FIBER MATERIALS AND COMPOSITES Russian patent published in 2017 - IPC D06M13/00 D06M14/04 D06M15/05 D06M15/19 D06M15/33 D06N3/00 C08L97/02 

FIELD: textile, paper.

SUBSTANCE: method of compacting a fibrous material includes adding to a fibrous material a binder selected from the group consisting of water-soluble binders, water-swelling binders, and binders with a glass transition temperature of less than 25°C. A combination of a fibrous material and a binder is obtained. A combination of a fibrous material and a binder is made to produce a densified fibrous material having a bulk density that is at least about twice the bulk density of the fibrous material. Fibrous material prior to compaction has a bulk density of less than 0.15 g/cm³, which is determined according to the ASTM D1895B method. This fibrous material is obtained by cutting fibrous raw materials from cellulose or lignocellulosic materials, including herbs, rice husks, bagasse, cotton, jute, hemp, flax, bamboo, sisal, straw, sawdust, paper, manila hemp, wood, coconut fiber, corn cobs.

EFFECT: invention makes it possible to obtain a densified fibrous material of the required density.
