Expanded silk quilt based on mulberry silk and preparation method thereof

Abstract

The invention discloses an expanded silk wadding quilt based on mulberry silk and a preparation method of the expanded silk wadding quilt. The preparation method comprises the following steps: addinga mixed solution of turmeric extract, acetic acid and carboxymethylcellulose into a degummed silk fiber solution, performing ultrasonic treatment, adding polyurea-formaldehyde and selenocysteine hydrochloride, and performing ultrasonic treatment; preparing perforated silk into silk floss pieces, and impregnating in an aqueous solution of amino polyethylene glycol so as to obtain treated silk flosspieces; putting the treated silk floss pieces into a rotatable closed container filled with a rupture disk, and expanding to obtain expanded wet silk floss pieces; dehydrating the expanded wet silk floss pieces, manually garneting, and drying to obtain expanded silkworm dried silk floss pieces; and combining and sewing the expanded silkworm dried silk floss pieces and treated tussah silk floss pieces, thereby obtaining the expanded silk wadding quilt. The porous expanded silk floss pieces with excellent service performance are successfully prepared, and the expanded silk wadding quilt has excellent antibacterial property and also has positive practical significance.

Description

technical field [0001] The invention relates to a preparation method of silk floss, in particular to an expanded silk floss quilt based on mulberry silk 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 e...

AI Technical Summary

Problems solved by technology

[0003] Mulberry silk is soft and has been widely used in the field of making silk quilts, but its mechanical properties are poor, especially after expansion, so there are almost no reports about porous expanded mulberry silk in the prior art

[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
