Embodiment 1

[0021] Fabric: Crepe Chine, 100% Mulberry Silk

[0022] 1) Enter 600l of water into the tank, add 4kg of biological protease SP80 and 1.2kg of sodium bicarbonate into the tank, mix evenly, and configure it as a finishing solution;

[0023] 2) The temperature of the tank body is raised, and the temperature is controlled at about 40°C;

[0024] 3) fabric padding above-mentioned finishing solution, the rate of carrying liquid is 80%, then winding;

[0025] 4) Wrap the fabric with a plastic film, stack it at room temperature for 18 hours, and keep the roller rotating at a speed of 12 rpm;

[0026] 5) Finally, the above-mentioned fabric is re-washed by a continuous refiner to fully remove the sericin on the surface of the fabric. The temperature of the inlet water of the continuous refining machine is raised to 80°C, and the refining agent Miltopan SE: 2g / L is added, and the temperature of the subsequent water washing tank is controlled at 50°C, and the washing time is 30 minutes...

Embodiment 2

[0029] Fabric: Crepe satin, 100% silk

[0030] 1) Enter 600l of water into the tank, add 5kg of alkaline protease and 1.5kg of sodium bicarbonate into the tank, mix evenly, and configure it as a finishing solution;

[0031] 2) The temperature of the tank body is raised, and the temperature is controlled at about 30°C;

[0032] 3) The fabric is passed through the rolling groove equipped with the above-mentioned finishing solution, then padding and rolling, so that the liquid-carrying rate is 70%;

[0033] 4) Wrap the fabric with a plastic film, stack it at room temperature for 20 hours, and keep the roller rotating at a speed of 10 rpm;

[0034] 5) Finally, the above-mentioned fabric is retrained and washed by a jigger to remove the sericin on the surface of the fabric. The dyeing machine is fed with 400l of water, the fabric is lowered into the vat, and 1.5g / L of refining agent FORYL TRL is added, the temperature is raised to 80°C, and the water is drained after re-training ...

Embodiment 3

[0037] Fabric: Silk Sateen, 63% Mulberry Silk 37% Cotton

[0038] 1) Enter 600l of water into the tank, add 3kg of neutral protease and 0.1kg of sodium bicarbonate into the tank, mix evenly, and configure it as a finishing solution;

[0039] 2) The temperature of the tank body is raised, and the temperature is controlled at about 50°C;

[0040] 3) The fabric is passed through the rolling groove equipped with the above-mentioned finishing solution, then padding and rolling, so that the liquid-carrying rate is 90%;

[0041] 4) Wrap the fabric with a plastic film, stack it at room temperature for 24 hours, and keep the roller rotating at a speed of 15 rpm;

Abstract

The invention relates to a real silk or real silk contained fabric protease cold batch degumming refining process and aims at providing the process which can achieve semi-continuous degumming refining treatment to effectively improve the production efficiency. According to the technical scheme, the real silk or real silk contained fabric protease cold batch degumming refining process comprises the following steps that firstly, biological protease, sodium bicarbonate and water are mixed and prepared into finishing liquid, wherein the protease concentration is 5-8 g / L, and the concentration of the sodium bicarbonate is 0.1-3 g / L; secondly, the temperature of the finishing liquid in a groove is raised, and the temperature is controlled within 30-50 DEG C; thirdly, a real silk or real silk fabric passes the roll groove containing the finishing liquid and then is subjected to padding and rolled into a rolled fabric, and the liquid rate of the rolled fabric is 70-90%; fourthly, the rolled fabric is wrapped by a plastic film and is stacked for 18-24 h at the normal temperature; fifthly, the fabric is subjected to finishing scouring through a jig dyeing machine or a continuous refining machine and washed so that gum can be removed, and a refining agent is added to guarantee a finishing scouring washing effect.

Description

technical field [0001] The invention relates to an enzymatic cold stack degumming and refining process for real silk or silk-containing fabrics Background technique [0002] The traditional silk or silk-containing fabric refining process is mainly based on hanging refining, which is generally carried out under strong alkali conditions, and the discharge of waste water will cause great environmental problems, and the fabric is easy to wrinkle during the refining process, resulting in uneven refining, refining Problems of opacity (raw block) and wrinkling. [0003] In recent years, with the continuous development of biotechnology, many high-efficiency proteases have been applied in the enzyme refining of real silk. CN201310154762.2 discloses a method for enzymatic refining of real silk fabrics, in which real silk is soaked in a 50-degree protease refining bath for degumming and refining treatment. CN201410022207.9 discloses a neutral protease refining process for tussah coco...
