Method for producing high-elasticity bulked silk-cotton quilt

Abstract

The invention relates to a method for producing a expanded silk wadding, which includes: sort cocoons, boil at high temperature, degelatinize, shuck the cocoons to remove silkworm, wash, loosen by drawing and make them into silk piece, dewater, dry and draw to make the silk wadding. The invention features that the cocoons before high temperature boiling process are vacuum soaked and expanded by a expanding liquor, concretely the cocoons before high temperature are suctioned into the expanding liquor heated by 80-95 degreeC under vacuum condition, soaked uniformly and expanded in slight boiling state. The said expand is made from amphoteric surfactant. The cocoons after being made into silk pieces and before dewatering are conducted an after finishing by a silk softening agent. Advantages: the patches and stem cubes resulted from un-uniform boiling or in-complete degelatinizing of cocoons are largely reduced; the silk floss is very soft because of full expanding.

Description

technical field [0001] The invention relates to a method for preparing silkworm cocoon processed products used for keeping warm in daily life, in particular to a method for producing a highly elastic puffed silk quilt. Background technique [0002] Silk quilt is a kind of silkworm cocoon processing product, which is an important export commodity in my country's traditional silk industry. It has the characteristics of softness, comfort, and excellent warmth retention. Since silk is an animal protein fiber and contains 18 kinds of amino acids, its direct contact with the human body can increase the vitality of skin cells, promote the metabolism of skin cells, and have a maintenance function for the skin. Silk cotton quilts are favored by consumers at home and abroad for their many excellent health care functions on the human body. [0003] The traditional silk cotton quilt processing method is to cook cocoons at high temperature for sorted and treated...

AI Technical Summary

Problems solved by technology

Although the silk floss quilt processed by the above method has excellent wearability when the processing is completed, it is easy to stick and tangle between the silk fibers after long-term use, thereby reducing the elasticity, softness and warmth retention of the silk floss.

Therefore, it is necessary to turn over the silk floss at intervals to make the silk fibers fluffy and dispersed, and then the characteristics of softness, comfort and warmth retention can be restored, which brings great inconvenience to users.
