Problems solved by technology

However, once the cotton fiber reaches the saturated state after absorbing sweat, the drying speed is slow, and it takes a long time from the wet state to the water balance.

Embodiment 1

[0037] Such as figure 1 , 3 As shown, this embodiment provides a dyeing and finishing process for polyester-covered cotton unidirectional moisture-wicking knitted fabrics. The specific process flow is: weaving fabric→single-dyed polyester→hair removal enzyme finishing→hydrophilic finishing→cotton surface water-repellent finishing→ Baking, wherein the water-repellent finishing of the cotton face includes dehydration, drying, printing and post-drying in sequence of processes.

[0038] In this embodiment, the polyester face of the polyester-covered cotton knitted fabric is made of moisture-absorbing and sweat-wicking polyester, and the next-to-body cotton face is made of pure cotton yarn. W"-shaped fibers and other special-shaped cross-section fibers, because there are grooves on the surface of the special-shaped cross-section fibers, the longitudinal small gaps between the fibers increase, the capillary effect is enhanced, and the speed of sweat wetting is beneficial to increas...

Embodiment 2

[0052] Such as figure 2 , 4 As shown, this embodiment provides a dyeing and finishing process for polyester-covered cotton unidirectional moisture-wicking knitted fabrics. The specific process flow is: weaving fabric→single-dyed polyester→hair removal enzyme finishing→cotton surface water-repellent finishing→hydrophilic finishing→ Baking, wherein the water-repellent finishing of the cotton face includes dehydration, drying, printing and post-drying in sequence of processes.

[0053] In this embodiment, the polyester face of the polyester-covered cotton knitted fabric is made of moisture-absorbing and sweat-wicking polyester, and the next-to-body cotton face is made of pure cotton yarn.

Abstract

The invention relates to a dyeing and finishing process for a cotton-plaited polyester one-way wet-permeable knitted fabric. The dyeing and finishing process for the cotton-plaited polyester one-way wet-permeable knitted fabric comprises the following specific steps: after only dyeing polyester of a cotton-plaited polyester knitted fabric in a dyeing machine, finishing the cotton-plaited polyesterknitted fabric by hair removal enzyme; and after finishing the cotton-plaited polyester knitted fabric by the hair removal enzyme, separately carrying out hydrophilic finishing and cotton surface water repellent finishing. The fabric has a one-way wet-permeable function, when a user takes strenuous exercises, sweat can rapidly permeate to the outside from the inner layer, thus, dryness and comfortableness of skin are maintained, bacteria are prevented from being bred, the fabric wears comfortably, and is suitable to be used as a fabric for autumn and winter sportswear or a fabric for school uniforms, moreover, dyeing defects such as polyester complexion, color spots, barriness and chicken claw grains can be avoided, dyeing difficulty is reduced, the dyeing effect tis improved, the dyeingquality is improved, dyeing is uniform, the function lasts for a long time, and the circumstance that color cannot be weaken sharply and even disappears along with increasing of washing times is avoided.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing of knitted fabrics, in particular to a dyeing and finishing process of polyester-cotton unidirectional moisture-wicking knitted fabrics. Background technique [0002] The unidirectional moisture-wicking fabric transfers sweat from the skin to the atmosphere through the differential capillary effect or the wetting gradient effect; and the sweat does not diffuse in the inner layer of the fabric, which can keep the human skin dry. Unidirectional moisture-wicking fabrics usually construct hydrophilic and hydrophobic regions on the front and back of double-sided fabrics. It often uses polyester and polypropylene for interweaving, and uses the water-repellent effect of polypropylene and the quick-drying characteristics of polyester to transfer sweat to the outside of the body and quickly evaporates; water while the other side is hydrophobic. However, the cost of unidirectional moisture-wi...
