Protective clothing has different properties due to the different raw materials used. At present, the non-woven materials used in several medical protective clothing that are currently being sold and developed in the domestic market are mainly as follows.

Polypropylene spunbond

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 protective clothing is undoubtedly a great improvement. Because of its low price and one-time use, it can greatly reduce the cross-infection rate. It has been widely promoted abroad in a long period of time since its launch. However, the material has relatively low anti-hydrostatic pressure and relatively poor blocking efficiency of virus particles. It can only be used as ordinary protective equipment such as sterile surgical gowns and disinfection wraps.

Spunlace cloth composed 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 disinfected 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.

Polypropylene spunbond-meltblown-spunbond composite nonwoven fabric, namely SMS or SMMS

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 fabric has a relatively high linear density, and the web is composed of continuous filaments. Its breaking strength and elongation are much larger than that of meltblown fabrics, which can make up for the shortcomings of meltblown fabrics. This material has the following excellent characteristics:

① Uniform and beautiful appearance;

② High resistance to hydrostatic pressure;

③ Soft feel;

④ Good air permeability;

⑤ Good filtering effect;

⑥ Strong acid and alkali resistance.

In addition, SMS non-woven fabrics can be treated with three antibodies (anti-alcohol, anti-blood, and anti-oil), anti-static, anti-bacterial, and anti-aging to meet the needs of different uses.

Polymer coated fabric

There are many types of coatings used for protective fabrics, including polyvinyl chloride, polyethylene, polychloroprene rubber and various other synthetic rubbers. This kind of protective clothing has excellent water resistance and bacterial particle barrier performance, and can be reused, but The moisture permeability is poor, a large amount of human sweat cannot be discharged, and the wearing comfort is poor. The use of rubber-coated fabric protective clothing during the SARS period is really a last resort. The latest development at home and abroad is the use of microporous polytetrafluoroethylene film and fabric composite to obtain waterproof and breathable function, but it is expensive as a disposable product.

Polyethylene breathable film/non-woven composite fabric

According to the different requirements of the protection level, the non-woven fabrics and films used are also different. Polyethylene breathable film/nonwoven fabric composite material has excellent effects on blocking bacterial particle penetration and liquid penetration, and the hand feel can be adjusted by changing the softness of the composite fabric. It has strong tensile strength, good air permeability and comfortable performance It is greatly improved, can withstand disinfection, does not contain toxic ingredients, and has a weight of 60~100g/m2. It has a good cost performance. Medical disposable protective clothing made of it can protect medical staff from pollution sources and overcome cross-infection. To the effect of effective protection.
