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] Select 100kg cotton, after simmering, add 5kg of quaternary ammonium cationic modifier, raise the temperature to 60°C and soak for 30 minutes, then add coloring agent (the coloring agent is a non-reactive dye or pigment, as a temporary coloring agent) Used for marking, the colored cationic modified cotton fiber can be removed during the pre-scouring process of yarn or cloth) to obtain modified cotton fiber. 50% modified cotton fiber and 50% raw cotton are mixed and spun in AB yarn style, and woven into white plain weave. The cloth sample should be dyed with common blue reactive dye BRF, no salt is added in the dyeing bath, the dosage of soda ash is 10 g / liter, and blue denim effect cloth sample can be obtained.

Embodiment 2

[0030] Select 100kg cotton, after scouring, add 8kg of quaternary ammonium cationic modifier, raise the temperature to 50°C and soak for 25 minutes, then add coloring agent after softening, to obtain modified cotton fiber. 40% modified cotton fiber, 50% bleached cotton and 10% other fibers (optional: raw cotton, bleached cotton, mercerized cotton, regenerated cellulose fiber, protein fiber, white bamboo charcoal fiber, polyester, acrylic fiber, Amicor antibacterial fiber , seaweed fiber or Outlast fiber) mixed and spun in a segmented color style, and woven into white plain weave. The cloth sample should be dyed with ordinary royal blue reactive dye, no salt is added in the dyeing bath, and the dosage of soda ash is 10 g / liter, and the dark blue denim effect cloth sample can be obtained.

Embodiment 3

[0032] Select 100kg cotton, after bleaching, add 6kg of quaternary ammonium cationic modifier, raise the temperature to 65°C and soak for 20 minutes, then add coloring agent after softening, to obtain modified cotton fiber. 50% modified cotton fiber, 40% bleached cotton, and 10% other fibers are mixed and spun in a slub style, and woven into a white plain weave. The cloth sample should be dyed with ordinary royal blue reactive dye, no salt is added in the dyeing bath, and the dosage of soda ash is 10 g / liter, and the dark blue denim effect cloth sample can be obtained.

Abstract

The invention discloses a modified cotton fiber, a denim effect cloth and a preparation method thereof. The preparation method of the denim effect cloth comprises the following steps: mixing the modified cotton fiber and other fibers at a mass ratio of 1‑99:99‑1, Spin into yarn, then weave into cloth, and finally carry out dyeing and finishing. In the dyeing and finishing process, no salt is added to obtain the denim effect cloth; the treatment method of the modified cotton fiber is: the cotton fiber is modified with cationic The mixture is mixed with the cationic modifier solution, heated to 20-80°C, and soaked for 1-30min. The mass ratio of the cationic modifier to the cotton fiber is 0.01-0.1:1. By using the method of the invention, the mixed-color fancy denim effect can be dyed at one time, the product delivery period is shortened, the use of dyes and auxiliary agents is reduced, the times of washing and soaping are reduced, and energy saving and emission reduction are achieved. The blended fabric of this environment-friendly and functional fiber also has the advantages of fashion, technology and high added value of the product.

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 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 reduce 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 and snow washing. The dyeing and stone milling process takes a long time, and a large amount of dyes and auxiliaries are discharged with water, which pollutes the environment, and the color fastness of the indigo dye is not good.
