Abstract: A PVA sponge with vegetal starch and bamboo charcoal includes at least one Polyester fiber substrate having through pores inside thereof, and a PVA foaming material having vegetal starch and bamboo charcoal therein. The substrate is covered by the PVA foaming material and will have acetalization by formaldehyde. The substrate is placed into a container with a predetermined shape and the PVA foaming material mixed with formaldehyde and hydrochloric is poured into the container. The colloid PVA and formaldehyde will have acetalization so that the PVA foaming material will cover among the structure of the substrate. A heating-up forming process is carried out when the PVA foaming material is full of the container. The added hydrochloric is an accelerator to accelerate the reaction.

Abstract: A vibrating and twinkling device which may mounted upon an appearance member for stationery or textile products includes a circuit element, light emitting diodes, power supplies, a vibrating switch, and a transparent encapsulation body. The circuit element includes a circuit board and a circuit control element. The light emitting diodes are mounted on and electrically connected to the circuit board. The power supplies electrically connect with the circuit element for supplying power. The vibrating switch electrically connects to the circuit board. The transparent encapsulation body covers the circuit element, the light emitting diodes, the power supplies, and the vibrating switch. Thereby, the vibrating and twinkling device is waterproof. When the vibrating switch is vibrated, the light emitting diodes can be driven to glow and twinkle, which offers splendid effects when the stationery or textile product is used.
