17' Claims. (Cl. ,2528.7)

The present invention; relates to of matter. Morespecificaily itrelatesto a novel textile treating composition.

It is an object of the present invention to provide an oil base, anti-static finish for textiles.

It is. another object of the present invention to provide a textile treating composition for; containing. an oil active agent.

It is a further object of vide textiles which are rendered anti-statics by application thereto of an oil containing a cationic surface active agent, solubilized therein.

These and other objects will become apparent in the course of the following specification and claims.

be of the conventional petroleum base, lubricating grade. Their viscosities may vary through wide ranges epending upon the anticipated application. A particularly suitable oil for textile treatment is refined mineral oil having a viscosity of 50 Saybolt Universal seconds at 100 F. Such oils are available commercially from major oil companies and textile supply houses and are sol under such trade-marks as Sunvis 11, Topaz A and Absorbent K. Other oils of animal and vegetable origin may also be used for specialized applications.

The components are combined by melting the organic 'morpholinium compound and the solubilizer together. After solution is obtained, Frequently, it is advisable to warm the mineral oil slightly (to about 60 C.) prior to its addition. A few drops of water may be added to obtain a clear solution if the composition appears cloudy.

The proportion of components may vary widely depending on the nature of the textile and the particular operation for which it is being prepared. In general, the oil component may comprise from 70 to 90% of the final composition. The organic morpholinium derivative has been found effective at concentrations as low as 3%. However, 10% or more may be solubilized and suitably applied. The solubilizing component composes 7 to 20% of the finished composition and must be at least equal by weight to the amount of organic morpholinium derivative employed. Where a combination of polyoxyethylene derivatives and partial esters of long chain fatty acids with polyols is employed, the ratio of these components may vary The following examp invention.

These lubricating antistatic compositions may be apthe textile by the same means and with the same conventionally employed for oil application. To minimize electrostatic tendencies to a workable extent, it has been found desirable in extreme cases of which nylon is an example to deposit enough finish to comprise about 2% to 3% by weight of finish based on final treated textile. Where the static problem is not so acute, such as in the case of viscose rayon, as little as 'l% is effective. After the finishing composition has been applied and air dried it may be evaluated for electrostatic properties by rubbing twelve times with a glass rod to induce a charge and then, after observation and grounding, rubbing twelve times with a hard rubber rod to induce an opposite charge. Observations are given electrostatic ratings as indicated in Table II.

The compositions are widely useful for the purpose described above for textiles of synthetic or natural origin. It may be applied to fibers, staple fibers, felts, cords, threads, yarns, pellicles, filaments, fabrics and the like to textiles of animal, vegetable, mineral and synthetic origin. Among such substances may be mentioned cellulose acetate, regenerated cellulose, acrylic polymers and copolymers, vinyl polymers and copolymers, mixed copolymerization products of dibasic acids such as those of adipic acid and hexamethyldiamine, vinylidene, chloride polymers, the synthetic proteins, cotton, wool, glass, linen, asbestos and the like. The composition is also useful in the treating of hair.

It will be apparent to those skilled in the art that many variations are possible without departing from the scope of the invention.
