Lub luag haujlwm ntawm tus neeg sawv cev ntub dej yog ua kom cov khoom khov yooj yim ntub los ntawm dej. Los ntawm kev txo nws qhov kev nruj ntawm qhov chaw lossis kev nruj ntawm qhov chaw, dej tuaj yeem nthuav dav ntawm qhov chaw ntawm cov khoom khov lossis nkag mus rau hauv qhov chaw, yog li ua rau cov khoom khov ntub.

Tus neeg sawv cev ntub dej yog ib qho surfactant uas tuaj yeem ua rau cov khoom khov yooj yim ntub los ntawm dej los ntawm kev txo nws lub zog ntawm qhov chaw. Cov neeg sawv cev ntub dej yog surfactants, uas yog tsim los ntawm cov pab pawg hydrophilic thiab lipophilic. Thaum nyob rau hauv kev sib cuag nrog qhov chaw khov, pab pawg lipophilic txuas rau qhov chaw khov, thiab pab pawg hydrophilic nthuav dav mus rau hauv cov kua, yog li cov kua tsim ib theem txuas ntxiv mus rau ntawm qhov chaw khov, uas yog lub hauv paus ntsiab lus ntawm kev ntub dej.

Tus neeg sawv cev ntub dej, tseem hu ua tus nkag mus, tuaj yeem ua rau cov khoom khov kho yooj yim ntub los ntawm dej. Nws yog vim qhov txo qis ntawm qhov nro ntawm qhov chaw lossis qhov nro ntawm qhov chaw, yog li dej tuaj yeem nthuav dav ntawm qhov chaw ntawm cov khoom khov kho lossis nkag mus rau hauv lawv qhov chaw kom ntub lawv. Qhov degree ntub yog ntsuas los ntawm lub kaum sab xis ntub (lossis lub kaum sab xis sib cuag). Lub kaum sab xis ntub me dua, qhov zoo dua cov kua ntub qhov chaw khov kho. Cov kua thiab cov khoom khov kho sib txawv kuj sib txawv. Siv rau hauv textile, luam ntawv thiab zas xim, ua ntawv, tanning thiab lwm yam lag luam. Nws kuj tseem siv rau hauv kev npaj cov latex, ua tus neeg sawv cev tua kab thiab mercerizing, thiab qee zaum ua tus neeg sawv cev emulsifier, dispersant lossis stabilizer. Tus neeg sawv cev ntub siv hauv kev lag luam khoom siv photosensitive xav tau kev huv siab thiab kev tsim khoom tshwj xeeb.
