Definitions

  • This disclosure relates to combination yarns, and more particularly to polyester yarns and carpets using such yarns as pile yarn.
  • Carpets, rugs, and mats used in home or commercial applications are typically made from natural fibers (such as cotton or wool) or synthetic fibers (such as nylon, polyester, polyolefins, acrylics, rayon, and cellulose acetate). Synthetic fibers tend to be more favored in carpet manufacture as they are generally more commercially acceptable and can be used for a wider variety of applications.
  • Nylon is often used in carpet fiber since it is strong, easy to dye, and readily available. Nylon carpeting can be disadvantageous, however, as it generally requires various treatments due to its susceptibility to developing static electric charges and its ease of staining. Carpets made from polyolefins, such as polypropylene, are very resistant to staining and are naturally antistatic; however, polypropylene is a more rigid and less resilient fiber and will not generally maintain its appearance or shape under prolonged or heavy use, or after repeated deformations.
  • Polyesters such a PET, PTT, and PBT are a favorable alternative to both nylon and polyolefins and are known to provide stain resistance and static resistance while also providing a "wool-like" feel with good physical performance.
  • WO 2012/012597 A2 relates to polyester yarns made from two or more different polyesters.
  • the invention is also directed to finished articles made from two or more different polyesters, and especially to carpets.
  • JP 2005 023495 A provides a doubled and twisted yarn for forming a carpet that has both aesthetic appearance of the pencil point-like pattern and high cushioning properties with soft feeling and compression recovery, light resistance, antifouling properties, and provide the carpet by using the doubled and twisted yarn.
  • the present disclosure provides combination yarns, in particular combination yarns formed from two or more polyester yarns having different polymeric compositions yet having substantially the same color strength when dyed under the same dyeing conditions, for example when both yarns are dyed together.
  • the present disclosure provides combinations yarns formed from two or more polyester yarns having different polymeric compositions that provide substantially different color strength between the two yarns when dyed under the same dyeing conditions, for example when both yarns are dyed together.
