PORATION OF DELAWARE TEXTILE MATERIALS AND METHOD OF PREPARING THE SAME .No Drawing.

This invention relates to the preparation or treatment of textile materials, such as yarns or filaments made of organic derivatives of cellulose, whereby the same are rendered more amenable to textile operations or haveother improved properties.

An object of our invention is to prepare or treat textile materials, particularly yarns or filaments containing cellulose acetate or other organic derivatives of cellulose, by the employment of oils or fatty acids in con unction with lecithin, whereby the yarns or filaments are rendered more pliable and can therefore be knitted, woven or knotted more readily. Further objects of our invention will appear from the following detailed description.

In many processes of conversion of textile yarns suc as twisting, winding, knitting or weaving, it is desirable to apply finishes. which soften or lubricate the arns. The

finishes considered most'useful or this purpose containoils, such as olive or castor oil. However when such oils are applied to the yarn, they tend to polymerize and form viscous and ummy bodies upon ageing. We have found that if lecithin is added to such oils, yarns to which the oil and lecithin have been applied, remain soft and not sticky when exposed to the air fOIIlOIlg periods of time.

" In accordance with our mvention, we employ the animal or vegetable oils or the fatty acids derived therefrom in conjunction with lecithin in the preparation or treatment of textile materials particularly those containing cellulose acetate or other organic derivatives of cellulose.

The animal or vegetable oils employed may be any suitable one such as olive oil, castor oil, cocoanut oil, Neatsfoot oil and ingeneral Application filed April 17, 1980. Serial No. 445,205.

the product in a form containing some of the oils with which it occurs naturally, since pure lecithin tends to oxidize rapidly. The amount of lecithin employed may be any suit able one say from 0.5 to 5% of the weight of the oils or fatty acids employed in the textile process. i

In one form of our invention, the vegetable or animal oils or the fatty acids in admixture with the lecithin may be added to the atmosphere as in dry spinning or into a precipitating bath as in wet spinning.

In another form of our invention the mixture of the oils orfatty acids and the lecithin may be applied to the yarns, filaments or fabrics after their formation. They may be applied either alone or in admixture with other materials as a lubricant or finish. Thus the lubricant or finish may also contain softening agents such as polyhydric alcohols, examples of which are glycol, diethylene glycol or I glycerine.

The textile materials to be prepared or treated in accordance with this invention preferably contain organic derivatives ofcellulose which may be organic esters of cellulose orcellulose ethers. Examples of such organic esters of cellulose are cellulose acetate, cellulose propionate, cellulose formateand cellulose butyrate, 'while ex- 'amples of cellulose ethers are ethyl cellulose, methyl cellulose and benzyl cellulose.

Yarns, artificial straw or filaments when prepared or treated in accordance with thls invention have great pliability due to-the presence of the animal or vegetable oils or the free fatty acids, as shown by the fact that such yarns may be readily knitted into a fabric containing many stitches per unit length, and artificial bristles, horsehair and straw may be knotted quiteatightly and bent as quite severely without breaking. Moreover when such yarns are exposed to the an for lon periods of time, because of the presence of t e lecithin, they retain their softness and pliability and can be readily knitted.

In order further to illustrate our invention, but without being limited thereto, the following specific example is given.

Ewample- A finish is prepared as follows:

Olive oil 99 parts by weight Lecithin The above mixture is applied to a yarn consisting wholly of acetone-soluble cellulose acetate filaments, by causing such yarn to pass 1 part by weight of cellulose acetate containing a glyceride of a fatty acid and lecithin. 9. Textile materials containing filaments of-cellulose acetate containing 011% oil and lecithin.

In testimony whereof, we have hereunto subscribed our names.

over wicks, rollers or other'furnishing device for applying such mixture, in their transit from the spinning machine in which they are formed to a winding device. The amount of finish applied is from 1 to 2% of the weight of the yarn.

The yarn so treated is quite pliable and knits well, takes high twists smoothly and generally exhibits improved properties.

- Moreover even after ageing in the presence of air or for a long period of time the yarn remains soft and free from stickiness.

Itv is to be understood that the foregoing" description is given merely by way of illustration and that many variations may be their glycerides in association with lecithin.

3. In a. process of preparing or treating textile materials containing cellulose acetate,the step of introducing olive oil in association with lecithin.

4. Process 'of improving the properties of filaments or yarns containing organic derivatives of cellulose comprising applying thereto a finish comprising a glyceride of a fatty acid and lecithin.

5. Process of improving the properties of textile materials containing cellulose ace-' tate comprising applying thereto a finish comprising a glyceride of a fatty acid and lecithin.

6. Process of improving the properties of filaments or yarns containing cellulose acetate comprising applying thereto a finish containing olive oil and lecithin.

8. Textile materials comprising filaments
