1 - EliTwist – A Compact yarn for Superior Demand
The purpose of this article is to present another variant developed for this process, which allows the very efficient production of a two-ply compact yarn for superior demands directly on the ring spinning frame. EliTwist even improves the utilization of fibre substance further.

2 - Principle of the EliTwist Method
The patented EliTwist process allows to reduce the twisting triangle to a degree that the restrictions mentioned under item 2 are eliminated. This is realized by the two fibre strands first passing a condensing zone. During condensing, both components get closer and reach a minimum distance by means of two suction slots in the condensing zone in a V-shaped arrangement Owing to condensing, the two components – after leaving the condensing zone – do not form spinning triangles. Consequently, no fibres are sticking out, spreading up to the other yarn component or not being embedded in the yarn.

3 - Draft and yarn Count Range
For the EliTwist Method, two separate rovings are fed to each spinning position of a drafting system, which are drafted and compacted separately. Thus, the doubling effect only occurs when both components are united in the twisting triangle. This means that both components must be considered as a single yarn of the same count, as regards their possibility of spinning.
 


4 - Production of Two-Ply yarn on the ring Spinning Frame
In order to spin two-ply yarn directly on the ring spinning frame, two fibre strands drafted parallel at a relatively large distance must be combined in a twisting point after passing the front roller pair of the drafting system. The specialty of such yarns is that the direction twist in both legs is the same as in the resulting two-ply yarn.



5 - Essential Characteristics of EliTwist and Economic Considerations
The utilization of fibre substance achievable with EliTwist is unrivalled by any other spinning process presently offered. Outstanding characteristics are:

• Very smooth structure, closed yarn surface, circular yarn cross-section
• High regularity
• Considerably deduced fibre loss at the drafting system from roller pair
• Extremely low hairiness, especially of long fibres(S3,>3 mm)
• High breaking load and elongation, maximum work capacity
• Very high yarn slippage and abrasion resistance
• Very low pilling tendency
• Low twist coefficients
• Unrestricted traveler speeds
• Saving or even elimination of sizing agent in most applications
• No restrictions in splicing

6 - Special Properties
Due to its special properties, EliTwist is particularly suitable for being processed on highly productive air-jet weaving machines. As regards two-ply core yarn, production can also be considerably increased and the filament percentage be reduced. The filament fed in the centre of the twisting triangle is perfectly covered by the two yarn legs. Undesired “naked points” are avoided, and consequently higher spindle speeds are possible. Furthermore EliTwist offers the possibility of producing numerous other interesting yarn designs and special purpose yarns for most different applications.
