Fabric Shrinkage Rate Test; Shrinkage rate refers to the percentage that fabrics’ size presents shrink when washed or soaked, which is also an indicator of measuring the degree of fabric shrinkage. The level of fabric shrinkage rate is one of the criteria to measure product quality.
This test method covers the procedure for evaluating shrinkage, in both wet and dry conditions, of woven, knitted and nonwoven backing fabrics designed for use in the manufacture of pile yarn floor coverings. Determination of carpet backing shrinkage was previously contained...
ASTM's textile standards provide the specifications and test methods for the physical, mechanical, and chemical properties of textiles, fabrics, and cloths, as well as the natural and artificial fibers that constitute them.
Shrinkage Test of Fabric Shrinkage: Shrinkage is the process in which a fabric becomes smaller than its original size, usually through the process of laundry. Cotton fabric suffers from two main disadvantages of shrinking and creasing during subsequent washing.

Shrinkage is a change in dimensions across the length and width of the fabric after washing, usage and when exposed to relaxing of fabrics. Mainly shrinkage is of two types one is minus shrinkage and other is plus shrinkage. Skew (twisting of the vertical grains) is also observed along with shrinkage.
First, Let's talk about what causes shrinkage on fabrics. Shrinkage on fabric is mainly due to yarn swelling and the result crimp increase during washing in the case of cotton fabrics. Yarn swelling percentage is more in polyester cotton blending yarn. There are different types of shrinkage that make a fabric shrink am
The textile fabric has a common feature that it shrinks in wet processing. Shrinkage means the length of the fabric gets shorten after wash. So prior to cutting fabric for bulk production, you must check its shrinkage percentage in washing. The shrinkage percentage needed to add to the production pattern.
Shrinkage Template Scale, suitable for all shrink testing standards. Shrinkage Template Scale complies with AATCC 135/150/160/179, BS EN 3759, ISO 3759, etc. Welcome to contact us if you have any problems about fabric shrinkage test method.
Haven’t seen their product standards in years but I used to work in quality/technical design at Lands’ End and the fabric shrinkage standards varied by fabric type. 3% for a cotton knit seems really tough to me. My memory of it was closer to 5%. 2-3% is more of a woven number. And the shrinkage was calculated after each of 3 washes in the lab.
