Corespun and Sirospun yarns
Top-quality elastic and non-elastic core yarns are spun on state-of-the-art Rieter G 33 ring spinning frames.
Medium, long and extra-long staple combed cotton qualities, as well as viscose, micromodal and blends of these with well-known elastanes within the range of 11 to 156 dtex are processed.
The spun yarns are wound onto Murata coners equipped with Uster Quantum yarn cleaners. Core yarns are usually spliced but can likewise be knotted, if so required by the customer.
To ensure high-grade and finest qualities, it is crucial to carefully select the raw materials used, to implement a 4-phase foreign fibre detection process and to constantly check the relevant quality parameter applied in our textile laboratory.
In this spinning process, a roving yarn is spun around the elastane. Finished product fineness grades of Nm 20/1 to Nm 170/1 are, thanks to the inherent benefits of the natural fibre, combined in an ideal way with the technological advantages of an elastane core. This yarn is used for woven or knitted fabrics.
In this spinning process, two roving yarns are spun around the elastane in a single working cycle. Compared with conventional Corespun, the resulting spun yarn offers distinct advantages in processing as well as in final fabric quality - such as enhanced evenness, lower hairiness and improved core covering since the elastane component is completely enclosed. We have protected these Sirospun yarns featuring utmost quality levels as registered trademarks with the brand names cotton star® and elasto star®, respectively. They are supplied by us in finished product fineness grades of Nm 50/2 to Nm 280/2.
With cotton star® and elasto star® we have developed a yarn that incorporates each and every customer requirement. The velvety soft cotton or micromodal material with its exquisite look is characterised by its delightful and unique wearing comfort and natural feel against the skin. These sophisticated qualities are mainly used in elastic woven fabrics as well as for bodies and seamless items.
Non-elastic core yarns
Our product range furthermore includes hardcore yarns with a core made not of elastane but of high-tenacity polyamide or polyester filament yarn with various properties. In addition to their conventional use as sewing threads, these core yarns are increasingly being used for technical applications, including shielding electromagnetic radiation.
