Tsim cov txheej txheem ntawm polyethylene nonwoven npuag

Kev tsim qauv ntawm polyethylene nonwoven npuag yog qhov sib txawv, tab sis txhua kauj ruam tseem ceeb heev. Ua ntej, cov polyethylene raw khoom yog rhuab rau lub xeev molten. Lub ntsej muag tsw qab zib polyethylene yog tom qab ntawd txau rau hauv filaments los ntawm ib tug spinneret. Cov filaments no yuav ncab thiab txias rau hauv nruab nrab - pa rau ua cov fibers. Tom ntej no, cov fibers yog fawm kib thiab nteg los ua lub vev xaib ntawm ib qho tuab tuab. Thaum kawg, lub vev xaib raug nias rau hauv cov ntaub nonwoven los ntawm cov txheej txheem xws li kub calendering. Thoob plaws hauv cov txheej txheem no, tsis ntsuas xws li kub thiab siab yuav tsum nruj me ntsis tswj kom ntseeg tau tias qhov zoo ntawm nonwoven npuag.
