Description

Patented Dec. 19, 1950 UNITED STATES PATENT orrlcs;
MODIFICATION OF B. A.-TYPE WOOL Stuart E. Swanson, Sufiield, Conn, assignor to Bigelow-Sanford Carpet 00., llnc., Thompsonville, Conn, a corporation of. Massachusetts No Drawing. Application February'10,'1949, Serial No. 75,739
3 Claims.
. ture of pile floor coverings.
Hitherto it ha not been. possible, because of their. soft slippery nature and their tendency to create static, to process these B. A.-type wools by conventional carpet manufacturing'machines and procedures as thepile. of rugs and carpets or to mix desired quantities of such wool with the harsher and coarser wools in such manufacture.
I have discovered; that by treating these soft, silk-like, lustrous, slippery B. A.-type Wools with a dilute aqueoussolutionof a zirconyl compound, preferably in a bath containing the zirconyl compound, the fibers of these wools are rendered harsher, coarser and fuller or bushier so that they may be handled by the methods conventional in the carpet manufacturing industry; in which methods the coarser and hardier conventional carpet wools are used. Also, at the same time, the lustre of said fibers, which is undersirable in conventional domestic rugs and carpets, is decreased.
An example of my treatment is as follows: A batch of raw B. A. wool stock weighing about 900 pounds is immersed in a dilute aqueous solution of 18 pounds of sodium zirconyl sulfate dissolved in about 4,000 gallons of water. The bath is brought to the boil and the W001 exposed to the action or" the hot sodium zirconyl sulfate solution, during which operation the wool Will absorb substantially the entire zirconyl compound content of the bath. If desired, the liquid may be brought to the boil before the sodium zirconyl sulfate is added.
Conveniently, the wool may be subjected to the treatment of this invention concurrently with the dyeing of the wool. The following example illustrates treatment of the wool in this way:
The wool, preferably in raw stock form, is immersed in the dye-bath and subjected to the normal dyeing operation, in which the bath is brought to the boil and the wool exposed to the action of the hot dye liquor. As the dyeing operation nears completion, that is when only about fifteen minutes more are required to complete the dyeing, a concentrated solution of sodium zirconyl sulfate is added to the bath in an amount andconcentration such as to provide in. the bath about 2% of sodium. zirconyl-sulfate. basedeon the weight of the wool. The dyeing operation is continued, with boiling of the bath, for about fifteen minutes,during which time. the woolwill absorb-substantially the entire zirconyl compound content of the bath. If desired, the sodiumzirconyl. sulfate, may be added to the bath before the wool is entered, or before the bath is brought to the boil. The zirconyl compounds used, in the. present invention. are compatible with all types of dyes.
The duration of the boiling treatment. in. the presence of the zirconyl compound may extend from approximately 10 minutes toabout an .hour.
The amount of the zirconylcompoundpresent in the treating bath may be varied, depending upon the temperature and the duration. of the treatment and. upon the extent of the modification desired: in the wool, butthe bath. should be sufficiently dilute to cause substantial ionization and hydrolysis of. the zirconyl compound, When the treatment is carried out as a batch operation, as in: the batch process described, amounts of zirconyl. compound ranging. from 4 to. 10%, of the weight of the wool, preferably about 2%, have been found to give good results.
The modification of raw wool stock or the yarn also may be effected by use of a cold solution, containing the zirconyl compound, by allowing the wool to remain standing therein for a sumcient period of time. In such case the bath may be substantially exhausted of zirconyl compound and the zirconyl compound may be present in an amount ranging from /8 to 10% of the weight of the wool, preferably about 2%. When the zirconyl content of the bath is about /8% to 10%, based on the wool, exhaustion may .be obtained at room temperature in about 48 hours. The same results can be obtained in shorter time by increasing the temperature or the concentration of the bath, preferably the temperature.
When the wool is treated with the zirconyl compound by the foregoing procedures, the zirconyl compound is completely or substantially completely exhausted from the treating bath and the amount of the compound absorbed by the wool is controlled by the amount of compound in the bath.
Another mode of treatment is to treat the wool with the zirconyl compound as a continuous operation in a moving stream of treating liquid. Thus the wool may be treatee as it i subjected to the rinsing operation which normally follows the scouring operation in the preparation of wool fibers for use in pile fabric floor coverings. This procedure is particularly useful with wools which are not to be dyed but are to be manufactured into yarn of their natural color. In many cases the rinsing following the scouring operation is carried out with water at a temperature of about 140-l60 F., although rinsing at any temperature between room temperature and the boiling point may be employed. The zirconyl compound content of the rinse bath I should approximate to 10%, preferably about 2%, of the weight of the Wool. The wool is passed through the rinsing tank in a continuous operation and the zirconyl compound therefore must be continually supplied to the tank to maintain the desired concentration of the compound therein. For this purpose any appropriate, constantrate feeding means may be employed.
Other zirconyl compounds which I have found to be effective in modifying the wool in the same way as sodium zirconyl sulfate are zirconyl sulfate, zirconyl formate, zirconyl acetate, and ammonium zirconyl carbonate.
The wool so treated may be spun into yarn, which, as well as yarn so treated, may be then woven as the pile of pile floor coverings. Such pile has a coarse, harsh texture and a lack of lustre very difierent from the texture and lustre of the untreated wool. The pile of the carpets made with my treated wool has the harshness,
coarseness, lack of lustre and plumpness of the coarser wools conventionally used as the pile of pile floor coverings.
My treatment may be applied to the skeined wool yarn before, during, or after dyeing as well as to the raw stock.
Wool treated by my process may be mixed with conventional carpet wools in all proportions to give a wool mixture suitable for use in forming I the pile of pile-fabric floor coverings.
By the term B. A.-type wool as used herein, I mean wool having the characteristics of B. A.
f wool as regards its soft, slippery nature, its
luster and its lack of harshness and fullness as contrasted with the conventional carpet wools.
I use the term B. A. wool in its ordinary meaning in the trade, 1. e., wool from the Lincoln-type sheep as grown in South America. The B. A. type wools available today consist primarily of B. A. wool and wool from the Lincoln sheep as grown in New Zealand.
This application i a continuation-in-part of m application Serial No. 780,111, filed October 15, 1947, now abandoned.
I claim:
1. The process for enhancing the harshness and fullness and decreasing the luster of B. A.- type wool which comprises treating the wool with a liquid consisting essentially of a dilute aqueous solution of a zirconyl compound in an amount between and 10% by weight of the wool.
The process as in claim 1 in which the Wool is immersed in a bath of the treating liquid for from 10 to 60 minutes at the boil.
3. The process as in claim 2 in which lower than boiling temperatures and longer periods of time are used.
