• 

Compliance Standards

FZ/T 70001-2003. FZ/T 71004-2003

Scope of Application

Determines loop length of various yarns and knitted loops. Verifies compliance of different yarn densities (counts) with standard loop lengths.

Product Details

Uniformly spread the twisted yarn under specified tension. Measure loop length compliance through pointer indications.

Structural Features

1. Column fixed to base supports upper sleeve, scale, and serves as lower sleeve guide

2. Rollers installed on both sleeves for tested yarn positioning

3. Upper sleeve position adjustable via vertical axis for different loop lengths

4. Select appropriate weights according to yarn specifications to apply tension through lever mechanism
