Manufacturing process of household daily anti-microbial non-woven fabric

Abstract

The invention relates to a manufacturing process of household daily anti-microbial non-woven fabric. The manufacturing process is characterized by including the following steps of S1, raw material preparation, wherein a Vistamaxx VM6202 POE elastomer is selected as a main material, a PP material accounting for 4% of the total quantity and nano-silver powder accounting for 0.1% of the total quantity are doped, high polymer slices are manufactured, and the water content of the slices is controlled to be smaller than 4%; S2, feeding and melting, wherein the slices are fed into a screw extruder for melt extrusion, a slipping agent is additionally added into the screw extruder, the length-diameter ratio of the screw extruder is (15-30):1, the temperature of the feeding section is controlled to be 190+ / -10 DEG C, the temperature of the compression section is controlled to be 230+ / -10 DEG C, and the screw speed is 40+ / -10 r / min; S3, filtering and spinning; S4, cooling and drafting; S5, wet formation and prepressing; 6, hot rolling and solidifying; S7, after-finishing, wherein a hot-rolled web is soaked in sol containing nano-silver, each time of soaking is not shorter than 20 min, the web is ultrasonically dispersed for 15 min, and then ultraviolet irradiation is carried out for 10 min; S8, drying; S9, winding.

Description

technical field [0001] The invention belongs to the field of nonwoven fabrics, and in particular relates to a manufacturing process of antibacterial nonwoven fabrics for daily use at home. Background technique [0002] With the development of society and the advancement of technology, consumers pay more and more attention to the environmental protection and health of household products. Many green and environment-friendly household products have appeared on the market, and are liked by consumers in general, such as bamboo fiber products, polylactic acid fiber products, soybean fiber products and the like. Many of these environmentally friendly fiber products are made through the processing technology of non-woven fabrics. [0003] Most of the household cleaning products currently on the market are gauze rags and microfiber rags. The raw material of gauze cloth is natural and environmentally friendly, with good water absorption and oil absorption. The disadvantage is that i...

AI Technical Summary

Problems solved by technology

The raw material of gauze cloth is natural and environmentally friendly, with good water absorption and oil absorption. The disadvantage is that it is easy to hide dirt and mold if it is not dried in time. Microfiber cloth is made of chemical fiber and has poor water absorption, but because it is made of chemical fiber , not very suitable for washing dishes, mostly used for other cleaning purposes

In addition, the antimicrobial properties of the aforementioned gauze wipes as well as the microfiber wipes were insufficient

Although some cleaning products such as rags have been treated with antibacterial agents to achieve antibacterial effects, most of the antibacterial agents used are chemical synthetic agents, and consumers still have concerns about the environmental protection of the products during use

[0004] At the same time, the antibacterial materials at the present stage are all antibacterial additives added to the surface of the cloth to form a coating. Due to long-term use of the coating, the antibacterial effect of the cloth is seriously reduced or even disappears.
