摘要： Aspects of the present disclosure relate to methods and apparatuses for relofting nonwoven substrates. During the relofting process, a substrate is directed to advance in a first direction such that a length of the substrate is in a facing relationship with a radiation source. The advancing substrate is relofted by irradiating the length of the substrate with infrared radiation from the infrared radiation source. The substrate comprises a first caliper upstream of the radiation source and the substrate comprises a second caliper downstream of the radiation source greater than the first caliper. The substrate may also be redirected around an axis to advance the substrate in a second direction, wherein the second direction is different than the first direction. The axis may be selectively movable between a first position and a second position to selectively subject the substrate to infrared radiation and remove the substrate from the infrared radiation.

摘要： A composite flame barrier includes at least one layer of nonwoven flame resistant fibers, and at least one layer of heat absorbing intumescing expandable graphite held together with polymeric binders and fire resistant fibers in a sheet structure. The composite material provides thermal protection that cannot be achieved using the expandable graphite is alone. By mechanically attaching a nonwoven felt or hydro-entangled nonwoven material to the layer containing expandable graphite, the graphite becomes stabilized and is more resistant to forces that may damage the material (wind, high velocity flames etc.) and decrease or eliminate the thermal performance of the expandable graphite. The composite flame barrier is useful in applications where prolonged fire and heat resistance is required, and has an advantage of being flexible and lightweight. The uses for the material include emergency portable fire shelters, structural protection of aircraft, structural steel fire proofing, fire-rated wall assemblies, and other fire-resistant applications.

摘要： Dimensionally stable nonwoven fibrous webs include a multiplicity of continuous fibers formed from one or more thermoplastic polyesters and polypropylene in an amount greater than 0% and no more than 10% by weight of the web. The webs have at least one dimension which decreases by no greater than 10% in the plane of the web when heated to a temperature above a glass transition temperature of the fibers. A spunbond process may be used to produce substantially continuous fibers that exhibit molecular orientation. A meltblown process may be used to produce discontinuous fibers that do not exhibit molecular orientation. In some embodiments, the fibers comprise a viscosity modifier and/or an anionic surfactant. The webs may be used as articles for filtration, sound absorption, thermal insulation, surface cleaning, cellular growth support, drug delivery, personal hygiene, medical apparel, or wound dressing.

摘要： A composite fiber having elastomer and method for making the same, and a substrate having the composite fiber and method for making the same are provided. The composite fiber includes a first composition and a second composition. The first composition is thermoplastic non-elastomer, and the second composition is thermoplastic elastomer (TPE). The second composition is in an amount of 5 to 70 weight % of the composite fiber. The first composition and the second composition are alternately distributed in a circumference of a cross-section of the composite fiber, and the length of the second composition is less than 50% of the total length of the circumference. The TPE can be dispersed uniformly and increase the adhesion between fibers, and the segmented fiber cross-section thereof further prevents the TPE from becoming too adhesive and affecting the processing during the fabrication of fibers and non-woven fabric substrates. Therefore, the non-woven fabric substrate or artificial leather made from the composite fiber has excellent textile feeling and physical properties.

摘要： A sheet of nonwoven fabric which has surface irregularities, the shape of the surface irregularities being less apt to be changed by external pressure, etc. The sheet has a machine, cross and thickness directions which are perpendicular to one another. The upper surface has a plurality of protrusions continuously extending, in parallel, in the cross direction and further has a plurality of recesses that are located between the adjacent protrusions and extend in the cross direction. The sheet includes first and second fibrous layers located on the upper-surface side and the lower-surface side, respectively. The first fibrous layer comprises heat-fusible fibers, and the second fibrous layer comprises coil-shaped three-dimensional crimp fibers that are oriented mainly in the machine direction and form a network by entanglement thereof without having been fused at the sites where the crimp fibers cross one another.
