Xianyang Textiles has issued a positive appraisal of Zinser’s ring spinning system, after operating it almost for five years, since it has exceeded the company’s expectations.

State-run Chinese textile firm Xianyang Textiles Group Company Ltd. has been using 96 ring spinning machines made by Zinser since 2013, in conjunction with the Autoconer package winding machine from Schlafhorst, according to a release.

With around 5,000 employees and a production capacity of 400,000 spindles, Xianyang Textiles is one of the largest textile companies in north-west China and boasts an annual production of 50,000 tonnes of yarn. The company processes cotton, manmade fibres and their blends to create high-grade yarn in the quality ranges between Ne 21 and Ne 120.

Xianyang Textiles operates its own weaving mills and dye shops, thereby covering a broad scope of the textile net product chain. The yarns are used in clothing, household textiles and technical textiles. Part of the production is exported to over 50 countries, with a particular focus on Europe, North America, Japan, Korea, South-East Asia and Africa.

Stable precision technology reduces spinning costs

After commissioning ZinserRing 71 spinning machines, Xianyang Textiles achieved a significant reduction in spinning costs as well as a drop in power consumption. With its energy-saving tangential belt drive, its precision-mounted high-speed spindles featuring a low power requirement and its energy-efficient motors, the ZinserRing 71 produced more yarn, using less electricity. The stable and reliable design of the ZinserRing 71 enabled Xianyang Textiles to increase spinning speeds without the risk of yarn breaks.

The integrated OptiStep software has ensured that the start, coast-down as well as operational spinning speeds are optimally attuned to the technological spinning limit and enabled the bobbin build to spin at maximum speed during every phase.

Quality through mechanical weighting arms

The drafting system of the ZinserRing 71 features mechanical weighting arms which guarantee consistent pressure at all spinning positions.

This reliability leads to yarn values that are consistent at all times, enabling Xianyang Textiles to achieve top quality with maximum process reliability and significantly reduced maintenance input.

CoWeMat – doffer with process reliability

The CoWeMat remains the leading technology for doffing automation. With its renowned process reliability and dependable operation, the CoWeMat has reduced personnel costs and increased efficiency.

Fast, reliable automatic bobbin changing on the ZinserRing 71 by CoWeMat made it possible to utilise the production capacity to optimum effect, as it performs the work arising at intervals without the need for staff.

"In contrast to our previous installations, there are no bottlenecks, waiting times or downtimes", Xianyang Textiles Head of Spinning Department Yang Renhong said.

"This ensures highly efficient operation of the ring spinning system at all times. In addition, the CoWeMat has reduced maintenance input during the doffing process to a minimum, providing a level of reliability that has enabled us to reduce our personnel costs," he said.

Personnel enthused due to easy operation

How difficult is it for the operating personnel to produce a consistent level of quality over an extended period or to reproduce a desired quality at any time?

In this regard, the ZinserRing 71 has once again exceeded the expectations of Xianyang Textiles.

Machine operators were delighted with the straightforward operation, where all spinning parameters and a lot data can be input centrally on the EasySpin control panel.

The simple operating concept and the easy-to-understand input assistants speeded up operations and prevented setting errors.

Safe processing of cotton, synthetics and blends

Regardless of whether the ZinserRing 71 is required to handle synthetic staple fibres and their blends or natural fibres made from cotton, it has ensured that processing is consistently safe, reliable and productive.

"The markets are constantly changing. There are fluctuations in the availability of raw materials and in the level of demand for the various yarns. The ZinserRing 71 puts us in a position where we can ideally meet changing market requirements, as we want to continue to grow regardless of fluctuations in the market," Yang said.

Partnership with the automation supplier

From the perspective of Xianyang Textiles, the ZinserRing 71 is the perfect solution for the latest requirements of the Asian textile industry. Due to the increasingly difficult issue of workforce availability, spinning mills must make themselves less and less reliant on personnel.

Delivery of any desired yarn at a guaranteed quality and at an unrivalled price-performance ratio is what companies want from their modern machinery. Zinser has proved to be a powerful partner of Xianyang Textiles, which additionally offers integrated automation solutions from roving frames and ring spinning machines, to winding machines.

Featuring reliable high-level technology, the ZinserRing 71 can be integrated into a fully automated production system at any time, achieving maximum profitability and ensuring dynamic growth, the release stated.
