COM-4 (Comfor spin) AND ELITE YARNS



With the Comfor Spin  technology a new yarn with perfect yarn structure – the COM4  yarn - has been established in the market.

 With the help of a microscope the structure of the yarns can easily be compared: The conventional ring yarn shows to be far less perfect than commonly assumed. The long, protruding fibres cause a number of problems in downstream processing. COM4  yarn shows a very compact structure with highly parallel fibres and much less disturbing hairiness.

The air current created by the vacuum generated in the perforated drum condenses the fibres after the main draft. The fibres are fully controlled all the way from the nipping line after the drafting zone to the spinning triangle.

 An additional nip roller prevents the twist from being propagated into the condensing zone. The compacting efficiency in the condensing zone is enhanced by a specially designed and patented air guide element.

Optimal interaction of the compacting ele-ments ensures complete condensation of all fibres. This results in the typical COM4 ® yarn characteristics.

The ComforSpin ® technology allows aero-dynamic parallelization and condensation of the fibres after the main draft. The spinning triangle is thus reduced to a minimum. The heart of  ComforSpin   machine is the compacting zone, consisting of the following elements:

• perforated drum

• suction insert

• air guide element

The directly driven perforated drum is hard to wear  and resistant to fibre clinging. Inside each drum there is an exchangeable stationary suction insert with a specially shaped slot. It is connected to the machine’s suction system.



The operating method of the SUESSEN EliTe  Spinning System is well-known. After the fibres leave the drafting system they are condensed  by an air-permeable lattice apron,which slides over an inclined suction slot.The fibres follow the outer edge of this suction slot and at the same time  they perform a lateral rolling motion.

Above the front bottom roller of the drafting system, the fibre band  influenced by high draft  is spreading.In the area of the suction slot,which is covered by the lattice apron,the fibre band is condensed.Commencing from the semi-dotted clamping line of the EliTe Q Top Roller,twist is being inserted.There is no spinning triangle.


The improvement achieved is shown in Fig .The left side displays the fibre triangle at the exit of a conventional ring frame drafting system.The twist imparted by the spindle cannot flow up to the clamping line.The outer fibres spread out and are thus more highly tensioned than those on the inside. The right side of the picture does not show a spinning triangle.The yarn twist flows right up to the clamping line.The yarn is round and smooth.


Since the spinning triangle is very very small, the end breaks will be very less and therefore the fly liberation will also be less.

Condensing of the fibr bundle,which follows the drafting process,can already be seen as a significant  development of the ring spinning technology.Condensed ring yarn is more  than a speciality.In view of its manifold advantages.

It is of technological importance that the suction leve l relevant for the condensing operation is exactly the same for all spinning positions. To fulfil this criteria,individual motors combined with suction units for  6 spinning positions,have  been arranged accordingly.This provides short air-flow distances with identical negativ pressures at all spinning points .  

During yarn formation all fibres are perfectly condensed and gathered parallel to each other in the compacting zone. Consequently all fibres are twisted in and contributing to the superior fibre utilisation rate compared to conventional ring yarn. The result is exceptionally low hairiness combined with higher yarn tenacity and elongation. These are the unique characteristics of these yarns.
