A kind of silk fiber non-woven fabric and production method thereof

Abstract

The invention provides a silk fiber non-woven fabric and a production method thereof, comprising combing natural fibers or synthetic fibers into a first fiber web and combing degummed silk fibers into a second fiber web through random carding, the first fiber web and The second fiber net forms the base cloth layer and the contact layer respectively through spunlace compounding, and the fiber in the contact layer is wrapped with a protective layer made of silk fibroin. The present invention uses a small amount of degummed silk fiber to form the contact layer that contacts the skin, and The degummed silk fibers are dissolved into a silk fibroin solution, and the silk fibroin solution is used to cover the fibers in the contact layer, so that the side contacting the skin is completely composed of non-irritating silk fibroin, which reduces the consumption of silk fibers and maintains the properties of silk fibers.

Description

technical field [0001] The invention relates to the field of textile materials, in particular to a silk fiber nonwoven fabric and a production method thereof. Background technique [0002] Silk is a natural protein fiber including 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 silk fibroin. Silk fibroin is non-toxic to the human body, safe and reliable, has good biocompatibility, and is suitable for developing into functional materials. Silk fibroin is rich in protein and contains 18 kinds of amino acids. Among them, leucine can accelerate the metabolism of cells, serine and threonine can delay skin aging, and tryptophan and tyrosine can absorb ultraviolet rays. The excellent functions are transferred to the edible fibers that get along with human beings day and night, care for human skin, and make human beings have healthy skin. [0003] The advantages of silk products have deepened pe...

Problems solved by technology

[0003] The advantages of silk products have deepened people's requirements for modification and endowed them with more functions, such as sterilization, etc. The traditional method is to treat silk products by infiltrating or spraying the drug, due to the structure of silk itself Its surface is smooth, which makes it have a good hand feeling, but the output of natural silk is limited, so the price is relatively expensive, and it is difficult to use a large number of silk products in the field of contact consumables that are suitable for using silk to prevent allergies
