Kukula kwa Reactive Dyeing Technology

M'zaka zaposachedwa, njira yatsopano yodayira utoto wokhazikika yakula mwachangu.Njira zomwe zimagwira ntchito popaka utoto zikuphatikizapo: utoto wothira utoto wopaka utoto komanso utoto waufupi wopaka nthunzi, utoto wokhazikika wothira utoto wocheperako, utoto wocheperako komanso utoto wozizira wa batch, ndi utoto wosalowerera ndale, utoto wokhazikika wopanda mchere wambiri komanso wopanda mchere, gwiritsani ntchito utoto "wolowa m'malo wamchere" wopaka utoto wopanda mchere wambiri, utoto wokhazikika wa alkali komanso utoto wosalowerera.

1.Reactive dye pad dyeing ndi chonyowa lalifupi nthunzi dyeing.Kupaka utoto ndi njira imodzi yofunika kwambiri yodaya utoto wokhazikika.Komabe, nsaluyo ikathiridwa ndi yankho la utoto wa pad, kuyanika kwapakatikati kumafunika kuti pakhale kutentha kotsatira, kapena kuonjeza liwiro la kukonza pakuphika ndi kukonza.Ndi kuchepetsa utoto hydrolysis, ndi kupeza mkulu fixation mlingo ndi mtundu fastness.Kuyanika kwapakatikati kudzabweretsa mavuto ambiri: kugwiritsa ntchito mphamvu, kutentha kwakukulu kumagwiritsidwa ntchito poyanika nsalu zonyowa kuti zisungunuke madzi;utoto umakonda kusamuka panthawi yowuma, zomwe zimapangitsa kusiyana kwa mitundu ndi kuchepa kwa mtundu, komanso kutulutsanso utoto kumakhala koyipa;Kuyanika pambuyo pa kuviika njira yothetsera utoto sikungowonjezera njira yopangira ndipo kumakhala kovuta kuyendetsa, komanso pamene nsalu youma imatenthedwa, utoto ndi mankhwala ayenera kuyamwa madzi kuti asungunukenso.Nsalu youma idzatulutsa kutentha ikatenga chinyezi, zomwe zimapangitsa kutentha kwambiri, zomwe zimawononga utoto ndi kukonza.Chifukwa chake, kusuta ndi cholinga chanthawi yayitali chomwe anthu amatsata.Ndizovuta kwambiri kupangira nsalu zotayidwa ndi nthunzi.Choyamba, nsalu yonyowa imatenthedwa mwachindunji.Chifukwa chakuti chinyezi chimatenga kutentha ndikutuluka, kutentha kwa nsalu kumachepetsedwa, zomwe zimatalikitsa nthawi yowotcha ndi kukonza;chachiwiri, nsaluyo imakhala ndi chinyezi chochuluka (kawirikawiri mlingo wamadzimadzi pambuyo pa padding ndi 60% mpaka 70%), mkati mwa nthunzi ndi kutentha, utoto wokhazikika pa nsaluyo udzakhala ndi hydrolysis yambiri, yomwe imachepetsa kukhazikika. mlingo ndi mtundu fastness.Chinyezi pa nsalu chimakhala ndi mayiko ambiri, omwe amatha kugawidwa m'magulu awiri: madzi omwe amamwa ulusi komanso madzi aulere pansalu.Madzi omangidwa ndi mankhwala omwe amamwa madzi (makamaka omangiriridwa ku fiber molecular chain kudzera mu ma hydrogen bond) amatchedwanso madzi osazizira (kuzizira kwake kumakhala kotsika kwambiri kuposa 0 ° C).Gawo ili la madzi ndilochepa, ndipo mwayi wochita ndi utoto ndi wochepa, chifukwa sungathe kuyenda momasuka.Mbali yochuluka ya madzi otengedwa ndi fiber pores.Fiber pores ndi woonda kwambiri.Mbali imeneyi ya madzi si yophweka kuyenda momasuka, choncho imatchedwanso madzi omangika.Kachitidwe kake ndi utoto ndi wotsika.Ngakhale kuti gawo la madzi aulere kunja kwa fiber liri mu inter-fiber capillary ndipo silosavuta kuyenda chifukwa cha capillary effect, zambiri zimatha kuyenda momasuka.Madzi m'mayiko awiriwa kunja kwa ulusi ndi osavuta kuyankha ndi utoto.Utoto ukakhala wokwera, umafunika kuti utotowo usapitirire kuchuluka kwa hydrolysis, ndipo kukhazikika kwachangu kumachitika mukafika kutentha kokwanira.Pachifukwa ichi, mankhwala a alkali oyenera kugwiritsidwa ntchito ayenera kukhala ofooka, kapena alkalinity sayenera kukhala yamphamvu pamene chinyezi cha nsalu ndi chapamwamba (kuphatikizapo alkali wosakaniza wa soda kapena phulusa la soda ndi zina za alkali), ngati alkali wochepa. kapena kusalowerera ndale kumachitidwa Zotsatira zake zidzakhala bwino.Kafukufuku wapeza kuti kugwiritsa ntchito osalowerera ndale kukonza mtundu kumakhala ndi zotsatira zabwino pa 120 ~ 130 ℃ kapena 180 ℃.

2.Short reactive dye dip dyeing process imafupikitsa njira yopangira utoto, imathandizira kupanga bwino, imapulumutsa mphamvu, imasunga madzi, komanso imachepetsa kutulutsa kwa zimbudzi.Kupaka utoto kwakanthawi kochepa konyowa ndi njira yayifupi yodaya utoto wa pad.Njira yaufupi yopaka utoto wopaka utoto ndiyonso cholinga cha kafukufuku m'zaka zaposachedwa, kukonza zida, kufupikitsa nthawi yopaka utoto, ndipo koposa zonse, kuwongolera koyenera kwa njira yopaka utoto, komanso kuwongolera makompyuta okha kumatha kufupikitsa utoto, kukonza ndi kutsuka. nthawi.M'zaka zaposachedwapa, makampani ambiri opanga utoto apanga njira zopangira utoto mwachangu pofuna kutsatsa malonda awo.Maziko a njira yopaka utoto mwachangu ndikusankha utoto moyenerera molingana ndi mawonekedwe awo, ndikufupikitsa nthawi yonse yopaka utoto potengera kuwonetsetsa bwino komanso kuberekana.Tengani metering yoyendetsedwa ndi kuwonjezera mosalekeza, zomwe zingafupikitse nthawi.Sungani kwambiri utoto, alkalis ndi mchere, komanso kuchepetsa kutaya kwa zimbudzi.Njira zina zimawongoleranso kutsuka pambuyo popaka utoto kuti muteteze madzi komanso kuchepetsa zimbudzi.Ena opanga utoto kapena zida apanganso mapulogalamu osiyanasiyana okhazikika odaya.

Ndife ogulitsa Reactive Dyeing.Ngati muli ndi chidwi ndi katundu wathu, chonde omasuka kulankhula nafe.
