The shrinkage rate measures the degree of shrinkage in fabrics, which is the result of the fabric freely contracting in water in a completely relaxed state during the washing cycle of a drum washing machine. Not only does the shrinkage occur in pre-dyed and finished fabrics and garments during relaxed washing, but it also happens in newly knitted blanks when they are soaked in water in a completely relaxed state, resulting in dimensional shrinkage, known as shrinkage. The shrinkage process of knitted fabrics during water washing or relaxation treatment in water is a combined effort of fiber shrinkage, yarn shrinkage, and fabric structure shrinkage.

Fiber Shrinkage

In spinning, fiber stretching (chemical fibers), weaving, and processes with high tensile forces, fibers elongate due to external stretching and form internal stresses within the fibers. The drying action under tension and the cohesive forces between fibers, as well as the interlacing resistance between yarns, temporarily fix this elongation and internal stress. When treated with water or steam, water molecules weaken the intermolecular forces between the fiber macromolecular chains, lowering the energy barrier for the chains to retract. Under the influence of internal stresses, the fibers will shrink. Long fiber fabrics, yarns with low twist, and regenerated cellulose fiber fabrics are prone to elongate due to external stretching during wet processing (such as scouring and dyeing), resulting in significant shrinkage. Cotton knitted fabrics, if processed with a relaxed method during scouring and dyeing, will not experience stretching, leading to minimal shrinkage due to fiber properties. However, if processed with high tension, significant fiber shrinkage can occur. It is crucial to note that fiber deformation caused by external stretching is difficult to recover due to the cohesive forces between fibers and the interlacing resistance (loop-to-loop junctions) between yarns. Therefore, control over the external stretching forces during the scouring and dyeing process of cotton knitted fabrics should be emphasized.
