Abstract

The invention discloses medical antibacterial ES fiber and a preparation technology thereof. The medical antibacterial ES fiber is sheath core fiber, and is made of sheath layer materials and core layer materials. The sheath layer materials are prepared from 6-9 parts of sheath layer resin, 2-3 parts of addition agents, and 0.8-1.5 parts of antibacterial agents; and the core layer materials are prepared from 6-9 parts of core layer resin, 2-3 parts of addition agents, and 0.8-1.5 parts of antibacterial agents. The preparation technology comprises the steps of preparing the antibacterial agents, preparing the sheath layer materials and the core layer materials and preparing finished products through blend spinning of the sheath layer materials and the core layer materials. The antibacterialagents are prepared from modified juniper oil and nanocore-shell particles with a mass ratio of 1 to 1, and the modified juniper oil is mainly prepared from juniper oil, mesoporous silicon dioxide, 3-aminopropyl triethoxysilane and polyacrylic acid through reaction; and the nanocore-shell particles are mainly prepared from silver nitrate and ferric nitrate. The obtained medical antibacterial ES fiber is high in antibacterial activity and is enduringly antibacterial, and the problem of weak antibacterial effect brought by effumability of the juniper oil is solved.

Description

technical field [0001] The invention belongs to the technical field of fiber manufacturing, in particular to a medical antibacterial ES fiber and a preparation process thereof. Background technique [0002] ES fiber is a skin-core composite fiber obtained by successfully combining low-melting point components and high-melting point components on a monofilament. Quality of nonwoven products. The low-melting-point fibers in ES fibers are melted under heat treatment conditions higher than their melting point, and bonded with other materials to form non-woven fabrics without binders. The first generation of ES fiber was successfully developed by Chisso Corporation of Japan. Its skin layer is PE (polyethylene) and its core layer is PP (polypropylene). Now PE / PET (polyethylene / polyester) composite ES fiber has been developed, the skin layer is PE, and the core layer is PET (polyester). [0003] Because ES fiber is a kind of cleaning fiber without binder, it has been widely used...
