A kind of anti-felt shrinkage machine washable finishing method of wool fabric

Abstract

The invention discloses a felt proofing machine-washing finishing method for wool fabric. Under the effect of ultrasonic waves, the wool fabric is subjected to chlorination pretreatment to realize mild scale stripping treatment, and then the wool fabric is subjected to enzyme treatment to realize controlled scale stripping treatment under effect of the ultrasonic waves, so that the inside and outside uniformity of yarns of which the wool surface is subjected to scale stripping is effectively increased. The chlorination pretreatment is combined with the enzyme treatment, so that the longitudinal scale stripping uniformity of fibers is effectively increased, therefore the felt proofing effect of the wool fabric is achieved, and the machine-washing purpose of wool textiles is realized. Meanwhile, the reaction in the method is carried out in a scale layer, so that the damage on intercellular substances of the inner layers of the fibers is reduced, and the wearing performance and the durability of the wool textiles are increased.

Description

technical field [0001] The invention relates to a fabric treatment method, in particular to a wool fabric anti-felting machine washable finishing method. Background technique [0002] Wool is an important raw material for the textile industry. It 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 and are favored by people. . However, wool fabrics are prone to felting. The felting of wool fabrics is mainly caused by the surface scale characteristics of wool. Under the action of washing, wool is prone to "directional movement" effect, resulting in the "agglomeration" effect of wool fibers, that is, the loss of wool fibers. Elasticity and curling will make the wool fabric shrink, and then cause the dimensional stability of the wool fabric to deteriorate, seriously affecting the appearance and wearability of the wool fabric. ...

AI Technical Summary

Problems solved by technology

Generally, the chlorination method is used for descaling, but it has the following problems: 1) 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 inside and outside the fibers, thus The yarn fiber is damaged, which seriously affects the strength, color and other properties of the wool fabric; 2) It needs to use a large dose of descaling agent for descaling treatment. Conducive to environmental protection

At present, there are also some new processes and combinations of processes for the anti-felting treatment of wool fabrics. Although these new processes can achieve the anti-felting effect of wool fabrics, the inner and outer yarns and the longitudinal treatment are uneven, especially the inner and outer yarns. The degree of descaling of fibers varies greatly, which causes many problems, such as great impact on the physical properties of wool fabrics such as strength, tearing, and weight; it has a great impact on the style, feel, and wearing comfort of wool fabrics; It has a great influence on the durability of wool fabric; it has a great influence on the dyeing of wool fabric; the effect stability and reproducibility of anti-felting treatment are poor, etc.
