Cov ntaub polyester fiber yog dab tsi? Nws cov yam ntxwv yog dab tsi?

    Polyester Fiber Cov ntaub yog cov fiber hluavtaws tau los ntawm kev sib hloov polyester, uas tau condensed los ntawm cov organic dicarboxylic acids thiab diols. Daim ntawv tshawb fawb txog polyester saw hlau qhia tias cov polyester fibers tsim tawm ntau los ntawm kev lag luam yog ua los ntawm polyethylene terephthalate, uas yog muag hauv Suav teb raws li polyester. Tam sim no nws yog ntau yam khoom siv hluavtaws loj tshaj plaws.
Qhov hnyav tshwj xeeb ntawm polyester yog 1.38; Melting point ntawm 255-260 ℃, kev sib txuas pib ntawm 205 ℃, qhov kub thiab txias ironing zoo yog 135 ℃; Kev nqus dej noo tsawg heev, tsuas yog 0.4%; Lub zog tawg ntawm cov fibers ntev yog 4.5-5.5 grams ib denier, thaum cov fibers luv yog 3.5-5.5 grams ib denier; Qhov ntev ntawm kev tawg ntawm cov fibers ntev yog 15-25%, thaum cov fibers luv yog 25-40%; Cov fibers muaj zog siab tuaj yeem muaj lub zog ntawm 7-8 grams ib denier thiab kev ntev ntawm 7.5-12.5%. Polyester muaj kev tiv thaiv wrinkle zoo heev, elasticity, thiab kev ruaj khov ntawm qhov ntev, nrog rau cov khoom siv hluav taws xob zoo. Nws tiv taus lub hnub ci, kev sib txhuam, pwm thiab lwj, thiab muaj kev tiv thaiv zoo rau cov tshuaj reagents. Nws kuj tuaj yeem tiv taus cov kua qaub tsis muaj zog thiab cov hauv paus. Ntawm chav tsev kub, nws muaj qee qhov peev xwm tiv taus cov kua qaub muaj zog dilute, tab sis tsis zoo tiv taus cov alkalis muaj zog. Polyester muaj kev ua haujlwm dyeing tsis zoo thiab feem ntau yuav tsum tau dyed nrog dispersed dyes nyob rau hauv kub siab lossis nyob rau hauv lub xub ntiag ntawm lub carrier.

    Cov xov polyestermuaj lub zog siab thiab muaj peev xwm rov qab tau elastic, ua rau lawv ruaj khov, ruaj khov, Tiv taus kev ntsws, thiab tsis muaj hlau. Nws lub teeb tsis kam zoo, tsuas yog qis dua acrylic, nws lub hnub tsis kam zoo dua li cov ntaub ntuj fiber, tshwj xeeb tshaj yog tom qab iav, nws lub hnub tsis kam zoo heev, yuav luag sib piv rau acrylic. Tsis tas li ntawd, cov ntaub polyester muaj kev tiv thaiv zoo rau ntau yam tshuaj lom neeg, nrog me ntsis kev puas tsuaj los ntawm acid thiab alkali, thiab tsis ntshai pwm lossis kab.
Txawm li cas los xij, polyester fiber muaj dej nqus tsis zoo thiab tsis ua pa tau. Thaum hnav thaum lub caij ntuj sov, nws zoo li txhaws thiab txhaws. Qhov no feem ntau yog vim cov dej noo tsawg thiab ua pa tsis zoo ntawm polyester fibers piv rau cov fibers ntuj. Yog vim li cas hnav cov khaub ncaws polyester thaum lub caij ntuj sov ua rau peb tsis xis nyob thaum cov khaub ncaws lo rau peb daim tawv nqaij tom qab hws. Ntxiv mus, nws yooj yim nqus cov hmoov av thiab tsim hluav taws xob static. Thaum lub caij ntuj no, cua thiab xuab zeb muaj zog, thiab nws tuaj yeem xav tias hnav cov khaub ncaws polyester fiber yooj yim muaj plua plav, uas tsis tsuas yog ua rau tsis zoo nkauj xwb, tab sis kuj yog qhov tsis zoo tshaj plaws yog hluav taws xob static tsim. Tsis yog nws tsuas yog xav tias khaus xwb, tab sis yog tias nws yog ris, lawv kuj yuav lo rau daim tawv nqaij vim hluav taws xob static, poob tag nrho cov duab ntawm lub ris, uas tsis zoo nkauj heev. Nws yooj yim siv los ntawm cov tub lag luam tsis muaj kev ntseeg, tsim cov khoom zoo cov ntaubCov xov polyester nyuaj rau pom qhov sib txawv ntawm cov xov paj tiag tiag hauv cov qauv thiab tsos, thiab tau raug cov tub lag luam tsis muaj kev ntseeg siv los ua kom zoo dua ntawm lawv. Tsis tas li ntawd, ntau tus neeg siv khoom tsis nkag siab tias polyester fiber yog lub npe scientific ntawm polyester, thiab raug dag los ntawm lub npe tshiab ua cov ntaub zoo. Ib txhia txawm ntseeg tias nws yog ib qho derivative ntawm cov xov paj tiag tiag, ua rau nws nyuaj rau cov neeg siv khoom txhais cov ntsiab lus ntawm cov xov paj tiag tiag thiab polyester fiber.
