Embodiments of the invention provide fiber mat facers, ceiling panels, and method of manufacturing the same. A fiber mat facer may include a non-woven web of fibers having a first group of fibers with an average fiber diameter from about 6 m to about 20 m and a second group of fibers with an average fiber diameter from about 0.5 m to about 5 m. The fiber mat facer may also include a binder to bond together the non-woven web of fibers into the fiber mat. The binder may include a water repellant additive. The binder and/or fiber mat facer may further include an additive that enhances the opacity of the fiber mat facer. The fiber mat facer may also include a paint applied to an outer surface of the facer. The paint may include an additive that enhances the visual appeal of the facer and/or ceiling panel.

A cable wrapping tape, in particular for the engine compartment of an automobile, has a strip-like carrier (1) consisting of fabric, said carrier is provided at least on one side with a self-adhering adhesive layer (2) which consists of a pressure-sensitive adhesive, wherein the fabric of the carrier (1) consists of a yarn (3a, 3b) which is formed from a polyamide material and which has a yarn strength of at least 280 dtex. The yarn (3a, 3b) is formed from 24 to 80 filaments (4), and the cable wrapping tape meets abrasion class E according to LV 312 both on a mandrel having a 5 mm diameter and on a mandrel having a 10 mm diameter. For increasing the abrasion resistance, it is proposed that the filaments (4) are twisted with one another about a central longitudinal axis (X-X) of the yarn (3a, 3b).

A passive electrical article including a dielectric layer having a nonwoven material.

A composite resin tank includes a wall joined to a dome along a joint. A softening strip is used to control stress in the joint.

A nonwoven fibrous insulation product has at least a bi-modal fiber diameter distribution designed to provide the product with selected thermal insulating and physical performance properties that are affected by fiber diameter such as rigidity and recovery properties. The product is made by: forming two or more fiber groupings that each have a selected fiber diameter distribution with a selected mean fiber diameter wherein the selected fiber diameter distributions of the fiber groupings differ from each other. The fibers of the fiber groupings are intermingled and entangled together in selected percentages by weight to form a product with a selected density and thickness that exhibits selected product performance properties based on the properties of the fiber groupings and the relative percentages by weight of the fiber groupings.

Disclosed herein is the preparation of woven fabrics suitable for use in manufacturing vehicle airbags. Such fabrics are woven from a plurality of polymeric, e.g., polyamide, warp and weft tapes which have preferably been slitted, preferably in the machine direction, from a thermoplastic polymer film, and preferably from such a film which has been drawn at least in the machine direction. The resulting fabrics exhibit both the relatively low basis weight, stiffness and small packing volume typical of nylon films, and the relatively high tear strength and high damage tolerance of yarn-based woven airbag fabrics.

A gypsum product with a fortified glass fiber mat is provided in which the glass fiber mat is strengthened by crystallization of salt crystals on the glass fiber mat prior to the glass fiber mat use in the gypsum product. Methods for making a glass fiber mat saturated with salt crystals and gypsum products with the glass fiber mats are provided as well.

The present invention relates to a non-woven fabric made of inorganic fibers, which has a coating of at least two layers on one of both surfaces, wherein (i) the non-woven fabric made of inorganic fibers has a thickness of at least 0.2 mm, (ii) the first layer of the coating comprises particles, whose particle size is between 50 and 100 m, (iii) the second layer of the coating, which is applied onto the first layer, comprises particles, wherein more than 90% of the particles have a particle size of less than 20 m. The non-woven fabric made of inorganic fibers according to the invention, in particular glass non-woven fabrics, are in particular suitable for producing decorative coatings for floor coverings, ceiling coverings and wall coverings.

The carbon fiber forming raw material is a carbon fiber forming raw material (Z) as a prepreg including sizing agent-coated carbon fibers and a thermosetting resin or a carbon fiber forming raw material (Y) as a forming material that includes sizing agent-coated carbon fibers and has a woven fabric form or a braid form. The sizing agent includes components (A) and (B). The component (A) is an epoxy compound having two or more epoxy groups or two or more types of functional groups. The component (B) is one or more compounds selected from the group consisting of a tertiary amine compound, a tertiary amine salt, a quaternary ammonium salt, a quaternary phosphonium salt, and a phosphine compound. The component (B) is contained in an amount of 0.1 to 25 parts by mass relative to 100 parts by mass of the component (A).

The present invention relates to a textile web material having improved mechanical strength, in particular having resistance to piercing and/or shooting, having a protective function against chemical and/or biological toxins, in particular weapon agents. The textile web material according to the invention comprises a multilayer construction, wherein the layer construction comprises at least one layer resistant to piercing and/or shooting, and at least one adsorption layer based on discrete adsorption particles.
