A reinforcing fiber bundle is a continuous reinforcing fiber bundle having a length of at least 1 m and is characterized by the number of monofilaments per unit width being at most 1,600/mm and the average number of fibers in the bundle being at most 1,000 in a region (I), and the drape level found in a region (II) being 120-240 mm. The continuous reinforcing fiber bundle has a length of at least 1 m and is characterized by the adhesion amount of a sizing agent (I) in the region (I) being 0.5-10% by weight and the drape level found in the region (II) being 120-240 mm. The continuous reinforcing fiber bundle has superior mechanical properties, formability into complex shapes, and continuous producibility.

A method includes drawing each of multiple partially oriented yarns from a corresponding supply package to form an oriented yarn, twisting and detwisting filaments within the oriented yarn to provide texture thereto, to provide a low stability interlacing during weaving, and to intermingle the filaments comprising the oriented yarn, and applying a uniform air pressure to the oriented yarn to provide a counter-twist. The method also includes forming a multi-pick yarn package based on winding all formed oriented yarns, which serve as weft yarns forming adjacent substantially parallel yarns wound together, onto a spool, simultaneously inserting the weft yarns in a single pick insertion event of a loom apparatus, conveying the weft yarns across a warp shed of the loom apparatus through a set of warp yarns, and interlacing the set of warp yarns and the conveyed weft yarns to produce an incremental length of a woven textile fabric.

A thread intermingling device for textile machines includes a nozzle oriented to intercept the path of the base threads, a corresponding compressed-air feed line and intercepting means to intercept the line. The base threads are led next to the nozzle and impinged by a jet of compressed air causing intermingling. A control unit controls the intercepting means for shutting down the feed to the nozzle instantaneously or with delay with respect to the device stop and for reactivating the feed of compressed air to the nozzle instantaneously or in advance with respect to the device restart, and for the feedback automatic reactivation depending on the detected speed or movement of base threads.

In a polyester multifilament, a core-component high-viscosity polyester and sheath-component low-viscosity polyester have been composited into a core-in-sheath, wherein the difference in intrinsic viscosity between the core component and the sheath component is 0.20 to 1.00, the total fineness is 4 to 30 dtex, the single-yarn fineness is 1.0 to 5.0 dtex; the breaking strength is 5.0 to 9.0 cN/dtex, the fracture elongation is 12 to 45%, the degree of interlacement is 2.0 to 15.0/m, and the number of filaments thereof is 3 to 15.

The present invention is directed to a composite elastic yarn, including a core section including an elastic core filament, and a sheath section including staple fibers surrounding the core section, wherein the elastic core filament has a low cohesion property in which the inter-filament cohesion thereof is within the range of 9 to 198 mg when measured according to the ASTM D3822 method, and is also directed to a fabric, and a method for manufacturing a composite elastic yarn. According to the present invention, it is possible to solve a puckering problem occurring on the surface of a denim fabric, thereby improving a touch sensation and the quality of a final product.
