1.Iimpawu ze-amino silicone
I-amino silicone ineeparamitha ezine ezibalulekileyo: ixabiso le-ammonia, i-viscosity, i-reactivity, kunye nobukhulu be-particle. Ezi parameters ezine ngokusisiseko zibonisa umgangatho we-amino silicone kwaye zichaphazela kakhulu isitayile selaphu elicutshungulwayo. Okufana nokuziva kwesandla, ubumhlophe, umbala, kunye nokukhululeka kwe-emulsification ye-silicone.
① Ixabiso le-ammonia
I-amino silicone inika amalaphu aneempawu ezahlukeneyo ezifana nokuthamba, ukuguda, kunye nokugcwala, ikakhulu ngenxa yamaqela e-amino kwipolymer. Umxholo we-amino unokubonakaliswa ngexabiso le-ammonia, elibhekiselele kwiimililitha ze-hydrochloric acid kunye noxinzelelo olulinganayo olufunekayo ukuze unciphise i-1g ye-amino silicone. Ngoko ke, ixabiso le-ammonia lihambelana ngokuthe ngqo nepesenteji ye-mole ye-amino content kwioli ye-silicone. Ukuphakama komxholo we-amino, iphezulu ixabiso le-ammonia, kwaye ithambile kwaye ilula ukuthungwa kwelaphu eligqityiweyo. Oku kungenxa yokuba ukwanda kwamaqela asebenzayo e-amino kwandisa kakhulu ukuhambelana kwawo kwelaphu, ukwenza ilungiselelo eliqhelekileyo leemolekyuli kunye nokunika ilaphu ukuthungwa okuthambileyo kunye nokugudileyo.
Nangona kunjalo, i-hydrogen esebenzayo kwiqela le-amino ityekele kwi-oxidation ukwenza i-chromophores, ebangela ukuba ilaphu libe tyheli okanye libe tyheli kancinane. Kwimeko yeqela elifanayo le-amino, kuyacaca ukuba njengoko umxholo we-amino (okanye ixabiso le-ammonia) linyuka, amathuba okuba ne-oxidation yanda kwaye i-yellowing iba nzima. Ngokunyuka kwexabiso le-ammonia, i-polarity ye-amino silicone molecule iyanda, enika imfuneko efunekayo yokwenziwa kwe-emulsification yeoli ye-amino silicone kwaye ingenziwa kwi-emulsion encinci. Ukukhethwa kwe-emulsifier kunye nobukhulu kunye nokusabalalisa ubungakanani beengqungquthela kwi-emulsion nazo zihambelana nexabiso le-ammonia.
① Viscosity
I-Viscosity inxulumene nobunzima bemolekyuli kunye nokusabalalisa ubunzima be-molecular of polymers. Ngokubanzi, okukhona i-viscosity iphezulu, kokukhona ubunzima bemolekyuli be-amino silicone buba ngcono, kokukhona ipropathi yokwenza ifilimu ingcono kumphezulu welaphu, kokukhona imvakalelo ithambile, kwaye ngokukhona imtyibilizi igudiswa, kodwa imbi ngakumbi. ukukwazi ukungena. Ngokukodwa amalaphu ajijekileyo kunye namalaphu amahle e-denier, i-amino silicone kunzima ukungena ngaphakathi kwifiber yangaphakathi, echaphazela ukusebenza kwelaphu. Ukuphakama kakhulu kwe-viscosity kuya kwenza ukuzinza kwe-emulsion kube nzima okanye kunzima ukwenza i-emulsion encinci. Ngokuqhelekileyo, ukusebenza kwemveliso akunakulungelelaniswa kuphela nge-viscosity, kodwa ngokuqhelekileyo kulungelelaniswa ngexabiso le-ammonia kunye ne-viscosity. Ngokuqhelekileyo, ixabiso eliphantsi le-ammonia lifuna i-viscosity ephezulu ukulinganisa ukuthamba kwelaphu.
