PURPOSE AND SCOPE1.1 This me
30、thod determines the dimensional change of textile fabrics or garments, likely to occur in domesticlaundering procedures. The fabric specimen or garment is subjected to an appropriate combination of specifiedwashing, drying and restoration procedures.11.2 Seven washing, six drying and three restorati

35、etworking permitted without license from IHS-,-,-1.3 Before using this method, the combination of procedures suitable for the particular item to be tested must be selectedto arrive at the appropriate test. A complete test consists of a washing, drying and, if necessary, a restorationprocedure. For e
36、xample, Test IIB1 means that the textile material has been washed at 50C with low mechanicalaction, and synthetic detergent, dried by flat-bed press and restored by tension pressing. The final result obtainedwill, of course, depend upon the choice of test conditions used.1.4 The seven washing tests
37、specified vary in severity of operating conditions and correspond in their essentials toprocedures commonly used in home laundering. The six drying procedures specified provide appropriate methodsfor drying different textile materials. Three procedures are specified for determining the dimensional r
38、estorability ofmaterials after washing and drying for those textiles that may be restored by ironing or wearing.1.5 This method is suitable for use with woven or knitted fabrics and also with garments and other made-up textilearticles. This method is also applicable to certain nonwoven fabrics. For
39、nonwovens, the principal directions ofmeasurement shall be machine direction and cross direction (perpendicular to the machine direction). Nonwovenfabrics are not usually subjected to restoration procedures. This method may not be suitable for use with certaintypes of fabrics such as those of open c
40、onstruction or delicate nature. Mechanical action is the factor mostresponsible for fabric distortion during washing and this must be considered when choosing the procedure to beused. Where the amount of mechanical action is required to be minimal (e.g., as in hand washing), CAN/CGSB-4.2No. 25.1 sho
41、uld be used for dimensional change.1.6 The testing and evaluation of a product against this method may require the use of materials and/or equipment thatcould be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyoneusing this method has the respo
42、nsibility to consult the appropriate authorities and to establish appropriate health andsafety practices in conjunction with any applicable regulatory requirements prior to its use.2. PRINCIPLE2.1 A garment or fabric specimen is washed in an automatic domestic washing machine. Excess water is remove
43、d andthe specimen is dried by one of the specified procedures and, where necessary, subjected to a dimensionalrestoration procedure.2.2 For determining the dimensional change, the reference dimensions marked on the fabric specimens in the length andwidth directions, or in appropriate locations on ga
44、rments, are measured before and after laundering, and thepercentage dimensional change in each direction is calculated.3.
