ABSTRACT:
A non-woven fabric is produced by stretching the film with on one surface a regular pattern of raised areas such as spaced hexagonal bosses and on the other surface a plurality of parallel grooves. Stretching is carried out in the groove direction. Preferably the polymer is a mixture of incompatible polymers so that on stretching a fibrous structure is formed. The film can be produced by melt-embossing. The stretched non-woven fabric may be coated with various adhesives to provide a tape useful in a medical context.
