Introduction of the company Gebr. Otto (Dietenheim, Germany)

Good day. My name is Günther Schuster and I am the Technical Manager of the spinning mill at Gebrüder Otto in Balzheim. Mr. Istrefi asked me to introduce Otto and briefly describe why we work with the Swinsol compact system.

Let’s first start off by introducting our company:

The spinning mill of Gebr. Otto based in Dietenheim in Upper Swabia is one of Europe’s leading suppliers of textile solutions. The company has traditionally focused on high-quality yarns and threads made of cotton, which are manufactured in its own spinning, twisting and dyeing mills. In addition, Otto offers a growing portfolio of technical textiles. The family business is owner-managed in the fourth generation. Sustainability, customer orientation and innovations for the textile future determine our work and actions. Our own brands such as Cotton since 1901, Piumafil and recot² as well as a large number of awards and certifications are the best proof of this claim.

Future since 1901: Looking ahead is a tradition at Gebrüder Otto. Above all, we set standards in technology: Thanks to our know-how, which includes a variety of technologies, and our modern machine park, our textile solutions are ahead of its time. The independence of the company is also unique. For us, the family business stands for a sense of responsibility, entrepreneurial foresight and a sense of duty. Last but not least, we owe our success to our committed employees. Many have been loyal to the company for decades, some even in the second or third generation. And the fact that no machine can replace people is already evident when selecting the cotton. We only use first class raw cotton. It must have high values ​​in terms of staple length, purity, meet micronaire and pressley values. The same strict standards apply to the quality of the yarns we produce.

Control is a crucial prerequisite for quality. A close-meshed testing and control system ensures that we always receive a consistent quality of our products from the raw material to the dispatch of the products. The entire production process is largely fully automated. With the testing equipment, computer data systems and online monitoring we use, we can meet all of the information gathering requirements that are necessary for a complete quality assurance system.

Our company is technologically at the forefront. We have an extensive quality management system and are certified according to ISO 9001, 14001, 5001, STEP, GOTS, IVN BEST, GRS, as well as Ökostandard 100.

 

 

The change to mechanical compact

The transition to our mechanical compacting system is rather easy. Like already mentioned in the previous paragraph “especially in technology, we set high standards and thanks to our know-how, which includes many technologies, our textile solutions are ahead of the time.” That also applies to the mechanical compacting system. Since early 2003 we saw potential in the mechanical compact solution. In 2003, the mechanical compacting system was still at the very beginning of its history. The yarn spun from it was ridiculed by the textile world as a so-called dummy compact yarn. In our company, however, the ingenuity and at the same time the simplicity of the system, which can be carried out like a normal cylinder change on the ring spinning machine during changeover, were recognized. At that time still with the ceramic compressors, yarns were spun up to a maximum of Nm 60. Today we spin yarns up to Nm 170 without any problems with the latest generation of compactors. However, it took almost two decades until the yarn values ​​spun with the mechanical compact system were equivalent to those of conventional, i.e. air-spun yarns. Countless different compactor types have been designed with CAD (especially in the last 2 years). These could then be printed out immediately on the 3D printer, which was a great advantage, because a yarn could be spun out very quickly and the yarn values ​​determined or compared to each other. We found that every edge, every curve, the height of the channel, etc. had an impact on the IPI values. Yarns up to a maximum of Nm 60 were spun.

 

The Compact System from Swinsol

A major further development was the RECOMPACT 3.0 system manufactured by Swinsol. Up until now, all compact systems had the disadvantage that the covers had to be renewed or ground (depending on quality requirements) within a short period of time. Thanks to the Recompact 3.0, the traversing can be adjusted manually during production of the ring spinning machine, so that we now have three times the service life of the spinning covers. In addition, we will probably soon be able to increase this service life by a factor of 6 again with newly developed cylinder covers.

As already described, it was a long way before spinning with mechanical compactors was really mature and the yarn values ​​spun from them were really on par with those of air-compacted compact yarns. Even with the current Swinsol system, we still have to consider a few factors in the spinning mill. The parts responsible for guiding the fibers in the drafting system must be optimally adjusted to one another. The selection of the traveler type is very important, for example, and the ring spinning machine should also be suitable for the yarn path. And by adjusting those with our expertise, we achieve astounding yarn values.

The compact system from Swinsol convinced us for the following reasons:

1. Brilliantly simple
2. No additional energy costs, as this is the case with the competitors, for example
3. 3x longer service life of the covers (soon to be 6x)
4. Existing ring spinning machines can be converted relatively quickly to compact yarn and also quickly to conventional yarn
5. The yarn values ​​spun from it can absolutely keep up with those of the competition
6. Value for money is significantly better than that of the competitors
7. Optimal service is guaranteed by Swinsol
