Definitions

• This invention relates to the treatment of yarn and other textile materials and relates more particularly to the conditioning of yarn made of organic derivatives of cellulose whereby'the same may be more successfully subjected to knitting or other textile operations.
• An object of our invention is to'treat yarns containing organic derivatives of cellulose with a conditioning fluid whereby the same are rendered more pliable and therefore more suited' for use in textile operations, such as knitting,
• a further object of our invention is to treat yarns or other textile materials containing organic derivatives of cellulose with a conditioning fluid containing a substance that is a solvent or is at least a latent solvent for the organic derivative of cellulose contained in such yarns.
• yarns or other textile materials containing organic derivatives of cellulose are treated, before being subjected to a fabric-forming textile operation, with a conditioning fluid comprising at least a latent solvent for the organic derivatives of cellulose contained in such yarn or materials, i. e.,.a latent solvent or a solvent for said organic derivatives of cellulose.
• the textile materials to be treated in accordance with our invention may be in the form of yarns containing a plurality of filaments made of cellulose acetate or other organic derivative of cellulose.
• the textile materials may be in the form of artificial bristles or straw containing such cellulose acetate so as to make it possible to knot, bend or braid them more easily.
• such textile materials may contain other organic derivatives of cellulose such as cellulose formate, cellulose propionate, cellulose butyrate, ethyl cellulose, methyl cellulose and benzyl cellulose.
• the yarn to be treated need not consist wholly of yarns of cellulose acetate but may also contain fibres of other materials such as natural silk, artificial fibres of reconstituted cellulose, wool, cotton, etc.
• the yarns of cellulose acetate maybe formed from continuous filaments or the same may be spun from short staples or short lengths of such filaments.
• solvents or latent solvents may be used, preferably those that are relatively non-volatile, i. e. having a boiling point above 120 C. and that are soluble, in or readily removable by water.
• relatively non-volatile solvents or latent solvents for cellulose acetate that are more or less soluble in water are benzyl alcohol, diacetone alcohol, monoacetin, diacetin, acetol (acetyl carbinol),
• cyclohexanone cyclopentanone
• ethyl lactate di-" methyl tartrate.
• relatively non-volatile solvents or latent'solvents for cellulose acetate not soluble in water such as tri-' Y phenyl phosphate, 2. mixture of triphenyl phosphate and tricresyl phosphate, or triacetin may be employed.
• the conditioning fluid applied to the yarn may consist wholly of one or a mixture of two or more of the solvents or latent solvents, generally it is preferable to dilute the same with a liquid that dissolves such solvent or latent solvent but which has no solvent action on the cellulose acetate or other organic derivative of cellulose of the yarn.
• diluents are water and preferably a relatively non-volatile liquid miscible with water such as ethylene glycol, diethylene glycol, propylene glycol, ethers of glycols, such as the mono ethyl ether of ethylene glycol, etc.
• the amount of diluent present is such that the concentration of the solvent or latent solvent for the cellulose acetate is from 2% to 30% or more of the conditioning fluid.
• concentration of the conditioning fluid with respect to the solvent or latent solvent may be more than 30% and up to 100%., provided it is not applied in such amounts .and such concentrations as to dissolve the fllaments of the yarns or to cause them to stiffen or coalesce together.
• conditioning agent applied to the yarn this also may be varied, and we have found that, for instance in the case of a, conditioning agent containing ethyl oxy butyrate in amounts of 2 to 5% of the weight of the conditioning agent, if quantities of such condiing the yarn over pads or wicks that are impregnated with the conditioning fluid or by passing over rollers, the bottoms of which are immersed in the conditioning fluid.
• the conditioning fluid may be dripped onto the yarns while they are in transit, and alsothe yarns may be caused to dip into a bath containing the conditioning fluid while they are in transit prior to being wound onto a suitable package.
• the conditioning fluid may be applied as a spray onto cones, bobbins, pirnsor other packages while the same are being wound, so that the spray is being continuously applied during the formation of the package.
• the yarn may be treatedat the spinning cabinet with .the conditioning agent while it is being transmitted from the spinning cabinet in which it is spun from solutions of organic derivatives of cellulose and prior to being wound and/ or wound and twisted into yarn.
• the yarn treated in accordance with this invention is very-pliable and flexible, and may be knitted, woven or subjected to any other suitable textile operations, to form knitted or woven fabric,"hosiery, or other articles.
• the solvent or latent solvent be completely removed from the fabric by scouring or during dyeing or any other finishing operation.
• the solvent or latent solvent tends to lower the melting point or safe ironing point of the material when it is present, but after it is removed by any suitable means, the resulting textile material has as high a melting point and safe ironing point as the untreated textile material.
• Cellulose acetate yarn treatedin accordance with this invention has many important advantages. As stated they are very pliable and flexible, and even after storage'for a prolonged period of time, retain this pliability and flexibility.
• This yarn may be knitted on circular knitting machines or onwarp knitting machines to produce fabric of many wales and courses per unit length, which fabrics are substantially free of pin holes, distortions, tension lines, etc. and have a much better apprearance than fabric made from untreated yarns. when treated by this invention. may be knitted on certain circular knitting machines which are,
