The present invention relates to methods, apparatuses, and systems for controlling the density of a fluid near a functional object in order to improve one or more relevant performance metrics. In certain embodiments, the present invention relates to forming a low density region near the object utilizing a directed energy deposition device to deposit energy along one or more paths in the fluid. In certain embodiments, the present invention relates to synchronizing energy deposition with one or more parameters impacting the functional performance of the object.

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.

There are provided a towel cloth for which gluing is unnecessary during weaving and a method of producing the same. The towel cloth is composed of warp pile yarns, warp ground yarns, and weft ground yarns, warp pile yarns 1 are core-sheath conjugate spun yarns (bundled spun yarns), core component fibers 2 are polyester multifilament yarns, sheath component fibers 5 are cotton fibers, the sheath component fibers 5 include untwisted fibers 3 and wrapped fibers 4 on the surface thereof, and the wrapped fibers 4 are wound in one direction to bundle all components. The warp pile yarns 1 have a tenacious yarn structure, are strong against squeezing, and can be formed into a towel cloth without glue. This towel cloth is resistant to fluff dropping and has favorable water absorption and texture, and also has a fast drying speed.

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 thread count of a woven textile is proliferated by simultaneous insertion within a single pick insertion event of a loom apparatus multiple adjacent parallel yarns drawn from a multi-pick yarn package. In one or more embodiments, multiple texturized polyester weft yarns of denier between 15 and 65 are wound on a single bobbin in a parallel adjacent fashion such that they may be fed into an air jet pick insertion apparatus and/or a rapier pick insertion apparatus of an air jet loom to weave a textile that has between 90 to 235 ends per inch cotton warp yarns and between 100 and 965 polyester weft yarns.
