Txij li thaum lawv nkag mus rau hauv kev lag luam ntau lawm hauv xyoo 1940, surfactants tau siv dav dav thiab tau qhuas tias yog "MSG ntawm kev lag luam." Surfactant molecules muaj amphiphilic cov yam ntxwv, ua rau lawv yuav tsum tau ua kom muaj nyob rau ntawm cov kev daws teeb meem aqueous. Ua raws li qhov sib piv ntawm hydrophhilic rau hydrophobic ntu thiab cov qauv molecular, surfactants nthuav qhia cov khoom sib txawv. They have a range of physicochemical characteristics, including dispersion, wetting or anti-sticking, emulsification or demulsification, foaming or defoaming, solubilization, washing, preservation, and antistatic effects. Cov cuab yeej siv cov hauv paus tseem ceeb yog qhov tseem ceeb rau cov ntawv nkig Nyem thiab ua. Txheeb cais qhia tau hais tias dhau 3,000 hom surfactants yog siv nyob rau hauv cov txheej txheem kev lag luam textile, uas yog qhov tseem ceeb, tig, zas, luam ntawv, thiab xov. Lawv lub luag haujlwm yog txhawm rau txhim kho qhov zoo ntawm textiles, txhim kho kev ua tau zoo ntawm yarns, thiab lub sijhawm luv luv; Yog li, surfactants pab txhawb rau kev lag luam textile.

 

1. Kev siv cov surfactants hauv kev lag luam textile

 

1.1 Ntxhua txheej txheem

Hauv kev ntxuav cov txheej txheem ntawm textile ua, nws yog qhov tseem ceeb kom tsis txhob tsuas yog ntxuav cov txiaj ntsig tab sis kuj yog mos mos ntawm cov ntaub thiab cov teeb meem yog cov teeb meem tseem ceeb. Yog li ntawd, txoj kev txhim kho surfactants tshiab uas muab kev lom zem tu kom zoo thaum tswj kev muag khoom thiab xim ruaj khov ntawm cov ntaub tau dhau los ua qhov tseem ceeb ntawm cov kev tshawb fawb hnub no. Nrog rau kev tiv thaiv kev tiv thaiv kev tiv thaiv ib puag ncig thiab kev siv hluav taws xob ib puag ncig, thiab yooj yim-chim, thiab yooj yim-tsis muaj teeb meem hauv kev lag luam nrawm.

1.2 Down ua

Surfactants pab ntau lub luag haujlwm, ua haujlwm rau ob qho tib si uas tsis tuaj yeem ua cov xim tso ua thiab ua cov neeg sawv cev theem hauv dyeing. Tam sim no, anionic surfactants feem ntau yog siv raws li dispersants, suav nrog Naphthalene sulfonate-formensehyde condensates thiab lig sulfonates. Nonultic Surfactants li Nonylophenol Ethoj cog yog feem ntau sib xyaw nrog lwm hom surfactants. Cationic thiab zwitterionic surfactants muaj qee qhov kev txwv hauv daim ntawv thov. Raws li tshiab ntxig thev naus laus zis, xws li microwave dyeing, ua npuas dej, thiab cov neeg ua kua dej khov kho, cov kev cai ua kom cov neeg sawv cev ntawm qib thiab disperstants tau dhau los.

1.3 cov neeg sawv cev

Ua ntej dyeing thiab xov, textiles feem ntau yauv ua ntu zus xws li scouring thiab tshuaj dawb, uas tuaj yeem ua rau muaj kev xav txhais tes. Txhawm rau ua kom ruaj khov, du, thiab muag tes, softening cov neeg-feem ntau ntawm cov uas yog surfactants-yog qhov tsim nyog. Anionic Soften cov neeg sawv cev tau siv sijhawm ntev tab sis ntsib kev sib tw vim yog tus nqi tsis zoo ntawm cov dej, ua rau muaj cov teebmeem tsis zoo. Qee hom yog tsim nyog siv rau hauv cov roj textile li Softening cov khoom siv, suav nrog cov roj sulfosuccinate thiab sulfated roj.

Cov kev softic soften cov cev ua haujlwm ua tau zoo ib yam li anionic sawv daws tsis ua rau zas xim tsis zoo; Lawv tuaj yeem siv nrog anionic lossis cationic softening cov neeg sawv cev tab sis muaj kev ua tsis tau zoo fiber adsorption thiab qis zog. Lawv feem ntau yog siv rau hauv kev tshaj tawm ntawm corulosic fibers thiab li softening thiab smoothing Cheebtsam hauv cov khoom siv roj hluav taws xob fiber ntau. Cov chav kawm xws li pentaeryritol fatty acid esters thiab sorbitan fatty acid esters yog qhov tseem ceeb, ua kom muaj kev sib txhuam ntawm kev sib txhuam rau cov xov xwm cellulosic thiab hluavtaws.

Cationic Surfactants ua rau muaj zog khi nrog ntau yam fibers, yog cua sov-resistant thiab tivthaiv ntxuav, muab kev nplua nuj thiab muag muag zoo siab. Lawv kuj yaum cov tshuaj tivthaiv cov tshuaj tiv thaiv thiab cov tshuaj tua kab mob zoo, ua rau lawv muaj cov neeg sawv cev tseem ceeb thiab siv tau ntau dua thiab dav siv cov khoom siv. Feem ntau ntawm cov cationic surfactants yog nitrogen-muaj cov tebchaw, feem ntau suav nrog quarternary ammonium ntsev. Ntawm lawv, Dihydroxyethyl Quandary Ammonium cov sib xyaw ua ke Sawv cev rau lawv qhov kev ua tau zoo, ua tiav cov txiaj ntsig zoo nkauj, txawm hais tias lawv muaj ntau thiab pose biodegradation nyuaj. Ib tiam tshiab ntawm cov khoom lag luam ntsuab feem ntau muaj cov txheej txheem surfactants nrog eside cov pab pawg uas yooj yim hydroxyrable los ntawm fatty acids, yog li muaj kev cuam tshuam ib puag ncig.

