Environmental news and technical  innovation in the nonwovens sector

GRAZ - International technology Group Andritz has received an order to supply four new needlepunch lines for nonwoven production from Chongqing Double Elephant Microfiber Material Co., Ltd., China. The lines are scheduled for installation and start-up in the fourth quarter of 2021.

The needlepunch lines by Andritz are designed to process islands-in-the-sea fibres dedicated mainly to the production of high-quality synthetic leather products. Once completed, the lines will produce 30 million metres a year of microfibre nonwoven materials.

The production lines are equipped with an Andritz carding machine and the newly developed Profile crosslapper as well as the advanced-technology ProWid closed-loop system from Andritz. The system can monitor the weight uniformity (CV%) of the entire product online and predict the weight distribution changes caused by the bonding process.

In addition, the web weight can be reduced by controlled stretching, which solves the issue of fibre accumulation at the edges caused by traditional crosslapping methods. Both the weight and the uniformity of the product can be automatically adjusted via the closed-loop function as set on the Andritz gauge.

Chongqing Double Elephant Microfiber Material Co., Ltd., wholly owned by listed Wuxi Double Elephant Microfiber Materials Co., Ltd., is located in the Changshou National Economic and Technological Development Zone of Chongqing City.

The company is active in the research, development and manufacture of microfibre materials, polyurethane synthetic leather and polyurethane resin.
