Abstract
The invention relates to a nonwoven fabric sheet comprising at least two adjacent layers of spunbonded nonwoven webs, one of which is an elastic layer in the form of a spunbonded nonwoven web comprising elastic fibers formed from a thermoplastic elastomer polymer material. The invention further relates to a method of manufacturing such nonwoven and the use of such nonwoven.
Claims21
A nonwoven fabric sheet comprising at least three adjacent layers of spunbonded nonwoven webs,
- wherein a first one of the three layers is a first carrier layer in the form of a spunbonded nonwoven web comprising crimped multicomponent fibers,
- wherein a second one of the three layers is an elastic layer in the form of a spunbonded nonwoven web comprising elastic fibers formed from a thermoplastic elastomer polymer material;
- wherein a third one of the three layers is a second carrier layer in the form of a spunbonded nonwoven web comprising crimped multicomponent fibers, and wherein the elastic layer is sandwiched between the first and second carrier layer;
- and
- wherein the web of each of the first carrier layer and the second carrier layer comprises a pattern of macroscopic bonding points, while the web of the elastic layer is devoid of macroscopic bonding points, and the elastic layer is adhered to each of the first carrier layer and the second carrier layer due strictly to an initial tackiness of the elastic layer.
