What is writhing?
When fibers are wrapped around an axis (the axis of the yarn) to resist the tension that the yarn is subjected to during fabric formation, it is called twisting.
For example, when weaving fabrics, two different types of yarns with "S" and "Z" twist are used in the warp, therefore, since these yarns reflect light in different ways, a patterned fabric is obtained. .
* We can classify twist as follows according to yarn count;
Single layer twisting
Double twisting
Multi-strand twisting
* Twist according to the number of twists;
Soft twist
normal torsion
hard twist
crimp twist
fancy kink
*Purpose of doubling twist:
Increase the strength of single yarn
Get yarn in a variety of looks
Create different looks and effects on fabrics
Obtain multiple layers of yarn with different structures.
And twisting machine
A twister is a machine that folds and twists multiple yarns, similar to a doubling machine. The most important difference between a twisting machine and a doubling machine; the presence of a twisting device in a twisting machine and the twisting of the yarn in addition to the doubling process.
Double twisting of ring twisting machine
The ring twisting machine is one of the double twisting machines used for flat twisting, and can perform single twisting and double twisting.
Twisting on the Volkman twisting machine (2-in-1)
The mission of this machine is;
1- Apply two twists to the yarn in each turn of the yarn
2- Gain strength by twisting yarn from different bobbins
3- The twisted yarn is wound into a long bobbin at constant tension.
4-Pre-doubled yarn improves the efficiency of the machine.
Responsibilities of the parallel machine
The single strands of yarn to be twisted are combined on the bobbin with the same tension to prepare the twisting machine.
If the yarn is not cleaned before pliing, the yarn is passed through a filter to remove defective parts.
It is wound in spool form and in long lengths to facilitate handling of all subsequent processes.
Twisting and twisting are accomplished through technology developed by us. However, unlike other technologies where winding and twisting are carried out by the movement of the yarn, the winding is carried out by the drive of the bobbin. Therefore, ring twisting and doubling machines can run for 5,000 cycles, while our technology can reach twice that and higher.
While ring twist, "2 for 1" and classic twist require a bobbin transfer process, the DirecTwist method can be used to wind from one bobbin to another. This situation affects the number of processes in an enterprise.
The DirecTwist machine was developed by designing the ring twister for flexibility due to external feeding and the efficiency of the "two-in-one" approach.
