Embodiment 1

[0033] (1) Double-sided rib fabric is selected, with a weight of 480kg and a weight of 175g / m 2 , door width: 160cm, the quality of each piece of cloth is 15kg / piece, woven from 40S modal and polyester blended yarn, and the blending ratio of modal and polyester is 60 / 40.

[0034] (2) Put the double-sided rib fabric into a dye vat containing 1.5% sulfuric acid solution at room temperature, raise the temperature to 110°C at 1.5°C / min, and keep it warm for 60min. After the holding time is completed, cool down at 1.5°C / min to 50°C, neutralize the acidity in the vat with 2g / L soda ash, and check the pH of the cloth surface after the water is completely drained, and start dyeing when the pH is 5-7.

[0035] Measure the weight loss rate: bring in a 10g cloth strip when opening the fiber, take out the cloth strip after the fiber opening is completed, weigh it after drying, and calculate the weight loss rate by (10-the weight after opening the fiber) / 10*100%. The weight loss rate of t...

Embodiment 2

[0045] Referring to Example 1 for process treatment, only the blending ratio of modal and polyester was changed to 50 / 50, and the weight loss rate of the double-sided rib fabric was measured to be 7.5%. In this embodiment, the imitation cupro fiber fabric also has the luster, softness, velvet feeling and drape feeling similar to that of the cupro fiber fabric.

[0046] Acid resistance test: Take 180 grams of cupro-like fabric and treat it in 1wt% sulfuric acid solution at 60°C for 30 minutes. After drying, the measured strength is 230N.

[0047] Alkali resistance test: Take 180 grams of cupro-like fabric and treat it in 1wt% sodium hydroxide solution at 60°C for 30 minutes. After drying, the measured strength is 255N.

[0048] Wet strength test: After taking 180 grams of cupro-like fabric and soaking it evenly with water, the measured wet strength is 190N.

Embodiment 3

[0050] Referring to Example 1 for process treatment, only the single-side rib fabric was selected, and the weight loss rate of the single-side rib fabric was measured to be 8.9%. This embodiment can also obtain the imitation cupro fiber fabric, which has the luster, soft feeling, velvet feeling and drape feeling similar to the cupro ammonia fiber fabric.

[0051] Acid resistance test: Take 180 grams of cupro-like fabric and treat it in 1wt% sulfuric acid solution at 60°C for 30 minutes. After drying, the measured strength is 232N.

[0052] Alkali resistance test: Take 180 grams of cupro-like fabric and treat it in 1wt% sodium hydroxide solution at 60°C for 30 minutes. After drying, the measured strength is 251N.

[0053] Wet strength test: After taking 180 grams of cupro-like fabric and soaking it evenly with water, the measured wet strength is 197N.

Abstract

The invention relates to a treatment technology of copper ammonia fiber imitating shell fabric. The treatment technology comprises the following steps that (1) a gray fabric is subjected to splittingtreatment by adopting sulfuric acid, and the weight loss ratio of the gray fabric is controlled to be 6-10%; the gray fabric is formed through weaving of yarns blended by polyester fiber and modal fiber, wherein the blending ratio of modal fiber to polyester fiber is (50 to 50)-(70 to 30); (2) the cloth cover pH value of the gray fabric which is subjected to splitting treatment is controlled to be5-7, the gray fabric is subjected to dyeing treatment, and the gray fabric is dried; and (3) the dyed gray fabric is subjected to sand washing, and circular drying, and the copper ammonia fiber imitating shell fabric is obtained. The treatment technology makes the shell fabric woven by yarns formed through blending of polyester and modal fiber have the gloss, the soft feeling, the fluffy feelingand the overhang feeling possessed by the shell fabric similar to copper ammonia fiber shell fabric by improving the shell fabric technology, and the wearability of the shell fabric is better and morecomfortable.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a treatment process for imitation copper ammonia fiber fabrics. Background technique [0002] Cupro ammonia fiber is a kind of regenerated cellulose fiber. Its preparation process is to dissolve natural cellulose raw materials such as cotton linters in a concentrated ammonia solution of copper hydroxide or alkaline copper salt to prepare a spinning solution; After soaking, solidify and form in the spinning bath of water or light alkali solution; then decompose the molecular compound of cupro ammonia fiber in the second bath liquid containing 2-3wt% sulfuric acid solution to regenerate cellulose; the generated water and The cellulose fibers are washed with water, and then treated with dilute acid solution to remove copper residues, washed, oiled, and dried. [0003] The cross-section of cupro ammonia fiber is round and has no skin-core structure. The fabric produced is soft to the touch, ...
