Softeners tuaj yeem muab faib ua ob hom: fatty acid derivatives thiab organic silicone roj. Lub qub yog ib txwm siv los ua softener, thaum lub tom kawg yog ib qho tshiab thiab tawm ntau yam. Txoj kev loj hlob ceev ntawm organosilicon softeners yog ceev heev, thiab ntau yam tshiab nrog ntau yam khoom thiab kev ua haujlwm tau tsim thiab tsim tawm tas li.
Vim lub softening nyhuv ntawm organosilicon softeners piv rau cov tsoos softeners, thiab qhov zoo dua durability ntawm lub finishing nyhuv. Yog li, nyob rau hauv kev siv ntawm textile mos finishing, nws tau nyob ib tug tseem ceeb txoj hauj lwm. Txawm li cas los xij, qhov tseeb vim tias nws cov kav ntev, ib zaug muaj qhov tsis xws luag dyeing uas yuav tsum tau kho ua ntej lawv tuaj yeem daws tau, los yog cov teeb meem tshwm sim los ntawm kev ua haujlwm tsis tu ncua thaum lub sij hawm kho softening, los yog xim hloov los ntawm kev kho softening, kho kho yuav nyuaj dua.
Fatty acid derivative softeners thiab organosilicon softeners feem ntau yog cationic, weakly cationic, los yog non-ionic nyob rau hauv cov nqe lus ntawm ionic zog. Yog li ntawd, nyob rau hauv daim ntawv thov uas compatibility raug tso cai, lawv feem ntau kho nyob rau hauv ib da dej nrog cov xim kho cov neeg ua hauj. Lawv cov dej da dej DH feem ntau ruaj khov thaum tsis muaj zog acidic; Qhov ntsuas kub tsim nyog rau kev ua cov da dej yog 30-45 cc. Tom qab softening kev kho mob, nws tsis yog lawm ntxuav, thiab tom qab ci, nws cov tshuaj tiv thaiv los ua ib tug zaj duab xis muaj ib tug ntau firmness. Yog tias qhov thaiv kev ua haujlwm tsis tau ceev faj, cov khoom siv silicone kuj tseem ua rau demulsification thiab roj bleaching teeb meem. Qee cov dyes uas yuav tsum tau kho softening nyob rau hauv lub tshuab dyeing, xws li cov khaub ncaws tiav, xov paj, xoob fibers, thiab lwm yam, kuj yog ib qho yooj yim mus tsub zuj zuj ntawm organic silicone roj tshuaj nyob rau hauv cov khoom tom qab siv ntev. Kev tu thiab kho nws yog qhov nyuaj dua li kev siv fatty acid zaj duab xis softeners.
Organic silicone roj yog ib qho tseem ceeb ntawm cov roj insoluble uas yuav tsum tau emulsified ua ntej nws yuav siv tau nyob rau hauv dyeing thiab finishing ntau lawm. Qee qhov hu ua dej-soluble silicone roj ntau yam tseem ceeb muaj kev ua haujlwm ntawm tus kheej emulsification hauv dej. Yog tias cov khoom thiab cov yam ntxwv ntawm cov roj silicone roj tsis tau ua tiav thaum siv, thiab cov txheej txheem yuav tsum tau ua los ntawm cov kev cai raug ua txhaum loj, qhov teeb meem ntawm demulsification thiab roj sib cais yuav tshwm sim.
Kev txheeb xyuas cov yam ntxwv physicochemical ntawm organosilicon softeners tuaj yeem ua tiav raws li hauv qab no:
a. Tus nqi DH ntawm kev ua haujlwm da dej ruaj khov yog 5-6.5.
b. Qhov ntsuas kub tsim nyog rau da dej ua haujlwm: 30-45 degree .
c. Ionicity: Feem ntau ntau yam yog cationic, ua raws li tsis yog-ionic, thiab qee hom yog anionic. (Piv cov teebmeem softness ntawm ntau yam, cationic ones feem ntau dominate.)
Ua kom tiav cov yam ntxwv thiab qhov sib xws ntawm cov xim kho cov neeg ua haujlwm thiab softeners. Thaum muab cov txheej txheem ruaj khov, cov txiaj ntsig kho tau zoo yuav ua tiav. Yog tias lawv thim rov qab, lawv tuaj yeem raug rhuav tshem thiab tshem tawm. Vim yog qhov siab tshaj plaws ntawm organosilicon softeners, yog tias organosilicon tuaj yeem kov yeej, tus so yuav raug daws.
