  • Publication number: 20140134908
    Abstract: The present invention provides, at a low cost, a suede-like flame-retardant union fabric which exhibits excellent design and texture, which is comfortable, and which has high flame retardance. The suede-like flame-retardant union fabric is formed of warps and wefts, in which the warps are raised on at least one face of the fabric. In the suede-like flame-retardant union fabric, the warps include a polyester-based yarn, and the wefts include a spun yarn (A) that contains at least 70 wt % of a cellulosic fiber and a spun yarn (B) that contains a flame retardant-containing halogen-containing fiber containing 3 to 50 weight parts of a flame retardant with respect to 100 weight parts of halogen-containing fibers. The spun yarn (A) and the spun yarn (B) used as the wefts are alternately interweaved.

  • Patent number: 7759266
    Abstract: A conveyor belt reinforcing fabric weave is disclosed, having a plurality of center tension warps crimped about a plurality of middle wefts. Upper and lower wefts lie above and below the middle wefts. The upper and lower wefts are in opposition to each other and in non-opposition with the center wefts. Binder warps are interlaced above and below the central tension warps in alternating sequence, with at least one of the binder warps interlacing upper and lower wefts other than those interlaced by an adjacent binder warp. Interlacing of the middle wefts by the central tension warps locks the wefts in place, providing enhanced resistance to faster pullout. The lack of straight tension warps provides a highly flexible fabric that can be used in multi-ply applications. A conveyor belt incorporating one or more plies of the inventive fabric is disclosed, as is a method for manufacturing the belt.

    Abstract: An improved load leveling yarn has a force-displacement profile that maintains desirable properties of previously known yarns (as exemplified in U.S. Pat. No. 5,830,811), but exhibits a lower elongation at a stress that is greater than the IBS but less than or equal to 1.8 grams/denier. Especially preferred yarns are produced from PET with an IV of greater than 0.9 and epsilon caprolactone (at a ratio of about 90:10) under copolymerization conditions that allow reaction of at least 95% of the added epsilon caprolactone. Such yarns can then be formed into a web to form specific products, and especially seat belts.

    Abstract: The present invention relates generally to substrates that exhibit useful, auto adaptable surface energy properties that depend on the environment of the substrate. Such surface energy properties provide relatively high advancing and receding contact angles for liquids when in contact with the target substrate surface. The substrates exhibit low surface energy quantities of at most about 20 millijoules per square meter (mJ/m2) at a temperature of about 25 degrees C. and a surface energy greater than about 20 mJ/m2 at, or with exposure to, a temperature of about 40 degrees C. More specifically, encompassed within the present invention are textile substrates having this highly desirable unique surface energy modification property and which exhibit wash durable oil and water repellency and stain release features. Novel compositions and formulations that impart such surface energy modifications to substrates are also encompassed within this invention, as well as methods for producing such treated substrates.

  • Patent number: 6713412
    Abstract: Specific fabric articles exhibiting very low air and/or gas permeability (even upon application of high inflation pressures) and very high tear strengths are herein disclosed and claimed. Such a specific fabric also permits the incorporation of discrete openings (through cutting, for example) through which air and/or gas introduced by an airbag inflation canister will travel. Such a specific fabric acts as a barrier to the complete introduction of high pressure inflation gases into an airbag cushion, thereby permitting a more controlled, safer inflation upon the occurrence of a collision event. Thus, the specific inventive fabric permits movement of inflation gas and/or air substantially solely through the openings within the fabric and not through the interstices between the individual fiber constituents.

    Abstract: A single layer woven fabric for paper-making, in which at least a pair of two successive knuckles in the paper-making side at an interval of one warp, and at least one crimp in the running side form a plain weave structure. The knuckle be formed by allowing a weft to pass over one warp, to pass under one adjacent warp, and then to pass over the one warp. The crimp be formed by allowing a weft to pass under not less than three successive warps. The plain weave structure is formed by binding two or three wefts constituting a group which in turn constitutes a repeating unit and by placing the combined group, in the direction of wefts, so that the knuckles of wefts in the paper-making side are placed successively at an interval of one warp. The placement of the wefts group is made by shifting the group as the whole successively by a distance corresponding to an odd number of the warp.
