1.Polyesterfaibha
Polyester fiber ipolyester, ndeye polyester yakagadziriswa, ndeyemhando yakarapwa (yakagadziriswa neshamwari yeuka) inovandudza huwandu hwemvura yepolyester hwakaderera, husina kupinza zvakanaka, husina kudhaya zvakanaka, husina kupfava, husina kutsvukira uye zvimwe zvikanganiso. Yakavakirwa pane yakagadziriswa terephthalic acid (PTA) kana dimethyl terephthalate (DMT) uye ethylene glycol (EG) sezvinhu zvakagadzirwa kuburikidza ne esterification kana transesterification uye condensation reaction kugadzirira polymer inogadzira - polyethylene terephthalate (PET), yakagadzirwa ne fiber yakarukwa uye yakaitwa ne fiber mushure mekurapwa.
Zvakanakira: kupenya kwakajeka, ine simba rekupenya, inonzwa yakatsetseka, yakati sandara, inochinjika zvakanaka; Inorwisa kuayina makwinya, inodzivirira chiedza zvakanaka; Bata siriki zvakasimba neruoko wosunungura pasina kukwenya kuoneka.
Zvakashata: kupenya hakuna kunyorova zvakakwana, kupenya kwakashata, kuoma kudhaya, kusanyunguduka kwakashata, nyore kugadzira maburi pamberi pesoot, Mars nezvimwewo.
Kuwanikwa kwepolyester
Polyester, yakagadzirwa muna 1942 naJR Whitfield naJT Dixon, yakafuridzirwa nekutsvagurudza kwaWH Carothers, musayendisiti wekuAmerica akawana nayiloni! Kana ikashandiswa sefaibha, inonziwo polyester, uye kana ikashandiswa, semuenzaniso, mumabhodhoro ezvinwiwa zvepurasitiki, inonzi PET.
Maitiro: Kugadzirwa kwefibers dzepolyester kunowanzo sanganisira matanho anotevera
(1) Kuumbwa kwepolymer: terephthalic acid ne ethylene glycol (kazhinji ethylene glycol) zvinoumbwa kuti zvigadzire polyester polymer;
(2) Kutenderera: nekunyungudutsa polymer wopfuura nepakati pepuranga rinotenderera kuti pave nefiber inoenderera mberi;
(3) Kuchenesa nekutambanudza: shinda dzinotonhodzwa uye dzogadziriswa uye dzotambanudzwa pamubhedha kuti dziwedzere kusimba uye kugara kwenguva refu;
(4) Kugadzira uye mushure mekugadzirisa: fibers dzinogona kugadzirwa nenzira dzakasiyana-siyana dzakadai semachira, kuruka, kusona, uye mushure mekugadzirisa, zvakaita sekudhaya, kudhinda uye kupedzisa
Polyester ndiyo iri nyore pane matatu machira ekugadzira, uye mutengo wayo wakachipa. Imhando yejira remachira emakemikari anoshandiswa muhupenyu hwezuva nezuva. Chinhu chikuru chakanakira ndechekuti ine simba rakanaka rekudzivirira makwinya uye inogara kwenguva refu, saka yakakodzera zvinhu zvekunze zvakaita sehembe dzekunze, mabhegi emhando dzese nematende.
Zvakanakira: simba rakawanda, kupfava kwakasimba kwakafanana nemvere dzemakwai; Kudzivirira kupisa, kushivirira chiedza, kushivirira kupfeka zvakanaka uye kushivirira makemikari zvakanaka;
Zvakashata: kusava nemavara akanaka, kusanyunguduka zvakanaka, kusapinza hunyoro zvakanaka uye kusabvisa hunyoro nyore, kusasvibisa nyore.
2.Donje
Zvinoreva jira rinogadzirwa nedonje sezvinhu zvisina kugadzirwa. Kazhinji, machira edonje anopinza hunyoro zviri nani uye haapise kupisa uye akasununguka kupfeka. Mamwe maindasitiri ezvipfeko ane zvinodiwa zvakanyanya zvekupinza hunyoro anogona kusarudza machira edonje chaiwo ekugadzirisa. Semuenzaniso, yunifomu yechikoro muzhizha.
Zvakanakira: kunyudzwa kwehunyoro hwekotoni nefiber kuri nani, kusimba kwemuchina kwakakwirawo, kupisa uye alkali zvinoramba zviripo, hutano;
Zvakashata: nyore kumonana, nyore kupfupika, nyore kuchinja, nyore kunamira bvudzi rinotya acid zvakanyanya, kana donje rakasanganiswa nesulfuric acid, donje rinopiswa kuita maburi.
3.Naironi
Nayiloni izita rechiChinese renayiloni yefaibha yakagadzirwa, zita rekushandura rinonziwo "nylon", "nylon", zita resainzi ifaibha yepolyamide, kureva kuti, faibha yepolyamide. Nekuti Jinzhou chemical fiber factory ndiyo fekitori yekutanga yefaibha yepolyamide yakagadzirwa munyika medu, inonzi "nylon". Ndiyo mhando yekutanga yepasi rose yefaibha yekugadzira, nekuda kwekushanda kwayo kwakanaka, zviwanikwa zvakawanda zvemidziyo, yakashandiswa zvakanyanya.
Zvakanakira: yakasimba, inodzivirira kupfeka zvakanaka, iri pamberi pemafiber ese; Kusimba uye kusimba kwejira renylon zvakanaka kwazvo.
Zvakashata: Zviri nyore kukanganisika kana simba rekunze diki, saka jira rayo rinoita nyore kukanganisika kana richipfekwa; Kufefetera kusina kunaka, zviri nyore kugadzira magetsi asingachinji.
4.Spandex
Spandex imhando yefiber yepolyurethane, nekuda kwekusimba kwayo kwakanyanya, inozivikanwawo sefiber ye elastic, iyo yave ichishandiswa zvakanyanya mumachira ezvipfeko uye ine hunhu hwekusimba kwakanyanya. Inonyanya kushandiswa mukugadzira zvipfeko zvakasimba, zvipfeko zvemitambo, jockstrap uye sole, nezvimwewo. Mhando dzayo dzinoenderana nezvinodiwa pakushandiswa, dzinogona kukamurwa kuita jira re warp elastic, jira re weft elastic uye jira re warp and weft re two-way elastic.
Zvakanakira: yakakura, inochengetedza chimiro chayo zvakanaka, uye haina makwinya; Inochinjika zvakanyanya, inodzivirira chiedza zvakanaka, inodzivirira acid, inodzivirira alkali, inodzivirira kupera; Ine hunhu hwakanaka hwekudhaya uye haifanirwe kupera simba.
Zvakashata: kusimba kwakanyanya, kusapinza hunyoro zvakanaka; Spandex haiwanzo shandiswa yoga, asi inosanganiswa nemamwe machira; Kusakwanisa kupisa zvakanaka.
