WALTER ALFRED BARLOW, of 0, St. Paul's Churchyard, London, Patent Agent
and Engineer. "IMPROVEMENTS IN PROCESS FOR CHINEEING THREADS OF FIBROUS
MATERIAL BY DYEING." A communication from abroad by Monsieur Edouard
Tavernier, of Paris, France, Director of "La Société en Participation du Chinage
par Teinture."
Up to the present time when it has been desired to chinee thread by dyeing, the
operation has been performed by means of ligatures placed at certain intervals on
the skeins. This manual process, besides being very costly, is the only one which
has given good results; all other processes that have been tried have had this.
inconvenience, they allow the dye to pass into the reserved parts and give no
practical result. These processes are so costly and defective that up to now
preference has been given to the printing by impression for producing stripes
on thread. It has been essayed to apply to thread the system invented by
Mr. Bentayoux for chineeing either combed or carded slivers before spinning, which
is characterized by the following points :-
1st. The binding of threads at certain intervals between wood or metal pieces of
such shape that the matter to be chineeed is surrounded.
2nd. The employment of fixed male and female grates to produce this effect.
3rd. The disposition of the matter of the prepared fibrous material around the
female grates in such wise that the surface is entirely covered by a uniform layer
of matter to be chineeed.
4th. The application on both sides of the female grate of a male grate, the bars
whereof correspond exactly to those of the female grate.
5th. The stationary vertical arrangement in the bath of the combined male and
female grates furnished with prepared fibrous material.
6th. The circulation of the "mordant" bath and of the dyeing bath across the
so formed and furnished combined grates which remain immovable.
7th. Central tightening or compressing arrangement.
These several principles, which constitute the Bentayoux process, have received a
new application which is the object of this Invention. Preference is given to the
injection of the dye on the frames in such wise that it penetrates into the intervals

between the bars, and dyes in its passage the unreserved parts. For this the frames
are laid down in such wise that the fibrous material is horizontal. The "mordant
is applied in the same manner, and thus is avoided the inconveniences produced by
immersion.
Everything which is explained in the foregoing description is equally applicable
to this class of dyeing for wool, cotton, or other textile materials.
The frames are constructed in the same manner, but the distance between the
bars is lessened.
The female frames, aro covered with thread by the process described for combed
wool, but instead of covering the whole surface with the same thread a certain
quantity of threads are placed close together. For this a machine is provided
similar to that specified by Mr. Bentayoux in his Specification, but in which
is substituted for the combed sliver a certain quantity of closely packed
threads.
The female frame when entirely covered with threads is placed between two male
frames, and the whole is placed vertically in the bath and pressed by the plate, as
has been described.
