Marka hore, Polyester (PET) spunbond filament maro aan-dhoobo ahayn waa maro aan tol lahayn oo biyaha celinaysa, iyo wax-qabadka biyaha ee ka-hortagga dharka aan timaha ahayn waa ka duwan yahay miisaanka garaam. Miisaanka garaamku wuu weyn yahay oo dhumucdiisuna way sii fiicnaanaysaa ka hortagga biyaha. Haddii ay jiraan dhibco biyo ah oo ku yaal dusha sare ee marada aan timaha lahayn, dhibcaha biyuhu waxay si toos ah uga soo qulquli doonaan dusha sare.

Labaad, iska caabin heerkul sare ah. Sababtoo ah barta dhalaalaysa ee polyesterku waxay ku dhowdahay 260 ° C, waxay ilaalin kartaa xasilloonida dharka aan timaha lahayn ee deegaanka halkaasoo looga baahan yahay caabbinta heerkulka. Waxaa si weyn loogu isticmaalay daabacaadda wareejinta kulaylka, shaandhaynta saliidda gudbinta, iyo qaar ka mid ah walxaha isku dhafan ee u baahan iska caabin heerkul sare ah.

Seddexaad, polyester (PET) spunbond maro aan- ton ahayn waa fiilo maro aan tol lahayn oo labaad oo keliya marka loo eego naylon spunbond maro aan tol lahayn. Awoodeeda aadka u wanaagsan, xajinta hawada wanaagsan, adkaysiga iyo jeexjeexa iska caabinta iyo guryaha ka hortagga gabowga ayaa dad aad u tiro badan u adeegsadeen meelo kala duwan. 

Midda afraad, polyester (PET) spunbond maro-dhoobo ah ayaa sidoo kale leh hanti jireed oo gaar ah: caabbinta fallaadhaha gamma. Taas macnaheedu waa, haddii lagu dabaqo alaabta caafimaadka, waxaa si toos ah loogu jeermi karaa fallaadhaha gamma iyada oo aan la baabi'in hantideeda jireed iyo xasilloonida cabbirka, taas oo ah sifooyinka jireed ee polypropylene (PP) spunbond ee dharka aan duubnayn.
