The present application relates to the technical field of textile materials, and particularly relates to a kind of micro-porous moisture absorption and sweat releasing quick-drying yarn and its preparation method and fabric, comprising the following steps: S1, preparation, polyamide chip is prepared by using reaction monomer, water-soluble monomer and dispersed monomer in-situ polymerization and slicing;S2, polyamide filament with special cross section is obtained by spinning and winding with polyamide chip as raw material;S3, leaflet open hole polyamide filament is obtained by alkali treatment in the state of skein;S4, leaflet open hole polyamide filament is processed into polyamide staple fiber, and core yarn is obtained by wrapping polyamide staple fiber around Coolmax filament to obtain core-spun yarn.The present application realizes alkali-soluble polyamide and realizes the communication of opening and groove by changing monomer and skein alkali treatment, and can quickly absorb moisture, diffuse and transfer, and evaporate to dry quickly;The technical defects that the inherent gap between the existing staple yarn cannot quickly guide moisture and release sweat are solved, and the moisture and sweat releasing performance of the yarn is further improved.

The invention discloses a waterproof, moisture-absorbing and sweat-releasing fabric and a preparation method thereof. The fabric comprises an inner layer, an outer layer and a middle layer, the inner layer is made of Tencel fiber and spandex fiber blended yarn; the outer layer is made of fluoride-free waterproof yarn and polyester fiber blended yarn; the middle layer is formed by connecting Coolmax fiber yarns between the inner layer and the outer layer in a tucking or floating thread manner to form a discontinuous middle air layer; the preparation method comprises the following steps: respectively dyeing and pre-treating the blended yarns and the fiber yarns; dipping cotton yarns in the fluoride-free waterproof finishing liquid, and baking to obtain waterproof yarns; weaving double-layer grey cloth at one time by adopting a double-sided circular knitting machine; and finally, carrying out mild after-treatment. The waterproof barrier is constructed in the yarn stage, so that the fabric has lasting waterproofness, efficient moisture absorption and sweat releasing performance and excellent air permeability, and the preparation process effectively protects the durability of the waterproof function.

The invention relates to a double-layer polyester cotton knitted fabric with moisture absorption and sweat releasing performance, which comprises a moisture absorption layer and a moisture absorption and sweat releasing layer, and the moisture absorption layer and the moisture absorption and sweat releasing layer are woven into a whole by weft knitting double-layer tissues; a minimum circulation unit of the weft knitting double-layer weave comprises twelve loop-forming systems, the first loop-forming system, the third loop-forming system, the fifth loop-forming system, the seventh loop-forming system, the ninth loop-forming system and the eleventh loop-forming system form a moisture absorption layer through weaving, the second loop-forming system, the fourth loop-forming system, the sixth loop-forming system, the eighth loop-forming system, the tenth loop-forming system and the twelfth loop-forming system form a moisture absorption and sweat releasing layer through weaving, and hydrophobic cotton yarn is fed into the first loop-forming system and the seventh loop-forming system for weaving. Composite yarn is fed into the third-path looping system, the fifth-path looping system, the ninth-path looping system and the eleventh-path looping system for weaving, the composite yarn comprises a COOLMAX filament and a pure cotton yarn, and the COOLMAX filament and the pure cotton yarn are spirally wound with each other; moisture absorption and sweat releasing filaments are fed into the second loop forming system, the fourth loop forming system, the sixth loop forming system, the eighth loop forming system, the tenth loop forming system and the twelfth loop forming system for weaving, the skin layers of the moisture absorption and sweat releasing filaments are lithium chloride modified EVOH, the core layers of the moisture absorption and sweat releasing filaments are composite fibers of skin-core structures of hydrophilic polyester, and a plurality of micropores are distributed in the surfaces of the hydrophilic polyester; the fabric is skin-friendly, comfortable and good in moisture absorption and sweat releasing performance.

This invention discloses a phase change polyester intelligent temperature-regulating multifunctional knitted fabric and its manufacturing method, belonging to the field of weaving and dyeing technology. It is made of a blend of phase change polyester fiber, Coolmax freshFX fiber, and Antares fiber. The phase change polyester intelligent temperature-regulating multifunctional knitted fabric is a double-layer fabric. Coolmax freshFX fiber and phase change polyester fiber are used for the skin-contact layer of the fabric, while Antares fiber is used for the outer layer. The phase change polyester fiber includes a core layer and a sheath layer wrapped around the surface of the core layer. The sheath layer includes polyester fiber and high thermal conductivity powder, while the core layer includes a phase change temperature-regulating material and low melting point polyester. The manufacturing method includes the following steps performed sequentially: weaving, fabric preparation, pre-dyeing treatment, disperse dye dyeing, reduction washing, reactive dye dyeing, drying, and setting. This fabric can retain the temperature-regulating function of the phase change fiber to the greatest extent after washing and also has antibacterial and moisture-wicking quick-drying properties.
