Ukusetyenziswa kwe-Agent ye-Dispersed Die Leveling kwi-Dayi kunye nePolyester

Iidayi ezisasazwayo zisetyenziselwa ukudaya iintsinga ze-hydrophobic ezifana ne-polyester, i-spandex, inayiloni, kunye ne-acetate fibers. Ngokuqhubela phambili okuqhubekayo kwetekhnoloji yokudaya ifayibha, iintlobo ezahlukeneyo zeearhente zokulinganisa zenze inkqubela phambili ebalulekileyo.

1. I-arhente yomgangatho wokudaya lobushushu obuphezulu

Xa usebenzisa iidayi ezisasaziweyo kwiqondo eliphezulu kunye noxinzelelo oluphezulu lokudaya, ukudaya okungalinganiyo kudla ngokubangelwa zizinto ezifana nokungahambi kakuhle, ukufana, kunye nokudluliselwa kwedayi, kunye nokulawulwa ngokungafanelekanga kwezinga lokufudumeza. Ngokukodwa kwimicu ye-polyester efanelekileyo, ubuninzi bomgca buphantsi kakhulu, indawo ephezulu iyanda, kwaye isantya sokudaya sedayi siyakhawuleza. Ukongeza, ukwakheka kwelaphu eliqinileyo kwenza kube nzima ukungena kwedayi, nto leyo ekhokelela kukungalingani okubonakalayo kokudaya kunemicu yepolyester eqhelekileyo. Ukusetyenziswa kwe-agent ehambisa umgangatho ophezulu wokushisa ngexesha lokudaya kunokuphucula umphumo wokulinganisa amalaphu kunye nokuphucula umgangatho wemveliso.

Ngokubanzi, i-non-ionic surfactants ingasetyenziswa njengee-agent zokulinganisa iidayi ezisasazekileyo ezingekho-ionic, ezinokuthi zenze iibhondi ze-hydrophobic kwaye zicothise isantya sokudaya ukufikelela kwinqanaba. Phakathi kwee-non-ionic dispersing leveling agents, i-polyoxyethylene ester surfactants inomgangatho wokusebenza ongcono kune-polyoxyethylene ether surfactants (izakhiwo ze-ester zine-affinity enkulu ye-polyester kune-ether structures), kunye nee-surfactants ezineringi ze-benzene zisebenza ngcono kune-fatty surfactants.

Nangona kunjalo, ama-non-ionic surfactants athambekele ekuphelelweni kwamanzi ngexesha lobushushu obuphezulu bokudaywa kwepolyester, kwaye ukubopha phakathi kwamatyathanga e-ethylene oxide kunye ne-hydroxyl, i-amino, kunye namanye amaqela asebenzayo kwiimolekyuli zedayi yi-adsorption ekhululekile ngokwasemzimbeni, iswele amandla okunxibelelana kwe-ion kunye nokuhlakazeka okubi kunye ne-solubilization. Xa usebenzisa i-low cloud point non-ionic surfactants, udibaniso lwedayi lunokwenzeka kakhulu. Ngenxa yomgangatho oqinileyo wentlawulo engalunganga eyenziwe yi-adsorption ye-anionic surfactants kumphezulu wamasuntswana edayi, kukho ukunyanzeliswa kombane okunamandla phakathi kwamasuntswana edayi ukwenza imo ezinzileyo esasazekileyo, enesakhono esinamandla sokusasaza kwi-agglomerates yeedayi ezisasaziweyo, ngaloo ndlela kuncitshiswe ukubumbana kwazo kunye nokugcina ukudaya kwisisombululo kwidayi. Oku kunokusombulula ingxaki yeendawo zedayi ezibangelwa yindawo ephantsi yefu ye-nonionic surfactants.

I-agent ye-high-performance high-temperature leveling agent iqulunqwe ngokusebenzisa i-synergistic and synergistic effects of non-ionic kunye ne-anionic surfactants, apho izakhiwo ezahlukeneyo zecandelo ngalinye zineempembelelo ezahlukeneyo. Zininzi iimveliso zearhente zomgangatho wobushushu obuphezulu (ezinye zazo zikwabandakanya abathwali abathile) ezenziwe nge-anionic/nonionic surfactants. Izakhiwo ezahlukeneyo zecandelo ngalinye zinemisebenzi eyahlukeneyo, ngokukodwa ihlulwe: 1) isakhiwo se-ethoxy sinokubamba iidayi ezihlakaziweyo, ukwandisa iindawo zedayi, kunye nokulibazisa ukudaya ngexesha lenkqubo yokudaya; 2) Xa ubushushu bokudaya bufikelela kwixabiso elibalulekileyo, iikhompawundi ezinuka kamnandi zinokubangela ngokukhawuleza iplastiki kunye nokudumba kwefiber zepolyester, ukunciphisa ubushushu beglasi yokutshintsha kwepolyester nge-20-25 ℃, kwandisa kakhulu iipores ngaphakathi kwimicu, kunye nokuvumela idayi ukuba idaywe ngokukhawuleza kwaye igxininise idayi imicu. Kwangaxeshanye, banokusebenza njengezinto zokunyibilikisa iidayi ukuze ziqhubeke zihlanjululwa kwaye zikhuphe kwimicu, okukhokelela ekufudukeni okubalulekileyo (ukudlulisa ukudaya) ukufikelela kwisiphumo esifanayo sokudaya.

Ezinye zeemveliso ezintsonkothileyo ze-surfactants zineempawu eziphezulu zogwebu, ezinokubangela iingxaki ngokulula koomatshini bokudaya ngokukhawuleza kunye nokudaya okuncinci kweebhafu. Ke ngoko, ii-agent zomgangatho ophantsi wogwebu ziyafuneka. Isisombululo kukongeza i-defoamers, ngakumbi i-organosilicon defoamers, esebenza kakhulu kwiqondo lokushisa eliphezulu; Iimveliso ezinogwebu eziphantsi zifumaneka ngokucopolymerizing ethylene oxide kunye nepropylene oxide.
