevent arching even after multiple wears and washes.

[0065] The inner layer yarn has a length of 22-26cm / 100 stitches, which indicates that the outer layer yarn has a longer length, offering the following advantages:

[0066] 1. Provides controllable elasticity: The longer yarn length means that the loops formed by the inner polyester elastic filaments (including PBT / PTT) and polyurethane filaments are looser and have more spare length. When the fabric is stretched, these loose loops can be straightened first without generating large stress, thus providing mild, low-modulus stretch to meet the needs of dynamic activities such as squatting and striding, but without being overly loose like highly elastic knitted fabrics.

[0067] 2. Avoid excessive shrinkage of spandex: If the inner layer yarn is too short (e.g., <22cm), the elastic yarn such as spandex will be stretched excessively, resulting in excessive shrinkage force of the fabric, a stiff hand feel, and excessive elasticity, deviating from the "low elasticity" target; if the inner layer yarn is too long (e.g., >26cm), the loops will be too loose, and the fabric will be prone to deformation, wrinkling, and lack of tightness.

[0068] In summary, the synergistic effect of the yarn length settings of the inner and outer layers results in a fabric that is tightly shaped and has a defined texture on the outer layer, while the inner layer is loose and cushioned for comfort and freedom of movement. The differential synergy between the inner and outer layers achieves a perfect balance between low elasticity, high recovery, woven hand feel, and weft elasticity.

[0069] Specifically, the luster of the polyester elastic filament is semi-dull or fully dull.

[0070] This setup completely eliminates the synthetic aurora effect of the inner elastic filaments at extremely low cost, making the fabric visually and tactilely highly consistent with the appearance of natural cotton / woven fabric. The semi-dull / full-dull inner filaments make the overall fabric reflective softly and the color deep and full, avoiding the whitening and floating effect caused by shiny filaments, significantly improving the product's grade. At the same time, it unexpectedly brings multiple advantages such as more uniform dyeing, higher color fastness, more stable heat setting, and safer singeing treatment.

[0071] Specifically, the outer short fiber yarn is pure cotton, polyester-cotton blend, or pure polyester short fiber yarn.

[0072] Specifically, the linear density of the outer yarn is 30~40S, the linear density of the inner polyester elastic filament is 90~160D, and the linear density of the inner polyurethane filament is 30~55D.

[0073] This set of parameters ensures that the fabric is neither as stiff and inelastic as pure woven fabric, nor as soft and easily deformed as ordinary weft-knitted fabric, but rather achieves multiple advantages of low elasticity, high tightness, and woven hand feel.

[0074] Specifically, the inner layer yarn is woven using a yarn-adding process.

[0075] Specifically, the fabric is processed using a single-sided circular knitting machine, such as... Figure 3 As shown, the fabric is woven using the ABC stitch method, as... Figure 2 As shown, the needles are arranged in a step-by-step low row.

[0076] The fabric is processed using a single-sided circular knitting machine, eliminating the need for expensive double-sided jacquard machines or special equipment, resulting in low cost. Existing knitting factories can quickly switch production, leading to high production efficiency.

[0077] Specifically, the stitch count of the fabric is 28~32G.

[0078] The fabric has a stitch length of 28~32G, which enables the fabric to physically achieve a high-density, tight, and clear twill woven structure.

[0079] A second aspect of the present invention provides a method for preparing a low-elasticity, tight-fitting, shuttle-feel weft-knitted twill fabric, said method being used to prepare any one of the low-elasticity, tight-fitting, shuttle-feel weft-knitted twill fabrics described in any one of the claims, said method comprising the following steps:

[0082] Specifically, in step S2, the post-processing includes:

[0084] S22, singeing or enzyme washing for finishing;

[0085] S23, staining;

[0086] S24, Drying;
