Choyamba, polyester (PET) spunbond filament yopanda nsalu ndi nsalu yopanda madzi yopanda madzi, ndipo ntchito yopanda madzi ya nsalu zopanda nsalu ndizosiyana malinga ndi kulemera kwa gramu. Kukula ndi kukhuthala kulemera kwa gramu, kumapangitsanso kuti madzi asamalowe. Ngati pali madontho amadzi pamwamba pa nsalu yopanda nsalu, madontho amadzi amatsetsereka kuchokera pamwamba.

Chachiwiri, kukana kutentha kwakukulu. Chifukwa malo osungunuka a polyester ali pafupi ndi 260 ° C, amatha kusunga bata la nsalu yopanda nsalu m'malo omwe kutentha kumafunika. Zakhala zikugwiritsidwa ntchito kwambiri pakusindikiza kutengera kutentha, kusefera kwamafuta, ndi zinthu zina zophatikizika zomwe zimafuna kukana kutentha kwambiri.

Chachitatu, nsalu ya poliyesitala (PET) ya spunbond yosalukidwa ndi nsalu yopanda ulusi yachiwiri kwa nayiloni spunbond yopanda nsalu. Mphamvu zake zabwino kwambiri, kutulutsa mpweya wabwino, kulimba mtima komanso kugwetsa misozi komanso zinthu zotsutsana ndi ukalamba zagwiritsidwa ntchito ndi anthu ochulukirapo m'magawo osiyanasiyana. 

Chachinayi, nsalu za polyester (PET) za spunbond zosalukidwa zilinso ndi chinthu chapadera kwambiri: kukana kuwala kwa gamma. Ndiko kunena kuti, ngati itagwiritsidwa ntchito pazachipatala, imatha kuyimitsidwa mwachindunji ndi kuwala kwa gamma popanda kuwononga mawonekedwe ake akuthupi ndi kukhazikika kwake, zomwe ndizinthu zakuthupi zomwe polypropylene (PP) spunbond yopanda nsalu zilibe.
