Cov laj thawj rau qhov tsis sib xws ntawm cov ntaub tsis-woven thaum tsim khoom
Lub shrinkage tus nqi ntawm fibers yog kuj siab
Txawm hais tias nws yog cov pa fiber ntau lossis cov ntsiab lus melting tsawg, yog tias qhov thermal shrinkage tus nqi ntawm cov fibers yog siab, nws yog ib qho yooj yim ua rau cov thickness tsis sib xws thaum lub sij hawm tsim cov ntaub ntawv uas tsis yog-woven vim muaj teeb meem shrinkage.
Tsis tiav melting ntawm tsawg melting point fibers
Qhov xwm txheej no feem ntau yog vim qhov kub tsis txaus. Rau cov ntaub uas tsis yog-woven nrog lub hauv paus hnyav, nws feem ntau tsis yooj yim los ntsib qhov teeb meem ntawm qhov kub tsis txaus, tab sis rau cov khoom uas muaj lub hauv paus hnyav thiab tuab tuab, tshwj xeeb yuav tsum tau them rau seb qhov kub thiab txias txaus. Piv txwv li, cov ntaub tsis-woven ntawm ntug feem ntau yog thicker vim muaj cua sov txaus, thaum cov ntaub tsis-woven hauv nruab nrab tuaj yeem tsim cov ntaub nyias nyias vim tsis muaj cua sov.
Kev sib xyaw tsis sib xws ntawm cov fibers qis melting point thiab cov pa fibers hauv paj rwb
Vim muaj cov fibers sib txawv uas muaj zog sib txawv, qhov qis melting point fibers feem ntau muaj zog tuav ntau dua li cov pa fiber ntau. Yog hais tias qhov tsawg melting point fibers yog unevenly dispersed, qhov chaw nrog qis cov ntsiab lus yuav tsis muaj peev xwm tsim ib tug txaus mesh qauv nyob rau hauv lub sij hawm, uas ua rau thinner non-woven fabrics tsim, thiab thicker sawv daws yuav piv rau cov cheeb tsam uas muaj siab melting point fiber ntau.
Lwm yam
Tsis tas li ntawd, cov khoom siv kuj tseem tuaj yeem ua rau tsis sib xws ntawm cov ntaub tsis-woven. Piv txwv li, seb qhov ceev ntawm lub web nteg tshuab yog qhov ruaj khov, txawm tias qhov kev them nyiaj ceev raug kho kom raug, thiab seb lub tshuab kub stamping raug kho kom raug zoo li cas yuav cuam tshuam rau cov thickness uniformity ntawm cov ntaub tsis-woven.
Yuav daws li cas
Txhawm rau daws cov teeb meem no, cov neeg tsim khoom yuav tsum xyuas kom meej tias qhov shrinkage tus nqi ntawm fibers yog tswj nyob rau hauv ib tug tsim nyog ntau yam, xyuas kom meej melting uas tsis muaj melting point fibers, kho qhov sib tov piv thiab uniformity ntawm fibers, thiab tshuaj xyuas thiab kho cov khoom siv kom ruaj khov thiab raug.
Thov nco ntsoov tias cov chaw tsim khoom sib txawv thiab hom tsis-woven fabrics yuav ntsib cov teeb meem tshwj xeeb thaum lub sijhawm tsim khoom. Yog li ntawd, thaum daws qhov teeb meem ntawm qhov tsis sib xws ntawm cov ntaub tsis sib xws, cov kev ntsuas sib xws yuav tsum tau ua raws li qhov xwm txheej tshwj xeeb, thiab cov kws tshaj lij hauv cov haujlwm tseem ceeb yuav tsum tau sab laj rau cov lus qhia tshaj lij.
Dab tsi yog vim li cas rau hluav taws xob zoo li qub thaum tsim khoom?
1. Cov yam ntxwv sab nraud tuaj yeem yog vim huab cua qhuav heev thiab cov av tsis txaus.
2.Thaum tsis muaj cov tshuaj tiv thaiv zoo li qub ntawm cov fiber ntau, cov dej noo rov qab ntawm polyester paj rwb yog 0.3%, thiab qhov tsis muaj cov tshuaj tiv thaiv zoo li qub tau ua rau cov khoom siv hluav taws xob zoo li qub thaum lub sij hawm cov ntaub tsis muaj ntaub.
3. Cov ntsiab lus roj tsawg hauv fibers thiab cov ntsiab lus tsis tshua muaj hluav taws xob tuaj yeem tsim hluav taws xob zoo li qub.
4. Ntxiv nrog rau kev ua kom cov khoom tsim tawm, nws tseem ceeb heev kom tshem tawm cov paj rwb tsis muaj roj kom zoo thaum lub sij hawm pub mis kom tsis txhob muaj hluav taws xob zoo li qub.
Yuav ua li cas yog vim li cas rau uneven softness thiab hardness ntawm non-woven fabrics?
1.Vim qhov sib xyaw tsis sib xws ntawm cov ntsiab lus melting tsawg thiab cov pa fiber ntau, cov khoom uas muaj cov ntsiab lus qis dua melting point nyuaj, thaum cov ntsiab lus qis dua yog softer.
2. Tsis tas li ntawd, tsis tiav melting point fibers uas tsis muaj melting point kuj yooj yim ua rau qhov tshwm sim ntawm softer non-woven fabrics.
3. Lub siab shrinkage tus nqi ntawm fibers kuj tuaj yeem ua rau tsis sib xws softness thiab hardness ntawm non-woven fabrics.
