Crease and Wrinkle Resistance

Introduction

Creases and wrinkles are often seen as an undesirable property of fabrics. The susceptibility of a fabric to creasing it determined by its resilience.

Creases and wrinkles are of greatest concern in the Sports and Leisure and Clothing market sectors, but also relevant to the Interiors market sector. Wrinkles and creases may be unsightly, and usually reduce the lifespan of a textile by making it more susceptible to abrasion.              

In clothing, pleats, also known as pressed-in creases are sometimes applied deliberately, such as in trousers, skirts and suit jackets. It is important not only to understand how to inhibit creasing and wrinkling, but also how to make pleats effectively. The two points are inextricably linked.

Though it may seem a simple subject, the physics and mechanics behind wrinkles and creases are extremely complex and difficult to analyse. This is because textiles are inhomogeneous at several levels, from the fibre, to the yarn, to the final textile structure. Secondly, textile structures are extremely geometrically complex, and thirdly, the deformations involved are multi-dimensional and extremely difficult to mode

The market for easy care chemical finishes is huge, and it is known that almost all cellulosic fabrics have some sort of handle treatment added, and this often includes an easy care element.

Though many people associate creases and wrinkles with ironing, occasionally creases and wrinkles make newspaper headlines, such as in 2007 when the US army changed their uniform.
