Problems solved by technology

[0002] In the prior art, the denim effect fabric is firstly dyed with indigo dye on the warp yarn. After indigo dyeing, no oxidant is used, but natural oxidation is adopted through ventilation. Since indigo is easy to restore and not easy to oxidize, it needs to be repeatedly dyed and oxidized, and the process is cumbersome and time-consuming. 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-fashioned effects such as stone grinding, snow washing, etc.
The dyeing and stone grinding process takes a long time, and a large amount of dyes and auxiliaries are discharged with water, polluting the environment, and the color fastness of the indigo dye is not good

Embodiment 1

[0028] Choose 100kg cotton, add 5kg quaternary ammonium cationic modifier after smelting, heat up to 60℃ and soak for 30 minutes, add colorant too soft (the colorant is non-reactive dye or pigment, used as temporary coloring For marking, the colored cationic modified cotton fiber can be removed in the pre-treatment process of yarn or cloth scouring) to obtain modified cotton fiber. 50% modified cotton fiber and 50% raw cotton are mixed and spun in AB yarn style to weave white plain weave cloth. The cloth swatches should be dyed with ordinary blue reactive dye BRF. No salt is added in the dyeing bath, and the amount of soda ash is 10 g / l. The cloth swatch with blue denim effect can be obtained.

Embodiment 2

[0030] Choose 100kg cotton, add 8kg quaternary ammonium cationic modifier after scouring, heat up to 50°C and immerse for 25 minutes, then add coloring agent to make modified cotton fiber. Combine 40% modified cotton fiber, 50% bleached cotton and 10% other fibers (as required: raw cotton, bleached cotton, mercerized cotton, regenerated cellulose fiber, protein fiber, white bamboo charcoal fiber, polyester, acrylic, Amicor antibacterial fiber , Seaweed fiber or Outlast fiber) mixed and spun in a segment color style, woven into a white plain weave cloth. The cloth swatches should be dyed with ordinary royal blue reactive dyes. No salt is added in the dyeing bath, and the amount of soda ash is 10 g / l to obtain a dark blue denim effect cloth swatch.

Embodiment 3

[0032] 100kg cotton is selected, after bleaching, 6kg of quaternary ammonium cationic modifier is added, the temperature is raised to 65°C and immersed for 20 minutes, and the coloring agent is added over soft to obtain modified cotton fiber. Mix 50% modified cotton fiber, 40% bleached cotton and 10% other fibers and spun in a slub style to woven white plain weave. The cloth swatches should be dyed with ordinary royal blue reactive dyes. No salt is added in the dyeing bath, and the amount of soda ash is 10 g / l to obtain a dark blue denim effect cloth swatch.

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 ...
