Vim li cas thiaj yuav tsum Polyester xov paj thiab ntaub Pretreatment yuav tsum tau greased?

Kev kho ntawm polyester yarn los yog ntaub feem ntau yog raws li cov roj tshem tawm, vim hais tias polyester yarn yuav muab ntxiv rau cov roj spinning, yog li, cov roj dav dav siv hauv polyester yarn spinning roj yog dab tsi? Cov hauv qab no yog hais txog polyester spinning roj.
Muaj ntau hom polyester filament roj, suav nrog POY, DTY, pa spinning, stretching, deforming thiab industrial silk oil. Lawv muaj peev xwm ua si bunching, lubrication, txo kev sib txhuam coefficient, antistatic thiab lwm yam, tab sis kuj muaj lawv tus kheej tshwj xeeb zog thiab adaptability, txawm rau tib hom filament, vim hais tias ntawm cov khoom siv thiab cov txheej txheem tom qab yog txawv, cov yam ntxwv ntawm tus neeg sawv cev roj yuav tsum tau sib txawv.
Polyester filament roj tuaj yeem muab faib ua cov roj spinning thiab cov roj tiav, cov yam ntxwv ntawm cov roj yog tib yam, tab sis kev ua haujlwm ntawm cov roj spinning yog siab dua li cov roj tiav.
Ua ntej, qhov kev ua tau zoo ntawm tus neeg sawv cev roj
1, smoothness, los yog lubrication, yog qhov tseem ceeb ntawm kev sib txhuam cov yam ntxwv ntawm tus neeg sawv cev roj.
Cov coefficient ntawm kev sib txhuam zoo li qub (μs) thiab cov coefficient ntawm kev sib txhuam dynamic (μd) ntawm silk thiab silk (F / F), silk thiab hlau (F / M) thiab silk thiab roj hmab (F / R) feem ntau tau qhia. Feem ntau hais lus, tom qab cov roj zoo dua nyob rau ntawm cov lo lo ntxhuav, qhov sib txhuam zoo li qub ntawm F / F yuav tsum loj, kom cov khoom sib txuas ntawm cov lo lo ntxhuav zoo, winding molding yog qhov zoo, thiab cov cuab yeej unwinding zoo heev. Tsis muaj qhov tshwj xeeb uas yuav tsum tau muaj ntawm cov kev sib txhuam dynamic ntawm F / F, tab sis cov txhob lo lo ntxhuav yog ib qho yooj yim rau deform yog tias nws swb thaum lub sij hawm tsis tseeb twist deformation.
