Title:
繊維状セルロース含有物、繊維状セルロース複合樹脂、及び繊維状セルロース含有物の製造方法
Document Type and Number:
Japanese Patent JP7213296
Kind Code:
B2
Abstract:
Provided are a fibrous cellulose-containing material having excellent dispersibility even when dried, a method for preparing the same, and a fibrous cellulose composite resin having excellent strength. The fibrous cellulose-containing material is for addition to resin, and contains fibrous cellulose having an average fiber width of 0.1 to 19 µm and having hydroxyl groups partially or fully substituted with carbamate groups, and interactive powder that is interactive with the fibrous cellulose. The fibrous cellulose composite resin contains the fibrous cellulose-containing material as fibrous cellulose. The method for preparing a fibrous cellulose-containing material includes defibrating fibrous cellulose having hydroxyl groups partially or fully substituted with carbamate groups to have an average fiber width of 0.1 to 19 µm, and mixing with interactive powder that is interactive with the fibrous cellulose to obtain a mixed liquid, and drying the mixed liquid.
