PROCESS FOR RAISING AND cunpme ms FLUFFS 0F FA Filed Aug. 28, 1937 M242 wring Patented May 6, 1941 PROCESS FOR narsmc AND OURLING 'rnE rnnrrs or names Bruno Sonnino, Milan, Italy Application August as, 1937, Serial No. 161,432 In Italy September 11, 1936 6 Claims.

It is known that raised or more or less fluii'y cloths, present on their finished surfaces a layer of fluff or a nap, which is meant to render'the cloth soft and to enhance its warming properties.

The object of the present invention is a process for the raising and curling of the hair or fiuif of raised cloths, or of cloths that are anyhow flufiy, in order to attain a very high layer of 'flufi (about twice or three times what is normally produced) and accordingly an air cushion, while the cloth will present great softness, and, as a consequence, greater insulating properties, which is apt to impart to the cloth a greater smoothness, while the air cushion causes the warming properties to be increased.

The said process essentially consists in submitting the fiufl' of the cloth to be treated to the action of a strong jet of air, either mixed with liquids or otherwise conditioned, or oven pure, such jet or pets of air being directed upon the fluff either perpendicularly or obliquely.

The annexed drawing schematically shows by way of example one of the most elementary methods to actuate the process according to the invention; in the said drawing:

Fig. 1 shows a piece of cloth undergoing the action of a fluid jet, seen from a side.

Fig. 2 shows the same seen from above.

Fig. 3 shows amulti-nozzled jet. i

Fig. 4 shows a system for the treatment the cloth onboth sides.

With reference to the anexed drawing: I shows a supporting surface for the cloth, made ofa light close metallic net stretched on a fixed frame;

- 2 shows the cloth under treatment: 3 is the nozzle that communicates with two flexible or stiff pipes or tubings, l and 5, the one for the liquid and the other for the compressedair supplied from acompressor. The said nozzle may be fitted upon a reciprocable carrier or other shifting device, if desired, although not shown in the drawing.

The same result will be attained .if in any' a series of jets 6, on a beam or transversal sup port fitted above the cloth, while the cloth is.

caused to run slowly under the said series of and the nozzle support'be shifted moving the mixed with other suitable fluids or not-may be jets. Otherwise, the cloth may not move at all,

nozzles in the direction of the flufi or vice-versa.

The said nozzle support may even be imparted a longitudinal vibratory movement.

In all the above said instances, the jet or jets of air, whether this be conditioned or not, thrown upon the flufl' 2' of the cloth (which fiufl? will be lying flat in one direction) will cause the fluff to rise owing to the whirlwind effect of the air ruilling it and causing it to remain standing or curled or so twisted together as to form a layer offering a very soft air cushion 2" (Figs. 1

and 2).

The operation, instead of its being carried out first on the-,one side or face of the cloth, and then on the other, may be carried out simultaneously on both sides, by treating the cloth on both sides at the same time.

' Instead of air, steam--whether mixed with other suitable fluids or not or gases of any kind used. a

The metallic net may be substituted by any kind of fabric, whether stretched or by smooth surfaces, of either wood," or iron or any other such likematerial.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

, l. A process for raising the nap 0r fiuil' of raised cloths or cloths otherwise fiuffy, in which the fiufi' is flat and lies in one direction, which consists in subjecting the surface of said cloth upon one side to the action of at least one jet of fluid which is directed against said side and at an angle with respect to the. plane of the cloth, causing the jet of fluidto pass with an alternate movement over said surface in a direction transverse to the direction in which the fluff lies in order to produce a-whirlwind effect among the flufi fibres which will thus be raised,"curled and interwoven, with a resulting increase of the thickness and softness of the layer of fluff treated, and combining said alternate movement with a longitudinal intermittent movement at the end .of each stroke of said alternate movement,

in order to treat, step by step, the entire surface 3. A process according to claim 1,'wherein the fabric is moved longitudinally intermittently of fluid are directed simultaneously against-both while the jet is moved transversely of said, longisides of ,the cloth.

tudinal movement. 6. A process according to claim 1, wherein the 4. Aprocess according to claim 1, wherein a length is varied o! the transverse movement of plurality of stationary jets are arranged across 5 the jet-with respect to the direction in which the the entire width of the cloth while the latter nap oi the cloth lies.
