1.Polyesterfibre
Fibre ya polyester ni polyester, ni iya polyester yahinduwe, ni iya ubwoko bwavuwe (byahinduwe n'inshuti bibutsa) irushaho kuba nziza ku rugero rw'amazi ya polyester ari make, nta ruhushya rwo kwinjira, nta irangi ryiza, nta gusiga amavuta byoroshye, nta gusiga irangi byoroshye n'ibindi bidafite akamaro. Ishingiye kuri aside terephthalate (PTA) yatunganyijwe neza cyangwa dimethyl terephthalate (DMT) na ethylene glycol (EG) nk'ibikoresho fatizo binyuze mu gupima cyangwa guhindura imisemburo no gushonga kugira ngo hategurwe polymer - polyethylene terephthalate (PET), yakozwe mu buryo bwa fibre nyuma yo kuyitunganya.
Ibyiza: Kurabagirana cyane, bifite ingaruka nziza zo gukurura, kumva byoroshye, birambuye, bifite ubushobozi bwo gukaraba neza; Kurwanya iminkanyari, birwanya urumuri; Fata ubudodo neza n'intoki hanyuma ubohore nta minkanyari igaragara.
Ingaruka mbi: ubwiza ntibuhagije, ubwinshi bw'amazi ntibushobora kwinjira neza, irangi riragoye, ubwiyongere buke bwo gushonga, byoroshye gukora imyobo mu maso y'umuserebanya, Mars n'ibindi.
Ivumburwa rya polyester
Polyester, yavumbuwe mu 1942 na JR Whitfield na JT Dixon, yahumetswe n'ubushakashatsi bwa WH Carothers, umuhanga mu bya siyansi w'Umunyamerika wavumbuye nylon! Iyo ikoreshejwe nk'umunyu, yitwa kandi polyester, kandi iyo ikoreshejwe, urugero, mu macupa y'ibinyobwa bya pulasitiki, yitwa PET.
Uburyo: Gukora imigozi ya polyester bikunze kuba bikubiyemo intambwe zikurikira
(1) Guhinduranya: aside terephtalike na ethylene glycol (ubusanzwe ethylene glycol) bihindurwamo polymer kugira ngo bikore polymer ya polyester;
(2) Kuzunguruka: mu gushonga polymer no kunyura mu gice cy'umuyoboro uzunguruka kugira ngo habeho fibre ikomeza;
(3) Gutunganya no kunanura: insinga zirakonjeshwa kandi zigakira kandi zigakwirakwizwa ku gitambaro kugira ngo zongere imbaraga n'uburambe;
(4) Gukora no gutunganya: insinga zishobora gukorwa binyuze mu buryo butandukanye nko mu myenda, kuboha, kudoda, no gutunganya, nko gusiga irangi, gucapa no kurangiza
Polyester ni yo yoroshye cyane muri izo fibre eshatu zikoze mu nganda, kandi igiciro cyayo kirahendutse. Ni ubwoko bw'imyenda ikoze mu nganda ikoreshwa mu buzima bwa buri munsi. Akamaro kayo kanini ni uko irwanya iminkanyari kandi ikarinda imiterere yayo, bityo ikaba ikwiriye ibikoresho byo hanze nko kwambara imyenda yo hanze, ubwoko bwose bw'amasakoshi n'amahema.
Ibyiza: gukomera cyane, ubushyuhe bwinshi hafi y'ubwoya; Kurwanya ubushyuhe, kudashira, kudashira neza no kudashira neza;
Ibibi: irangi ribi, kudashonga neza, kudafata amazi neza no kuyasiga byoroshye, kandi byoroshye kuyasiga.
2.Ipamba
Bivuga ko umwenda ukorwa mu ipamba ari ibikoresho fatizo. Muri rusange, imyenda y'ipamba ifite ubushobozi bwo gufata ubushuhe no kwihanganira ubushyuhe kandi yoroshye kwambara. Zimwe mu nganda z'imyenda zifite ubushobozi bwo gufata ubushuhe bwinshi zishobora guhitamo imyenda y'ipamba itunganywa. Urugero, imyenda y'ishuri mu mpeshyi.
Ibyiza: Gufata ubushuhe bwa fibre y'ipamba ni byiza, ubushyuhe nabwo buri hejuru, ubushyuhe n'ubudahangarwa bwa alkali, ubuzima bwiza;
Ibibi: byoroshye gushwanyagurika, byoroshye kugabanuka, byoroshye guhindura isura, byoroshye gufata umusatsi bitinya cyane cyane aside, iyo aside sulfure yivanze yandujwe ipamba, ipamba itwikwa mu mwobo.
3.Nayiloni
Nayiloni ni izina ry'igishinwa rya nayiloni y'ubudodo bw'ubudodo bw'ubudodo, izina ry'ubuhinduzi ryitwa kandi "nayiloni", "nayiloni", izina rya siyansi ni fibre ya polyamide, ni ukuvuga fibre ya polyamide. Kubera ko uruganda rwa Jinzhou chemical fiber ari rwo ruganda rwa mbere rwa polyamide rukora ubudodo bw'ubu ...
Ibyiza: ikomeye, idapfa kwangirika neza, iza ku mwanya wa mbere mu nsinga zose; Uburebure n'ubudahangarwa bw'imyenda ya nylon ni byiza cyane.
Ingaruka mbi: Biroroshye kwangirika bitewe n'imbaraga nke zo hanze, bityo umwenda wabyo woroshye kwangirika mu gihe cyo kwambara; Ubuhumekero buke, byoroshye gutanga amashanyarazi adahindagurika.
4.Spandex
Spandex ni ubwoko bwa fibre ya polyurethane, kubera ko ifite ubushobozi bwo gukurura cyane, izwi kandi nka fibre ya elastic, yakoreshejwe cyane mu myenda y'imyenda kandi ifite imiterere yo gukurura cyane. Ikoreshwa cyane cyane mu gukora imyenda ikomeye, imyenda ya siporo, umugozi wo gupfuka n'iy'inyuma, n'ibindi. Ubwoko bwayo hakurikijwe ibyo ikoreshwa, bushobora kugabanywamo imyenda ya elastic ya warp, imyenda ya elastic ya weft n'imyenda ya elastic ya warp na weft ifite inzira ebyiri.
Ibyiza: Ifite ubunini, igumana imiterere myiza, kandi ntigira iminkanyari; Irakomera cyane, irahangana n'urumuri, irahangana n'aside, irahangana n'aside, irahangana n'ubusa; Ifite ubushobozi bwo gusiga irangi ryiza kandi ntigomba gushwanyagurika.
Ingaruka mbi: gukomera cyane, ubushobozi bwo kuyungurura amazi nabi; Spandex ntabwo ikoreshwa yonyine, ahubwo ivangwa n'indi myenda; Kudakomera mu bushyuhe.
