ISO 7771 Textiles - Determination of Dimensional Changes of Fabrics Caused by Immersion in Cold Water

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 7771 testing. ISO 7771 specifies a method for determining the dimensional changes of fabrics when immersed in cold water. This test method is applicable to all types of textile fabrics, including woven, knitted and non-woven fabrics.

It can be applied to fabrics exposed to cold water without agitation during use. The sample is cut from the sample and measured after conditioning, wetted, dried under the conditions described, regenerated and remeasured. Dimensional changes are calculated in the longitudinal and/or transverse direction.

The purpose of this standard is to provide a consistent and standardized procedure for assessing how fabrics can shrink or expand when immersed in cold water. This information is important for manufacturers, quality control and consumers to understand how a textile can perform when washed or exposed to cold water.

This standard applies to textile manufacturers, quality control laboratories and anyone involved in the production or testing of textiles. It helps ensure that fabric size changes due to cold water immersion are consistent and measurable, enabling better quality control and consumer information.
