Woven and nonwoven blankets were compared before and after five launderings. Laundering was associated with enhanced thermal insulation effectiveness, which was related to structural changes. Both woven and nonwoven blankets provided improved thermal insulation after laundering, with the most significant improvements in thermal insulation occurring among the nonwovens. With respect to dimensional stability, structural changes, and thermal insulation, the nonwovens were found to be equivalent or superior to the wovens after five launderings.
