Twisted or TFO yarn:In this article, we will examine twisted filament Twisted or TFO yarn The twisting process in polyester filament yarns increases the cohesion of the filaments. Twist refers to twisting the yarn around its axis, and its increase, within the optimal range, increases the strength and improves the yarn underhand.
Method of production
ITY, FDY and DTY polyester filament yarns, BCF yarn, melange yarn, nylon yarn and other yarns are subjected to twisting process in single or multiple layers. One of the common methods of producing twisted yarn (Twisted/TFO) is to use a ring spinning machine. The ring spinning machine consists of a rack, yarn spinning section and yarn twisting section on the bobbin, which performs the yarn spinning operation using a ring (or glasses) system. In this method, the yarn is opened from the shelf, then simultaneously twist and wound on the bobbin.
Another method is to use a two for one twisting machine, which is abbreviated as TFO and the resulting yarn is also called TFO yarn. In this method, unlike the method used in the ring machine, the yarn is first unwound from the bobbin and after applying swing, it is wound on another bobbin. The two for one twisting machine includes the main parts of the bobbin holder, yarn tension, drum and balloon holder. The two-for-one twisting method has production capabilities (including the number of twist per meter) and a higher production speed, so it is used more often.
Properties
Twisted yarn or TFO finds special applications due to the appearance and underhand properties using the twisting process. twisted yarn is used in all kinds of silk, crepe, clothing, curtain, etc. fabrics.
Characteristics of twisted filament polyester yarn (Twisted/TFO) produced in Mr Yarn:
