Our yarn evenness testing machine contains two models which are GT-A09 and GT-A09B, and they are applied to assess the evenness, regularity, hairiness, neps and other imperfections in a representative sample of yarn/cotton/man-made fiber wound at a pre-determined pitch onto a tapered black board.
Features of the Yarn Evenness Testing Machine
1. This yarn testing equipment is driven by a synchronous motor and a digital controlling circuit, thus ensuring uniform pitch during a test.
2. Fitted with an alternative pre-tension device, our yarn appearance board winder realizes auto-stop, and the winding speed is adjustable.
3. Our yarn evenness testing machine offers various pitches to satisfy comprehensive requirements of different yarn linear density.
