|Title:||Structure and determinants of fibre strength in native cotton|
|Authors:||Moharir, A V|
|Abstract:||Literature on the current status of the supramolecular structure of native cotton fibre is briefly reviewed and discussed in the light of experimental data on physical properties and X-ray orientation parameters of the four cotton cultivars grown at different locations during 1992, 1994 and 1995 crop years in India. It is observed that the supramolecular structual parameters and true spiral angles, frequency of extinction bands and the morphological structure such as convolution angles remain practically invariant for a variety with the change in location and latitude of the place of growth of cotton varieties. The rate of cellulose synthesis both within and between varieties of cotton varies with the place of growth. It has been visualized that besides the length and fineness of cotton fibres, a major contribution to strength of fibres must be coming from the rate and amount of cellulose synthesized, molecular chain length-to-width ratio and its molecular weight distribution (MWD) within the matrix of the fibres during development. It is suggested that cotton breeders must use these three parameters to select and screen cotton genotypes in hybridization programs for evolving newer strains with higher tensile strength of fibres.|
