  • Patent number: 7064242
    Abstract: A patch comprising a backing layer and a adhesive layer formed on the back face of the backing layer wherein a woven fabric or a nonwoven fabric made of a rayon and pulp fiber mixture is employed as the backing layer and the mixing ratio thereof is from 3:7 to 7:3. When employed in taping a finger, a wrist, an ankle, neck, an elbow, a knee or the like, the patch would not soon curl up or peel off at an overlapping part. After the patch is adhered and then stripped off, no fiber piece remains on the pressure-sensitive adhesive face of the backing layer so that the adhesive force of the patch can be sustained in the case of re-adhesion.
