Abstract
本発明は、木材を粉砕し且つ乾燥した後に所定の大きさ以下に分級して選び抜き、選び抜かれた木粉を漂白設備に漂白剤とともに送り込んで所定時間攪拌しながら漂白を行い、漂白された木粉を研磨し、分級し且つ選び抜くことにより製造された漂白木粉5〜20重量%を天然パルプ80〜95重量%と混合して製紙を行うことを特徴とする。
【選択図】図2
Description
本発明は、製紙に際して、木粉を再生パルプと混合して用いる方式から逸脱して、木粉を漂白した後に天然パルプと混合して製紙を行うことにより、天然パルプの使用量を低減する一方で、バルク性を向上させて脱水性を増大させて省エネルギーを図っている。
