Abstract: PURPOSE: A manufacturing method of cellulose particle is provided to provide cellulose particle having nano size, to mull with a thermoplastic resin, to provide cellulose particles, and to recycle wood raw material. CONSTITUTION: A manufacturing method of cellulose particle comprises a step of pulverizing a mixture containing cellulose and surfactant by a pulverizer which consists of an upper part and a lower part of pillar shape, and has the weight ration of the upper part and the lower part of 3:1-8:1. The cellulose is manufactured by purifying wood based raw material. The surfactant is one or more alkoxysilane selected from a group consisting of tetramethoxysilane, tetraethoxysilane, tetrapropoxysilane, and tetrabutoxysilane.

Abstract: PURPOSE: A producing method of low molecular weight lignin using a wood composite raw material is provided to prevent the environmental contamination, and to produce a coating film having antibacterial property. CONSTITUTION: A producing method of low molecular weight lignin using a wood composite raw material comprises the following steps: refining high molecule weight lignin from the wood composite raw material; decomposing the high molecule weight lignin to obtain the low molecular weight lignin; and extracting the obtained low molecular weight lignin. The average molecular weight of the high molecule weight lignin is greater than 5,000. The average molecular weight of the low molecule weight lignin is 100-500.
