Marzoli’s Mac3000 : The Ultimate Technology for Compact Yarn Production

Despite the high quality of modern ring spun yarns a further increase in yarn quality can be obtained through compact spinning technology. In fact in the standard ring spinning process the fiber bundle coming out from the front cylinder is wider than the spinning triangle. This entails that edge fibers are usually caught in a disordered way into the yarn.

Modern compact technology allows to reduce the width of the fiber bundle before it comes out from the front cylinder and therefore it allows to integrate every fiber into the yarn structure. This grants the following benefits:

  • Reduced yarn hairiness,
  • Enhanced yarn evenness,
  • Higher strength and elongation values,
  • Less variability in yarn strength and elongation,
  • Lower required twist on the spinning frame (higher production),
  • Reduced fiber fly in weaving and knitting operations and consequently fewer defects on the fabrics and higher efficiency,
  • Enhanced fabric properties (fabric strength, abrasion resistance, pilling behavior, visual and tactile characteristics).

The positive effects of compact systems have fostered spinners to use them for the production of an increasing variety of counts and types of yarn, benefitting from higher output quality and process efficiency.

Perforated cylinder vs. apron systems

The most effective way to undertake compaction is through suction and there are two types of devices that allow to suck the fiber bundle: those with a perforated cylinder and those which use aprons. The systems with perforated cylinders have the advantage that they do not require aprons change. Aprons in fact are subject to wear and they need to be periodically substituted. On the other hand, they have the disadvantage that they need to be supervised and constantly cleaned. If this is not done on a regular basis fiber particles can clog the holes of the perforated cylinder and alter compaction performance. With some, but not all, apron systems this is not necessary. The holes are automatically cleaned because the constant tension, flexion and relaxation of the apron continuously modify the cross section of the holes entailing an “auto-cleaning effect”.

Marzoli’s Mac3000 features

Beside being one of the few apron systems which have the “auto-cleaning effect” of the apron described in the previous paragraph, its compacting zone is perfectly visible. This grants an easy supervision of the core area of the device.

The outstanding compacting performance is also assured by the independent modular suction system with large suction tubes and self-cleaning filter. Together these features guarantee constant suction along the entire length of the machine. Furthermore the speed of the suction motor is settable through inverter so that the right suction amount can always be set according to count, type of fiber, desired efficiency and quality trade-off.

The accurate design of the Mac3000’s apron not only guarantees top compacting performances, but it also ensures lower maintenance costs. The disposition of the holes on one axis assures higher resistance of the apron to tension forces; and consequently a longer service life of the component.

Conclusion

Since its launch on the market compact spinning has thrived. The advantages that this process entails, if compared to standard ring spinning, are; higher yarn quality, higher process efficiency and greater productivity at the spinning frame. Therefore compact spinning can be identified as a valuable means to differentiate and achieve a sustainable competitive advantage.

All the benefits that stem from compact spinning are further enhanced by the new Mac3000, the ultimate compact technology designed, developed and produced by Marzoli. With this device the client can rely on a solid and consistent technology; that constantly ensures top compacting performances; with low operating costs and long service life of all its components.
