Improvement in the Process of Treating Textile Fabrics and
Manufacturing Bagging from Jute Butts.
We, ANDERSON GRATZ and BENJAMIN GRATZ, Manufacturers and Merchants, of
the City of St. Louis, in the State of Missouri, one of the United States of
America, 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:-
Our Invention relates to an improved method of treating textile fabrics, such, for
instance, as bagging manufactured from jute butts and other fabrics, and our
Invention consists in applying to the fabric a chemical solution, and then rolling or
baling the fabric into bundles while yet damp with the solution whereby the
chemicals act upon the fabrics and bleach them.
In carrying out our process we take a solution consisting of suitable chemicals
and water, say two to three pounds of the former to seven or eight pounds of the
latter, and apply it to the fabric, preferably while the latter is on the calender.
Any suitable chemical may be used, as for instance, borax, soda, alum, chloride
of sodium, and still other chemicals that would have the desired effect.
After the solution is applied the fabrics are formed into bundles or rolls while yet
damp with the solution, and stored away in this damp condition, when a chemical
action takes place in the mass, which effects the bleaching of the fabrics, and renders
them whiter than they would be if the same solution were applied and the fabrics
dried before being formed into bundles or rolled up.
Not only is the result the bleaching of the fabrics, but it also renders the fabrics
fire-proof, and makes them softer and more pliable, and thus adds also to their value.
We are thus enabled to produce a very much higher grade of fabric than it has
been possible heretofore to produce from the same quality of material.
As an example of a suitable solution per yard of the fabric, we would state that
two and a half pounds of chloride of sodium, dissolved in seven and a half pounds of
water, has been found to give good results.
This Invention is particularly applicable to the manufacture of bagging from jute
butts, and will make the bagging far superior to that heretofore made from this
article, in that it is lighter in colour, and much superior in appearance to the old
article.
By applying the solution while the goods are on the calender, the solution does not
come in contact with the spinning and weaving machinery, which would cause them
to rust, and by applying it while the goods are on the calender, and just before being
rolled up, a very thorough and even distribution of the chemical through the goods is
obtained. As before stated, the rolls are stored away as they come from the calendar,
and in a damp condition, produced by the application of the chemical, and the result
is that a chemical action takes place in the tightly rolled goods, which very materially
improves the colour of the article, and adds much to its value, but practically nothing
to the cost of its production.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1. The improved process of treating textile fabrics, consisting in applying a chemical
solution to the fabrics and then baling or rolling the fabrics into bundles, and placing
the bundles away in this damp condition, substantially as and for the purpose
set forth.
2. The improved process of manufacturing bagging from jute butts, consisting of

fabric, and then winding the fabric into bundles while still damp, substantially as
set forth.
3. The improved process of making bagging from jute butts, consisting in applying
a solution of chloride of sodium, and then storing the fabrics. away in mass, while
damp, and allowing a chemical action to take place for the purpose of bleaching the
fabric, substantially as set forth.
