The present invention relates to a manufacturing method of a unique textured yarn by upgrading the equipment and processing the modified single-material precursor, the textured yarn thereof, and the fabric made with the textured yarn thereof. According to the method, titanium dioxide is added into a precursor of PET pre-oriented yarn with single filament DPF<0.5 to form the first precursor. Then, the first precursor is fed into a flat conveying roller, and then into a differential roller, and then into an accelerating roller to form a dark and light double colored textured yarn with linen-like appearance and tone. Then, the dark and light double colored textured yarn is conveyed to a heater for heating and setting, and then conveyed to a false twisting machine for processing. Finally, it is conveyed to a nozzle for spraying.

A method of manufacturing multi-ply separable textured yarn, the method comprising, passing a multi-ply separable interlaced filament yarn through a texturizing unit to form a multi-ply separable draw textured yarn, wherein the multi-ply separable interlaced filament yarn is separable in to at least two separable interlaced filament yarn, wherein the interlacing of the filaments within each separable interlaced filament yarn is retained during further processing of the yarn to fabric and in the fabric.

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.

The present invention relates to a polyamide fiber with improved comfort management properties. The present invention also discloses a method for obtaining such fiber and articles made therefrom. The polyamide fiber is produced from a hygroscopic polyamide in a multilobal cross section profile. The hygroscopic polyamide fiber is produced preferably from polyamide 5.X, X being an integer from 4 to 16. Most preferably polyamide 5.6, which is a biobased polyamide obtained from pentamethylenediamine and is derived from sugar-based renewable feedstocks. The present invention thus discloses a polyamide fiber and articles made therefrom for sportswear and leisurewear applications, with improved water absorption, wicking and drying properties, wherein the sweat is transported away from the skin and is quickly dried, thereby reducing the wet sensation and chill during activity. The present invention provides freshness and comfort by maintaining a pleasant skin temperature and microclimate.

The polyester fiber is an abrasion-resistant polyester fiber comprising ethylene terephthalate as a main repeating unit, characterized by satisfying the following requirements: (1) the fineness being from 8 dtex to 200 dtex inclusive; (2) the single yarn fineness being from 1.0 dtex to 4.0 dtex inclusive; (3) the breaking strength being 3.5 cN/dtex or greater; (4) the breaking elongation being from 20% to 50% inclusive; and (5) the minimum differential Young's modulus being 20 cN/dtex or less in an elongation range of from 2% to 5% inclusive on a stress-strain curve of the fiber.

A method of manufacturing multi-ply separable textured yarn, the method comprising, passing a multi-ply separable interlaced filament yarn through a texturizing unit to form a multi-ply separable draw textured yarn, wherein the multi-ply separable interlaced filament yarn is separable in to at least two separable interlaced filament yarn, wherein the interlacing of the filaments within each separable interlaced filament yarn is retained during further processing of the yarn to fabric and in the fabric.

A yarn including a plurality of twists formed by twisting single fiber strand or multiple fiber strands; and fiber grooves, which are spaces formed between the twists, to provide three-dimensional growth spaces and migration paths for cells. Accordingly, a cell proliferation rate and cell viability may be enhanced by creating microenvironments suitable for migration, proliferation and differentiation of cultured cells. In addition, cell clusters having more uniform shapes may be easily implemented by forming the proliferation spaces and migration paths for the cultured cells as similar as possible to each other in each scaffold. Further, the cells cultured thereby can be cultured in a suitable shape and structure to be applied to an in vitro experimental model or transplanted into the body of an animal, and can be widely applied in various products used in a cell culture or tissue engineering field.
