Sodium Dichloroisocyanurate (NaDCC luv luv) yog cov tshuaj tua kab mob zoo, nyab xeeb thiab dav siv tshuaj tua kab mob. Nrog nws cov chlorination zoo heev, NaDCC tau dhau los ua tus neeg sawv cev kho mob zoo heev rau kev tiv thaiv cov ntaub plaub.
Qhov tsim nyog ntawm wool shrinkage tiv thaiv
Wool yog lub ntuj muaj fiber ntau nrog cov yam ntxwv ntawm softness, warmth tuav thiab zoo hygroscopicity. Txawm li cas los xij, ntaub plaub yog qhov ua rau shrinking thaum ntxuav los yog ntub dej rubbed, uas hloov nws qhov loj thiab qhov tsos. Qhov no yog vim hais tias saum npoo ntawm ntaub plaub fibers yog them nrog ib txheej ntawm keratin nplai. Thaum raug dej, cov nplais yuav swb thiab sib txuas, ua rau cov fibers entangle thiab ntsws. Yog li ntawd, kev tiv thaiv shrinkage dhau los ua ib feem tseem ceeb ntawm cov txheej txheem wool textile processing.
Cov yam ntxwv tseem ceeb ntawm sodium dichloroisocyanurate
NaDCC, raws li cov organic chlorine compound, muaj ob chlorine atoms thiab ib lub nplhaib isocyanuric acid nyob rau hauv nws cov qauv molecular. NaDCC tuaj yeem tso cov kua qaub hypochlorous (HOCl) hauv dej, uas muaj zog oxidizing zog thiab tshuaj tua kab mob zoo heev. Hauv kev ua textile, chlorination ntawm NaDCC tuaj yeem hloov kho cov qauv ntawm cov ntaub plaub zoo. Li no txo los yog tshem tawm cov nyiam ntawm cov ntaub plaub fibers kom xav tias shrinkage.
Kev siv lub hauv paus ntsiab lus ntawm NaDCC hauv kev tiv thaiv wool shrinkage
Lub hauv paus ntsiab lus ntawm NaDCC hauv kev tiv thaiv wool shrinkage feem ntau yog raws li nws cov yam ntxwv chlorination. Lub hypochlorous acid tso tawm los ntawm NaDCC tuaj yeem hnov mob nrog cov keratin nplai ntawm cov ntaub plaub los hloov nws cov qauv tshuaj. Tshwj xeeb, hypochlorous acid dhau los ua cov tshuaj tiv thaiv oxidation nrog cov protein nyob rau saum npoo ntawm cov ntaub plaub, ua rau cov nplai txheej smoother. Nyob rau tib lub sijhawm, kev sib txhuam ntawm cov nplais tsis muaj zog, txo qhov muaj peev xwm ntawm wool fibers hooking ib leeg. Nws tuaj yeem ua tiav kev tiv thaiv shrinkage thaum tswj cov khoom qub ntawm cov ntaub plaub. Tsis tas li ntawd, NaDCC muaj zoo solubility nyob rau hauv dej, cov tshuaj tiv thaiv txheej txheem kuj ruaj khov, thiab nws cov khoom decomposition yog ib puag ncig tus phooj ywg.
Qhov zoo ntawm sodium dichloroisocyanurate
Lub neej txee ntev
① Cov khoom siv tshuaj ntawm sodium dichloroisocyanurate ruaj khov thiab nws tsis yooj yim rau decompose ntawm chav tsev kub. Nws yuav tsis deteriorate txawm tias khaws cia ntev. Cov ntsiab lus ntawm cov khoom xyaw nquag tseem nyob ruaj khov, ua kom cov nyhuv tua kab mob.
② Nws tiv taus qhov kub thiab txias thiab yuav tsis decompose thiab inactivate thaum kub-kub tshuaj tua kab mob thiab kom tsis muaj menyuam, thiab tuaj yeem tua tau ntau yam kab mob.
③ Sodium dichloroisocyanurate muaj zog tiv thaiv sab nraud ib puag ncig xws li lub teeb thiab cua sov, thiab tsis yooj yim cuam tshuam los ntawm lawv thiab ua tsis tau zoo.
Cov khoom zoo heev no ua rau sodium dichloroisocyanurate cov tshuaj tua kab mob uas tsim nyog rau kev khaws cia thiab siv tau ntev, thiab tau siv dav hauv ntau yam xws li kev kho mob, zaub mov, thiab kev lag luam.
