A yarn storage container for storing a yarn, said storage container comprising a, preferably tubular, container, having an axial length, a, preferably tubular, wall and a first and second axial extremity, the first axial extremity of said container having an opening for receiving an end of a yarn, said second axial extremity of said container being air-permeably closed, said wall is air permeable by means of a plurality of openings present along the axial length of said container. The invention further relates to a yarn storage system comprising a plurality of containers, to a textile production assembly and to methods of producing yarn and textiles.

A wire length calculation system is provided for tracking wire stored on and drawn from a reel. The wire length calculation system may include a detection element, digital logic components, location receiver, enclosure, analytic components, interface component, and sensor module. One or more sensors relative to the reel may detect a position indicative of forward or reverse reel rotation. A processor may analyze signals to count rotations of the reel, which is savable in memory. A battery may provide power. The system may also record the time and location associated with rotations. A method for tracking wire stored on and drawn from a reel using a wire length calculation system is also provided.

A manual winding device comprises a wire bracket, a clamp, a winder, and a tension maintainer. The wire bracket supplies wire, while the clamp holds it in place. The winder, adjacent to the clamp, includes a driving mechanism and a coil former holding unit. The coil former holding unit is configured to mount a coil former. The driving mechanism is configured to drive the coil former holding unit to rotate, winding the wire onto the coil former. The tension maintainer, located between the clamp and the winder, includes a sliding base, a sliding block, and four connecting rods forming a quadrilateral. The sliding block is movably disposed on the sliding base. Two opposite connection points are pivotally mounted on the base and sliding block, while the other two points each hold a pulley around which the wire passes. The tension maintainer ensures the wire's tension is maintained during winding.
