What is Protective Clothing Materials?

The non-woven materials used in several medical protective clothing currently being sold and developed in the domestic market mainly include the following types.

1. Polypropylene spunbond fabric.

Polypropylene spunbond fabric can be treated with antibacterial and antistatic to make antibacterial protective clothing, antistatic protective clothing, etc. Compared with traditional cotton protective clothing, polypropylene spunbond microporous coverall is undoubtedly a big improvement. Because of its low price and one-time use, it can greatly reduce the cross-infection rate. It has been widely promoted in foreign countries for a long time since its launch. However, the material has relatively low anti-hydrostatic pressure and relatively poor blocking efficiency of virus particles, and can only be used as ordinary protective equipment such as sterile surgical gowns and disinfection wraps.

2. Spunlace cloth made of polyester fiber and wood pulp.

The material feels soft, close to traditional textiles, and can be treated with three antibodies (anti-alcohol, anti-blood, and anti-oil), anti-static, anti-bacterial, etc., and can be sterilized with gamma rays. It is a relatively good medical protective clothing material. However, its anti-hydrostatic pressure is relatively low, and the efficiency of blocking virus particles is also relatively poor, so it is not an ideal protective clothing material.

3. Polypropylene spunbond-meltblown-spunbond composite nonwoven fabric, the SMS microporous coverall.

Meltblown cloth is characterized by small fiber diameter, large specific surface area, fluffy, soft, good drape, low filtration resistance, high filtration efficiency, strong hydrostatic pressure resistance, but low strength and poor wear resistance, which is quite limited The development of its application field. The spunbond fiber has a higher linear density, and the fiber web is composed of continuous filaments. Its breaking strength and elongation are much larger than that of meltblown fabrics, which can just make up for the deficiencies of meltblown fabrics.