Ke ngoko, ukuziva kwesandla esigudileyo kufuna i-viscosity ephezulu ye-amino modified silicone. Nangona kunjalo, ngexesha lokucutshungulwa okuthambileyo kunye nokubhaka, enye i-amino silicone cross-link ukwenza ifilimu, ngaloo ndlela inyusa ubunzima bemolekyuli. Ke ngoko, ubunzima bokuqala bemolekyuli ye-amino silicone buhluke kubunzima bemolekyuli ye-amino silicone ekugqibeleni yenza ifilimu kwilaphu. Ngenxa yoko, ukugudiswa kwemveliso yokugqibela kunokuhluka kakhulu xa i-amino silicone efanayo icutshungulwa phantsi kweemeko ezahlukeneyo zenkqubo. Ngakolunye uhlangothi, i-viscosity ephantsi ye-amino silicone inokuphucula ukuthungwa kwamalaphu ngokudibanisa i-agent edibeneyo okanye ukulungelelanisa ubushushu bokubhaka. I-viscosity ephantsi ye-amino silicone yandisa ukufikeleleka, kwaye ngokusebenzisa i-agent edibanisayo kunye nokuphucula inkqubo, inzuzo ye-amino silicone ephezulu kunye nephantsi inokudibaniswa. Uluhlu lwe-viscosity ye-amino silicone eqhelekileyo iphakathi kwe-150 kunye ne-5000 centipoise.
Nangona kunjalo, kuyafaneleka ukuba uqaphele ukuba ukuhanjiswa kobunzima be-molecular of amino silicone kunokuba nefuthe elikhulu ekusebenzeni kwemveliso. Ubunzima bemolekyuli obuphantsi bungena kwifayibha, ngelixa ubunzima obuphezulu bemolekyuli busasazwa kumphezulu ongaphandle wefayibha, ukuze ngaphakathi nangaphandle kwefiber isongelwe yi-amino silicone, inika ilaphu imvakalelo ethambileyo negudileyo, kodwa Ingxaki inokuthi ukuzinza kwe-emulsion encinci kuya kuchaphazeleka ukuba umahluko wemolekyuli mkhulu kakhulu.
① Ukusebenza kwakhona
I-amino silicone esebenzayo inokuvelisa i-self cross-linking ngexesha lokugqiba, kwaye ukwandisa iqondo lokudibanisa kuya kwandisa ukuguda, ukuthamba, kunye nokugcwala kwelaphu, ngakumbi malunga nokuphuculwa kwe-elasticity. Ngokuqinisekileyo, xa usebenzisa i-agent-linking agents okanye ukunyuka kweemeko zokubhaka, i-amino silicone ngokubanzi inokunyusa i-degree-linking degree kwaye ngaloo ndlela iphucule i-rebound. I-silicone ye-amino ene-hydroxyl okanye i-methylamino ekupheleni, iphezulu ixabiso le-ammonia, ingcono idigri yayo yokudibanisa, kwaye ingcono i-elasticity yayo.
②Ubungakanani benxalenye ye-emulsion encinci kunye nentlawulo yombane ye-emulsion
Ubungakanani besuntswana le-amino silicone emulsion lincinci, ngokuqhelekileyo lingaphantsi kwe-0.15 μ, ngoko ke i-emulsion ikwimeko yokusasazeka kwe-thermodynamic. Ukugcinwa kokugcinwa kwayo, ukuzinza kobushushu kunye nokuzinza kwe-shear kugqwesileyo, kwaye ngokuqhelekileyo ayiphuli i-emulsion. Kwangaxeshanye, ubungakanani bamasuntswana amancinci anyusa ummandla womhlaba weengqungquthela, ukuphucula kakhulu ukunxibelelana okunokwenzeka phakathi kwe-amino silicone kunye nelaphu. Umthamo we-adsorption we-surface adsorption uyanda kwaye ukufana kuyaphucuka, kwaye ukunyanzeliswa kuphucula. Ngoko ke, kulula ukwenza ifilimu eqhubekayo, ephucula ukuthamba, ukugudisa, kunye nokugcwala kwengubo, ngakumbi kwiingubo ezintle ze-denier. Nangona kunjalo, ukuba ukusabalalisa ubungakanani be-particle ye-amino silicone ayilingani, ukuzinza kwe-emulsion kuya kuchaphazeleka kakhulu.
