Njira yonse kuyambira ulusi mpaka kuluka ndi kudaya!

Kuyimba: Yatsani thonje pamwamba pa nsaluyo kuti nsaluyo ikhale yoyera komanso yokongola, komanso kupewa kupenta kapena kusindikiza kosiyana chifukwa cha kupezeka kwa fluff panthawi yopaka utoto kapena kusindikiza.

Desizing: chotsani kukula kwa imvi nsalu ndi anawonjezera lubricant, softeners, thickeners, zotetezera, etc., amene n'kopindulitsa kwa wotsatira otentha ndi blekning processing.

Kusungunula: chotsani zonyansa zachilengedwe munsalu zotuwa monga zinthu za waxy, pectin, zinthu za nayitrogeni ndi mafuta ena, ndi zina zotero, kuti nsaluyo ikhale ndi madzi enaake, omwe ndi abwino kuti azitha kutulutsa ndi kufalitsa utoto panthawi yosindikiza. ndi njira yopaka utoto.

Bleaching: Chotsani utoto wachilengedwe pa ulusi ndi zonyansa zachilengedwe monga matumba a mbewu za thonje, perekani nsalu kuyera koyenera, ndikuwongolera kuwunikira ndi utoto wa utoto.

Mercerization: Kupyolera mu chithandizo chokhazikika cha caustic soda, kukula kokhazikika, gloss yokhazikika komanso kuwongolera kwamphamvu kwa utoto kumapezedwa, ndipo mawonekedwe akuthupi ndi amakina monga mphamvu, kutalika ndi kukhazikika zimasinthidwa.

2. Mitundu ya mitundu yomwe imagwiritsidwa ntchito kwambiri

Utoto wachindunji: Utoto wachindunji umatanthawuza utoto womwe ukhoza kuwotchedwa ndi kuwiritsidwa mumtanda wosalowerera kapena wofooka wamchere kuti udaye mwachindunji ulusi wa thonje. Imakhala yolunjika kwambiri ku ulusi wa cellulose, ndipo sikofunikira kugwiritsa ntchito utoto wokhudzana ndi njira zama mankhwala kupangira ulusi ndi zinthu zina.

Utoto wosungunuka: Ndi utoto wosungunuka m'madzi wokhala ndi magulu omwe amagwira ntchito mu molekyulu, womwe umatha kulumikizana ndi magulu a hydroxyl pa ma cellulose pansi pamikhalidwe yofooka ya alkaline. Kuthamanga kwa masana kwa utoto wokhazikika kumakhala bwinoko. Pambuyo kutsuka ndi kuyandama kwathunthu, kufulumira kwa sopo ndi kupukuta kumathamanga kwambiri.

Utoto wa Acid: Ndi mtundu wa utoto wosungunuka m'madzi wokhala ndi magulu a acid mu kapangidwe kake, omwe amapakidwa utoto wa acidic. Mitundu yambiri ya asidi imakhala ndi sodium sulfonate, yosungunuka m'madzi, yowala mumtundu komanso wathunthu mumitundu yosiyanasiyana. Amagwiritsidwa ntchito kwambiri popaka ubweya, silika ndi nayiloni, ndi zina zotero. Zilibe mphamvu zopaka utoto ku ulusi wa cellulose.

Utoto wa Vat: Utoto wa Vat susungunuka m'madzi. Popaka utoto, amayenera kuchepetsedwa ndikusungunuka mu njira yochepetsera zamchere kuti apange mchere wa leuco-chromatic sodium kuti udaye ulusi. Pambuyo pa oxidation, amabwerera kunyanja zosasungunuka za utoto ndikuzikonza pa ulusi. Nthawi zambiri amatha kutsuka, kufulumira kwa kuwala kumakhala kokwera.

Utoto wobalalitsa: Utoto wobalalitsa uli ndi mamolekyu ang'onoang'ono ndipo palibe magulu osungunuka m'madzi. Iwo amamwazikana mofanana mu njira yothetsera utoto mothandizidwa ndi dispersants popaka utoto. Thonje la poliyesitala lopakidwa utoto wobalalika limatha kupakidwa utoto wa poliyesitala, ulusi wa acetate ndi ulusi wa poliyesitala wa amine, ndipo umakhala utoto wapadera wa poliyesitala.
