The role of medical protective clothing is to produce a bacterial barrier layer to prevent bacterial migration and reduce cross-infection. In recent years, some scientific research institutes and enterprises have developed many medical protective clothing, most of which are made of non-woven fabrics. Medical protective clothing can be divided into woven materials, non-woven materials and composite materials according to the fabric structure. According to the service life, it can be divided into one-time (one-time), limited type and reusable type. According to the processing and compounding process, there are three methods: finishing, coating and laminating
Protective clothing has different properties due to the use of different raw materials. At present, the following non-woven materials are mainly used in several medical protective clothing currently sold and developed in the domestic market.
polypropylene spunbonded cloth
Polypropylene spunbonded cloth can be made into antibacterial protective clothing and antistatic protective clothing through antibacterial and antistatic treatment. Compared with traditional cotton protective clothing, polypropylene spunbonded protective clothing is undoubtedly a great progress. Due to its low price and one-time use, it can greatly reduce the cross-infection rate and has been widely promoted abroad for a long time. However, the material has relatively low hydrostatic pressure resistance and relatively poor barrier efficiency to virus particles, and can only be used as ordinary protective equipment, such as sterile surgical gowns, disinfection cloths, etc. By
Spunlace fabric made of polyester fiber and wood pulp
The hand is soft, close to traditional textiles, can be treated with three kinds of resistance, such as alcohol resistance, blood resistance, oil resistance, antistatic and antibacterial, and can be sterilized by gamma rays. It is a good medical protective clothing material. However, its hydrostatic resistance is relatively low, and its barrier efficiency to virus particles is relatively poor, so it is not an ideal protective clothing material.
Polypropylene Spunbond-Meltblown-Spunbond Composite Nonwovens, namely SMS or smms
Meltblown fabrics have the characteristics of fine fiber diameter, large specific surface area, fluffy and soft, good drape, low filtration resistance, high filtration efficiency, strong hydrostatic pressure resistance, but low strength and poor wear resistance. However, spunbond fabrics have high linear density, and the fabric is composed of continuous filaments. Its breaking strength and elongation are much greater than those of meltblown fabrics, which can only make up for the shortcomings of meltblown fabrics. The material has the following excellent characteristics:
① Uniform and beautiful appearance;
② High static pressure resistance;
③ feel soft;
④ Good air permeability;
⑤ Good filtering effect;
⑥ Strong acid and strong alkali
In addition, the SMS non-woven fabric can also be three kinds of anti-static (anti-alcohol, anti-blood, anti-oil) and anti-static, anti-bacterial, anti-aging treatment to meet the needs of different uses.
polymer coated fabric
Protective fabrics used in a variety of coatings, including polyvinyl chloride, polyethylene, polychloroprene rubber and other synthetic rubbers. This kind of protective clothing has good water resistance and bacterial particle blocking properties, and can be reused, but the moisture permeability is poor, a large amount of sweat cannot be discharged from the human body, and the wearing comfort is poor. The use of rubber-coated fabric protective clothing during the SARS period was indeed a last resort. The latest development at home and abroad is to use microporous PTFE film and fabric to obtain waterproof and breathable function, but it is expensive as a disposable product
Polyethylene Breathable Film/Nonwoven Composite Fabric
According to the requirements of different protection levels, the non-woven fabrics and films used are also different. Polyethylene breathable film/non-woven fabric composite material has excellent effect of blocking bacterial particle penetration and liquid penetration. It can adjust the hand feeling by changing the softness of the composite material. It has strong tensile strength, good air permeability, and greatly improved comfort. It can be disinfected, does not contain toxic ingredients, weighs 60-100g/m2, and has good cost performance. Medical disposable protective clothing made of polyethylene breathable film/non-woven fabric composite material can protect medical personnel from pollution sources, overcome cross-infection, play an effective protective role.