Intlawulo ye-amino silicone emulsion encinci ixhomekeke kwi-emulsifier. Ngokubanzi, ii-anionic fibers zilula ukubhengeza i-cationic amino silicone, ngaloo ndlela iphucula umphumo wonyango. I-adsorption ye-emulsion ye-anionic ayilula, kwaye umthamo we-adsorption kunye nokufana kwe-emulsion engeyona i-ionic ingcono kune-anionic emulsion. Ukuba umrhumo ongalunganga wefiber uncinci, impembelelo kwiipropati ezahlukeneyo zentlawulo ye-emulsion encinci iya kuncitshiswa kakhulu. Ke ngoko, iintsinga zekhemikhali ezinje ngepolyester zifunxa i-emulsion eyahlukeneyo encinci ngeentlawulo ezahlukeneyo kwaye ukufana kwazo kubhetele kunemicu yomqhaphu.
I-1.Impembelelo ye-amino silicone kunye neempawu ezahlukeneyo kwi-hand-feel of fabrics
① Ukuthamba
Nangona uphawu lwe-amino silicone luphuculwe kakhulu ngokubophelela kwamaqela asebenzayo e-amino kwiilaphu, kunye nokulungelelaniswa okucwangcisiweyo kwe-silicone ukunika amalaphu ukuva okuthambileyo kunye nokugudileyo. Nangona kunjalo, umphumo wangempela wokugqiba ubukhulu becala uxhomekeke kwindalo, ubuninzi, kunye nokusabalalisa amaqela asebenzayo e-amino kwi-amino silicone. Ngexesha elifanayo, i-formula ye-emulsion kunye ne-avareji ye-particle ye-emulsion ichaphazela ukuvakalelwa okuthambileyo. Ukuba ezi zinto zinempembelelo zingentla zinokufikelela kwibhalansi efanelekileyo, isitayile esithambileyo sokugqiba ilaphu siya kufikelela kweyona nto iphezulu, ebizwa ngokuba yi "super soft". Ixabiso le-ammonia le-amino silicone softeners ngokubanzi liphakathi kwe-0.3 kunye ne-0.6. Ukuphakama kwexabiso le-ammonia, ukusabalalisa ngokulinganayo amaqela asebenzayo e-amino kwi-silicone, kwaye i-laphu ethambileyo ivakalelwa. Nangona kunjalo, xa ixabiso le-ammonia lingaphezulu kwe-0.6, ukuthamba kwelaphu akunyuki kakhulu. Ukongezelela, i-particle encinci ye-emulsion, i-collective ngakumbi kwi-adhesion ye-emulsion kunye ne-soft feel.
② Ukuziva kwesandla esigudileyo
Ngenxa yokuba ukuxinana komphezulu wekhompawundi ye-silicone incinci kakhulu, i-amino silicone emulsion ilula kakhulu ukusasazeka kumphezulu wefiber, yenza imvakalelo elungileyo egudileyo. Ngokubanzi, incinci ixabiso le-ammonia kunye nobunzima bemolekyuli ye-amino silicone, ngcono ukuguda. Ukongeza, i-amino ephelisiwe i-silicone inokwenza ulungelelwaniso olucoceke kakhulu ngenxa yazo zonke iiathom zesilicon kumakhonkco ekhonkco adityaniswe kwiqela le-methyl, okukhokelela kwimvakalelo egqwesileyo yesandla.
