Problems solved by technology

However, some of these treatment methods are costly and poor in feasibility;
[0004] Another example is a textile and its production method disclosed in Chinese patent CN201010220517.3, which uses benzyl alcohol to process nylon fabrics to improve the hygroscopic performance, but benzyl alcohol is a benzene derivative with certain toxicity, and waste liquid treatment is relatively difficult; And when this method is processed and then dyed, there are problems in color rendering

Embodiment 1

[0050] The three 47D-34f-Ny6 DTYs obtained by the conventional drafting and false twisting process are woven together on a 24G tube knitting machine, with a horizontal density of 28w*c / inch and a longitudinal density of 46w*c / inch, and the difference in moisture absorption rate △MR is 2.31 Tubular knitting, and then the obtained tube knitting is subjected to scouring-alkali treatment to obtain the polyamide fiber knitted fabric of the present invention, wherein scouring: scouring agent 2g / l, the treatment temperature is 70 ° C; alkali treatment: sodium carbonate, the concentration is 2g / l, the treatment temperature is 60°C, and the treatment time is 20min. Then the obtained knitted fabric was dyed and finished to obtain the product. Dyeing: reactive acid dye (manufactured by Huntsman Co.), the dosage was 1%; finishing: softening water-absorbing agent 4g / l, setting temperature was 170°C.

Embodiment 2

[0053] The 20D-20f-Ny6 DTY obtained by the conventional drafting and false twisting process is used as the warp and weft yarns, and the plain weave is used to weave on the air-jet loom. The horizontal density is 38w*c / inch, and the vertical density is 36w*c / inch. Ratio difference ΔMR is the woven gray cloth of 2.51, then the woven gray cloth obtained above is subjected to scouring-alkali treatment to obtain the polyamide fiber woven fabric of the present invention. Scouring: scouring agent 2g / l, treatment temperature 70°C; alkali treatment: sodium carbonate, concentration 4g / l, treatment temperature 80°C, treatment time 20min.

[0054] Compared with the product without alkali treatment, the moisture absorption difference of the obtained woven fabric is increased by 27%; compared with before washing, the moisture absorption difference retention rate after washing for 30 times is about 91%. The properties are shown in Table 1.

Embodiment 3

[0056] The 70D-24f-Ny66 DTY and 76D-96f-CD PET DTY obtained by the conventional drawing and false twisting process are interwoven at intervals one at a time, with a transverse density of 36w*c / inch and a longitudinal density of 50w*c / inch to obtain a hygroscopic Moisture rate difference ΔMR is 1.94 circular knitted fabric, and then obtained circular knitted fabric is subjected to scouring-alkali treatment to obtain the polyamide fiber knitted fabric of the present invention, and its moisture absorption rate difference ΔMR is 2.34. Scouring: scouring agent 2g / l, treatment temperature 70°C; alkali treatment: sodium carbonate, concentration 4g / l, treatment temperature 80°C, treatment time 20min. Then the gained knitted fabric is dyed and finished to obtain the product, and its moisture absorption difference △MR is 2.3 Dyeing: reactive acid dye (manufactured by Huntsman), consumption 3%; finishing: soft water absorbing agent 4g / l, setting temperature is 170°C.

Abstract

The invention discloses hygroscopic polyamide fiber textile and a production method thereof. The textile is woven fabric or knitted fabric with 20 to 100 weight % of polyamide fibers, has 2 to 6% of hygroscopicity percent difference, and 3 to 2% of washing size change rate in warp and weft directions, and the polyamide fiber has 30 to 70% of crystallinity. The production method of the hygroscopic polyamide fiber textile is simple, feasible and environment-friendly, and the textile has high hygroscopicity, can quickly and naturally discharge the moisture, produces no sense of stuffiness, is highly durable, and improves the dressing comfort.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to post-finishing processing for improving the hygroscopic performance of polyamide. Background technique [0002] People's requirements for textiles are getting higher and higher in response to the improvement of living standards. In recent years, polyamide (nylon) fiber has a broad market prospect in the field of sportswear and underwear due to its good moisture absorption function, good hand feeling and comfortable wearing. The moisture regain of polyamide 6 and polyamide 66 under standard conditions is 4.5%, second only to vinylon in synthetic fibers, but compared with natural fibers such as cotton, there is still a big gap in moisture absorption performance. [0003] Chinese patent CN200810120007.1 discloses a polyamide fiber with high hygroscopicity and its preparation method. After mixing water-soluble modified polymer resin and polyamide 6 into slices, spinning is carrie...
