Abstract

The invention relates to nonwovens containing antibacterial and antiviral master batches and a method and device for producing the same. The nonwovens comprise 3-5% of antibacterial and antiviral master batches and 95-97% of polypropylene by weight, wherein the antibacterial and antiviral master batches comprise 40-55% of silica-coated tourmaline and titanium dioxide particle composite antibacterial materials and 45-60% of polypropylene by weight. By adding the antibacterial and antiviral master batches in the process of producing the melt-blown nonwovens, the prepared nonwovens have efficient antibacterial and antiviral properties and can prevent diseases and protect human skins and conduce to health care.

Description

technical field [0001] The invention relates to a non-woven fabric and its production method and device, in particular to a non-woven fabric containing antibacterial and antiviral master grains and its production method and device. Background technique [0002] Non-woven fabric is a modern new material industry with high technical content, wide market demand, wide scope, beyond imagination and unlimited development in the flexible material production system. It is developing at an astonishing speed and is known as the "" uprising industry". Although non-woven fabrics produced by different processes have superior effects in improving the hygienic environment and facilitating use. However, human skin and clothes are places where bacteria breed. These bacteria use urea and other human excrement in sweat as a source of nutrition, continuously reproduce, and emit ammonia with a strong odor. Especially in hospitals, stations, shopping malls, cinemas, public transport vehicles an...
