[0001] The invention relates to a high-recovery fabric, in particular to a weft-knitted spacer fabric with enhanced recovery through inlay yarn. Background Art

[0002] As women's spending power increases, their living standards and health awareness gradually improve, yoga pants have gradually become a favorite of female consumers. Yoga pants, once only known to yoga enthusiasts, have now quietly become a hot item in the fashion industry. Not only can they be seen in gyms, but also on the streets, in offices and even on the red carpet. Behind this phenomenon, it reflects the new pursuit of health, comfort and fashion by modern women.

[0003] Behind the popularity of yoga pants are a series of wearing experience issues that urgently need to be improved. The most common feedback is that the fabric cannot return to its original state in time because it is tight between the body or after some stretching movements, such as squatting and other limb bending movements, resulting in wrinkles on the fabric and difficulty in recovering in a short time.

[0004] CN207388435U discloses: a sofa fabric with durable surface texture, which aims to solve the problem that due to the lack of recovery ability of traditional fabrics, the indentations on the surface of the fabric may be flattened after multiple compression and deformation, thereby losing the technical effect of improving the breathability. The key points of its technical solution are: a sofa fabric with durable surface texture, comprising a suede layer and a fleece layer arranged up and down, the surface of the suede layer is provided with indentations, the bottom surface of the suede layer is provided with a sanded layer, and the sanded layer is bonded with a memory cloth layer. The sofa fabric with durable surface texture of the present invention utilizes the recovery ability of the memory cloth so that the fabric can recover in time after being compressed and stretched, thereby avoiding the indentations on the surface of the fabric from being flattened.

[0005] CN118257042A discloses: a high-recovery weft elastic fabric and finishing process, belonging to the field of textile processing technology. Its technical solution is: the warp yarn adopts C / T / LYOCELL40 / 2, the weft yarn adopts moisture-absorbing and quick-drying yarn COOLPASS150D / 2, C / T / LYOCELL40 / 2 in a 1:1 ratio, the fabric specification is C / T / LYOCELL40 / 2*COOLPASS150D / 2+C / T / LYOCELL40 / 2*80*50*57 / 58, the structure is plain weave, including the following steps: cold stacking → washing → dyeing → air flow → drying → pre-shrinking. The present invention solves the problem of low recovery of elastic fabrics and improves the cost performance. At the same time, cotton polyester lyocell yarn is used to improve the fabric feel; the functional polyester filament has the effect of moisture absorption and quick drying, providing consumers with a better wearing experience.

[0006] CN114411317A discloses: a super elastic high recovery yoga knitted fabric and a preparation method thereof, comprising the following steps: raw materials: nylon yarn and spandex yarn; weaving process: using 40N high needle gauge weaving equipment to weave into a cotton wool structure with full spandex and nylon added yarn and a single-sided sweat cloth variable structure to make the fabric; pre-setting process: pre-setting the fabric obtained in the step 2, setting the setting machine temperature to 160-180°C, and the machine speed to 20-25m / min; dyeing process: the dyeing process includes pre-treatment, dyeing and post-treatment process flow; post-finishing process: dehydration after dyeing and softening, drying and shaping, the temperature is 120-130°C, and the machine speed is 15-25m / min. The yoga knitted fabric obtained by the super elastic high recovery yoga knitted fabric and the preparation method thereof provided by the present invention has a soft and comfortable feel, good air permeability, and has super high comfortable elasticity, recovery and coverage. "

The use of special yarns for weaving is not conducive to mass promotion and production; 2. Special process processing is required in production, which has high requirements for production equipment and operators. In addition, yoga pants are generally made of warp knitted fabrics, and there is little research and production on weft knitted fabrics.

[0008] In order to solve the above problems, it is imperative to develop a yoga pants fabric with ultra-high recovery and non-wrinkle properties. Summary of the invention

