摘要： A laminate consisting of at least three layers, one layer of the laminate being formed by at least one nonwoven web made from continuous filaments. This is a nonwoven web thermally hardened by means of the effect of a hot fluid. A further layer of the laminate is disposed both on the upper side and on the lower side of the nonwoven web and connected securely to the nonwoven web.

摘要： An apparatus for making spunbond from continuous thermoplastic filaments has a spinneret for spinning the continuous filaments and advancing them in a filament-travel direction, a cooler for cooling the filaments, a stretcher for stretching the filaments, a depositing device including a foraminous belt extending in a machine direction transverse to the filament-travel direction for deposition of the filaments as a nonwoven web and conveyance away from the stretcher, a diffusor between the stretcher and the foraminous belt so that filaments and primary air from the stretcher enter into the diffusor, and a suction device for extracting air through the foraminous belt at an unobstructed extraction region underneath the diffusor outlet and having a width b in a machine direction that is greater than a width B of the diffusor outlet. The diffusor forms upstream and downstream secondary air-inlet gaps at opposite ends through which secondary air is aspirated into the diffusor.

摘要： An apparatus for making a spunbond nonwoven laminate having a plurality of spunbond nonwoven layers has a row extending in a travel direction of two, three, or four spinning beams each emitting a multiplicity of multicomponent crimped continuous filaments with the filaments of each beam having a degree of crimp different from that of the filaments of each of the other beams. Respective extruders supply each beam with the components of the respective filaments and respective supply units feed each of the extruders with the respective components. The rate at which the components are supplied to the extruders is adjusted for varying the proportions of the components in each filament. A conveyor extends in the direction below the beams and receives the filaments as respective layers from the respective beams.

摘要： 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 %.

摘要： A nonwoven web is made by displacing an air-permeable mesh-belt conveyor in a horizontal travel direction and spinning and then depositing crimped continuous filaments as a web at a deposit region on the air-permeable mesh-belt conveyor. A first preconsolidation stage is provided downstream of the deposit region and a second preconsolidation separated by a suction gap from the first stage. Air is drawn air through the web and the conveyor at the deposit region at a first predetermined speed, the first and second consolidation stages at a second and third predetermined speeds, and at the suction gap either not at all or at a fourth predetermined equal to at most substantially less than the second predetermined speed.

摘要： A spunbond nonwoven laminate has a first spunbond nonwoven layer having crimped filaments formed by a first component on an outer surface of the filaments of the first layer consisting or substantially consisting of a polyolefin and a second component consisting or substantially consisting of a plastic having a higher melting point than the polyolefin of the first component of the filaments of the first layer. A second outermost spunbond nonwoven layer on the first layer having filaments as a cover layer and formed by a first component on an outer surface of the filaments of the second layer consisting or substantially consisting of a polyolefin, and a second component consisting or substantially consisting of a plastic having a higher melting point than the polyolefin of the first component of the filaments of the second layer.
