  • Publication number: 20170233901
    Abstract: A hybrid yarn and a fabric including the hybrid yarn are provided. The hybrid yarn is formed of a plurality of fibers of a plurality of different fiber compositions. The different fiber compositions are interspersed throughout the yarn. The yarn may be formed using fibers made of the same material or a plurality of different materials. The different fiber compositions may include fibers of three or more different cross sections, fibers made of different materials or a combination of the two. The materials may be synthetic and/or natural materials. The yarn may be constructed to impart selectable functional characteristics to a fabric without the need to include chemicals to impart those characteristics. Fabrics made with the hybrid yarn will have selectable functional features and also be of lighter weight than previously possible. Hybrid spinnerets may be used to produce hybrid yarns with three or more different fiber cross sections.

  • Patent number: 9121642
    Abstract: A fabric for thermal management including the cooling of an object, such as a person's skin. The fabric is formed of a plurality of materials including at least one liquid transport enhancing material and at least one evaporative transport impeding material. When the fabric is in use, the transport enhancing material is located near an object to be cooled, while the evaporation impeding material is spaced away from the object. The fabric is peached so that there is an entanglement of the two materials. Peaching is performed on both sides of the fabric, but initially on the side with the transport enhancing material such that a portion of the evaporation impeding material is pulled into the fabric core. A method of making the fabric is also described.
