Embodiment 1

[0017] Example 1: A biomimetic enzyme biological protection spunlace material, ε-polylysine is attached to the surface layer of biomimetic enzyme viscose fiber and flame-retardant polypropylene fiber, and the biomimetic enzyme adhesive with ε-polylysine part of the surface layer Glue fiber and flame-retardant polypropylene fiber spunlace form the middle sterilization and deodorization layer of the nonwoven mask. The fine denier biomimetic enzyme viscose fiber and flame-retardant polypropylene fiber with a fineness not exceeding 0.9dtex are used as fiber raw materials. The pore size of the middle layer of the non-woven biological protective mask is 2-7 microns, and the porosity is 85-90%. The concentration of ε-polylysine grafted and attached to the sterilization and deodorization layer in the middle of the nonwoven mask is 0.1-0.2%.

Embodiment 2

[0018] Example 2: On the basis of Example 1, a production method of a biomimetic enzyme biological protection spunlace material, through AI monitoring high-density carding technology, microneedle high-pressure spunlace technology and ε-polylysine synergistic biomimetic enzyme finishing technology , using a foam finishing machine to attach ε-polylysine to the surface layer of biomimetic enzyme viscose fiber and flame-retardant polypropylene fiber, and then dry and shape it to make it have antibacterial and deodorant functions. AI monitoring technology uses modern intelligent information processing means to emit X-rays through the X-ray generator to measure the fiber layer density in the cotton feeding area to monitor the uniformity of the fiber layer in the cotton feeding area in real time. , the X-ray receiver receives the cotton layer weight signal, and feeds this information back to the digital metering cotton feeding system, and then the feeding regulating valve of the cotto...

Abstract

The invention relates to a mimic enzyme biological protection spunlaced material, which not only can block viruses and bacteria, but also can further kill the viruses and the bacteria to prevent transfer and infection of the viruses and the bacteria and can take real blocking and protecting effects, and a manufacturing method. Epsilon-polylysine is attached to a part of surface layers of mimic enzyme viscose and flame resistant polypropylene fibers; the mimic enzyme viscose and the flame resistant polypropylene fibers, which are provided with partial epsilon-polylysine surface layers, are spunlaced to form an intermediate sterilization and deodorization layer of a non-woven mask. By an AI (Artificial Intelligence) monitoring high-density carding technology, a microneedle high-pressure spunlacing technology and an epsilon-polylysine synergistic mimic enzyme finishing technology, a foam finishing machinery is adopted to attach the epsilon-polylysine to the surface layers of the mimic enzyme viscose and the flame resistant polypropylene fibers; then by drying and sizing, the mimic enzyme biological protection spunlaced material has antibacterial and odor-resistant functions.

Description

technical field [0001] The invention relates to a biomimetic enzyme bioprotective spunlace material which can not only block viruses and bacteria, but also further kill viruses and bacteria, prevent their transfer infection, and can play a real role of barrier protection, and a production method, which belongs to spunlace medical material manufacturing field. 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 desig...
