Kugwiritsa Ntchito Dispersed Dye Leveling Agent mu Kudaya ndi Polyester

Utoto wa Disperse umagwiritsidwa ntchito kwambiri popaka utoto wa hydrophobic monga poliyesitala, spandex, nayiloni, ndi ulusi wa acetate. Ndi kupita patsogolo kosalekeza kwaukadaulo wopaka utoto wa fiber, mitundu yosiyanasiyana ya ma leveling agents yapita patsogolo kwambiri.

1. Wosanjikiza wopaka utoto wotentha kwambiri

Mukamagwiritsa ntchito utoto womwazikana popaka utoto wotentha kwambiri komanso wothamanga kwambiri, utoto wosagwirizana nthawi zambiri umayamba chifukwa cha zinthu monga kusabalalika, kufanana, kusamutsa utoto, komanso kuwongolera molakwika kutentha. Makamaka ulusi wabwino kwambiri wa poliyesitala, kachulukidwe ka mzerewu ndi wochepa kwambiri, pamwamba pake amawonjezeka, ndipo liwiro la utoto wa utoto limathamanga. Kuphatikiza apo, kapangidwe kansalu kolimba kamapangitsa kuti utoto ukhale wovuta kulowa, zomwe zimapangitsa kuti utoto ukhale wosiyana kwambiri kuposa ulusi wamba wa polyester. Kugwiritsa ntchito zida zoyatsira kutentha kwambiri pakupaka utoto kumatha kupititsa patsogolo luso la nsalu ndikuwonjezera mtundu wazinthu.

Nthawi zambiri, ma surfactants omwe si a ionic amatha kugwiritsidwa ntchito ngati zowongolera utoto wosabalalika wa ionic, womwe utha kupanga ma hydrophobic bond ndikuchepetsa kuthamanga kwa utoto kuti ufikire mulingo. Pakati pa zinthu zopanda ma ionic dispersing leveling agents, polyoxyethylene ester surfactants amachita bwino kuposa ma polyoxyethylene ether surfactants (mapangidwe a ester amalumikizana kwambiri ndi poliyesitala kuposa mapangidwe a ether), ndipo opaka mphete okhala ndi benzene amagwira bwino ntchito kuposa mafuta opangira mafuta.

Komabe, osakhala ionic surfactants sachedwa kuchepa madzi m'thupi pa mkulu-kutentha utoto utoto wa poliyesitala, ndi kumanga pakati ethylene okusayidi unyolo ndi hydroxyl, amino, ndi magulu ena zinchito mu mamolekyu utoto ndi thupi lotayirira adsorption, kusowa ion mgwirizano mphamvu ndi osauka dispersibility ndi solubilization. Mukamagwiritsa ntchito zida zotsika zamtambo zomwe sizikhala ndi ionic, kuphatikiza utoto ndikothekera kwambiri. Chifukwa champhamvu zoipa mlandu wosanjikiza wopangidwa ndi makonzedwe a anionic surfactants padziko utoto particles, pali amphamvu magetsi repulsion pakati particles utoto kupanga khola omwazika boma, amene ali ndi mphamvu dispersing mphamvu pa agglomerates omwazika utoto, potero kuchepetsa cohesiveness awo ndi kusunga dyestable mu dyestable. Izi zitha kuthana ndi vuto la mawanga opaka utoto omwe amayamba chifukwa cha mtambo wochepa wa ma nonionic surfactants.

Wothandizira kutentha kwapamwamba kwambiri amapangidwa pogwiritsa ntchito synergistic ndi synergistic zotsatira za non-ionic ndi anionic surfactants, kumene zosiyana za chigawo chilichonse zimakhala ndi zotsatira zosiyana. Pali zinthu zambiri zoyezera kutentha kwambiri (zina zomwe zimaphatikizanso zonyamula) zopangidwa ndi ma anionic / nonionic surfactants. Mapangidwe osiyanasiyana a chigawo chilichonse ali ndi ntchito zosiyanasiyana, makamaka zogawidwa mu: 1) kapangidwe ka ethoxy kumatha kutenga utoto wobalalika, kuwonjezera malo opaka utoto, ndikuchedwa kudaya panthawi yopaka utoto; 2) Pamene kutentha kwa utoto kufika pamtengo wovuta, mankhwala onunkhira amatha kuyambitsa pulasitiki ndi kutupa kwa ulusi wa polyester, kuchepetsa kutentha kwa magalasi a polyester ndi 20-25 ℃, kuonjezera kwambiri pores mkati mwa ulusi, ndi kulola utoto kuti udaye msanga komanso mozama ulusi. Nthawi yomweyo, amatha kukhala ngati zosungunulira za utoto kuti usungunuke ndikuchotsa ulusi, zomwe zimapangitsa kusamuka kwakukulu (kutumiza utoto) kuti akwaniritse utoto wofanana.

Zina mwa zinthu zovuta kwambiri zomwe zimapangidwa ndi ma surfactants zimakhala ndi thovu lalitali, zomwe zimatha kuyambitsa zovuta pamakina odaya mwachangu komanso utoto wocheperako. Chifukwa chake, othandizira otsika thovu amafunikira. Njira yothetsera vutoli ndi kuwonjezera ma defoamers, makamaka organosilicon defoamers, omwe amathandiza kwambiri pa kutentha kwakukulu; Mankhwala otsika thovu amapezedwa ndi copolymerizing ethylene oxide ndi propylene oxide.
