Nylon 6 fdy zoo denier xov paj nrog ib qho fiber ntau tsawg dua 1.1d muaj qhov muag muag thiab muag muag, smoothness thiab fullness, zoo huab cua permeability thiab siab elasticity.Nws yog ib qho khoom siv zoo tshaj plaws rau kev ua cov ntaub npuag.Txawm li cas los xij, qhov tsis sib xws dyeing los ntawm tensile deformation nyob rau hauv ib-kauj ruam spinning yog ib qho yooj yim mus ntsib.Peb yuav tiv thaiv qhov teeb meem no li cas?Peb kuj tseem yuav mloog Highsun cov lus qhia.
Cov dyestuff molecules yuav tsum nkag mus rau hauv thaj av amorphous ntawm nylon 6 fdy zoo denier xov paj rau dye seb nws yog masterbatch spinning lossis lig dip dyeing.Qhov hloov pauv ntawm cov amino pawg cov ntsiab lus hauv cov saw hlau molecular thiab qhov sib txawv ntawm cov qauv ntawm cov khoom sib txawv ntawm fiber ntau los yog hauv tib lub pob los ntawm tensile deformation yog ib qho yooj yim ua rau cov xim sib txawv.
Kev faib tawm ntawm spinning tiav rau ntawm qhov chaw fiber ntau tsis sib xws, thiab cov xim sib txawv yog qhov yooj yim tshwm sim nyob rau theem tom ntej ntawm dip dyeing.Nws yog qhov zoo los txhim kho cov permeability, lubricity thiab kub tsis kam ntawm cov roj.Tsis tas li ntawd, nrog cov roj sib npaug thiab cov roj qis dua, nplua denier pa6fdy fiber ntau yooj yim saturated nrog dej nqus, uas yog qhov tsim nyog los tshem tawm qhov tsis sib xws dyeing los ntawm qhov sib txawv ntawm cov dej ntawm sab hauv thiab sab nraud fiber ntau.
Nyob rau tib lub sijhawm, lub tog raj kheej lub tshuab qis dua yog qhov sib npaug, uas yog qhov tsim nyog rau kev tshem tawm cov kev cuam tshuam ntawm cov av noo ib puag ncig ntawm fiber ntau, txo cov fiber ntau sib txawv ntawm cov pob khoom sib txawv, thiab txo qhov "sib sib zog nqus" thiab "teeb" xim sib txawv tshwm sim. los ntawm lig dip dyeing.Rau lub hauv paus no, kev ua kom zoo ntawm cov txheej txheem spinning yog ib txoj hauv kev zoo los txhim kho dyeing evenness.
Fine denier nylon fdy yarn rau pej xeem siv muaj cov yam ntxwv ntawm nplua denier, loj cheeb tsam tshwj xeeb, ceev cua sov dissipation, tsis muaj zog tensile, yooj yim orientation, crystallization, thiab lwm yam. .Cov fluidity siab dua yuav tsum tau rau spinning chips.Spinning kub yog me ntsis siab dua li cov pa spinning, thiab qis cua tshuab ceev thiab spinneret daim duab piv yog qhov zoo los txhim kho dyeing uniformity.
Txawm li cas los xij, cov nyhuv ntawm kev tshem tawm dyeing unevenness yog pom tseeb dua los ntawm kev siv Highsun hauv-situ polymerized nylon 6-xim chips.Nyob rau hauv qhov chaw polymerized nylon 6-xim chips yog dub los ntawm polymerization, tsis zoo li masterbatch spinning, uas yuav tsum tau ntxiv cov khoom sib tov thiab phau ntawv ua haujlwm, yog li tshem tawm qhov txaus ntshai.
Nyob rau hauv-situ polymerized polyamide 6-xim nti spinning ua los ntawm cov nylon yarn tsum tsis muaj lig dip dyeing thiab xov, yog li tsis muaj dyeing unevenness tshwm sim los ntawm cov txheej txheem nyuaj xws li dip dyeing kub, dye leveling tus neeg saib xyuas thiab dye concentration.Hauv kev tswj hwm ntau lawm, kev nyab xeeb ntawm kev txhim kho dyeing uniformity yog siab dua.
Nyob rau hauv-situ polymerized nylon 6-xim nti spinning tsis yooj yim rau tawg.Lub neej kev pab cuam ntawm lub module tuaj yeem ncav cuag ntau dua 45-60 hnub, ntau dua li ntawm cov masterbatch spinning.High spinnability yog txoj hauv kev los txhim kho dyeing uniformity.Qhov tseem ceeb tshaj, cov xim nylon nti hauv-situpolymerized koom nrog hauv cov khoom siv polymerization, thiab kev faib tawm ntawm cov xim hauv cov nylon 6 molecular saw yog ntau yam sib xws, thiab dyeing uniformity ntawm spun fine denier filament yog deb zoo dua li tus tswv batch spinning zog. piv.
