This invention relates to the finishing of textile materials. More particularly the invention relates to the coating or impregnating of textile materials, such as yarns, filaments, fibers, fabrics, and the like, whether natural, artificial, or synthetic, with addition products formed by reacting an amine with a sulfone-activated ethylenic compound, i. e., compounds having ethylenic (C C) linkages which are activated by a sulfone SO2) group adjacent said ethylenic linkages, in order to enhance the water retentive and wet elongation properties of the textile materials, as well as to stabilize such materials against repeated washings and to set crimp therein when the textile materials are, or are formed from, crimped fibers.
While the present invention is applicable to the treatment or finishing f yarns,- filaments, fibers, fabrics, and the like, whether natural, cel'- lulosic, artificial, or synthetic, for purposes of illustration the same will be described as it is applicable to the treatment of rayon yarns, etc., formed by the regeneration of cellulose from viscose solutions in conventional manner, it being understood that the invention is only to be limited as the same is defined in the appended claims. Cellulosic as used herein is intended to include regenerated cellulose, and cellulose derivatives, such as cellulose esters and ethers, for example, nitrocellulose, cellulose acetate, ethyl cellulose, hydroxy ethyl cellulose, which contain a reactive hydroxyl group.
It is well known to impregnate rayon with many types of compounds that form resins, for
various and sundry purposes. These resins, how-' means have been proposed such as numerous impregnating agents, coating agents, and the like. While these agents have accomplished their purpose to a certain extent, they have not proved en- 'tirely satisfactory and there still is room for pregnate yarns, fibersffilaments, fabrics, and the like, whether natural, cellulosic, artificial, or
synthetic, with a polymerizable compound formed by the reaction of urea and a sulfone activated ethylenic compound.
It is another object of the present invention L to treat cellulosic textile materials with a resin forming compound which will react with the cellulose contained therein.
Other objects and advantages of the present invention will be obvious from the following description of the same which is merely intended to be illustrative and not limitative.
In general, the objects of the present invention are accomplishedby immersing the textile ma- I terial to be treated, in an aqueous bath of a resin ever, are simply deposited in the base material and do not react withthe constituents of the material: This is evidenced by the fact that such resins may be dissolved out' of the material by theirusual solvents, for example, alcohol, or a mixture of alcohol and benzene. The general type of resins that have been employed in the past are those derived from condensation prodget; of phenol, urea and the like with formaldey e. polymerization process proceeds so rapidly that a compound formation with the base material, such as cellulose, cannot take place and therefore the resins do not react with the cellulose.
Workers in the rayon industry are continually striving to find improved ways to reduce the Water retentive property of rayon as Well as to stabilize fabrics formed therefrom against repeated washing and to find some improved means to set the crimp in textile materials. Various However in these pes of resins, the
forming material, formed by the reaction of urea with a sulfone-activated ethylenic compound, removing the excess solution, and then heatingthe impregnated textile material to dry. the same and to cure or polymerize the resinforming material or addition product therein. The preparation of the resin forming materials and addition products within the purviewof the instant invention are described in my copending application S. N. 177,344, filed August 2, 1950,
entitled fiAddition Products of an Amine and Sulfone-Activated Ethylenic Compounds.

Preferably, a catalyst is added to the. solution just prior to application in order to} facilitate polymerization of the compound when the rayon or other textile material is heated. Suitable catalysts for the polymerization reaction are any base or alkali which is unreactive with the resin, for example, there may be employed quaternary ammonium hydroxides, the alkali and" alkaline earth metals, their oxides, hydrides,
and carbonates, such as sodium hydroxide,
sodium ethoxide, sodium. hydride, phenyl lithium, potassium carbonate, metallic sodium, barium, calcium, etc, trimethyl benz yl ammonium hydroxide, tetramethyl ammonium hydroxide, and the like, etc. The amount of catalyst necessary is small, e. g. .091-170 or more.
The excess solution is removed in any eonvenient manner and the impregnated material is then heated at a. temperature. within the range of 75-260 C. for a period, such as of 30 minutes ing compounds which have following examples are understood that the invention is not to be limited 'washing and to set the. crimp therein.
or greater, depending upon the degree of polymerization desired. Products treated in such a manner show a decrease in water retention of approximately 50-60%, In addition, the products are stabilized against repeated washing and the crimp is set when the products comprise crimped fibers. Water retention as used herein is defined. as the percentage of water retained by the fiber or" other textile material after centrifuging under standard conditions and is based on the conditioned weight of the material.
The. treating solution may be applied to the textile material in any of several ways. Staple fibers may be dipped in the solution and squeezed or centrifuged to remove excess solution. Yarn may be passed continuously through the solution or it may be dipped in skein form in the solution and then squeezed or centrifuged to remove ex cess solution. Flat fabrics may be passed through the solution orthe solution. may be applied from rolls or by'spraying and the excess may be removed by squeezing between rolls, passing betweenwiper or doctor blades, or the like, or by vacuum. extracting- Articles, as of clothing, may be dipped in the solution or sprayed. Fabrics or. articles of clothing may be treated locally by spraying.
