1.Spandex fiber
I-Spandex fiber (ebizwa ngokuba yi-PU fiber) yeyolwakhiwo lwe-polyurethane enobude obuphezulu, imodyuli ephantsi ye-elastic kunye nezinga eliphezulu lokubuyisela. Ukongeza, i-spandex nayo inozinzo oluhle kakhulu lweekhemikhali kunye nokuzinza kwe-thermal. Iyakwazi ukumelana neekhemikhali kunesilika yelatex. Ukuthotywa, ubushushu obuthambileyo bungaphezulu kwama-200 ℃. Iintsinga zeSpandex zixhathisa ukubila, amanzi olwandle kunye nezicoci ezomileyo ezohlukeneyo kunye nezikhuselo zelanga ezininzi. Ukubonakaliswa kwexesha elide kukukhanya kwelanga okanye i-chlorine bleach nako kunokuphela, kodwa iqondo lokubuna liyahluka ngokubanzi ngokuxhomekeke kuhlobo lwe-spandex. Impahla eyenziwe ngelaphu eline-spandex inokugcinwa kakuhle kwemilo, ubungakanani obuzinzile, akukho xinzelelo kunye nokunxiba kakuhle. Ngokuqhelekileyo, kuphela i-2% ukuya kwi-10% ye-spandex inokongezwa ukwenza iingubo zangaphantsi zithambile kwaye zisondele kumzimba, zikhululekile kwaye zihle, zenze iimpahla zemidlalo zifane kwaye zihambe ngokukhululekileyo, kwaye zenze imfashini kunye neempahla eziqhelekileyo zibe ne-drape efanelekileyo, ukugcinwa kwemilo kunye nefashoni. Ke ngoko, i-spandex yifayibha eyimfuneko ekuphuhliseni amalaphu anwebekayo kakhulu.
2.Polytrimethylene terephthalate fiber
I-Polytrimethylene terephthalate fiber (i-PTT fiber ngokufutshane) yimveliso entsha kwintsapho ye-polyester. Yeyokwe-polyester fiber kwaye iyimveliso eqhelekileyo ye-polyester PET. Ifayibha ye-PTT ineempawu zombini zepolyester kunye nenayiloni, isandla esithambileyo, ukubuyiswa kakuhle kwe-elastic, kulula ukudaya phantsi koxinzelelo oluqhelekileyo, umbala oqaqambileyo, uzinzo olufanelekileyo lwelaphu, lufaneleke kakhulu kwintsimi yempahla. Ifayibha ye-PTT inokudityaniswa, ijijelwe kwaye idityaniswe neentsinga zendalo okanye iintsinga zokwenziwa ezifana noboya kunye nomqhaphu, kwaye zingasetyenziswa kumalaphu alukiweyo kunye namalaphu anithiweyo. Ukongeza, iifiber ze-PTT zisenokusetyenziswa kumalaphu emizi-mveliso nakwamanye amasimi, njengokwenziwa kweekhaphethi, imihombiso, i-webbing njalo njalo. Ifayibha ye-PTT inoncedo lwelaphu elastiki le-spandex, kwaye ixabiso lisezantsi kunelaphu elastiki le-spandex. Lusinga olutsha oluthembisayo.
I-3.T-400 ifayibha
I-T-400 ifayibha luhlobo olutsha lwemveliso ye-elastic fiber ephuhliswe yi-DuPont yokunciphisa i-spandex fiber kwi-textile applications. I-T-400 ayiyiyo intsapho ye-spandex. Ijijelwe ecaleni kweepolymer ezimbini, iPTT kunye nePET, ezinamaqondo ahlukeneyo okushwabana. Yifiber edibeneyo esecaleni. Isombulula iingxaki ezininzi ze-spandex ezinjengokudaya nzima, ukuqina okugqithisileyo, ukuluka okuntsonkothileyo, ubungakanani belaphu obungazinzanga kunye nokuguga kwe-spandex ngexesha lokusetyenziswa.
Amalaphu enziwe ngayo anezi mpawu zilandelayo:
(1) I-elasticity ilula, ikhululekile kwaye ihlala ixesha elide; (2) Ilaphu lithambile, liqinile kwaye linemizobo entle; (3) Umphezulu welaphu usicaba kwaye unokumelana nokushwabana okuhle; (4) Ukufunxa ukufuma kunye nokoma ngokukhawuleza, imvakalelo egudileyo yesandla; (5) Uzinzo olulungileyo lwe-dimensional kwaye kulula ukuphatha.
I-T-400 inokudityaniswa neentsinga zendalo kunye neentsinga ezenziwe ngabantu ukuphucula amandla kunye nokuthamba, ukubonakala kwamalaphu adityanisiweyo kucocekile kwaye agudileyo, ulwandlalo lwempahla lucacile, iimpahla zisenokugcina imilo entle emva kokuhlanjwa ngokuphindaphindiweyo. ilaphu linombala omhle wokukhawuleza, akukho lula ukubuna, ixesha elide Inxibe njengentsha. Okwangoku, i-T-400 isetyenziswa ngokubanzi kwiibhulukhwe, i-denim, iimpahla zezemidlalo, iimpahla zabasetyhini eziphezulu kunye nezinye iindawo ngenxa yokusebenza kwayo kakuhle.
Indlela yokutshisa kukuchonga uhlobo lwefayibha ngokusebenzisa umahluko kwimichiza yokwakheka kwemicu eyahlukeneyo kunye nokwahluka kweempawu zokutsha eziveliswayo. Indlela yokuthatha iisampulu ezincinci zeesampulu zefiber kwaye uzitshise emlilweni, uqwalasele ngokucophelela iimpawu ezivuthayo zemicu kunye nokumila, umbala, ukuthamba kunye nobunzima beentsalela, kwaye kwangaxeshanye ukuvumba ivumba eliveliswa ngabo.
Iimpawu ezivuthayo zemicu emithathu elastiki
