Meltblown nonwovenqiimaha waa dhexdhexaad, halka waxqabadka iska caabin aad u fiican oo loogu talagalay hydrolysis iyo daxalka aashitada iyo alkali, oo inta badan loo isticmaalo shuruudaha heerkulka aysan sarreyn, qoyaanku waa xaalado shaqo oo waaweyn.
Guud ahaan, iska caabbinta heerkulka ee fiilada polyester-ka waxay u dhaxaysaa 130℃ iyo 150℃. Si looga gudbo ifafaalaha yaraanta ee dareemaha irbadda polyester-ka caadiga ah kaas oo leh iska caabbinta heerkulka in ka badan 130℃ muddo dheer, shaandhada cusub ee la dareemay heerkul shaqeynaya oo ah 150℃ ~ 170℃ ayaa la sameeyay, si looga fogaado qashinka ka dhasha isticmaalka walxaha shaandhada heerkulka sare leh xaaladaha shaqada qaarkood.
Dareeraha irbadda leh wuxuu hagaajiyaa saxnaanta shaandhaynta ee walxaha shaandhada fiilada polyester-ka wuxuuna yareeyaa hoos u dhaca cadaadiska, wuxuuna leeyahay saameynta shaandhaynta dusha sare ee walxaha shaandhada dahaaran. Taxanaha shaandhooyinka heerkulka dhexdhexaadka ah iyo kuwa caadiga ah, dareemaha irbadda polypropylene wuxuu leeyahay iska caabin heerkulka ugu hooseeya, iska caabinta socodka oo hooseeya wuxuuna keydiyaa tamarta. Marka lagu daro faa'iidooyinka shaandhada dareemaha caadiga ah, iska caabinta xirashada aad bay u fiican tahay, iyadoo leh saamiga kharashka sare waxayna noqotaa tirada ugu badan ee noocyada shaandhada dareemaha.
Heerkulka dareeraha acupuncture-ka ee loo yaqaan 'acrylic fiber acupuncture' waa 140 ~ 160 digrii Celsius, isticmaalka wax soo saarka fiber-ka ee la soo dhoofiyo, waa iska caabbinta ugu fiican ee aashitada, alkali iyo hydrolysis-ka walxaha shaandhada heerkulka dhexdhexaadka ah.
Waxaan ku takhasusay soo saarista meltblown nonwoven, soo dhawoow inaad la tashato ~
