Advantage
Two-for-One Twisting TechnologyThe SKS-774 uses TFO technology, allowing the machine to produce two twists for each spindle revolution. This provides high twisting efficiency and helps reduce processing time compared with conventional twisting systems.
Wide Yarn Count RangeThe machine can process different filament yarn ranges according to the spindle gauge configuration:
180 mm gauge: 75D–450D
225 mm gauge: 450D–1500D
This makes the SKS-772 suitable for both medium and heavier filament yarn applications.
High Spindle SpeedThe 180 mm configuration can operate at approximately 5,000–12,000 rpm, while the 225 mm configuration operates at approximately 3,500–10,000 rpm, supporting efficient industrial production.
Flexible Twist SettingThe machine provides a wide twist range, approximately 100–1,800 TPM, depending on configuration. Both S-twist and Z-twist can be produced.
Twisting + Merging FunctionThe SKS-774 is not limited to twisting. It can also perform filament yarn twisting and merging, providing greater production flexibility.
Touch-Screen OperationThe touch-screen control system makes machine operation, parameter setting and production monitoring easier and more convenient for operators.
APPLICATIONS
The SKS-774 Primary TFO Twisting Machine is primarily designed for filament yarn processing.
Typical applications include:
Polyester filament yarn
Nylon filament yarn
Synthetic filament yarn
Industrial filament yarn
Medium- and heavy-denier filament yarn
Twisted filament yarn
Merged / combined filament yarn
Yarn requiring S or Z twist
Pre-twisting before subsequent textile processing
Typical end-use industries include:
Knitting → Weaving → Home Textiles → Apparel → Industrial Textiles → Technical Textiles
The machine can be used when manufacturers need to give filament yarn a controlled primary twist before further processing.
S / Z Twist Capability
The ability to produce either S-twist or Z-twist allows the machine to meet different yarn and downstream production requirements.
Suitable for Continuous Industrial Production
With section-based construction, long-belt spindle drive and multiple machine sections, the SKS-774 is designed for stable, continuous production.

#SKS-775: Secondary Twisting Machine
In the production of multi-ply yarns (such as industrial sewing threads, tire cord yarns, netting cords, and ropes), the twisting process is typically divided into two stages:
Primary Twisting (#SKS-774): The single yarn is given its initial twist in a specific direction.
Secondary Twisting (#SKS-775): Multiple pre-twisted yarns are combined together and twisted a second time—usually in the opposite direction—to balance internal stress, increase tensile strength, and prevent snarls or untwisting.
3. Twist Balance: If the primary twist is in the Z-direction, the secondary twist is typically applied in the S-direction (i.e., S/Z or Z/S structure) to make the finished ply yarn smooth and torque-free.
Versatile Secondary Twisting Capability
Extensively customized based on filament yarn characteristics, offering a low-energy, labor-saving solution that can partially replace traditional compound twisters. It functions as an ideal secondary TFO twister in two-stage (S and Z) twisting processes.