Yooj yim rau kev khiav lag luam
Kev siv NaDCC yog qhov yooj yim thiab tsis tas yuav siv cov cuab yeej nyuaj lossis cov txheej txheem tshwj xeeb. Nws muaj cov dej zoo solubility thiab tuaj yeem ncaj qha rau hauv kev sib cuag nrog cov ntaub plaub rau cov txheej txheem kev kho mob tas mus li lossis tsis sib xws. NaDCC muaj qhov ntsuas kub tsis tshua muaj qhov xav tau thiab tuaj yeem ua tau zoo shrinkage-proofing ntawm chav tsev kub lossis nruab nrab kub. Cov yam ntxwv no yooj yim heev rau kev ua haujlwm.
Wool kev ua tau zoo tseem zoo
NaDCC muaj cov nyhuv oxidation me me, uas zam dhau oxidative puas tsuaj rau cov ntaub plaub. Cov ntaub plaub kho tau tuav nws qhov qub softness, elasticity thiab gloss, thaum zoo tiv thaiv qhov teeb meem ntawm felting. Qhov no ua rau NaDCC yog ib qho zoo tagnrho cov ntaub plaub shrinkage-proofing tus neeg saib xyuas.
Cov txheej txheem ntws ntawm NaDCC wool shrinkage-proofing kho
Txhawm rau kom ua tiav cov txiaj ntsig zoo tshaj plaws wool shrinkage-proofing, cov txheej txheem kev kho mob ntawm NaDCC yuav tsum tau ua kom zoo raws li cov ntaub ntawv sib txawv thiab cov kev cai tsim khoom. Feem ntau hais lus, cov txheej txheem ntws ntawm NaDCC hauv wool shrink-proof kho yog raws li nram no:
Kev kho mob ua ntej
Wool yuav tsum tau ntxuav ua ntej kev kho mob kom tshem tawm cov av, roj thiab lwm yam impurities. Cov kauj ruam no feem ntau suav nrog kev ntxuav nrog tshuaj ntxuav me me.
Kev npaj cov tshuaj NaDCC
Raws li lub thickness ntawm cov ntaub plaub fiber ntau thiab cov kev xav tau, ib qho kev xav tau ntawm NaDCC aqueous tov yog npaj. Feem ntau, qhov concentration ntawm NaDCC yog tswj los ntawm 0.5% thiab 2%, thiab qhov tshwj xeeb concentration tuaj yeem hloov kho raws li qhov nyuaj ntawm kev kho cov ntaub plaub thiab lub hom phiaj.
Kev kho chlorine
Wool yog tsau rau hauv cov tshuaj uas muaj NaDCC. Chlorine selectively tawm tsam cov nplai txheej ntawm cov ntaub plaub fiber ntau, txo nws cov shrinkage. Cov txheej txheem no yuav tsum muaj kev tswj xyuas qhov kub thiab lub sijhawm kom tsis txhob ua rau cov ntaub plaub. Qhov kev kho mob dav dav yog tswj ntawm 20 txog 30 degrees Celsius, thiab lub sijhawm kho yog 30 mus rau 90 feeb, nyob ntawm seb cov thickness fiber ntau thiab kev kho mob yuav tsum tau ua.
Neutralization
Txhawm rau tshem tawm cov chlorides seem thiab tiv thaiv kev puas tsuaj ntxiv rau cov ntaub plaub, cov ntaub plaub yuav tau txais kev kho mob tsis zoo, feem ntau yog siv cov tshuaj tua kab mob los yog lwm yam tshuaj los ua kom tsis muaj cov tshuaj chlorine.
Yaug
Cov ntaub plaub uas kho tau yuav tsum tau muab yaug nrog dej kom tshem tawm cov tshuaj seem.
Ua tiav
Txhawm rau kho qhov kev xav ntawm cov ntaub plaub, ua kom cov gloss thiab softness, kho softening lossis lwm yam haujlwm tiav.
Qhuav
Thaum kawg, cov ntaub plaub tau qhuav kom ntseeg tau tias tsis muaj cov dej seem seem kom tsis txhob muaj cov kab mob loj hlob los yog pwm.
Sodium dichloroisocyanurate (NaDCC), uas yog ib qho zoo thiab ib puag ncig tus phooj ywg wool shrink-proof kho tus neeg saib xyuas, yog maj mam hloov cov tshuaj chlorination ib txwm siv nrog nws cov kev ua tau zoo chlorination thiab ib puag ncig tus phooj ywg. Los ntawm kev siv tsim nyog ntawm NaDCC, wool textiles tuaj yeem tsis tsuas yog tiv thaiv kev hnov lus zoo, tab sis kuj tswj tau qhov muag, elasticity thiab ntuj luster, ua rau lawv muaj kev sib tw hauv kev ua lag luam.
