1. Substrate
Ntoo pulp fiber: Feem ntau suav rau 70% -90% (cov ntaub ntawv qhov chaw: INDA tus qauv qhia), tshwj xeeb yog kho kom luv fiber ntau ntev thiab txhim kho dej dispersibility.
Viscose fiber ntau: Qee cov khoom ntxiv 10% -30% regenerated cellulose fiber los txhim kho kev yooj yim thiab pab txhawb biodegradability.
Cov txheej txheem tsis-woven npuag: Ua haujlwm hydroentangling lossis huab cua- tso lub vev xaib thev naus laus zis kom tsis txhob siv cov nplaum yas.
2. Cov khoom siv ntxiv
Humidifiers: propylene glycol los yog glycerin (kwv yees li 3% -5%), tswj cov av noo tab sis yuav tsum tau tswj cov proportions los tiv thaiv cov nplaum.
Surfactants: Cog - muab cov khoom xyaw xws li cocoyl glucoside (feem ntau yog<1%), ensuring detergency and low irritation.
Cov tshuaj tua kab mob: Phenoxyethanol lossis potassium sorbate (tsawg dua lossis sib npaug li 0.5%), ua tau raws li cov qauv tshuaj pleev ib ce - qib kev nyab xeeb.
3. Ib puag ncig tus phooj ywg additives
Biodegradable polymers: Polylactic acid (PLA) lossis polyhydroxyalkanoate (PHA) yog siv los txhim kho lub zog ntawm cov ntaub ntub dej. Tus nqi decomposition yuav tsum siab dua lossis sib npaug li 90% hauv 28 hnub (saib rau OECD 301B tus qauv xeem).
