AS 2001.5.7:1986 (R2016)

Describes a dry cleaning procedure, using a commercial dry-cleaning machine, for the determination of dimensional change of fabrics and garments after dry cleaning in perchloroethylene. It comprises a process for normal materials and a process for sensitive materials.

Scope

This standard sets out two dry-cleaning procedures using a commercial dry-cleaning machine for the determination of dimensional change of fabrics and garments after dry-cleaning in perchloroethylene. One procedure is for normal materials and involves the use of water and surfactant in conjunction with the perchloroethylene, the other is for sensitive materials and involves a strict limitation on the amount of water used and a less severe treatment of the specimens.

Very sensitive materials, which can only be cleaned when special precautions are taken, are excluded from the scope of this standard. These materials are those which will not withstand dry-cleaning even according to machine method for sensitive materials. Examples of very sensitive materials are: polypropylene, elastodiene, PVC, polyester 'Holofil' and glass. Examples of sensitive materials are many woollen knitwears, fur fabrics, crêpes, open-set, loose-spun wool fabrics, some loom-finished fabrics, boucle's, cloque' fabrics, pure silk and some silk blend fabrics, angora, acetate, acrylic, protein (regenerated), cuprammonium rayon, suede leather and some fire retardant finishes.

Normal materials are those that can be dry cleaned satisfactorily by a recognised efficient dry cleaning
process such as the machine method for normal materials specified in AS 2001.5.7.

NOTE: These materials may be identified by means of preliminary subjective tests in the solvent.
