Organic silicone softener originated nyob rau hauv 1950s.Thiab nws txoj kev loj hlob tau dhau los ntawm plaub theem.
1.Thawj tiam ntawm silicone softener
Xyoo 1940, tib neeg pib siv dimethyldichlorosilance los ua kom tsis muaj zogntaubthiab tau txais qee yam kev siv dej tsis zoo.Xyoo 1945, Elliott ntawm American General Electric Company (GE) tau ntim cov fibers hauv cov tshuaj alkaline aqueous nrog sodium methyl silanol.Tom qab cua sov, cov fiber ntau muaj cov nyhuv dej tsis zoo.
Nyob rau hauv thaum ntxov 50s, American Dow Corning Company pom tias fabrics kho los ntawm polysiloxane nrog Si-H muaj zoo waterproof nyhuv thiab zoo huab cua permeability.Tab sis qhov kev xav ntawm tes tsis zoo thiab kuj yog cov yeeb yaj kiab silicone yog tawv, nkig thiab yooj yim poob.Tom qab ntawd nws tau siv ua ke nrog polydimethylsiloxane (PDMS).Muaj tsis tau tsuas yog tau zoo waterproof nyhuv tab sis kuj muag tes zoo lawm.Tom qab ntawd, txawm hais tias cov khoom siv silicone thoob plaws ntiaj teb tau tsim kho sai thiab npog ntau yam, lawv tau koom nrog cov khoom sib xyaw ntawm dimethyl.silicone roj, uas tau sau npe hu ua cov khoom siv roj silicone.Lawv yog thawj tiam ntawm textile silicone softener.
Thawj tiam ntawm silicone softeners ncaj qha emulsified silicone roj los ntawm txhua yam emulsification.Tab sis vim tias cov roj silicone nws tus kheej tsis muaj cov pab pawg ua haujlwm, uas tsis tuaj yeem khi zoo rau cov ntaub thiab tsis tuaj yeem ntxuav.Yog li nws yuav tsis ua tiav cov txiaj ntsig zoo thaum nws siv ib leeg.
2.Qhov thib ob tiam ntawm silicone softener
Txhawm rau kov yeej qhov tsis txaus ntawm thawj tiam ntawm silicone softener, cov kws tshawb fawb tau pom lub cim thib ob ntawm silicone emulsion nrog hydroxyl caps.Cov softener mas muaj hydroxyl silicone roj emulsion thiab hydrogen silicone roj emulsion, uas yuav tsim ib tug network crosslinking qauv ntawm cov ntaub nto nyob rau hauv lub xub ntiag ntawm hlau catalyst, imparting fabrics zoo softness, washability thiab stability.
Tab sis vim nws muaj ib qho kev ua haujlwm thiab yooj yim demulsified thiab ntab roj, nws tau hloov los ntawm peb tiam ntawm silicone softener ua ntej nws tau dav siv.
3.Qhov thib peb tiam ntawm silicone softener
Peb tiam ntawmsilicone softenertau tsim qhov nrawm tshaj plaws ntawm cov uas tshwm sim hauv xyoo tas los no.Nws qhia lwm cov ntu lossis cov pab pawg ua haujlwm rau hauv lub ntsiab lossis sab chains ntawm polysiloxane, xws li polyether pawg, epoxy pawg, cawv hydroxyl pawg, amino pawg, carboxyl pawg, ester pawg, sulfhydryl pawg, thiab lwm yam. Nws tuaj yeem txhim kho softness thiab kev ua tau zoo ntawm txhua yam ntawm fabrics.Tsis tas li ntawd tso siab rau cov pab pawg, nws tuaj yeem faib cov ntaub sib txawv.
Tab sis feem ntau tiam thib peb ntawm silicone softener yuav tsum tau ua ke nrog monofunctional polysiloxane kom ua tiav cov txiaj ntsig xav tau.Nws yog ib qho nyuaj los tswj tus nqi compounding, uas cuam tshuam rau kev tsim khoom thiab kev siv.
4.Qhov thib plaub tiam ntawm silicone softener
Lub cim thib plaub ntawm silicone softener yog ntxiv hloov lub cim thib peb ntawm silicone softener raws li qhov yuav tsum tau ua tiav ntawm cov ntaub.Qhov ntawd tau qhia ntau pab pawg, uas tuaj yeem ua tau raws li txhua qhov kev xav tau ntawm cov ntaub tsis muaj kev sib xyaw.
Fabrics kho los ntawm kev hloov kho silicone softener nrog ntau yam ntawm cov pab pawg neeg muaj kev txhim kho ntau dua hauv softness, washability, elasticity thiab hydrophilicity, thiab lwm yam. tam sim no.
