Textile softeners, raws li ib qho tseem ceeb ntawm kev ua tiav auxiliaries, tshuav lawv cov functionality rau lawv cov tshuaj muaj pes tsawg leeg. Lawv feem ntau yog tsim los ntawm qhov chaw- cov neeg ua haujlwm nquag thiab ntau yam haujlwm pabcuam. Cov qauv molecular sib txawv txiav txim siab lawv cov txheej txheem adsorption, kev xav ntawm tes, thiab kev siv ntau yam.Ib qho kev nkag siab zoo ntawm lawv cov khoom tseem ceeb pab ua kom tau txais kev ua tau zoo thiab kev sib txuam hauv kev tsim qauv thiab kev siv tswv yim.
Lub ntsiab tseem ceeb ntawm softeners yog surfactants, uas tuaj yeem muab faib ua cationic, anionic, nonionic, thiab amphoteric hom raws li lawv cov khoom ionic. Cationic softeners feem ntau ntev -chain alkyl quaternary ammonium compounds, xws li hexadecyltrimethylammonium chloride thiab dioctadecyldimethylammonium chloride. Lawv cov molecules muaj lipophilic ntev carbon saw ntawm ib kawg thiab ib tug zoo them quaternary ammonium pawg ntawm lwm yam. Cov qauv no tso cai rau lawv kom yooj yim tsim electrostatic adsorption nrog qhov tsis zoo ntawm cov khoom siv fiber ntau, taw qhia ua cov yeeb yaj kiab hloov tau yooj yim ntawm cov fiber ntau, txo cov coefficient ntawm kev sib txhuam ntawm fibers, muab cov ntaub mos mos thiab du, thaum tseem muaj qee yam tshuaj tiv thaiv kab mob thiab cov kab mob. Anionic softeners feem ntau suav nrog sulfonates, sulfates, thiab phosphates. Lawv cov molecules nqa cov nqi tsis zoo, thiab lawv tus cwj pwm adsorption yog cuam tshuam los ntawm fiber ntau tus nqi thiab dej hardness. Lawv feem ntau yog siv los ua tiav cov hluavtaws fibers uas tsim nrog anionic dye systems. Nonionic softeners, sawv cev los ntawm fatty cawv polyoxyethylene ethers, alkylphenol polyoxyethylene ethers, thiab hloov silicones, tsis muaj ionizing pawg. Lawv adsorb rau ntawm fiber ntau ntawm cov ntawv cog lus hydrogen thiab van der Waals rog, nthuav tawm cov tshuaj lom neeg ruaj khov thiab kev sib raug zoo nrog ntau lub koom haum. Lawv yog tshwj xeeb tshaj yog haum rau them nqi{10}}sensitive protein fibers thiab multi{11}}cov khoom xyaw. Amphoteric softeners muaj ob qho tib si zoo thiab tsis zoo cov chaw them nqi, xws li betaines thiab amino acid surfactants. Lawv daim ntawv adsorption tuaj yeem hloov kho raws li qhov sib txawv pH, txhim kho lawv cov kev hloov pauv mus rau ntau cov fibers thiab tswj kev ruaj ntseg hauv cov dej tawv, txo qhov kev pheej hmoo ntawm nag lossis daus.
Ntxiv nrog rau cov pob txha surfactant, softeners feem ntau tsim nrog ntau yam khoom siv pabcuam kom nthuav dav lawv cov kev ua tau zoo. Thickeners, xws li polymers lossis inorganic colloids, yog siv los kho cov viscosity ntawm cov kua dej ua haujlwm kom ntseeg tau tias daim ntawv thov tsis sib xws; preservatives inhibit microbial kev loj hlob thiab tiv thaiv emulsion deterioration; antioxidants ncua kev degradation ntawm lub ntsiab Cheebtsam thaum lub sij hawm cia thiab siab -kub ua; fragrances impart ib tug qab ntxiag tsw rau fabrics; qee cov khoom siv siab -kev ua tau zoo suav nrog cov khoom siv silicone lossis nanoparticles txhawm rau txhim kho smoothness, elasticity rov qab, thiab ntxuav.
Nrog rau kev nce qib ntawm cov tswv yim tsim ntsuab, kev ua phooj ywg ib puag ncig ntawm cov khoom tseem ceeb ntawm cov ntaub softeners tau txais kev saib xyuas ntxiv. Ib txwm ntev-chain alkyl quaternary ammonium ntsev, vim lawv cov biodegradability tsawg, tau maj mam hloov los ntawm cov kab, ceg, lossis ester- hloov cov cationic agents; nyob rau hauv nonionic softeners, renewable nroj tsuag - muab tau cawv polyoxyethylene ethers yog maj mam hloov alkylphenol polyoxyethylene ethers; silicone-raws li softeners yog trending rau qis-cyclic, siab-polymerization qauv los txo volatility thiab toxicity, ua tau raws li cov kev cai ntawm eco- textile qauv.
Zuag qhia tag nrho, cov khoom tseem ceeb ntawm textile softeners yog cov tshuab sib xyaw ua ke nyob ib ncig ntawm ntau yam surfactants, ntxiv los ntawm cov khoom siv ntxiv los ua haujlwm ua ke. Nws cov qauv molecular, tus yam ntxwv them nqi, thiab kev sib cuam tshuam txiav txim siab tus cwj pwm adsorption, tactile xav, thiab kev ua haujlwm ib puag ncig. Kev txheeb xyuas kev tshawb fawb thiab kev tsim qauv tsim nyog ntawm cov khoom siv no yog lub hauv paus tseem ceeb rau kev ua tiav qib siab - cov khoom muag zoo thiab kev txhim kho kom ruaj khov.
