The effect of alkali on acrylic fibers has been studied, particularly with reference to 5% w/v NaOH used in the quantitative analysis of wool with acrylics. The discrepancies observed in the results are analyzed. An alternative modified method suitable for quantitatively separating acrylics from wool using DMF has been standardized to overcome the discrepancies observed in the alkali method. Application of this method' to commercial blend samples of wool with varying contents of acrylics as well as extension to other relevant tests is also discussed.
