WIPING SHEET AND PRODUCTION THEREOF.

摘要

DISCLOSED HEREIN IS A WIPING SHEET COMPOSED OF TWO PIECES OF SPUNLACE NONWOVEN FABRICS (.1) CONTAINING HEAT-SHRINKABLE FIBER WHICH ARE FUSION-BONDED TOGETHER WITH FUSION-BONDING LINES (2) WHICH EXTEND IN THE CROSS DIRECTION (CD) PERPENDICULAR TO THE MACHINE DIRECTION (MD). THE FUSION-BONDING LINES (2) ARE FORMED SUCH THAT THEIR PITCH (P) IN THE MACHINE DIRECTION (MD) IS SHORTER THAN ONE HALF OF THE FIBER LENGTH SO THAT EACH FUSION-BONDING LINE (2) INTERSECTS A SINGLE FIBER AT 3 OR MORE POINTS. THIS STRUCTURE PREVENTS SURFACE FLUFFING AND IMPARTS A HIGH SURFACE FRICTIONAL STRENGTH AND A HIGH BENDING RESISTANCE FOR COMFORTABLE WIPING WORK.
