Play particles within Attachment newsprint

摘要

An object of the present invention is to both is recovered and used the main components in the pulp fibers and fillers and pigments is of waste paper, provision of resources circulation type of playback particles in Attachment newsprint. A is a deinking floss filler is discharged from the process of waste paper as a main material, the main raw material dehydration process, drying process, sintering process and the surface of the obtained reproduction particle aggregates by passing through a grinding step There are internally added as a silica-coated regeneration particle aggregates the filler coated with silica, wherein the pulp is made ​​from 50 to 100 wt% waste paper pulp, basis weight conforming to JIS P 8124 is a 37~48g / m ² There, the paper ash was measured according to JIS P 8251 in the paper is contained 4 to 15 weight%, JIS P 8143 Clark was measured according to stiffness is 30~55cm ^3/100 reproduced intraparticle added newspaper paper.
