1.I-Polyesterifayibha
I-polyester fiber iyi-polyester, ingeyohlobo lwe-polyester oluguquliwe, ingeyohlobo oluphathwayo (oluguquliwe ngabangani bayakhumbula) ithuthukisa okuqukethwe kwamanzi e-polyester kuphansi, ukungena kahle kwamanzi, ukudaya kabi, ukuphotha okulula, ukudaya kalula kanye nokunye ukushiyeka. Isekelwe ku-terephthalic acid ecwengisisiwe (PTA) noma i-dimethyl terephthalate (DMT) kanye ne-ethylene glycol (EG) njengezinto zokusetshenziswa ngokusebenzisa i-esterification noma i-transesterification kanye ne-condensation reaction ukulungiselela i-polymer eyakhayo - i-polyethylene terephthalate (PET), ephothiwe kanye ne-post-treatment eyenziwe nge-fiber.
Izinzuzo: ukukhanya okukhanyayo, okunomphumela we-flash, kuzwakala kubushelelezi, kuyisicaba, kuyanwebeka kahle; Uku-ayina okuvimbela imibimbi, ukumelana nokukhanya okuhle; Bamba isilika ngokuqinile ngesandla bese uyikhulula ngaphandle kokugoba okusobala.
Okubi: ukukhazimula akuthambile ngokwanele, ukumunca kahle kwamanzi, ukudaya okunzima, ukumelana nokuncibilika okubi, kulula ukwakha izimbobo ebusweni bomsi, iMars njalo njalo.
Ukutholakala kwe-polyester
I-Polyester, eyasungulwa ngo-1942 ngu-JR Whitfield no-JT Dixon, yaphefumulelwa ucwaningo luka-WH Carothers, usosayensi waseMelika owathola i-nylon! Uma isetshenziswa njenge-fiber, ibizwa nangokuthi i-polyester, futhi uma isetshenziswa, isibonelo, emabhodleleni eziphuzo zepulasitiki, ibizwa ngokuthi i-PET.
Inqubo: Ukukhiqizwa kwemicu ye-polyester kuvame ukuhilela izinyathelo ezilandelayo
(1) Ukwenziwa kwe-polymer: i-terephthalic acid kanye ne-ethylene glycol (ngokuvamile i-ethylene glycol) kwenziwa i-polymer ukuze kwakheke i-polyester polymer;
(2) Ukuphotha: ngokuncibilikisa i-polymer bese udlula epuletini lembobo elijikelezayo ukuze kwakheke i-fiber eqhubekayo;
(3) Ukwelapha nokwelula: imicu iyapholiswa futhi ipholiswe futhi inwetshwe esihlahleni ukuze kuthuthukiswe amandla nokuqina;
(4) Ukwakheka kanye nokwelashwa ngemva kokwelashwa: imicu ingakhiwa ngezindlela ezahlukene ezifana nendwangu, ukuluka, ukuthunga, kanye nokwelashwa ngemva kokwelashwa, njengokudaya, ukuphrinta kanye nokuqeda
I-polyester iyona elula kunazo zonke izinhlobo ezintathu zemicu yokwenziwa, futhi intengo yayo ishibhile. Iwuhlobo lwendwangu yezingubo zemicu yamakhemikhali esetshenziswa ekuphileni kwansuku zonke. Inzuzo yayo enkulu ukuthi inokumelana okuhle nokushwabana kanye nokugcinwa komumo, ngakho-ke ifaneleka ezintweni zangaphandle njengezingubo zangaphandle, zonke izinhlobo zezikhwama namatende.
Izinzuzo: amandla aphezulu, ukuqina okuqinile okufana noboya; Ukumelana nokushisa, ukumelana nokukhanya, ukumelana nokuguguleka okuhle kanye nokumelana okuhle kwamakhemikhali;
Okubi: ukudaya okungekuhle, ukumelana nokuncibilika okubi, ukumuncwa okungekuhle komswakama kanye nokulula ukuwufaka, kulula ukuwudaya.
2.Ukotini
Kubhekisela endwangu ekhiqizwe ngokotini njengezinto zokusetshenziswa. Ngokuvamile, izindwangu zikakotini zinokumuncwa okungcono komswakama kanye nokumelana nokushisa futhi zikhululekile ukuzigqoka. Eminye imboni yezingubo enezidingo eziphezulu zokumuncwa komswakama ingakhetha izindwangu zikakotini ezihlanzekile ukuze zicutshungulwe. Isibonelo, iyunifomu yesikole ehlobo.
Izinzuzo: ukumuncwa komswakama wefayibha kakotini kungcono, ukunwebeka nakho kuphakeme kakhulu, ukumelana nokushisa kanye ne-alkali, impilo;
Okubi: kulula ukushwabana, kulula ukushwabana, kulula ukuguquguquka, kulula ukunamathela izinwele kuyesaba kakhulu i-asidi, uma ukotini ohlanganisiwe we-sulfuric acid unombala, ukotini ushiswa ube yimigodi.
3.Inayiloni
I-nylon yigama lesiShayina le-synthetic fiber nylon, igama lokuhumusha libizwa nangokuthi "nylon", "nylon", igama lesayensi yi-polyamide fiber, okungukuthi, i-polyamide fiber. Ngenxa yokuthi i-Jinzhou chemical fiber factory iyifektri yokuqala ye-synthetic polyamide fibre ezweni lethu, ibizwa ngokuthi "nylon". Iwuhlobo lwe-synthetic fiber lokuqala emhlabeni, ngenxa yokusebenza kwayo okuhle kakhulu, izinsizakusebenza ezicebile zezinto zokusetshenziswa, isetshenziswe kabanzi.
Izinzuzo: ukumelana nokuguguleka okuqinile, okuhamba phambili phakathi kwazo zonke izinhlobo zemicu; Ukuqina nokuqina kwendwangu ye-nylon kuhle kakhulu.
Okubi: Kulula ukuguguleka ngaphansi kwamandla amancane angaphandle, ngakho-ke indwangu yayo kulula ukuyiguguleka ngesikhathi iguguleka; Umoya omncane, kulula ukukhiqiza ugesi ongaguquki.
4.I-Spandex
I-Spandex uhlobo lwe-polyurethane fiber, ngenxa yokuqina kwayo okuhle kakhulu, yaziwa nangokuthi i-elastic fiber, ebilokhu isetshenziswa kakhulu ezindwangu zezingubo futhi inezici zokuqina okuphezulu. Isetshenziswa kakhulu ekwenziweni kwezingubo eziqinile, izembatho zezemidlalo, i-jockstrap kanye ne-sole, njll. Ububanzi bayo ngokwezidingo zokusetshenziswa, bungahlukaniswa ngendwangu ye-warp elastic, indwangu ye-weft elastic kanye nendwangu ye-warp kanye ne-weft enezindlela ezimbili.
Izinzuzo: ukwandiswa okukhulu, ukugcinwa okuhle kwesimo, kanye nokungabi nemibimbi; Ukuqina okungcono kakhulu, ukumelana nokukhanya okuhle, ukumelana ne-asidi, ukumelana ne-alkali, ukumelana nokuguguleka; Inempahla enhle yokudaya futhi akufanele iphele.
Okubi: amandla amabi kakhulu, ukumuncwa kabi komswakama; I-Spandex ngokuvamile ayisetshenziswa yodwa, kodwa ixutshwa nezinye izindwangu; Ukumelana nokushisa okubi.
