TIPS:
Silicone softeners
Silicones tau muab cais ua ib pawg ntawm tib neeg tsim cov polymers muab los ntawm silicon hlau hauv xyoo 1904. Lawv tau siv los tsim cov tshuaj textile softening txij li xyoo 1960.Thaum pib, tsis hloov pauv polydimethylsiloxanes tau siv.Nyob rau xyoo 1970s, kev qhia txog aminofunctional polydimethylsiloxanes tau qhib qhov tshiab ntawm textile softening.Lub sij hawm 'silicone' yog hais txog cov khoom siv polymer raws li lub hauv paus ntawm kev sib hloov ntawm silicon thiab oxygen (siloxane bonds).Qhov loj atomic radius ntawm silicon atom ua rau silicon-silicon ib daim ntawv cog lus tsawg zog, li no silanes (SinH2 n+1) tsis tshua ruaj khov dua alkenes.Txawm li cas los xij, silicon-oxygen bonds muaj zog ntau dua (kwv yees 22Kcal / mol) dua li carbon-oxygen bonds.Silicone kuj muab los ntawm nws cov qauv zoo li kitone (silico-ketone) zoo ib yam li acetone.Silicones tsis muaj ob daim ntawv cog lus hauv lawv cov pob txha thiab tsis yog oxocompounds.Feem ntau, kev kho silicone ntawm textiles muaj silicone polymer (tsuas yog polydimethylsiloxanes) emulsions tab sis tsis nrog cov silane monomers, uas yuav tso tawm cov tshuaj lom neeg (xws li hydrochloric acid) thaum kho.
Silicones nthuav tawm qee cov khoom tshwj xeeb xws li thermal oxidative stability, tsis tshua muaj kub flowability, tsis tshua muaj viscosity hloov tiv thaiv kub, siab compressibility, qis nto nro, hydrophobicity, zoo hluav taws xob thiab hluav taws kub txaus ntshai vim lawv cov inorganic-organic qauv thiab yooj ntawm silicone bonds. .Ib qho ntawm cov yam ntxwv tseem ceeb ntawm cov khoom siv silicone yog lawv cov txiaj ntsig ntawm qhov qis heev.Tsawg heev ntawm silicones yuav tsum tau ua kom tiav cov khoom xav tau, uas tuaj yeem txhim kho tus nqi ntawm kev ua haujlwm textile thiab ua kom muaj kev cuam tshuam ib puag ncig yam tsawg kawg nkaus.
Lub mechanism ntawm softening los ntawm kev kho mob silicone yog vim ib tug saj zawg zog zaj duab xis tsim.Qhov txo qis zog xav tau rau kev sib hloov daim ntawv cog lus ua rau cov pob txha siloxane hloov tau yooj yim dua.Lub deposition ntawm saj zawg zog zaj duab xis txo interfibre thiab interyarn kev sib txhuam.
Yog li silicone xov ntawm textile ua ib qho tshwj xeeb mos kov ua ke nrog lwm yam khoom xws li:
(1) Smoothness
(2) Greasy xav
(3) Lub cev zoo heev
(4) Txhim kho crease kuj
(5) Txhim kho lub zog tsim kua muag
(6) Txhim kho sewability
(7) Zoo antistatic thiab antipilling zog
Vim tias lawv cov qauv inorganic-organic thiab qhov yooj yim ntawm siloxane bonds, silicones muaj cov yam ntxwv hauv qab no:
(1) Thermal / oxidative stability
(2) Tsawg-kub flowability
(3) Tsawg hloov viscosity nrog kub
(4) Siab compressibility
(5) Tsawg nto nro (spreadability)
(6) Tsawg hluav taws kub txaus ntshai
Silicones muaj ntau daim ntawv thov nyob rau hauv textile ua, xws li fiber ntau lubricants nyob rau hauv spinning, high-speed xaws machinery, winding thiab slashing, raws li binders nyob rau hauv nonwoven manufacturing, antifoam nyob rau hauv dyeing, li softeners nyob rau hauv luam paste, xov thiab txheej.