Resin forming compound solutions of the present invention are stable under ordinary conditions up to 5% for periods. of one week or more: It. should be pointed out, however, that solutions to which a catalyst, has been added, for examplethecatalyst prior to application of the resinformingsolution. In this case, however, care must not one be taken that the catalyst chosen is which. will injure the particular textile material to be treated. It should be further pointed out thatv attempts to neutralize the catalyst in the resin forming solution will yield an unreactive resin, i. e. one which will not react with the cel lulose to. be impregnated.
In addition. to the resin forming compound having the above. general formula, the. sulfones when used alone are useful for treating textile materials to stabilize the same against repeated Divinyl sulfone is particularly useful in thisrespect. The procedure is essentially the same-as that herein.- before outlined. However, due to the lachrymatory and. vesicant properties. of divinyl sulfone; j necessary precautionary measures mustrbe taken when using the same, in order to protect; the workers against poisoning. Therefore, while the sulfones alone produce the desired results, it is preferred to employ the above-named resinformgreatly reduced or negligible lachrymatoryproperties.
As illustrative of the present invention, the given but itshould be thereby;
EXAMPLE; I
The resin forming compound in thi case was prepared? by reacting 2 mole of divinyl sulfone with one mol of urea. by adding the former very slowly to a 25% argueous solution of urea containing 0.38% by weight of sodium hydroxide. Thereaction temperature was maintained at'20 C; The resultant resin forming compound solution was then diluted in 3 parts to yield 3, 5, and 7% solutions. Into each of these solutions was immersed 300 denier/80 filament regular bright viscose rayon yarn in the form of skeins for a period of approximately 30 seconds, the solutions being maintained at room temperature. The skeins of yarn were removed from the solutions and the excess solution removed by centrifuging.
Thus by treating the rayon with the resin the water retention of the yarn is greatly decreased without affecting the tensile strength to any appreciable extent.
EXAMPLE II In this case divinyl sulfone was added to a 50% aqueous solution of urea, in equimolar proportions. After addition wa complete, the solution was refluxed for one hour under 760 mm. pressure. i The solution was then allowed to cool and divided into 4 portions, two of which were diluted to contain 5% resin and two to contain resin. Each of the four solutions was catalyzed by the addition of 0.25% sodium hydroxide. 300 denier/80 filament regular bright viscose rayon yarn, in the form of skeins, was immersed in each of the solutions for a period of approximately 30 seconds, the solutions being maintained at room temperature. Upon removal of the yarn the excess solution was removed by passing the yarn through squeeze rolls. The yarn that had been treated with a 5% solution and a 10% solution was dried at 100 C. and yarn treated with 5 and 10% resin solutions was dried at 100 C. and then cured at 150 C. for approximately 30 minutes. The treated yarn was tested with the following results:
Table No. II
Tensile (gins/denier) Percent Percent Elongation W'ater Retention Percent s Resm Proce 5 Dry Wet Wet 10. I Dry@ 100 10 Cure 150 C.
Again the water retention was greatly reduced with no appreciable effect on tensile strength. An increase in concentration of resin plus curing -of the same after impregnation gave the best results.
Similar tests to the above were run using isopropenyl sulfone and propenyl sulfone. In all cases the results were comparable with those given in Tables I and II. There was an appreciable reduction of the percentage water retention without hindering the tensile strength.
EXAMPLE III The procedure outlined in the above examples was essentially followed in impregnating crimped on a stainless steel spool with the same tension on the treated tow.
' A 10 inch length of tow from both the treated and control was mounted between two clamps with a very low tension. The tow waswetted and then loaded with a 25 gram weight. The tow was then permitted to dry at the extended-length and then finally released from the clamps, rewetted and dryed while in a relaxed state. Individual filaments were removed from the treated and untreated tow at various steps to observe change in crimp. The treated filaments remained as well crimped as the unstretched filaments while the untreated filaments had practically no crimp left at all. This is believed to be due inpart to the reaction which takes place between the cell'ulos and divinyl sulfone. v
The concentration of the divinyl sulfone may be varied between 2 and 10 The treatment with divinyl sulfone and the like may take place on the filaments, fibers, or the fiber or filament tow, or the material may be treated after being spun into a yarn or woven or knit into a fabric. The same isftrue when employing the resin forming compounds, such as the reaction product of urea and divinyl sulfone.
By means of the present invention, it is possible to produce textile articles which have a greater drying rate due to the fact the yarn, from which the article is made, will take up or retain less water after washing. There will be less swelling of the yarn thus alleviating a great deal of the distortion in fabricated articles after washing. The cellulose reacts with the resin hence the latter is not removed from the textile material upon repeated washing. Crimped fibers or filaments, yarns, fabrics, etc., when treated in accordance with the present invention; have their crimp set. Numerous other advantages will be obvious to those skilled in the art.
It is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined in the appended claims.
