Cov Txheej Txheem Dyeing Thiab Teeb Lace

Kev hloov pauv ntawm lub shrinkage ntawm lace ntaub yog qhov tshwm sim ntawm fiber ntau shrinkage los ntawm kev qaug zog ntawm lub zog ntawm macromolecules nyob rau hauv fiber. Qhov cuam tshuam thermal no yog qhov tsis hloov pauv, uas txawv ntawm" kev nthuav tawm thermal thiab cov ntawv cog lus" qhov tshwm sim ntawm cov khoom siv dav dav. Feem ntau, tsuas yog hluavtaws hluavtaws muaj cov thermal shrinkage, thiab lub zog nruab nrab ntawm cov macromolecules ntawm cov fibers ntuj thiab cov leeg ua dua tshiab yog qhov loj, thiab thermal shrinkage yuav tsis tshwm sim. Cov hluavtaws hluavtaws yog rhuab mus rau qee qhov kub, thiab cov kev ntxhov siab nyob hauv lub fiber ntau thaum ua khoom thiab molding yuav ua rau thermal ntsws. Lub thermal shrinkage tus nqi sib txawv nrog cov txheej txheem kho cua sov. Lub thermal shrinkage ntawm cov xov hluavtaws tsis zoo rau qhov wearability ntawm cov khoom tiav. Thaum lub thermal shrinkage ntawm cov fibers loj, qhov ruaj ntseg seem ntawm cov ntaub tsis zoo. Thaum lub tshav kub shrinkage ntawm lub fiber ntau tsis sib xws, cov ntaub yuav wrinkle thiab tsis sib xws. Thaum cov nplaim hluavtaws lossis nws cov ntaub ua kom kub siab tshaj qhov iav hloov qhov kub, qhov sib zog ntawm cov macromolecules sab hauv fiber ntau yuav tsawg zuj zus, thiab fiber ntau' s deformability yuav nce ntxiv. Yog tias qee qhov kev nruj nreem ntxiv txhawm rau txhawm rau txhawm rau txhawm rau hloov pauv, cov duab ntawm cov hluavtaws fiber ntau yuav ruaj khov nyob rau hauv kev tsim kho tshiab tom qab txias thiab tso tawm sab nraud quab yuam. Ntev npaum li qhov kub hauv kev siv tsis tshaj qhov ntsuas kub tshaj qhov teeb meem, cov duab ntawm cov tshuaj fiber lossis ntaub yuav tsis hloov pauv ntau. Cov cuab yeej no ntawm cov khoom siv hluavtaws hu ua thermoplasticity. Qhov ua tiav siv cov thermoplasticity ntawm lub fiber yog hu ua kev ua haujlwm kub. Ris tsho ironing yog ib hom kev ua kom tshav kub. Cov cua sov tso tawm kuj tseem tuaj yeem nqa tawm ntawm qhov ntsuas kub thiab tsis muaj qhov nro. Lub fiber ntau sai sai thiab tawm mus ua kom tshem tawm kev ntxhov siab sab hauv. Tom qab txias txias, qhov ruaj khov ntawm qhov loj me thiab cov duab ntawm cov fiber ntxiv nce. Cov txheej txheem ua no yog hu ua chaw so kom sov. Lub hauv paus tseem ceeb cuam tshuam rau kev cuam tshuam tshav kub kub yog qhov kub thiab lub sijhawm. Kev kho kom zoo rau lub tshav kub kub yuav txhim kho kom ruaj ntseg qhov ntev, elasticity thiab wrinkle tsis kam ntawm lace. Hauv cov txheej txheem tshav kub, cov hluavtaws lossis nws cov ntaub ua kom txias sai tom qab kev kho kub, thiab qhov chaw sib nrig ntawm cov lwg me me hauv cov fiber ntau tau khov sai thiab ruaj khov, tsim ntau qhov chaw amorphous, ua rau lub fiber lossis ntaub zoo softer thiab ntxiv ywj pheej. Tom qab cov ris tsho yog ironed thiab ua tiav, nws yuav tsum tau txias kom sai li sai tau kom tau txais cov qauv kev teeb tsa zoo. Yog tias nws txias maj mam ntev rau lub sijhawm ntev tom qab kev kho kub, qhov chaw sib luag ntawm cov lwg me me hauv cov fiber ntau tsis tuaj yeem kho tau sai. Ntxiv nrog rau qhov ploj ntawm qhov kev txiav tawm ntawm cov ntawv fiber ntau thiab cov ntaub, nws tseem yuav ua rau muaj qhov quaj crystallization tseem ceeb ntawm cov qauv sab hauv los ntawm fiber ntau, uas yuav txo qhov elasticity ntawm daim ntaub thiab ua rau lub zog tawv.

Cov hluavtaws hluavtaws nrog cov dej nqus zoo xws li nylon tuaj yeem txo qhov kev sib txuas ntawm cov macromolecules ntawm cov fiber ntau thiab ua kom nrau qhov tsis cuam tshuam ntawm cov kab sib txuas ntawm cov intermolecular, uas yog sib raug zoo rau cov nyhuv kub. Yog li ntawd, kev teeb tsa cov nyhuv ntawm chav lossis rhaub dej kub yog qhov zoo dua. Cov nyhuv ntawm kev ua kom sov tshav kub yog qhov zoo dua. Peb cov dyeing ib txwm yog ua los ntawm kev kub npau npau. Lub lace thiab ntaub zoo dua zoo meej tom qab kev teeb tsa.
