Crease resistance

The crease resistance or crease resistance is a measure of how much fabric , particularly fabric , are prone to wrinkling and the formation of pressure lines.

This property is measured by a flexometer , the so-called crease recovery angle being determined in accordance with DIN 53 890/91. A distinction is made between dry wrinkle recovery as a wearing property of clothing and wet wrinkle recovery in textile care. A textile with a crease recovery angle of 140 to 150 ° is considered to be very crease-resistant, with 180 ° being the best possible angle and 0 ° being the worst. There is also a dependency of the crease recovery angle on the recovery time.

The tendency to crease depends on the fiber material used , on how the yarn was spun and twisted , on the method of production of the flat textile and on its finishing (e.g. with synthetic resins or by thermosetting ). Textiles made from cotton fibers or regenerated fibers made from them, as well as linen, show particular creasing, while synthetic fibers , silk and wool are crease-resistant. Knitted fabrics have a lot of resistance to creasing.

When embossing creases are deliberately caused.
