the original blue jeans were made of this. For reasons of productivity, ring denim was replaced by OE denim at the beginning of the 1970s. In the course of the retro denim wave, ring denim was re-discovered. Today, the product ranges of the fashion-oriented jeans manufacturers cannot be imagined without this type of yarn.

As a specialist in ring spinning, Zinser for many years has been offering a multitude of interesting solutions also for the field of denim ring spinning. Hundreds of thousands of ring denim spindles installed world-wide prove the competence of Zinser also in this market segment. With new innovative solutions particularly developed for denim production Zinser offers spinning mills all over the world a new potential for cost reductions as well as for productivity increases in denim production and thus for acting successfully on the important denim market.

economic efficiency. In some cases, this made completely new appearances possible which mark today’s jeans fashion. The Saurer ring denim solution. Derived from the requirements of the present-day jeans market and thus denim market, Saurer offers the denim ring spinning mills a unique combination of machines and components particularly developed for modern denim production to obtain utmost economic efficiency and optimum yarn quality at maximum flexibility. Trützschler – strategic partner for solutions from bale to sliver.

Zinser CimTrack 4 – creel automation. With the CimTrack 4 creel automation system for ring spinning machines the roving bobbins are directly transported into the ring spinning machine creel. Manual creeling and manual changing between rows of the bobbins in the ring spinning machine creel is dropped. The operator only pieces up the roving ends. Thus the roving bobbins of the roving frame Zinser 670 BigPac with a weight of up to 4 kg must never be moved manually. By using the large bobbins of 20  7, the roving storage at the ring spinning machine is increased by up to 100 %. Zinser 351 – cotton ring spinning machine ideal for denim, too. The cotton ring spinning machine Zinser 351, which is ideal for denim applications, is part of the modular Zinser ring spinning machine concept comprising ring spinning machines for any important ring spinning procedure applied today.

thickness, length and twist are incorporated in the yarn.

When using a gauge of 82.5 mm, a ring diameter of 58 mm and a tube length of 260 mm as well as the automatic doffer CoWeMat 395 with intermediate step it is possible to obtain higher cop running lengths. This results in higher yarn lengths without splices and thus without yarn faults, which means a better quality of the yarn produced. Apart from that, this specification results in fewer doffings at the ring spinning machine as well as in fewer cop changes at the winder and thus in a considerably increased productivity. Zinser FancyDraft – extending the product range. Apart from ring core yarns, ring fancy yarns can also be efficiently produced with optimum quality using the ring spinning machine Zinser 351. For this, Zinser offers the fancy yarn system FancyDraft as an option. With FancyDraft, ring yarn manufacturers are capable of accessing the world of fancy yarns in an economic, efficient and comfortable way. Precondition is the electronically controlled drafting system drive ServoDraft, which is part of the standard equipment of the Zinser 351. Combining ServoDraft and FancyDraft allows the simple production of ring fancy
