Patent number: 11702780Abstract: An apparatus for making a nonwoven fabric from thermoplastic fibers has a spinneret for spinning fibers into continuous filaments and a cooler for cooling the filaments. The cooled filaments are then deposited on a conveyor to form a nonwoven web. A first consolidator surface treats the nonwoven web with a hot fluid or hot air as it is conveyed on the conveyor. A second consolidating downstream of the first consolidator has a dual-belt furnace in which the nonwoven web is passed between two circulating belts or continuous belts for surface treating the nonwoven web with a hot fluid or hot air and for applying surface pressure can be applied to the nonwoven web at the same time.Type: GrantFiled: March 29, 2021Date of Patent: July 18, 2023Assignees: REIFENHAEUSER GMBH & CO.

Patent number: 11383481Abstract: A laminate is made by first making by melt-blowing or spunbonding of multicomponent, thermoplastic, and endless filaments a first nonwoven layer lying generally in a plane and having a predetermined shrinkage capacity or potential parallel to the plane and making of thermoplastic and endless filaments a second nonwoven layer also lying generally in a respective plane and having a shrinkage capacity or potential that is smaller than that of the first nonwoven layer. The two layers are directly juxtaposed flatly on each other, and the directly juxtaposed first and second layer are bonded together only at bonded regions while leaving an array of unbonded regions distributed over a surface of the two bonded-together nonwoven layers. Then only the first nonwoven layer is shrunk so that the second layer bunches in the unbonded regions and is there raised transverse to a plane of the bonded-together layers.Type: GrantFiled: January 9, 2017Date of Patent: July 12, 2022Assignees: REIFENHAEUSER GMBH & CO.

Patent number: 10995436Abstract: The invention relates to a method for producing a nonwoven fabric from fibres, wherein the fibres are spun by means of at least one spinneret, are cooled and then deposited on a collection device to form a nonwoven web. The nonwoven web undergoes hot fluid bonding during at least two consecutive bonding steps. In a first bonding step, the surface of the nonwoven web is subjected to a hot fluid and, in a second bonding step, the surface of the nonwoven web is also subsequently subjected to a hot fluid and, in addition and at the same time, surface pressure is exerted on the nonwoven web.Type: GrantFiled: February 23, 2018Date of Patent: May 4, 2021Assignees: REIFENHAEUSER GMBH & CO.

Publication number: 20210054550Abstract: A package has walls formed of a weldable spun-bonded nonwoven and having welded wall regions. The spun-bonded nonwoven has continuous filaments of a thermoplastic plastic each with a thermoplastic core surrounded by a thermoplastic sheath. The sheaths of the continuous multicomponent filaments of both components contain at least 3 wt % of at least one filler so that weldability of the spun-bonded nonwoven is improved by reducing a welding temperature in thermal welding of the spun-bonded nonwoven. A first plastic component forming the sheaths of the multicomponent filaments has the same or a lower melting point than a second plastic component forming the cores of the filaments.Type: ApplicationFiled: November 9, 2020Publication date: February 25, 2021Inventors: Claudio CINQUEMANI, Alexander KLEIN
