Polypropylene spun-bonded non-woven fabrics is when making sanitary material and using, its feel is comparatively hard, and comfort level is lower, generally needs to carry out mellowing, its mellowing is generally added by master batch or the method for Final finishing is carried out, and by reducing interfibrous frictional coefficient, the pliability of non-woven fabrics is improved.
By Final finishing or master batch modification, polypropylene spun-bonded non-woven fabrics can obtain good flexibility, but its pliability is still lower than polyethylene spun-bonded non-woven fabrics, and its technical process is simultaneously complicated or cost increase is more.
Compared with polypropylene, carry out as raw material according to polyethylene, product can have more excellent flexibility and ageing-resistant performance.But because polyethylene molecule is long for time of relaxation, easily produce fracture of wire when melting spinning, too, required equipment is complicated for its spinning difficulty.
Current conventional polyvinyl resin, because its molecular chain is long for time of relaxation, crystallization rate is high, and cooling is fast, can not be used for producing spun-bonded non-woven fabrics.
Reason is: although polyethylene is linear molecule, it has good spinning property, but due to its molecular chain oversize for time of relaxation, simultaneously its crystallization rate is high, cooling time is short, easily there is internal cohesive energy fracture when high speed spinning and cause fracture of wire, spinning can not being stablized and carry out.Therefore, the technical difficulty of spun-bonded non-woven fabrics production is carried out with polyethylene large.
