Wool fiber surface modification method

Abstract

A wool surface scale modification method adopts wool loose fiber, wool top, wool yarns or wool garment as wool to-be-treated products and is conducted according to the following steps sequentially: a, preparing treatment liquid; taking sodium cyanate, sodium pyrophosphate, hydrogen peroxide at the concentration of 30 percent and the balance of water, wherein in the prepared treatment liquid, the liquid sodium cyanate concentrate is 1 to 20 g / L, the sodium pyrophosphate concentration is 0 to 20 g / L and the hydrogen peroxide concentration is 10 to 70 g / L; and b, soaking the wool to-be-treated product in the above treatment liquid at the mass ratio of the to-be-treated wool to the treatment liquid being 1:15 to 1:25, maintaining the temperature of the treatment liquid at 30 to 70 DEG C, and performing oscillation in an ultrasonic oscillating instrument for 10 to 60 minutes.

Description

technical field [0001] The invention relates to a method for modifying wool, in particular to a method for using sodium cyanate / hydrogen peroxide system to catalyze oxidation corrosion to destroy the scale structure on the surface of wool fiber. Background technique [0002] Wool is a high-grade natural textile fiber material commonly used in the manufacture of textile products such as suits, fashion and knitted sweaters. However, the scale layer covered on the surface of the wool fiber will cause wool textiles to shrink during the washing process, changing the size and shape of the garment, affecting the appearance and performance of the garment; It blocks the penetration and diffusion of dyes into the fiber, which affects the dyeing and printing performance of wool, etc.; and the scale structure makes the appearance of wool textiles not bright enough, not bright enough, not smooth and soft enough to feel, etc. Therefore, in the processing of wool textiles, chlorination is...

AI Technical Summary

Problems solved by technology

However, the effect of protease on wool keratin in the current protease modification method is not strong enough, and chlorination or other oxidation treatments are needed before protease treatment, so that protease can exert its digestion effect on wool scale layer keratin; Siroflash technology directly adopts the continuous irradiation of UVC lamps, which has a very limited modification effect on wool, and can only slightly improve the dyeing performance of wool, and will cause yellowing of wool; the investment in plasma treatment equipment is high, and the equipment is not perfect And the low output cannot form mass production, etc.

[0004] At present, there is no modification technology or related patents in China that use sodium cyanate / hydrogen peroxide system to modify the surface scales of wool without chlorine, or use sodium cyanate / hydrogen peroxide system to pretreat wool and then combine biological enzyme treatment
