• 1. Rotting resistance of cotton, sun hemp, Italian hemp, sisal, manila and coir twines immersed in Cochin backwater has been determined. 2. The values of rotting coefficient K in TAUTIS formula log T/T0-T=-(K log e)+ Const. were calculated from the results obtained by the experiments and it was confirmed that the value of K is inversely proportional to the diameter of twines dipped. The values of K worked out are as follows: and Higher the value of K, the rotting would be quicker. 3. Number of days N till a twine loses half of its original breaking strength is proportional to the diameter of the twine dipped in water, i. e. N=αD. Where a is constant and when D the diameter is in mm, N=6.50 D for cotton =5.75 Dfor sun hemp =2.55 D for Italian hemp =6.00 D for sisal and =7.40 D for coir.
