1. Over-cool protective clothing:
Undercooled protective clothing requires high insulation, small size, good comfort and sport sensitivity. The still air is a poor conductor of heat. In addition, the best insulating medium can also be used to increase the static insulating air content in various filled fibers or high loft materials by using fluff and goose feathers and other poultry feathers, or by simulating the design of natural animals. In the market, 3M's Thinsulate and Albany International Primaloft, which are blended with coarse fiber, conventional fiber and fine fiber, absorb less than 1% of their moisture, making it warmer than wet products. It’s better; a multi-layer synthetic garment designed by Arthur D Little in the United States for use in the Antarctic. It used to be a polyester fluffy underwear with a stalked water finish. The middle layer is a brush-like high-fluffy polyester fluff insulation layer. The layer is a waterproof and windproof PTFE (polytetrafluoroethylene) coated aramid knit fabric. However, such garments cannot be treated by the washing and ironing method of ordinary clothing.
2, bulletproof, anti-mechanical clothing:
This is a type of body armor protective clothing, mainly used for bulletproof, cut-proof, anti-saw, anti-thin metal, glass, knife or other sharp edge objects. The replacement of nylon by Kevlar has been a major advancement in this field. In the field of soft armor, aramid multilayer stacking can be used to provide further bulletproof and stab protection. At present, Allied's Spectra Shield uses Spectra ultra-high strength polyethylene fiber polyester composite sheet, which is 1/3 lighter than Kevlar, and its 23-layer composite provides the same level of protection as the 30-layer Kevlar composite. The Spectra Shield can't be used at temperatures up to 200 degrees Fahrenheit, but the material's thermoformability is ideal for a variety of shapes. Mechanical protection products such as cut-proof include protective gloves made of para-aramid, baffles, sleeves, and anti-saw felts. The leggings can be made of asymmetrical aramid or coarse nylon yarn and fiber synthetic needle felt, or a combination of needle felt and woven material, which can be entangled with the electric sawtooth to stop it and prevent serious damage to the body.
3, radiation protective clothing:
Most garments can have a certain role in preventing foreign substances from entering and isolating the skin and harmful substances, but the protection of the rays requires special copolymer coatings, such as the commonly used polyethylene coating Tyvek, used in nuclear plants, high voltage electricity. Now in an electronic device and in an X-ray environment. The Savannah River Site Plutonium plant in the United States uses this special anti-Tritium protective clothing on both sides of the polyester material. The coating material is CPE/EVA/PVDC (Saran)/EVA copolymer. The uniform is made of Saran/CPE coating material or inorganic cloth material which is not made of cloth. Japan uses polyethylene-coated boron fiber to produce radiation protective clothing, and can also add lead in the fiber to improve the level of protection for X-ray environment.
4. Protective clothing for harmful particles:
This protective suit is used for protective clothing in the field of lead dust, spraying or similarly designed micro-hazardous materials. These garments are usually made of non-manufactured materials, but also woven polyester-cotton blends, cotton or coated materials. . There are three standard fabrics in the United States: uncoated Tyvek; Kimberly Clark's 3-layer spunbond-meltblown-spun-bonded Olefin fabric Kleen Guard; hybrid non-manufactured materials such as spunbond Olefins. These products are usually used at one time, and the main problem at present is to improve the wearing comfort, so that the sweat from the body can be emitted through the clothing.
5. Microbial/bacterial protective clothing:
Medical protective clothing is mainly used to protect against the spread of life-threatening viruses. The composite copolymer coated woven fabric and non-manufactured fabric protective material can be used as protective clothing fabrics for medical personnel, emergency personnel and police officers after antibacterial finishing. Dupont's Biowear material can be used for the protection of blood bacteria. The Japanese product Bactekiller (Kanebo) is a bactericide added to the spinning solution. The bactericide is mainly silicate, which acts when the outside is wet.
6. Chemical protective clothing:
Protective clothing for chemical protection is divided into A_??D according to the degree of protection, A and provides the highest protection, integral sealing, containing breathing equipment to prevent chemical gases and vapors; B and similar to Class A, for protection Splashes of toxic chemicals, but not fully sealed; Class C provides protection against chemical splashing, may not require a respirator; Class D provides only less protection. Ordinary or coated Tyvek spunbonded Olefin fabrics are the most commonly used chemical protective clothing fabrics. Higher levels of protection are achieved with Tyvek coated Saranex23P, a Dow chemical plant that is a multi-layer protective coating material. The layer is low density polyethylene with a copolymer of vinylidene chloride and a layer of vinyl acetate (EVA) bonded to Tyvek. In addition, some manufacturers have developed polyester and Olefin spunbond or velvet non-manufactured fabrics for less than $1,000. The more durable garments are made of nylon, polyester or nylon/polyester blend fabrics, coated with polymers such as Teflon PTFE (Dupont), butyl EDPM, Viton (Dupont), etc., and can be used as Class A protective clothing.
7, thermal protective clothing:
The development of new high-tech heat-resistant fibers such as Nomex, PBI, Kermel, P84, pre-oxidized Pan fibers, and the development of cotton and blended fibers after fire protection provide a good basis for the production of such protective clothing. For firefighters, the outer layer is usually a Nomex, Kevlar or Kevlar/PBI blended woven material with an areal density of 254.6 g per square meter and (7.5 ounces per square yard) of twill, providing primary fire protection and wear resistance. There is a Teflon-coated waterproof layer under the outer layer, which is waterproof and enters the inside of the garment to produce hot steam to prevent hot pressing. Under the waterproof layer is a layer of lining to increase the static air content and improve the thermal insulation. The material is Nomex needle felt or high loft material.
