Itandukaniro Hagati ya Polyester Yarn na Nylon Yarn

Hano hari isoko ryinshi ryo kudoda.Muri byo, polyester idoda thead na nyon fiaments ni twro ubwoko busanzwe bwo kudoda ikipi Uzi itandukaniro riri hagati yabo?Ubutaha tuzakumenyesha itandukaniro riri hagati yintambara ya polyester na nylon.

Ibyerekeye polyester

Polyester ni ubwoko bwingenzi muri fibre synthique kandi nizina ryubucuruzi bwa fibre polyester mubushinwa.Polimeri ikora fibre yakozwe na esterification cyangwa transesterification hamwe na polycondensation ya PTA cyangwa DMT naMEG-Polyethylene terephthalate (PET).Ni fibre ikozwe no kuzunguruka no nyuma yo kuvurwa.

Ibyerekeye nylon

Nylon yatejwe imbere na Carothers, umuhanga w’umunyamerika, nitsinda ry’ubushakashatsi iyobowe na we.Nibintu byambere bya fibre synthique kwisi.Nylon ni ubwoko bwa fibre polyamide.Kugaragara kwa nylon byahinduye ibicuruzwa byimyenda.Synthesis yayo ni intambwe ikomeye mu nganda ya fibre synthique kandi ni intambwe ikomeye cyane muri chimie ya polymer.

Itandukaniro mubikorwa

Imikorere ya Nylon

Mukomere, wihanganira kwambara, urutonde rwa mbere muri fibre zose.Kurwanya kwangirika kwayo ni inshuro 10 zi fibre na fibre yumye ya viscose, ninshuro 140 zibyo bya fibre itose.Kubwibyo, kuramba kwayo ni byiza.Kugarura ibintu byoroshye kandi byoroshye byanylon nibyiza cyane, ariko byoroshye guhindurwa nimbaraga zo hanze, bityo umwenda ukabyimba byoroshye mugihe cyo kwambara.Birakennye muguhumeka kandi byoroshye kubyara amashanyarazi ahamye.

Imikorere ya Polyester

Imbaraga nyinshi

Imbaraga za fibre ngufi ni 2,6 kugeza 5.7 cN / dtex, naho fibre ikomeye ni 5.6 kugeza 8.0 cN / dtex.Bitewe na hygroscopique nkeya, imbaraga zayo zitose ni nkimbaraga zumye.Imbaraga zingaruka ziruta inshuro 4 kurenza nylon ninshuro 20 kurenza viscose.

Elastique nziza

Elastique yegereye iy'ubwoya, iyo irambuwe na 5% kugeza kuri 6%, irashobora gukira hafi.Kurwanya inkeke biruta izindi fibre, ni ukuvuga, umwenda ntabwo wijimye, kandi guhagarara neza ni byiza.Modulus ya elastique ni 22 kugeza 141 cN / dtex, iruta inshuro 2 kugeza kuri 3 kurenza iya nylon.

Amazi meza

Kurwanya gusya neza.Kwambara birwanya polyester ni icya kabiri nyuma ya nylon.Nibyiza kuruta izindi fibre naturel na sintetike, kandi irwanya urumuri rwa kabiri nyuma ya fibre acrylic.

Itandukaniro hagati yo gukoresha polyester na nylon

Urebye hygroscopicity, nyion fabricis ubwoko bwiza mumyenda yubukorikori, bityo imikino ikozwe na nylon iroroshye kwambara kuruta imikino ya polyester.lt ifite ibibyimba byiza hamwe no kurwanya ruswa, ariko ubushyuhe na lghtresistance ntabwo ari byiza bihagije. Ubushyuhe bwo gutondeka bugomba gukonjeshwa munsi ya 140 ℃ C. Witondere konditoni yo gukaraba no kuyitaho, kugirango utangiza imyenda.Imyenda ya Nylon ni fabic yoroheje, ikaba ited gusa afe polypropilene nigitambara cya acrylic mumyenda yubukorikori.Kubwibyo, birakwiriye kumyenda yimisozi nigitambara cyimbeho.

Imyenda ya polyester ifite hygroscopicite mbi kandi iroroshye iyo yambaye.Biroroshye gutwara amashanyarazi ahamye hamwe n ivumbi ryanduye, bigira ingaruka kumiterere no guhumurizwa.Ariko, biroroshye cyane gukama nyuma yo gukaraba, kandi ntabwo byahinduwe.Polyester nigitambara cyiza kirwanya ubushyuhe mumyenda yubukorikori.Ahantu ho gushonga ni 260 ° C kandi ubushyuhe bwicyuma bushobora kuba 180 ° C. Ifite parfomance ya termoplastique kandi irashobora gukorwa mumajipo ishimishije hamwe no kwinginga birebire.

Imyenda ya polyester ifite imbaraga zo gushonga, kandi biroroshye gukora umwobo mugihe cya soot cyangwa mars.Kubwibyo, kwambara umwenda wa polyester bigomba kwirinda guhura nigituba cyitabi, ibishashi, nibindi.
