TEXTILE MATERIALS CONTAINING DYED POLYPHENYLENE SULFIDE FIBERS AND METHODS FOR PRODUCING THE SAME
A textile material comprises a plurality of yarns, the yarns containing an intimate blend of dyed polyphenylene sulfide fibers and cellulosic fibers. The dyed polyphenylene sulfide fibers comprising a disperse dye that is distributed substantially evenly across the cross-sectional area of the fibers. A method for dyeing textile materials containing polyphenylene sulfide fibers comprises the steps of (a) providing a textile material comprising yarns which contain an intimate blend of polyphenylene sulfide fibers and cellulosic fibers, (b) providing a dye liquor comprising a liquid medium and a disperse dye, (c) applying the dye liquor to the textile material, (d) heating the textile material under ambient atmosphere to a temperature sufficient to evaporate substantially all of the liquid medium from the textile material, and (e) heating the textile material under ambient atmosphere to a temperature of about 180? C. or more to fix the disperse dye to the polyphenylene sulfide fibers.
WEARABLE PROTECTIVE DENIM FABRICS
Provided herein are blended fibers for use in protective clothing which confer protection against electrical arcs and/or flash fire hazards and also have a pleasing appearance, while also being comfortable to wear. The fabrics described herein can be processed to give an aesthetically desired appearance such as a washed denim look.
Unitary woven fabric construct of multiple zones
A fabric construct consists of a woven fabric of weft and warp yarns, and the fabric has an area defined by plurality of zones consisting of at least one zone of a first zone type, optionally, at least one zone of a second zone type; and at least one zone of a third zone type. The third zone is a transition zone disposed adjacent the first and/or second zones. All the zones are formed in a unitary woven construct, with adjacent zones seamlessly joined together. The transition zone includes a plurality of bands of sets of weft and/or warp yarns that collectively provide a progressive transition for an attribute of the first zone type through at least the transition zone and to the second zone type, if present. The fabric construct may be used in various end products and is particularly suited for use in apparel applications.
PRODUCTION PROCESSES OF POLYESTER FILAMENTS FOR MOISTURE WICKING
The process of the present invention may be used to produce polyester filaments that exhibit superior moisture and perspiration absorption. In various embodiments, this process involves: (1) pre-crystallizing polyester chips in a crystallizer; (2) drying and ventilating the polyester chips after crystallization to produce dried polyester chips; (3) melting the dried polyester chips in a screw extruder; (4) filter the melted polyester chips to form a filtered melt; (5) introducing the filtered melt into a spinning box via a metering pump, wherein the filtered melt enters the spinning assembly; (6) extruding the filaments from the spinning assembly; (7) cooling the extruded filaments from the spinning assembly to room temperature in order to solidify the filaments and form a fiber tow; and (8) winding the fiber tow via a winding machine to form a wound tow. The process described herein can produce polyester filaments that comprise a longitudinal groove along the surface of fiber, which can provide a capillary effect that enhances the moisture wicking capabilities of the filaments. Consequently, the polyester filaments of the present invention can be used to produce woven articles, such as reinforcement fabrics, that comprise fiber micro-grooves along the surface of the article, thereby enhancing the article's sweat wicking capabilities, water diffusion capabilities, and water transfer capabilities. Furthermore, the use of these grooved polyester filaments of the present invention can facilitate the migration of water and moisture to the surface of the fabric, thereby allowing the moisture to spread out on the surface and enabling it to quickly evaporate. Consequently, this can keep the skin of the wearer dry.
Ceramic matrix composite materials with rare earth phosphate fibers and methods for preparing the same
Disclosed is a ceramic matrix composite (CMC) material including rare earth phosphate ceramic fibers embedded in a ceramic matrix, wherein the ceramic matrix also optionally includes a rare earth phosphate material. Methods for manufacturing the CMC material and gas turbine engine components formed of the CMC material are also disclosed.
Flame Resistant Fabrics Having Improved Resistance to Surface Abrasion or Pilling and Methods for Making Them
Flame resistant fabrics and garments that have improved resistance to pilling and/or abrasion are disclosed. The fabrics, the fibers or yarns that make up the fabrics, or garments made from the fabrics are treated with a finish composition that is applied to the fibers, yarns, fabrics, or garments and then cured. The finish composition increases the resistance to pilling and/or abrasion of the fibers, yarns, fabrics, or garments. The finish composition includes a polymeric abrasion resistance aid, an alkylfluoropolymer, a polyethylene, and a wetting agent.
FLEXIBLE TRANSLUCENT TO TRANSPARENT FIREPROOF COMPOSITE MATERIAL
A fireproof, translucent, flexible coated fabric composite material for use in fire curtains. The composite material meets or exceeds regulatory requirements in terms of fire endurance and allows transmissivity of necessary amounts of light. The process of the present disclosure combines a silica fabric with a special refractory index controlled resin. This unique combination of materials can transform an opaque high temperature fabric into a translucent, and even transparent, composite which as the ability to resist high temperature, flame and smoke penetration that fills a needed gap in technology between visibility and fire resistance in the field of fire and smoke curtains used in civil construction.
Lightweight, dual hazard fabrics
Lightweight fabrics with a balance of high thermal properties, especially arc resistance and flash fire resistance, on the one hand, and durability and comfort properties, on the other hand, are disclosed. Articles, such as garments and linen, made from the lightweight fabrics are also disclosed. Spun yarns made with an intimate blend of fibers including flame resistant fiber, fire-resistant hydrophilic fibers, and a low level of anti-static fibers are described. The lightweight fabrics are particularly useful in garments for utility workers, industrial workers, military personnel, and firefighters.
CORE-SPUN YARN FEATURING A BLENDED CORE FOR USE IN THE CONSTRUCTION OF FLAME BARRIER FABRICS AND FINISHED ARTICLES MADE THEREFROM
A fire resistant core-spun yarn that comprises a unitary core having a blend of a filament fiber and non-filament fibers, and a sheath containing one or more staple fibers that substantially encapsulates the unitary core; and flame barrier substrates and articles made therefrom.
