Dacron ni ubwoko butandukanye bwa fibre synthique kandi ni izina ryubucuruzi bwa fibre polyester mubushinwa.Ishingiye kuri acide terephthalic (PTA) cyangwa acide dimethyl terephthalic (DMT) na Ethylene glycol (MEG) nkibikoresho fatizo, binyuze muri esterification cyangwa transesterification na polycondensation reaction no gutegura polymer - polyethylene terephthalate (PET), kuzunguruka na nyuma- gutunganya bikozwe muri fibre.Ibyo bita polyester filament nuburebure bwa kilometero zirenga zidoda, igikomere cyakomerekejwe mumupira.Ukurikije uburyo butandukanye bwo gukora, filime ya polyester isanzwe igabanyijemo ibyiciro bitatu: filime yibanze, kurambura filament na deformation filament.
Ibiranga polyester filament
Imbaraga: Fibre ya polyester ikubye hafi kabiri ipamba ninshuro eshatu nkubwoya, ubwo rero imyenda ya polyester irakomeye kandi iramba.
Kurwanya ubushyuhe: birashobora gukoreshwa muri -70 ℃ ~ 170 ℃, nuburyo bwiza bwo kurwanya ubushyuhe hamwe nubushyuhe bwumuriro wa fibre synthique.
Elastique: Elastique ya polyester yegereye ubwoya, kandi kurwanya crease nibyiza kuruta izindi fibre.Umwenda utagira inkeke kandi ufite imiterere myiza.
Kwambara kwambara: Polyester kwambara birwanya kabiri nyuma ya nylon, kumwanya wa kabiri muri fibre synthique.
Kwinjiza amazi: Polyester ifite amazi make yo kwifata hamwe nigipimo cyo kugarura amazi nubushakashatsi bwiza.Nyamara, kubera kwinjiza amazi make hamwe n’amashanyarazi menshi ahamye biterwa no guterana amagambo, imikorere ya adsorption isanzwe y irangi ni mibi.Kubwibyo, polyester isanzwe irangi nubushyuhe bwo hejuru hamwe no gusiga irangi ryinshi.
Irangi: Polyester ubwayo ibura amatsinda ya hydrophilique cyangwa ibice byakira amarangi, bityo irangi rya polyester rikennye, rishobora gusiga irangi ryirangi cyangwa irangi ritari ionic, ariko ibintu byo gusiga birakomeye.
Gukoresha polyester filament
Polyester nka fibre yimyenda, umwenda wacyo nyuma yo gukaraba kugirango ugere ku ngaruka zidafite inkari, zitari icyuma.Polyester ikunze kuvangwa cyangwa kuvangwa na fibre zitandukanye, nka pamba polyester, polyester yubwoya, nibindi, bikoreshwa cyane mubikoresho bitandukanye byimyenda nibikoresho byo gushushanya.Polyester irashobora gukoreshwa muruganda umukandara wa convoyeur, ihema, canvas, umugozi, inshundura zuburobyi, nibindi, cyane cyane kumurongo wa tine polyester, wegereye nylon mubikorwa.Polyester irashobora kandi gukoreshwa mubikoresho byo gukwirakwiza amashanyarazi, imyenda irwanya aside, imyenda ya farumasi yinganda, nibindi. kurwanya ubushyuhe, uburemere bworoshye, ubushyuhe, kubika amashanyarazi neza no kurwanya indwara.
