Mbali & Ubwino

1. Zilibe APEO kapena phosphorous, ndi zina zotero. Zimagwirizana ndi zofunikira zachitetezo cha chilengedwe.
2. Zotsatira zabwino kwambiri za kutulutsa, kuthirira, kutsuka ndi kubalalitsa kwa dothi lamafuta ndi zonyansa.
3. Amapereka nsalu zabwino kwambiri za capillary, zoyera kwambiri, mthunzi wowala komanso mphamvu zolimba.
4. Oyenera scouring, bleaching ndi whitening osamba limodzi.Kwambiri imatithandiza chikhalidwe ndondomeko.Amachepetsa deoxygenization, neutralization ndi njira yotsuka madzi.Amapulumutsa mphamvu ndi kuchepetsa kuipitsa.

Kupaka thonje ndi zina za cellulosic fibizi

Kupukuta ndi njira yofunika kwambiri yonyowa yomwe imagwiritsidwa ntchito pazinthu za nsalu musanadye kapena kusindikiza.Nthawi zambiri ndi njira yoyeretsera momwe zinthu zakunja kapena zonyansa zimachotsedwa.Kupukuta, pamene kuyeretsa α-cellulose, kumapereka khalidwe la hydrophilic ndi permeability yofunikira pazotsatira (kuyeretsa, mercerizing, dyeing kapena kusindikiza).Kupukuta bwino ndiye maziko a kumaliza bwino.Kachitidwe ka scouring amayesedwa ndi kusintha kwa wettability wa zinthu zokokoloka.

Makamaka, kuchapa kumachitidwa kuti achotse mafuta osafunika, mafuta, phula, zonyansa zosungunuka ndi dothi lililonse kapena lolimba lomwe limamatira ku ulusi, zomwe zikanalepheretsa utoto, kusindikiza ndi kumaliza.Njirayi imakhala ndi chithandizo ndi sopo kapena chotsukira ndi kapena popanda kuwonjezera kwa alkali.Kutengera mtundu wa ulusi, alkali ikhoza kukhala yofooka (monga phulusa la soda) kapena lamphamvu (caustic soda).

Sopo akagwiritsidwa ntchito, madzi ofewa abwino amafunikira.Iyoni yachitsulo (Fe³⁺ndi Ca²⁺) kupezeka m'madzi olimba ndipo pectin ya thonje imatha kupanga sopo wosasungunuka.Vutoli ndi lovuta kwambiri pamene scouring ikuchitika mosalekeza kuphatikizapo kusamba kwa padding komwe chiŵerengero cha mowa chimakhala chochepa kwambiri kusiyana ndi ndondomeko ya batch;mwachitsanzo, Ethylenediaminetetraacetic acid (EDTA), Nitrilotriacetic acid (NTA), etc., angagwiritsidwe ntchito poletsa scum ndi kupanga mafilimu.Chotsukira chopangira chapamwamba kwambiri chimapereka chiwongolero chabwino ndikunyowetsa, kuyeretsa, emulsifying, kubalalika ndi kuchita thovu, motero kumapereka luso loyeretsa bwino.Zotsukira za anionic, zosakhala ndi ionic kapena zophatikizira, zotsukira zosungunulira ndi sopo zimagwiritsidwa ntchito kwambiri pakukwapula.Pofuna kufulumizitsa ndondomekoyi, nthawi zina amagwiritsidwa ntchito pofuna kunyowetsa pamodzi ndi zosungunulira zotentha kwambiri (cyclohexanol, methylcyclohexanol, etc.)Ntchito ya zosungunulira nthawi zambiri ndikusungunula mafuta osasungunuka ndi sera.

Omanga amawonjezeredwa kumadzi owiritsa a kier kuti awonjezere ntchito ya sopo kapena zotsukira.Izi nthawi zambiri zimakhala mchere monga borates, silicates, phosphates, sodium chloride kapena sodium sulphate.Sodium metasilicate (Na₂SiO₃, 5h ndi₂O) amathanso kukhala ngati chotsukira komanso chotchingira.Ntchito ya buffer ndikuyendetsa sopo kuchokera kumadzi kupita ku nsalu / mawonekedwe amadzi ndikuwonjezera kuchuluka kwa sopo pansalu.

Pakuwira thonje ndi caustic soda, mpweya wotsekeka ukhoza kuyambitsa makutidwe ndi okosijeni wa cellulose.Izi zitha kupewedwa powonjezerapo chochepetsera pang'ono monga sodium bisulphite kapena hydrosulphite mu mowa wokolopa.

Njira zopangira zovala zamitundu yosiyanasiyana zimasiyana mosiyanasiyana.Pakati pa ulusi wachilengedwe, thonje yaiwisi imapezeka mu mawonekedwe oyera kwambiri.Kuchuluka kwa zonyansa zomwe ziyenera kuchotsedwa ndizochepera 10% ya kulemera kwake.Komabe, kuwira kwanthawi yayitali ndikofunikira chifukwa thonje lili ndi phula lolemera kwambiri, lomwe ndi lovuta kuchotsa.Mapuloteniwa amagonanso mkatikati mwa fiber (lumen) yomwe imakhala yosafikirika ndi mankhwala omwe amagwiritsidwa ntchito popukuta.Mwamwayi mapadi sakhudzidwa ndi chithandizo chanthawi yayitali ndi caustic yankho mpaka ndende ya 2% pakalibe mpweya.Chifukwa chake, ndizotheka kutembenuza zonyansa zonse pakukwapula, kupatula zinthu zachilengedwe, kukhala zosungunuka, zomwe zimatha kutsukidwa ndi madzi.

Kupaka ulusi wa cellulosic kupatula thonje ndikosavuta.Ulusi wa bast ngati jute ndi fl ax sungathe kuwomedwa mosiyanasiyana chifukwa cha mwayi wochotsa zinthu zingapo zopanda ulusi ndikuwonongeka kwa zinthuzo.Izi nthawi zambiri zimatsukidwa pogwiritsa ntchito sopo kapena detergent pamodzi ndi phulusa la soda.Jute amagwiritsidwa ntchito pafupipafupi popanda kuyeretsedwanso, koma nkhwangwa ndi ramie nthawi zambiri zimapetedwa ndipo nthawi zambiri zimawulitsidwa.Jute wopaka utoto amawunikiridwa kale koma kuchuluka kwa lignin kumatsalira, zomwe zimapangitsa kuti zisachedwe bwino.

Popeza zonyansa zachilengedwe monga sera ya thonje, zinthu za pectic ndi mapuloteni zimagwirizanitsidwa makamaka mkati mwa khoma loyambirira, ndondomeko yopukuta ikufuna kuchotsa khoma ili.
