VIT 110 – Fabric Crease Recovery Tester

Testing Method

Fabric Crease Recovery Definition
Creasing occurs when fabric bends or deforms locally due to external forces, making the fabric difficult to return to its original flat state even after the external force is removed. This phenomenon is referred to as “crease.”

Importance of Crease Recovery
Crease resistance is the fabric’s ability to withstand bending and deformation caused by rubbing. This property is also known as the fabric’s ability to recover gradually to its original state after the external force is removed, thanks to its fast and slow elasticity.
Fabrics with poor crease recovery are prone to creasing when worn, which not only negatively affects the appearance but also accelerates wear along the creases, speeding up the fabric’s deterioration. Wool fabrics, for example, are known for better crease recovery. Thus, crease recovery is a vital factor in evaluating the fabric’s wool-like quality.

Crease Resistance vs. Crease Recovery
While “crease resistance” and “crease recovery” are often used interchangeably, they are distinct terms in different contexts. Crease recovery is influenced primarily by the fabric’s inherent physical properties and its finishing process.
There are two methods to evaluate fabric crease recovery:

1. Appearance Method: This method evaluates the fabric’s appearance and how it recovers, although it can show some deviation.
2. Crease Recovery Angle Method: This method, used with the Crease Recovery Tester, provides more accurate results by measuring the recovery angle of the fabric.

To counteract the negative effects of creases, the textile industry has explored improving crease resistance through new raw materials, weaving techniques, fabric structure adjustments, and optimized finishing processes.
