11 Claims.

This invention relates to a new textile intermediate product and to a. process for the manufacture thereof.

In order to subject threads and yarns to treatment and further working-up,v they are worked up into particular intermediate products or brought into intermediate forms, for example wound into spools and brought into the form of skein or hank; very often in the working up and treatment, for example bleaching, dyeing, dressing of the threads and yarns, and also in the course of the manufacture of finished: products, such as fabrics of the threads or yarns, multiple re-spooling or re-conversion into the form of hanks or skeins is necessary.

An object of this invention is to provide a new textile intermediate product comprising a cable of threads or yarns which may be stored, handled or mechanically, physically or chemically treated and which may be brokenup at a desired moment into individual threads or bundles of threads.

Another object of this invention is to provide a subdivisible thread cable consisting of several hundred to several thousand of parallel individual threads or yarns of some hundred metres to some thousand metres. I

Another object of this invention is to provide a process for providing a textile intermediate product resulting in a subdivisible thread cable, allowing a subdivision of said cable into the original thread bundles.

Other objects of this invention will appear as the description proceeds.

The textile intermediate product of the present invention constitutes an independent product and consists of a cable formed of a very large number, for example of from several hundred to several thousand of parallel individual threads or yarns adhering to one another, while the cable is subdivided into individual threads at least at one end, and on occasion at both ends, by at least one thread or strip passing through the cable in windings transversely to the, longitudinal direction of the cable.

The term individual threads used herein is intended to include bundles of individual threads,

, such as are produced for example in the production of artificial spinning fibres as a union of the threads coming from a nozzle, and also yarns.

According to a preferred form of production of the intermediate product of the invention, two cross-threads or cross strips are disposed at the end of the cable, at a distance from one anotherin: the longitudinal direction of the cable,

and pass through the cable in different windeven of several kilometres, and in this form, for

example when taken offin zig-zag form or wound on to drums or the like, may be stored and also handled, as well as treated mechanically, physically, or chemically; they may at any desired moment be broken up into individual threads (or bundles of intermediate threads) by the crossthreads or cross-strip passing through the end of the cable.

Textile intermediate products according to the invention, namely independent, subdivisible thread cables can be produced by first guiding individual threads (or thread bundles) in the same-direction at distances from one another and connecting them in this mainly flatly spread out condition with at least one thread or strip running transversely to the direction in which they run, and then guiding together the individual threads, together with the cross-thread or cross-threads or cross-strip or cross-strips, to form a thread cable and by the temporary application ofa lateral pressure by a thread guider causing them to adhere mutually in the thread cable. A particularly convenient method, particularly" for producing cables capable of being broken up and having two-cross-threads or crossstrips provided at the cable'end, consists in forminga shed of the individual threads and bundles respectively guided at distances from one another, aiter'the style of warp threads, twice with a change of the shed, and inserting one crossthread or cross-strip through each doubling after the style of a weft thread, whereupon the threads are guided together and united to form the thread cable.

A particular advantage of the hereindescribed method resides-in the fact that it can be carried out in a continuous working operation. The subdivisible thread cable of the invention can be; thus produced directly following the process of production of the individual threads, for example the spinning process. The textile intermediate product of the invention, or the process employed for its production, thus gains particular importance for artificial spun threads, such as rayon, polymeride or polyamide threads, or the like.

In the production of rayon the coagulated thread bundles drawn off from the spinning jets having apertures numbering about 12 to 100, after stretching, were hitherto either wound on to spools or twisted in spinning centrifuges into the form of so-called cakes, and thereupon subjected to various after-treatments in the form of spools or cakes. In the production of artificial spun threads, in which the spinning is carried out with nozzles having high aperture numbers of about 1000 to 5000 apertures and more, the bundlesof coagulated threads formed at the nozzles (known for the sake of brevity as spinning slivers) are united in some manufacturing processes to form a thick thread bundle of several thousand to over one million deniers and in this form are jointly stretched and then cut up into staple fibres. Such a thread bundle does not, however, form an independent intermediate product which can be handled by itself.

In contradistinction thereto, in the production of an independent intermediate product according to the present invention in the form desired number of approximately equal parts,

and these parts are united with the cross-thread or strip or cross-threads or strips, whereupon they are guided together to form the threaded cable.

The cross-threads or strips should have a rather greater length than the distance between the two outermost individual threads or bundles at the point of insertion or application of the cross-thread or cross-strip. When closing up the individual threads or bundles of individual threads to form the cable, the cross-threads or strips will come to lie in irregular windings between the individual threads, so that the cable can be separated again into the individual threads or individual bundles at the ends through which. the cross-threads pass.

