Description

Patented Feb. 14, 1950 UNITED FATQ E oral-cs Carro'lliF.
:E. I. du iPont, de.;-Nemurs & Company, Wilmington, Bel -a-c 0rporation== of. .l)elaware No'DraWing. Application June 14,194:6,
" Serial NOKGTGEQQLEO- This invention relates to :the dressing of textil fib er-s, filaments and yarns and more particularly like.
7 "Impreparation for subsequent operationssuch as spoolin'g, throwing, dyeing, etc., and in some "cases to improve the appearance and hand-git is customary to dress the freshly spun yarn with a finish compos'ition which generally comprises one or a mixture of :oils such as mineral oils, "dryingoilsanim'al oils, vegetable oils, sulfonated lution, emulsion or dispersion. This treatment serves one or a number of the following purposesz -'case of cellulose acetate) to facilitate dyeing 20f --the yarn package, to increase tensile-strength, tenacity weight 'of' the yarn to some ex-tent, "to impart to {the 'yarn luster, -softness and/or flexibility, to "bond-the fibersor filaments of the yarn, etc. 'The' exact composition "employed depends, of course, on the :"effects desired, but it "ismoSt-difificulttO' formulate a composition which 'is's'atisiactory inevery respect'and it is especially *difllcu lt to formulatea'finish compositionwhich will notadversely affect the package 'orcake'f orto:improved finish compositions :ior fibers, fila- "merits-and yarns of cellulose acetate and the :Briefiy :sta'ted therefore, any invention .com-
-:prises; a"pply1ing :to freshly formed artificial Iyarn,
derived from any source, fr0m-0;005% to 0.075%, based on the dry Weight of the treated yarn, of a polyvinyl alcohol contained in an aqueous oil emulsion-finish composition.
The term polyvinyl alcohol appearing herein is used in its accepted trade sense and denotes the water-soluble types of partially saponified and fully saponified polyvinyl'a'cet'ate. For purposes of the present invention, it is preferred'to use .,-polyvinyl alcohols of low viscosity, 1. e., polyvinyl oils; antioxidants, wetting fagents, anti-static agents, sizes anda variety of other materials, both organic and inorganic, commonly in aqueous soalcohols havinga maximum solution viscosity of to centipoises in 4% aqueous solution-at C. The amount of polyvinyl alcohol incor- -porated in the ,yarn must be maintained within "to prevent abrasion 'or'bre'akage =of-fthe yarn -during twisting -or spooling, to counteract or 'offset the effects of 1 static charges (particularlyin' the thezlimitszof -.0-.O053%- to 0.075% by weight, based on the dry Weight of the treated yarn. If more than 0.075% of polyvinyl alcohol is used, poor cake formation occurs, there is sticking to under layers (especially after aging), crocking on guides and, in general, the results are unsatisfactory. The use of polyvinyl alcohol in accordance with the principles of this inventionis not to be confusedwith its use as a yarn size, for in the present case, the amount of polyvinyl alcohol is insufllmation 'of headless packages.
Anobject'df thisinvention therefore istoprovide improved compositions with which to dress textilenbers, filaments and yarns.
Another object is to provide aqueous finish emulsions which will produce substantial im- *provemen'tsin yarn frictional properties and yarn quality.
Still another object is to treat cellulose acetate.yarn whereby to secure better package forcient to give asizing eiiect; i, e., there is 'no filament or thread-to-thread adhesion as in sized :yarn. Moreover, the advantages of sizing are ,generally related only to dried yarn, Whereas the advantages of this invention are realized more particularly withyarn that has not been submitted to a drying action.
As a finish or lubricant composition, there may be employedany of the usual aqueous emulsions .;containing mineral, vegetable and/or animal oil,
sulfonated-oils, amine salts, anti-static agents,
vMpolyhydric alcohols, etc. which have'hereto'fore -beenused in the dressing of textile fibers, filaments and yarns. The concentration of polyivinyl alcohol in the dressing composition will .mation and yarn of improved quality. L'Ihese' andother objects will more clearly appear hereinafter.
