Abstract

The invention discloses a preparation process of warm-keeping and antibacterial fiber. The preparation process comprises two impregnation steps. The preparation process has the advantages that the antibacterial fiber is prepared with an electrostatic self-assembly technology by impregnation of a fabric in an antibacterial finishing solution with an opposite charge, so that the internal structure of the fiber is not damaged, and an antibacterial effect can be achieved; a hollow fiber is used as a fiber body, and warm keeping and cold resisting functions are realized; besides, an inorganic antibacterial agent is used, and potential harm to human bodies by organics is reduced.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a preparation process of a warm-keeping and antibacterial fiber. Background technique [0002] With the advancement of science and technology, people's living standards have improved, and consumers have higher and higher requirements for textiles. They are no longer simply beautiful and durable, but need additional multi-functional and beneficial elements, especially for antibacterial and antibacterial. and sterilization of textiles demand is increasing. At present, the fibers used to prepare textiles do not have antibacterial ability, and under certain conditions, they will provide an environment for bacteria to survive and reproduce, threatening human health. [0003] At present, the main method to realize the antibacterial function of fibers is through surface modification technology and blending modification technology. The former is to attach the antibacterial...
