Improvements in the Manufacture of Waterproof Fabrics.
I CHARLES HENRY ARNOLD of 67 Shakespeare Street, Plymouth Grove
Manchester, in the County of Lancaster, Manager, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :—
The object of this invention is to produce a waterproof fabric or combination of
fabrics suitable for the manufacture of travelling and other bags, satchels, and
the like, also for making or covering travelling trunks, and for making wear
resisting and waterproof garments for sporting and other purposes.
For the purposes of my invention I take two woven fabrics of suitable material,
say for example, for the exterior, strong canvas of cotton, jute or other such fibre
according to the use to which the finished material is to be put; and for the interior,
a thinner fabric, say for example, twilled cotton or other suitable woven material.
These two fabrics being dyed either the same color and shade (say brown) or
preferably the lining of a somewhat lighter shade, I unite them together by
applying to the inner surface of one or both of them (by brushing, spreading or
otherwise) a coating of an adhesive material or composition such as is soluble in
water or spirit but not affected by heat, and not in itself waterproof, such for
example, as paste made from flour, or other farinaceous material, gum, animal glue
or other suitable matter, avoiding the use of india rubber, gutta percha, or materials
of a pitchy or tarry nature, and liable to dissolve or run when subjected to heat.
This adhesive material or composition is mixed with color to correspond with
the color of the fabrics so that should any of the material or composition ooze
through to the surface it will not cause a mark or stain thereon. The two fabrics
thus prepared are pressed together between rollers or otherwise to cause them to
adhere perfectly together, and are allowed to dry thoroughly.
The combined fabric is not in this stage waterproof, and exposure to rain or
damp would be liable to dissolve the adhesive material or composition, and more or
less separation of the two fabrics would result. To prevent this, and to render the
combined material waterproof or water-repellent, I apply to both surfaces by
brushing, rubbing or otherwise (without the application of heat or solvent), a
coating of wax or stearine mixed or impregnated with coloring matter,
corresponding with the color and shade of the cloth or fabric, the surface being
then well brushed to rub in the wax or stearine and to remove all the superfluous
material; and the combined fabric is then perfectly water repellent and is ready
for use.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
First, The method of manufacturing combined waterproof or water repellent
fabrics for the purposes above stated substantially as herein before described, and
Secondly, I claim as a new manufacture waterproof or water-repellent fabrics
manufactured as hereinbefore described.
