Definitions

  • This invention relates to an elastic yarn structure with substantial hollow structure.
  • the core is composed of dissolvable part (dissolvable core) and elastic part (main elastic core) covered with single or multiple slivers, as well as fabrics containing such yarns and garments made use of such fabric.
  • the invention is particularly concerned with improvements of core-spun elastic yarns performance, recovery of stretch fabric and easier recycle of such woven fabrics, and comfortableness of stretch garments.
  • stretch woven fabric construction Due to pulling force of elastane, stretch woven fabric construction is more compact compared with rigid (without stretch) woven fabric and lead to low breathability. Wearing bad ventilation of garments made with stretch woven fabric is not good to health as bacteria growth faster because of humidity and warmness, those feeling is not good wearing experience either. Therefore, stretch woven fabric with good ventilation and less see through is still sought.
  • Stretch woven fabric made with hollow stretch yarns because of the loose yarn construction carried, has higher breathability and softer hand those provided consumers more comfort wearing experience as well as less see through under same final yarn size and construction.
  • Hollow stretch yarn provides a tunnel space so the drafted elastane inside could almost freely rebound and achieve prompt recovery (shown as Figure 6 ) in garments after stretching
  • the stretch fabrics are required to recover after stretching.
  • Artificial yarns (polyester etc.) are commonly adopted to reduce frictions to obtain rapid recover.
  • the cloth produced keeps good shape while stretching.
  • the touch of the artificial yarn is not as skin friendly as the natural yarn or the cellulose yarn.
  • the dyeing and reflectivity of the artificial yarn is not able to compete with the natural yarn.
  • the air permeability of the fabric is also important besides the resilience, which is far from satisfactory.
  • the gap of the duel core spun yarn or other elastic fabric is small which lead to low air permeability and cause uncomfortable especially in places such as underarm because of the accumulated humidity.
  • the superfine yarns are adopted or the density of the yarns is reduced, either of which cause the possible transparent due to the reduced cover factor.
  • the present application is a substantial hollow stretch yarn construction with covering fibers (shown as Figure 4 ), substantial hollow structure in central and at least one core, fabric comprising such yarn and the garment made from such fabric.
  • the final yarn construction is achieved by removing dissoluble core of composite core and substantially hollow space formed in central of yarn (shown as Figure 5 ).
  • the invention also covers a woven fabric from the hollow yarn, as well as garment made from such fabric.
  • main stretch core and dissolvable core is fed in the central of yarn during spinning.
  • the drafting ratio of main stretch core is ranged 230% to 350% according to technical needs; regardless it is parallel (shown as Figure 1 ) placement way or ply yarn way (shown as Figure 2 ) or spun yarn core.
  • the dissolvable core is under certain tension and drafting is below 5% as normally dissolvable fibers elasticity is low.
  • This invention relates to main stretch core with hollow structure that comprise dissolvable core with water-soluble vinylon or rayon and polyurethane filament(s).
  • the invention also relates to stretch woven fabrics comprising such core spun (shown as Figure 3 ) yarn and the garments made from such fabric.
  • the fabrics are substantially almost free from core exposure, as the portion of dissoluble core would be removed by hot water or hot alkaline bath in consequential fabric or garment processes.
  • the final hollow structure of yarn provided free space (shown as Figure 6 ) for main stretch core moving and shrinking in core of yarn, thus stretch fabric's recovery is improved. Because of interfering of the thick core in yarn spinning stage and the high shrinking of stretch yarn of hollow stretch yarn, the final sheath of yarn is an imperfect tube shape and result tinny path in fabric.
  • the final tube like construction improved yarn-covering factor and more efficient in light reflection compared with stretch yarn with same final weight, less see-through is achieved. Also, the final tube like structure provided fabric with thicker body while without shoulder additional garment weight.
  • a dissolvable core comprises water-soluble vinylon fibers yarn or filament and/or viscose rayon fibers and/or filament and filament(s) of polyurethane.
  • the dissolvable core would be totally or partially removed by hot water bath for dissolvable vinylon or hot alkaline for viscose rayon during fabric finishing or garment washing process, wherein a hollow yarn structure to be formed.
  • dissoluble core and main stretch core There are multiple ways for placing of dissoluble core and main stretch core.
  • the application could be in (a) parallel form; (b) twisted form; (c) covered yarn form (shown as Figure 1, 2 and 3 ).
  • the total core occupied total yarn linear weight in the rage from about 10% to 40%.
  • the total yarn size can be ranged from about 4 to about 60 English cotton count.
  • the hollow stretch yarn may be used in either warp or weft direction or both to produce warp stretch or weft stretch or bi-stretch woven fabrics.
  • the woven fabric of the invention can be any type construction, included but not limited to plain weave, different types of twills, ribs, satins, dobby weaving, and jacquards.
