Intambo yokuthunga isetshenziselwa ukuthunga zonke izinhlobo zezicathulo, izikhwama, amathoyizi, izindwangu zokugqoka nezinye izinto ezisizayo, ezinemisebenzi emibili: ewusizo nokuhlobisa.Izinga lokuthunga alithinti kuphela umphumela wokuthunga kanye nezindleko zokucubungula, kodwa futhi lithinta izinga lokubukeka kwemikhiqizo.Abantu ababambe iqhaza embonini yezingubo kumele baqonde umqondo ojwayelekile wokwakheka komthungo, ukusonta, ukuxhumana phakathi kwe-twist namandla, ukuhlukaniswa kwe-stitch, izici kanye nokusetshenziswa okuyinhloko, ukukhethwa komthungo nokunye ukuqonda.Umkhiqizi we-Elastic band
Okulandelayo isingeniso esifushane:
Okokuqala, umqondo wokuthunga intambo (ikhadi) ubhekisela entanjeni elukwe kuphela ngokuhlanza isiphetho esisodwa.Ukukama kubhekisela entanjeni ehlanzwa kuzo zombili iziphetho zefayibha ngomshini wokukama.Ukungcola kususiwe futhi i-fiber iqonde kakhulu.Ukuhlanganisa kusho intambo lapho imicu emibili noma ngaphezulu enezakhiwo ezihlukene ihlanganiswa ndawonye.Intambo eyodwa ibhekisela entanjeni eyakhiwe ngokuqondile ohlakeni lokuphotha, oluzosakazeka uma lungasontiwe.Intambo enemicu ibhekisela emiculweni emibili noma ngaphezulu ephothiwe ndawonye, ebizwa ngokuthi intambo ngokufushane.Intambo yokuthunga isho igama elijwayelekile lentambo esetshenziselwa ukuthunga izingubo neminye imikhiqizo ethungwe.Ukuphotha kwesitayela esisha kuhlukile kokuphotha kweringi yendabuko, futhi ingxenye eyodwa iphumulile, njengokuphotha komoya kanye nokuphotha okungqubuzanayo.Izintambo zihlanganiswe ngaphandle kokusonteka.Isibalo sentambo sisetshenziselwa ukukhombisa ukucoleka kwentambo, ikakhulukazi isibalo sesiNgisi, isibalo semethrikhi, ukubala okukhethekile kanye ne-denier.
Okwesibili, mayelana nomqondo we-twist: ngemva kokusonta isakhiwo se-fiber yomugqa, ukufuduka okuhlobene kwe-angular kwenzeka phakathi kwezingxenye eziphambanayo zomugqa, futhi i-fiber eqondile ihambisana ne-axis ukuze iguqule isakhiwo somugqa.Ukusonteka kungenza intambo ibe nemisebenzi ethile engokwenyama nemishini, njengamandla, ukunwebeka, ukwelula, ukucwebezela, ukuzwa kwesandla, njll. Kuboniswa ngenani lokusonteka ngobude beyunithi ngayinye, ngokuvamile inani lokuphenduka iyintshi ngayinye (TPI) noma inani lokujika imitha ngalinye (TPM).Ukusonta: Amadigri angu-360 azungeze i-eksisi iyi-twist.Isiqondiso sokusonta (i-S-direction noma i-Z-direction): isiqondiso esithambekile sokuzungeza esakhiwe ngokuzungezisa i-eksisi lapho umucu uqondile.Isiqondiso se-oblique se-twist direction ka-S sihlangene naphakathi kohlamvu S, okungukuthi, isiqondiso sesandla sokudla noma isiqondiso sewashi.Isiqondiso esitshekile se-Z twist sihlangene nendawo emaphakathi yohlamvu Z, okungukuthi, isiqondiso esingakwesokunxele noma isiqondiso esiphambene newashi.Ukuxhumana phakathi kwe-twist namandla: i-twist yentambo ilingana ngokuqondile namandla, kodwa ngemva kokusonta okuthile, amandla ayancipha.Uma i-twist inkulu kakhulu, i-twist angle izokwanda, futhi ukukhanya nokuzwakala kwentambo kuyoba mpofu;Ukusonteka okuncane kakhulu, izinwele kanye nokuzwakala kwesandla okuxekethile.Lokhu kungenxa yokuthi i-twist iyanda, ukumelana nokungqubuzana phakathi kwezintambo kuyanda, futhi amandla entambo ayanda.Kodwa-ke, ngokunyuka kwe-twist, ingxenye ye-axial yentambo iba mncane, futhi ukusatshalaliswa kokucindezeleka kwe-fiber ngaphakathi nangaphandle akulingani, okuholela ekushintshaneni kwe-fiber cracking.Ngamafuphi, umsebenzi wokuqhekeka namandla entambo kuhlobene eduze nokusonta, futhi ukusonteka nokusonteka kuncike ezidingweni zomkhiqizo kanye nokucubungula kwangemuva, ngokuvamile isiqondiso sokusonta esingu-Z.
