Abstract

The present invention provides a body-adhesive tape having adhesive properties preventing the tape from peeling off due to sweat when it is applied in an overlapped manner, and which also has good moisture permeability. In the body-adhesive tape, a base cloth is formed from a stretchable warp thread and a standard weft thread. On one side of the base cloth a plurality of pressure-sensitive adhesive layers are formed separated by appropriate gaps. The pressure-sensitive adhesive layers are formed so that they meander left and right along the length of the tape. At the gaps, the base cloth is exposed so there is permeability. Since the gap meanders, it is longer than the tape, and thus there is more exposure of the weave and more permeability. The pressure-sensitive adhesive layers meander so that the tape can be attached anywhere on the body and can respond to tension due to body movement from any direction. Base cloth is processed for water repellency so that the tapes can be attached in an overlapping manner and no sweat or the like will be absorbed, and the upper tape will not tend to peel off.

Claims

1. A body-adhesive tape comprising:

a water-repellent base cloth formed from a warp thread and a weft thread;

said warp thread including a stretch thread twisted together with a standard fiber;

said weft thread being a non-elastic thread;

a plurality of wavy strip-shaped pressure-sensitive adhesive layers formed on one side of said base cloth;

said adhesive layers arranged in rows separated by prescribed gaps;

said base cloth being exposed in said gaps;

said adhesive layers varying in width at a plurality of locations along said length in a direction transverse to said length of said tape;

said adhesive layers and said gaps covering substantially the whole surface of said tape;

said base cloth having lower permeability at portions on which said pressure-sensitive adhesive layers are formed; and

said base cloth having higher permeability at said prescribed gaps separating said adhesive layers.

2. A body-adhesive tape as described in claim 1, wherein said pressure-sensitive adhesive layer includes an acrylic-based synthetic resin.
