Codsiga wareejinta fiber-ka polypropylene, ku-dhaqanka wax-soo-saarka polyetylen waa xaddidan yahay. Xariirka jilicsan ee caadiga ah iyo fiilooyinka tayada sare leh, gaar ahaan dhogorta jilicsan sida denier ganaaxa iyo fiilooyinka BCF ee ku habboon laamiga iyo dharka dunta, wax polypropylene ayaa inta badan ka door bida shamac polyetylen.

Ugu horreyntii, sababtoo ah iswaafajinta u dhaxaysa polypropylene iyo polyetylen, aad bay u adagtahay in la sameeyo isku-dhafka isku midka ah ee dareenka microscopic, taas oo horseedi doonta kala-soocidda wajiga. Marka labaad, sababtoo ah barta dhalaalaysa ee polyetylen wax aad ayuu uga hooseeyaa kan polypropylene ama polypropylene, way adagtahay in lala tacaalo sifooyinka kala duwan ee dhalaalka labadan polymer. Sinnaan la'aanta iyo rheology-ga aan habboonayn ee alaabtu waxay horseedi kartaa dhammaadka jebinta habka wareegga. Dhibaatooyinkan soo raaca awgood, sifooyinka dharka jirka ee fiberku way ka sii daraan.
Waqtigaan, waxaa lagama maarmaan ah in la isticmaalo wax polypropylene leh maqaar hooseeya. Maqnaanshaha hoose iyo qoynta wanaagsan awgeed, waxay ku qoysin kartaa midabada waqti gaaban. Intaa waxaa dheer, marka fiber polypropylene la fidsan yahay iyo kulaylka la dhigay, waxaa laga heli karaa heerkulka daaweynta kulaylka (badanaa ku saabsan 130c), kaas oo ku dhex jira kala duwanaanshaha heerkulka dhalaalaysa ee polyetylen.

Sababtoo ah isbeddelka qaabdhismeedka crystalline ee fiber-ka aasaasiga ah ee polypropylene, waxaa la ogaan karaa in dhalada polyetylen ay ka soo baxdo matrix polypropylene ilaa dusha sare ee fiber, mana aha oo kaliya wax saafi ah, laakiin sidoo kale midabka ayaa la keeni doonaa dusha sare.
Ugu dambeyntii, iswaafajinta ka dhexeeya wax polypropylene iyo resin polypropylene waxay ku fiican tahay dhinacyada yaryar iyo makro, waxayna saameyn yar ku leedahay sifooyinka farsamada. Waxaa jira laba nooc oo wax polypropylene ah oo lagu polymerized by metallocene catalytic technology: mid waa homopolymer polypropylene wax, iyo alaabta ceeriin waa propylene; Midda kale waa wax-ka-soo-baxa polypropylene, oo ka samaysan propylene iyo ethylene.
Guud ahaan, wax-soosaarka polypropylene ee homopolymer waxa uu leeyahay meel dhalaalkeedu sareeyo, inta u dhaxaysa 140-160c, culayska kellika ah ee kumanaan ilaa tobanaan kun, oo u dhigma viscosity Brookfield laga bilaabo daraasiin ilaa kumanaan, crystallinity sare iyo adayg sare. Meesha dhalaalaysa ee waxka polypropylene ee copolymer inta badan waa inta u dhaxaysa 80-110c, mawqifka Brookfield waa boqolaal ilaa kun ama xitaa tobanaan kun, miisaanka unugyaduna waa kumanaan ilaa tobanaan kun. Iyadoo ay ugu wacan tahay ku-darka ethylene comonomer ee polypropylene copolymer, taas oo carqaladaynaysa habaynta joogtada ah ee molecules propylene, crystallinity of polypropylene copolymer waa hooseeyaa, sidaas awgeed barta dhalaalku sidoo kale waa hooseeyaa.

Marxaladda qoynta midabka midabka, qoynta wax-soo-saarka viscosity hooseeya ayaa si dhakhso ah u dhacda, waxtarka qoynta ayaa sarreeya. Laakiin waxaa loo baahan yahay in extrusion silig. Marxaladda granulation, waxaan sidoo kale rajeyneynaa in dhuxu leeyahay viscosity gaar ah, kaas oo si fiican u wareejin kara xoogga dhogorta ee u dhexeeya midabka iyo dhalaalka resin, si midabka qoyan uu si siman u qaybiyo dhalaalka resin. Waqtigan xaadirka ah, wax polypropylene leh dhibic dhalaalaysa hoose iyo wax polypropylene leh viscosity sare ayaa la wada isticmaali karaa si loo gaaro kala firidhsan ugu fiican.
