    Abstract: Fabric structures having two connection segments and an expansion segment between the two connection segments are provided. The fabric structure includes ground yarns that form a sheath, binder yarns, elongation yarns surrounded by the sheath, and lateral yarns. In the expansion segment, at least some of the lateral yarns are interwoven with the elongation yarns to connect the elongation yarns laterally with the sheath. Heat treatment of the expansion segment shrinks the length of the elongation yarns during manufacture. The sheath does not substantially shrink from the heat treatment relative to the elongation yarns and gathers together in an accordion-like arrangement. A tensile load applied to the fabric structure stretches the elongation yarns and unfolds the gathered sheath. The high strength sheath supports the tensile load when completely unfolded, while the elongation yarns absorbs energy as the fabric structure stretches or elongates.

When such textiles are applied to apparels like underwears, sweaters or jackets, the ultrafine fibers in the inner layer can completely absorb excessive water molecules on skin surface. When these water molecules that carry body heat pass through the middle layer, through the dual functions of the metal yarns of thermal insulation and the ultrafine fibers of moisture absorbance and sweat repellency, the water molecules are completely absorbed by the outer layer of pure cotton and repelled from the body. The body heat is conserved between the middle layer and human body.

  • Patent number: 7151062
    Abstract: A textile made at least in part with conductive yarns for the purpose of generating heat from an electrical power source. The textile has conducting yarns, or “heaters”, with conductivity and spacing tailored to the electrical source to be used and the heat to be generated. The heater yarns have a positive temperature coefficient whereby the resistance of the yarn increases with an increase in temperature and decreases with a decrease in temperature. “Leads”, such as conductive yarns, can be used to supply electricity to the heater yarns. A coating to the textile can electrically insulate the textile as well as provide protection to the textile during activities such as laundering or use.

  • Patent number: 7135227
    Abstract: Provided is an electrically conductive elastic composite yarn having an elastic member that is surrounded by at least one conductive covering filament. The conductive covering filament has a length that is greater than the drafted length of the elastic member such that substantially all of an elongating stress imposed on the composite yarn is carried by the elastic member. The elastic composite yarn may further include an optional stress-bearing member surrounding the elastic member and the conductive covering filament.

  • Patent number: 7115311
    Abstract: This invention relates to ungrounded type flexible fabric container with a reduced energy of electrostatic discharge suitable for use in a combustible environment. A woven fabric is configured to form a flexible fabric container having sidewalls, a top feature and a bottom feature. The woven fabric flexible bulk container is made from a static dissipating fabric comprising fabric woven of non-conductive tapes, to which a plurality of bicomponent conductive staple fibers are added. The bicomponent conductive staple fibers have one or more longitudinal stripes of a carbon loaded conductive constituent on an outer surface of a non-conductive constituent. Preferably the staple fibers are woven into or coated onto the fabric at a spacing of from 3 mm to 100 mm.

  • Patent number: 7001554
    Abstract: A durable erosion control blanket featuring a novel synthetic fiber filler is disclosed. The erosion control blanket of the present invention addresses the need for a particularly resilient erosion control blanket through the use of a post-consumer, crimped, polyester fiber filler material. In one embodiment, the post-consumer fiber material is of polyethylene terephthalate (PET) readily available in post-consumer form from the recycling of soda bottles. In short, a preferred filler material for the blanket of the present invention would utilize recycled soda bottle material which has been converted into a crimped, highly-resilient fibrous filler. It is, thus, possible to achieve the desired physical and mechanical properties in the erosion control blanket of the present invention while conserving natural resources to some extent by using a readily available post-consumer polymer material.
