Problems solved by technology

At the same time, the method solves the problem that the yucca active ingredient encountered in the process of modifying polyester fiber is not resistant to high temperature, is easily lost and inactivated, resulting in poor antibacterial effect, and the addition of too much yucca active ingredient leads to poor hand feeling of the fabric. Problems that affect the service performance

Abstract

The invention provides a preparation method of polyester large biological fiber containing Yucca schidigera active ingredients, and belongs to the technical field of polyester fiber modification. The preparation method comprises the following steps of firstly extracting the Yucca schidigera active ingredients and preparing a carrier molecular nest, then loading the Yucca schidigera active ingredients into the molecular nest, then performing mixing with polyester chips, polyester composite master batch, a dispersing agent and a lubricating agent, and performing melting and mixing at a high speed to obtain the polyester large biological fiber containing the Yucca schidigera active ingredients. The modified polyester fiber prepared by the method not only can kill harmful bacteria, but also has the function of retaining beneficial bacteria, and meanwhile, the oxidation resistance of the polyester fiber is improved. Meanwhile, the method solves the problems that the antibacterial effect is poor as the Yucca schidigera active ingredients are not resistant to high temperature and prone to loss and inactivation in the polyester fiber modification process, and the hand feeling of a fabric is poor and the wearing performance is affected due to the fact that the addition amount of the Yucca schidigera active ingredients is too large.

Description

technical field [0001] The invention relates to the technical field of polyester fiber modification, in particular to a method for preparing polyester macrobiological fibers containing yucca active ingredients. Background technique [0002] Some modified polyester fibers currently on the market are mainly antibacterial materials, which are made by adding antibacterial agents to polyester fibers. Commonly used antibacterial agents are generally inorganic antibacterial agents, as patent CN 112663165A discloses a kind of copper modified polyester fiber, cotton / tencel / copper modified polyester fiber blended yarn and double-layer fabric and production process, nonyl Copper phenol sulfonate and polyester blend system is melt-spun, which has a good antibacterial effect, and the antibacterial rate reaches 85.2%. Patent CN 111004377A discloses a polyester antibacterial modification process, adding antibacterial agent nano-cuprous oxide to obtain antibacterial effect. Patent CN 1073...
