Said that non-woven fabrics this product is no stranger to a lot of friends, this is because with the non-woven industry research and development, nonwovens has become our daily life often used a product, for example, people in the city In the most use of the bag, especially in the agricultural vegetable planting greenhouse greenhouse insulation, the main material is made of acupuncture non-woven processing. Winter greenhouse greenhouse insulation material is from the grass to the transition to the greenhouse insulation, Fire-retardant Nonwoven Fabric but there is a flaw is the lack of fire function. With the birth of fire-retardant non-woven fabrics, a good solution to the greenhouses and green shed greenhouse fire. Here I would like to tell you about the flame retardant non-woven flame retardant principle.
Flame-retardant non-woven fabric is more resistant to high temperature, compared with other non-woven fabric, its melting point is higher, better sealing. So why is the flame-retardant non-woven flame retardant? Xiao Bian simple for you about two points, first Is the fiber in the additive, followed by non-woven fabric coated flame retardant.
First, the flame retardant function of the flame retardant by polymer polymerization, blending, copolymerization, composite spinning, technology modification, etc. Fire-retardant Nonwoven Fabric added to the fiber, the fiber has a flame retardant.
Second, the use of finishing method will be flame retardant coating on the surface of the fabric or into the fabric inside the two ways to give the fabric fire-retardant links are different, Fire-retardant Nonwoven Fabric the effect is also different.Currently the best way is to nano-materials And nano-technology for textile modification, low cost, the effect is sustained, and the soft feeling of the textiles and feel did not change, reached a world-class level.
Flame-retardant non-woven fabrics by material classification:
(A) according to their main components can be divided into: polyester flame retardant non-woven fabrics, polypropylene flame retardant non-woven fabrics and viscose flame retardant non-woven fabrics.
1, polyester flame retardant non-woven fabric is the main component of polyester, polyester fiber is a chemical fiber, is terephthalic acid or diethyl terephthalate and ethylene glycol polymerization products.
Features: high strength, good elasticity, good heat resistance, smooth surface, good wear resistance, good light resistance, corrosion resistance, poor dyeing.
2, polypropylene fiber is made of propylene as raw materials of synthetic fibers
Features: high strength, wet strength and dry strength, wear resistance, corrosion resistance.
3, viscose fiber is recycled cellulose fiber
Features: with good hygroscopicity, breaking strength than cotton small, Fire-retardant Nonwoven Fabric environmentally friendly, non-toxic.
(B) flame retardant non-woven fabrics can be divided into flame-retardant cotton and fire-retardant hot cotton.
Flame retardant needle cotton is punctured by the needle after the tangled fiber
Flame retardant hot air cotton is mainly after the network after the formation of hot air furnace.
Fire-retardant Nonwoven Fabric Both products have their own characteristics, common fire retardant, lightweight, warm, durable, environmentally friendly.
Test standards are the United States 16CFR1633, the British BS5852 and the United States TB117, CA133 standard.
