The cord includes a carbon fiber cord formed by combining and secondarily twisting a plurality of primary twisted yarns including a carbon fiber. A twisting direction of a primary twist of the primary twisted yarns is the same as a twisting direction of the secondary twist. A primary twisting coefficient of the primary twist is 0.62 to 1.30. A secondary twisting coefficient of the secondary twist is 2.06 to 3.95. A tooth pitch of the toothed belt is within a range of −0.4% to +0.1% relative to a tooth pitch of the toothed pulley around which the toothed belt is wound.

A ply-twisted yarn, and fabric and article comprising the yarn, the yarn comprising: (a) at least one first yarn comprising at least 50 weight percent heat-resistant polymeric fiber, wherein at least 30 weight percent of the polymeric fiber present in said yarn is cut-resistant heat-resistant polymeric fiber having a cut resistance of 500 grams force or higher per ASTM F2992-15; and (b) at least one second yarn having a sheath/core construction with a sheath of halogenated self-extinguishing staple fibers and a core comprising at least one continuous elastomeric filament, wherein 60 to 95 weight percent of (b) is halogenated self-extinguishing fiber, and the halogenated self-extinguishing fiber being in contact with the elastomeric filament and being free or substantially free of inorganic fibers.

A flame-resistant cut-resistant fabric, and a glove or other article comprising the fabric, the fabric comprising: (a) at least one first yarn comprising at least 50 weight percent heat-resistant polymeric fiber, wherein at least 30 weight percent of the polymeric fiber present in the at least one first yarn is cut-resistant heat-resistant polymeric fiber having a cut resistance of 500 grams force or higher per ASTM F2992-15; and (b) at least one second yarn having a sheath/core construction with a sheath of halogenated self-extinguishing staple fibers and a core comprising at least one continuous elastomeric filament, wherein 60 to 95 weight percent of the at least one second yarn is halogenated self-extinguishing fiber, and the halogenated self-extinguishing fiber is in contact with the at least one continuous elastomeric filament, the second yarn being free or substantially free of inorganic fibers; the fabric having a maximum after-flame time of two seconds or less and weight loss of 5 weight percent of less when tested per NFPA-2112-2018.

Disclosed are a medicated thread manufacturing system and medicated thread manufacturing method. The medicated thread manufacturing system includes a first slideway and a second slideway, a thread clamping apparatus and a medicine spraying apparatus that are slidably arranged on the first slideway, and a thread winding apparatus slidably arranged on the second slideway. The thread clamping apparatus is used for clamping two ends of a to-be-processed medicated thread, straightening the to-be-processed medicated thread and twisting the to-be-processed medicated thread in the straightened state into a single-strand rope state. The medicine spraying apparatus is used for spraying a medicine towards a surface layer of the to-be-processed medicated thread in the straightened state. The thread winding apparatus is used for abutting a center position of the to-be-processed medicated thread in the single-strand rope state and pulling the to-be-processed medicated thread towards a direction opposite to the first slideway to fold the to-be-processed medicated thread, and used for rotating the to-be-processed medicated thread, such that the to-be-processed medicated thread winds and extends from middle to two ends to be twisted in a double-strand rope state. The control apparatus controls a matching opportunity of the thread clamping apparatus, the medicine spraying apparatus and the thread winding apparatus. Artificial participation is not needed in the manufacturing process of the medicated thread, such that automation of manufacturing the medicated thread is realized.

A method for manufacturing a gold thread by spirally twisting together a plurality of gold rods. The method comprises passing a gold drawing material through a die aperture to form gold rods. Winding at least two of the gold rods on at least two gold rod receiving rollers. Receiving the gold rods from the receiving rollers and twisting the gold rods to form a gold thread. Winding the gold thread on a gold thread receiving roller and supplying the gold thread from the gold thread receiving roller to a cutter and cutting the gold thread into a certain length.

Disclosed are a high-performance hybrid tire cord capable of realizing high performance and lightweight of a tire, and a method for manufacturing same. The hybrid tire cord of the present invention comprises a PET primarily-twisted yarn, an aramid primarily-twisted yarn, and an adhesive coated on the PET primarily-twisted yarn and the aramid primarily-twisted yarn. In the hybrid tire cord having a predetermined length, the length of the aramid primarily-twisted yarn is 1 to 1.1 times the length of the PET primarily-twisted yarn, after the secondary twist is untwisted.
