摘要： A sea-island composite fiber in which island components are interspersed in a sea component on a fiber cross-section, wherein the island components have a composite structure formed with two or more different polymers joined together, and the ratio (L/D) of the length (L) of the joint section of the island component and the diameter (D) of the composite island component is 0.1 to 10.0. The sea-island composite fiber has satisfactory high-order processability, and therefore can be produced with high productivity and quality using existing equipment, and thin fibers obtained by removing the sea component have functions of structure control while having an excellent tactile impression.

摘要： A continuous filament spun-laid web includes a plurality of polymer fibers within the web, the web having a first thickness and the web being free of any thermal or mechanical bonding treatment. Activation of the web results in at least one of an increase from the first thickness prior to activation to a second thickness post activation in which the second thickness is at least about two times greater than the first thickness, a decrease in density of the web post activation in relation to a density of the web prior to activation, the web being configured to withstand an elastic elongation from about 10% to about 350% in at least one of a machine direction (MD) of the web and a cross-direction (CD) of the web, and the web having a tensile strength from about 50 gram-force/cm2 to about 5000 gram-force/cm2.

摘要： Disclosed are fibers comprising one or more branded fibers which exhibit surface markings in a repeated pattern along the length of the branded fibers. The branded fibers can be incorporated into yarns or fiber bands to represent supply chain information of the yarns, fiber bands, and/or articles made from the yards or fiber bands. In a specific example, branded fibers can be incorporated into an acetate tow band The branded fibers can be recovered from a cigarette filter, the repeated pattern decoded, and supply chain information associated with the acetate tow used to make the cigarette filter, such as manufacturer, customer, ship to location, and even the acetate tow bale, can be obtained.

摘要： Industrial fabrics which contain thermoplastic weft or filling filaments characterized by having at least one segment of the filament's cross sectional area consisting of a foamed polymer are described. The unfoamed segment or segments of the filament contribute axial strength while the foamed segment or segments of the filament contribute to radial compressibility. Industrial fabrics utilizing these filaments have reduced permeability, reduced weft denier, and improved fabric rigidity.
