Fibers are clad with a responsive liquid crystal material and a polymer. The clad fibers may be useful for advanced textiles and wearable sensors.

A method of manufacturing artificial turf creating a liquid polymer mixture, wherein the polymer mixture is at least a two-phase system. A first one of the phases includes a first polymer and a first dye, and a second one of the phases of the polymer mixture includes a second polymer and a second dye of a different color than the first dye. The first and the second phase are immiscible, the first phase forming polymer beads within the second phase. The method further includes extruding the polymer mixture into a monofilament including a marbled pattern of the first and second color; quenching the monofilament; reheating the monofilament; stretching the reheated monofilament to deform the polymer beads into threadlike regions and to form the monofilament into an artificial turf fiber; and incorporating the artificial turf fiber into an artificial turf backing.

A moisture absorbent core sheath composite yarn has a sheath portion polymer that is a polyamide and a core portion that is a thermoplastic polymer, and has a moisture absorbance/desorbance (ΔMR) of 5.0%, wherein the ΔMR maintenance rate after 20 washes is 90%-100%. The core sheath composite fiber has high moisture absorbance, is more comfortable than natural fibers, and has wash resistance with moisture absorbance that stands up to real use and color fastness.

A first component of the multi-component filament comprises a first thermoplastic polymer and a second component of the multi-component filaments comprises a second thermoplastic polymer. The first and the second thermoplastic polymer have different yield behavior, whereby the multi-component filaments are self-crimping.

The present disclosure is to a fly fishing line and a method of making a fly fishing line. The method includes preparing a composition comprising a polymer resin, a co-polymer of silicone, and one or more other polymeric materials. The method includes applying the composition around an elongated core. The method also includes exposing the composition to conditions that form a coating around the elongated core thereby forming the fly-fishing line. The composition is a plastisol composition and the polymer resin is a polyvinyl chloride resin. The fly fishing lines include an elongated core a coating disposed around the elongated core. The coating comprises a polymer resin, a co-polymer of silicone, and one or more other polymeric materials.
