The invention relates to a yarn feed apparatus for a workstation of a cabling machine for feeding a creel yarn from a feed package arranged on a bobbin creel or from a transport conveyor arranged above the cabling machine to a cabling apparatus equipped with a cabling spindle and/or for feeding a starter yarn from the cabling spindle to the creel yarn, a workstation of a cabling machine for producing a cabling twist and a method for feeding a creel yarn using a yarn feed apparatus of this type.

The present disclosure discloses alloy filament and simple yarn blending equipment and a process, and belongs to the technical field of textiles. The equipment comprises a machine head, a machine body, a machine tail, and a computer control box arranged on one side of the machine head; and an upper roller, a first covering spindle, a second covering spindle, a heat setting box, a lower roller, and a winding device are sequentially arranged in the machine body from top to bottom. The equipment is technically modified through the solution to achieve completion of the procedures such as covering, twisting, spooling and the like of the yarn on one piece of equipment, the yarn is integrally formed, the process is the first in China, and is equivalent to a chip in the spinning industry, the labor as well as time and energy are saved, and economic efficiency is greatly improved.

Actuators (artificial muscles) comprising twist-spun nanofiber yarn or twist-inserted polymer fibers generate actuation when powered electrically, photonically, chemically, thermally, by absorption, or by other means. These artificial muscles utilize polymer fibers non-coiled or coiled yarns and can be either neat or comprising a guest. Devices comprising these artificial muscles are also described. In some embodiments, thermally-powered polymer fiber torsional actuator has a twisted, chain-oriented polymer fiber that has a first degree of twist at a first temperature and a second degree of twist at a second temperature in which the bias angles of the first degree and second degree of twist are substantially different.
