A drawing and spinning apparatus of mixed yarns for air spinning machines with multiple feeds comprises at least a first and a second introducer element, an air spinning device, a drawing device, interposed between the introducer elements and the air spinning device, an air spinning chamber, an introducer nozzle shaped to receive the webs from the drawing device into respective insertion channels and introduce the webs into the spinning chamber according to a longitudinal feeding direction. With respect to a cross-section plane perpendicular to the longitudinal feed direction, groove bottoms of each of the two insertion channels of the webs into the chamber are aligned along a segment which is offset by an eccentricity with respect to a geometric centre of the chamber itself, through which a symmetry axis of the spinning chamber passes, the eccentricity being less than 5% of a maximum diameter of the spinning chamber.

A method includes forming a multi-pick yarn package through winding multiple oriented yarns onto a spool, with the multiple oriented yarns serving as weft yarns forming adjacent substantially parallel yarns wound together. Each of the multiple oriented yarns is formed through drawing each of multiple yarns from a corresponding supply package. The method also includes, using the multi-pick yarn package, simultaneously inserting the weft yarns in a single pick insertion event of a pick insertion apparatus of a loom apparatus in which the simultaneously inserted weft yarns are to be conveyed through a set of warp yarns to produce an incremental length of a woven textile fabric.

A textile jet subassembly includes a textile jet or jet nozzle mounted on a base support. An upper impact plate and a lower insert plate form the yarn channel passing through the jet or jet nozzle. A jet interface and a threading slot communicate with the yarn channel and the sidewalls above and below the threading slot are coplanar to form a smooth surface. Multiple alignment or registration recesses and cooperating pin fasteners are spaced from the yarn channel on the same side of the yarn channel to properly align the side walls above and below the threading slot.

An air textured yarn (ATY) is disclosed. The ATY includes a first filament having a first cross section, and a second filament disposed adjacent to the first filament having a second cross section, wherein the first cross section has a substantially circular shape and has a degree of modification (M ratio) less than or substantially equal to 1.3, the second cross section has a polygonal shape including 3 to 6 lobes, and a difference between a length of the first filament and a length of the second filament is less than or substantially equal to 4%. Further, a method of manufacturing the ATY is also disclosed.

Processes are provided for the manufacture of color effect face yarns for use in tufted goods. These color effect yarns may exhibit unique color effects and contain a lower overall denier, thereby allowing the production of tufted goods with a greater than normal tuft density per unit area. Consequently, this can result in finer color effects and/or sharper definition of color effects in the tufted goods and expands the design possibilities for such products.

A task is to provide a cloth and a fiber product, which exhibit not only stretchability but also novel appearance and novel hand due to ununiformity of the appearance and hand, and the task is achieved by forming a cloth with a crimped fiber containing two or more types of single fibers which are different from each other, and having a torque of 30 T/m or less.
