Goose down based expanded silk wadding quilt and preparation method thereof

Abstract

The invention discloses a goose down based expanded silk wadding quilt and a preparation method thereof. The preparation method of the goose down based expanded silk wadding quilt comprises the following steps: adding a mixed solution of turmeric extract, vinegar and carboxymethylcellulose to a degummed silk fibroin solution for ultrasonic treatment, and adding polyureaformaldehyde and selenocystamine dihydrochloride for ultrasonic treatment; preparing silk wadding sheets from silk with holes and impregnating the silk wadding sheets in an amino polyethylene glycol aqueous solution to obtain treated silk wadding sheets; putting the treated silk wadding sheets in a rotatable closed container filled with a rupture film for expansion to obtain the expanded wet silk wadding sheets; dehydratingand unloosening the expanded wet silk wadding sheets manually and drying the same to obtain the expanded dry silk wadding sheets; and combining and sewing the expanded dry silk wadding sheets with thetreated goose down to obtain the expanded silk wadding quilt. The porous expanded silk wadding sheets which are excellent in wearability are prepared successfully and have good bacterial resistance,and the preparation method has realistic positive meaning.

Description

technical field [0001] The invention relates to a preparation method of silk floss, in particular to an expanded silk floss quilt based on goose down and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people are more and more advocating returning to nature. The consumption of pure natural silk quilts has increased sharply, and the consumer market has expanded year by year. The raw materials of silk cotton quilts are all kinds of real silk, among which, silk cotton quilts made of porous expanded silk have better elasticity, warmth retention, softness and other wearing properties than ordinary silk cotton quilts. Porous bulked silk refers to the silk with a porous structure inside the silk fiber. Because the porous structure can form many small spaces for storing air, it can store a large amount of still air, so it has good warmth retention, and good air permeability and moisture permeability. , has received exte...

Problems solved by technology

[0003] Goose down is mostly used to keep warm after being stuffed into something. It is divided into down and wool flakes. The down mainly refers to the fluff under the goose belly, and the wool flakes will have some stalks. In the past two years, the popularity rate of goose down quilts in the market It is getting higher and higher, but the quality is uneven; more importantly, due to the moisture absorption of goose down, its products are prone to bacteria

[0004] The existing methods for preparing expanded yarns are not effective and require the use of a large amount of chemical reagents, which does not meet the theme of green environmental protection