The thread cable may consist of thread bundles of continuous artificial spun fibres, for example rayon threads. It may, however, also consists of bundles of twisted artificial fibres, or else of threads and yarns of natural fibres, for example of cotton yarns. The novel textile intermediate forms of the thread cable of the invention can advantageously be employed where a multiplicity of continuous threads (whereby yarns are also to be understood) are to be improved mechanically, physically, or chemically, for example by stretching, drying with the aid of air, steam, or gases, by Washing, bleaching, dyeing, mercerising, parchmentising, and the like. The divisible thread cable of the invention can be subjected to all these and similar treatments, and then be broken up into individual threads or individual thread bundles, after which the individual threads or thread bundles can be further worked up, for example twisted, woven, or otherwise converted into finished products. For example, in the rayon industry the individual thread bundles (about 60 threads of a thickness of 2 deniers each thread) may be subdivided in the manner indicated with the aid of the cross-threads or strips, united to form the cable, and the latter may be washed, desulphurised, revived, and for example be taken off, out up into lengths or several hundred or thousand metres. By dividing the cable taken off by means of the cross-threads or strips, the individual thread bundles can then be separated from one another and subjected separately to further treatment, for example to twisting.

A thread cable which consists of threads or thread bundles which are in a damp condition may also be taken off without drying and further be treated after storage and transport in the damp condition, so that intermediate drying is saved. The loose individual threads or bundles may also be subjected to the most diverse treatments before being united to form the cable and the thread bundles may be united to form the thread cable only after the different treatments or at any rate after drying. 1

It is thus visible that the formation and treatment of the thread cable are possible in the most diverse modifications. In order to assist the individual threads or bundles to adhere to one another to form the closed cable they may be grouped together either in the natural damp condition or after artificial damping to form the cable. The threads may, however, be provided with a medium which promotes adhesion, for example with a light coating, before the cable is formed. When treating threads of a viscose, for example, the thread bundles or the already closed cable may be treated with a washing solution, which is produced by diluting a normal spinning viscose with water at a temperature of 40 C. in the proportion of 1:10 to 1:20, whereby slight mutual adhesion of the threads is obtained.

In weaving, particularly in the production of patterned or multicolour fabrics, it is known to effect the sequence of the threads or thread groups of a thread layer by crossing them by means of so-called cross bars or cross cords. In this known method of operation the individual threads or thread groups forming a spread-out thread layer at the warp beam are kept apart by the cross bars or cross cords. In contradistinction to the present invention, the known method of operation produces no union of individual threads or thread bundles to form a closed thread cable.

The invention will hereinafter be more fully described with reference to the accompanying drawings, which illustrate various embodiments of the textile intermediate product of the invention and of apparatus for producingthe same.

The intermediate product illustrated in Figs. l'to 3 consists of a cable A, which consists of a very large number of individual thread bundles 40. For the sake of clarity only a far smaller number of individual. thread bundles have been assumed in the illustration of this. product, and these have been serially numbered I, 2, 3., 33, 34, 35. The individual thread, bundles 4B,.

which in turn consistof a large number of individual threads, for example 3|) to 50, run parallel to one another and adhere to one another (Fig. 2). At at least one end of the cableA, this end being illustrated in Fig. 1, the cable has two cross-threads 41, 42 passing through it, which run in windings through the cross-section of the cable at a distance a from one another. For the better representation of this arrangement the cross section in Fig. 3 is shown loosened. The ends 41., 4!" and. 42", 42." respectively project slightly from the cable A, so that they can easily be grasped for the purpose of separating the cable into the individual thread bundles. As can be seen from Fig. 3, the paths of the windings of the cross-threads 4!, 42 through the cable are different, but in such a manner that the windings of the cross-threads when the latter are pushed together to the extent of the distance a, supplement one another to form closed loops, and each individual thread bundle 40 is completely embraced by such a loop. The length L of the cable may in theory be of any desired magnitude; in practice great lengths in particular have been found advantageous, conveniently lengths lying between 500 metres and several kilometers, for example up to 10 kilometers. Even in cables of these great lengths there is no special joining of the individual threads; on the contrary they merely adhere together, but with such an adhesive friction that the cable form is maintained even during various handlings, treatments, or the like.

The cable A can be taken off in zig-zag form, wound on to drums, or otherwise stapled; it can also easily be handled, and subjected to mechanical, physical, or chemical treatment processes. Finally the cable can also at any time be broken up again into individual thread bundles. For this purpose it is only necessary to pull on the ends 4|, 42' and 4|, 42", at the same time trying to bring these ends together. The crossthreads 4|, 42 push each other along in the course of the breaking up of the cable. The commencement of the breaking up of the cable canbe seen in Fig. 4.

Instead of the thread-shaped separating member 4|, 42, flat members, for example strips, may also. be provided. The other end of the cable, which may on occasion he as far as 10 kilometres away, may also: have a. similar pair. of. crossthreads: or CROSSJr-StI'iPSL passing. through. it. The

cross-threads: or cross-strips; advantageously have; a colour differentfromthatof the. individual. threads 4.0,. so that. the; separation point can be readily recognised.

