1 Scope This Part of GB/T 19981 specifies a method for assessing the performance of fabrics and garments after drycleaning and finishing according to procedures specified in GB/T 19981. This Part is applicable to the identification of fabric and garment properties which may change on drycleaning and finishing. The current standards for assessing such changes are provided in this Part; other properties which are also important, but for which there are no standards which provide methods of assessment, are indicated in Appendix A, together with advice on how to proceed on their assessment. It is recommended that comments on these should be included in the test report (see Chapter 8 and Appendix B). For the assessment of dimensional change, this method refers to primary drycleaning and finishing; if the progressive variation is required, this method will be repeated as specified, usually not more than 5 times. 2 Normative References The following normative documents contain provisions which, through reference in this Part of GB/19981 constitute provisions of this Part. For dated reference, subsequent amendments (excluding amending errors) to, or revisions of, any of these publications do not apply.

The first test specimen is used as a control to indicate the original condition, and does not undergo any drycleaning and finishing treatment. The second test specimen is subjected to a drycleaning process using commercial equipment involving a two-bath cleaning, rinsing, centrifugal extraction, tumble drying and appropriate finishing. An assessment of dimensional, color and other changes is carried out after cleaning and finishing by comparing the second test specimen with the first test specimen. The assessment determines whether or not the item is regarded as dry-cleanable in the process selected. If a retest in a more sensitive process is necessary, a third test specimen is required.
