Description

Technical Field

[0001] The present application relates to the technical field of pillowcases, and in particular to an antibacterial, anti-mite, sleep-aiding pillowcase and a preparation method thereof. Background Art

[0002] Pillows are one of the indispensable bedding in daily life, which is in direct contact with the head and neck of the human body. Traditional pillowcases are mostly made of cotton, polyester and other materials. Although these materials can provide a certain degree of comfort, they do not have antibacterial function and are prone to accumulate sweat, dandruff and dust mites, becoming a breeding ground for bacteria and fungi. After long-term use, a large number of microorganisms will breed on the pillowcase, which will not only produce odor, but also may cause health problems such as skin diseases and allergic reactions. At the same time, the pillowcase does not have the effect of helping sleep. Based on this, a pillowcase with antibacterial, anti-mite, sleep-aiding, long-lasting deodorizing and washable properties is provided to meet the needs of users. Summary of the invention

Flax fiber has good air permeability and hygroscopicity, which can keep the pillowcase dry and reduce the breeding of bacteria and mites. At the same time, these two fibers also have good warmth retention and antistatic properties, which improves the comfort of the pillowcase. Bamboo charcoal fiber has a super strong adsorption and decomposition ability due to the honeycomb microporous structure running through the inside and outside of the bamboo charcoal fiber and a surface area several times larger than that of charcoal. It can effectively drive away the sweat odor of the human body, and has the functions of antibacterial, regulating humidity and eliminating odor; it also has an adsorption effect on harmful chemicals such as sulfides and nitrides; bamboo charcoal can also produce infrared rays suitable for human absorption, increase blood circulation, and increase the negative ions in the air that are beneficial to health. Far-infrared polyester fiber has far-infrared and negative ion functions, which can improve the microcirculation of the human body, promote metabolism, and help improve sleep quality. At the same time, this fiber also has good flexibility and air permeability, and is suitable for the preparation of pillowcases. Nano-silver cerium doped titanium dioxide and chitosan in the composite antibacterial agent have excellent antibacterial and photocatalytic abilities, can achieve self-cleaning under daily light, decompose organic matter in stains, and maintain the cleanliness of the pillowcase. At the same time, triethanolamine ester quaternary ammonium salt is firmly combined with the pillowcase matrix fiber, making the antibacterial performance more resistant to washing and not easy to fall off. Antistatic agent: helps reduce static electricity and increase comfort. Sleep-aiding composite essential oil: releases mental stress, calms the mind, and improves sleep quality. Anti-mite agent: zinc ions form a connection with metronidazole and water-based acrylic resin to enhance adhesion and continuously prevent mites.

These raw materials form a composite antibacterial agent after a certain preparation method in a reactor. Nano silver cerium doped titanium dioxide and chitosan: have excellent antibacterial and photocatalytic abilities, can effectively kill bacteria and inhibit the breeding of mites. Nano silver cerium and titanium dioxide are combined to produce active oxygen through a photocatalytic process, thereby killing microorganisms.

The combination of zinc nitrate and metronidazole provides a lasting antibacterial and anti-mite effect, effectively prolongs the service life of the pillowcase, and reduces the frequency of replacement. The addition of aqueous acrylic resin improves the dispersion and stability of the anti-mite agent in the pillowcase, maintains the effect of the anti-mite agent, and does not affect the performance of other characteristics of the pillowcase. Through the synergistic effect of the anti-mite agent and the composite antibacterial agent, bacterial growth can be effectively reduced, thereby eliminating odors, providing a lasting deodorizing effect, and keeping the pillowcase fresh.
