Flame retardant protective clothing classification and purchase

Flame retardant protective clothing refers to the personal protection products that can make the clothes carbonized to form the isolation layer and slow down the spread of flame after directly receiving flame and hot articles. The quality of the products should meet the requirements of GB8965-88.
     First, the structural design should meet the following requirements:
     1 · Comfortable, lightweight, and beneficial to the body.
     2. The top coat pocket should be covered to prevent splashed molten metal or other dirt from entering the pocket.
     3 · Ventilation pores can be left in the proper place on the top to facilitate air circulation, perspiration and body temperature adjustment. However, the pores must not affect the strength of the garment structure and intrude into the garment interior.
     Second, clothing:
     At a temperature of 60 ℃, the general synthetic detergent, each 15 minutes, after washing 50 times, its flame-retardant properties should meet the requirements. In the test if it is found that the fabric has shrinkage phenomenon is unqualified.
     Third, the suture strength:
     Apparel bonding joints or sewing strength: should be greater than 29.4N.
     Flame retardant protective clothing quality key in the material.
     Fourth, fire-retardant protective clothing products.
     1. Flame-retardant cotton protective clothing: it is made with Pyroatex CP (N-methylol dimethyl phosphonic acid acrylamide) or Proban NX (tetramethylol phosphorus chloride, urea condensate) Flame retardant fabric made of protective clothing. After finishing with Proban NX, it has less damage to the raw materials. The treated fabrics have better flame retardancy, washability and soft feel than the fabrics treated with "CP" flame retardant. Proban NX is a better flame retardant for cotton fabrics. Besides processing 100% cotton fabric, it also handles polyester and cotton and achieves better flame retardancy. Adopting the special finishing process scientifically compounded with cross linking resin and assistant to improve Prroatex CP, the flame retardant and washability are good, and the breaking strength and tearing strength of the material are also in line with the standard of firefighting protective clothing GA-10) requirements. Later, the use of proban flame retardant cloth production technology introduced to develop the FR-101 series flame retardant fabric.
     2. Flame-retardant aluminum film cotton protective clothing: is the use of anti-oxidation of aluminum foil bonding compound method, the surface coating of aluminum powder or aluminum film vacuum aluminum composite technology and other technologies to increase the fabric surface radiation radiant heat performance of the fabric system protective suit. Among them, the flame retarding effect of the fabrics treated by the aluminum foil bonding compound method is better.
     Flame retardant aluminum cotton protective clothing in addition to poor ventilation performance defects, thermal insulation, flame retardant properties, material composite fastness can meet the requirements.
     3. Flame retardant polyester and cotton protective clothing is the use of phosphorus flame retardant, cross-linked resin and other materials to padding baking process finishing polyester-cotton blended fabric protective clothing. Its flame retardancy, washability, resistance to melting, moisture permeability and strength are better.
     4. Flame-retardant high-temperature protective clothing: is made of high temperature flame-retardant fabric protective clothing. There are mainly the following:
     (1) Nomex: It was developed in 1957 by the DuPont Company, has good thermochemical and non-conductive properties, does not melt and flame retardant. In the -40 ~ +200 ℃ range of intensity remained unchanged.
     (2) Kevlar (Kevlar): is a 1968 by the United States DuPont developed a high strength aromatic polyamide fiber, has good thermal stability, flame retardant and does not melt. Softening point of 300 ℃ or more, 300 ℃ when the strong retention rate of 50% to 70%. Due to its high strength, it is also used in the manufacture of bullet-proof vests and helmets, in addition to high-temperature flame-retardant protective clothing.
     (3) polybenzazole fiber: melting point of 560 ℃, at 304 ℃ for 50 hours, the breaking strength remained at 50%; moisture regain exceeded cotton about 11% ~ 13%. Good versatility, can be used for aviation, aerospace and a variety of protective clothing.
     (4) Polysulfonamide fiber: When heated at 300 ° C for 100 hours, the strength is maintained at about 80%, and at 450 ° C only the weight loss is about 10%
     (5) Polysulfonamide: This was developed in China in the early 1980s and its performance is close to that of Nomex fibers. Protective clothing made of heat-resistant fiber fabric, suitable for fire, metallurgical furnaces and other special environments, the price is more expensive.
     Although asbestos fiber, glass fiber and other high temperature flame retardant, but because of poor hygroscopicity, irritating to the skin, are basically not used.
     Flame retardant protective clothing product quality must meet the standards of GB8965-88, according to the requirements of quality inspection, the number of samples for each test 2 sets of each species. After washing 50 times not less than three for the qualified products; a melting shrinkage of substandard products.
Xinxiang City Yulong Textile Co., Ltd. was established in 2002, over the years focused on the production of flame retardant, fluorescent-oriented variety of functional fabrics and security clothing. The company has afunctional fabric factory and protective clothing factory, as the domestic functional textile industry leader, Yu Long textile more groundbreaking integration of its fabric and clothing two factories of the advantages of resources, effort to build functional fabrics and clothing Station service center.
