Testing of Fibres, Yarns and Fabrics and Their Recent Developments
Published in Asis Patnaik, Sweta Patnaik, Fibres to Smart Textiles, 2019
The dimensional stability of a fabric is a measure of the extent to which it keeps its original dimensions (length and width). A higher dimensional stability of textiles is always desirable. A decrease in dimension is known as shrinkage, while an increase in dimension is known as growth. Usually fabrics shrink during garment manufacturing and washing due to relaxation of the fibres/yarns, swelling of fibres and felting. To calculate the shrinkage of a fabric, a specimen of size 50 cm × 50 cm is taken and marks are placed at a distance of minimum 25 cm in both directions of the fabric (along the length and width of the fabric). After marking, the fabric specimen is washed in a washing machine with suitable specifications. Washing is followed by rinsing and drying. Dried specimen is conditioned in standard testing atmosphere and the markings are re-measured. The percentage shrinkage of the fabric can be calculated using the following formula: Percentageshrinkage=Originallength−FinallengthOriginallength×100%

Dimensional stability can be defined as the ability of a material or substance to maintain its original shape for a certain period of time and under specific conditions such as temperature, humidity and pressure, among others. (Fano et al., 1992, Faria et al., 2008).

For finished garments, dimensional stability is considered to be of primary importance. Due to relaxation process, a fabric may show shrinkage in some dimensions, allowing the distortions and strains exerted on the fabric during manufacturing and processing to be released, allowing the fabric to adopt a relaxed configuration that is stable (Kalkanci & Kurumer, 2015). Shrinkage is a cumulative result of a variety of factors, including machinery effects, dyeing, finishing, and relaxation. After dry-cleaning or washing, garments made from fabrics that has no dimensional stability can change shape, which is unacceptable for users (Anupreet & Roy, 2016). Kalkanci et al. studied the use of a feed-forward back propagation NN in order to estimate dimensional measurement properties of T shirts developed by using interlock and single jersey fabrics (Kalkanci et al., 2017).
