A glass fiber mat comprises glass fibers of a first kind, glass fibers of a second kind and a binding agent. Glass fibers of the first kind in this case are characterized by a mean fiber diameter of under 6 m and compliance with the EC Protocol ECB/TM/27 rev. 7 and glass fibers of the second kind by a mean fiber diameter of over 6 m. The ratio between the weight component of glass fibers of the first kind and the weight component of glass fibers of the second kind is between 0.01 and 0.15. And the surface weight of the glass fiber mat is between 25 g/m2 and 80 g/m2. In a CV floor covering comprising a usable layer and a structural layer, the structural layer comprises a glass fiber mat of this kind provided with impregnation.

Aspects herein relate to apparel items and apparel systems that utilize applied or printed foam nodes to provide, among other things, stand-off between an apparel item and a wearer's skin surface. One or more of the foam nodes, or areas of the textile surrounding the foam nodes, may be perforated to provide a fluid communication path between an inner-facing surface and an outer-facing surface of the apparel item. The communication path may be used to facilitate air exchange between the external environment and the wearer's body and/or to provide an exit path for moisture vapor generated by the wearer.

A host of new silk material formats are disclosed, all prepared from an initial liquid composition including both silk fibroin and xanthan gum. In some cases, particularly preferred material properties are achieved by the addition of glycerol. These various formats include liquids, whipped silk creams, silk meringues, and compressed/heat-compressed meringues. Among the useful end-uses for these materials is a silk leather, which mimics the feel of conventional leather. Other uses include thermal insulation, absorption/gas sensing, biological scaffolding, and the like. A material that has material properties unexpectedly similar to mycelium is also disclosed.

The invention relates to a tile, in particular a carpet tile. The invention also relates to the use a tile according to the invention as floor tile, wall tile, or ceiling tile. The invention further relates to a tile covering consisting of a plurality of tiles according to the invention. The invention additionally relates to a carpet covering consisting of at least one carpet tile according to the invention.

A foamed rubber shoe material is obtained from a rubber shoe base material by vulcanization, foaming, and cutting, the rubber shoe base material includes a rubber sheet and a cloth attached on the rubber sheet, the rubber sheet is prepared from a premixed rubber material in an open mill, the premixed rubber material includes the following components in parts by weight: 44-48 parts of rubber matrix, 24-28 parts of a filler, 5-7 parts of an oil material, 4-5 parts of a vulcanization agent, 1.8-2.2 parts of an antiager, 0.5-0.7 parts of an accelerator, 4-6 parts of triterpenoid saponin, 8-12 parts of n-butanol, 3-5 parts of an unsaturated fatty acid, 7-9 parts of sulfur, 1.6-2.4 parts of dicumyl peroxide, and 10-14 parts of a foaming agent, the foaming agent includes a combination of 4,4-oxybis(benzenesulfonyl hydrazide), petroleum ether, dichloroethane and at least one bicarbonate, and the rubber matrix includes a natural rubber.

A damping layer comprises a large number of yarns combined to form a textile, wherein at least some of the yarns are foamed synthetic yarns. Such a textile, which consists of a mix of foamed and non-foamed synthetic yarns, is relatively strong and light and can lead to more efficient use of the foamed material. The foamed synthetic yarn may be formed into upstanding loops which provide additional resiliency and damping.

Mass production of carpet tiles can be enabled by a method for manufacturing a carpet tile by applying an adhesive layer to a carpet tile base material containing pile, the method including: a first process of mixing 15 to 25 wt. % of urethane resin glue to an acrylic foamed resin to produce 100 wt. % of a mixture, thereby obtaining an adhesive; a second process of subjecting the adhesive to viscosity adjustment to adjust viscosity thereof to 3000 to 6000 cps; and a third process of applying the adhesive to the carpet tile base material by using a screen mesh having a mesh thickness of 20 m or more and less than 100 m and an opening area ratio of 40% to 60%.

The present disclosure generally relates to polymer-aerogel/fiber composite materials, polymer-aerogel/textile composite materials, and systems and methods for producing them. The gel material can comprise, in some embodiments, a network of polymer. The fiber and/or textile material can comprise at least one of any natural, synthetic, and/or mineral fiber. In some cases, certain combinations of materials, solvents, and/or processing steps may be synergistically employed so as to enable manufacture of materials suitable for use in apparel, soft goods, and other consumer applications which may benefit from the properties of a polymer-aerogel/fiber composite and/or the polymer-aerogel/textile composite.

A foamed, opacifying element has a porous substrate composed of woven yarn strands composed of a thermoplastic polymer-coated multifilament core. It has a dry foamed composition on an opposing surface of the substrate, which includes: (a) 0.1-40 weight % of porous particles; (b) 10-80 weight %; (c) 0.2-50 weight % of one or more additives selected from the group consisting of dispersants, plasticizers, flame retardants, optical brighteners, thickeners, biocides, fungicides, tinting colorants, metal flakes, and inert inorganic or organic fillers; (d) less than 5 weight % of water; and (e) at least 0.002 weight % of an opacifying colorant different from all of the one or more additives of (c), which opacifying colorant absorbs electromagnetic radiation having a wavelength of 380-800 nm.
