Antistatic wool anti-shrinking agent and wool processing method with same

Abstract

The invention provides a wool anti-shrinking agent and a wool processing method with the same. After the wool anti-shrinking agent and the wool processing method are used, the shrinkage rate of a wool fabric can be reduced to about 1%, the phenomenon of pilling caused by bonding generated when wool is washed can be prevented, and the washed wool fabric is bright in color and does not easily turn yellow. According to the formula, the wool anti-shrinking agent is good in water solubility, can achieve a good washing effect at room temperature, is easy to wash, is free from any chemical damage to wool products and does not produce formaldehyde residue; the wool anti-shrinking agent has effective functions of decontamination, static electricity resistance and bacteria and mold prevention for the wool fabric; the wool fabric washed by the wool anti-shrinking agent is soft in texture and has lasting natural faint scent. The antistatic wool anti-shrinking agent is less in dosage when being used for processing the wool fabric, and the content of organic halide with adsorbability in waste water is low; when chloride waste water is treated by a flocculating agent, organic halide with adsorbability in the waste water is reduced by about 90%, and thus the problem that the environment is polluted by the waste water can be solved.

Description

technical field [0001] The invention belongs to the technical field of textile chemicals, in particular to an antistatic anti-shrinkage agent for wool and a method for treating wool. Background technique [0002] With the improvement of people's living consumption level year by year, consumers' demand for high-grade wool fabrics has increased rapidly. But the surface of the wool fiber is covered with a layer of scales, which makes the wool products easy to deform and fluff, and it is easy to shrink after washing, which seriously affects the use of wool fabrics. Anti-shrinkage can be achieved by treating the wool scale layer with oxidants, but the commonly used oxidants such as persulfuric acid or potassium permanganate will cause serious loss of strength of wool fibers, and the treated wool has peculiar smell and is easy to yellow, which is not suitable for dyeing. Fastness and shade also play a role, affecting the aesthetics of wool fabrics. If the prior art chlorinating ...

Problems solved by technology

However, the surface of wool fiber is covered with a layer of scales, which makes wool products easy to deform and fluff, and it is easy to shrink after washing, which seriously affects the use of wool fabrics.

Anti-shrinkage can be achieved by treating the wool scale layer with oxidants, but the commonly used oxidants such as persulfuric acid or potassium permanganate will cause serious loss of strength of wool fibers, and the treated wool has peculiar smell and is easy to yellow, which is not suitable for dyeing. Fastness and shade are also affected, affecting the aesthetics of wool fabrics

Using the chlorinating agent of the prior art to carry out anti-shrinkage treatment on wool, the treated wool is easy to yellow and its elasticity is easily damaged, and the adsorbable organic halides contained in the treated wastewater will produce organic chlorine to pollute the environment

[0003] Patent CN 103666790 A discloses a wool fabric anti-mildew and anti-shrink cleaning agent and its preparation method, but the cleaning agent uses a variety of organic surfactants, which has poor water solubility at room temperature, makes it difficult to wash and rinse wool fabrics, and is organic The surfactant is not easy to degrade, and the wool fabric washed with this cleaning agent for a long time will cause certain harm to the human body, and the problem of sewage treatment after scaling treatment is not involved

Patent CN 102899892 A discloses an anti-shrinkage treatment agent for wool fabrics, but the treatment agent can produce formaldehyde during use, which will cause harm to the human body, and does not involve the problem of sewage treatment after shrinkage treatment
