Embodiment 1

[0032] A processing method of pure cotton 60S / 2 gray color spinning yarn, comprising the following processing steps:

[0033] 1. Anti-dyeing fiber treatment: put cotton fiber into a round cage, soak it, and press it tightly. Gum Arabic and gelatin, in the treatment solution, the concentration of microcapsules is 20g / L, the concentration of binder BN-35 (Jiahe Chemical Industry) is 10g / L, the treatment temperature is room temperature, the time is 5min, and drying after treatment.

[0034] 2. Treatment of fibers to be dyed: Natural-colored cotton fibers are treated with scouring enzymes to improve hair effect and dyeing uniformity. The process is: scouring enzyme NP (Novozymes, Denmark) in the treatment solution: 5g / L, pH value: 9. Treatment temperature: 60°C, treatment time: 30 minutes.

[0035] 3. Spinning: 80wt% scouring enzyme-treated natural cotton fiber and 20wt% microcapsule-treated fiber are blended and spun, and 60S / 2 yarn is spun through blending, roving, spun yarn, w...

Embodiment 2

[0039] A processing method of polyester-cotton 40S / 1 brown yarn, comprising the following processing steps:

[0040] 1. Anti-dyeing fiber treatment: put cotton fiber into a round cage, soak it, and press it tightly. The capsule concentration is 30g / L, the treatment temperature is 40°C, the treatment time is 60min, the binder BN-35 (Jiahe Chemical) concentration is 80g / L, and dried after treatment.

[0041]2. Treatment of fibers to be dyed: Natural-colored cotton fibers are treated with scouring enzymes to improve hair effect and dyeing uniformity. The process is: scouring enzyme NP (Novozymes, Denmark) in the treatment solution: 3g / L, pH value: 7. Treatment temperature: 45°C, treatment time: 15 minutes.

[0042] 3. Spinning: 30wt% scouring enzyme-treated natural cotton fiber, 35wt% polyester staple fiber and 35wt% microcapsule treated fiber are blended and spun, and spun through blending, roving, spun yarn, winding and other processes Made into 40S / 1.

[0043] 4. Dyeing: Dy...

Embodiment 3

[0046] A processing method of cotton / flax 32S / 1 black color yarn, comprising the following processing steps:

[0047] 1. Anti-dyeing fiber treatment: put the flax fiber into a round cage, soak it and compact it, add the microcapsule treatment solution, the core material of the microcapsule is sodium hypochlorite, the wall material is gum arabic and gelatin, and the concentration of the microcapsule is 60g / L, the treatment temperature is 80°C room temperature, the time is 40min, the concentration of the binder BN-35 (Jiahe Chemical Industry) is 40g / L, and it is dried.

[0048] 2. Pre-treatment of fibers to be dyed: Treat natural-colored cotton fibers with scouring enzymes to improve capillary effect and dyeing uniformity. The process is: scouring enzyme NP (Novozymes, Denmark) in the treatment solution: 4g / L, pH value : 8, treatment temperature: 50° C., treatment time: 20 minutes.

[0049] 3. Spinning: 60wt% natural cotton fiber treated with scouring enzyme and 40wt% flax fib...

Abstract

The invention discloses color-spun yarns, which are obtained by mixing and dyeing dye-resistant fibers and fibers to be dyed into yarns. The color-spun yarns are prepared by the following steps of a, treating dye-resistant fibers: treating the fibers with microcapsules and a bonding agent and drying to obtain the dye-resistant fibers, wherein dye-retarding agents or dye-resistant agents are coated in the microcapsules; b, spinning: mixing fibers to be dyed with the dye-resistant fibers obtained in the step a and spinning to obtain yarns; c, dyeing: dyeing the yarns obtained in the step b with a dye; d, washing the yarns dyed in the step C with water and drying to obtain color-spun yarns. The colors of the color-spun yarns can be dyed in a customized mode, the delivery period is less than one week, and the problems of reduction in the spinning efficiency, increase in unattached fibers, rise of direct cost, great reduction in the strength of finished yarns, incapability of spinning high-count yarns and the like caused by the increase of chopped fiber rate due to dyeing pretreatment of the conventional color-spun yarns are solved.

Description

Technical field [0001] The present invention involves the field of textile technology, and is a color spinning yarn produced by a new type of process. Specifically, it is a new type of color spinning gauze that gives fiber treatment to the resistance to staining, and then the spinning and dyeing.Wire. Background technique [0002] The existing color spinning is first dyed the fiber to a color fiber, and then the fibers of two or more different colors are mixed after being fully mixed, and the spinning is textured into a yarn with a unique mixed -color effect.However, because the colorful spinning needs to be cooked by a strong oxidant or a reducing agent during the fiber dyeing stage, dyeing and post -treatment in alkaline and high temperature environments, and the mechanical processes such as artificial steps, gauze, and cage can cause fiber to cause fiber to cause fiberFor severe damage, the length of the fiber will become shorter, the feel feels harder, and the short fiber rat...
