COMPOSITE SHEET AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To prepare a composite sheet which is uniformly distributed with many continuous fibers on a base layer. SOLUTION: The composite sheet used as a sheet 1 for cleaning, or the like, is formed by joining the base layer 7 and the continuous fibers 8a formed as groups at joint lines 5. The joint lines 5 consist of the first joint lines 5A formed on one side of an axis C-C bisecting the width of the groups of the continuous fibers 8a and the second joint lines 5B formed on another one side. The first and second joint lines 5A and 5B intersect diagonally with the groups of the continuous fibers 8a so as to extend toward the axis C-C and intersect diagonally with each other.
