Abstract:
The present invention relates to bicomponent polymer fibers, and to processes for forming those fibers. Bicomponent polymer fibers are described, having a core comprising a core polymer and a sheath comprising a sheath polymer, wherein the sheath polymer is a polyolefm having an Mw less than about 65,000 g/mol. The core polymer has an Mw at least about 20,000 g/mol greater than the Mw of the sheath polymer. Processes for forming bicomponent fibers are also described, comprising (i) forming a molten blend of a core polymer and a sheath polymer; (ii) extruding the molten polymer blend using an extrusion die having a length to diameter ratio greater than or equal to about 10 and under shear conditions sufficient to drive the sheath polymer to the die wall; and (iii) forming meltblown fibers having a core comprising the core polymer and a sheath comprising the sheath polymer.
Abstract:
A woven or knit fabric containing crimped composite fibers having its air permeability enhanced by water wetting and being useful in clothes such as outerwear, which woven or knit fabric contains 10 to 100 mass% of composite fibers of side-by-side type or eccentric core sheath type composed of polyester resin component and polyamide resin component whose thermal shrinkages are different from each other, the composite fibers having crimps developed by heat treatment. The composite fibers exhibit humid crimp factor HC
Abstract:
A woven fabric structure for outdoor furniture use is provided. The woven fabric structure is a blended fabric containing a coated multifilament yarn (12) and an elastomeric yarn (10) that is resistant to water, ultraviolet, heat degradation or other significant outdoor exposure. The elastomeric yarn (10) is provided in the fill direction and the coated multifilament yarn (12) is provided in the warp direction. Additionally, the coated multifilament yarn (12) can be combined with a yarn such as spun acrylic, polyester, nylon, yarn, texturized yarns; or other uncoated filament yarns.
Abstract:
A synthetic polymer yarn comprising a bicomponent yarn and a second yarn combined to form a single yarn is disclosed. The bicomponent yarn is made up from a first component and a second component each comprises of a fiber-forming polymer and each having different shrinkages from the other to effectuate a bulking effect. This differential shrinkage may be obtained, for example, by using different polymers or similar polymers having different relative viscosities. The synthetic polymer yarn of the present invention has advantageously exhibited an improved visual effect, including a stratified effect, which improves the visual composition of products produced using the yarn. Moreover, the fabrics produced from the yarn have improved hand and stretch and recovery.
Abstract:
A decorative outdoor fabric including a woven structure formed of acrylic warp yarns (10) and at least some of the fill yarns (12) comprising self-coating yarns (14) formed of high melt and low melt yarn constituents. When the fabric is tentered, the low melt constituents melt and cross-flow to the other fibers in the fill (12) and warp yarns (10). Both the warp yarns (10) have deniers in the range of 400-4000 and the fill yarns (12) have deniers in the range of 150-4000. Because of the cross-flow of the low melt constituents, the resulting fabric achieves acceptable abrasion resistance, stability, and load recovery and hand without the need for a latex backing.
Abstract:
An iridescent effect is achieved in satin weave filling-faced fabric using sheath-core filaments wherein the core is dyed to a color that is different from that of the sheath.
Abstract:
[Problem] To provide a woven textile used for products, the textile having hygroscopic properties, durability, and good texture, and having Japanese paper used as a raw material. [Solution] A woven textile obtained by blending a primary yarn comprising Japanese paper thread, and a secondary yarn that is thinner than the primary yarn, wherein the woven textile is a high weave-density woven fabric that has a woven-texture structure comprising a warp (A) and a woof (A) composed of the primary yarn, and a warp (B) and a woof (B) composed of the secondary yarn, and in the woven texture structure, the warp rows have a repeating row structure in which a plurality of threads of the warp (B) are arranged between two threads of the warp (A), and the woof rows have a repeating row structure in which a plurality of threads of the woof (B) are arranged between two threads of the woof (A), and the warp (A) and the woof (A) are interlaced in a flat woven texture structure.
Abstract:
Sheathing assemblies and methods for making and using same are provided. The sheathing assembly can include a body and a barrier secured to a first side of the body. The body can include a plurality of lignocellulosic substrates. Any adhesive disposed between the body and the barrier can consist of: (1) a first adhesive disposed throughout the body and having a substantially constant concentration within the body, (2) a second adhesive disposed throughout the barrier and having a substantially constant concentration within the barrier, or (3) a first adhesive disposed throughout the body and having a substantially constant concentration within the body and a second adhesive disposed throughout the barrier and having a substantially constant concentration within the barrier.
Abstract:
The present invention relates to a fabric comprising a warp system and a weft system. The warp system comprises at least one flame retardant yarn comprising aramid fibers and the weft system comprises at least one core spun yarn. The flame retardant yarn of the warp system is covered by at least 70 % of the weft system. The fabric according to the present invention has an ink receptive surface and a thermal protection surface, and has particularly excellent mechanical, flame resistance and printability properties due to the structure of its weft and warp systems and the materials used and is particularly useful in confection of combat uniforms. Furthermore, the fabric according to the present invention is also exceptionally abrasion resistant, which prevents the fading of a printed image thereon.
