1.Cationic Softener
Chifukwa ulusi wambiri pawokha umakhala ndi vuto loyipa, zofewa zopangidwa ndi ma cationic surfactants zimatha kutsatiridwa bwino.fiberpamwamba, zomwe zimachepetsa kupsinjika kwa ulusi komanso kukangana pakati pa magetsi osasunthika ndi ulusi ndipo zimapangitsa kuti ulusi utambasule m'malo momamatirana, kuti pakhale kufewetsa.Zofewa za cationic ndizofunikira kwambiri zofewa.
Zofewa za cationic zilinso ndi zabwino izi:
Iwo ali ndi mphamvu yolumikizana kwambiri ndi fiber.Amatha kutsuka komanso osamva kutentha kwambiri.
Mlingo wocheperako ukhoza kukwaniritsa kufewetsa kwambiri.Ndiwofewetsa bwino kwambiri.
Amatha kupereka nsalu zabwino zofewa.
Iwo akhoza kusintha kuvala kukana ndi kung'amba mphamvu ya nsalu.
(1) Chofewetsa mchere wa amine
Zofewetsa mchere wa amine ndi cationic mu sing'anga ya acidic.Iwo ali wamphamvu adsorption zotsatira pa CHIKWANGWANI.Katundu wa cationic wa zofewa zotere ndizofooka.Kotero iwo amatchedwa ofooka cationic softeners.Pofuna kulimbikitsa kuyanjana ndi ulusi ndikuwongolera kukhazikika, magulu ochitapo kanthu amathanso kuwonjezeredwa mu mamolekyu.
Zofewa za Monoalkyl ndi dialkyl cationic zomwe zimakhala ndi magulu a amide ndi mtundu watsopano wa zofewa.Magulu amafuta a amide ndi olimba kwambiri ndipo amatha kupangitsa nsalu kukhala zofewa komanso zonenepa komanso zolimba m'manja komanso kulimba mtima.
(2) Ofewetsa mchere wa Quaternary ammonium
Quaternary ammonium salt softeners ndi cationic mu acidic ndi alkaline medium.Amagwiritsidwa ntchito kwambiri, omwe ali ndi magulu osiyanasiyana.
2.Amphoteric Softener
Zofewa za amphoteric zimakhala ndi mgwirizano wamphamvu kwambiri wa ulusi wopangira popanda kuipa kwa chikasu, kusintha mtundu wa utoto kapena kuletsa fulorosenti.whitening wothandizira.Zitha kugwiritsidwa ntchito mkati mwamitundu yambiri ya pH.Mitundu yomwe imagwiritsidwa ntchito kwambiri yamtunduwu wa zofewa makamaka ndi amphoteric betaine yokhala ndi unyolo wautali wa hydrophobic ndi mawonekedwe a amphoteric imidazoline.
3. Nonionic Softener
Zofewa za Nonionic sizimayamwa bwino ndi ulusi poyerekeza ndi zofewa za ayoni.Ali ndi mphamvu zochepa pazitsulo zopangira, zomwe zimagwira ntchito yosalala.Amagwiritsidwa ntchito makamaka pomaliza ulusi wa cellulose, makamaka oyenera kufewetsa kutsirizitsa kwa nsalu za bleaching ndi nsalu zamtundu wowala.Ndipo ali ndi kuyanjana kwabwino ndi othandizira ena komanso kukhazikika kwa electrolyte popanda chilema mu nsalu zachikasu.Zitha kugwiritsidwa ntchito ngati zofewa zosakhalitsa zomaliza.Zopangira zazikuluzikulu ndi condensation ya stearic acid yokhala ndi ethylene oxide, pentaerythritol fatty acid ester, sorbitol fatty acid ester ndi surfactant yokhala ndi polyether structure.
4.Anionic Softener
Zofewa za anionic zimakhala ndi kunyowa kwabwino komanso kukhazikika kwa kutentha.Atha kugwiritsidwa ntchito limodzi ndi fluorescent whitening agent pakusamba komweko.Atha kugwiritsidwa ntchito ngati zofewa pansalu zoyera, zomwe sizingapangitse kusinthika kwa nsalu.Zofewa zambiri za anionic zimagwiritsidwa ntchito pomaliza thonje,ulusi wa viscosendi zinthu za silika zenizeni.Chifukwa ulusi umakhala ndi vuto loyipa m'madzi, zofewa za anionic sizimakopeka mosavuta.Chifukwa chake kufewetsa kwa zofewa za anionic ndizovuta kwambiri kuposa zofewa za cationic.Mitundu ina ndi yoyenera kugwiritsidwa ntchito ngati zigawo zofewa mumafuta opota.
