[0002] With the continuous improvement of people's environmental awareness and the pursuit of life quality, traditional textile fabrics gradually fail to meet market demand in terms of environmental performance and comfort. Traditional fabrics may use a large amount of chemical dyes and auxiliaries in the production process, not only causing environmental pollution, but also potentially harming human health. At the same time, the comfort of some fabrics, such as softness, air permeability, etc., also needs to be further improved.

[0003] Although there are some environmentally friendly fabrics on the market at present, they often have certain limitations in performance, for example, fabrics with good environmental performance may not perform well in softness, air permeability, etc., and cannot simultaneously consider environmental protection and comfort performance.

[0004] Therefore, it is of great practical significance to develop a fabric that is both super-cotton-feeling comfortable and green and environmentally friendly. SUMMARY

[0005] The technical problem to be solved by the present application is to overcome the above technical defects, and to provide a super-cotton-feeling green and environmentally friendly fabric and a production process thereof, which has a soft touch similar to cotton and good air permeability, and uses natural and degradable raw materials, is environmentally friendly in the production process, and reduces environmental pollution.

[0006] To solve the above technical problems, the technical solution provided by the present application is as follows: a super-cotton-feeling green and environmentally friendly fabric, which is interwoven by yarns composed of the following components:

[0007] regenerated cellulose fiber, natural degradable fiber, bio-based elastic fiber, and natural plant dye.

[0008] The weight ratio of each component is:

[0009] The regenerated cellulose fiber is 30-60%, the natural degradable fiber is 20-30%, the bio-based elastic fiber is 10-15%, and the natural plant dye is 0.5-2%.

[0010] Preferably, the regenerated cellulose fiber is one or a combination of viscose fiber, Tencel fiber, and Modal fiber.

[0011] Preferably, the natural degradable fiber is one or a combination of organic cotton fiber, bamboo fiber, and linen fiber.

[0012] Preferably, the bio-based elastic fiber is polylactic acid elastic fiber or bio-based polyurethane elastic fiber.

[0013] Preferably, the natural plant dye is one or more of the following natural pigments extracted from madder, indigo, turmeric and safflower.

[0014] Preferably, the fabric has a grammage of 120-300g / m 2 , an air permeability of ≥500mm / s, a softness of 5-10mN, a warp density of 80-120 ends / inch, and a weft density of 60-100 ends / inch.

[0015] The fabric surface has a micro-nano groove structure, and the fabric is obtained by biological enzyme treatment.

[0016] Another aspect of the present application discloses a production process of an ultra-cotton-like green and environmentally friendly fabric, comprising the following steps:

[0017] S1: fiber pretreatment: pretreating regenerated cellulose fibers, natural plant protein fibers and bio-based elastic fibers;

[0018] S2: blending into yarn: mixing the pretreated fibers in proportion to obtain blended yarn;

[0019] S3: dyeing: after biological enzyme treatment of the yarn, a natural plant dye is prepared into a dyeing solution with a concentration of 5-15%, 1-3% of a natural mordant is added, and the blended yarn is dyed and then subjected to fixation treatment;

[0020] S4: weaving: using an air-jet loom or a rapier loom for weaving;

[0021] S5: post-treatment: washing, drying and setting the woven fabric.

[0022] Preferably, the pretreatment in S1 includes opening, impurity removal and plasma treatment.

[0023] In S3, a composite biological enzyme is used for treatment at 40-55℃ for 30-60 minutes, with a bath ratio of 1:15-1:25, and ultrasonic-assisted dyeing is used during dyeing.

[0024] Preferably, the composite biological enzyme in S3 includes a mixture of cellulase, protease and pectinase.

[0025] Preferably, the post-treatment in S5 further includes padding treatment using an amino acid-based softener.

[0026] Compared with the prior art, the present application has the following advantages: the present application uses natural degradable fibers and bio-based elastic fibers, reducing the dependence on non-renewable resources, and the fabric can be naturally degraded after use, reducing environmental pollution.

[0027] The use of natural plant dyes avoids the use of chemical dyes, reduces wastewater discharge and environmental pollution during production.

[0028] By reasonably selecting the fiber components and optimizing the production process, the fabric has a soft touch similar to cotton, good air permeability and moisture absorption, and the micro-nano groove structure on the surface of the fabric further enhances the fabric performance, providing a more comfortable experience for the wearer.
