Abstract:
The invention relates to a fabric for lightweight nautical sails, such as spinnakers, asymmetric spinnakers, and gennakers, for sailboats and other surface vessels, the fabric being formed of continuous polyester warp and weft yarns and being coated on one or both of its two surfaces with a crosslinked polymer, characterised in that the polyester is poly(ethylene terephthalate) (PET) having a tenacity greater than or equal to 6 cN/dtex; in that the fabric has a density of between 20 and 50 threads/cm, in terms of warp and weft density; in that the polymer is a crosslinked polyurethane (PU) that is polyether-, polyester-, or polycarbonate based; and in that this PU is derived from the crosslinking (1) of a single-component polyurethane elastomer having a modulus at 100% elongation comprised between 1 and 15 MPa, better still between 2 and 15 MPa, in particular between 6 and 15 MPa, according to the standard DIN 53504, used in implementation in solvent phase; and (2) by a crosslinking agent, based on a proportion of dry crosslinking agent relative to the dry elastomer of between 20% and 75% by weight, in particular between approximately 30% and approximately 75% by weight. The coated fabric has an elongation in the bias direction under 20 Lbs, comprised between 10 and 30 hundredths of an inch.
Abstract:
A yarn or thread may include a plurality of substantially aligned filaments, with at least ninety-five percent of a material of the filaments being a thermoplastic polymer material. Various woven textiles and knitted textiles may be formed from the yarn or thread. The woven textiles or knitted textiles may be thermal bonded to other elements to form seams. A strand that is at least partially formed from a thermoplastic polymer material may extend through the seam, and the strand may be thermal bonded at the seam. The woven textiles or knitted textiles may be shaped or molded, incorporated into products, and recycled to form other products.
Abstract:
A method of reducing crimp in woven sailcloth comprising applying heat to warp yarn or fill yarn prior to the yarns being woven into fabric and a method of making a sail comprising assembling panels of sailcloth comprising warp yarns and fill yarns, wherein at least one panel of sailcloth is prepared by applying heat to the warp yarn or the fill yarn prior to the yarns being weaved into fabric.
Abstract:
The present invention relates to a method and an apparatus for cleaning flat fabrics, especially sails for sailboats, in which at least one cleaning solution is applied to the flat fabric in a washing apparatus. According to the invention, it is provided that the flat fabric is moved forward continuously in its spread-out state through several cleaning stations arranged along a horizontal, planar conveyance track, without tumbling or serpentine back-and-forth bending.
Abstract:
A warp oriented woven sailcloth is provided in warp yarns are relatively uncrimped relative to the fill yarns. The yarn weight ratios (fill vs. warp) are 1.0 to 1 and 0.22 to 1.

Abstract:
A fibrous assembly includes two components. The first component provides a visual indication of when a pre-determined tensile load is applied to the assembly or when the fibres of the assembly have been over-extended. The first and second components are movable relative to each other, the visual indication being provided by the first component being substantially concealed by the second component and becoming at least partially exposed when the pre-determined tensile load is applied to the assembly or when the fibres have been over-extended. The first component comprises auxetic yarn.
