AI Technical Summary

Technical Problem

Existing hotel bedding products have short-lasting antibacterial and anti-mite properties, chemical additives are easily lost, physical barriers are prone to aging, and biological enzymes require stringent storage conditions, making it difficult to maintain long-term anti-mite effectiveness.

Method used

By encapsulating bio-enzymes in a metal-organic framework and combining photocatalysis with bio-enzymes, self-cleaning antibacterial and anti-mite fabrics can be prepared, thus broadening the pH range and temperature range of the enzyme reaction and improving durability.

Benefits of technology

It achieves all-weather antibacterial and anti-mite performance by enhancing the adaptability and durability of enzymes through dual protection of photocatalysis during the day and biological enzymes at night.

Abstract

The invention discloses a preparation method of a self-cleaning antibacterial anti-mite fabric, and relates to the technical field of fabric preparation, and the preparation method comprises the following steps: 1-5 g of Cu (NO3) 2.6 H2O, 0.1-1.5 g of isophthalic acid, 20-50 mL of water and a certain antibacterial enzyme mixture are sequentially poured into a glass beaker, stirring is performed for 30 min, uniform mixing is performed, and the antibacterial anti-mite fabric is obtained; pouring the mixture into a 25mL polytetrafluoroethylene inner container, putting the inner container into a high-pressure kettle, sealing, carrying out high-temperature reaction for 72 hours in a drying oven at 90 DEG C, separating out a light blue product by using a centrifugal machine after the reaction is completed, washing for multiple times by using water, drying, mixing the obtained light blue powder with PET slices, melting and granulating, and drying to obtain the PET composite material. The preparation method comprises the following steps: preparing a bio-enzyme coated with a metal frame, mixing the bio-enzyme coated with the metal frame with common polyester chips, carrying out melt spinning to prepare multifunctional polyester fibers containing the bio-enzyme coated with the metal frame, taking the polyester fibers as weft yarns and cotton fibers as warp yarns, and interweaving into gray fabric according to a certain rule, so that the problem that the existing antibacterial anti-mite fabric is poor in effect durability is solved.
