A simple nondestructive method for the quantitative analysis of textile fiber blends has been sug gested. The method requires measurement of moisture regain of the blend and its component fibers. Experimental studies have been made with cotton-viscose, polyester-wool, and cotton-wool blends. For comparison, blends have also been analyzed by known chemical methods. It has been found that, in all cases, moisture regain of the blend can be obtained by linear combination of the moisture regains of its constitutent fibers.
