Kev tshem tawm cov silicone mos rau ntawm knitted tiav ntaub
Nyob rau hauv xyoo tas los, silicone softeners tau tsim kho sai thiab tau siv dav hauv cov mos mos ntawm qib high-knitted fabrics. Silicone softener tuaj yeem muab cov ntaub npuag knitted mos, du, puv thiab elastic tes, nrog rau kev tiv thaiv wrinkle, abrasion tsis kam, ntxuav thiab xaws, thiab zoo heev txhim kho tus nqi ntxiv ntawm cov khoom, uas tau nyiam los ntawm cov neeg siv khoom.
Cov ntaub ntawv silicone ua kom ruaj khov yog tshuaj lom neeg thiab yog tus tsim cov dej-insoluble macromolecular qauv. Nws muaj zog muaj peev xwm ua kom nto tau zoo, thiab qee cov pab pawg reactive tsim cov ntawv cog lus sib txuas nrog cov tshuaj tiv thaiv los yog tus kheej-hla kev sib txuas, ua rau lub tsev polymerly ywj siab qauv ntawm cov fiber ntau. Yog li ntawd, nws nyuaj heev kom tshem tawm cov silicone mos ntawm cov ntaub qhwv knitted tiav los ntawm cov qauv txheej txheem. Txawm li cas los xij, tus nqi ntawm dyeing thiab kho cov knitted ntaub yog siab dua. Yog tias cov ntaub nqus dej tsis tshem tawm, cov ntaub thaiv lossis kho cov ntaub yuav tsis muaj xim txhua lub sijhawm. Yog tias qhov kev tshem tawm tsis huv, nws yuav ua rau cov xim pom tseeb, tsuas yog Cov ntaub so ntswg silicone ntawm daim ntaub ua haujlwm raug tshem tawm rau kev tawm tsam thiab kho. Tom qab rov qab sim thiab loj-teev ntau lawm kev txhawb nqa thiab daim ntawv thov, ib txoj kev rau kev ua haujlwm zoo tshem tawm cov silicone muag ntawm knitted tiav ntaub tau pom.
1 txoj kev tshem tawm txoj kev kuaj
1.1 Cov khoom siv kuaj thiab khoom siv
Ntaub: polyester ntos ntaub, polyester / paj rwb sib xyaw xaws ntaub, paj rwb xaws ntaub
Reagents: Silica DM-1741 (Shunde Demei), silicone softener SA (South Hiav Txwv Saite), caustic sis dej qab zib (qib muaj), dej qab zib tshauv (qib muaj), Alcoa AD (ciba), 27.5% hydrogen peroxide (muaj qib)
Khoom Siv: Tshaj Dav Hlau Dyeing Tshuab (Hong Kong Lixin)
1.2 Ntsuas cov txiaj ntsig thiab kev sib tham
Kev ntsuas phom silicone ua kom tshem tawm tau ua tiav ntawm cov ntaub ntawv-ntaub plaub-polyester, paj rwb-knitted ntaub thiab polyester / paj rwb plooj ntaub knitted nrog cov qauv sib txawv. Cov txiaj ntsig tau tshwm sim hauv Rooj Lus 1, Daim Duab 2 thiab Rooj 3, ntsig txog txhua yam.
Cov txiaj ntsig kev ntsuas hauv lub rooj yog 1-5, uas sib raug rau cov txiaj ntsig tshem tawm ntawm cov roj silicone ua kom zoo ntawm qhov kev txiav txim tsis zoo, tsis zoo, nruab nrab, zoo thiab zoo heev. Thaum cov nyhuv tshem tawm tau mus txog qib 4, kev zas xim thiab kev kho ntawm daim ntaub yuav tsis tshwm xim.
2 cov txiaj ntsig thiab kev sib tham
(1) Cov roj carbon fiber ntau ntawm cov xov paj polyester-tsis muaj ntau pawg polar xws li hydroxyl pawg, thiab alkali-muaj zog caustic dej qab zib ua ke nrog cov kab mob silicon-tshem tawm tus neeg tuaj yeem tuaj yeem tshem cov silicone mos rau ntawm daim ntaub nto mus rau theem ntawm 4, thiab daim ntaub yog counter-dyed thiab xa rov qab. Yuav tsis muaj xim paj.
Cov txiaj ntsig ntawm kev tshem tawm cov silicone mos los ntawm Alcosan AD (acrylic quaternary ammonium ntsev) thiab silica gel DM-1741: hluav taws xob polyester knitted ntaub qib 5, polyester / paj rwb sib xyaw knitted ntaub ntawm qib 4 lossis siab dua. Qhov laj thawj yog vim li cas Alcoa AD tuaj yeem yaj lub aminosilicone emulsified thiab tom qab ntawd koom tes nrog kev ua haujlwm ntawm kev tshem tawm cov silicon ntsuj plig, thiab cov nyhuv zoo dua.
(2) Cov phuam xaws paj rwb kom muaj ntau ntawm cov pawg hydroxyl rau ntawm cov roj pawg. Thawj plaub txoj hauv kev hauv rooj 2 tsis txaus siab. Tsuas yog 27.5% hydrogen peroxide siv, ua ke nrog Alcoa thiab caustic soda, uas rhuav tshem kev tsim ntawm aminosilicon thiab fiber. Cov ntawv cog lus sib txuas lossis kev sib txuas tus kheej tuaj yeem ua tiav cov nyhuv ntawm tag nrho emulsifying thiab yaj lub silicone muag muag.
(3) Polyester / paj rwb sib xyaw knitted ntaub muaj ob qho tib si polyester thiab paj rwb fiber ntau cov qauv. Raws li qhov kev sib piv uas muaj txhij txhua, cov txiaj ntsig tshem tawm ntawm Alcosan AD ua ke nrog SiGeling DM-1741 yog qhov zoo tshaj plaws.
(4) Nws tau raug txheeb xyuas los ntawm kev sim ua kom pom tias kev tshem tawm tsis yog tsuas yog tsim nyog rau kev tshem tawm cov roj silicone ua kom zoo li SA, tab sis kuj rau kev tshem tawm feem ntau ntawm cov muag muag silicone.
Cov txheej txheem saum toj no yog thov rau kev tsim tag nrho ntawm polyester, paj rwb thiab polyester / paj rwb blended knitted ntaub, uas muaj txiaj ntsig zoo daws teeb meem ntawm lub teeb, nruab nrab-xim tsis sib haum thiab kho cov xim ntawm knitted ntaub tom qab muag xov ntawm silicone softener. Qhov teeb meem ntawm kev muaj peev xwm siab ntawm kev xeb ntawm cov pob zeb tsis txau ntawm cov pob zeb tau raug pom zoo thiab thov los ntawm knitting tshuaj dawb thiab zas xim.
