Abstract

The invention discloses a high-efficiency antibacterial fiber and a manufacturing method thereof, which mainly includes three steps of preparing antibacterial masterbatch, antibacterial fiber and antibacterial FDY silk. The present invention utilizes nanoscale silver-loaded molecular sieves with small crystal size, large specific surface area, and high silver loading to prepare high-efficiency antibacterial fibers. The content of antibacterial agents (nanoscale silver-loaded molecular sieves) in the fibers is ≤1‰, and the antibacterial rate is over 99%. After repeated washing, the antibacterial effect did not decrease significantly, and the preparation process of the antibacterial fiber does not require the use of organic solvents. The nano-scale silver-loaded molecular sieves used are prepared by a one-pot method without adding any organic templates. The process is simple, low-cost, and green. ,Environmental friendly.

Description

technical field [0001] The invention belongs to the technical field of textile fibers, and in particular relates to a high-efficiency antibacterial fiber and a manufacturing method thereof. Background technique [0002] With the development of science and technology and the improvement of the quality of life, people's health awareness of environmental sanitation is increasing, and the requirements for functional fibers are getting higher and higher. Fibrous woven products (such as towels, underwear, rags, etc.) are indispensable items in daily life. Because they are often in a wet state during use, they are favorable places for the reproduction and reproduction of many pathogenic bacteria, so they also become a source of bacteria transmission. one of the carriers. [0003] Silver ions have the characteristics of high-efficiency antibacterial, high safety, and good compatibility, and are often used as the main component of antibacterial fibers. The existing method is often ...
