Embodiment 1

[0024] The processing technology of silkworm velvet quilt: follow the steps below:

[0025] (1) Silk floss

[0026] The silkworm cocoons are boiled, cocoons are peeled to remove pupae, cotton pockets are made, and handmade silk cotton sheets are made.

[0027] (2) Qualitative

[0028] By characterizing the sericin retained on the fiber, it is difficult to denature again, thereby minimizing the hardening phenomenon.

[0029] Specific qualitative process:

[0030] The qualitative agent is: a mixed solution of basic chromium sulfate, protein protectant and tetrakis hydroxymethyl phosphonium salt, wherein the mass concentration of basic chromium sulfate is 0.03%, protein protectant (glycerol): 0.01%, tetrakis hydroxymethyl chloride Phosphate: 0.01%. Bath ratio: 1:20, temperature 50°C, reaction time 24h.

[0031] After processing, take it out, dehydrate and dry the surface moisture.

Abstract

The invention discloses a silk fiber sericin qualitative agent, wherein alkaline chromium sulfate has a mass concentration of 0.03% to 5%, a protein protectant has a mass concentration of 0.01% to 0.3%, and tetrahydroxymethyl phosphate has a mass concentration of 0.01% to 10%. The invention also discloses a processing technique of a mulberry silk quality, including the steps of qualitatively processing silk pads: adding the silk pads into the silk fiber sericin qualitative agent to qualitatively process the sericin; spraying proteinase composite liquid to the silk pads with the sericin qualitatively processed, napping by friction, enzymatically deactivating, softening, drying, blowing with cold air, performing acid condensation or salt condensation, and subjecting the silk pads to hydrophilic treatment by using a cationic hydrophilic agent; carrying out combing and quilting to obtain the finished silk quilt. The processed silk quilt is free of caking and good in warmth retention.

Description

technical field [0001] The invention relates to a silk fiber sericin qualitative agent and a processing technique for a silk velvet quilt, belonging to the technical field of silk processing. Background technique [0002] Silk is a natural protein fiber. It is mainly composed of silk fibroin and sericin, of which sericin accounts for 10% to 40%. The 18 kinds of amino acids contained in silk protein have health care and nutrition effects on the human body. In fact, silk protein is very similar to human skin keratin protein, and regular contact with silk protein can significantly improve skin conditions, so silk is often made into non-woven fabrics for beauty products and various bedding. [0003] Silk quilts have been in my country for many years, and are loved by the general public for their excellent skin-friendly properties and breathability. But at the same time, there is also a fatal problem in silk quilts, that is, the warmth retention is not durable. The main reaso...
