Ben. /. Sulfonated. wothandizira), kusungunuka kwake kwakukulu ndi kusungunuka kwa utoto, nthawi yomweyo kuchotsa asidi sing'anga, Ndipo phala loyambirira mu nthunzi yopangidwa ndi kuchepetsa mpweya, kuteteza utoto wokhazikika posindikiza, nthunzi posindikiza phala loyambirira kuchepetsa kapena kuchepetsa kuwonongeka kwa gasi mu bokosi la nthunzi, ndizomwe zimateteza utoto mu nthunzi, mu nthunzi zimatha kupewa kuchepetsa kuwonongeka kwa zinthu zomwe zimayamba chifukwa cha kutha kwa utoto kapena mdima. Mwachitsanzo, 5-10 g / lKutsutsa Samawonjezeredwa ku phala lamtundu, zomwe zingalepheretse ulusi wa nsalu kuti usachepetse kutentha kwambiri, ndikulepheretsa kuchepetsa mpweya mumtundu woyera pamtundu wa utoto. Komabe, kuchuluka kwa mitundu yosinthika yamitundu yosiyanasiyana sikufanana, monga utoto wokhazikika womwe umakhudzidwa mosavuta ndi kuchepetsedwa, kuchuluka kwake kuyenera kuonjezedwa mpaka 15 g / l, monga ofiira owala K-2G, wofiirira K-3R, ndi X yogwira buluu. -Br, D-GR, MR ndi mitundu ina ya oxidation reactive reactive dyes yokhala ndi bromoamino monga kholo sayenera kuwonjezeredwa ikagwiritsidwa ntchito yokha, kuti zisawonongeke. Kuphatikiza apo, pakusindikiza utoto wa corduroy reactive, pamafunika kukhala ndi phala lomveka bwino. Nthawi zambiri, zamkati za sodium alginate zimasankhidwa, ndipo thickener FS-86 imagwiritsidwa ntchito posindikiza utoto wokhazikika, womwe uli ndi ubwino wa utoto wowala, wowoneka bwino, wochapitsidwa, womveka bwino komanso wopanda gel ku utoto wakuda. Amagwiritsidwa ntchito pokonzekera slurry. The chilinganizo wamba ndi: kukonzekera woyera phala choyamba, zinthu ndi 25 sodium alginate phala 50%, 1%, soda 3%, urea 5%, madzi 37%, oyambitsa ndi dissolves pambuyo kuwonjezera fS-86 za 4%, kuyambitsa ndi kukhuthala. Kenako, kuchuluka koyenera kwa utoto ndi pafupifupi 20% yamadzi mutatha kusungunuka, onjezerani 80% ya phala loyera, yambitsani nthawi yomweyo kapena gwiritsani ntchito. Nthawi zambiri, Resist S akadali mpweya wabwino // mankhwala/othandizira omwe amagwiritsidwa ntchito posindikiza zamkati. Pakusindikiza nsalu, imagwiritsidwa ntchito makamaka ngati anti-dyeing agent, yomwe ingalepheretse utoto wa utoto ndi kupanga mapangidwe pamapangidwe a nsalu ndi utoto. Kuphatikiza apo, monga utoto wapakati, utoto wina ukhoza kupangidwa. Mu kusindikiza nsalu, kuchuluka kwa ntchito makamaka motere.
1. Monga chowonjezera chotsutsana ndi zoyera cha utoto wa VAT
Anti-staining mchere S ndi mankhwala odana ndi staining agent. Kusindikiza kwa utoto wa VAT wotsutsa - kudaya, nsalu yoyera idayamba kusindikizidwa zamkati zoyera, kenako ndikugudubuza utoto wa shilin. Kuwonjezera kuwonjezera chlorine kwa woyera slurry. Chemical. Zinc (acid stain inhibitor), titaniyamu woyera. Ufa, nthawi zina umagwirizananso ndi kuchuluka kwa mchere wosungirako mchere S monga wothandizira kusungirako, mfundo yake ndikugwiritsa ntchito ndi mpweya / mphamvu, imatha kuthetsa inshuwalansi ya shilin dyeing powder kuchepetsa mphamvu, kupanga thupi la leuco dye mochedwa kwambiri pa fiber fixation ndi mpweya / kutsogolo kulowa m'nyanja yoyambirira ya utoto, osati ndi ulusi wopaka utoto, kutanthauza kuti chivundikiro chamowa cha shilin chopaka utoto wamalo oyera pansalu, Chifukwa cha anti-white slurry ndi odana ndi utoto mchere S mpweya ///. Kukhalapo kwa wothandizira, wochepetsera muzitsulo za utoto wa shilin, kuti ateteze utoto wa shilin kuti ulowe mu ulusi wa thonje, potero kumapangitsa kuti thupi likhale loyera.
