Nylon yarn

DX321G-(Short Fiber Spun Twisting Machine With 225mm Spindle Gauge) adopts servo system, inverter, PLC, touch screen and microcomputer control synchronous system.

product description

Suits to short fiber and spandex blended TFO twisting, achieved 1.1/1.25/1.7/2.1kg cone same weight feed-in and same weight winding-up cone after twisting. Besides that, DX268G can also produce high quality soft cones directly to cone dyeing. 
Energy saving design, adopts two main motors to drive, which not only solved belt uneven tension problem, also declined energy consumption. 
It adopts servo system, compared to traditional gearbox system, servo system has simple structure, no pollution, less noise, easy maintenance, various shaping technology, and better yarn shaping and machine running stabilization. 
All the high quality parts composed the excellent yarn path, minimized yarn damage during its processing and much better suitable for high quality yarn production request. 
DX321G(Short Fiber Spun Twisting Machine With 225mm Spindle Gauge) also had modified specially for short fiber sewing thread twisting, it provides low energy consumption and less manpower requirement.

Twisting machines for staple fibre yarns

Two-for-One twisting is the most profitable way of twisting yarn
DONGXING TFO (Two-for-One) twisting machines have achieved a dominant market share in this sector thanks to their technological and efficiency advantages - as underlined by sales amounting to more than 2.5 million spindles.
In close cooperation with our customers, DONGXING have developed machines which are able to meet the changing requirements of the market while offering the user exceptional cost efficiency, flexibility and outstanding product quality. By applying the company’s many years of experience in an ongoing research and development program, one which is constantly being modified to incorporate the newest methods and techniques, we shall strive to maintain DONGXING’ s leadership and manufacturing excellence.

Two-for-One Twisting Machine
The DONGXING helps customers save up to 40% in energy costs even for very fine yarn counts. Optimal yarn and package evenness are achieved thanks to a newly designed take-up geometry.

Process handling has a new efficiency dimension:
central setting possibilities
recipe administration
quality monitoring
length measuring and further parameters
really easy operating and absolute safety are integrated

Yarn guiding elements
All elements guiding the yarn at the twisting process are very gentle to the yarn, due to the special wear resistant surface.
