AATCC Test Method 150-2018t, Dimensional Changes of Garments after Home Laundering
Developed in 1977 by AATCC Committee RA42; editorially revised and reaffirmed 1979, 1984, 1992; editorially revised 1983, 1985, 1989, 1990,1991,1996, 1997, 2004, 2005, 2006, 2008, 2016; revised 1987, 1995, 2001, 2003 (with title change), 2010, 2012, January 2018, November 2018; reaffirmed 2000. Related to ISO 3759.
Although this method calls for measurement of dimensional changes in un-seamed areas of garment specimens, results may be affected by garment construction, tensions, sewing threads or trims in addition to fabric dimensional change. An option is also provided for measuring dimensional change between or along garment seams.
Standard laundering procedures remain consistent to allow valid comparison of results. Standard procedures represent, but may not exactly replicate, current consumer practices, which vary over time
and among households. Alternate laundering procedures and machine parameters may be found in AATCC LP1, Laboratory Procedure for Home Laundering: Machine Washing, AATCC LP2, Laboratory Procedure for Home Laundering: Hand Washing and ISO 6330, Textiles - Domestic washing and drying procedures for textile testing.
1. Purpose and Scope
1.1 This test method is for the determination of dimensional (length and width) changes of garments when subjected to home laundering procedures. Four washing temperatures, three agitation cycles, and four drying procedures provide standard parameters to represent common home care options.
1.2 This method may not be applicable to garments made of certain stretch fabrics.
