2010, smart yarn monitoring,detecting and controlling system was developed which is combined with SCM,micro electronic and OP-TEC.

GTF elastane yarn feeder monitor and controls the change of yarn tension real-time according to high precision and high stability tension sensor.

SF-1 yarn feeding device is applied micro processor,it is different with traditional feeding mode,the yarn can be stored,separated automatically,and the tension can be adjustable.

2009，the independent intellectual property technology—OP-TEC,was applied in yarn feeding device,which solved unsteadiness of traditional circuit,and actualized low yarn tension to 1g.
