In- France November 8, 1929 2 Claims.
This invention relates to improvements. in spinning processes and also relates to products obtained by the said improved processes.
It has been proposedheretofore to unitethe 5 several fibres composing a thread by impregnating the latter, after spinning, with various.
finishing substances or with a rubber solution. It has been found, however, that these substances do not penetrate sufiicientlyinto the thread and do not reach its core or surround each fibre.
According to this invention, the impregnation takes place during the operation of spinning, that is to say between the moment when the textile is in the form of roving and that when it is w drawn out into thread. In this manner the penetration of the liquid is complete, since every fibre is made wet by the same. Among the impregnating materials which may be used in the present process, may becited suspension or 0 dispersion in water of natural or synthetic rubber, gutta or balata (natural or artificial latex) or plastic materials such as gelatine cellulose ethers; fatty and cellulose ethers.
The thread obtained after spinning and dry- 5 ing is constituted by cellulose fibres and elastic or plastic substances united together-at the center of the thread as wellas at its periphery. The impregnating substance forms between the fibres and elastic bond having high mechani- 5 cal properties, enabling them to give less torsion to the thread for the same resistance to be obtained; furthermore the quality of the fibres used may be of an inferior order.
According to the nature of the impregnating material utilized, the impregnated thread may be submitted to subsequent operations; for instance to that of elimination of the liquidin which the, elastic or plastic material has been dispersed, or to that of vulcanization when it is 4 a question of vulcanizable impregnating materials, or to that of polishing or other finishing. The thread may also be twisted or stranded from several threads, with additional impregnation .from the suspension or solution liquid and driedwhilst retainingtheir elastic or plastic properties, more particularly as regards the adhesion and the binding of the fibres togethenand adapted to give to the threads a polished surface by' agglomerating the fluff.
The present process may be applied on the self acting spinning frames or on ring frames,. the fibres in both 'cases being impregnated with v elastic or plastic material before the drawing and the twisting. The impregnation is preferably effected bypassing the roving through a suspension, dispersion or solution of elastic or plastic n ateriaha cleaning liquid being moreover'utilized desired before the drawing.
The accompanying drawing shows diagrammatically by way of example:
In Figure 1 theapplication of the present process to a ring spinning frame. it In Figure 2 the application of the said proc-- ess to a mule spinning frame.
In the'construction of Figure l, the rovin'g'l coming from the bobbin 2 passes under ,a pulley 3 carried by a support 4 pivoted at 5, which forces it to pass through a baths of impregnating material provided in a vat 7. In the bath 6 which is constituted by elastic or plastic material in dis 'persion, either in suspension ,or in solution in a liquid, the roving is impregnated with the elastic '8 or plastic material which penetrates thoroughly into the interior of the roving, between the fibres which constitute it, the said penetration being facilitated by the fact that the fibres which constitute the roving, possess in that state a great freedom relatively to each other. On leaving the bath 6,- the roving 1 after having passed for instance over the edge Bo'f the vat so as to retain and send back into the bath the excess of the impregnating liquid, passes between the pairs of 0 rollers 9-911, 10-10a, 1l-11a of the ring spinning frame, which'bring about the drawing out of the roving The rollers 9a, 10a, 11a. are of metal, and the rollers 9, 10, 11 are surfaced with.
rubber. In passing between the said rollers, the
roving is drawn out in the ordinary way. During the said drawing, the fibres slide or slip relatively to one another in order to assume'their permanent relative positions, whilst remaining impregnated and coated with the elastic or plastic $1 material so that, on leaving the last pair, the fibres have assumed their definitive longitudinal position relatively to one another, whilst being arranged side by side with the interposition of a slight layer of elastic or plastic material. During .1. their passage between the pairs of rollers, a certafin quantity of elastic or plastic material is expelled owing to the compression exerted by the rollers on the impregnated roving. This excess ofelastic or plastic material is removed from the 1110 rollers 9a, 10a, 11:; by scrapers 92), 10b, 11b and drops into a vat 12. On leaving the drawing rollers 11-11a the roving is subjected in the usual manner to twisting by means of a spinning bobbin 14 provided with its ring traveller 15 and rotated by means of the rope 16.
i A pipe 1'7 provided with branches 18, 19, 20 makes it possible to direct towards the drawing rollers 9, 10, 11 and towards the roving 1 during its drawing out, any suitable liquids which can act on the roving for the desired purpose, for instance a cleaning liquid such assoapsuds intended to clean the roving and to facilitate the drawing out and the twisting of theroving impregnated with elastic or plastic material. The excess of soapsuds flows on the rollers 9a, 10a, 11a and is removed by the scrapers 91), 10b, 11b and then drops into the draining vat 12'.
The bath 6 of impregnating liquid, through which passes the roving, may consist of any suitable elastic or plastic material dissolved, dispersed or emulsified, for. instance a solution of cellulose ether in one of its solvents, an aqueous dispersion of cellulose ether, for instance of viscose, natural or synthetic rubber solution in one of its volatile solvents, an aqueous dispersion of rubber (latex) or any other equivalent elastic or plastic materials adapted to impregnate the fibres of the roving and to bind them together.
In the apparatus shown in Figure 2, which corresponds to the spinning with a mule, the roving .1 is shown unwinding from a bobbin 2 which is here horizontal, the pulley 3 with support 4 pivoted at 5 and the bath 6 contained the vat "I being similar to the correspondingly numbered parts of Fig. 1. The roving 1 then passes between a pair of rollers 9-9a provided with a scraper 9b, with a draining vat 12 and a pipe 18 for the admission of the cleaning liquid, for instance soapsuds. At 21 is shown the carriage of the mulecarrying the spinning bobbin 15 oper- 'phurous anhydride, or hot.
ated by the rope 16, and the rotating tube 22 carried by the taller 23. The impregnation of the roving of the thread with elastic or plastic material takes place in the said construction in the same manner as described in connection with Figure 1.
. The bobbins of thread obtained with the ring spinning frame or with the mule are preferably unwound for completing the drying of the thread.
In the case of impregnation with rubber to which vulcanizable materials are added, the vulcanization may be proceeded with, if desired, by
the usual methods, either cold, that is to say by the action of sulphur monochloride or by the successive action of sulphuretted hydrogen and sul- In the latter case with the solution of rubber or with the latex is previously incorporated sulphur or polysulphide and the usual necessary accelerating agents.
