The textile industry is an important pillar industry of the national economy. After a long period of technological innovation and industrial transformation, especially with the rapid development of non-woven technology, the application field and scope of industrial textiles have continued to expand, which has played a role in this epidemic. Important role.

This article mainly describes the application of industrial textiles from three areas of public concern, such as isolation protection, personal hygiene cleaning, and temporary hospital construction.

1.Medical masks

Masks are essential for medical personnel to treat patients and people during daily outbreak protection in this epidemic. At present, China's medical masks are mainly divided into three types: medical protective masks with the highest protection level, medical surgical masks commonly used in invasive operating environments such as operating rooms, and general Grade of disposable medical masks. The raw materials of these medical masks are mostly polypropylene, and the structure is generally composed of multilayer nonwoven materials. The most common is the SMS structure (spunbond-meltblown-spunbond). The meltblown nonwoven material in the middle layer has a good quality. Virus filtering.

2.Medical protective clothing

Medical protective clothing can effectively block the invasion of bacteria and viruses, which is of great significance for protecting the safety of medical staff and workers in public places. Most current medical protective clothing also uses non-woven fabrics as the main raw materials. Commonly used on the market are polypropylene spunbond, polyester fiber and wood pulp composite spunlace, polypropylene SMS nonwovens, and some nonwovens. Composite materials, etc.

3. Medical disinfection alcohol tablets

The base material of medical disinfection alcohol tablets is non-woven material, and the processing technology is mostly spunlace. The raw materials used can be viscose fiber, polyester fiber, polyethylene or polypropylene. After adding alcohol to the product, it has the characteristics of cleanliness, antibacterial, fast liquid absorption, strong liquid retention, and high mechanical strength required for medical and hygienic materials. It can be used for disinfection before injection and emergency surgery; it can also be used for household products, Cleaning and disinfection of toys, etc.

4, disinfection wipes

Disinfection wipes have the characteristics of being easy to carry and use, and can play a cleaning and disinfecting role in people's return protection. Disinfection wipes are generally made of spunlace nonwoven material as a base cloth, and suitable materials such as disinfectants are added to make products that have cleaning and disinfecting effects. They have good skin-friendly effects and disinfecting effects. They can be used for cleaning hands and public when people travel. Place armrests, seat wipes, etc.

5, geomembrane

During the construction of Vulcan Mountain Hospital, the foundation impervious layer used a structure of "20cm sand cushion + polypropylene filament non-woven geotextile + HDPE geomembrane + polypropylene filament non-woven geotextile + sand cushion" , Which is often referred to as the "two cloths and one membrane" structure. It is formed by heating the two sides of the geomembrane through the oven's far infrared, and the nonwoven geotextile and geomembrane are pressed together by the casting method or by the guide roller. It has low density, good extensibility, strong ability to adapt to deformation, resistance to Corrosion and other advantages. Among them, the non-woven geotextile can block the sharp particles in the soil and protect the geomembrane.
