Yarn Twisting Technology
In order to better explain the DirecTwist technology developed by AGTEKS, it is necessary
to understand yarn twisting and doubling technologies. It is also important to express
the benefits gained from both doubling and twisting processes.
What is twisting?
Twisting is the process of wrapping fibers around the yarn axis to provide resistance to
tension forces during fabric formation.
For example, in weaving, both “S” and “Z” twist yarns are used in the warp, creating a
patterned appearance due to different light reflections from these yarns.
Types of Twists by Yarn Count
- Single ply twisting
- Double plied twisting
- Multiple plied twisting
Types of Twists by Twist Count
- Soft twisting
- Normal twisting
- Hard twisting
- Crimp twisting
- Fancy twisting
Purpose of Multiplied Twisting
- Adding strength to a single-ply yarn
- Obtaining yarns with various appearances
- Creating different looks and effects on fabric
- Producing yarns with multiple plies and structures
Doubling and Twisting Machines
Twisting machines fold and twist multiple yarns and resemble doubling machines.
Their main difference is the presence of twisting units, enabling both doubling and twisting.
Doubling & Twisting in Ring Twisting Machines
Ring twisting machines are widely used for flat twisting and can perform both single and
double twisting.
Doubling & Twisting in Two-for-One Twisting Machines
The main tasks of this machine are:
- Giving two twists to the yarn per revolution
- Adding strength by twisting yarns from different bobbins
- Winding twisted yarns at constant tension in long bobbins
- Increasing efficiency with pre-doubling
Duties of Doubling Machines
- Preparing twisting machines by doubling single-ply yarns with equal tension
- Cleansing yarns before doubling using filtering devices
- Improving operation flow with long-length bobbin winding
DirecTwist Technology
DirecTwist technology developed by AGTEKS performs doubling and twisting
simultaneously by acting directly on the yarn. Unlike traditional ring or “2-for-1” systems,
DirecTwist operates at double or higher cycle speeds.
While conventional methods require a bobbin transfer process, DirecTwist allows winding
directly from bobbin to bobbin, reducing processing steps and improving efficiency.
The system integrates the flexibility of ring twisting machines with the high efficiency of
the “two-for-one” method, offering advanced performance.
