SYNTHETIC RESIN FIBER KNEADED WITH NON-FIBER POWDER AND SYNTHETIC RESIN SHEET RAW MATERIAL

摘要

PURPOSE:To obtain the title raw material having excellent hygroscopic and moisture releasing properties, steam permeability and having a new handleability and contact feeling similar to natural raw material without dewing even in low temperature atmosphere by kneading a zootic or vegetative non-fiber material formed into ultrafine powder with a polymer of chemical fiber raw material. CONSTITUTION:The objective raw material obtained by blending (A) zootic or vegetative non-fiber material (e.g. bark) formed into ultrafine powder with (B) polymer of chemical fiber raw material consisting of linear polymer of (semi)-synthetic fiber or regenerated fiber or blend of two or more kinds of polymers thereof. The raw material is spun so as to apply to a semi-cured other fiber surface in a sheath shape to provide a fiber having core-sheath structure. Cloth or nonwoven fabric obtained by weaving or knitting the resultant fiber is fused or bonded to the surface of synthetic resin sheet to provide a sheet-like fiber sheet.
