Shandong Ruyi to grow up with Thies dyestuff weighing station
China's Shandong Ruyi Woolen Textile Co has taken delivery of Asia's first Thies MPS-Colormatic fully-automated dyestuff weighing system ensuring a significant reduction in the labour force.
In a fully automatic operation, China's Shandong Ruyi Woolen Textile Co, has installed the first Thies MPS Colormatic fully automated dyestuff weighing station – in Asia's first – together with a Thies MPS-L chemical supply systems for liquids and 200 litre capacity MPS-D dyestuff dissolving systems
Shandong Ruyi also took delivery of 32 eco-bloc yarn dyeing machines, for the move last year, to its new 3000 m2 facility in Jining hi-tech development zone, Jining City.
As a fully vertical operation, Shandong Ruyi Woolen Textile undertake yarn dyeing, spinning, weaving and finishing before transferring the final fabric to another company in the Ruyi Group for garment make-up.
The woollen company was formed in 1972 with a total of 10,000 spindles. By 1985 this had doubled and today features 60,000.
Further expansion within its weaving operations will see the number of weaving machines increase from 120 and 15,000 m/day to 260 and 26,000 m/day by the end of the year.
“To meet this increased capacity we needed to improve the efficiency and production within the dyeing room,” said Yong Aiguo, Equipment Department Manager.
He elaborated further, “The dyeing units installed in our old factory were not efficient and used, for example, too much water.”
A number of dyeing machines manufacturers were therefore invited to participate in a series of comparison trials and offer a quotation for the new proposed facility.
Thies were found to be the best in the production trials and won the tender to supply 32 eco-bloc yarn dyeing machines.
The eco-bloc units provide a wide range of capacities – 2 x 200 kg, 12 x 120 kg, 6 x 50 kg, 4 x 30 kg and 8 x 10 kg.
“This wide range means we are able to handle large and small production runs and also carry out test designs,” said Dyehouse Manager, Li Lian Feng.
He also confirmed that by changing to Eco-bloc meant Shandong Ruyi has been able to achieve significant water savings with its vastly improved liquidation ratio.
“With the new operation we are able to achieve a really low liquor ratio ensuring at least a 30% saving in water compared with our old system.”
“We have also been able to increase production from 6 t per day to 9 t with the new installation,” he added.
The improved liquor process ensures a more gentle treatment of the yarn. Thread breakages in later processes are minimised and high rates of passages provide fast and even dyes.
To further enhance the production process, automation of the chemical and auxiliaries supply has been another important factor in quality and economising efficiency.
The Thies installation therefore includes two automatic MPS-L chemical supply systems for liquids and three MPS-D dyestuff dissolving systems.
