Abstract
A bio-derived wearable film includes an acid-hydrolyzed palm stem pith, a starch, a cellulose, a synthetic polymer, a plant hydrogel, glycerin, and a dye, and a method of producing the bio-derived wearable film. The bio-wearable film has a water absorption of 0.00 to 0.16% measured according to ASTM D570; a carbonate content of 100 to 200 ppm; and shows no cracks when tested according to ASTM D5419.
Claims17
A method of producing a bio-derived wearable film, the method comprising
- washing palm stem pith with a sodium hypochlorite solution;
- then
- blending the palm stem pith and water to form a raw plant mixture;
- heating the raw plant mixture to form a cooked plant mixture;
- acid treating the cooked plant mixture with an aqueous acid at 30 to 60° C. to form a treated plant mixture;
- mixing the treated plant mixture with a starch, a cellulose, a synthetic polymer, a plant hydrogel, glycerin, and a dye to form an uncured mixture;
- adjusting a pH of the uncured mixture to a pH of 6.5 to 8.5;
- heating the uncured mixture to 125 to 175° C. to form a cured mixture;
- and
- drying the cured mixture at 60 to 100° C. to form the bio-derived wearable film.
A biodegradable glove made from a non-woven bio-derived wearable film, wherein the non-woven bio-derived wearable film comprises:
- an acid-hydrolyzed palm stem pith;
- a starch;
- a cellulose containing nanocellulose having a mean particle size of 10 to 35 nm;
- a synthetic polymer;
- a plant hydrogel;
- glycerin;
- and
- a dye,
- wherein the non-woven bio-derived wearable film has a tensile modulus of 0.25 to 2.0 GPa and a tensile strength of 50 to 100 MPa/kg·m3.
