Domestic Laundering Dimensional Change
topic
Dimensional change after domestic laundering places marked fabric specimens through standardised machine wash and tumble dry cycles at defined temperature and mechanical action settings, measuring length and width changes after conditioning and calculating percentage shrinkage or growth in warp, weft, course, and wale directions.
Role
Provides the shrinkage data that determines care label recommendations under ISO 6330 and AATCC 135 protocols, enabling retailers and brands to guarantee size retention for consumer garments throughout the labelled number of wash cycles.
