  • Patent number: 6582818
    Abstract: The invention relates to fibers, particularly binder fibers, made from polyesters and the polyesters themselves. The polyesters are the product of a reaction between a glycol component and a dicarboxylic acid component where the glycol component contains at least 50 mole % of a four carbon diol, such as 1,4-butanediol, or a six carbon diol, such as 1,6-hexanediol or a mixture of a four carbon and six carbon diol. Typically, the polyesters of the invention are semicrystalline and/or crystalline and have a specific melting point ranging from about 140 to about 185° C. The polyesters of the invention may be formed into a variety of products, especially binder fibers for nonwoven fabrics, textile/industrial yarns and fabrics, composites and other molded articles.

  • Patent number: 5519066
    Abstract: Disclosed are branched polyester compositions having an I.V. of at least about 0.7 dl/g and a melt viscosity sufficiently high to permit foaming during extrusion or molding operations. These branched polyesters are readily foamable with a wide range of foaming agents to provide low density shaped articles, films, and sheets. The branched polyesters comprise about 80 to about 99.9 wt % of a polyester and about 0.1 to about 20 wt % of an ethylene copolymer containing repeat units of ethylene and of a monomer selected from the group comprising acrylic acid, methacrylic acid, alkyl acrylate, alkyl methacrylate and vinyl alcohol.
