This invention relates to a method for the preparation of chains or fractions wound on beams, which comprise continuous thermoplastic yarns which are completely drafted and interlaced and suitable for use on looms for the production of textile pro-ducts of all types.
According to the present invention there is provided aprocess for the preparation of chains or fractions of chains of continuous, synthetic completely drawn yarns of thermoplastic material selected from the group consisting of polyester, polyamide, polyethy]ene and polypropylene, said chains being wound on weaving beams, in which process a series of at least 24 yarns made of substantially parallel and partially drawn fila-ments are simultaneously drawn when immersed in a vat containing a thermostatic llquid and sub;ected to a shrinkage and thermoset-ting treatment before being wound on a weaving beam, the drawing of the yarns in the vat being carried out in the absence of a sizlng agent, and after the drawing step and before the shrinkage and thermosetting treatment, the yarns being subjected to an interlacing treatment using fluid jets, said interlacing treat-ment being carried out while the yarns are still wet.
Thus, the method of the present invention comprises a series of continuous thermoplastic yarns, having filaments which are substantially parallel to each other and not completely drafted, are simultaneously drafted when immersed in a thermo-static liguid and that each yarn is subjected to interlacing pro-cess prior to final winding.
The known processes for the preparation of continuous, thermoplastic-polymer yarns for textile use involve spinning the filaments from the molten polymer, cooling them, combining them to form the yarn and then drafting the yarn.

- 2 12S437'~
more pertinent process, the yarn produced during spinning is wound onto spools in an incompletely-drafted state.
Complete drafting of the yarn takes place in a subsequent phase by means of a special drafting or drafting-twisting machine, which has several positions, each of which act-ing on one individual yarn. These machines do not readi-ly permit the obtaining of perfectly constant yarn char-acteristics, presumably due to the fact that each yarn is treated individually and is therefore subjected to a particular temperature or particular mechanical setting regarding its particular machine position.
As is well known, there are many cases where, in order to make the yarns suitable for loom use, where the mechan-ical stresses imposed in the loom operation could break the individual filaments, the yarns coming off the draft-ing or drafting-twisting machine are subjected to a sizing operation, which consists of impregnating the filaments with a special sizing agent, in accordance with this process: ~
The beams, upon which the previously warped ~arns have been wound, are mounted on support creels.
The properly arranged and parallel yarns are passed through a special apparatus which includes an impregna-tion vat and squeezing rollers. The yarns are then dried by means of hot air, infrared radiation or heated cylinders, after which they are wound onto beams by a winding machine.
A recent method, described by the Applicant's European Patent No. 91549, shows the'possibility of combininp the' two separate phases, drafting and sizing, into a single phase, thus proving obvious technical and econo~ical advantages.
i'~S43~
AS stated prevlously, the method given in this inven-tion allows the use of a yarn which is not completely drafted, as obtalned by spinning in accordance with the known technique, as the starting yarn for the preparation of the aforesaid chains or fractions for textile use. This present invention constitutes an additional technical development over and above that described in the Applicant's aforementloned European Patent No. 91549. It consists in the elimination of the need for a sizing agent in the thermostatic bath. The sizing treatment is replaced by an inter-lacing process, wh~ch is applied to each individual yarn at theexit side of the thermostatic bath. It can be located, however, even before the drafting phase; for example, on the feed creel.
The process of this invention includes the following operations The not less than 24 cops mounted on the feed creel are each would with yarn coming from the spinning machine. The yarn is not completely drafted. The yarn unwind from the cops at a constant tension and are kept parallel to each other by means of a comb gulde. The yarns pass through a feed and support roller system. The rollers have a constant peripheral velocity. Next, the yarns pass into a vat of thermostatic liquid, which is kept at a certain temperature so that the filaments of the yarn can be drafted. The yarn leaves the vat and passes through a system of ~-~ traction rollers which have a constant peripheral velocity that ,' is greater than that of the feed rollers. The rollers of the traction system are also designed for squeezing out any excess water adhering to the yarn. The desired drafting and molecular orientation of the individual filaments is obtained, between the feed - 4 ~ 125437'~
and traction rollers, by means of the combined action of the differential peripheral velocities, which eenerates tension, and the softening of the polymer, due to the heat of the bath. Following the drafting operation, the yarns then pass through interlacing devices, which are of known design and which are used to entangle the filaments by the action of high-speed fluid jets. These devices are arrenged in banks and, there being one for each yarn, the yarns are acted upon individually. In certain cases, it is preferable to subject the yarns to a preliminary inter-lacing treatment prior tp the drafting operation.
In these cases, the interlacing devices can be convenient-ly mounted on the feed creel.
After the drafting bath and either before or after the interlacing phase, the yarns can be dried by passing them through suitable ovens and/or heated cylinders.
The yarn is then wound onto beams or similar devices, using a winding machine.
Another possibility for feeding the apparatus consists in winding the yarns onto beams, small beams, large reels, or any such similar device, using a winding machine, and ~hen feeding from these, rather than directly from the spools mounted on the creel.
