Problems solved by technology

(2) Although the standard moisture regain of pure wool textiles is as high as 14% (20°C, relative humidity 65%), there will also be static electricity when the relative humidity is less than 40%.
However, existing enterprises use a large number of organic silicon finishing agents with better softness for treatment, resulting in very serious static electricity.

Embodiment 1

[0027] (1) Cleaning: Wash wool textiles with 20-30℃ water to remove residual grease and dust on the wool textiles, and dehydrate the washed wool textiles with a margin rate of 60-70%;

[0028] (2) Dipping: Immerse the washed wool textiles in the anti-static finishing liquid. The temperature of the anti-static finishing liquid is maintained at 60-70℃, and the immersion time is controlled at 15 minutes. After the immersion, the wool textiles are dehydrated and rolled. The remaining rate is 60-70%;

[0029] (3) Drying: Dry the above-mentioned dipped woolen textile at 70-80°C to reduce the moisture content to below 5%;

[0030] (4) Secondary immersion: the wool textile after the above drying is immersed in the anti-static finishing solution again, the anti-static finishing solution used is adjusted to pH 4-5 by dripping 70% dilute sulfuric acid, and the temperature of the anti-static finishing solution Maintain at 70-80℃, control the immersion time at 15min, do dehydration treatment to ...

Embodiment 2

[0035] (1) Cleaning: Wash wool textiles with 20-30℃ water to remove residual grease and dust on the wool textiles, and dehydrate the washed wool textiles with a margin rate of 60-70%;

The temperature of the anti-static finishing liquid is maintained at 60-70℃, and the immersion time is controlled at 15 minutes. After the immersion, the wool textiles are dehydrated and rolled. The remaining rate is 60-70%;

[0037] (3) Drying: Dry the above-mentioned dipped woolen textile at 70-80°C to reduce the moisture content to below 5%;

[0038] (4) Secondary immersion: the wool textile after the above drying is immersed in the anti-static finishing solution again, the anti-static finishing solution used is adjusted to pH 4-5 by dripping 70% dilute sulfuric acid, and the temperature of the anti-static finishing solution Maintain at 70-80℃, control the immersion time at 15min, do dehydration treatment to ...

Embodiment 3

[0043] (1) Cleaning: Wash the wool textiles with 20-30℃ water to remove the residual grease and dust on the wool textiles, and dehydrate the washed wool textiles with a margin rate of 60-70%;

[0044] (2) Dipping: Immerse the washed wool textiles in the anti-static finishing liquid. The temperature of the anti-static finishing liquid is maintained at 60-70℃, and the immersion time is controlled at 15 minutes. After the immersion, the wool textiles are dehydrated and rolled. The remaining rate is 60-70%;

[0045] (3) Drying: Dry the above-mentioned dipped woolen textile at 70-80°C to reduce the moisture content to below 5%;

[0046] (4) Secondary immersion: the wool textile after the above drying is immersed in the anti-static finishing solution again, the anti-static finishing solution used is adjusted to pH 4-5 by dripping 70% dilute sulfuric acid, and the temperature of the anti-static finishing solution Maintain at 70-80℃, control the immersion time at 15min, do dehydration treat...

Abstract

The invention discloses an antistatic finishing technology of woolen textiles, and relates to the technical field of processing of textiles. The antistatic finishing technology comprises the followingsteps of 1, cleaning, 2, dipping, 3, drying, 4, secondary dipping and 5, secondary drying. Antistatic finishing liquid is different from common antistatic finishing liquor in the field and is prepared from the preparation raw material of common antistatic finishing liquor not in the field; meanwhile, the antistatic effect is obvious, and the treatment difficulty of generated wastewater is small;through the working procedures of two times of dipping and two times of drying, the antistatic finishing effect is strengthened, thus the antistatic performance of the woolen textiles is improved, theusing quality of the woolen textiles is improved, and then the woolen textiles are processed into top-grade woolen textiles.

Description

Technical field: [0001] The invention relates to the technical field of textile processing, in particular to an antistatic finishing process for wool textiles. Background technique: [0002] Wool textile processing refers to spinning and weaving production activities using wool tops and wool-type chemical fibers as raw materials, as well as dyeing and finishing processes such as bleaching, dyeing and printing of wool textiles. In recent years, the electrostatic phenomenon of pure wool and cashmere textiles has become more and more serious. The reason is that some enterprises have performed inappropriate softening and finishing of pure wool textiles. [0003] The causes of static electricity in wool textiles can be summarized as follows: (1) As pure wool textiles are not easy to care for, people increasingly like clothing made of blended fabrics such as wool and polyester, and the higher the proportion of polyester fibers mixed into wool fabrics, The electrostatic phenomenon must b...
