This British Standard describes a procedure for the quantitative removal of size and filling from cotton, viscose, or synthetic fibres, yarns and fabrics in which the adhesive is starch, a chemically-degraded starch, a vegetable gum or some other water- or alkali-soluble polymer. It is not applicable where the starch has been made insoluble, as in formaldehyde-containing finishes. The standard is not intended for use when determining small amounts of residual starch or fatty materials.
