Modified cotton fiber as well as denim-effect fabric and preparation method thereof

Abstract

The invention discloses modified cotton fiber as well as denim-effect fabric and a preparation method thereof. The preparation method of the denim-effect fabric comprises the following steps: mixing the modified cotton fiber and other fibers in a mass ratio of (1-99): (99-1), spinning into yarns, weaving to cloth, and finally dyeing and finishing to obtain the denim-effect fabric, wherein salt is not added in the dyeing and finishing process. A treatment of the modified cotton fiber comprises the following steps: blending the cotton fiber with a cationic modifier solution, heating up to 20-80 DEG C, and dipping for 1-30 minutes, wherein the cationic modifier solution to the cotton fiber is (0.01-0.1):1. By the preparation method, the mixed-color pattered denim-effect fabric can be dyed out at a time, the delivery deadline of the denim-effect fabric is shortened, the use of dye and auxiliary agents is reduced, the water washing and soaping frequency is reduced, and energy is saved and emission is reduced; an environment-friendly and functional fiber blended product also has the advantages of fashion, science and technology and high added product value.

Description

Technical field

[0001] The invention relates to the technical field of textile printing and dyeing, in particular to a modified cotton fiber, denim effect cloth and a preparation method thereof. Background technique

[0002] In the prior art, the denim effect fabric is first dyed with indigo dye on the warp yarns. After indigo dyeing, no oxidizing agent is used, but natural oxidation is adopted through ventilation. Because indigo has the characteristics of being easy to reduce and not easy to oxidize, it needs to be repeatedly dyed and oxidized many times, and the process is cumbersome. Long; after the garment is made, it needs to be washed, rubbed, and sanded with volcanic stone, sodium hypochlorite, and acid to obtain antique and old effects such as stone scrubbing and snowflake washing. The dyeing and stone grinding process takes a long time, and a large amount of dyes and auxiliaries are discharged with the water, polluting the environment, and the color fastness is not good ...
