27、g and drying procedures in this method are similar to the International Standard ISO 6330, Textiles Domestic washing and drying procedures for textile testing using a Type B washer, top-loading, agitator type.1. PURPOSE AND SCOPE1.1 This method determines the dimensional change of textile fabrics or
28、 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 restoration procedures are included as follows:1.2.1 Washing Procedur
29、es2I Low temperature (40C), low mechanical action, synthetic detergentII Medium temperature (50C), low mechanical action, synthetic detergentIII Medium temperature (50C), moderate mechanical action, synthetic detergentIV High temperature (70C), moderate mechanical action, synthetic detergentV Cold t
30、emperature (20C), low mechanical action, detergent3VI Cool temperature (30C), low mechanical action, detergent3VII Medium-high temperature (60C), moderate mechanical action, synthetic detergent.1.2.2 Drying ProceduresA Drip dryB Flat-bed pressC Flat dryD Line dryE Tumble dryF Tumble dry without heat
31、.1.2.3 Restoration Procedures1 Tension presser2 Knit shrinkage gauge3 Hand iron.1Experience has shown that most relaxation shrinkage occurs in the first wash, two additional washes usually being sufficient toeffect complete relaxation shrinkage.2Any other combination of temperature, mechanical actio
32、n, bleach and detergent may be used, but must be reported.3It is recommended that a cold water or liquid detergent be used.11.3 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 con
33、sists of a washing, drying and, if necessary, a restorationprocedure. For example, 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,
34、depend upon the choice of test conditions used.1.4 The seven washing tests 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
35、materials. Three procedures are specified for determining the dimensional restorability 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 textil
36、earticles. This method is also applicable to certain nonwoven fabrics. For 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 n
37、ot be suitable for use with certaintypes of fabrics such as those of open construction 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
38、required to be minimal (e.g., as in hand washing), CAN/CGSB-4.2No. 25.1 should 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 sa
39、fety aspects associated with its use. Anyoneusing this method has the responsibility 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
40、 is washed in an automatic domestic washing machine. Excess water is removed 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 spe
41、cimens in the length andwidth directions, or in appropriate locations on garments, are measured before and after laundering, and thepercentage dimensional change in each direction is calculated.3.
