A nonwoven web is made by first depositing fibers as a nonwoven web in a deposition area, then conveying the web away from the deposition area in a web-travel direction, preconsolidating the web in the path, and passing the preconsolidated web between a pair of rollers that compress and final consolidate the preconsolidated web, One of the rollers is separated from the web such that final consolidation of the web at a starting level is stopped and at the same time or immediately beforehand upstream preconsolidation of the web increased. After separating the one roller from the web, another roller is engaged with the web at the consolidation station and then final consolidation is recommenced, whereupon upstream preconsolidation of the web is reduced back to the starting level.

The present invention discloses a silencer for automobile. The silencer is formed by press molding. The silencer has a first molded surface and a second molded surface which are opposite to each other in a thickness direction. The silencer at least includes a first fiber layer on which the first molded surface is formed and a second fiber layer integrated with an opposite surface to the first molded surface, the opposite surface being on the first fiber layer. Fibers of the second fiber layer exist partly on the opposite surface on the first fiber layer.

The invention relates to a method of forming a biodegradable nonwoven fabric, the nonwoven fabric obtained by this method, and a system of devices for carrying out this method, to be used for the manufacture of cellulosic articles for clean-up work and sanitary products, and medical uses.

A nonwoven biofabric comprises a web comprising (a) biodegradable polymeric melt blown fibers, and (b) a plurality of particles enmeshed in the biodegradable polymeric meltblown fibers.

The invention relates to a textile fabric made of a fleece comprising a super absorbing activation, to a method for producing the textile fabric, to a covering surrounding the textile fabric, to a cooling system using the covering and to a covering designed as a cooling item.

A spunbond nonwoven laminate has a plurality of stacked spunbond nonwoven layers, namely at least two and at most four spunbond nonwoven layers that have crimped continuous filaments or consist of crimped continuous filaments. The degree of crimping of the filaments is different in each of these spunbond nonwoven layers, and each of the crimped filaments of the spunbond nonwoven layers has a crimp with at least two, preferably at least three, and more preferably with at least four loops per centimeter of length. The crimped filaments of the spunbond nonwoven layers are multicomponent filaments, particularly bicomponent filaments, with a first plastic component and a second plastic component present in the respective filament in a proportion of at least 10 wt %.
