TEAZING. 
The scoured wool when dry is in a condition which necessitates its wt 
subjected to some operation that will, in a measure, open and disentangl? | 
fibres before being passed on to the scribbling machine. The technical 1°) 
for this operation is teazing or willowing. | 
This machine consists of a large skeleton cylinder or drum with ten a | 
each mounted with two rows of teeth tapering from the base to the point ‘h 
three small rollers termed “workers” fixed above the cylinder, and studded 
teeth, which work between those of the latter when the machine is in mol | 
The wool is weighed out in regular quantities and spread on the feed § net 
which carries it into the interior of the machine, where it is received by 
teeth of the main cylinder. || 
The principle of the machine is this: A large and centre drum, maki . 
from 400 to 500 revolutions per minute charged with wool, working againsl | 
turning in a contrary direction to, a series of three smaller rollers making | 
thirty to forty revolutions per minute. So that no sooner is the material fo ‘ih 
round by the main cylinder than the teeth of the workers come in contact ™ 
the felted and entangled locks, effecting a thorough separation amongst © | 
fibres. wal 
Burr Extracting.—It may either be done by chemical or by mecha! | 
means. The former process consists in steeping the wool in a solution OFT 
phuric acid and water (standing at about 9 degrees Twaddle) for about-hae | 
hour, when it is taken out, allowed to drain, and then removed to the dy in| 
room and submitted to a temperature of about 100 degrees fahr. The acd 
of the sulphuric acid is due to the fact that it absorbs the watery elements fr aff 
the substance of vegetable fibres, such as burr, leaving the carbon beh | 
During this process the vegetable matter is carbonised, whilst the horny subst!”

of the wool remains sound. to 
The mechanical contrivance for removing burrs consists chiefly in a 8° shut | 
rollers so arranged that the wool staples get opened up, the burrs loosened 80% 
they hang freely in the wool, in which condition they are knocked off whilst 
clean wool is passed out. “att | 
After the wool has been scoured it has been deprived of its natural lubri@’ | 
and is now in a dry, open condition, so that, if passed to other machines Wt dhe 
being lubricated again, parts of it would be cast off the different cylinders %) (y) 
carding machines in the scribbling processes and go to form “ fiying® 
“droppings.” ut 
Olive oil is commonly used for that purpose. tis applied either by tho | 
of a can with a T-shaped muzzle or by a machine constructed for that pup 
The wool now passes througha machine called the Fearnought, or OG! 
hook willey. By passing through it, the wool is still more disentangled oat r| 
its original conglomeration into staples, after which it passes on to the ca™ “| 
machines to be scribbled. tit 
Carding is, in one sense of the word, a continuation, on a more syste 
principle, of the separation and mixing of fibres of the wool, as it has ® | 
commenced by the teazer and Fearnought. ade! 
The carding machines are composed of a set of rollers that are StU) 
with very fine steel hooks of different shape and position to each other, a 11) 
rotation as well as the speed of the rollers is so arranged as to thor0Us iy) 
separate the fibres from each other in the first instance and rearranging det | 
position again. They will in the end become so effectively crossed and nea 
together as to produce one promiscuous mixture of uniform density throug” yy 
In scribbling there is no attempt made to lay the fibres in parallel line, | 
very opposite of this effect being designed - namely, to mix and intermingle be 
on one common but uniform system. After the wool has been reduce® , 9