In. the embodiment: illustrated in Figs. 5 to 7, the: cable A againv consists of a multiplicity 01.. individual. thread bundles 40", running parallel to one: another and. adheringto one another- At at least one. of the. ends of the cable a. dividing membelt in, the form of at strip 43 is provided... which passes: through. the cable in; windings and is adhesively connected at one. point: to. each of the individual threads. (See the: cross-section shown in. loosened form in Fig. 7..) The adhesive connection consists of a. sticking connection, the. cross-strip 43 for instance a. textile. band being made. adhesive on one side. for instance. by gum. It is: convenient for the parts of the. adhesiveside. of the strip 43 which. free externally, i. e. the parts of the windings lying free between them-- dividual threads and the free ends 43, 43" of the strip,fto be able not to have an adhesive action, in order that the strip shall not remain suspended elsewhere during manufacture, handling, treatment, or when taking oii the cable. This can be achieved in various ways in the course of the production of the thread cable, and suitable measures and means are explained in the description of Figs. 11 and 12. By pulling on the ends 43, 43 in an outward direction the cable can at anytime be broken up into the individual thread bundles (see Fig. 8). If desired the other end of the cable may also be traversed in similar manner by a strip.

The type and nature of the individual threads or thread bundles of the thread cable of the invention are restricted only by the requirement that the individual threads must extend throughout the whole length of the cable and must have a surface character which ensures adhesion of one to the other. In addition the adhesive ability may be improved by suitable measures, such as damping the threads, as already described.

The production of the textile intermediate product of the invention in the production of artificial spun threads will hereinafter be described by way of illustration.

Example I In a normal rayon spinning machine 5!, shown in Figs. 9 and 10, and having a large number of spinning points 52, the rayon thread bundles I, 2, 34, 35, after leaving the spinning trough to an apparatus b, are passed running parallel to one another over thread guides 54, 55. The apparatus b shown in Figs. 9 and 10 is so equipped that the even-numbered thread guides 54 and the odd-numbered thread guides 55 can be alternately raised and lowered. The thread guides 54 and 55 are guided in the frame of the apparatus b in such manner as to be vertically slideable and for example are articulated to twoarmed rocking levers 56 on the axle of which is mounted a pedal 51. By movement of this pedal, once in a clockwise direction and once in an anticlockwise direction, the thread guides 54 and 55 are alternately raised and lowered and thereby the individual threads I, 2 36,. 31 are twice shedded with the interposition of a shed. In each of these positions a preferably coloured transverse thread is introduced one close behind the other transversely to. the direction in which the thread bundles run, by means of a shuttle 58 i or the like. These cross-threads are cut off by a knife after they have passed through and they run on with the thread bundles. The latter then pass to the apparatus where they are grouped together under the pressure of rollers 59 to form the cable A. The thread cable formed in this manner but remaining subdivided by the transverse threads can now be subjected to various further treatments, for example stretching, impregnation, and the like, and finally be taken off, for example in zig-zag form. After attaining the desired length of cable, the latter is cut through. Shortly before the point of cutting a further pair of cross-threads may if desired be passed through by means of the apparatus 1), in which case the subsequent breaking up of the cable into individual thread bundles may also be efiected from the other end of the cable. These thread bundles may also for example be passed directly thereafter to a twisting machine, in order to make cord twine therefrom.

Example II In a spinning machine having a plurality of spinning points, each' of which carries a nozzle 8| (Figs. 11 and 12) having 2400 apertures, the spun slivers issuing from each nozzle, consisting of individual filaments of 1.5 denier, are divided by hand into four parts immediately on leaving the spinning trough, in such a manner that each spun sliver is first divided into two halves and each half divided into two approximately equal parts. As illustrated in Fig. 12, four thread bundles per nozzle are produced thereby, each of which has a total size of about 900 denier. The resulting individual thread bundles first run through thread guides 62 to an apparatus d and from the latter to an apparatus 0, similar to that illustrated in Figs. 9 and 10, which group together the thread bundles to form the cable A. At a point between the apparatus (1 and c, where the individual thread bundles still lie in a horizontal plane, but are already as close as possible to one another, a strip A3 of fabric, paper, or thelike which is adhesive on one side is placed against the thread bundles with the adhesive side against the latter. This can be effected from above by simply placing the strip on by hand, or else mechanically, for example from below by means of an apparatus .e, which consists of a stamper 65 suitable for carrying and applying the strip 43, said stamper being guided in the frame of the apparatus in such manner as to be vertically slideable and being articulated to the ends of rocking levers G6, the shaft 61 of which carries a pedal 88. By depres sion of the pedal 68 the stamper 65 with the strip 43 lying thereon is raised, and the latter is applied with its adhesive side against the thread bundles; At the same time a second strip can be applied from above, which covers the adhesive parts lying free between the thread bundles and the free ends of the strip. Instead of this intermediate strip, a substance which removes the adhesive between the thread bundles and at the ends of the strip may also be applied,

7 for example by spraying or sprinkling. The cable which is grouped together .in the apparatus 0,

- but is kept separated by the cross-strip 43, is

can be worked up directly to form a warp on a warp beam. The warp beam is then used to feed a sizing machine.