1.4 Antistatic tus neeg sawv cev

Txhawm rau tshem tawm lossis tiv thaiv hluav taws xob zoo li qub tsim hluav taws xob thaum muaj ntau yam ntaub ntawv thiab hauv cov ntaub ua tiav cov txheej txheem, cov tshuaj tiv thaiv cov neeg sawv cev xav tau. Lawv lub luag haujlwm tseem ceeb yog los cuam tshuam cov dej noo thiab ionic cov khoom siv rau cov khoom lag luam muaj kuab thiab kev coj ua kom tsis txhob muaj hluav taws xob thiab tiv thaiv hluav taws xob. Ntawm surfactants, anionic antistatic cov neeg sawv cev yog cov muaj ntau haiv neeg. Cov roj sulfated, fatty acids, thiab cov pa roj carbon ntau tuaj yeem muab cov tshuaj tua kab mob, ua kom zoo nkauj, thiab emulsifying khoom. Alkyl sulfates, tshwj xeeb yog ammonium ntsev thiab ethanolamine ntsev, muaj ntau dua antistatic ua tau zoo.

Ntxiv mus, alkylphenol ethoxylate sulfates sawv tawm ntawm cov ensionic ittistatic cov neeg sawv cev rau lawv kev ua haujlwm zoo dua. Feem ntau, cationic surfactants yog tsis tsuas yog cov tshuaj tiv thaiv cov tshuaj tiv thaiv zoo tab sis kuj tau txais cov khoom zoo nkauj thiab cov khoom nplaum fiber ntau. Lawv cov teeb meem suav nrog cov tsos uas muaj xim zas tsho, txo cov nyom, muaj kev sib cav sib ceg, thiab tawv nqaij ua rau lawv cov khoom lag luam feem ntau yog cov roj. Cationic Surfactants siv raws li cov tshuaj tiv thaiv cov neeg sawv cev feem ntau muaj Quanary Ammonium sib txuas thiab cov rog acids thiab fatty acid amides. Zwitterionic surfactants, xws li betaines, muab cov tshuaj tiv thaiv zoo thiab lub roj me, emulsifying, thiab dispersing cov khoom.

Nonicic surfactants nthuav qhia cov dej noo muaj zog thiab haum rau cov av noo tsawg ntawm cov fibers. Lawv feem ntau tsis cuam tshuam rau zas kev ua tau zoo thiab tuaj yeem hloov kho cov roj ntau li cov khoom siv hluav taws xob tsawg, uas muaj cov roj ntsha tsis zoo thiab cov roj ntsha ethod polyethylene glycolol esters.

1.5 Penetrants thiab cov chaw ntub dej

Penetrants thiab cov chaw ntub dej yog cov tshuaj ntxiv uas txhawb nqa kev nyab xeeb ntawm fiber ntau lossis cov dej ua ke nrog cov kua rau hauv cov qauv fiber ntau. Surfactants uas tso cai rau cov kua kom nkag mus los yog nrawm nrawm ntawm cov kua rau hauv cov khib nyiab ntxeem tau yog cov neeg nkag siab. Kev nkag mus yog kev sib tw ntawm kev ntub dej txaus ua ntej thawj zaug. Kev ntub dej yog hais txog qib uas ib qho kua kis tau dhau ntawm qhov chaw saum npoo thaum muaj kev sib cuag. Yog li ntawd, cov neeg sawv cev rau cov neeg sawv cev thiab cov chaw ntub dej tau siv tsis tau ua ntej kev tsim kho, npau taws, thiab tshuaj dawb, thiab tshuaj dawb tab sis kuj tseem dav hauv kev luam ntawv thiab cov txheej txheem ua tiav.

Cov yam ntxwv yuav tsum tau ntawm cov neeg ua haujlwm thiab cov neeg sawv cev ntub dej suav nrog: 1) tsis kam: 1) tsis zoo rau dej nyuaj thiab alkali; 2) muaj peev xwm nkag mus rau lub peev xwm luv luv; 3) Kev txhim kho tseem ceeb ntawm Capillarity ntawm kho cov ntaub. Cationic Surfactants yog tsis tsim nyog li ntub dej sawv cev vim tias lawv tuaj yeem tshaj tawm mus rau cov fibers thiab tabkaum ntub ntub. Zwitterionic surfactants muaj qee qhov kev txwv hauv daim ntawv thov. Li no, surfactants siv raws li cov neeg nkag siab thiab cov neeg sawv cev ntub dej feem ntau muaj anionic thiab cov tsis muaj anionic thiab cov semfactic thiab tsis muaj qhov tseeb. Tsis tas li ntawd, surfactants nyob rau hauv textile kev lag luam kuj tseem siv tau ua kom ua kom cov neeg sawv cev, cov neeg sawv cev ua npuas, kho cov neeg sawv cev, thiab cov tshuaj tua dej.

Alkyl polyglucoside (apg) yog bio-surfactant synthesized los ntawm ntuj muaj roj cawv thiab cov piam thaj los ntawm cov khoom siv tau yooj yim dua. Nws yog hom tshiab ntawm kev tsis yog surfactant nrog kev ua tau zoo, ua ke cov khoom ntawm ob qho kev cai tsis muaj tseeb thiab anionic surfactants. Nws tau raug lees paub thoob ntiaj teb raws li cov nyiam "ntsuab" ua haujlwm surfactant, tus cwj pwm los ntawm kev ua haujlwm siab, kev nyab xeeb kev nyab xeeb, thiab solubility.
