Fig. 1: Highest blending precision ensures a homogenous appearance of the fabric.
The challenge in the production of mélange yarns is to keep the blending ratio of the colored raw materials constant to achieve a homogeneous appearance of the yarn and fabric. This is especially important if only one raw material in the blend is colored or when different colors are blended. It requires machines in fiber preparation which are able to supply the same color shade over a long period of time. The precision blender UNIblend A 81 meets these requirements. It sets the highest standards for multi-component blends by ensuring continuous mass feeding of the respective raw material components. A deviation of the blending ratios of less than 1% is guaranteed. This precision is particularly important for mélange yarn blending and enables extreme blend compositions in the range of 98/2%.
Oğuz Tekstil is an integrated spinning mill based in Adana, Turkey, with the largest production capacity of polyesterviscose fabrics in the region. The company specializes in the production of mélange yarns, mainly from polyesterviscose blends with different blending ratios, for the most part 67/33%. From these they produce woven fabrics which their customers further process into men and women’s outerwear. Oğuz Tekstil operates whole Rieter ring spinning systems including four precision blenders UNIblend A 81 in fiber preparation.
Efficiency in downstream processes
The precision blending system from Rieter leads to high yarn quality and a homogeneous appearance in the fabric. The ring spinning machines produce with a low number of ends down because of the uniform distribution of the different fibers in the yarn cross-section. The excellent yarn quality also improves the efficiency in downstream processes. There are fewer stoppages in the weaving mill thanks to consistent tenacity and few thin places in the yarn. This gives the fabric a very good appearance with perfectly uniform color.
Flexibility for changing market requirements
Oğuz Tekstil produces 40 tons of yarn per day on 40 Rieter ring spinning machines G 35 and G 38 with a total of almost 70 000 spindles, mainly in the yarn count range of Ne 20 to Ne 50. The ring spinning machine G 38 is an all-rounder that stands for full flexibility in producing standard and special yarns. Yarn parameters can be easily changed on the operating unit thanks to the fully electronic drafting system. The UNIblend additionally enables flexible yarn production: One A 81 can produce up to four different blends and, as a result, is able to feed up to four different carding lines. This increases flexibility: Oğuz Tekstil can respond quickly to the needs of its customers and adapt easily to changing market requirements.
A system is more than the combination of machines
With a Rieter system from fiber preparation to end-spinning, Oğuz Tekstil benefits from having just one contact person for their whole spinning mill. Added to this are correct maintenance, high-quality genuine parts, and extensive technological expertise throughout the yarn production process. “We have chosen Rieter as our business partner in all our investments up to now, because we always feel Rieter’s power by our side in terms of technical, technological and service matters”, states Mustafa Kayan, Manager Oğuz Tekstil.
