Abrasion and Pilling of Fabrics https://www.pandasilk.com/ During wear and washing, fabrics are affected by friction forces during usage. Friction forces results in the abrasion and pilling of fabric.
Abrasion Abrasion is the mechanical deterioration of fabric components by rubbing against another surface. Abrasion ultimately results in the loss of performance characteristics, such as strength, but it also affects the appearance of the fabric. Although maintenance of strength and other properties that enter into performance is crucial in the life of a fabric, often apparel and other textile items are discarded because the fabric appears worn, sometimes long before fabric strength is significantly compromised.
Types of abrasion • • • •
As a fabric rubs on another fabric; As a fabric rubs against another object; As fibers or yarns within the fabric rub against each other when the fabric bends, flexes, or stretches; As dust, grit, or other particles held within the fabric rub against fibers inside the fabric.
In many end uses, two or more of these types of abrasion occur simultaneously.
Properties affecting abrasion resistance 1. Fabric properties One of the most important influences on the abrasion resistance of a textile fabric is the fiber content. Some fibers are inherently more resistant to abrasion than others. For example, nylon and polyester have a high ability to absorb energy (i.e., toughness), which contributes to the abrasion resistance of fabrics made from these fibers. Nylon's high resiliency and low coefficient of friction also contribute to good abrasion resistance, making nylon an appropriate choice for end uses such as jacket shells, rope, carpet, or luggage. 2.
