70—PROCESSING SOLVENT-DEGREASED WOOL

Abstract
Experiments comparing the processing of solvent-degreased wool with that obtained by soap–soda scouring in several plants are described; it is shown that card and comb production rates considerably higher than normal are possible using solvent-degreased wool and a higher combing tear and a better top can be produced. At normal processing rates, the solvent-degreased wool gives 2 to 3% lower loss during carding and combing, much lower nep content, and much less fibre breakage. There is also a greater yield of clean wool from the solvent-degreasing method.
