Antibacterial natural silk fiber product and preparation method thereof

Abstract

The invention discloses an antibacterial natural silk fiber product and a preparation method thereof; the preparation method comprise the steps of preparing a formic acid solution, wherein the mass concentration of the formic acid is 60-90%; then adding silver salt and inorganic titanium salt water into the formic acid solution, wherein the silver salt is one or more of silver nitrate, silver chloride, silver bromide and silver fluoride, and the inorganic titanium salt water is titanium tetrachloride; and slowly stirring to obtain a treatment solution, wherein in the treatment liquid, the massconcentration of the silver salt is 0.5-15%, and the mass concentration of the inorganic titanium salt water is 0.5-15%; cleaning natural silk fibers; then soaking the natural silk fibers in warm water for a period of time before airing; then soaking the natural silk fibers in a surfactant for a period of time, wherein the surfactant is a quaternary ammonium salt solution; soaking the treated natural silk fiber product in the treatment solution, and allowing to stand in the dark for 1-2 days; and then washing and drying the natural silk fiber product to obtain the antibacterial natural silk fiber product.

Description

technical field [0001] The invention relates to the technical field of fiber production and processing, in particular to an antibacterial natural silk fiber product and a preparation method thereof. Background technique [0002] Silk is a continuous long fiber formed by the solidification of the silk liquid secreted by cooked silkworms when they cocoon. It is also called natural silk and is a natural fiber. Humans utilized one of the first animal fibers. Silk is one of the products of ancient Chinese civilization. The Chinese laboring people invented and produced it very early. According to legend, the concubine of the Yellow Emperor Luozu first taught the people to raise silkworms. According to archaeological discoveries, about 4,700 years ago, silk was used in China to make silk threads, weave ribbons and simple silk fabrics. During the Shang and Zhou dynasties, silk was used to weave silk products such as Luo, damask, Wan, yarn, crepe, Qi, brocade and embroidery. Silkw...
