Embodiment 1

[0015] A wool sliver protease mercerizing process, comprising the steps of:

[0016] 1) Pretreatment: The wool strips are soaped and washed in sequence to remove impurities in the wool strips, and then dehydrated and dried;

[0017] 2) Hydrogen peroxide bleaching pretreatment: soak the wool strips treated in step 1) into the hydrogen peroxide treatment solution, soak for 30 minutes and then dedry, wherein the composition and mass ratio of the hydrogen peroxide treatment solution are: hydrogen peroxide 15%, 12% citric acid, 3% sodium pyrophosphate, 5% thiourea dioxide, 65% water;

[0018] 3) Protease mercerizing treatment: dip the wool slivers treated in step 2) into a 3% Sinospin protease solution for two dipping and two rolling treatments, wherein the temperature of the Sinospin protease solution is 50°C, and the remaining The rate is 60%;

[0019] 4) Washing and drying: Finally, wash and dry the wool sliver treated in step 3) to obtain a mercerized wool sliver.

Abstract

The invention discloses a wool top protease mercerizing finish process which includes the steps: 1) pretreatment; 2) hydrogen peroxide bleaching pretreatment: dipping wool tops treated in the step 1) in hydrogen peroxide treating fluid for 30-40 minutes and then drying the wool tops; 3) protease mercerizing treatment: dipping the wool tops treated in the step 2) in 3-4% median protease solution and performing dipping twice and rolling twice; 4) washing and drying. Hydrogen peroxide treating fluid comprises, in weight percentage, 15%-25% of hydrogen peroxide, 10%-15% of citric acid, 2%-7% of sodium pyrophosphate, 5%-8% of thiourea dioxide and 50%-65% of water, and liquor detention rate is 60-80%. By the mode, hydrogen peroxide bleaching pretreatment is combined with protease mercerizing treatment, the whiteness, the glossiness and the felt resistance of the wool tops can be effectively improved, and harmful gas cannot be generated in the treatment procedure, so that the wool top protease mercerizing finish process is safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of wool top treatment, in particular to a mercerizing and shrink-proof finishing process for wool tops. Background technique [0002] Wool strips have excellent elasticity and warmth retention, but the felting and itching of wool strips affect their usability, so wool strips need to be mercerized and shrink-proof. The mercerizing process commonly used by enterprises is the chlorination method, but the chlorination treatment will cause the color of wool strips to turn yellow, and at the same time, it will produce adsorbable organic chloride AOX, which will cause serious environmental pollution. Contents of the invention [0003] The technical problem mainly solved by the invention is to provide a protease mercerizing process for wool sliver, which can solve the defects existing in the existing wool sliver mercerizing process. [0004] In order to solve the above-mentioned technical problems, a technical solution ado...
