Embodiment Construction

[0020] First add 900 kg of cold water into the dyeing vat with a volume of 6 cubic meters, heat it to a temperature of about 40°C, add 25 kg of the main additive - methacrylamide (METHACRYLAMIDE) into the dyeing vat, keep the temperature at 40-60°C, and use a water pump Stir for 5-10 minutes.

[0021] Then put the package wrapped with degummed cocoon silk into the dye vat, add 100 kg of water at the same time, heat to 40°C-60°C, and keep warm for 10 minutes.

[0022] Add 3 kg of formic acid and 0.8 kg of ammonium persulfate into the dye vat, heat up to 70°C, keep warm for 60 minutes, and keep the water pump running.

[0023] Drain the water in the dyeing vat, then add clear water to the dyeing vat again, soak the bobbin wrapped with degummed cocoon silk, run the water pump, clean and drain the bobbin wrapped with degummed cocoon silk.

[0024] Add water to the dye vat, and at the same time add 3 kg of hydrogen peroxide with a concentration of 95%, and 1 kg of detergent (commo...

Abstract

A dynamiting process after cocoon silk degumming contains 1, adding fresh water and additive of methacrylamide in dyeing vessel, then heating to 40-60 degree centigrade, 2, steeping bobbin wound with degummed silk, 3, adding formic acid, ammonium persulphate steeping again in dyeing vessel, 4, steeping said bobbin with fresh water, then taking out said bobbin wound with degummed silk. Said invention has advantages of soft hand, fine brilliance, improved crease resistance, drapability, firmness, absorbent quality and less weightlessness.

Description

technical field [0001] The invention relates to a process for treating cocoon silk, in particular to a process for increasing the weight of cocoon silk after degumming. Background technique [0002] Each cocoon silk consists of two main components: silk fibroin and sericin. Silk fibroin is the main body of silk fiber, and sericin is coated on the outside of silk fibroin to protect it. Silk fibroin is necessary for silk fabrics, and sericin needs to be removed at the end, because sericin has the function of protecting silk fibroin, and generally fabrics are not partially removed until the final dyeing and finishing. Since sericin is a polymer substance in a gel state, it is usually soluble in water, and we usually use boiling water for degumming. Sericin covers the surface of silk fibroin, which makes the silk feel hard. If the degumming time is too long, it will seriously damage the silk fibroin, weaken the strength of the silk fabric, and affect the life of the fabric. ...
