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.

Sir ye unit ki liye kitna paise lagega

[@Ritity_]

Sir in parallel winding machine "plied yarn" means false twist ?

[@TEXTILEADVISER]

In the parallel winding, two single ply yarn of same count are grouped together
