Environmentally-friendly wool and cotton blended fabric scale stripping treatment technology

Abstract

The invention discloses an environment-friendly wool and cotton blended fabric descaling treatment process. Under the action of ultrasonic waves, the process includes double treatment of enzyme treatment and calcium carbonate grinding, which effectively improves the uniformity of descaling treatment on the wool surface, reduces the Cellular damage to the inner layer of the fiber improves the wearability and durability of wool blend fabrics. This process does not use heavy metals, halides and other substances harmful to the human body and the environment, and is an environmentally friendly fiber treatment process.

Description

technical field [0001] The invention relates to a fabric processing method, which belongs to the field of textiles, and in particular to a scale-stripping process of wool and cotton blended fabrics. Background technique [0002] Modern people pay more and more attention to improving the quality of life. Wool has many excellent properties, such as good elasticity, strong moisture absorption, not easy to stain, good warmth retention, soft luster, etc. These properties make wool fabrics have various unique styles. favored by people. However, wool is prone to felting. The felting of wool fabrics is mainly caused by the surface scales of wool. Under the action of washing, wool is prone to "directional movement" effect, resulting in the "agglomeration" effect of wool fibers, that is, wool fibers lose their elasticity. And crimp, so that the wool fabric shrinks, and then causes the dimensional stability of the wool fabric to deteriorate, seriously affecting the appearance and wear...

Problems solved by technology

Generally, the chlorination method is used for descaling, but it has the following problems: First, in order to achieve the descaling of the fibers inside the yarn, it is bound to treat the fibers on the surface of the yarn too heavily, resulting in uneven descaling of the fibers inside and outside, thus damaging The yarn fibers are destroyed, which seriously affects the strength and color of wool fabrics; the second is that it needs to be treated with a large dose of descaling agent, but a large dose of descaling agent pollutes the environment very much, which is not conducive to environmental protection. There are also some new processes and process combinations for the anti-felting treatment of wool fabrics. Although these new processes can achieve the anti-felting effect of wool fabrics, most of the effects have poor stability and reproducibility.

Chinese invention patent CN103031704A discloses an anti-felting machine-washable finishing method for wool fabrics. This method combines descaling treatment with enzyme treatment and ultrasonic treatment, and basically realizes the controllable treatment of descaling. Among them, chlorination pretreatment is still required, and halogen is added, which still has a certain impact on the environment
