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.

The invention relates to a nonwoven laminate fabric comprising a meltblown nonwoven layer sandwiched between first and second spundbond nonwoven layers, wherein at least one of the spundbond layers is a high loft spunbond nonwoven layer comprising or consisting of crimped multicomponent fibers.

Netting (100) comprising an array of polymeric strands (101, 102), wherein the polymeric strands (101, 102) are periodically joined together at bond regions (105) throughout the array with spaces (103, 109) between adjacent strands, wherein at least a plurality (i.e., at least two) of the strands are hollow polymeric strands (i.e., a hollow core (106) with a sheath (107) surrounding the hollow core), and wherein at least 50 percent by number of the strands do not substantially cross over each other. In some embodiments, the core comprises fluid. Embodiments of nettings described herein are useful for example, for thermal transport in thermal interface articles used to control the temperature of and/or dissipate heat for electronic components and batteries or mechanical devices.

A spunbonded nonwoven laminate comprising at least two spunbonded nonwoven layers made of continuous filaments, wherein at least one crimped spunbonded nonwoven layer comprising bulked continuous filaments is present. The bulked continuous filaments of the at least one crimped spunbonded nonwoven layer are multicomponent filaments comprising at least one first polymer component and at least one second polymer component. At least one reinforcing spunbonded nonwoven layer which consists or substantially consists of non-bulked continuous filaments and/or continuous filaments that are less bulked in comparison with the continuous filaments of the at least one crimped spunbonded nonwoven layer is present. The continuous filaments of the reinforcing spun-bonded nonwoven layer comprise at least one binder component arranged at their surface. The melting temperature difference between the binder component of the continuous filaments of the reinforcing spunbounded nonwoven layer and the first polymer component of the continuous filaments of the at least one crimped spunbounded nonwoven layer is less than 15 C. The laminate has a maximum cantilever flexural strength of at most 100 mm.

The invention relates to a method for producing a nonwoven fabric comprising at least one nonwoven web composed of fibres. The fibres are produced by means of at least one fibre-producing device. Subsequently, the fibres are deposited on at least one depositing device in order to form the nonwoven web. The nonwoven web or nonwoven fabric is solidified with at least one calender roller, and the nonwoven fabric is also solidified or primarily solidified with at least one hot fluid primary solidification device.

A method of creating a soft and lofty continuous fiber nonwoven web is provided. The method includes providing molten polymer to a spinneret defining a plurality of orifices, and flowing a fluid intermediate the spinneret and a moving porous member. The moving porous member is positioned below the spinneret. The method includes using the fluid to draw or push the molten polymer, in a direction that is toward the moving porous member, through at least some of the plurality of orifices to form a plurality of individual continuous fiber strands. The method includes depositing the continuous fiber strands on the moving porous member at a first location to create an intermediate continuous fiber nonwoven web, and removing and/or diverting some of the fluid proximate to the first location to maintain loft and softness in the deposited intermediate continuous fiber nonwoven web.
