Lo lus "shrinkage" txhais tau tias yog kev hloov pauv ntawm qhov loj ntawm daim ntaub lossis khaub ncaws. Qhov kev hloov pauv no tuaj yeem yog qhov zoo (loj hlob lossis ntev) lossis tsis zoo (shrinking) rau qhov ntev, dav thiab tuab ntawm daim ntaub. Txawm hais tias qhov tuab ntawm daim ntaub kuj hloov pauv vim yog kev ua thiab siv, qhov no feem ntau tsis suav tias yog teeb meem. Hauv daim ntaub paj rwb, shrinkage yog qhov poob ntawm qhov ntev thiab / lossis qhov dav. Hauv cov khaub ncaws, shrinkage tsis yog tsuas yog cuam tshuam nrog kev hloov pauv ntawm qhov loj ntawm daim ntaub, tab sis kuj tuaj yeem cuam tshuam nrog lwm yam xws li fraying ntawm seams, looping, thiab qhov haum ntawm daim ntaub.
Kev ntsws yog cov txheej txheem uas ua rau daim ntaub me dua li nws qhov loj thawj, feem ntau yog vim yog cov txheej txheem ntxhua khaub ncaws. Cov ntaub paj rwb muaj ob qhov tsis zoo tseem ceeb: Nws ntsws thiab ntsws thaum ntxuav tom qab. Txawm li cas los xij, muaj cov ntaub uas tiv taus kev ntsws ntau dua. Cov xov hluavtaws xws li polyester lossis nylon feem ntau ntsws tsawg dua li lwm tus, tab sis tsis tiv taus kev ntsws 100%.
Hom kev ntsws ntawm cov ntaub:
1, Kev tsim kho shrinkage:
Tom qab ib daim ntaub paj rwb tau tsim los ntawm lub tshuab xaws lossis tshuab ntaus ntaub, nws tau txais cov yam ntxwv tshwj xeeb rau kev tsim kho ntawm cov xov paj uas siv. Cov yam ntxwv lossis cov xwm txheej no hu ua lub xeev nyoos thiab tuaj yeem kuaj xyuas ntau yam ntxwv, suav nrog kev ntsws. Hom kev ntsws ntsuas ntawm theem no yog txhais tias yog kev ntsws tsim kho, uas yog qhov ntau ntawm kev hloov pauv ntawm cov ntaub raws li cov qauv tsim siv los ua daim ntaub. Kev ntsws ntawm cov qauv ntsuas tom qab tsim tab sis ua ntej cov txheej txheem tom qab.
2, Ua tiav kev ntsws:
Cov txheej txheem zas xim thiab ua tiav thiab cov txheej txheem tsim khaub ncaws cuam tshuam rau qhov loj ntawm cov khoom. Qee cov txheej txheem muaj kev cuam tshuam loj dua lwm tus.
Cov kauj ruam no ua rau kev ua cov ntaub shrinkage, uas tuaj yeem txhais tau tias yog kev hloov pauv ntawm qhov loj me uas cov txheej txheem ntxiv rau lossis rho tawm ntawm qhov shrinkage ntawm cov ntaub, yog li hloov pauv qhov seem shrinkage. Ob qho tib si ntev thiab dav qhov ntev raug cuam tshuam, thiab cov ntaub tuaj yeem ncab thiab compacted. Feem ntau, kev ua cov ntaub ntub dej ncab qhov ntev thiab txo qhov dav. Qee qhov ntawm qhov shrinkage no yog elastic shrinkage thiab tuaj yeem rov qab tau yooj yim; txawm li cas los xij, qee qhov kev hloov pauv ntawm qhov ntev tsis tuaj yeem rov qab tau vim tias cov kev txwv elastic ntawm cov ntaub tau dhau thaum lub sijhawm tsim khoom.
3, Kev ntswj elastic:
Qhov elastic shrinkage yog qhov kev hloov pauv ntawm qhov loj ntawm daim ntaub uas yog los ntawm lub peev xwm ntawm daim ntaub kom so tau yooj yim hauv qab kev ntxhov siab uas tsim tawm thaum lub sijhawm tsim khoom thiab lwm yam kev kho mob.
4, Kev ziab kom qhuav:
Kev ziab khaub ncaws me me yog qhov hloov pauv ntawm qhov loj ntawm daim ntaub uas tshwm sim los ntawm "kev o" ntawm cov fibers, cov xov paj thiab cov qauv thaum lub sijhawm ziab. Cov qauv no me me ntawm nws tus kheej vim yog lub cev ntawm kev ziab. Cov txheej txheem txuas ntxiv thaum lub sijhawm zas xim thiab kev npaj ziab feem ntau ncab qhov ntev thiab ncab lossis txo qhov dav, qee zaum mus dhau lawv qhov elasticity, hloov qhov ntev so.
Kuj tseem muaj ob hom kev ntsws uas tshwm sim thaum ntxuav: Hauv qhov ntev thiab Hauv qhov dav.
Feem ntau yuav kos ib cheeb tsam plaub fab rau ntawm cov ntaub uas ntsws thiab ntsuas. Cov ntaub uas muaj cim yuav raug rhaub hauv dej tshiab hauv lub voj voog ntxuav rau 30 feeb, centrifuged thiab cua qhuav. Qhov loj ntawm cov plaub fab yuav raug ntsuas yam tsis tau ironing cov ntaub qhuav, thiab txiav txim siab qhov ntsws. Cov ntaub uas haum zoo yuav tsum muaj qhov ntsws seem tsis pub ntau tshaj 1%.
Peb vam tias tsab xov xwm no yuav pab tau koj. Mus saib peb lub vev xaib kom paub ntau ntxiv txog cov ntaub thiab xov xwm kev lag luam. Yog tias muaj lus nug, thov tsis txhob yig tiv tauj peb.
