Problems solved by technology

[0006] The prior art has the following technical problems in the dyeing and finishing of cupro viscose acetic acid interwoven fabrics: one is that the acid and alkali resistance of the three kinds of cupro viscose acetic acid fibers are inconsistent, cupro viscose has good alkali resistance, while acetate fiber is alkali resistant poor sex
Conventional pretreatment is done in an alkaline bath, if the acetate fiber is treated in an alkaline bath, its strength will be damaged
The second is that the dimensional stability of cupro ammonia viscose acetate fiber is poor, especially when there is tension in the open width, the dimensional shrinkage is relatively large, and it is difficult to control it within the national standard range

Abstract

The invention discloses a cuprammonium-viscose-acetate fiber fabric and a dyeing process thereof, and belongs to the technical field of fabric dyeing. The cuprammonium-viscose-acetate fiber fabric is characterized by being formed by interweaving three fibers comprising cuprammonium, viscose and acetate fiber. The dyeing process comprises the following steps: primary washing-pretreatment-secondary washing-acetate dyeing-tertiary washing-cuprammonium and viscose dyeing-quaternary washing-acid pickling to adjust the pH value and discharging from vat-primary drying-primary sizing-softening finish-secondary drying-secondary sizing, wherein the pretreatment is treatment with mild neutral treating fluid. According to the invention, the cuprammonium-viscose-acetate fiber fabric integrates the advantages of three fibers comprising cuprammonium, viscose and acetate fiber; the dyeing process realizes the dyeing of three fibers with different properties, is suitable for any proportion in the presence of three fibers comprising cuprammonium, viscose and acetate fiber, and ensures that the fabric has low shrinkage, and higher color fastness and strength, so as to have better wearability.

Description

technical field [0001] The invention relates to a dyeing and finishing process of cuproammonia viscose acetate fiber fabric, which belongs to the technical field of fabric dyeing. Background technique [0002] Cupro fiber has four functions: breathing, refreshing, antistatic, and good drapability. Its most attractive feature is that it has moisture absorption and moisture release properties, and it is a breathing and refreshing fiber. Its products are easy to wear, their performance is similar to that of real silk, and they have a great drape feeling. Coupled with its good antistatic function, it is still in an irreplaceable position. [0003] Viscose fiber is one of the earliest chemical fibers put into industrial production. Because of its good hygroscopicity, comfortable wearing and excellent spinnability, it is often blended and interwoven with cotton, wool or various synthetic fibers. The moisture content of viscose fiber is most in line with the physiological requir...
