some Indian wools and the efficiency of its removal on woollen card are
reported. It is observed that only the medium burry wools having up to 6%
vegetable matter can be brought to an acceptable level by mechanical removal of
vegetable matter on the woollen card.</span>

re-extruded into filaments to examine the feasibility of industrial processing
of waste nylon. Although some degradation occurred during extrusion,
satisfactory re-extrusion of both the nylons could be accomplished. Further
re-extrusion caused deterioration in the characteristics of the samples, the
deterioration being much more pronounced in the case of nylon 6.6. It follows
that nylon 6 (but not nylon 6.6) can be re-extruded to produce good usable
textile filaments and if the discoloration problem could be overcome,
re-extrusion of nylon 6 could be a practical proposition.</span>

deniers have been evaluated. On blending with wool, the polypropylene fibre
produces a yarn with unique properties suited for knitwear.</span>

maximum exhaustion of the dye bath takes place at 100°C after 90 min. The
fastness properties of the dyes on polyester fibres are compared with respect
to the position and the nature of the substituent.</span>
