The method of manual separation should be used whene
23、ver possible, since it generally gives more accurate results than the chemical method. It can be used for all textiles whose component fibres do not form an intimate mixture, as, for example, in the case of yarns composed of several elements each of which is made up of one type of fibre, or fabrics
24、in which the warp is of a different type of fibre from the weft, or knitted fabrics capable of being unravelled and made up of yarns of different types. In general, the methods for quantitative chemical analysis of ternary fibre mixtures are based on the selective solution of the individual componen
