TEXTILE l Filed April l 1ol 1929 maar r e y i@ Patented May 13, v1930 UNITI-:n STATES .PATENT OFFICE FULTON RINDGE, F WARE, MASSACHUSETTS, .ASSIGNOR OF ONE-HALF TO EDWARD C. `BROWN,'OF WATERTOWN', MASSACHUSETTS i TEXTILE Application mea April/1o,
This invention pertains to textile manufactureand more particularly to a process` heddle and other guiding and positioning elements, tends to cause frequent breakage. Moreover, in dealing with soft or fibrous yarns, especially those Whose iibers tend to @a kink, curl, or intertwine, for instance Woolen yarns, great diiiculty is experienced through the entanglement of the fibersl of one yarn With those of adjacent yarns, which causes slubs, knots, and breakage during the Weaving and preliminary processes and results in floats in the Woven fabric.7 To avoid these diiiculties, the yarn is commonly, drawn through a-bath of starch or glue size and dried before Weaving, and in lthus treating the wyarn, every eiort is'made tocause the size to penetrate the'yarn completely, so as to stick the individual fibers ofthe yarn together. While the size commonly employed does not greatly vincrease the tensile strength of the yarn, it unites the fibers so that the yarn is not so readily roughened or abraided by heddles and guides. While this mode of treating the yarn has been known and practiced for many years it has certain practical disadvantages among which in particular may be mentioned the great loss of time in drying.
the sized yarn; the initial oost and operating expense of usual drying apparatus, 1n which a large amount of heat is consumed; and
l thedanger from mildew when yarn, so sized,
is stored for any considerable time In accordance with the present invention I provide ortemporarily ut rmly binding together the outer/'constituent fibers of the I yarn, thereby in eect to form a sheath which with the rubbing of the yarn against the' 1929. Serial No. 354,063. l
protects the inner fibers and minimizes abrasion during Weaving, but reach this result without employing heat for drying the yarn and by a treatment which takes but a small fraction of the time required for the usual Asizing operation. treated has' greatly increased tensile strength as compared with varn sized by usual methods butvvithout unduly impairing its normal flexibility; its surface bers are so united and protected that they do not snarl, bunch, or tangle readily; it will not mildew; and it preserves its internalmoisture, oil, or grease indefinitely.
To this -end I employ as the treating medium a substance which possesses strengthening and gloss imparting qualities; which dries almost instantaneously at usual room temperatures; and which forms a thin, tough and flexible protective outer sheath about the inner bers. For best results apply this material in the form of a ine mist-like spray through Which the yarn passes, and which is deposited upon the outer fibers, after substantial penetration into the interior of the yarn, and which coats and binds in the outer fibers to form a more or less continuous but extremely thin layer or sheath from Which the solvent evaporates immediately upon ex-` posure to the air. Preferably l employ one of the quick drying cellulose lacquers (of which pyrpxyline may be cited on aspeciiic example) and which usually comprise a cellulose ester of nitric or acetic acid, extended in a highly volatile solvent, for example acetone or amyl acetate. This lacquer (for this p-urpose ordinarily uncolored) may be thinned down to a constituency suitable for atomization by the particular means employed for this purpose, and after evaporation of the solvent leaves the yarn with. an extremely thin but dry and non-sticky, toughand fiexible sheath in which the outer bers are rmly bound together. vThe preferred method ,of producing the spray or mist of coating materialvdoes not involve the use .of air or other gaseous medium at high pressure, .and thus penetration of the interior of thel yarn by the coating material is substantially prevented and incidentally the troubles incident to leakage of the coating solution or its solvent into the surrounding area are avoided and substantial economy in the amount of coating material required results. This coating material, unlike the usual starch size, does not penetrate the yarn to any substantial depth, but by reason of its toughness greatly strengthens the yarn, provides a glossy surface protecting the yarn against abrasion, from snarling, mildew, and breakage, and tends to minimize the formation of oats in weaving. Since this coating is of vegetable origin, it is completely removed from woolen (including worsted) or silk fabrics in the process of carbonizing,'and is readily removable from cotton by proper solvents without substantial detriment to the yarn itself, and since-the coating Ais very thin, ordinary laundering is usually sufficient to remove it vz--thus the practice of this process need not substantially affect the appearance or feel of the finished fabric.
. In the accompanying drawings I have diagrammatically illustrated certain apparatus that, the drawings are merely illustrative and not intended to limit the invention.
In the drawings:
Fig. 1 is a fragmentary diagrammatic side elevation, to greatly enlarged scale, of an idealistic spun yarn after treatment in accordance with the present invention;
Fig. 2 is a sectional view on the line 2 2 of Fig. l;
Fig. 3 is a diagrammatic cross section to large scale of a woven fabric having its warp yarns prepared in accordancewith the present invention;
Fig. 4 is a diagrammatic side elevation, partly in section, of apparatus suitable for use in the practice of this process;
Fig. 5 is a diagrammatic plan View of the apparatus of Fig. 4; and
Fig. 6 is a side elevation, to largerlscale, of ille atzomizing element of the device 'shown in Referring to the drawings, the numeral 1 designates a 'spun yarn comprising a plurality of textile fibers twisted together in the usual manner to form a moreor less cylindrical strand. Fol-.convenience in illustration the yarnof Fig. 1 is shown as of idealistic perfection, having all of its constituent fibers laid smooth, close, and substantially parallel, and
being without slubs, loose ends or other common defects. As shown in Fi 1 this yarn sheath. Since the actual yarn is not truly cylindrical and since its constituent bers are not all parallel but sometimes cross, kink or points.
