The present invention relates to plied silver yarn using silver wire as thread, wherein the silver wire is entirely made of silver (Ag) or a silver alloy, to achieve antimicrobial properties and conductivity, as well as to functional fabric using same and to a method for producing same. The plied silver yarn of the present invention uses, as a core yarn, any one of at least one strand of silver wire and fiber yarn made from natural fiber or synthetic fiber, and uses the other as winding yarn covering the core yarn, wherein said one strand of silver wire is produced by casting a silver alloy containing pure silver or copper into a wire rod through directional solidification, and making the wire rod into a microfiber having a diameter of 0.015 to 0.05 mm through a pulling process.

Silver yarn, plied yarn silver yarn, functional fabric using same, and method for producing same

This present invention relates to a spun yarn having novel structure and a method of producing the same. The spun yarn of the present invention consists of a number of fibers arranged in a predetermined direction and twisted together, one end of which fibers is spirally wound around the surface of the yarn. The yarn of the present invention is spun by successively passing a sliver through a pneumatic yarn twisting device, untwisting tube, and false twisting device in turn. The twisting device, untwisting tube and false twisting device are disposed between front rollers and delivery rollers.

Method and apparatus for producing spun yarn

A cover is disposed to cover the entire spinning nozzle zone of a pneumatic spinning apparatus. This cover includes an air suction tube disposed in the interior of the cover, and this air suction tube has the functions of sucking and removing fly wastes generated in the cover and making a contribution to discharge of compressed air jetted from spinning nozzles.

Pneumatic spinning apparatus

A method and apparatus for producing core yarn in which a drafted fiber bundle and a core fiber are supplied to a nozzle block and a hollow guide shaft, and in which vortex air currents are ejected from spinning nozzles, in the nozzle block, to make the fiber bundle wrap around the core fiber evenly and uniformly.

Core yarn production method and apparatus

A woven or knitted fabric with improved properties is formed of core spun yarns each including a (i) core yarn of polyester filaments, mechanical stretch polyester filaments, fire retardant polyester filaments, spandex filaments, high strength polyester filaments, nylon filaments, mechanical stretch nylon filaments, kevlar filaments, polypropylene filaments or a combination thereof; and (ii) a wrapper of cotton staple fibers, polyester staple fibers, rayon staple fibers, modal staple fibers, fire retardant staple fibers or a blend thereof. The fabric may be produced by ring spun, open-end or vortex. The fabric may be produced by different weaving and knitting methods. Regular yarns are mixed in the fabric.

Woven and knitted fabrics with improved properties and core spun yarns for producing the same

A yarn having soft, attractive handle and a structure such that staple fibers are intertwined with each other to cohere into a substantially non-twist yarn. The yarn is manufactured by supplying a substantially non-twist strand of staple fibers to a fluid treatment zone where the staple fibers are intertwined with each other by the turbulent flow, at least part of said staple fibers to be supplied to the treatment zone having a length larger than the distance L between the fiber grasping point in the fiber feed zone and the point where the intertwinement due to the turbulent flow most effectively occurs.
