Analysis of cotton fiber maturity. I. x-ray study of phase transformation in various cottons


  • Paper presented at the 14th Joint Technological Conference of ATIRA, BTRA, and SITRA, held at SITRA, Coimbatore, India.


An x-ray diffraction technique is described for the determination of the extent of conversion of cellulose I to cellulose II lattice in partly mercerized cottons. This technique has been applied to obtain the degree of phase transformation, after subjecting various cottons to swelling in 12% (w/w) NaOH at 65% R.H. and 27°C. For the various cottons studied, a direct relationship is found to exist between fiber maturity and the untransformed cellulose after swelling.
