PROCESS OF MAKlNG UTE B'AGGING.

3 SPECIFICATION forming part ofLetters Patent No. 432,401, dated July 15, 1890.

Application filed F bruary 18,1890. Serial No.-340,97. (No specimens.) 7 7 To all whom it'may coir/cent;- Bet known that we, ANDERSON GRATZ- and BENJAMIN. GRATZ, both of the city of St.

Louis,in the State of Missouri, have invented F Process of Manufacturing Bagging from Jute much inoredesirable; The bagging made duced and placed upon the market ,Very

produce'a bagging from jute butts which will be, far superior to the bagging heretofore made from this article, in that it is lighter in old article. 7

It has been common for many years to treat fabrics with different chemicals, including ing them fire-proof. The only methods of treating' 'such fabrics, so far as we are aware, has beenby steepingfor boiling the fabrics in a chloride of sodium or other chemical solution;'"but"'this*method would be wholly-impracticable in the manufactureof bagging from jute butts, owing to the great bulk of the material to behandled and the very cheap way in which the goods must be made. "The total expense of manufacturing bagging from jute butts does not" exceed one cent per not exceed three-quarters of one'cent per pound, and if the bagging were steeped or saturated with the chloride of i sodium it would cost at least one-quarter of onecent per rially to the cost of the product as to interhas-been found to give good result? tically made. l p p In practicing our invention-we use chloride of sodium, and toavoid thissoaki'ng orsteep- 'ing of the product We have conductedv many experiments in applying the sol'ution ofychloride of sodium more different processesof manufacturing this coarse bagging' from jute butts, and after many-trialslhavefdiscovered and adopted the planlot' 's rinkling the cloth with a solution-of chlorid f sodium, being tion when it is rolled into fight pmk gput away in a, damp condition. WVe p to apply the solutioiito the goods after, w

the r goods'are on the ccalender and just -before being rolled up a very thoroughgan'd even distribution of the chloride :of sodium through the goods is obtained. As before 75 I stated, the rolls are stored away as-they come", a 7 from the calender in a damp condition, produced by the application of the chloride-of sodium,and the -result is that achemica l actiontakes place in the tightly-rolled; goods,f8o which very materially improveskthe color of, c the article and adds much-to its value, but practically nothing to the cost of itsfproductionl I v We are thus enabled, to produce a very much higher grade ofbagging than ithas been possible heretofore to produce'from jute butts.- i l I As an example of a suitable solution per;
