be used again for
another lot of goods simply by adding fresh material to make up for
that absorbed by the first lot.

Loose wool and loose cotton are somewhat difficult to deal with by (p. 198)
squeezing or wringing, but the material may be passed through a pair
of squeezing rollers such as are shown in figure 24, which will be
more fully dealt with later on.

#Yarns in Hanks.#--In the hand-dyeing process of hank-dyeing the hanks
are wrung by placing one end of the hank on a wringing-horse placed
over the dye-tub, and a dye-stick in the other end of the hank, giving
two or three sharp pulls to straighten out the yarn and then twisting
the stick round; the twisting of the yarns puts some pressure on the
fibres thoroughly and uniformly squeezing out the surplus liquor from
the yarn.

#Hank-Wringing Machines.#--Several forms of hank-wringing machines have
been devised. One machine consists of a pair of discs fitted on an
axle, these discs carry strong hooks on which the hanks are placed.
The operator places a hank on a pair of the hooks. The discs revolve
and carry round the hank, during the revolution the hank is twisted
and the surplus liquor wrung out, when the revolution of the discs
carries the hank to the spot where it entered the machine, the hooks
fly back to their original position, the hank unwinds, it is then
removed and a new hank put in its place, and so the machine works on,
hanks being put on and taken off as required. The capacity of such a
machine is great and the efficiency of its working good.

Mr. S. Spencer, of Whitefield, makes a hank-wringing machine which
consists of a pair of hooks placed over a vat. One of the hooks is
fixed, the other is made to rotate. A hank hung between the hooks is
naturally twisted and all the surplus liquor wrung out, the liquor
falling into the vat.

#Roller Squeezing Machines for Yarn.#--Hanks may be passed through a
pair of indiarubber squeezing rollers which may be so arranged that
they can be fixed as required on the dye-bath. Such a pair of (p. 199)
rollers is a familiar article and quite of common and general use in
dye-houses.

#Piece Goods.#--These are generally passed open through a pair of
squeezing rollers, which are often attached to the dye-vat in which
the pieces are dyed.
