A process for the drafting, interlacing and sizing of a series of continuous, thermoplastic yarns, which consist of filaments that are substantially parallel to each other, for the manufacture of chains or fractions wound on beams.
Description
This invention relates to a process for the pre-paration of chains or fractions wound on beams, made from continuous, completely-drafted and interlaced thermoplastic yarns, suitable for use on looms for the production oE tex-tile products of all types.
According to the present invention there is pro-vided a process for the preparation of warp or loom beams of continuous, syn-thetic complete-drafted yarns of thermo-plas-tic matexial selected from the group consisting of poly-esters, polyamides, polyethylene and polypropylene, said yearns being wound on weaving beams, suitable for all types of loom-produced textiles, said process comprising slmul-taneously and contemporaneously drafting a series of at least
According to the present invention there is pro-vided a process for the preparation of warp or loom beams of continuous, syn-thetic complete-drafted yarns of thermo-plas-tic matexial selected from the group consisting of poly-esters, polyamides, polyethylene and polypropylene, said yearns being wound on weaving beams, suitable for all types of loom-produced textiles, said process comprising slmul-taneously and contemporaneously drafting a series of at least
2~ yarns made of substan-tially parallel and partially drafted filaments by immersing said series of yarns in a vat containing a thermostatic liquid and subsequently subjecting said series of yarns while still humid to an interlacing treatment using a fluid jet, and then to a sizing treatment.
Thus in accordance with the present invention a series of continuous thermoplastic yarns, having filaments which are substantially parallel to each other and not com-pletely drafted, are simultaneously drafted when immersed in a thermosplastic liquid, then subjected to interlacing process on each individual yarn before being sized and then finally wound.
Conventional processes for the preparation of con-tinuous, thermoplastic-polymer yarns for tex-tile use involve spinning the filaments from the molten polymer, cooling them, combining them to form the yarn and then drafting the yarn.
Drafting orients the molecules of the filaments and thus gives them the required physical and mechanical - 1~ ~1 characteristics fox makins them suitable for textile use.
There are two techniques used in the known processes for obtaining filament interlacing. According to the more ~' ~ ~..
- la -Z4~)120 pertinent of the aforesaid techniques, ;he yarn produced during spinning is wound onto spoùls 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-acteristicst presumably due to the fact that each yarn is treated individually and is therefore subjected to a par-ticular temperature or particular mechanical setting re-garding its particular machine position.
According to another known process, the yarn is complete-ly drafted, right after being spun, by means of rollers having differential rotational speeds and then wound up on the cops. This process requires expensive spinning machines and, on the average, has a lower production ca-pacity than the above mentioned.
As is well known, thère are many cases where, in order to make the yarns suitable for loom use, where the mechani-cal stresses imposed in the loom operation could brrak 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 fil-aments with sizing agents, in accordance with the follow-;ng process.
The beams, upon which the previously warped yarns have been wound, are mounted on suppor~ creels. The properly-arranged and parallel yarns are passed through a special apparatus which includes an impregnation bath and squeez-ing rollers. The yarns are then dried by means of hot 40i2V
air, infrarec, radiati~n or ~r-a;ed cylinders, after which they are ~ound onto beans by winding machine.
A recent method, described by ;he Ap~licant's European Patent ~o. 91549, shows the possibility of co~lbining the two separate phases, drafting and sizing, into a single phase, thus providing obvious technical and economical advantages.
The scope of this invention is to obtain yarns for naking chains or fractions for textile use, with the yarns having high interfilament cchesion, especially as regards yarns containing a high number of filaments, by means of a fila-ment interlacing treatment combined with a sizing treat-ment.
The process relative to our invention, as mentioned pre-viously, permits the use of a starting yarn for the prepa-ration of the aforesaid chains or fractions for textile use which is not completely drafted, being as cbtained from the spinning process in accordance with kno~n tech-niques.
This present invention constitutes an ~dditional techni-cal develop!nent over and above that described in the 9p-plicant's afore-mentionPd ruropean Patent No. ~1549.
It consists in the carrying out of the ccm~llete draf~ing, separately, in a thermostatic bath, by mfans of tension rollers, followed immediately thereafter by the treatment of each individual yarn, while still wet, to interlacing process before entering the sizing bath.
The process, accc,rding to this invention, consists of the follow ng operations:
The not less than 24 cops mounted on the feed creel are each wound with yarn coming from the spinning rlachine.
The yarn is not completely drafted. The yarns unwind from 124~1~0 the cops at a constant ~ension and are kept parallel to each other by means of a comb guide. The yarns pass Lhrough a feed and support rolier system. The rollers have a constant peripheral velocity. ~ext, the yarns pass into a vat of thermostatic liquid, which is kept at a certain temperature so that the filan,enLs of the yarn can be drafted. The yarn leaves the vat and passes through a system of traction rollers which have a constant periphe-ral velocity that is greater than that of the feed rollers.
The system of feed and tensioning rollers can also be located in the vat of thetmostatic liquid.
The traction-roller system can also squeeze out all the excess liquid from the yarn. The desired simulLaneous action of drafting and molecular orientation of the indi-vidual filaments is obtained, between the feed and trac-tion rollers, by means of the combined action of the differential peripheral velocities, which generates fila-ment tension, and the softening of the polymer, due to the heat of the the~mostatic bath. Following the drafting and the squeezing out of the excess liquid, the still-wet yarns pass through the interlacing devices, which are standard devices and which entangle the fi`anents by means of a jet of fluid at high velocity.
These devices are arranged in a bank, are equal in number to that of the yarns and each one acts separately on each individual yarn.
Right after the yarn-interlacing phase, the yarns enter the sizing device. After being dried, the yarns are finally wound onto beams or similar devices by a winding machine.