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] There are two ways of adding yarn. One is to use a relatively fixed number of yarns Y3 as the basis, and then add yarn Y4, and use yarn Y4 to control the spandex content of the middle connecting layer and use the material properties of yarn Y4 to enhance the warp and weft recovery, and enhance the compression recovery performance through the material properties of yarn Y4 and the number of DPFs; the other is to use a relatively fixed number of yarns Y4 as the basis, and then add yarn Y3, and use yarn Y3 to control the spandex content of the middle connecting layer to mainly enhance the compression recovery performance.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be directly connected or indirectly connected through an intermediate medium. It can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figure 1-4 As shown, a weft-knitted spacer fabric with enhanced recovery through added yarn comprises a fabric body, wherein the fabric body comprises a clothing layer 1, an intermediate connecting layer 2 and a skin-contacting layer 3 connected in sequence, the clothing layer 1 is woven by yarn Y1 and yarn Y2, the intermediate connecting layer 2 is woven by yarn Y3 and yarn Y4, the skin-contacting layer 3 is woven by yarn Y5 and yarn Y6, the yarn Y3 is spandex, the yarn Y4 is non-spandex, the yarn Y3 and the yarn Y4 are respectively looped back and forth on the clothing layer 1 and the skin-contacting layer 3 to form the intermediate connecting layer 2, the spandex content in the intermediate connecting layer 2 is 0%-60% and greater than 0%, and the maximum value is 60%, the strength of the yarn Y4 is greater than the strength of the yarn Y3, and the elongation of the yarn Y4 is less than the elongation of the yarn Y3; when weaving the intermediate connecting layer, the required number of yarn Y4 is added based on the fixed number of yarn Y3, or the required number of yarn Y3 is added based on the fixed number of yarn Y4. The spandex content in the middle connecting layer, that is, the content of the yarn Y3, is the ratio of the amount of the yarn Y3 used to the sum of the amounts of the yarn Y3 and the yarn Y4 used.

[0031] When yarn Y4 is added based on a relatively fixed amount of yarn Y3, the content of yarn Y3 in the middle connecting layer 2 is different when different amounts of yarn Y4 are added, that is, the spandex content in the middle connecting layer is controlled by adding yarn Y4. The more yarn Y4 is added, the lower the spandex content in the middle connecting layer 2, and vice versa. The spandex content in the middle connecting layer and the material properties of yarn Y4 are used to enhance the warp and weft recovery, and the compression recovery performance is enhanced by the material properties of yarn Y4 and the number of DPFs.

[0032] When yarn Y3 is added based on a relatively fixed amount of yarn Y4, the amount of yarn Y3 added is used to control the spandex content of the middle connecting layer 2 to mainly enhance the compression recovery performance. The more yarn Y3 is added, the higher the spandex content is, and vice versa.

[0033] The yarn Y4 has greater strength and smaller elongation than the yarn Y3 , and can reduce the coil deformation of the middle connecting layer 2 on the clothing layer 1 and the skin-contacting layer 3 .

[0034] The yarn Y1 and the yarn Y2 in the clothing layer are knitted by looping and tucking to form a plain or jacquard mesh structure, at least one of the yarn Y1 and the yarn Y2 is spandex, and the jacquard mesh structure is composed of a plurality of meshes, wherein the mesh area is 0%-50%, when it is 0%, there is no mesh, the highest selection value is 50%, and the spandex content in the clothing layer is 5%-26%. By selecting at least one yarn as spandex, it has good elasticity.

[0035] The yarn Y5 and the yarn Y6 in the skin-contacting layer are knitted by looping and tucking to form a plain or jacquard mesh structure, at least one of the yarn Y5 and the yarn Y6 is spandex, wherein the mesh area is 0%-20%, and the spandex content in the skin-contacting layer is 5%-40%. By selecting at least one yarn as spandex, it has good elasticity and forms a variety of appearance styles.

[0036] The yarn Y3 and the yarn Y4 of the middle connecting layer are used to connect the clothing layer and the skin-contacting layer to enhance the sliding friction between the layers. The yarn Y4 will not adhere to the yarn Y1, the yarn Y2, the yarn Y5 and the yarn Y6 due to high temperature setting, and the amount of yarn Y4 added will affect the contact area between the yarn Y3 and Y2 and Y6. When the amount of yarn Y4 added is large, the contact area between the yarn Y3 and the other yarns is small, and vice versa. In addition, the thickness of the yarn Y4 will also affect the adhesion effect between the yarns. The thickness relationship of each yarn is: yarn Y2≥yarn Y6≥yarn Y3. When the try-on is stretched, because the yarn Y4 has a large strength and a small elongation, the tensile deformation of the coil of the middle connecting layer 2 on the coil of the clothing layer 1 and the skin-contacting layer 3 can be greatly reduced, 100%<the coil deformation of the clothing layer 1 and the skin-contacting layer 3≤200%, which greatly enhances the warp and weft recovery of the fabric.

