Embodiment 1

[0009] Embodiment 1: with reference to attached figure 1 and 2 . A finishing method of ε-polylysine synergistically with biomimetic enzymes, using metal phthalocyanine biomimetic enzyme grafted fibers as the starting point, the natural food-grade antibacterial agent ε-polylysine and styrene acrylate copolymer through foam particles Form, attached to the bionic enzyme viscose fiber and polypropylene fiber mixed carding material, set the upper and lower two-level online synchronous moisture detection device to detect the moisture content of the product before and after foam finishing, and automatically measure the ε- The amount of poly-lysine attached, and automatically adjust the pressure and flow rate of foam finishing slurry according to the feedback of the measurement results, to prevent the deodorization effect of bionic enzymes covered by too much ε-polylysine and the lack of ε-polylysine to affect the antibacterial efficiency , so that the surface of the fine denier bio...

Embodiment 2

[0010] Example 2: On the basis of Example 1, using the fiber as a carrier, the cellulose fiber is cationic modified, and then combined with the phthalocyanine containing a carboxylic acid group through electrostatic interaction to obtain a metal phthalocyanine biomimetic enzyme cellulose fiber , or the metal phthalocyanine biomimetic enzyme polypropylene fiber can be prepared by melt spinning.

Abstract

The invention relates to an epsilon-polylysine collaborative bionic enzyme finishing method, which can not only block viruses and bacteria but also further kill viruses and bacteria so as to prevent transfer infection, and is capable of achieving actual blocking and protecting functions. A copolymer of epsilon-polylysine, which serves as a natural food-grade antibacterial agent, and styrene acrylate is attached onto a bionic enzyme viscose and polypropylene fiber carded material in a form of foamed particles by taking metal phthalocyanine bionic enzyme grafted fiber as an entry point, upper and lower online synchronous moisture detection devices are arranged to detect the moisture content of a product before and after foam finishing respectively, the attaching amount of epsilon-polylysine is automatically measured and calculated, and foam finishing sizing pressure and flow are automatically regulated depending on measuring and calculating result feedback, thereby avoiding the phenomena that a deodorizing effect of bionic enzyme is masked when epsilon-polylysine is excessive and the antibacterial efficiency is influenced if epsilon-polylysine is insufficient; therefore, epsilon-polylysine is stably and uniformly attached onto the surfaces of the fine denier bionic enzyme viscose and polypropylene fiber.

Description

technical field [0001] The invention relates to a ε-polylysine synergistic biomimetic enzyme finishing method that can not only block viruses and bacteria, but also further kill viruses and bacteria, prevent their transfer infection, and can play a real barrier and protection role, belonging to spunlace The field of medical material manufacturing. Background technique [0002] CN101633736A, titled "biological antibacterial protective material and its preparation method", including at least one biological antibacterial agent and polyethylene terephthalate combined through covalent bonds, and the biological antibacterial agent is ε-polylysine acid, polymyxin sulfate, nisin, or natamycin. Its disadvantages: because the carrier itself cannot achieve the effect of blocking viruses and bacteria, the effect of blocking viruses and bacteria is not good. Contents of the invention [0003] Design purpose: to avoid the deficiencies in the background technology, to design a ε-polyly...
