A dispensable nonwoven cohesive wrap that is generally dispensed from a self- wound roll. The nonwoven cohesive wrap comprises mutually entangled fibers at least some of which are pressure-sensitive adhesive fibers. The cohesive wrap also generally has a basis weight of from 40 to 200 grams/m2, a tensile strength of at least 100 grams/2.5 cm and a T-peel from itself of from 1 to 30 grams/2.5 cm. The wrap is preferably a single layer material without a separate adhesive coating or release coating where the adhesive fibers extend through the entire depth dimension of the wrap, such that a portion of the adhesive fibers are on both faces of the wrap, and preferably are uniformly distributed across the length and width dimensions of the wrap.

L'invention concerne un bandage cohésif non tissé pouvant être délivré que l'on peut généralement dérouler d'un rouleau. Le bandage cohésif non tissé comprend des fibres mutuellement enchevêtrées dont au moins certaines sont des fibres adhésives autocollantes. Le bandage cohésif présente généralement un poids de base s'échelonnant entre 40 et 200 g/m<2>, une résistance à la traction d'au moins 100 g/2,5 cm et un pouvoir adhésif ("T-peel") sur lui-même s'échelonnant entre 1 et 30 g/2,5 cm. Le bandage est de préférence une matière monocouche sans revêtement adhésif séparé ou revêtement de libération, les fibres adhésives s'étendant à travers toute la profondeur du bandage de manière qu'une partie des fibres adhésives se trouve sur les deux faces du bandage et que les fibres soient réparties uniformément sur la longueur et la largeur du bandage.
