Abstract
Machine for producing a patterned textile product, comprising a drum with a perforated lateral surface rotated about its axis, a sleeve with holes which is slipped over the drum, and having a ration of the sum of the surface area of the holes to the surface area of its total lateral surface of between 5 and 75% and, preferably, between 7 and 50% and a hole diameter not greater than 1 mm, a device for spraying water jets in the direction of the drum in a direction substantially radial thereto and means for creating a vacuum inside the drum wherein an apertured sheath is slipped over the sleeve and has apertures at least one dimension of which is greater than 2 mm.
Claims16
A nonwoven which comprises entangled filiform elements with free ends and in which patterned projecting parts are embossed, wherein the free ends of the filiform elements project from the patterned parts over a length of less than 1 mm and the number of these ends is less than 10/5 mm2, the patterned parts are columnar and have flat upper faces produced as a result of being embossed against a restraining surface, and the filiform elements project from the upper faces of the patterned parts.
A nonwoven which comprises entangled filiform elements with free ends and in which patterned projecting parts are embossed, wherein the patterned part has a columnar shape, extending to an upper face resulting from being shaped against a restraining surface and from fluid passing through the nonwoven and the restraining surface, the free ends of the filiform elements project from the upper faces of the patterned parts, and the free ends of the filiform elements project from the patterned parts over a length of less than 1 mm and the number of these ends is one or more and less than 10/5 mm 2.
A nonwoven comprising entangled filiform elements having free ends, the nonwoven includes an upper surface intermediate embossed patterned projecting parts that extend from the upper surface, the patterned projecting parts have flat upper faces except for projecting free ends of the filiform elements, and the projecting free ends of the filiform elements extend from the flat upper faces of the patterned parts over a length of less than 1 mm and the number of free ends projecting from the flat faces is less than 10/5 mm2.
