Definitions

  • the present invention relates to fibers, yarns and fabrics in the arena of technical wear, athletic wear or“athleisure” wear.
  • Cotton is an extremely comfortable fiber in many circumstances and cotton garments remain ubiquitous based on their light weight, versatility, and favorable hand.
  • the term“hand” is used throughout this application in the sense that is well understood to the skilled person. It can be defined as,“a characteristic of fabrics that is perceived by touching, squeezing, or rubbing them” (Tortora at page 262), or as,“the “term used to describe the feel of a substrate (i.e., soft, raspy, stiff, etc.)” (Textile Glossary; Cotton Incorporated; www.cottoninc.com; accessed March 15, 2018.
  • cotton has certain disadvantages.
  • Cotton is highly absorbent, taking up to 27 times its weight in water, which adds undesired weight in the athletic wear context.
  • Cotton also loses its insulating properties and can be abrasive when wet.
  • active exercise or work, etc.
  • Cotton layers next to the skin quickly become wet, heavy, and cold.
  • Cotton undergarments become abrasive when wet in both hot and cold weather.
  • Wool has excellent insulating properties, can stretch as much as 30% beyond its relaxed length, and can absorb moisture in up to 50% of its dry weight without becoming saturated, Tortora, FAIRCHILD’S DICTIONARY OF TEXTILES, 7th Ed. (2009), page
  • Some types of wool are, however, uncomfortable next to the skin, and the more comfortable fibers (e.g., merino) tend to be more expensive.
  • Silk is, of course, extremely comfortable, but in general too expensive for widespread use in mass-marketed athletic garments.
  • moisture management is used to describe the capacity or ability of a fabric to pull or wick moisture (perspiration, humidity, rain) to an outer layer of a fabric from which it can evaporate.
  • body temperature 98.6°F, 37°
  • Moisture management is thus typically measured using water vapor transmission rate.
  • Synthetics are not an automatic cure-all, however, because overcooling can give a clammy feel to the wearer. Accordingly, modern“technical” wear often consists of two types of yarn formed into several layers that are arranged so that thermodynamics drives perspiration from the skin to the first layer and then from the first layer to the outer layer. Modern technical fabrics may have as many as four or five layers for this purpose.
  • the starting fibers help establish the properties of the resulting fabric
  • the skilled person recognizes that with respect to (for example) cotton, shorter fibers produce yarns that in turn give fabrics with a better hand, while longer fibers give smoother more finished yarns, such as those that give a cotton business shirt (again, as just one example) a more finished look, but a rougher hand.
  • the invention is a yarn consisting essentially of a blend of polyester fibers customized by three parameters: (1) a combination of polyester staple fibers with staple lengths of 1.5 inches, 1.25 inches, 1.0 inch and 0.75 inch; (2) a combination of polyester staple fibers with staple deniers (tex, fineness) of 1.0 dpf, 1.2 dpf, and 1.5 dpf; and (3) a combination of polyester staple fibers with at least two different staple cross sections.
  • the invention is an intimately blended bale of polyester staple fibers in which the blend includes (1) a combination of staple fibers with staple lengths of 1.5 inches, 1.25 inches, 1.0 inch and0.75 inch; (2) a combination of staple fibers with staple deniers (tex, fineness) of 1 .0 dpf, 1 .2 dpf, and 1 .5 dpf; and (3) a combination of staple fibers with at least two different staple cross sections.
  • the invention is a fabric that includes at least some yarns that consist essentially of (1) a combination of polyester staple fibers with staple lengths of 1 .5 inches, 1 .25 inches, 1 .0 inch and 0.75 inch, (2) a combination of polyester staple fibers with staple deniers (tex, fineness) of 1 .0 dpf, 1 .2 dpf, and 1 .5 dpf; and (3) a combination of polyester staple fibers with at least two different staple cross sections.
  • the invention is a resulting fabric according to selected from the group consisting of woven fabrics, nonwoven fabrics, and knitted fabrics.
  • the invention is a method of making a yarn precursor blend with selected properties of moisture management and hand that includes the steps of spinning continuous synthetic filament in each of at least three different deniers and at least two different cross sections, gathering the different continuous filaments into a single tow, using a common cutter to cut the tow into it at least four different staple lengths, and blending the different length, different denier and different cross-sectional staple fibers into an intimately blended bale.

  • the invention is a reel assembly for use with a staple cutting apparatus that includes a cutter reel having a pair of annular reel members spaced axially one from the other with each reel member defining an outwardly facing axial surface having a predetermined diameter and a circumferential mating engagement portion; a plurality of cutter blades mounted in said reel members for engaging and cutting fiber; and a cover member encircling and affixed about one of the reel members; in which the improvement comprising cutter blades spaced to cut synthetic filament into discrete staple lengths of 1.5 inches, 1.25 inches, 1.0 inch and 0.75 inch.

  • polyester refers to any polymer formed by joining hydrocarbon chains with ester groups (Tortora, page 437).
  • the US Federal Trade Commission defines polyester as,“[A] manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 85% by weight of an ester of a substituted aromatic carboxylic acid, including but not restricted to substituted terephthalate units.” 16 C.F.R. ⁇ 303.7(c)(2018).
  • Bale Density A unit of measurement of weight per unit volume normally expressed as pounds per cubic foot. Density is calculated by dividing the net bale weight by the bale volume in cubic feet. Volume is determined by multiplying bale length, width and thickness dimensions expressed in feet. Thickness is determined by measuring from tie to tie across the crown of the bale.

  • Gin UD Bale compressed at the gin to a density of at least 28 pounds per cubic foot.
  • Gin SD Bale compressed at the gin to a density of at least 23 pounds per cubic foot but less than 28 pounds per cubic foot.
  • “spinning” has two distinct meanings. In a classical meaning dating almost to antiquity,“spinning” refers to the step of twisting fibers together to make yarns. In modern technology this is (typically) carried out using“ring” spinning or“open end” spinning, each of which are Familiar to the person of ordinary skill in the art; e.g. Tortora, Fairchilds Dictionary Of Textiles, 7th Ed. (2009) at pages 473 and 395.
  • the word“spinning” is used to refer to the step of extruding a polymer melt into individual filaments which are then processed further, typically including texturing, cutting into“staple” lengths, and spinning the polymer staple fibers into yarns in the open end or ring spinning sense.

  • the yarn includes 94% by weight of fibers at least 100 mtex; 87% by weight of fibers of at least 125 mtex; 76% by weight of fibers having at least 150 mtex: and 63% of fibers having at least 175 mtex; with all percentages expressed to 2 significant figures.

  • the common cutter allows feeding and opening from one bale as opposed to drawing from multiple bales, each of which would have one of the separate characteristics. As known to those of skill in the art, the sooner different fibers are blended (i.e., earlier in the spinning process; baling, opening, drafting, etc.), the more consistent will be the characteristics for which the yarn was blended.
  • the invention is an intimately blended bale of polyester staple fibers that includes the combination of staple fibers with staple lengths of 1.5 inches, 1.25 inches, 1.0 inch and0.75 inch; the combination of staple fibers with staple deniers (tex, fineness) of 1.0 dpf, 1.2 dpf, and 1.5 dpf; and the combination of staple fibers with at least two different staple cross sections. It follows that an opened bale of this type, and a yarn spun from this bale share the length, denier and cross-sectional characteristics of the intimately blended bale.
  • the intimately blended bale allows adjustment within a single bale and avoids the necessity to carefully meter fibers from multiple bales of different characteristics.
