Abstract

The invention discloses a production technology of silk down feather and belongs to the field of clothing materials. The production technology of the silk down feather comprises the following steps: firstly, washing, degreasing, purifying and drying the silk down feather and then treating the silk down feather with pre-treating liquid; secondly, feeding the down feather into a glutaraldehyde aqueous solution, and pouring silk micro powder, casein, bacterial cellulose and polylactic acid fibers after the reaction is finished; carrying out ultrasonic reaction and heat treatment on filtrate; thirdly, feeding a product obtained in the second step into post-treatment liquid, treating, washing and drying to obtain the silk down feather. According to the production technology disclosed by the invention, the air permeability and the softness of the silk down feather are improved by adopting the casein, the bacterial cellulose and the polylactic acid fiber as a reinforcement system.

Description

technical field [0001] The invention relates to the field of clothing materials, in particular to a production process of silk down. Background technique [0002] Down fiber is a kind of natural animal protein fiber. It is light, bulky, breathable and moisture-permeable, and has excellent warmth retention effect. It is often used in down clothing and products. In the production process, down raw materials need to undergo a series of treatments before they can be used as fillers. Down wool materials must go through procedures such as cleaning, degreasing, deodorization, disinfection, and drying. If the pre-treatment process is not handled properly, it will directly affect The use effect of down. [0003] Since down is an animal product, it has the disadvantages of being flammable, easy to be eaten by moths, easy to breed microorganisms, low added value of the product, and high maintenance and washing requirements. Widen the scope of use of down products. Most of the curren...
