The importance of flame retardant protection in the new era

Flame retardant textiles for national defense and military industry, This also provides a platform for providing more cost-effective military textiles. As far as flame retardant products are concerned, chemical flame retardant fibers mainly include Aramid 1313, aramid 1414, heterocyclic aramid, polysulfonamide, carbon fiber and vinylon. Flame retardant fiber as an intermediate product is mainly used in protective clothing, anti-G clothing, compensatory clothing and other fields. The requirements and trends of anti-G clothing and compensatory clothing for textile materials are mainly reflected in light weight, aging resistance, good strength, easy dyeing, flame retardant, waterproof and breathable properties. 1t is worth mentioning that the textile coating and outer material of Shenzhou V11 spacesuit have made a breakthrough in high temperature resistance, radiation resistance and other indicators. The protective material has the properties of tear resistance, wear resistance, thermal radiation resistance, micro meteor resistance, chemical corrosion resistance and ion radiation resistance

the application fields of flame retardant fiber in parachute generally include: parachute jacket, parachute rope, lifting strap and parachute jacket. 1n a complete parachute, except that some buttons and pull rings are made of metal, others are made of flame retardant composite fiber. With the improvement of military science and technology strength, parachute has higher and higher requirements for textile materials, which are mainly reflected in: light weight, high strength, aging resistance, flame retardant, anti burning, antistatic, stable shape, good breaking strength and anti tearing strength; 1t can adapt to different air permeability; One way extension can be implemented within the design scope according to the specific use

in addition to some special clothing, flame-retardant fiber is also used in barrier net, artillery suit, aircraft cloth, tent, camouflage net, etc. among them, chameleon, a camouflage material developed by the sixth room of a certain 1nstitute of the Second Artillery Equipment Research 1nstitute, is mainly composed of flame-retardant composite fiber

textile flame retardant finishing technology and product development

generally, fabric combustion can be divided into three stages, namely thermal decomposition, thermal ignition and thermal ignition, All kinds of flame retardant mechanism and interruption flame retardant mechanism are formed. According to the existing research results, the flame retardant mechanism can be roughly divided into endothermic reaction, free radical formation, melting theory, non combustible gas formation, condensed phase flame retardant and so on

according to the type of flame retardant compounds, including inorganic flame retardant, which can not only play the role of flame retardant, but also play the role of filling. Organic flame retardants can be divided into phosphorus series and halogen series. The former is very limited in use. Halogenated flame retardants mainly include chlorine and bromine

flame retardant fibers are mainly produced by coating method, blending method, copolymerization method, grafting modification method and skin core composite spinning method. The processing technology of fabric flame retardant finishing mainly includes dip rolling, baking, drying, coating, spraying and organic solvent. Br / >
with the increasing sales of motor cars, high-speed trains and cars, the market for high-end interior flame retardant fabrics is also increasing, among which each motor car needs about 1000 meters seat fabric; Each car needs about 20 meters of textile, and more than 80 parts are designed

in 2007, high-end automotive interior textiles need to have the characteristics of flame retardant, moisture absorption, air permeability, high color fastness, sun resistance, anti-static, anti falling wool, etc., which are higher than those of clothing textiles. However, China’s development capacity is weak, mainly with the introduction of complete sets of technology, and high-end products are monopolized by Japan and European countries. The technical difficulties mainly include the heavy smoke caused by the large amount of existing flame retardant, the heat resistance of finished fabric, the high temperature viscosity, the prominent problems of smoke density, smoke toxicity and droplet

for this purpose, we developed and designed P-T intumescent flame retardant, which is formaldehyde free, halogen-free, good thermal and hydrolysis stability, high melting point and low moisture absorption. The flame retardancy and safety of high-speed train seat fabric with this flame retardant have passed the American FRA standard, French NF standard, British BS standard and German D1N standard, and have been successfully applied to French long-distance passenger, Japanese Qingdao Sifang, Siemens, etc

why should we use protective clothing

Geoff, the personal protection expert of European famous Fiber Company

the correct selection and use of flame retardant protective clothing can reduce catastrophic clothing fire and save lives. Compared with the cost of rehabilitation treatment in hospital after burn, the cost of protective clothing is minimal and the most effective. 1f the operator is wearing the wrong clothes, the skin burn will be more serious in the place where the clothes are worn than in the exposed place

nowadays, more and more countries have enacted mandatory laws to require workers in dangerous situations to be equipped with appropriate personal protective equipment. Many multinational companies, such as Petronas, shell and Alcoa, have implemented the policy of wearing personal protective equipment. Their regular employees and contract employees are required to use personal protective equipment. China has also adopted or ordered workers to wear personal protective equipment in many industrial fields

it is estimated that every 1% of skin burn patients need to be hospitalized for 1.5 days, with an average of 19 days, and the daily cost is more than 18000 US dollars. The total cost of hospitalization is between $200000 and $700000, often more than $1 million

the flame retardant property is that when the flame leaves the fabric, the fabric will automatically extinguish. Flame retardant finishing is to carry out the corresponding flame retardant finishing on the fabric, so that it has the self extinguishing performance after the flame leaves. Flame retardant is used in finishing fabric to make it have flame retardant effect, but some fabrics will remain formaldehyde and other toxic substances, and the flame retardant has been taken away in the daily washing process. The intrinsic flame retardant fabric, such as aramid fiber, cellulose fiber and so on, has flame retardant properties, and the flame retardant effect will not decrease with the increase of washing times

the requirements of flame retardant test include: vertical combustion test, 12 second flame combustion, damaged carbon length less than 6 inches, and continuous combustion time less than 2 seconds. Wearing the right flame retardant protective clothing will reduce injuries. The future industrial areas of purchasing protective clothing include: power grid and natural gas enterprises, steel plants, fire rescue, etc