2. Kwa mchere wamkuwa, ntchito, utoto wa naftol ndi mtundu wina wamtundu wapansi wosindikizira woteteza mtundu.
Nsalu yamtundu wapansi yosindikizira, monga duwa, wofiira, wofiira, tsiku lofiira, khofi, mphukira zobiriwira ndi mitundu yosiyanasiyana ya zipatso, musanasindikize, ngati sichoncho kupyolera muyeso yoyenera ya mpweya /. Mankhwala / wothandizira pretreatment ndi kusindikiza kwa mzere, nthawi zambiri kumatulutsa mpumulo. Chodabwitsa ichi chimayamba chifukwa chakuti pakupaka utoto, zamkati zosindikizira sizimachotsedwa kwathunthu ndi scraper, kotero kuti palibe chitsanzo pamwamba pa nsalu yamtundu wapansi, komanso imatha kusindikizidwa pachojambula choyera. . Ufa, chifukwa pang'ono woyera kusema. Ufa pansi mtundu wa kuwonongeka padziko ndi mapangidwe mpumulo. Ngati pali mpeni wokoka kapena kukoka slurry, zochitika zotsitsimula zimakhala zovuta kwambiri, zomwe zimawononga kukongola kwa nsalu pamwamba pake ndikupanga chilema chowonekera.
Kuchokera kusanthula mankhwala, pamwamba pa nthaka mtundu kuonongeka ndi kuchepetsa wothandizila, akhoza kukhala mu mtundu pansi pa chisanadze kuviika adagulung'undisa kuchuluka kwa okosijeni/mankhwala./ wothandizira, kukana osati kukanda woyera. Ufa. Koma pali kuchuluka kwa okosijeni, ngati kupitirira mphamvu ya mpweya / mankhwala /. Mthandizi, ndizofunika kwambiri. Ufawo udzaphwanya mtundu wa nthaka. Choncho, mtundu uwu wa okosijeni amangofunika kupanga phindu linalake, koma safuna kusema zoyera zonse. Powder offset, kotero kuti kumene kusindikiza kumafunika, kukhoza kupangitsa kuti mtundu wa nthaka ukhale wowonongeka ndikuwonetsa chitsanzo. Anti-stain salt S ndi okosijeni / mankhwala omwe amagwiritsidwa ntchito nthawi zambiri. Pambuyo poyanika nsalu, sungani ndikugudubuza njira iyi ya 2 ~ 3 g/l, yomwe imakhala yosavuta kutulutsa mtundu ndi malo amtundu waukulu, wotsutsa-kudaya mchere S mlingo ukhoza kuwonjezeka kufika 5 ~ 6 g/l. Zouma ndi kusindikiza. Pambuyo kuviika, pali mpumulo pang'ono kapena kukoka mpeni kuti musindikize, kotero ndi yoyera. Ufa ukhoza kukhala REDOX ndi mchere wotsutsa-dye S popanda kuwononga mtundu wa nthaka. Koma ngati ipitirira mphamvu yake yoyenera, idzawonongabe mtundu wa nthaka.