[0037] The yarn Y3 has a diameter of 15D-40D, preferably 20D-30D, and has a low spandex content, which improves the fluffiness of the fabric, but the compression recovery of the fabric is poor. When the spandex content is increased, the outward potential energy of the spandex in the thickness direction can be enhanced, and the work of the spandex in the thickness direction can be enhanced, thereby improving the compression recovery of the fabric.

[0038] The yarn Y4 is polyester, cotton, viscose, acrylic, modal, polypropylene or nylon, wherein the rigidity of each yarn is: polyester>cotton>viscose>acrylic>modal>polypropylene>nylon, the greater the rigidity, the better the warp and weft recovery, and the stronger the compression recovery. The DPF value affects the initial modulus of the yarn. When the DPF is larger, the initial modulus becomes larger and the compression recovery is stronger. When the DPF is smaller, the initial modulus becomes smaller and the compression recovery becomes weaker. Therefore, the DPF value of the yarn Y4 is selected between 0.42-20 and 0.8-10, the content of the yarn Y4 in the middle connecting layer is 60%-100%, the F number of the yarn Y4 is 1F-72F, and the wire diameter of the yarn Y4 is 10D-30D, which can achieve relatively good recovery without affecting the overall comfort of the fabric.

[0039] The yarn Y1 is polyester, nylon, cotton or modal, the content of the yarn Y1 in the clothing layer is 74%-95%, the line diameter of the yarn Y1 is 20D-150D, and the F number of the yarn Y1 is 12F-144F; the yarn Y2 is spandex, the content of the spandex in the clothing layer is 5%-26%, and the line diameter of the yarn Y2 is 20D-70D.

[0040] The yarn Y5 is polyester, nylon, cotton or modal, the content of yarn Y5 in the skin-contacting layer is 60%-95%, the diameter of yarn Y5 is 20D-150D, the F number of yarn Y5 is 12F-144F, yarn Y6 is spandex, the content of spandex in the skin-contacting layer is 5%-40%, and the diameter of yarn Y6 is 20D-70D.

[0041] When the yarn Y1 and the yarn Y2 in the clothing layer are woven by looping and tucking to form a jacquard mesh structure, and the yarn Y5 and the yarn Y6 in the skin-contacting layer are woven by looping and tucking to form a jacquard mesh structure, the shape and arrangement rules of the jacquard mesh structure in the clothing layer and the jacquard mesh structure in the skin-contacting layer are the same or different.

[0042] The longitude and latitude recovery is mainly tested through LTD03 7.5ibf test. Only when the longitude and latitude recovery rate growth rate is greater than 3% and the recovery data is ≥90%, it is proved that the longitude and latitude recovery function is enhanced.

[0043] Compression recovery is mainly expressed by the Compression Recovery Rate indicator in the FTT feel tester. Only when the compression recovery rate growth rate is greater than 3% and 0.4≤CRR≤1, it is proved that the compression recovery function is enhanced.

[0084] 1. According to the experimental results of Example 1 and Example 2 in Table 1, adding yarn Y4 based on yarn Y3 and adding yarn with greater strength and smaller elongation than spandex into the middle connecting layer 2 can not only enhance the warp and weft recovery rate, but also greatly improve the compression recovery performance.

[0087] 4. According to the experimental results of Example 1 and Example 5 in Table 1, the DPF value of yarn Y4 in the middle connecting layer P2 of Example 1 is twice that of Example 1. Compared with Example 5, the warp recovery of Example 1 is enhanced by 2%, the weft recovery is enhanced by 3%, and the compression recovery performance is enhanced by 25%.

[0088] 5. According to the experimental results of Example 1 and Example 6 in Table 1, the thickness of the spandex Y3 in the intermediate connecting layer P2 of Example 1 is twice that of Example 1, and the warp recovery of Example 6 is enhanced by 2% and the weft recovery is enhanced by 1% relative to Example 1, and the compression recovery performance is enhanced by 23.08%.

[0089] In summary, the spandex content of the intermediate connecting layer and the material rigidity of the yarn Y4 can enhance the warp and weft recovery, and the compression recovery performance is enhanced by the material properties of the yarn Y4 and the size of the DPF number. When the yarn Y3 is added to the intermediate connecting layer P2 based on the yarn Y4, and the spandex content of the intermediate connecting layer P2 is controlled by the yarn Y3, the compression recovery performance is mainly enhanced.

[0090] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
