Abstract

The invention provides a preparation method of silk composite heat insulation fiber. The method comprises the following steps of (1) making vanadium pentoxide, yttrium oxide and magnesium acetate into composite fiber by a sol-spinning method; (2) performing pretreatment on the composite fiber by organic silicon oil to obtain pre-treatment composite fiber; (3) performing degumming on the silk fiber through sodium carbonate; then, performing regeneration by calcium nitrate; next, dissolving the silk fiber into methanoic acid to obtain the silk protein solution; (4) adding the pre-treated composite fiber into the silk protein solution to be made into spinning solution; after the static spinning, obtaining the silk composite heat insulation fiber. The prepared silk composite heat insulation fiber has good heat insulation performance and can be used in occasions with high heat insulation requirements.

Description

technical field [0001] The invention relates to a silk fiber, in particular to a preparation method of a silk composite thermal insulation fiber. Background technique [0002] Silk is a continuous long fiber formed by coagulation of the silk liquid secreted by cooked silkworms, also known as natural silk. It is the lightest, softest and thinnest natural fiber in nature. It is mainly composed of animal protein and is rich in eighteen kinds of human body Essential amino acids can promote skin cell vitality, prevent vascular sclerosis, long-term use can prevent skin aging, have special antipruritic effects on certain skin diseases, and have certain health care effects on arthritis, frozen shoulder, and asthma. It has the reputation of "the second skin of the human body" and "fiber queen". Because silk is light and slender, the fabric has good luster, is comfortable to wear, feels smooth and plump, has poor heat conduction, moisture absorption and breathability, which determine...
