AbstractThe present invention relates to knitting technology and is used for adding naked polyethane yarn to T shirt collar in a flat machine. The automatic control method includes three steps of the measurement of yarn tension changing via a sensor and conversion into electric quality; the computer communication between measurement and control via A/D and D/A conversion of a data acquisition card; and the driving of stepped motor by the computer and via a V/F converter. It can result in constant yarn feeding tension and smooth fabric with clear grains and good hand feeling.