3. Kukonza wothandizira nsalu
Pambuyo pa kusindikiza kwa thonje, ngati pali mpeni wokoka kapena chodabwitsa m'zidutswa zambiri, zolakwika zazikulu zidzayamba pambuyo pa chithandizo cha nthunzi. Kuti athetse vutoli, nsaluyo iyenera kubwezeretsedwa ku malo osindikizira kuti ikonzedwe mwamsanga musanayambe chithandizo cha nthunzi. Kukonza kungathe kutengera kuchuluka kwa mpumulo, kuchuluka koyenera kwa mchere wothira utoto S (kuchuluka kwa 0.1 ~ 0.2 g/l) kuwonjezeredwa m'madzi, popanda chosema ndi pamwamba kusindikiza pa silinda yamaluwa ya hemp, kenako mankhwala nthunzi, kuti odana ndi utoto mchere S ndi kusema woyera. Zotsatira za ufa zimakhala bwino.
4. Kuti musindikize utoto wokhazikika pambuyo poteteza mtundu wa nthunzi
Utoto wokhazikika umasindikizidwa mwachindunji pansalu ya thonje pambuyo pa nthunzi, kuchepetsa zinthu kapena kuchepetsa mpweya mu makina a nthunzi, komanso kutentha kwambiri kwa nthunzi kulimbikitsa hydrolysis ya fiber ndi zamkati mwa kuchepetsa, nthawi zambiri zimakhudza kuwala kwa mtundu wawo ndikupangitsa kuti mdima. Ngati zamkati zosindikizira zikuwonjezedwa ndi mpweya wofooka // mankhwala // wothandizira anti-dye mchere S, pamene nthunzi processing pambuyo kusindikiza, kuchepetsa mphamvu ya makina nthunzi kuthetsedwa, choncho chitetezo cha zotakasika utoto ayenera kukhala owala. mtundu. Kuchuluka kwa mchere wothira utoto S nthawi zambiri kumayendetsedwa pafupifupi 10 g/l. Pamene mtundu wotentha wotentha ndi mtundu wamba zikufanana kapena kusindikizidwa palimodzi, nthawi ya nthunzi iyenera kukhala yotalikirapo, yomwe imakhudza kwambiri mtundu wa utoto wamba wogwiritsa ntchito. Kuchuluka kwa mchere wotsutsa-kudaya S kuyenera kuwonjezeka kufika 15 g/l. Chisamaliro kwambiri chiyenera kulipidwa pakugwiritsa ntchito osaya ndende ya zotakasika utoto phala pa nsalu pansi kusindikiza, kusindikiza zamkati ayenera kuwonjezeredwa kuchuluka kokwanira odana ndi utoto mchere S, kuti athetse ndi mkulu kutentha nthunzi kulimbikitsa CHIKWANGWANI. ndi zamkati hydrolysis yobweretsedwa ndi reductive, kuteteza mtundu wilting.
5. Monga zotakasika utoto PAd utoto - nthunzi njira mtundu kuwala chitetezo wothandizira
Kukhalapo kwa kuchepetsa mpweya mu chipinda cha nthunzi kudzakhudzanso mtundu wa utoto wamba ndi thermoset reactive dyes pambuyo popaka utoto wa pad ndi nthunzi. Kupaka utoto wowala ndikofunikira kwambiri, mutha kuwonjezedwa munjira yopaka utoto kuti mupewe kudaya mchere S pafupifupi 10 ~ 20 g/l, kupewa kufota kwa mtundu.
6. Imagwiritsidwa ntchito ngati chida choteteza kuyera pansalu ya ulusi wopaka utoto wa VAT panthawi yakukolota
Nsalu zina za mizere ya utoto wa VAT monga ngati poplin wamizeremizere yopaka utoto nthawi zambiri amasenda pang'ono ndi kuthimbirira ndi nthaka yoyera akawiritsa alkali. Pofuna kuthana ndi vuto ili, mchere wothira utoto S ukhoza kuwonjezeredwa ku soda scouring solution pafupifupi 1.5 ~ 3 g/l. Mchere wa anti-dye S ndi okosijeni wofooka // mankhwala // wothandizira, amatha kuteteza utoto pakuchepetsa kuwira ndikulowa ndikuwononga nthaka yoyera. Izi ndichifukwa chakuti mbali yoyera ya nsalu, chifukwa cha chitetezo cha mchere, sichidzakhudzidwa ndi chiopsezo cha kulowetsedwa kwa mtundu ndi utoto.
