Yarn Cone Surface Friction Coefficient Tester

Sled-type friction tester that measures the static and kinetic friction of paper cone surfaces against yarn. Used in textile mills and cone makers to control yarn unwinding performance.

Specification

A weighted sled covered with standard yarn is pulled across the cone surface or board sample at a fixed speed, and the pull force gives the friction coefficient. Surface friction affects yarn slipping and package stability. The instrument helps tune cone coating and surface finish.

Features

• Sled mass 200 g standard
• Pull speed 150 mm/min
• Load cell with 0.01 N resolution
• Static and kinetic coefficient output
• Interchangeable test plane for cones and flat board
