Abstract:
An article including multi-component fibers and particles is disclosed. The multi-component fibers include at least a first polymeric composition and a second polymeric composition, are adhered together, and are non-fusing at a temperature of at least 110°C. At least a portion of the external surfaces of the multi-component fibers includes the first polymeric composition. Particles are adhered or directly attached to the first polymeric composition on the external surfaces of at least some of the multi-component fibers along their lengths. The particles include at least one of activated carbon, superabsorbent polymer particles, and abrasive particles. In some embodiments, the particles are distributed throughout the thickness of a web of the multi-component fibers. A method of making the articles is also disclosed.
Abstract:
A layered non-woven textile may be incorporated into various products, including apparel. The layered non-woven textile may be formed from a first layer and a second layer. The first layer is formed from a plurality of first filaments that include a first thermoplastic polymer material with a first melting temperature. The second layer is located adjacent to the first layer and secured to the first layer. The second layer is formed from plurality of second filaments that include a second thermoplastic polymer material with a second melting temperature. The first melting temperature is lower than the second melting temperature.

Abstract:
A reversible, heat-set covered fiber is described, the covered fiber comprising: A. A core comprising an elastic fiber comprising a substantially crosslinked, temperature-stable, olefin polymer, and B. A cover comprising an inelastic fiber. The fiber is heat-set by a method comprising: (a) Stretching the covered fiber by applying a stretching force to the covered fiber; (b) Heating the stretched covered fiber of (a) to a temperature in excess of the crystalline melting point of the olefin polymer for a period of time sufficient to at least partially melt the olefin polymer; (c) Cooling the stretched and heated covered fiber of (b) to a temperature below the crystalline melting point of the olefin polymer for a period of time sufficient to solidify the polymer; and (d) Removing the stretching force from the covered fiber.
