CONJUGATE FIBER AND FIBROUS SHEET USING THE SAME CONJUGATE FIBER

摘要

PROBLEM TO BE SOLVED: To obtain a conjugate fiber bondable in only points where the mutual fibers intersect and suitable for production without forming into a filmy or a massive shape and without sticking to heated rolls or conveyors and a fibrous sheet using the conjugate fiber and excellent in air permeability, liquid permeability or resin impregnating properties. SOLUTION: This conjugate fiber contains a crystalline resin and an amorphous copolyester containing 1,4-cyclohexanedimethanol as a diol component. The amorphous copolyester occupies at least a part of the fiber surface. The conjugate fiber is contained in the fibrous sheet.
