Description
Patented Apr. 7 6, 1937 UNITED STATES PATENT OFFICE METHOD OF FINISHING KNIT FABRICS Camille Dreyfus, New York, N. Y.
No Drawing. Application December 8, 1932, Serial No. 64,6305
This invention relates to. the finishing of knit fabrics containing yarns of organic derivatives of cellulose and relates more particularly to the: finishing of knit hosiery containing such yarns knit hosiery or stockings containing yarns of organic derivatives of cellulose under such condim tions' that the stockings do not become wrinkled,
creased or distorted. Other objects of the invention will appear from the following detailed description. I
As is well known, after theknitting operation in the manufacture of stockings, the stockings are subjected to a finishing treatment which may comprise, broadly, delustering, dyeing and drying the stockings, In the methods of finishing hosiery, as heretofore commonly practiced, it was exceedingly difiicult if not impossible to finish stockings containing yarns of organic derivatives of cellulose without leaving wrinkles and creases in the fabric.
One of the usual methods of effecting the final operation of drying and forming-stockings is to board-the stockings afterthe dyeing step, from which the stockings come ina substantially dry state, and then pass the boarded stockings through-the drying chamber of the boarding machine where a temperature of 220 F. is maintained. However, when stockings containing yarns of organic derivatives of cellulose are sub-'- this treatment, there is grave danger of producing anunsaleable product full of wrinkles and creases. I have made the surprising discovery that by subjecting stockings containing yarns of organic derivatives of cellulose to higher temperatures while they are in a wet j condition, or by subjecting such stockings in the presence of oils to lower temperatures, satisfactory products free from wrinkles and creases may be produced. 7 1
' In accordance with one'form of my invention, I prepare stockings containing yarns of organic derivatives of cellulose free from wrinkles and. creases by boarding the stockings, after they have beenjdyed, on a suitable hosiery dryer. I then wet the stockings on the boards in any suitable manner and pass them through the drying cham' ber of the hosiery dryer in which chamber a temperature exceeding about 220? F., preferably about 260 F. is maintained. If the stockings are placed on forms that are heated internally, lower temperatures, say 160 to 200 F. may be employed. Thestockings are then removedfrom by spraying or sponging,
the boards free from wrinkles and creases. In another form of my invention, the stockings are subjected to heat on suitable forms, while having an oil applied thereto.
Stockings made from yarns of any suitable or- 5 ganic derivatives of cellulose such as organic esters of cellulose and cellulose ethers, maybe treated in accordance with the foregoing method in. order to produce a productfree from wrinkles and creases. Examples of organic esters' of cellulose are cellulose acetate, cellulose formate, cellulose propionate and cellulose butyrate while examples of cellulose ethers are methyl cellulose, ethyl cellulose and benzyl, cellulose. Stockings which do not consist wholly of yarns of the organic derivatives of cellulose but also contain yarns-of other fibres, such as silk, cotton, wool, reconstituted cellulose, etc.'may also be freed of wrinkles and creases "by subjecting the stockings to the above outlined treatment. v 20 Referring more particularly to onemethod of carrying out my invention, stockings containing yarns of organic derivatives of cellulose, which. stockings come from the dyeing operation in a substantially dry condition, are boarded, that is, 25
each stocking is drawn onto an individual board on a hosiery drying machine, the board being somewhat flattened in cross-section and shaped to conform to the shape of the stocking. The boards are made of any suitable rush-resisting metal. After the stockings are boarded, they are wetted with water in any suitable manner as and are then passed through the drying chamber 01' the hosiery dryer. The temperature of the drying chamber is main- 35 tai'ned at 260 F.
In another form of carrying out my invention, the dyed stockings containing yarns of organic derivatives of cellulose are boarded and instead of being wett'ed with water are sprayed or sponged 40 with an aqueous emulsion of oils, containing from 10 to c. c., and preferably from 50 to 100 c. c.,- per litre of olive oil, or other oil such as castor oil, cottonseed oil, Turkey red oil, mineral oils,
or other oils, or mixtures of two or more of such 5 vidually heated, such as by steam passing through 55 lose from wrinkles and creases comprises boarding the stockings in a substantially dry condition on steam boards or boards heated by any other suitable means, sponging or spraying the stockings with water and permitting the same to dry on the boards'which are heated internally by steam or other heating fluid. The stockings with the wrinkles and creases completely removed are then stripped from the boards. While good results are obtained when such boards are heated to 120 to 180 F., the best results are obtained when the boards are maintained at a temperature of from 160 to 180 F.
It is to be understood that the foregoing detailed description is given merely by way of illustration iand that many variations may be made therein without departing from the spiritof my invention. 1
