Abstract

'Movement' is the term applied to shrinkage or swelling of seasoned wood in service due to fluctuations in atmospheric conditions. In this paper experimentally determined movement values of 6 Indian species between 32 and 93 per cent R.H. are reported. Amongst the limited number of species studied, teak showed the smallest movement value whereas Eucalyptus showed the largest movement value.

Abstract

The indigenous woods for weft-pirn making have been selected on the basis of available physical, mechanical and wood-working properties. In this report, physical, mechanical and wood-working properties of Eucalyptus hybrid are compared with those of the timbers given in IS: 4417-1967. Data on actual manufacturing trial indicated that Eucalyptus can be utilised for weft-pirn making. Weft-pirns made from Eucalyptus from two different sources appeared comparable with those made from white-cedar and resistance to moisture was within permissible limits. Sawing and seasoning technique for Eucalyptus wood are also discussed.
