Kune shinda dzakawanda dzekusona pamusika.Pakati pazvo, polyester yekusonesa tedhi uye nyon fiaments mhando mbiri dzakajairika dzekusona Unoziva mutsauko uripo here?Tevere tichakuzivisa iwe musiyano pakati pepolyester yarn nenaironi.
Nezve polyester
Polyester yakakosha siyana musynthetic fiber uye izita rekutengesa repolyester fiber kuChina.Fiber-forming polymer inogadzirwa ne esterification kana transesterification uye polycondensation yePTA kana DMT uyeMEG-Polyethylene terephthalate (PET).Iyo fiber yakagadzirwa nekutenderera uye mushure mekurapa.
Nezve naironi
Nylon yakagadzirwa naCarothers, musayendisiti weAmerica, uye boka rekutsvakurudza rinotungamirirwa naye.Ndiyo yekutanga fiber fiber munyika.Nylon imhando ye polyamide fiber.Kutaridzika kwenylon kwakashandura zvigadzirwa zvemachira.Kubatanidzwa kwayo ndiko kubudirira kukuru muindasitiri yekugadzira fiber uye idanho rakakosha kwazvo mumakemikari epolymer.
Kusiyana Kwekuita
Naironi kuita
Yakasimba, isingapfeki, inomira pekutanga pakati pemafayibha ese.Kupfeka-kupokana kwayo ndeye 10 nguva dzeiyo yekotoni fiber uye yakaoma viscose fiber, uye 140 nguva yeiyo yemvura fiber.Nokudaro, kusimba kwayo kwakanakisisa.Iyo elastic uye elastic kupora kweiyojira renaironi ndiroyakanaka kwazvo, asi inokanganiswa nyore nyore nechisimba chekunze, saka jira rinokwinya nyore panguva yekupfeka.Haina kufefetera zvakanaka uye iri nyore kugadzira magetsi akamira.
Polyester Performance
Simba repamusoro
Iyo pfupi fiber simba ndeye 2.6 kusvika 5.7 cN/dtex, uye iyo yakakwirira simba fiber i5.6 kusvika 8.0 cN/dtex.Nekuda kweiyo yakaderera hygroscopicity, kunyorova kwayo kwakangofanana nekuoma kwesimba.Simba rekuita rakakwirira 4 nguva kupfuura yenylon uye 20 nguva yakakwirira kudarika viscose.
Zvakanaka elasticity
Iyo elasticity iri pedyo neiyo yemvere dzemakwai, kana yakatambanudzwa ne5% kusvika 6%, inogona kunge yakanyatso kudzoreredzwa.Iyo wrinkle yekudzivirira yakakwirira kune mamwe mafibhi, ndiko kuti, jira harina kuunyana, uye iyo dimensional kugadzikana kwakanaka.Iyo modulus ye elasticity ndeye 22 kusvika 141 cN/dtex, iyo inokwira kaviri kusvika katatu kupfuura iyo naironi.
Kunwa kwakanaka kwemvura
Kuramba kwakanaka kwekukuya.Pfeka kuramba kwepolyester yechipiri chete kune nylon.Iri nani pane mamwe masikirwo uye ekugadzira fibers, uye chiedza chayo chekudzivirira ndeyechipiri kune acrylic fiber.
Kusiyana pakati pekushandiswa kwepolyester nenylon
Tichifunga nezve hygroscopicity, nyion machira akanaka akasiyana mumachira ekugadzira, saka magemhu akagadzirwa naironi anonyanya kupfekwa kupfuura machira epolyester.Iine sputum yakanaka uye inodzivirira corosion, asi kupisa uye lghtresistance hazvina kunaka zvakakwana. Tembiricha ye roning inofanira kuderedzwa pazasi 140 ℃ C. Teerera kune maconditons ekugezesa uye kugadzirisa, kuti usakuvadza jira. Nylon jira iri jira rakareruka, rinongoitwa afe polypropylene uye machira e acrylic mumachira ekugadzira.Nokudaro, zvakakodzera kukwira makomo jira uye jira rechando.
Mucheka wepolyester hauna hygroscopicity uye unopisa kana uchipfeka.Zviri nyore kutakura static magetsi uye tsvina yeguruva, iyo inokanganisa chitarisiko uye nyaradzo.Zvisinei, zviri nyore kwazvo kuomesa mushure mekugeza, uye hazvina kuremara.Polyester ndiyo yakanakisa jira rinodzivirira kupisa mumachira ekugadzira.Nzvimbo yakanyunguduka ndeye 260 ° C uye tembiricha ye ironing inogona kuva 180 ° C. Iine thermoplastic perfomance uye inogona kugadzirwa mumucheka wakapfava une pleats refu.
Iro jira repolyester harina kunyungudika kunyungudika, uye zviri nyore kugadzira maburi kana soot kana mars.Nokudaro, kupfeka jira repolyester kunofanira kudzivisa kusangana nemidzanga yefodya, sparks, etc. Micheka yepolyester ine kumira kwakanaka kwekukwinya uye kuchengetedza chimiro, saka inokodzera zvipfeko zvekunze.
