PROCESSING METHOD FOR TAPER OF NEEDLE-SHAPED BRISTLE ENHANCED THROUGHPUT
摘要
The present invention relates to a method of tapering a toothbrush bristle which increases production efficiency. The method includes the steps of cutting bundles of toothbrush bristles; and non-directionally immersing the entire cut bundles of toothbrush bristles into a chemical solution to taper both sides of the toothbrush bristles. According to the present invention, the production efficiency of a needle-shaped bristle is increased approximately three times, and the loss of raw materials is greatly decreased because several processes are not performed.
