Description

Technical Field

[0001] This utility model relates to the field of warp-knitted fabrics, and more particularly to a composite fabric for softshell jackets. Background Technology

[0002] A softshell jacket is a garment that falls between a fleece jacket and a hardshell jacket. Its fabric is a composite of waterproof and fleece materials, offering both warmth and comfort, as well as waterproof and windproof properties. However, current softshell jackets on the market prioritize warmth, resulting in a slight decrease in waterproof performance.

[0003] Chinese patent application CN202111207321.5 discloses a composite fabric for a softshell jacket, comprising a fabric layer, a water-resistant layer, and a thermal insulation layer arranged sequentially from top to bottom; the water-resistant layer is a polyurethane film. The raw materials used in the fabric layer include the following components: 50-60 parts by weight of cotton fiber; 45-50 parts by weight of bamboo pulp fiber; 23-26 parts by weight of polyester fiber; and 30-35 parts by weight of waterproof finishing agent. The waterproof finishing agent is prepared by the following method: at a temperature of 25-30°C, water, methacryloxy polydimethylsiloxane, methyl methacrylate, butyl acrylate, emulsifier, initiator, n-hexadecane, and nano silica in a weight ratio of (8-10):(2-5):(1-1.5):(1-1.25):(0.16-0.2):(0.04-0.06):(0.16-0.19):(0.04-0.05) are mixed and homogenized for 30-40 minutes. Then, the mixture is reacted at a temperature of 68-72°C and a rotation speed of 300-320 r / min for 4-4.5 hours to obtain the waterproof finishing agent. By setting a water-blocking layer between the insulation layer and the fabric layer, a waterproof effect can be fully achieved, preventing external water and raindrops from penetrating the composite fabric and reaching the human body surface under certain pressure, thus improving the waterproof performance of the composite fabric. In addition, a waterproof finishing agent is used to waterproof the cotton fibers, bamboo pulp fibers, and polyester fibers in the fabric layer. Combined with the water-blocking layer, the synergistic effect between them is fully utilized, further improving the waterproof performance of the composite fabric.

[0004] While existing softshell fabrics strive for high elasticity to enhance wearing comfort, they often suffer from insufficient structural stability. For example, although a high proportion of elastic fibers improves tensile properties, it can easily cause the fabric to "show through" during vigorous stretching, affecting aesthetics and warmth. Furthermore, the fabric is prone to loosening and deformation after prolonged use, lacking sufficient support. Utility Model Content

[0005] Therefore, in view of the above problems, this utility model provides a softshell jacket composite fabric that can achieve two-way high elasticity and fit, ensure support and fixation, and has a good feel.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A softshell jacket composite fabric includes a warp-knitted fabric body comprising a face layer and a back layer. The face layer is woven from a first yarn and a second yarn, and the back layer is woven from a third yarn. The first yarn is nylon, the second yarn is spandex, and the third yarn is polyester fiber. The fabric body has knitting units distributed sequentially along the weft direction. Each knitting unit forms at least one elastic extension area and one support and fixing area in the warp direction. The back layer is connected to the face layer through a chain knitting structure. The elastic extension area forms a bidirectional elastic structure on the fabric body. The weight ratio of the first yarn to the second yarn in the face layer is 3-4:1 to achieve a close-fitting and breathable effect.

[0007] Furthermore, the first yarn accounts for 77% of the surface layer, and the second yarn accounts for 23%.

[0008] Furthermore, the coil length of the elastic extension region Coil length relative to the support fixed area The ratio relationship satisfies: 0 < ≤1.5, so that the fabric can deform to adapt to human movement when subjected to force.

[0009] Furthermore, the total weight of the top layer and the bottom layer is between 180 and 230 g / m², and the coverage of the top layer is... Total projected area of ​​the fabric body The ratio values ​​satisfy: ≥0.85, to prevent the fabric from showing through when stretched.

[0010] Furthermore, the first and second yarns are woven in the surface layer using a variable warp plain weave or a ply warp plain weave to form a matte surface texture.

[0011] Furthermore, the third yarn is fully woven in the bottom layer using a weft-insertion or warp-reinforced weave structure to enhance the fabric's abrasion resistance and structural stability.

[0012] Furthermore, the transverse density of the fabric body is between 25 and 40 loops per centimeter, and the longitudinal density is between 30 and 50 loops per centimeter.

[0013] Furthermore, the first yarn is a 70D to 140D nylon filament, the second yarn is a 20D to 40D spandex filament, and the third yarn is a 50D to 100D low-elastic polyester fiber filament.

[0014] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows: This softshell jacket composite fabric, by using a warp-knitted structure as the fabric body, utilizes the composite structure of the surface layer and the bottom layer to achieve functional zoning. Specifically, the surface layer is woven from nylon and spandex yarns, utilizing the high strength and abrasion resistance of nylon combined with the high elasticity of spandex to achieve excellent tensile recovery performance of the fabric body; the bottom layer is woven from polyester fiber yarns to provide dimensional stability; furthermore, by setting elastic extension areas and support and fixation areas, the fabric body can adapt to the deformation of human joint movement in the warp direction while providing necessary support and protection; at the same time, the bottom layer is connected to the surface layer through a chain structure, enhancing the interlayer bonding force and preventing delamination. In particular, by limiting the weight ratio of nylon yarn to spandex yarn to 3-4:1, while ensuring high elasticity, the coverage of nylon yarn effectively prevents the bottom layer from showing through when the fabric is stretched, achieving a unity of comfortable fit and aesthetic integrity. Attached Figure Description

