CHROME LEATHER.
The following dye-stuffs are suitable for dyeing chrome leather. The
leather after tanning, is boraxed in the usual manner and then mordanted
by drumming or paddling in a tannin solution; for dark shades 3 per
cent. gambier and 3 per cent. fustic extract (the weight being
calculated on the leather struck out after boraxing) is suitable; for
light shades 1¹⁄₂ per cent. gambier is to be recommended. The leather,
after mordanting, is fat-liquored and dyed, adding a weight of sodium or
potassium bisulphate equal to that of the dye-stuff, to the dye-bath.
The following is not by any means a complete list of the dyes which will
dye chrome leather well, but merely representative.
After the goods are dyed, they should be well washed in tepid water to
which has been added a little common salt; one pound to every three
dozen skins being a suitable amount to use. When the goods have been
washed, they are struck out by machine and are then ready for shaving,
if the operation has not been performed previous to dyeing. The skins
are afterwards nailed out flat, grain-side up, on boards, and a mixture
of glycerine and water--3 lb. of glycerine dissolved in one gallon of
water being a suitable strength--is well sponged on the grain-side; the
goods are now lightly oiled (using a good sperm, neat’s-foot or mineral
oil), before being taken to the drying room. When thoroughly dry they
are taken off the boards, and placed with layers of damp sawdust between
each skin, for a few hours in order to allow the goods to become
suitably damp for staking. The skins should now be well staked by
machine, the Haley (England), Slocomb or Vaughn (America) being good
machines for this purpose (p. 192).
After staking, the goods are “soft-boarded,” and a thin coat of a weak
linseed mucilage is applied to the skins, which are afterwards dried out
and seasoned with the following mixture:--
“Soak 10 to 15 oz. of dry egg albumen for four hours in 1 gallon of cold
water, with occasional stirring, strain off any insoluble matter and add
1 gallon of milk. A little carbolic acid (phenol) may be added to the
above if it is desired to keep the finish for more than two or three
days--1 oz. of phenol previously dissolved in a little water, added to
each gallon of the finish, being a suitable amount.” A little dye should
be added to the mixture.
After seasoning, the skins are dried out in the stove, glazed twice
round and re-seasoned with the above mixture diluted with its own volume
of water. The goods are dried out and again glazed, perched lightly, and
finally boarded up from neck to tail in order to raise the popular
straight-grain. Should the glaze be too bright the albumen solution may
be reduced to half-strength.
When the goods have been glazed they are rubbed over on the grain side
with a flannel cloth which is slightly damp with linseed oil, trimmed
up, and are ready for sale.

Titanium salts (potassium titanium oxalate and tanno-titanium oxalate)
may be employed in conjunction with the coal-tar colours for dyeing
chrome leather, with many advantages over the ordinary mordants, the
colour produced being faster to light, rubbing, fuller in shade, and
with much less tendency to “grinning.” When employing titanium mordants,
the leather should be first lightly mordanted with some tannin solution
and afterwards dyed with the titanium and dye-stuff in the same bath, in
which case only “acid” dyestuffs may be employed. If desired the goods
may be mordanted with the tannin mordant, afterwards treated with the
titanium salts, washed and dyed; in this case the dyeing and application
of the titanium mordant being carried out separately, the leather may be
dyed with either the acid or basic dye stuffs. The titanium and tannin
mordants may also be applied in the same bath.
DYEING CHAMOIS LEATHER.
The following colours dye chamois leather well, after washing the
leather in a weak soda solution, mordanting with 3 per cent. basic
chrome alum solution, and transferring to the dye-bath without washing.
Equal weight of bisulphate of soda to that of the dyestuff is added to
the dye-bath.

The leather is run in the dyestuff solution at a temperature of about
45° to 50° C. for about half an hour, and then lightly fat-liquored, if
desired, and afterwards dried.
In addition to the dyestuffs mentioned above many basic colours may be
employed after the treatment with titanium, some of these producing a
colour lake with the titanium mordants.
As regards the permanency of the various colours to light, the reader
is referred to an important paper by Mr. Lamb,[199] but in many cases
the probable permanency is indicated by a number prefixed to the name of
the colour in Roman figures, I. corresponding to the lowest, and X. to
the highest permanency. In the research referred to, about 1500 samples
of leathers dyed with coal-tar dyes were exposed to light for a series
of “periods,” each equal in actinic power to nine days of the brightest
summer sunshine. The most fugitive colours faded completely, even in the
first “period,” and the most permanent before the end of the tenth. The
prefixed numerals indicate to which of these “periods” the colour
survived.