snarl, and since in somev yarns, especially woolen and worsted, there are more or less short projecting ends, etc., the coated yarn does not in practice, when viewed under the microscope, present the smooth external appearance of Fig. 1 but is more or less rough and uneven, being somewhat suggestive in appearance of a twig which has been exposed to a freezing fog or mist, the original irregulari-` ties of the uncoated yarn appearing as smooth, glossy lumps or rounded protuberances and the ends of the fibers being agglutinated and encased so that they appear as relatively short, stiff stubsnot readily entangled with those of adjacent yarns. While this outer sheath or coating is substantially continuous, it may have small fissures or openings at irregular intervals, .due to the failure of the coating material completely to coalesce at all Such a coating, consisting of a dried cellulose lacquer, for example pyroxyli'ne, deposited from a mist or spray of the fluid lacquer, While suflicient to bind the fibers of the yarn together; to impart great additional strength to the yarn; and to resist separation of the fibers by abrasion in the weaving operation, nevertheless substantially disappears 'when the woven fabric is suitably treated.
In applying the coating to the yarn I may employ apparatus such as shown in Figs. 4, 5 and 6. This apparatus comprises a creel 4 adapted to support a great number of cheeses, spools, cops or the like, indicated at 5, providing masses of spun yarn from which the yarns are drawn'ofi through a reed 6 and thence to a beam 7 upon which they are wound, the yarns intermediate the reed 6 and the beam 7 forming a substantially horizontal sheet W. This sheet of yarns passes through the coating apparatus A which preferably consists of a closed tank or casing having openings 9 and10 in its opposite side walls for thepassage of the sheet of yarns and containin a shaft 11 driven at high speed by suitablia means (not shown) and provided with aseries of disks 12 adapted to dip into a bodypf the fluid lacquer C in the receptacle andby centrifugal action to atomize thismaterial inthe form of a fine mist or spray in the upper part of the casing. This" type of atomizing apparatus is highly desirable since it does not create a pressure in the tank which would force the-coating material into the interior of the yarn while, furthermore, it avoids leakage of the solvent vapor into the surrounding air,- such as results when pressurespraying or the like is employed. Preferably the casing is provided with a drain pipe 13 which delivers to the. intake of a circulating pump 14 which returns the fluid lacquerv to the casing. Suitable supply connections 16 are provided for delivering a fresh supply of coating material to the tank when needed. i I
As the sheet W of yarns passes' through the upper part of the tank or casing, the mist-like particles of the lacquer deposit upon the exposed exterior fibers of the yarn, the particles or droplets which deposit upon adjacent fibers coalesce so as to form a film of sufficient continuity to bind in these outer fibers and thus protect the inner fibers, although, as above stated, the incomplete coalesce'nce may leave small, fissures or openings in the coating or sheath at irregular intervals. The yarn now passes out through the opening 10, but Without contact with guides or other elements disturb the sheath of fluid coating material, and upon exposure to the air at the point 18, the highly volatile solvent' employed evaporates almost instantly leaving the yarn with a dry, non-sticky, tough coating as above described. The treated yarn is Wound upon the beam 7 or other suitable support, and may now be employed for any desired purpose, for example, as a wea-ving warp, being used with weft yarns similarly prepared or with ordinary wefts as desired. It is to benoted that the yarn after receiving its coating,` does not engage guide or squeeze rollers before the coating is substantiallydry, and thus its normal substantially cylindrical shape, resulting from the spinning operation, is substantially preserved. In Fig. 3 I havey illustrated a fabric woven-by the use of treated warp yarns lw and ordinary Wefts a. l
After weaving, this fabric may be subjected to appropriate finishing operations, such, for example, as carbonization, washing with soap or weak alkaline solutions, etc. upon the completion of which it is found that the coating lhas substantially disappeared, although during the weaving the coating strengthens and protects the yarn so that but little,`if any, warp breakage occurs. l
Preferably the yarns are treated bythe present method as soon as possible after spinning, thus retaining the original moisture or oil taken up by the fiber during the preliminary steps in the textile process, thus preserving the fiexibility of the fiber and preventing it from becoming harsh or brittle,l
while the sheathing prevents abrasion of the formation of iy and slubs throughout all subsequent stages of manufacture.
While I have herein disclosed one desirable type of apparatus suitable for use in atomizing the adhesive and for presenting the yarn for contact with the mist or spray produced by the atomizing means, I wish it to be understood that the invention 'is not necessarily limited to the employment of the apparatus herein described and illustrated but that any suitable means may be used for the purpose.`
'Moreoven while the method of applying the coating material to theyarns as herein dis- 'closed is well suited for use with cellulose lacquers as described, it is contemplated that this method of applying of the coatin material by atomization may also be foun useful in applying adhesives of other types to the yarn, since by these means a very thin uniform coating is obtained. In this connection 1t may be noted that by applying the coating in the form of a mist or spray, there is a less penetration of the yarn by the coating material than in under usual practice so that while the surface of the yarn is protected and its constituent fibers are sheathed and confined so as to impart a maximum strength to the yarn the yarn still remains flexible, and great economy in the use of the material is effected.
I claim:

That method of treating textile yarn preparatory to its manufacture into cloth which comprises as steps depositing upon the surface of the yarn a thin coating of a fluid adhesive comprising a cellulose ester of nitric acid extended in a highly volatile solvent and substantially free from oily substances, and