Another possibility for feeding the apparatus consists in winding the yarns onto beams, small beams, large reels, -` - lZ~C~120 or any such similar device, us;ng a winding machine, and then feeding from these, rather than directly from the spools mounted on the creel.
In this case, it is possible tO unite several fractional beams at the entrance to the feed rollers from the draft-ing phase. The new method, the object of the present in-vention, whereby several continuous thermoplastic yarns are arranged parallel to each other, drafted si-nulta-neously and then interlaced before the sizing phase, permits a considerable cost saving, as compared to tradi-tional means. This is because of the complete elimination of the need for a preliminary drafting phase in which each individual yarn is drafted, either before or after the spinning collection, by using a drafting or drafting-twisting machine, according to the known processes men-tioned earlier.
Compared to the procedure described in the Applicant's European Patent No. 91549, this invention is different because of the fact that it also provides for the inter-]acing of the filaments prior to the sizing ODeration.In this manner, there is ~he great advar age of being able to cosiderably incrlase the velocity of the sizing process and, more important obtain a sized yarn having a great number of interlacing points, thus making the yarn suitable for use on very high speed, modern looms.
It has been found, in fact, that it is generally prefer-able to carry out interlacing on yarns that are still humid, so as to obtain better resulLs from the point of view of the connection effect between the filaments.
Another outstanding advantage provided by this invention consists in the possibiliLy of substituting the more usual types of interlacing devices with known voluminizing 4~:1120 devices, such as the known Taslan process~ for exari~ple, which used a high-velocity fluid jet. These devices obvi-ously provide interlacing and voluminization at the same time. The very great advantage of being able to conbine, in one plant, the drafting phase, voluminization phase, sizing phase and preparation of chains or fractions on weaving beams can, therefore, be obtained. With known procedures, in fact, the drafted yarn is fed into costly voluminizing machines.
This invention also provides, furthermore, an outstanding economic advantage by making it possible to obtain a better quality yarn, a better performing yarn in the loom and increased productivity with existing traditional equipment by adding the drafting and interlacing device tc the equipment. This modification causes no app~eciable change in standard warping systems, which remain substan-tially just as they are.
It has also been found, after having carried out numerous tests, that the fabrics obtained with the yarns treated in accordance with our new procedure have excellent compactness and uniformity characteristics and that ]oom down-time is substantially reduced, as compared to tho down-time normally occoring when using s~andard yarns.
This invention is further illustrated by the following non-limiting examples:
EXAMPLE l_ 100 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 Filamen~ cross-section: circular - -- lZ401Z0 Breaking lGad: 330 grams Ultimate e]ongation: 156/o Theoretical residual draft: 1.628 (1?7/78) The yarns are warped under a tension of 10 g, passing them through the blades of a rectilinear comb. The yarns are anchored and dragged with a tension of 10 g by a three-roller system, which roll together at a constant peripheral speed of 148 meters/min.
The yarns are then immersed in a vat of demineralized water, which is held at a constant temperature of 80C.
~ system of three drafting and squeezing cylinders, which rotate together at a constant peripheral speed of 250 meters~min., acts simultaneously on all th~ yarns, giving them a draft-to-feed ratio of 1.689.
Upon leaving the drafting and squeezing cyiinders, the yarns pass through the interlacing jets, which are fed by compressed air under 3 Atm of pressure.
rhe yarns are then immersed in a vat containing a hot-glue bath, consisting of a 10b water solution of Adex-Twe acrylic glue made by the Cesalpinia company, andmaintained at a constant temperature of 90C.
The sizing speed is kept slightly under 240 meters/min., so as to obtain a certain amount of yarn swelling, which favors the absorption of sizing.
The yarns are then dried by passing them through hot-air ovens. The yarns then receive thermal fixing by passing into contact with steam-heated cylinders, the temperature of the cylinders ranging from 105C to 90C from the first one to the last one.
~hen leaving the fixing cylinders, the yarns are wound on beams measuring 1800 mm in height and in six frac-tions, each meaSUring 12000 m in length.
The average characteristics of the drafted and glued yarns thus obtained are as follows:
Count: 79.1 Dtex Breaking strength: 319 g Ultimate elongation: 34%
Shrinkage in boiling water: about 2%
Glue remaining on yarn: 8/8.5%
During the next phase the 6 glued fractions are wound on a weaving beam, measuring 1550 mm in height, for a total of 600C yarns.
The beam is loaded onto a water loom and wafted with tex-turized polyester yarn having a count of 56 Dtex and 24 filaments, at a speed of 490 beats/min., with a cloth weave and a density of 30 wefts/cm.
The fabric is then dyed in a jet-type cord-dyeing machine.
Dispers Blue Color Index 056 dispersed dye is used.
The fabric is centrifuged, dried in hot air, passed through a stenter machine and thermo-fixed at 180C at - 25 meters/min. ~he obtained fabric has a height of 140 cm.
Specular inspection on a black ~able, for revealing fabric defects, reveals high uniformity and corrlpac~ness of the chained yarns with lucid yarns being totally absent.
_ _______ _ The same procedure is used as in the foregoing example except that 1160 cops ot the same yarn are loaded onto the creel and 8 weaving beams, having a height of 44 inches each, are wound with 15000 m of chain lengths each.
The 8 weaving beams are then loaded onto a chain-type, rectilinear knitting frame.
Dyeing and fixing operations are then carried out on the obtained knitted fabric, as done in the previous example.
Examination by passing the fabric under the specular 4~)~'20 instrument reveals perfect evenness of weave and dye horDo~eneity.
Thus in accordance with the present invention a series of continuous thermoplastic yarns, having filaments which are substantially parallel to each other and not com-pletely drafted, are simultaneously drafted when immersed in a thermosplastic liquid, then subjected to interlacing process on each individual yarn before being sized and then finally wound.
