Abstract:
Flame resistant fabrics are formed by warp and fill yarns having different fiber contents. The fabrics are constructed, for example, by selection of a suitable weaving pattern, such that the body side of the fabric and the face side of the fabric have different properties. The fabrics described herein can be printable and dyeable on both sides of the fabric and are suitable for use in military and industrial garments. Methods of forming flame resistant fabrics, and methods for forming garments from the fabrics, are also described.

Abstract:
Bi-directional and multi-axial fabrics, fabric composites, ballistically resistant assemblies thereof, and the methods by which they are made. The fabrics are comprised of sets of strong, substantially parallel, unidirectional yarns lying in parallel planes, one above the other, with the direction of the yarns in a given plane rotated at an angle to the direction of the yarns in adjacent planes; and one or more sets of yarns having lower strength and higher elongation interleaved with the strong yarns. The fabrics of the invention provide superior ballistic effectiveness compared to ordinary woven and knitted fabrics but retain the ease of manufacture on conventional looms and knitting machines.
Abstract:
Disclosed is a polyethylene glycol modified copolyester fiber that has exceptional moisture management characteristics and that can be formed into exceptionally comfortable fabrics. The copolyester fiber includes polyetylene terephthalate in an amount sufficient for the copolyester fiber to possess dimensional stability properties substantially similar to those of conventional, unmodified polyethylene terephthalate fibers, polyethylene glycol in an amount sufficient for the copolyester fiber to possess wicking properties that are superior to those of conventional, unmodified polyethylene terephthalate fibers, and chain branching agent in an amount less than about 0.0014 mole-equivalent branches per mole of standardized polymer.
Abstract:
A spun yarn characterized by comprising at least 15 wt.% short fibers of polytrimethylene terephthalate and satisfying the relationship: modulus at 5% elongation (%) >/= 0.1X + 70 wherein X represents the content (wt.%) of the short polytrimethylene terephthalate fibers in the spun yarn. It is excellent in suitability for knitting/weaving, stretchability, and recovery from stretch and has shape stability and durability in long-term wear.
Abstract:
The invention relates to a polymer composition, comprising a biologically degradable polymer and a material from marine plants and/or marine animal shells, or at least two components chosen from the group comprising, saccharides and derivatives thereof, proteins, amino acids, vitamins and metal ions. The invention further relates to a moulded body, made from said polymer composition. Said moulded body may be used as packing material or fibre material. In the form of a fibre material said body may be used as a mixture component for the production of yarns, non-woven fabrics or textiles.
Abstract:
Disclosed is a method of copolymerizing polyethylene glycol (PEG) into polyethylene terephthalate (PET) to achieve a polyethylene glycol-modified polyester composition that can be spun into filaments. The method includes the steps of copolymerizing polyethylene glycol into polyethylene terephthalate in the melt phase to form a copolyester composition, then polymerizing the copolyester composition in the solid phase until the copolyester is capable of achieving a melt viscosity that facilitates the spinning of filaments, and thereafter spinning filaments from the copolyester. A copolyester composition comprised of polyethylene glycol and polyethylene terephthalate is also disclosed. Fabrics made from fibers formed from the copolyester composition possess wetting, wicking, draying, flame-retardancy, static-dissipation, and soft hand properties that are superior to those of fabrics formed from conventional poylethylene terephthalate fibers of the same yarn and fabric construction.
