Abstract: A method for producing a biopolymeric material includes milling a non-edible vegetable fiber into a fiber grain; mixing the fiber grain with a solvent to form a slurry; purifying the fiber grain of the slurry to form a purified fiber; esterifying the purified fiber to form an esterified fiber; drying the esterified fiber to form a modified fiber; and mixing the modified fiber with a plastic material to form the biopolymeric material.

Abstract: A method for producing a bio-based polymeric shoe component includes: preparing a blend from a composition including 5˜50 weight parts of a modified starch, 50˜95 weight parts of an ethylene vinyl acetate copolymer, 5˜30 weight parts of a filler, 1˜50 weight parts of a polyolefin, 2.0˜8.0 weight parts of a foaming agent, 0.5˜3.0 weight parts of a foaming aid, 0.5˜2.0 weight parts of a lubricant, and 0.4˜1.2 weight parts of a crosslinking agent, the modified starch being obtained by hydrolyzing and esterifying a predetermined amount of a raw starch to form a hydrolyzed and esterified starch, followed by drying the hydrolyzed and esterified starch; processing the blend into a foamable product; and forming the foamable product into the shoe component.

Abstract: A lamp arm structure which is an elongated chain structure composed of multiple coupling blocks which are serially connected. Each coupling block has an annular flange at the middle to divide the coupling block into two ends. One end of the coupling block is formed with a cup-like socket section, while the other end is formed with an engaging section having several domed protuberances on the surface. The engaging section of one coupling block can be inserted into the socket section of another coupling block to serially connect the coupling blocks into the chain structure. Each coupling block can be freely universally rotated about the engaging section so that the lamp arm can be multidirectionally bent to adjust the angle of a bulb holder.

Abstract: The present invention relates to an easy assembling and disassembling lamp whose lampshade and lamp arm are connected by screws to make it detachable and assembling. The present invention is characterized in that: the lampshade and the lamp arm are jointed with screws in place of traditional rivets, allowing for detachment; the one-piece long lamp arm are replaced with several short shafts assembled together to reduce its volume. In this way, the lamp can be detached and assembled, making warehousing and transportation more easily as well as reducing cost of transportation and saving space.
