Needle-punched felt non-woven fabric can be divided into three categories according to the material:
Polyester needle-punched flame retardant non-woven fabric, polypropylene needle-punched flame-retardant non-woven fabric and viscose needle-punched flame retardant non-woven fabric. This is mainly divided by their main components.
The main component of polyester needle-punched flame retardant non-woven fabric is polyester, and polyester fiber is a chemical fiber, which is a polymerization product of terephthalic acid or diethyl terephthalate and ethylene glycol.
Features: high strength, good elasticity, good heat resistance, smooth surface, good wear resistance, good light resistance, corrosion resistance, poor dyeability.
Polypropylene needle punched fiber is a synthetic fiber made from propylene
Features: high strength, good wet and dry strength, wear resistance, corrosion resistance.
Viscose needle-punched fibers are newer cellulose fibers
It has the advantages of good hygroscopicity, lower breaking strength than cotton, environmental protection, harmless and degradable.
Flame retardant non-woven fabrics can be divided into flame retardant needle cotton and flame retardant hot air cotton according to the process.
Flame retardant needle cotton is formed by entanglement of fibers after being punctured by acupuncture machine
The flame retardant hot air cotton is mainly formed by hot air passing through the furnace after the net is laid.
Both products have their own characteristics, and the commonality is flame retardant, light, warm, durable and environmentally friendly.
