improved running properties at the warping and weaving stages. Apart from the chance to obtain considerable cost savings in the subsequent processing stages it is also possible to execute an aimed yarn engineering with the Zinser 351 C3. This yarn engineering results in new textile products and involves new value added potential in the spinning mill. Combed compact yarns – Established in the market. Compact spinning is used world-wide for producing high-quality yarns of combed cotton. In this field, the compact spinning technology has established itself today. Compared to conventional ring spinning, this technology results in a real progress in yarn quality. The progress mainly lies in the higher fibre strength utilization and in the reduction of yarn hairiness. Here, particularly the longer hairs are eliminated which have a negative influence on further processing. Typical final products as high-quality business shirts show these excellent yarn quality.

and further yarn processing for the field of carded cotton yarns in clearly defined spinning trials.

– Tenacity values can also be clearly improved in the compact spinning process. The trial series showed up to 20 % higher values compared to the values of conventionally spun yarns.

Apart from these excellent yarn values the following essential findings could be obtained for carded compact yarns: – Productivity increase at the spinning machine by up to 10 % through increasing the spinning speed and / or reducing the yarn twist. – Displacement of the spinning limit by up to 15 %. Nearly two thirds of the world-wide spun ring yarns are carded ring yarns. Applications for these coarser yarns are mainly in the field of knitted goods, here particularly in circular knitting. But also woven goods, for example for outerwear, are made of carded ring yarns. In these areas there is an enormous potential for carded compact yarns. Possible applications for carded compact yarns are knitwear for T-shirts as well as underwear and socks.
