ITMA Asia + CITME 2012 Exhibitor Preview: Macart Textiles Machinery Ltd.
BRADFORD, United Kingdom — May 2012 — Macart (Stand No. W3-E41) will exhibit the eco-SpinTwist for
HB acrylic yarn.
eco-SpinTwist
Save energy, workers and floor space when producing industrial HB Acrylic machine knitting yarn.
The new eco-SpinTwist for the manufacture of two fold twisted High Bulk Acrylic industrial machine knitting yarns for sweaters, jumpers, hats, gloves, socks and blankets.
At ITMA ASIA we shall be operating the machine spinning a 2/36 Nm yarn ready for onward processing of yarn bulking.
eco SpinTwist with can feed
110 machines operate in direct floor space of 660 square metres
In comparison the conventional ring spinning, winding, twisting would be approximately 1380 square metres of direct floor space.
In addition to the three significant savings:
• Worker
• Energy
• Floor Space
There are additional benefits for the spinning factory:
• Lower maintenance and spare parts usage
• Lower waste of materials
• Lower requirement of space for movement of textile packages between operations
• Lower requirement of workers for moving textile packages between operations.
A summary of the savings are:
The eco-SpinTwist is supplied with a creel to suit the following roving options:
Flyer Roving tubes
Rub Roving tubes
Rub Roving from can
Production Speeds - Delivery speeds are 230 m/min. The delivery speed remains the same for all yarn counts.
Depending on resultant yarn counts the production of each 4 spindle eco-SpinTwist will be between 7Kg and 2.5Kg per hour. The count range is 2/14Nm to 2/42Nm
The spinning section is a conventional worsted drafting system using double apron drafting with pneumatic weighting.
The draft ratio is adjustable between 15 and 40 in steps of 0.1 by key pad entry on the touch screen.
The fibres to be processed are to be standard worsted length fibre with fibre length of range 60mm to 130mm and mean fibre length approx 90mm
The advantage of the Plc control and AC motors is a reduction in electrical power consumption to 1Kw per hour per 4 spindle machine. The Twist rollers operate on air bearings and the consumption is 0.7Kw per machine.
One operator can run up to 22 machines each when processing 2/36Nm yarn count.The combination of low energy high production per operative and reduced ,waste and factory floor space makes the eco-SpinTwist the best choice for low cost HB acrylic yarn for machine knitting

eco SpinTwist with can feed
The same yarn will be shown on sales yarn package after bulking and a selection
of garments manufactured on WHOLE GARMENT technology flat knitting machines.
Spin and twist on one machine from rovings with a typical 0.8g/m weight to produce two fold twisted yarns in the count range 2/14Nmm to 2/42Nm delivered onto a package for onward processing on the yarn bulking ( shrinking) machine.
The high production delivery speed is 230 metres per minute.
The main advantage for using the eco-SpinTwist is the savings for electricity consumption, workers, factory space and waste when compared with conventional ring spinning, winding and twisting.
The process route using the eco-SpinTwist is to spin, twist and wind a package suitable for onward processing on the yarn bulking machine.
The process route compared to ring spinning is:
A typical installation for the production of 300 Kg per hour of 2/30Nm HB Acrylic hosiery yarn uses the same roving preparation machinery and Yarn Bulking but the eco-SpinTwist is 1 operation compared to the 3 operations of ring spinning, winding and twisting.
The manufacture of the rovings used for feeding the eco-SpinTwist is on a conventional worsted spinning preparation. The production of one set of modern preparation is 300kg per hour for producing rovings of 0.8 g/ m packages or sliver for feeding the creel of the eco-SpinTwist.
To manufacture 2/30Nm HB acrylic hosiery yarn the spinning and twisting before yarn bulking( shrinking) the spinning and twisting is to produce 2/36Nm yarn to allow an approximate 20% shrinkage.
Calculations show that for the 300Kg per hour the machines required will be 110 eco-SpinTwist machines or the equivalent 6000 spindles of ring spinning followed by 120 spindles of winding and 1344 spindles of two for one twisting.
WORKER SAVINGS
One eco-SpinTwist can produce 2.9Kg per hour of 2/36Nm.
One worker can operate 22 machines producing 64 kg per hour. For a production of 300 kg per hour 110 eco-SpinTwist machines are used with a total of 5 direct workers.
In comparison the conventional ring spinning, winding, twisting would require 10 direct workers.
ENERGY SAVINGS
The eco-SpinTwist utilises minimum electrical power. One machine working at 230m/min delivery speed consumes 1.7Kw per hour
110 machines utilises 187 Kw per hour for the production of 300 Kg per hour of yarn.
In comparison the conventional ring spinning, winding, twisting would be approximately 450 Kw.
FLOOR SPACE SAVINGS
The eco-SpinTwist uses a very small amount of floor space for a large production.
An example of the layout in the factory is:
Spin and twist on one machine from rovings with a typical 0.8g/m weight to produce two fold twisted yarns in the count range 2/14Nmm to 2/42Nm delivered onto a package for onward processing on the yarn bulking ( shrinking) machine.
