The elastomeric yarn for safety applications discloses an elastomeric yarn that reliably breaks at 200% stretch and is therefore appropriate for use with a sacrificial textile. The elastomeric yarn for safety applications discloses the polyurethane segments, the copolymer segments, the necessary plurality of cross-links required to form a structure of a polyurethane based elastomeric yarn that reliably breaks at 200% stretch.

The present disclosure provides combination yarns and carpets formed therefrom, in particular combination yarns comprising a first single primarily PET yarn and a second single primarily PTT yarn, wherein at least one of the first single yarn or the second single yarn includes one or more additives which increases dye uptake.

Cooling by a twist-untwist process, by a stretch-release process for twisted, coiled, or supercoiled yarns or fibers, and methods and systems thereof. High mechanocaloric cooling results from release of inserted twist or from stretch release for twisted, coiled, or supercoiled fibers, including natural rubber fibers, NiTi wires, and polyethylene fishing line. Twist utilization can increase cooling and cooling efficiencies. A cooler using twist insertion and release can be shorter and smaller in volume than a cooler that requires a large elastomeric elongation. The cooler system can be utilized in mechanochromic textiles and remotely readable tensile and torsional sensors.

Various implementations include a method of forming a bulked continuous filament (BCF) yarn. The method includes providing N molten streams of polymer, providing M spinnerets, and spinning the N molten streams of polymer through the M spinnerets. At least a first group of filaments and a second group of filaments are spun through the M spinnerets. The first group of filaments each have a first average denier per filament along a length of the filaments and the second group of filaments each having a second average denier per filament along a length of the filaments, the first and second average denier per filament being different. The method further includes combining the filaments from the M spinnerets together and texturizing the spun filaments.

The application relates to a fire-resistant textile composite having an upper surface and a lower surface. The composite contains a nonwoven layer and a knit layer. The nonwoven layer has a first and second side and contains a nonwoven textile. The nonwoven textile contains a plurality of first fire-resistant fibers, where the first fire-resistant fibers are non-thermoplastic. The nonwoven layer forms the lower surface of the textile composite. The knit layer contains a knit textile having a first and second side and the second side of the knit layer is adjacent to the first side of the nonwoven layer. The knit textile contains a plurality of second fire-resistant yarns, where the second fire-resistant yarns are non-thermoplastic. At least a portion of the first fire-resistant fibers from the nonwoven layer extend through the first side of the knit layer and form the upper surface of the textile composite.

Carbon nanotube (CNT) fiber and sheets formed by a specialized gas assembly pyrolytic reactor method that permits gas phase integration of nano and micro particles (NMPs) are processed into yarn and fabric used in the manufacture of personal protective clothing and equipment that can be tailored via selection of NMPs for a wide variety of functionality depending on target application. The CNT-NMP hybrid fabrics may be designed to exhibit enhanced electrical and thermal conductivity, moisture wicking, air filtering, and environmental sensing properties.

Embodiments of the disclosure provide structures for sensing, activation, and signal networking in a composite textile. According to one embodiment, a composite textile can comprise an activation layer of a reactive yarn knit into a fabric. The reactive yarn can have at least one physical property that changes in response to a stimulus. A signaling layer of a first conductive yarn can be knit into the fabric with the activation layer. The first conductive yarn provides the stimulus to the reactive yarn. A sensing layer comprising second conductive yarn can be knit into the fabric with the activation layer and signaling layer. The second conductive yarn can provide a feedback signal corresponding to the stimulus provided by the first conductive yarn of the signaling layer.

A yarn containing a potential-generating filament. The yarn is constructed such that a positive or negative surface electrical potential is generated by applying an external force to the yarn in an axial direction of the yarn, and constructed such that a controlled surface electrical potential is generated by a maintenance or release of the external force.
