PROVISIONAL SPECIFICATION.
A New or Improved Process for Improving the Appearance of
Textile Fabrics.
EDWARD LODGE, of 94, Bradford Road, Huddersfield, Yorkshire, Teacher of
Dyeing, and JOE FROST, of Storth Mill, Moldgreen, Huddersfield, Yorkshire,
Chemical Manufacturer, do hereby declare the nature of this invention to be
as follows:-
We take a solution of hydroxylamine hydrochloride, sulphate or acetate, and
cause the goods to pass through this solution. The operation may be carried out
by means of hand labour or any mechanical contrivance well understood by
Scourers, dyers or finishers. The strength of the solution being regulated by the
requirements of each class of goods.
We claim that by this treatment the goods are greatly improved in appear-
ance, more especially white goods or goods containing white our process removing
the soiled appearance frequently acquired by textile fabrics during the process
of scouring, dyeing or finishing.

A New or Improved Process for Improving the Appearance of
Textile Fabrics..
We, EDWARD LODGE, of 94, Bradford Road, Huddersfield, in the County of
York, Teacher of Dyeing, and JOE FROST, of Storths Mill, Huddersfield, aforesaid,
Manufacturing Chemist, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
This invention relates to a new or additional process or treatment for improving
the appearance of textile fabrics, especially fabrics which are wholly white, or
contain white, the object of our invention being to remove the soiled appearance
or yellowish tint or tone commonly acquired by textile fabrics, or the white or
light colours in them during the processes of scouring, steaming, or finishing,
and restore the whiteness or clearness and purity of the white or light colours.
For the purpose of our invention we take a solution of hydroxylamine hydro-
chloride, or hydroxylamine sulphate, or oxalate, acetate, nitrate, tartrate, or cit-
rate. which may be produced by addition of the acids to the free base; or by.

The fabrics to be treated are caused to pass through the aforesaid solution
either by hand labour or by any mechanical contrivance well understood by
Scourers, dyers, or finishers; or the fabrics may be sprayed or brushed on the sur-
face with a solution of the above salts. The strength of the solution is regulated
according to judgment and the requirements of each class of goods to be treated.
By passing textile fabrics through or treating them with the aforesaid solution,
they are greatly improved in appearance more especially in the case of white
fabrics or fabrics containing white, the soiled appearance or yellow tone or tint
acquired by the fabric or the white in the fabric during the processes of scouring,
steaming, or finishing, being removed. The bath must not be allowed to become
alkaline, but if it should become alkaline, the efficiency of the solution may be
restored by neutralising the alkali with an acid.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is:
The use, in the treatment of textile fabrics to improve their appearance, of a
solution of hydroxylamine hydrochloride, or hydroxylamine sulphate, oxalate,
acetate, nitrate, tartrate, or citrate produced by addition of the acids to the free
base, or by double decomposition, the fabrics, in a process subsequent to the scour-
ing, steaming, or finishing, process, or processes, being passed through the said
solution or sprayed or brushed on the surface therewith, substantially as and for
the purposes described.
