摘要

Efforts have been made to modify the existing standard method IS: 2369 - 1967 which is meant for the determination of sinking time of well-scoured cotton fibres. A fibre container has been prepared to achieve standard dimensions in the fibre mass in cake form at the time of sample preparation and testing. Minute holes are made at the bottom and the lid of the container and the fibre cake is kept inside it to come in contact with water taken in a specially fabricated glass trough. Holes with diameters 0.25, 0.5 and 1.0 mm have been studied to assess their effect on sinking time. It is observed that the fibre container provided with holes having 0.5 mm diameter performs very effectively for the determination of sinking time of partially scoured cotton fibres. This method is also found to be suitable for well scoured cotton fibres. As this method is suitable for the determination of sinking time of cotton fibres scoured to any extent, it may be considered by the standards organizations for introducing it as a standard testing method following the necessary protocols.
