Abstract
The present invention relates to a self-adhesive dressing comprising a layer (1) of spunlace nonwoven material and attached thereto a layer (2) of adhesive. In accordance with the invention, the dressing is stretchable in a first direction (MD) corresponding to the machine direction of the nonwoven material and in a second direction (CD) perpendicular to the first direction, in conjunction with which the resistance to stretching is less than 10 N/25 mm in both the first (MD) and the second (CD) directions in the case of stretching of less than or equal to 5%.

A self-adhesive dressing comprising:
- a layer (1) of spunlace nonwoven material and attached thereto a layer (2) of adhesive, wherein the dressing is stretchable in a first direction (MD) corresponding to a machine direction of the nonwoven material and in a second direction (CD) perpendicular to the first direction, in conjunction with which a resistance to stretching is less than 10 N/25 mm in both the first (MD) and the second (CD) directions in a case of stretching of less than or equal to 5%, and in that a quotient
- the resistance to stretching in the first direction (MD)
- the resistance to stretching in the second direction (CD)
- is equal to or less than 7 in the case of stretching of less than or equal to 5%.
A method for producing a self-adhesive dressing comprising a layer (1) of spunlace nonwoven material and attached thereto a layer (2) of adhesive, which dressing is stretchable in a first direction (MD) corresponding to the machine direction of the nonwoven material and in a second direction (CD) perpendicular to the first direction, characterized in that a layer of nonwoven material (1) is stretched in the second direction (CD) or is compressed in the first direction (MD), whereupon the nonwoven material (1) is coated with a layer (2) of adhesive.
