| Abstract | ||||
| The maturity of cotton fibres could be assessed by making use of three new parameters namely mean per cent of absorbed NaOH(18 %), cotton fibre compression modulus, and convolution frequency. These three parameters are obtained when a constant weight of loose cotton fibre is immersed in 18% NaOH solution for 15 min. at room temperature and squeezed under a load of 4 kg for 5 minutes, then weighted. The compression modulus is obtained when the same sample is subjected to compression, while the convolution frequency was measured by optical microscopic method. It was found that fibres which are considered mature show high absorbtion for NaOH, low compresstion modulus and of high convolution frequency. The opposite holds good for cottons of low maturity. | ||||
