A thermoformable non-woven material that meets at least one of the UL94 V-0 (2013) flammability standard and the ASTM E84-14 (2014) flammability standard. The material may include charring fiber having a denier per fiber at least about 3 and binding fiber having a denier per fiber between about 1 and about 8. The weight ratio of charring fiber to binding fiber may be between about 2:1 and about 4:1, and the denier per fiber of the charring fiber may be at least about twice the denier per fiber of the binding fiber.

The current invention relates to a multitubular sheathing for electrodes of industrial batteries, which defines a plurality of longitudinal pockets receiving the terminals of an electrode inside, said sheathing being made of non-woven fabric formed from staple fibers made integral with one another, wherein the surface of said sheathing contacting said terminals exhibits a contact layer of non-woven fabric having at least 10% of fibers in a tangential direction. The invention further relates to a process for making said multitubular sheathing.

An external material for vehicles may include a non-woven fabric having a honeycomb structure and a wheel guard including the same.

A flash spinning method for preparing non-woven fabrics based on microwave thermal fusion, a microwave thermal fusion device, and a non-woven fabric preparation device are provided. The flash spinning method includes: step S1, collecting filament bundles to form a non-woven fabric precursor, adding a microwave heating liquid to the non-woven fabric precursor; the microwave heating liquid being configured to absorb microwave energy and convert the microwave energy into thermal energy; and step S2, performing microwave heating on the non-woven fabric precursor containing the microwave heating liquid obtained in the step S1 to obtain a heated non-woven fabric, and performing a hot press forming treatment on the heated non-woven fabric to obtain a finished non-woven fabric. There is no temperature gradient in layers of the non-woven fabric precursor, thereby significantly improving the peeling strength of the finished non-woven fabric.

The invention relates to a shield comprising: a thermo-compressed porous three-dimensional shell based on glass fibers, the fibers being joined together by a binding agent. The shield includes a foam-based inner spring layer, and additionally has the following features: the foam layer is produced by reaction injection molding (RIM), the layer overmolding the shell. The shell has a porosity arranged in order to enable the foam to penetrate a fraction of the thickness of the shell, so as to create a leaktight skin the binding agent is based on polypropylene. The shell comprises between 45 and 55% by weight of glass fibers.

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.
