Abstract: The clothing (1) comprises a first layer (2) with a first thread arrangement (4) oriented in a longitudinal direction of the clothing, and a second layer (5) with a second thread arrangement (6), which is aligned at an angle to the longitudinal direction of the clothing and is characterized by a constant thread density in the longitudinal direction. The first thread arrangement is implemented and arranged, so that areas with different liquid permeabilities are produced transverse to the longitudinal direction of the clothing. The second layer is bonded with the first layer. The clothing (1) comprises a first layer (2) with a first thread arrangement (4) oriented in a longitudinal direction of the clothing, and a second layer (5) with a second thread arrangement (6), which is aligned at an angle to the longitudinal direction of the clothing and is characterized by a constant thread density in the longitudinal direction. The first thread arrangement is implemented and arranged, so that areas with different liquid permeabilities are produced transverse to the longitudinal direction of the clothing. The second layer is bonded with the first layer. The second thread arrangement is oriented transverse to the longitudinal direction of the clothing. A constant distance (a) is provided between the individual threads of the second thread arrangement and the individual threads are made of same material with same geometrical design and dimensions. The individual threads of the thread arrangements are introduced on a carrier, embedded into the carrier and/or bonded with the carrier, where the carrier is formed as non-woven, woven fabric, tissue, scrim or substrate. The connection between the threads of the thread arrangements and the structure surrounding the thread arrangements is produced by needling and is thermally produced by melting. The clothing comprises additional layers with the thread arrangements oriented in longitudinal direction and/or transverse direction and the individual layers are alternatively arranged with the thread arrangements oriented in the longitudinal direction and/or transverse direction. The additional layer is formed as non-woven, knitted fabric, woven fabric, tissue, scrim or substrate. The thread of the first thread arrangement oriented in the longitudinal direction of the clothing is arranged with the thread density of 8-12 Fd/cm, vary in their geometric shape, dimensions and/or material in cross-section, and is symmetrically or asymmetrically arranged with different densities transverse to the longitudinal direction. The thread of the second thread arrangement oriented in the transverse direction of the clothing is arranged with a constant density of 8.5 Fd/cm. The individual threads of the thread arrangements oriented in the longitudinal and/or transverse direction of the clothing are formed as monofilament and multifilament or are formed in an implementation of several components with a cover and core or in the form of a twisted yarn or yarn, and consist of elastic polymer. An independent claim is included for a method for manufacturing a clothing useful in a machine for producing and/or processing of material webs with profile correction of multiple layers.
