Yuav daws qhov teeb meem ntawm qhov tsis sib xws ntawm spunbond nonwoven fabrics?

Dongguan Liansheng non-woven npuag chaw tsim tshuaj paus hais rau koj:

Yuav daws qhov teeb meem ntawm qhov tsis sib xws ntawm cov ntaub tsis-woven? Yog vim li cas rau uneven thickness ntawmspunbond non-woven fabricsnyob rau hauv tib txoj kev ua tej zaum yuav muaj xws li cov hauv qab no:

High shrinkage tus nqi ntawm fibers: Txawm hais tias nws yog cov pa fibers los yog tsawg melting point fibers, yog hais tias cov cua kub shrinkage tus nqi ntawm fibers yog siab dhau lawm, tsis sib xws thickness kuj yuav tshwm sim thaum lub sij hawm tsim cov ntaub ntawv uas tsis yog-woven vim yog shrinkage teeb meem.

Tsis tiav melting point fibers uas tsis muaj melting point: Lub ntsiab yog vim li cas rau tsis tiav melting point fibers yog tsis txaus kub. Rau cov ntaub uas tsis yog-woven nrog lub hauv paus hnyav, nws feem ntau tsis yooj yim kom muaj qhov kub tsis txaus. Txawm li cas los xij, rau cov khoom uas muaj qhov hnyav thiab tuab, tshwj xeeb yuav tsum tau them rau seb lawv puas txaus. Non-woven fabrics nyob rau ntawm cov npoo feem ntau yog thicker vim muaj cua sov txaus, thiab cov ntaub tsis-woven nyob rau hauv nruab nrab seem feem ntau yog thicker, Vim hais tias lub tshav kub yog yooj yim tsis txaus los ua ib tug nyias nyias non-woven fabrics.

Kev sib xyaw tsis sib xws ntawm cov fibers uas tsis tshua muaj melting point thiab cov pa fiber ntau: Cov fibers sib txawv muaj cov sib txawv cohesive rog. Feem ntau hais lus, tsawg melting point fibers muaj zog cohesive ntau dua thiab tsis yooj yim dispersed dua li cov pa fibers. Yog tias cov fibers uas tsis tshua muaj melting point tsis sib npaug, cov khoom uas tsis tshua muaj melting point fiber ntau tsis tuaj yeem tsim cov qauv network txaus, thiab cov ntaub uas tsis yog-woven yog ruaj dua, ua ib qho tshwm sim tuab nyob rau hauv cov cheeb tsam uas muaj cov ntsiab lus tsawg melting point fiber ntau.

Qhov teeb meem ntawm hluav taws xob zoo li qub generated thaum lub sij hawm tsim khoomspunbond nonwoven ntaubFeem ntau yog tshwm sim los ntawm cov dej noo tsawg hauv cov huab cua thaum cov fibers thiab koob fabrics tuaj rau hauv kev sib cuag, uas tuaj yeem muab faib ua cov ntsiab lus hauv qab no:

1.Cov huab cua qhuav dhau lawm thiab cov av noo tsis txaus.

2.Thaum tsis muaj roj ntawm cov fiber ntau, tsis muaj cov tshuaj tiv thaiv zoo li qub ntawm cov fiber ntau. Vim tias cov dej noo rov qab ntawm polyester paj rwb yog 0.3%, qhov tsis muaj cov tshuaj tiv thaiv zoo li qub ua rau muaj hluav taws xob zoo li qub thaum tsim khoom.

3.SILICONE polyester paj rwb, vim muaj cov qauv molecular tshwj xeeb ntawm tus neeg sawv cev oiling, yuav luag tsis muaj dej ntawm tus neeg sawv cev oiling, ua rau nws muaj feem cuam tshuam rau hluav taws xob zoo li qub thaum tsim khoom. Feem ntau, qhov smoothness ntawm tes xav tau ncaj qha proportional rau hluav taws xob zoo li qub, thiab lub smoother ntawm SILICONE paj rwb, ntau dua qhov hluav taws xob zoo li qub.

4.Qhov plaub txoj kev tiv thaiv hluav taws xob zoo li qub tsis yog siv los ua kom cov av noo hauv kev tsim khoom, tab sis kuj yog ib txoj haujlwm tseem ceeb hauv kev tshem tawm cov roj tsis muaj paj rwb thaum lub sij hawm noj cov paj rwb.
