PATENT OFFICE RALPH H. MGKEE, OF JERSEY CITY, AND EARLE H MORSE, 0F NUTLEY, NEW JERSEY ART or TREATING VEGETABLE mEEs The present invention relates to the art of treating vegetable fibers, and more particularly to a process of treating a vegetable fiber to change or modify its characteristics.
Due to the limited supply and relativelyhigh price of wool, many attempts have been made to provide fibers which could be used with or in place of wool. For instance,
the resulting fibers do not carry suflicient crinkle and do carry too much gum and lignin to be commercially useful. Bleaching with gaseous sulfur dioxide has been advocated but the resulting fiber turns a decided yellow if given the bleaching treatment such as is customarily given wool. Accordingly such fibers are undesirable as, when mixed with wool and made into cloth, the resulting cloth cannot when being washed and finished be given a' bleach treatment as is often done with wool cloth.
An object of the invention is to provide a process which overcomes the shortcomings of rocedures heretofore proposed.
nother object of the invention is to provide a process capable of modifying or changing the characteristics of certain vegetable fibers so that they may be suitable for use in the textile arts. 7
A further object is the provision of a proceduce which makes it possible to convert vegetable fibers of commerce ordinarily em- Application filed September 26, 1929. Serial No. 395,457.
ployed for rope makingor the like into texall Search Room tile fibers capable of being carded, spun and woven or knitted in a commercial manner.
.A further object is the provision of a procedure by which certain vegetable fibers may be given the crinkle, the soft feel and handle and other characteristics of wool so that they may be used in the textile industry either in place of wool or in admixture with wool.
It is also within the contemplation of the invention to provide a process which can be carried out on an industrial scale on a simple, economical and practical basis.
Our invention is based upon the discovery that vegetable fibers will yield to a treatment with a group of reagents and a series of operations so correlated and coordinated with each other that no hardening or embrittling or contamination with the particles of the reagents occurs and that a soft, crinkled fiber having relatively great strength, being susceptible to dyeing with practically all of the usual dyes ordinarily employed with Wool, and being capable of handling with the machinery and equipment now installed and used in the wool industry is produced.
By the present process a wool-like prodnot can be made from a number of vegetable fibers. One of the best of these fibers f0 our process is jute.
As is well known, jute is grown in India and elsewhere and is normally packed in bales weighing about 400 pounds.
The bale is first opened up and the jute cut into pieces four to seven inches in length. Eight hundred pounds of jute are put into a tank containing 1000 gallons of water which has about forty-five pounds of tri-sodium phosphate dissolved in it. The solution is kept approximately at the boiling temperature for about two hours. In this operation much coloring matter is removed and there is some swelling and loosening from each other of the fibers. This treatment is repeated sev- 8. tttacmmu a uvuwu; rLum cm N 0F TEXHLES & FIBERS, ll.
eral times. In practice the solutions which have been used in earlier runs are reused in such a way that'the'jute is first treated with the oldest and hense dirtiest solution and finally with a fresh solution of tri-sodium phosphate. v
The thus-treated jute is then removed from this solution and the phosphate is roughly washed therefrom, that is, the treated jute is washed until it no longer feels soapy to the touch.
The next step is to heat the fiber in anapproximately 4% solution of sodium bisu'lfite for an hour or two at the boiling temperature. This treatment rapidly opens up the fiber, removesthe gummy materials adherent to the fiber, and changes the color from red to a light yellow. The fiber is then removed,
washed thoroughly with water, and partially dried or pressed to remove the major portion of the adhering water.
The. following step is for the purpose of producing the crinkle in the fiber and consists of immersing the dried fiber in a caustic soda solution of about 18% strength. If the fiber is damp the bath of caustic soda will have to be of additional strength to, compensate for the water adhering to the fiber. The bath is kept at approximately room temperature and the immersion continued until thorough contact between the fiber and solution occurs. This will ordinarily require about.
two hours. The fiber is then removed from the caustic soda solution, theexcess ofsolution pressed out as far as possible, and then thoroughly washed with plenty of water. The fiber at this stage is dark in color and carries gummy material produced by the action of the strong caustic soda solution on the ligninof the fiber. The fiber is boiled for one hour in a 4 to 5% sodium bisulfite solution to remove this gummy material after which it is washed again.
To bleach the fiber it is soaked in a. very dilutemineral acid solution, e. g. one part of strong commercial hydrochloric acid (or sulfuric acid) diluted with 200 times its volume of water. This stee ing in acid at room temperature has the e ect of removing much of. the color. The fiber, which is now cream color, is next well washed with water and dried. This color of the fiber is such as to permit its being sold for most industrial uses without further bleaching.
However, if additional bleaching is desired, it can be accomplished with simultaneous increase in the softness of thefiber. For bleaching we prefer a solution containing about 1% of potassium permanganate calculated on the dry weight of the fiber to be treated. This is used in a solution of about 1 part of permanganate in 2000 parts of water. The bleaching is continued at room temperature for about two hours. Any trace of excess of permanganate or precipi- Search tated manganese dioxide is removed by one of the agents customarily used for such pur' pose. The fiber is then washed, pressed out,
immersion in a warm glycerine and soap solution made by dissolving one half pound each of glycerine and neutral soap in 100 pounds of water. '7
While we have described a specific embodiment of our invention by way of illustration, it is to be understood that we are not to be confined to the exact steps, reagents, proportions or particular devices mentioned hereinabove as they are to be regarded only as illustrative and typical, for example, caustic soda may be used as an equivalent of tri-sodium phosphate and the bleaching agents customiarily used for wool may be used in place of potassium permanganate- Various embodiments of our invention may obviously be readily made by those skilled in the art without departing from the spirit and scope of our invention as defined in the appended claims.
