Thaum koj muab cov khaub ncaws rau hauv lub tshuab ziab khaub ncaws kom qhuav, ntxiv cov khaub ncaws softener thiab cov khaub ncaws softener txoj cai ntawm kev txiav txim yog tib yam, tab sis cov khaub ncaws softener hauv softener yog tso tawm rau saum huab cua.Qhov tsawg heev ntawm cov khaub ncaws softener thiab cov tshuaj tiv thaiv zoo li qub ntxiv thaum ziab diffuses hauv huab cua sov thiab nkag mus rau hauv cov ntaub ntub dej fibers, yog li ua haujlwm.
Fabric softening agents yog surfactants, chemicals uas ua los txo qhov nro ntawm ob yam khoom sib txawv.Soaps thiab detergents kuj yog surfactants uas ua los txo cov roj-nto nro, ua kom yooj yim ntxuav cov av oily.
Surfactant molecules muaj ob yam: ib feem yog soluble nyob rau hauv roj tab sis insoluble nyob rau hauv dej, thaum lub lwm yam yog opposite.Qhov feem pua ntawm cov rog rog uas muaj nyob rau hauv cov ntaub softener feem ntau yog siab, thiab feem ntau muaj qee qhov ntev fatty chains nrog cov dej-soluble pawg, qee qhov yog anionic (tus nqi tsis zoo) los yog cationic (tus nqi zoo), thiab qee qhov tsis raug them (hluav taws xob nruab nrab).
Cov fatty Cheebtsam ntawm cov ntaub softener yuav tsim ib tug nyias oily zaj duab xis nyob rau saum npoo ntawm fibers nyob rau hauv kev sib cuag nrog ib leeg, thiaj li yuav txo tau cov kev sib txhuam ntawm cov fibers zawv zawg rau ib leeg, yog li ntawd lub txav nto yuav yooj yim dua swb hla. lawv.Cationic lossis non-ionic dej-soluble pawg yog siv los tshem tawm cov hluav taws xob zoo li qub uas tsim los ntawm ntau cov anions txuas nrog rau cov khaub ncaws.
Cov cationic softeners yog siab-raws li dimethyl ammonium chloride, thiab lwm yam, thaum cov nonionic softeners yog polyethylene glycol stearate, thiab lwm yam.
