TREATMENT OF FIBROUS TEXTILE MATERIALS The invention relates to an apparatus for treating a mass of random animal raw textile fibers, mainly wool fibers, for the purpose of ensuring its soaking, cleaning, rinsing, and drying if need be.

A treating apparatus according to the invention comprises a vat which contains a treating liquid and a plurality of transfer members such as rotating cylinders or endless belts provided with holding elements such as points, hooks or roughened regions, arranged in such a manner that the holding elements of the various transfer members penetrate into each other in contact zones in'the vat which are immersed within the liquid, the orientations of the said holding elements, the directions of movement of the transfer members and their respective linear speeds being such that the mass of fibers conveyed to the first transfer member is taken up successively by the others and each time is subjected to a certain drawing action.

The invention will next be described with reference to the accompanying drawing, the sole figure of which diagrammatically shows, in a non restrictive sense, an elevation view of one embodiment of an apparatus for treating a mass of animal textile fibers in accordance with the invention.

The apparatus for the treatment of a sheet of mass of random animal raw textile fibers, mainly wool fibers comprises a vat 1 containing a bath of treatment liquid 2, in which are mounted a certain number (five in the example) of transfer members constituted of rotating

cylinders

51, 52, 53, 54, 55 provided with

points

61, 62, 63, 64 and 65 respectively. The said cylinders are arranged in such a way that the points of each of them penetrate into the gaps between the points of the following cylinder. Moreover, each cylinder rotates in a direction opposite'the direction of rotation of the preceding cylinder, at a peripheral speed which is slightly higher than the peripheral speed of the preceding cylinder. On each cylinder the points are inclined forwards, in the direction of their movement, so as to be able to hook well into the material; moreover, they are shorter than those of the preceding cylinder and there are more of them.

The transfer cylinders are mounted in the vat l in such a way that their zone of contact is immersed in the bath of liquid 2. It is accordingly quite in order to arrange the first cylinder 51 above the second cylinder 52 and the last cylinder 55 above the next to last cylinder 54; the intermediate cylinder 53 can be located either at the same level as the two other lower cylinders 52 and 54, or at different levels, if desired. Moreover, instead of a single intermediate cylinder 53 a greater number can be employed, provided the said number is odd.

The mass of fibers 17 to be treated is conveyed to the first rotating cylinder 51 by any suitable feed means, such as for instance an endless belt 18 of any suitable type.

In the arrangement shown, the end downstream of the endless belt 18, which is located in the immediate vicinity of the entry cylinder 51, is surmounted by another holding cylinder 19 provided with points 21 which are rearwardly inclined, in such a way that the material engaged by the first cylinder 51 is already subjected to a first drawing effect by reason of the fact that it is to a certain extent held between the cylinder 19 and the belt 18.

The relative speeds of the various cylinders are such that in passing from one cylinder to the next the mass of fibers is subjected to a drawing at a rate of, for instance approximately 1.2 to 1.5.

An endless detaching belt 67 is arranged on the discharge cylinder 55, said belt passing also over a drum 68 in such a way that the upper strand of the said belt is preferably substantially horizontal.

The end downstream of the endless belt 67 overhangs an endless removal belt 58 which guides the treated material between two calendering

cylinders

28, 29, from where it is taken by another endless belt 32.

The operation of the device is as follows: the mass of fibers l7, conveyed b the belt 18 to the first cylinder 51, is subjected to a first rawing between the

cylinders

19 and 51, then it passes successively over the

other cylinders

52, 53, 54, 55 with the result that it is progressively drafted, opened, homogenized and the fibers are orientated parallel to each other, while at the same time it is immersed under very good conditions in the treatment liquid 1. The thus treated sheet is detached from the first cylinder 55 by thebelt 67 and it falls onto the belt 58, passes between the calendering

cylinders

28, 29 and is finally removed on the last belt 32.

lt should be understood that the invention is not restricted to the embodiment described and illustrated, and that modifications can be made therein without thereby going beyond the scope of the invention.

1 claim:

1. An apparatus for treating a mass of random animal raw textile fibers said apparatus comprising a vat which contains a treating liquid and a plurality of successive rotatable cylinders including fibre holding elements thereon immersed in the liquid and arranged such that the holding elements of the cylinders interpenetrate each other in contact zones in the vat within the liquid, and means for rotating each cylinder in a direction opposite to that of the preceding one and at a slightly higher speed, the holding elements of all the cylinders projecting therefrom and being inclined forwardly with respect to their direction of movement, such that the mass of fibers conveyed to the first cylinder is successively taken up by the others and each time is subjected to a drawing action.

2. An apparatus as claimed in claim 1 wherein the length of the holding elements of each cylinder is less than that of the holding elements of the preceding cylinder.

3. An apparatus as claimed in claim 1 wherein the number of holding elements of each cylinder is at least equal to that of the holding elements of the preceding cylinder.

4. An apparatus as claimed in claim 1 wherein the first rotatable cylinder is disposed vertically above the second cylinder and the last cylinder is disposed vertically above the next to last cylinder, the cylinders between the first and last being horizontally disposed in the vat and immersed in the treating liquid, the fiber mass traveling in serpentine fashion over one cylinder and below the next.
