Said Non-woven fabric This product many friends are not unfamiliar, this is because with the Non-woven industry research and development, non-woven fabric has become our daily use of a product, for example, in the city people in the life of the most use of handbags, especially in the agricultural vegetables grown greenhouse vegetable greenhouses insulation is, its main material is made with needle-free non-woven fabric processing. Fire-retardant Nonwoven Fabric Greenhouse insulation material in winter greenhouses is from the grass to the large shed heat preservation, but there is a flaw is the lack of fire function. With the birth of flame-retardant non-woven fabric, it is very good to solve the problem of fire protection of vegetable greenhouses and greenhouses. I would like to introduce to you the flame retardant non-woven fabric principle.
Flame-Retardant Nonwoven fabric is more resistant to high temperature than other non-woven fabrics, and its melting point is higher and its sealing property is better. Fire-retardant Nonwoven Fabric So why is the flame-retardant Non-woven fabric? Small series for you to tell the two points, the first is the fiber additives, followed by the non-woven surface coating flame retardant agent.
First, it is the flame retardant function of the flame retardant agent through polymer polymerization, blending, copolymerization, composite spinning, technical modification, etc. Fire-retardant Nonwoven Fabric into the fiber, so that the fiber has flame-retardant.
Second, after finishing the flame retardant coating on the surface of the fabric or infiltration into the fabric. These two ways give the fabric flame-retardant link different, the effect also has the difference. At present, Fire-retardant Nonwoven Fabric the best way is to use nano-materials and nanotechnology to modify the textile processing, low cost, the effect of continuous, and the softness of the textile feel and feel unchanged, reached the international first-class level.
Jinan Zhangqiu Non-woven Fabric Co., Ltd. said, overall, fiber flame retardant than fabric flame retardant more fully use, its effect is more durable, feel more soft. However, Fire-retardant Nonwoven Fabric in practical application, a variety of flame retardants are used, and the synergistic effect is achieved by two or more kinds of methods.
Flame retardant Non-woven Fabrics classified by material:
(a) According to their main composition, can be divided into: Polyester flame-retardant Non-woven fabric, pp flame-retardant non-woven fabric and viscose-flame-retardant Non-woven fabric three mark.
1, Polyester flame-retardant Non-woven fabric is the main ingredient is polyester, polyester fiber belongs to the chemical fiber, is terephthalic acid or terephthalic acid diethyl ester and ethylene glycol polymerization products.
Features: High strength, good elasticity, good heat resistance, Fire-retardant Nonwoven Fabric smooth surface, good wear resistance, good light resistance, corrosion resistance and poor dyeing.
2. Polypropylene fiber is a synthetic fiber made from propylene.
Features: High strength, wet strength and good dry strength, abrasion resistance, corrosion resistance.
3. Viscose fibers belong to regenerated cellulose fiber
Features: good moisture absorption, fracture strength than cotton small, environmental protection, non-toxic.
(ii) flame-retardant Non-woven fabric According to the process can be divided into flame-retardant needle cotton and flame-retardant hot-air cotton.
Flame-Retardant needle cotton is the fiber tangled after puncture by the needle machine
Flame-Retardant hot-air cotton is mainly formed after the hot-blast furnace.
Both products have their own characteristics, common is flame-retardant fire, light, warm, durable, environmental protection.
Test standards include the American 16c Fr163, the British BS5852 and the American TB117, the CA133 standard.
