The invention discloses a
processing technology of needle-punched non-
woven fabric. According to the
processing technology of the needle-punched non-
woven fabric, high-strength inflaming retarding
polypropylene fibers and inflaming retarding
polyester fibers are used as raw materials. The
processing technology comprises the steps of unpacking, material mixing, opening, cotton feeding,
carding, lapping, drafting, needle
punching, hot rolling and coiling. According to the mode, professional equipment and adjustment are utilized for guaranteeing the uniformity and the thickness of lapping of the fibers, cloth with uniform longitudinal and transverse
fiber networks is formed by accurate needle
punching of three needle
punching machines, and the formed non-
woven fabric is soft in hand feel, high in strength, small in
ductility, light in weight and resistant to abrasion, acid and alkali; due to the fact that stretching resistance and tearing resistance in the longitudinal direction and the transverse direction are improved greatly, the non-woven fabric is good in
water washing and
dry cleaning effect; meanwhile, due to the waterproof, fireproof, non-toxic and environment-friendly characteristics, the non-woven fabric is widely applicable to the fields of soft sofas, home decoration, car seats, interior trim and the like.
