Leather lastometer UI-FT50
Description
Leather lastometer is intended to assess how much a material can be stretched simultaneously in two directions (distended) without being damaged. This simulates conditions experienced during the lasting operation in footwear manufacture.
1. Unuo Leather lastometer Features

2. Leather Ball Burst Tester Principle
Mount sample on the machine, a steel ball was placed at a predetermined speed (12 mm/min)（0.2mm/S） on the center portion of the inner surface of a circular leather sample. A crack was observed on the surface of the leather, and the height & force at which the first crack was generated were recorded, also the broken force and its height.

| What Is Fabric Pills | As described in ISO 12945-1, “pills are formed when fibres on a fabric surface “tease out” and become entangled during wear”. The level of pilling is determined by the rate of a) fibre entanglement leading to pill formation; b) development of more surface fibre; c) fibre and pill wear-off. The rate of these process depend on the fibre, yarn and fabric properties. |
