[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] A breathable stretch fabric comprises: a base fabric layer, wherein the base fabric layer is woven by three comb bars GB1, GB2 and GB3. Figure 4As shown, GB1 adopts the first composite yarn, the structure is 3-2 / 2-1 / 4-5 / 3-2 / 1-0 / 3-4 / / , and the threading rule is one threading and one emptying.

[0023] like Figure 5 As shown, GB2 uses the second composite yarn, the structure is 2-3 / 3-4 / 1-0 / 2-3 / 4-5 / 2-1 / / , and the threading rule is one threading and one emptying.

[0024] like Figure 6 As shown, GB3 adopts the third composite yarn, the structure is 4-5 / 1-0 / 4-5 / 1-0 / 4-5 / 1-0 / / , and the threading rule is full threading.

[0025] like Figure 1 As shown, the first composite yarn includes a core yarn and a wrapping yarn spirally wound around the core yarn, the core yarn is a cotton-spandex core-spun yarn, the wrapping yarn includes aramid filaments 11 and polylactic acid filaments 12, and the aramid filaments 11 and polylactic acid filaments 12 are spirally wound around the outside of the cotton-spandex core-spun yarn in a 1:1 arrangement ratio. The core yarn of the cotton-spandex core-spun yarn is spandex filaments 13, and the wrapping yarn is cotton fiber yarn 14.

[0026] Cotton-spandex core-spun yarn can improve the elasticity and breathability of fabrics. Polylactic acid filament 12 has the characteristics of wrinkle resistance and resilience, soft hand feeling, antibacterial and non-irritating, etc., which can improve the deformation and antibacterial ability of fabrics and improve the hand feeling of fabrics. Aramid filament 11 has extremely high modulus and strength, which can greatly improve the tear resistance and wear resistance of fabrics, and is conducive to extending the life of fabrics.

[0027] Preferably, the cotton fiber yarn 14 is an antibacterial cotton fiber yarn to improve the antibacterial ability of the fabric. The fineness of the polylactic acid filaments 12 is greater than that of the aramid filaments 11, so that the part of the first composite yarn that contacts the human body is the polylactic acid filaments 12, reducing the impact of aramid on the touch of the fabric.

[0028] like Figure 2 As shown, the second composite yarn is formed by twisting two memory fiber yarns 15 and two cotton-spandex core-spun yarns. The memory fiber yarn 15 and the cotton-spandex core-spun yarn are arranged alternately, and the fineness of the cotton-spandex core-spun yarn is greater than the fineness of the memory fiber yarn 15. The core yarn of the cotton-spandex core-spun yarn is spandex filament 13, and the covering yarn is cotton fiber yarn, which has elasticity and moisture absorption and breathability, making the elasticity and breathability of the fabric better. The memory fiber yarn 15 has memory ability, which enables the fabric to recover after deformation, which can prevent the sports socks made of the fabric from being deformed and unusable due to strenuous exercise, and can extend the service life of the sports socks.

[0029] The memory fiber yarn 15 is thinner than the cotton-spandex core-spun yarn, so that the part of the second composite yarn in contact with the human body is cotton fiber, which feels soft and comfortable, and can improve the overall comfort of the fabric. Among them, the memory fiber yarn 15 is an oxidized carbon nanotube modified polyvinyl alcohol shape memory fiber yarn. The preparation method of oxidized carbon nanotube modified polyvinyl alcohol shape memory fiber comprises the following steps: (1) after calcination and purification, carbon nanotubes are added to a mixed solution of concentrated sulfuric acid and concentrated nitric acid, heated, stirred and ultrasonically treated, diluted, centrifuged, washed and dried to obtain oxidized carbon nanotube powder; (2) polyvinyl alcohol is added to a dimethyl sulfoxide solution, heated, stirred and dissolved to obtain a polyvinyl alcohol solution; (3) N,N'-dicyclohexylcarbodiimide and 4-dimethylaminopyridine are added to the dimethyl sulfoxide solution, stirred evenly, and the oxidized carbon nanotube powder prepared in step (1) is added and dispersed evenly to obtain an oxidized carbon nanotube solution; (4) the oxidized carbon nanotube solution prepared in step (3) is added dropwise to the polyvinyl alcohol solution prepared in step (2), stirred and reacted at room temperature, washed and filtered with methanol to remove unreacted polyvinyl alcohol, and dried to obtain oxidized carbon nanotubes modified with polyvinyl alcohol; (5 ) Add the polyvinyl alcohol modified oxidized carbon nanotubes prepared in step (4) to the polyvinyl alcohol solution prepared in step (2), stir evenly, drop glutaraldehyde crosslinking agent, heat and stir to react, stand to degas, and obtain oxidized carbon nanotube / polyvinyl alcohol spinning solution; the mass ratio of polyvinyl alcohol modified oxidized carbon nanotubes, polyvinyl alcohol solution and glutaraldehyde crosslinking agent is 1-5:100:0.5-1; (6) Place the oxidized carbon nanotube / polyvinyl alcohol spinning solution prepared in step (5) in a wet spinning device, heat and pressurize to extrude, and coagulate in a coagulation bath to obtain oxidized carbon nanotube / polyvinyl alcohol nascent fibers; (7) Attach the oxidized carbon nanotube solution prepared in step (3) to the surface of the oxidized carbon nanotube / polyvinyl alcohol nascent fibers prepared in step (6), pre-dry, place in a methanol solution to fully coagulate, and perform heat stretching and post-treatment to obtain oxidized carbon nanotube modified polyvinyl alcohol shape memory fibers.

[0030] Preferably, the cotton fiber yarn 14 is antibacterial cotton fiber yarn to improve the antibacterial ability of the fabric.

[0031] like Figure 3 As shown, the third composite yarn is a polyester-spandex core-spun yarn, the core yarn of the polyester-spandex core-spun yarn is spandex filament 13, and the covering yarn is an antibacterial polyester fiber yarn 16. The spandex filament 13 can improve the elasticity of the fabric, and the antibacterial polyester fiber yarn 16 can improve the antibacterial ability and anti-wrinkle and anti-deformation ability of the fabric.

[0032] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