Unexpectedly, I have found that the presence on yarn of a relatively small amount of polyvinyl alcohol, applied as a constituent of the usual aqueous oil emulsion type of dressing,.works a remarkable improvement in the quality and handling characteristics of the yarns and, in particular, imparts to the yarn a lower coeffioient of friction.
depend, of'course, upon the amount of composition applied to the yarn and should be adjusted to provide an amount of polyvinyl alcohol in the yarnwithin the-limits hereinabove specified.
To more viu'lly illustrate the practice and advantages of this invention, the following example is given. Parts and percentage composition are by weight unless otherwise indicated.
Example I '75 denier, 50 filament, 3,0 turn cellulose acetate yarn of 54.5% combined acetic acid containing 3.4% (calculated as solids) of a finish of the following composition:
40 solution of a 1 E565 salt of phenyl phenate) 1.4 Polyvinyl alcohol (86-89% saponified; sap
onification No. 127-157; viscosity-5 centipoises) 0.5
(applied as a water emulsion containing 22.7% solids) was tube wound, without drying, into three pound packages. Compared with three pound packages of identical yarn wound in the same way and dressed with the same relative amount of a finish composition (regular finish) containing no polyvinyl alcohol but otherwise identical with that specified above, the following In addition, the package formation was excellent, and there was no objectionable crocking on guide or roll surfaces.
Example II 75 denier, 50 filament, 3.0 turn cellulose acetate yarn of 54.51% combined acetic acid containing about 3.4% (calculated as solids) of a finish of the following composition:
Percent Butyl acetyl ricinoleate 10.0 Triethanola-mine oleate 22.3 Sulfonated peanut oil 10.0 White mineral oil (#43) 42.2 Propylene glycol 3.0 White mineral oil (#105) 6.9 Diethylcyclohexylamino lauryl sulfate 4.5 Stenol (cetyl and stearyl alcohols) 1.1
prepared as a 25% aqueous emulsion to which is added 0.75% (calculated on the dry weight of the total finish solids) of polyvinyl alcohol (86-89% saponified, saponification No. 127-157, viscosity-5 centipoises), was tube wound, as in the previous example, without drying, into threepound packages.
Polyvinyl R Alcohol Finish Finish Coeflicient of friction 0. 54 0. Per cent Reject packages 6. 4 7. 9 Warp Defects/Million Thte Major Defects 144 353 Minor Defects. 614 1428 Total Defects. 758 1796 Knots/34b. Cone... 3.6 3.7 Per cent l-knot Con 19 12. 3
Although this invention has been specifically illustrated in connection with the tube winding of headless packages of cellulose acetate yarn, it will be obvious to those skilled in the textile yarn art that it is applicable with like effect to other operations such as skeining, throwing, etc., and may be applied with advantage to textile fibers, filaments, yarn or threads of any other material, such as regenerated cellulose from viscose, cuprammonium cellulose, cellulose ethers or other cellulose derivatives, vinyl polymers, nylon, poly acrylonitrile, mercerized cotton, etc.
It will be apparent from the foregoing that this invention not only enables the production of yarn of improved quality, but, in addition, by reason of fewer rejects, lessened gumming of guides, rolls, etc., it contributes materially to the economy of such production. Moreover, it has been observed that the presence of small amounts of polyvinyl alcohol serves, in general, to stabilize the finish composition and to improve roll coverage Where roll applicators are employed.
As many widely different embodiments can be made without departing from the spirit and scope of this invention, it is to be understood that the invention is not restricted in any way except as defined in the appended claims.
I claim:
1. In the process of conditioning textile filaments of synthetic, organic, filament-forming material wherein the freshly formed filament is dressed with an oil-containing, aqueous finish composition, the improvement which comprises incorporating in said finish composition suificient polyvinyl alcohol to deposit on the filament from 0.005% to 0.075% by weight, based on the weight of the filament, of polyvinyl alcohol.
2. In the process of conditioning cellulose acetate filaments wherein the freshly formed filament is dressed with an oil-containing, aqueous finish composition, the improvement which comprises incorporating in said finish composition sufiicient polyvinyl alcohol to deposit on the filament from 0.005% to 0.075% by weight, based on the weight of the filament, of polyvinyl alcohol.
