Abstract

The invention discloses a long-acting anti-acarid, mildew-proof and anti-bacterial PP (Polypropylene) non-woven fabric, which is prepared by carrying out bended spinningon functional master batch and PP; and according to the percentage by weight of the non-woven fabric, the adding amount of the PP is 95-99.9 percent by weight, and the injection quantity of the functional master batch is 0.1-5 percent by weight. The formula of the functional master batch comprises the following components in percentage by weight: 95.50-97.15 percent of PP, 0.25-0.40 percent of zinc pyrithione and 2.60-4.10 percent of low molecular weight polyethylene wax. The preparation method of the non-woven fabric comprises the following steps of mixing the functional master batch by taking the PP as a raw material; and preparing the long-acting anti-acarid, mildew-proof and anti-bacterial PP non-woven fabric through a spunbonding process or a spunbonding-melt spinning-spunbonding process. The long-acting anti-acarid, mildew-proof and anti-bacterial PP non-woven fabric has obvious and long-acting anti-acarid, mildew-proof and anti-bacterial effects, and is non-toxic to the human body and non-irritating to the skin.

Description

technical field [0001] The invention belongs to the technical field of home textiles, and specifically relates to a long-acting anti-mite, anti-mildew and anti-bacterial PP nonwoven fabric and a preparation method thereof. Background technique [0002] At present, in daily life and work, there are many methods of anti-mite, anti-mildew and anti-bacteria, including environmental control, spraying chemicals and using functional textiles. [0003] Environmental control mainly includes maintaining indoor cleanliness and air circulation, reducing dust, regularly cleaning home textiles and air-conditioning equipment, etc.; direct spraying of chemicals is relatively simple to operate, but the effect is not long-lasting, and frequent use will have adverse effects on human health; and Functional textiles are more popular because of their low cost and high efficiency. [0004] According to different production processes and requirements, there are currently several methods for produc...
