Njengoko iPetroChina kunye neSinopec zaqala ukwakha imigca yemveliso yemaski, ukuvelisa kunye nokuthengisa iimaski, wonke umntu ngokuthe ngcembe wafunda ukuba iimaski kunye neoyile zinxibelelene ngokungenakuphikiswa."Ukusuka kwi-oyile ukuya kwiMask" ichaza yonke inkqubo ukusuka kwioyile ukuya kwimaski inyathelo ngenyathelo.Ipropylene inokufumaneka kwi-petroleum distillation kunye nokuqhekeka.Ipropylene ingenziwa i-polymerized ukuze ifumane i-polypropylene, kwaye i-polypropylene inokwenziwa kwakhona ibe yi-polypropylene fiber, into esiyibiza ngokuba yi-polypropylene.Ifayibha yePolypropylene (ipolypropylene) yeyona nto iphambili kwifiber ekrwada ukwenzela ukuveliswa kwamalaphu angalukwanga, kodwa ayisiyiyo yodwa impahla ekrwada.I-polyester fiber (i-polyester), i-polyamide fiber (nylon), i-polyacrylonitrile fiber (i-acrylic fiber), i-viscose fiber, njl.
Kambe ke, ukongezelela kule micu ingasentla yemichiza, imicu yendalo efana nomqhaphu, ihempe, uboya kunye nesilika inokusetyenziselwa ukuvelisa amalaphu angalukwanga.Abanye abantu bahlala becinga ngamalaphu angalukwanga njengeemveliso zemichiza yefiber xa bekhankanya amalaphu angalukwanga, nto leyo eneneni kukungaqondi kakuhle amalaphu angalukwanga.Njengamalaphu esiqhele ukuwanxiba, amalaphu angalukwanga nawo ahlulahlulwe abe ngamalaphu osinga lwemichiza angalukwanga kunye namalaphu endalo angalukwanga efayibha, kodwa amalaphu ekhemikhali angalukwanga axhaphake kakhulu.Ndingathanda ukukhumbuza wonke umntu apha ukuba ayizizo zonke iimveliso ezibizwa ngokuba yi "cotton towels" ezenziwe nge "cotton" fibers.Kukho iitawuli zomqhaphu emarikeni ezenziwe ngokwenene ngeentsinga zekhemikhali, kodwa ziziva ngathi ngumqhaphu ngakumbi., kufuneka uqaphele izithako xa uthenga)
