Objective of doubling/Yarn doubling process/Types of doubling/Two for one twister machine/T.F.O

Two for one twister machine: Yarn doubling process: The process of grouping( combining) two or more individual yarns together and then twisting these combined yarns is called the yarn doubling process. Objectives of yarn doubling process: the main objectives of the yarn doubling process are given below: 1 - To improve the tensile strength of the yarn. 2 - To increase the softness of the yarn 3 - To reduce the hairiness of the yarn. 4 - To improve the moisture absorbing capability of the yarn. 5 - To cut the sizing process during weaving. 6 - To improve the evenness of the yarn. Types of yarn doubling process: 1 - ring doubling machine 2 - two for one twisting machine: Ring doubling process: ring doubling process is one stage process. two or more yarn packages are twisted together. the twisting system is the same as the ring frame. Two for one twister machine: this is a two-stage process. in the first stage, two or more individual yarns are grouped or combined together with the help of a parallel yarn winding machine. now a definite amount of twist is inserted into the yarn.