[0015] Figure 1 This is a partially enlarged schematic diagram of the multi-layered weaving structure of the fabric body in an embodiment of this utility model. Detailed Implementation

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] The embodiment of this utility model is as follows: refer to Figure 1 As shown, a softshell jacket composite fabric includes a warp-knitted fabric body, comprising a face layer 1 and a back layer 2. The face layer 1 is woven from a first yarn 11 and a second yarn 12, and the back layer 2 is woven from a third yarn 21. The first yarn 11 is nylon, the second yarn 12 is spandex, and the third yarn 21 is polyester. The fabric body has knitting units distributed sequentially along the weft. Each knitting unit forms at least one elastic extension region A and a support and fixing region B in the warp direction. The back layer 2 is connected to the face layer 1 via a chain structure 3. The elastic extension region A forms a bidirectional elastic structure on the fabric body. The weight ratio of the first yarn 11 to the second yarn 12 in the face layer 1 is 3-4:1, preferably 3.35:1, to achieve a close fit and anti-permeability effect.

[0018] This softshell jacket's composite fabric utilizes a warp-knitted structure as its main body. The composite structure of the outer layer 1 and the inner layer 2 achieves functional zoning: the outer layer 1 is woven from nylon and spandex yarns, leveraging the high strength and abrasion resistance of nylon combined with the high elasticity of spandex for excellent tensile recovery; the inner layer 2 is woven from polyester fibers, providing dimensional stability; furthermore, by incorporating an elastic extension area A and a support and fixation area B, the fabric can adapt to the deformation of human joints in the warp direction while providing necessary support and protection; simultaneously, the inner layer 2 is connected to the outer layer 1 via a chain structure 3, enhancing interlayer bonding and preventing delamination. In particular, limiting the weight ratio of nylon to spandex yarns to 3-4:1 ensures high elasticity while effectively preventing see-through when the fabric stretches, achieving a balance between comfortable fit and aesthetic integrity.

[0019] Specifically, the first yarn 11 accounts for 77% of the surface layer 1, and the second yarn 12 accounts for 23%, which optimizes the elastic modulus of the fabric. The 23% spandex content ensures that the fabric has significant bidirectional elasticity, which can adapt to a large range of limb movements without causing a feeling of restriction; while the 77% nylon content ensures the abrasion resistance and tear resistance of the fabric surface, avoiding the problem of the fabric being too loose or losing strength due to excessive spandex content.

[0020] Furthermore, the coil length of the elastic extension region A Coil length relative to the supporting fixed area B The ratio relationship satisfies: 0 < The coil length is ≤1.5, allowing the fabric to deform in accordance with human movement under stress. Through differentiated coil length design, a "soft and hard" mechanical structure is formed on the fabric itself. The longer coils (elastic extension area A) provide greater extension space to adapt to the movement of joints such as elbows and knees; the shorter coils (support and fixation area B) form dense support points to prevent excessive fabric deformation. This allows the fabric to generate intelligent deformation in accordance with human movement under stress, improving the wearer's athletic performance.

[0021] Meanwhile, the total weight of the top layer 1 and the bottom layer 2 is between 180 and 230 g / m², preferably 210 g / m², and the coverage of the top layer is... Total projected area of ​​the fabric body The ratio values ​​satisfy: The yarn density is ≥0.85 to prevent the fabric from showing through when stretched. By setting the weight to 180-230 g / m², the fabric itself is lightweight and has a certain amount of insulating air layer, making it suitable for spring, autumn, or early winter wear. The high coverage index of ≥0.85 ensures structurally that even when the fabric is stretched, the yarn can be tightly covered, effectively preventing the internal structure from being exposed and ensuring the visual appeal and windproof and warm performance of the fabric in dynamic use scenarios.

[0022] In this embodiment, the first yarn 11 and the second yarn 12 are woven in the surface layer 1 using a variation of plain weave or a pile-pile plain weave, preferably a pile-pile plain weave, to form a matte finish surface texture. Compared to a regular plain weave, the pile-pile plain weave forms tiny geometric textures on the fabric surface, such as variations of diamond mesh or vertical stripes. This not only increases the diffuse reflection effect of the fabric surface, creating a high-end matte finish and enhancing the texture of the garment, but also makes the structure more stable, effectively suppressing loop skewing and improving the dimensional stability of the fabric.

[0023] Furthermore, the third yarn 21 is fully woven in the bottom layer 2 using a weft-insertion or warp-reinforced structure, preferably a weft-insertion structure, to enhance the fabric's abrasion resistance and structural stability. The full-weave method makes the bottom layer structure tight, greatly enhancing the fabric's abrasion resistance and anti-snagging ability. The introduction of the weft-insertion structure significantly improves the longitudinal and transverse stability of the fabric body without significantly increasing the fabric thickness, preventing the fabric body from curling after washing or long-term wear, and enhancing the durability of the softshell jacket.

[0024] Meanwhile, the transverse density of the fabric body is between 25 and 40 loops per centimeter, preferably between 35 loops per centimeter, and the longitudinal density is between 30 and 50 loops per centimeter, preferably between 45 loops per centimeter. This allows the fabric body to maintain a delicate feel while possessing good windproof performance and moderate breathability. The first yarn is 70D to 140D nylon filament, preferably 90D; the second yarn is 20D to 40D spandex filament, preferably 30D; and the third yarn is 50D to 100D low-elastic polyester fiber filament, preferably 90D. This achieves a comprehensive performance of lightweight, high elasticity, and durability in the fabric body.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
