A hybrid woven textile for reinforcing a polymer matrix of a composite material that includes inorganic fibers selected from glass fibers, basalt fibers, carbon fibers, ceramic fibers, quartz fibers and silica fibers, and natural organic fibers, characterized in that the inorganic fibers and the natural organic fibers are co-woven, co-braided or co-knitted with one another.

The purpose of the present invention is to provide a synthetic fiber which is for use in fabrics having uniform fiber density, permeability and the like, is appropriate for high-density, high-speed weaving, and exhibits excellent weft insertion stability. This synthetic fiber is characterized by having: a fiber density of 200-720 dtex; an average intermediate loading modulus of more than 75 cN/dtex and less than 150 cN/dtex; and a variation coefficient of the intermediate modulus of 5% or less.

An industrial fabric (30, 40, 45) is provided, in particular for transporting a nonwoven web while producing same, having a product side (PS), which is in contact with the nonwoven, and a machine side (MS), which is in contact with transport devices of a system (1) for producing the nonwoven. The fabric (30, 40, 45) has MD threads (32, 33, 43, 44, 48, 50), which run in the running direction of the nonwoven web, and CMD threads (31, 41, 42, 52), which run perpendicularly to the MD threads, said threads being woven together. At least two layers of MD threads (32, 33, 43, 44, 48, 50) are provided which are stacked one over the other in pairs and form product contact MD threads (32, 43, 50) and non-product contact MD threads (33, 44, 48). At least the material of each product contact MD thread (32, 43, 50) facing the product side (PS) forms a contact angle, measured according to the Wilhelmy plate method, of at least 80°, preferably at least 90°, more preferably at least 100°. In order to prevent the adhesion of threads to the fabric (30, 40, 45) and in order to reduce the air permeability, the fabric has a single layer of CMD threads (31, 41, 42, 52), and the cross-section of each product contact MD thread (32, 43, 50) has at least two regions, a first region of which is formed of the first material and a second region of which is formed of the second material. A substantial proportion, preferably a predominant proportion, of a tensile force acting on each product contact MD thread (32, 43, 50) can be transmitted from the second region, and the cross-section of the product contact MD threads (32, 43, 50) have a second region in the form of a core (61) and a first region in the form of a casing (62) which surrounds the core (61). The product MD threads (32, 43, 50) are preferably coextruded or are extruded in two successive steps. The MD threads (32, 33, 43, 44, 48, 50) have a flattened cross-section, preferably a rectangular cross-section, wherein a ratio of a height of the cross-section to a width of the cross-section preferably ranges from 1:1.2 to 1:10, preferably from 1:1.5 to 1:4. The invention further relates to a method for producing a nonwoven and to the use of an industrial fabric (30, 40, 45).

Disclosed are exemplary embodiments of woven filtration fabrics that include core-sheath spun yarns in either or both of the warp and weft directions.

A fiber structure can be used as a cell scaffold material, which fiber structure includes a multifilament formed by bundling monofilaments having an average fiber diameter of 1 to 15 μm, wherein each of the monofilaments satisfies Formula (1): (Y/X)×100>50 . . . (1) wherein, in Formula (1), X represents the number of monofilaments for which the average crossing angle is investigated, and Y represents the number of monofilaments having an average crossing angle of not more than 25° in X.

A moisture absorbent core sheath composite yarn has a sheath portion polymer that is a polyamide and a core portion that is a thermoplastic polymer, and has a moisture absorbance/desorbance (ΔMR) of 5.0%, wherein the ΔMR maintenance rate after 20 washes is 90%-100%. The core sheath composite fiber has high moisture absorbance, is more comfortable than natural fibers, and has wash resistance with moisture absorbance that stands up to real use and color fastness.

In a woven fabric woven from first constituent yarns as one of warps and wefts and second constituent yarns as the other, a part of the first constituent yarns are 2 to 15 side emission type optical fibers woven in juxtaposition, and, when the number of the side emission type optical fibers is 3 or more, a twist-preventing yarn having a dimeter smaller than that of the side emission type optical fibers is interposed between the one or two side emission type optical fibers and the one or two side emission type optical fibers.

A woven fabric includes a first constituent yarn having an optical fiber yarn and a non-light guiding yarn and a second constituent yarn having a non-light guiding yarn. The woven fabric has a first region in which the first and second constituent yarns are woven in one layer and a second region which is positioned adjacent to the first region and in which the first and second constituent yarns and are woven in two or more separable layers. The woven fabric has an optical fiber layer and a back protecting layer as the separable layers. The optical fiber layer is a layer formed of the optical fiber yarns. The back protecting layer is a layer in which the non-light guiding yarn of the first constituent yarn and the non-light guiding yarn of the second constituent yarn are woven. Further, the woven fabric can further comprise a front protecting layer.

Embodiments generally relate to devices and methods for production of fibers and threads for use in electronic device manufacturing. Described here, fibers can be produced and manipulated using a dual-surfaced sizing material. The dual-surfaced sizing material has a surface which binds a fiber and a surface which binds a resin. Thus, the dual-surfaced sizing material can be left attached to the fibers without adversely affecting the resin binding in later production steps.

A flexible second gas barrier for a liquefied gas storage tank which includes a stiffener fabric weaved with two or more kinds of fiber yarn selected from a group consisting of a glass fiber, a carbon fiber, an aramid fiber, and a synthetic fiber. The stiffener fabric is weaved so that a hybrid fiber yarn is made by 2-ply yarning two or more kinds of a single yarn or a twisted yarn of fiber yarn selected from a group consisting of a glass fiber, a carbon fiber, an aramid fiber, or a synthetic fiber, is included in the weft and/or warf so that repeated fatigue resistance, even under cryogenic conditions, is achieved, which ultimately has the effect of solving the problems associated with repeated load increase imposed on the second gas barrier as the thickness of LNGC Foam increases.
