Problems solved by technology

However, with the increase of the number of times of sanding and the increase of vertical stretching, the probability of flower stains also increases. Only through the shaker machine to soften the air and shake the fabric to suck out the hair
Increase the stretching and empty soft processes, resulting in a significant increase in the processing cost of the finished product

Embodiment

[0035] Improved process flow: material preparation→dyeing→drying→sanding 2 times→stentering→pre-shrinking→rolling finished product.

[0036] Dyeing process: including pretreatment, pickling, dyeing and post-treatment, refer to the attached figure 2 Details of the dyeing process. Reactive dyes: navy blue: 2.65%, red: 1.75%, yellow: 1.6%; Na 2 SO 4 :90%, Na 2 CO 3 : 30%, leveling agent: 1%.

[0037] Soaping uses alcohol ether surfactant as fatty alcohol polyoxyethylene ether, molecular formula C 12 h 25 O·(C 2 h 4 O) n, n=15~20, use concentration is 1%.

[0038] Drying process: refer to Table 1 for comparative examples.

[0039] Sanding process: The Lafer sanding machine used in the sanding process uses carbon rollers to grind out the microfibers in the fabric yarn, and sands them continuously for 2 times to form a fluffy effect on the surface. For sanding parameters, refer to Comparative Table 3 .

[0040] After dyeing, adding alcohol-based surfactants in the soapi...

Abstract

The invention belongs to the technical field of dyeing and finishing technology. In order to eliminate static electricity on the surface of the fabric in the carbon sanding process of the existing fabric, a tentering process of an anti-static auxiliary needs to be added. However, the anti-static auxiliary will make the fabric feel soft. In order to achieve the same sanding effect, the tension of the sanding and the time for sanding are needed to increase, which will increase the probability of contamination of the variegated wool. Therefore, it is necessary to add an air-softening and hair-removing process of an anti-pilling machine, which significantly increases processing cost. In view of the above problems, the invention provides a method for improving surface electrostatic properties of carbon sanded fabrics. Alcohol-ether surfactants are added during the soaping process of the fabric after dyeing, the tentering process of the anti-static auxiliary before the sanding and the air-softening and hair-removing process after the sanding are eliminated, and the time of sanding is reduced at the same time. The method reduces the electrostatic effect of the fabric without increasing washing, and reduces the processing cost.

Description

technical field [0001] The invention belongs to the technical field of fabric dyeing and finishing, and in particular relates to a method for improving surface static electricity of carbon brushed fabrics. Background technique [0002] The generation of static electricity is generally due to friction. If it is an insulating material, the static electricity generated by friction cannot be dissipated, and it will gather on the surface of the fabric, resulting in a relatively obvious static electricity phenomenon. When the pure cotton fabric is sanded, due to the rapid operation and tension of the carbon roller of the sanding machine, a complex and unstable electric field is formed in the space where the fabric and carbon fibers rub against each other. The fiber scum that falls off the surface of the fabric through high-speed friction with high-strength carbon fibers can be sucked out by the vacuum fan in a complex and disordered field, but some of it cannot be sucked out due t...
