Traveler or spinning ring coated with metal sulphides and method for its preparation

Abstract

Provided is a traveler 10 or spinning ring 100 or spinning ring 100 coated with metal sulfide, in particular a traveler 10 or spinning ring 100 coated with tungsten disulfide, forming a traveler 10 or 100 coated with metal sulfide A method of spinning ring 100, and a system using a metal sulphide coated traveler. The metal sulphide coating results in reduced yarn load on the coated traveler 10 or spinning ring 100 , reduced heat generation during spinning operations, and reduced wear of the traveler 10 or spinning ring 100 .

Description

technical field [0001] The present invention relates to a traveler for textile yarn spinning, and more particularly to a traveler having a metal sulphide coating on the traveler surface. Background technique [0002] In traditional compact spinning and twisting operations, a spinning or twisting ring is used to support a rapidly moving traveler around the circumference of the spinning ring. The traveler engages and guides the loose yarn as it twists the yarn and winds it on the spool. [0003] An increase in spinning speed increases the rate at which the traveler rotates around the surface of the spinning ring, thereby also increasing the centrifugal force exerted between the traveler and ring. Furthermore, the larger centrifugal force increases the frictional heat generation of the traveler and the spinning ring, and also increases the wear force exerted on the traveler and the spinning ring. Thus, an increase in spinning speed can result in depleted and / or shortened trav...

AI Technical Summary

Problems solved by technology

Therefore, an increase in spinning speed can result in depleted and / or shortened traveler life, and often also reduced spinning ring life, as the ring's load-bearing surface can flake, chip or otherwise become rough

[0004] As spinning speed increases, the resulting increase in friction or wear between the traveler and spinning ring can lead to breakage of the yarn being spun or twisted

Yarn breaks are particularly undesirable as they lead to downtime in the spinning operation and therefore to lower manufacturing efficiencies

In the case of vertical spinning rings (also called conical spinning rings in the textile industry), the yarns produced on such rings are usually expensive yarns, and therefore, yarn breaks lead to undesired material waste

Usually, for a given spinning ring and traveler combination, there is a practical spinning speed limit that cannot be exceeded, otherwise frequent yarn breakages will occur
