Complete Specification Accepted, 18th May, 1889
I JEAN CHRISTIAN NEYRET of 23 Boulevard de Strasbourg Paris, France, Manu-
facturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to means of giving to fabrics woven with warp and weft an
elasticity like that of knitted fabrics, by a special treatment which I will describe.
The fabric preferably of a ribbed kind, is gathered into rope form and passed for
nearly an hour between rollers revolving in a soap bath at a temperature of about 50° C.
This has the effect of narrowing the web, rendering it elastic and supple. The fabric
is then similarly treated in a bath of soda solution about 10 per cent. strength, so as
to entirely remove the soap which would affect the dyeing, and it is thoroughly rinsed
in hot water. The web, still moist, is fixed by heat, either by plunging it in boiling
water or by exposing it to steam. As the fabric thus treated could not be thoroughly
singed because the flame would not reach the bottom of its furrows, it is better that it
should be singed before being treated as above described. After the treatment the
fabric may be dyed. Woollen fabrics of almost any kind may be thus rendered
elastic, but those made from carded wool, especially for their warps, are to be
preferred.

page_text: I, JEAN CHRISTIAN NEYRET of 23 Boulevard de Strasbourg Paris, France, Manu-
facturer, 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 :-
My invention relates to means of giving to fabrics woven with warp and weft an
elasticity like that of knitted fabrics, by a special treatment which I will describe.
The fabric, preferably of a ribbed kind, is gathered into rope form and fulled by
passing it for nearly an hour between rollers revolving in a soap bath at a temperaturo
of about 5°C. This has the effect of narrowing the web rendering it clastic and
supple. The fabric is then similarly treated in a bath of soda solution about
10 per cent. strength, so as to remove most of the soup which would affect the dyeing,
and the soap and soda are then thoroughly removed by rinsing the fabric in hot water.
The fabric still moist is fixed by heat to its narrowed width, either by plunging it in
boiling water, or by exposing it to steam. As the fabric thus treated could not be
thoroughly singed because the flame would not reach the bottom of its furrows, it is
better that it should be singed before being treated as above described. After the
treatment the fabric may be dyed. Woollen fabrics of almost any kind may be thus
rendered elastic, but those made from carded wool, especially for their warps, are to
be preferred. Although I have mentioned a soap bath as that which may be employed
for fulling the fabric, other baths may be used which have a similar effect in gathering
it in to a narrower width.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The manufacture of elastic fabric by fulling woven fabric in a soap or equivalent
bath so as to gather it into a reduced width and then fixing it at the reduced width
by heat, substantially as described.
