Abstract: The present invention relates to a sanding apparatus used for the production of air textured yarn and false twist yarn. The apparatus comprises a motor, a housing provided with a guide groove, and a frictional disk connected to the motor and enclosed in the housing. The apparatus can be arranged in an intermediate section of the production process to generate short hair on the outer surface of yarn by the contact between the frictional disk and moving yarn. Accordingly the products made by the apparatus have soft tactile feelings when touched.

Abstract: The present invention relates to conducting yarn. The conducting yarn of the invention mainly consists of a strand of nonconductive yarn crossedly wrapped with two stainless steel threads. The yarn made in this way has better softness, high impact strength, and good conducting properties, and is especially adaptable for use in fencing jackets.

Abstract: A device is provided for applying a source of high-voltage static electricity in combination with suction to remove trash and dust from raw cotton in a preparation process before carding. The device includes a pair of plastic plates disposed on opposing ends of a housing. A pair of copper plates extend between the plastic plates and have a plurality of holes formed therethrough. The sources of static electricity are connected to the pair of copper plates and the raw cotton fibers are passed therebetween. A suction of 30-100 Pa is applied within the housing for removal of the trash and dust.

Abstract: A system for spinning is provided where a pair of carding machines are arranged side by side. A first drawn sliver is produced by feeding two carded slivers simultaneously into a sliver collector and a drafting system. The drafting system includes a pair of linear density sensors disposed at the inlet and outlet thereof and coupled to a control system for controlling the draft ratio of a first drafting zone to maintain the inlet and outlet linear density at a predetermined value.
