	abstract = {Wool from lines of Romney sheep selected for high and low staple  
strength and a randomly selected control line were processed into worsted yarn  
for handknitting (ewe hogget fleeces) and semi-worsted yarn for carpets (adult  
ewe fleeces).  Separate lots of wool were created for each line with the fleeces  
chosen to ensure that the lots had similar mean fibre diameter, staple length 
and medullation.  Hogget wool yarns were knitted into panels and the adult ewe  
wool yarns were tufted into carpet. 
 
In the hogget wool processing trial, increased staple strength was associated  
with greater mean length after carding and higher combing yields, with small  
improvements in yarn tenacity and in knitted panel abrasion and pilling test  
results. 
 
The adult ewe wool processing trial also produced a significant difference in  
length after carding.  At high spindle speeds the high strength line performed  
better in spinning, producing fewer "end-breaks". 
 
The trials indicate there are real advantages for worsted and semi-worsted  
processing and product performance, warranting premiums for high strength  
wools.