In this case, it is also possible to unite several frac-tional beams at the entrance to the feed rollers from thedrafting phase. The new method described in this inven-tion - whereby several continuous thermoplastic yarns are arranged parallel to each other, drafted simultaneously and theninterlaced - permits-a cons-derable cost-savings, as compared to traditional process mentioned earlier.
This is because the process permits the complete elimina-tion of the preliminary drafting phase in which each _ 5 _ ~ ~S437~
individual yarn is drafted, =i~her berore or after the spinning operation, by using a drafting or drafting-twist-ing machine.
Compared to the procedure described in the Appljcant's European Patent No. 91549, this invention provides the considerable advantage of being able to do away with the need for a sizing agent, substituting it - in practical terms - with an interlacing process.
In general it has been found preferable to carry ou~
interlacing when the yarn material is still wet, because better yarn interconnection is obtained in this manner.
Another outstanding advantage provided by this invention consists in the possibility of substituting the More usual types of interlacing devices with known voluminizing devices, such as the known Taslan process, for e~ample, which uses a high-velocity fluid jet. These devices obvi-ously provide interlacing and voluMinization at the same time. The very great advanta3e of being able to combine the drafting operation, the voluminization operation and the preparation of chains or fractions on weaving beams can, therefore, be obtained. With known procedures, ir fact, the drafted yarn is fed into costly voluminizing machines.
This invention also provides another outstanding advan-~5 tage; that is, a further reduction of operational costbecause of the elimination of the need for desizing the end product, which would otherwise have to be desized by using costly desizing processes.
These advantages are obtained, furthermore, without having to substantially modify the standard systems of operation, these remaining essentially the same.
After having carried out a long series of tests, we have 12S437;~
shown that the fabrics woven with the yarns produced with our new method have excellent compactness and uniformity characteristics.
This invention is further illustrated by the following non-limiting examDles:
__ _______ 1000 cops of partially-oriented, lucid, polyester yarn (POY), having the following characteristics, are loaded onto a warping feed creel.
Count: 127 Dtex Number of filaments: 24 Filament cross-section: circular Breaking load: 330 grams Ultimate elongation: 156%
Theoretical residual draft: 1.628 (127/78) The yarns are interlaced in the feed creel and then warped under a tension of 10 grams, passing through the blades of a rectilinear comb.
The yarns are anchored and dragged with a tension of 10 grams by a 3-roller system, which rotate together at a constant peripheral speed of 130 meters/ min.
The yarns are then immersed in a vat of demineralized water, which is held at a constant temperature of 80C.
A system of three drafting and squeezing cylinders, which rotate together at a constant peripheral speed of 220 meters/min., acts simultaneously on all the yarns, giving them a draft to feed ratio of 1.692.
Upon leaving the drafting and squeezing cylinders, the yarns pass through the interlacing jets, which are fed by compressed air under 3 Atm of pressure. The interlaced yarns are then dried and set by coming into contact with seven rotating cylinders, which are heated by steam 7 _ 125437~
and kcpt at temperature from 150C, the first cylinder, to 90C, the last.
The speed of the heated cylinders is kept slightly under 220 m/min., so as to allow a certain amount of shrinkage of yarn lerlgth before setting.
When leaving ~he setting cylinders, ~he yarns are wound on beams measuring 1800 mm in height and in six fractions, each measuring 16000 meters in length.
The average characteristics of the drafted and interlaced yarns thus obtained are as follows:
Count: 82 Dtex Breaking strength: 321 grams Ultimate elongation: 34/O
Shrinkage in boiling water: about 2%
During the next phase, the six fractions are wound on weaving beams measuring 1550 mm in height, making a total of 6000 strands of yarn.
A beam is loaded onto a water loom and wefted with tex-turized polyester yarn having a count of 78 Dtex and 24 filaments, at a speed of 410 beats/min., with a cloth weave and a density of 24 wefts/cm.
The fabric is then dyed in a jet-type cord-dyeing ma-chine. Diespers Blue Color Index 056 dispersed dye is used.
2S The fabric is centrifuged, dried in hot air, passed through a stenter machine and thermo-fixed at 180C at 25 m/min. The obtained fabric has a height of 140 cm.
Specular inspection on a black table, for revealing fabric defects, reveals high uniformity and compactness~
of the chained yarns with lucid yarns being totally absent.
- 8 _ 12S437~
EXAMPLE_2_ The same procedure is used as in the foregoing example except that 1160 cops of the same yarn are loaded onto the creel and eight weaving beams, having a height of 44 inches each, are wound with 15000 m chain lengths each.
The eight weaving beams are loaded onto a chain-type, rectilinear knitting frame.
Dyeing operations are finally carried out on the obtained kn;tted fabric as done in the foregoing example.
Examination by passing the fabric under the specular in-strument reveals perfect evenness of weave and, in parti-cular, perfect dyeing homogeneity.
more pertinent process, the yarn produced during spinning is wound onto spools in an incompletely-drafted state.
Complete drafting of the yarn takes place in a subsequent phase by means of a special drafting or drafting-twisting machine, which has several positions, each of which act-ing on one individual yarn. These machines do not readi-ly permit the obtaining of perfectly constant yarn char-acteristics, presumably due to the fact that each yarn is treated individually and is therefore subjected to a particular temperature or particular mechanical setting regarding its particular machine position.
