Qhov hu ua mos thiab xis tuav ntawm textiles yog ib qho kev xav tau los ntawm kev kov cov ntaub nrog koj cov ntiv tes.Thaum tib neeg kov cov ntaub, lawv cov ntiv tes swb thiab rub ntawm cov fibers, textile tes zoo nkaus li thiab softness muaj ib qho kev sib raug zoo nrog cov coefficient ntawm dynamic kev sib txhuam ntawm cov fibers.Tsis tas li ntawd, lub fluffiness, plumpness thiab elasticity kuj yuav ua rau tes zoo li ntaub mos.Nws qhia tau hais tias covtes kev xavmuaj feem xyuam rau cov qauv saum npoo ntawm cov fiber ntau.Piv txwv li, siv surfactant softeners.Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm softeners feem ntau xav tau piav qhia hauv ob txoj hauv kev.Nws yog ib qho yooj yim rau surfactants kom muaj oriented adsorption ntawm cov fibers.Txawm hais tias cov surfactants yog adsorbed rau ntawm cov khoom sib xws txo qhov nro ntawm qhov chaw, qhov chaw fiber ntau yog qhov nyuaj rau kev nthuav dav.Thiab textiles fibers yog tsim los ntawm linear macromolecule nrog loj heev tshwj xeeb cheeb tsam thiab elongated zoo heev, uas nws molecular saw muaj zoo yooj.Tom qab absorbing surfactants, qhov nro saum npoo yog txo, uas ua rau cov fibers yog ib qho yooj yim mus nthuav nto thiab elongate qhov ntev.Yog li ntawd cov ntaub yuav fluffy, plump, elastic thiab mos.Qhov muaj zog ntawm adsorption ntawm surfactant ntawm fiber ntau thiab qhov txo qis ntawm fiber ntau qhov nro, cov nyhuv mos yog pom tseeb dua.Cationic surfactants tuaj yeem ua rau muaj zog adsorbed ntawm fiber ntau los ntawm electrostatic quab yuam (feem ntau fibers muaj qhov tsis zoo ntawm tus nqi).Thaum cov pab pawg cationic ntsib cov fiber ntau thiab cov hydrophobic pawg ntsib cov huab cua, cov nyhuv ntawm qhov txo qis fiber ntau qhov nro yog ntau dua.
Txoj kev nqus ntawm surfactants ntawm fiber ntau ua ib zaj duab xis nyias ntawm cov pab pawg hydrophobic kom zoo zoo sab nraud, uas ua rau kev sib txhuam ntawm fibers tshwm sim ntawm pawg hydrophobic uas swb tawm tsam ib leeg.Vim yog oiliness ntawm pawg hydrophobic, qhov sib txhuam coefficient yog txo qis heev.Thiab cov saw hydrophobic pawg yog ntev dua, nws swb yooj yim dua.Qhov txo qis ntawm kev sib txhuam coefficient kuj txo cov flexural modulus thiab compressing quab yuam ntawm cov ntaub, yog li cuam tshuam raukov.Nyob rau tib lub sijhawm, qhov txo qis ntawm kev sib txhuam coefficient ua rau nws yooj yim rau cov yarns swb thaum cov ntaub raug rau sab nraud quab yuam, yog li ntawd qhov kev ntxhov siab yog tawg thiab lub zog tearing zoo tuaj.Los yog thaum lub sij hawm ua hauj lwm, fibers raug quab yuam muaj zog yuav rov qab mus rau lub xeev so yooj yim, ua rau tus kov.Thaum tib neeg kov cov fibers, static kev sib txhuam coefficient plays lub luag hauj lwm tseem ceeb hauv softness ntawm ntaub.Tab sis kuj hais lus, qhov muag muag ntawm cov fibers muaj feem cuam tshuam nrog kev txo qis ntawm kev sib txhuam coefficient.
Softening finishing tus neeg saib xyuas feem ntau yog hais txog ib qho chaw uas tuaj yeem adsorbed ntawm cov fiber ntau thiab du nto ntawm fiber ntau, ua rau cov softness ntawm fiber ntau.Tam sim no, muaj ob hom kev siv ntausoftening tus neeg sawv cev, raws li surfactants thiab high-molecular softening agents.High-molecular softening agents feem ntau suav nrog silicone softeners thiab polyethylene emulsions.
