Abstract
A disposable wipe-out sheet that includes a plurality of long fibers bonded to a heat-sealable base sheet by sealing lines. The long fibers include groups continuously extending between each pair of the adjacent sealing lines to form bridge-like portions and groups severed in two sections between each pair of the adjacent sealing lines so as to fluff upward on the base sheet.
Claims3
A process for making a disposable wipe-out sheet comprising a heat-sealable base sheet and a plurality of heat-sealable fibers heat-sealed with said base sheet and extending in one direction, said process comprising the steps of:
- providing a heat-sealable base sheet and a plurality of heat-sealable fibers which extend in a first direction;
- bonding said fibers to said base sheet by a plurality of sealing lines extending in a second direction which crosses said first direction, said plurality of sealing lines being arranged intermittently in said first direction so as to form an assembly of said fibers and said heat-sealable base sheet;
- and
- pressing a cutter against said assembly of said fibers and said heat-sealable base sheet so that a plurality of first groups of said fibers extending between adjacent pairs of said sealing lines have respective lengths thereof that are severed into two sections and at substantially the same time said heat-sealable base sheet is formed with slits said heat-sealable base sheet being molten and solidified along peripheral edges of said slits.
