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.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.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.
