Description
The Related Art
A known method of improving the smoothness of textile fiber material is that of so-called dry-paraffining in which the yarn to be treated is guided over solid paraffin during the spooling operation. A quantity of paraffin, depending upon the type of paraffin, the contact pressure, and the speed of the material, is absorbed by the thread through abrading.
However, this method has substantial disadvantages. Thus, it is necessary to apply an accurately defined quantity of paraffin for the purpose of frictionless further processing of the textile material, different types of paraffin being used depending upon the time of the year. During spooling, it is necessary to reduce the normal spooling speed by 20 to 25%. Furthermore, the paraffined spools have to be stored at suitable temperatures.
During the paraffining operation, sliding of the individual strands of the yarn occur and the threads might break during processing of the yarn, particularly in the case of single ply yarns. A further disadvantage is the possible efflorescence of the paraffin during subsequent steaming and ironing processes.
Furthermore, the dry-praffining operation is generally inadequate to impart a satisfactory feel to the material. This requires additional treatment with a conventional cationic brightener or scrooping agent.
Objects of the Invention
An object of the present invention is to develop an auxiliary agent which is suitable for treating the various textile fiber materials, such as cellulose fibers, wool fibers and synthetic fibers, or mixtures thereof, and which imparts to these materials the smoothness required for further processing and a satisfactory feel and antistatic effect.

(II) from 15 to 35% by weight of paraffin having a melting range of from 40.degree. C. to 60.degree. C., where the total of components (I) and (II) is from 20 to 50% by weight,
(III) from 1 to 10% by weight of at least one fatty acid amidopolyamine having the formula ##STR1## wherein --OCR.sub.1 is the acyl of a fatty acid having from 14 to 22 carbon atoms, m is an integer from 2 to 6, and n and o are numbers from 1 to 3,

These smoothing agents constitute storage-stable aqueous dispersions whose specific substantivity especially enables the smoothing agents to be applied to fibers by the bath exhaustion method.
Suitable fatty acid esters of component (I) are fatty acid esters from 1 mol of a fatty acid having from 14 to 18 carbon atoms and 1 mol of an alcohol selected from the group consisting of alkanols having from 1 to 8 carbon atoms and alkanepolyols having from 2 to 8 carbon atoms, in particular, methyl palmitate or methyl stearate, and the corresponding ethyl esters.

However, it is also possible to use partial esters of ethyleneglycol, propyleneglycol, glycerine, pentaerythrite or sorbitol, such as palmitic acid monoglyceride or stearic acid monoglyceride.
The paraffins (II) used are preferably those having a melting range of from 50.degree. C. to 60.degree. C.
The fatty acid amidopolyamides of component (III) are obtained preferably from saturated fatty acids or mixtures of fatty acids having 16 to 22 carbon atoms with polyalkylene polyyamines having the formula ##STR7## wherein m and n have the above-assigned values, such as diethylene triamine, dipropylene triamine, triethylene tetraamine, tripropylene tetraamine, tetraethylene pentamine and tetrapropylene pentamine. The reaction is effected in a molar ratio such that at least one amino nitrogen atom, capable of salt formation, remains. The product of reaction from 2 mols of stearic acid with 1 mol of diethylenetriamine may be mentioned by way of example. The fatty acid amidopolyamines in the smoothing agent composition of the invention are present in the form of salts thereof with lower carboxylic acids or hydroxycarboxylic acids having 1 to 4 carbon atoms, such as acetic acid or glycolic acid, presented as component (IX).

The following are representative quaternary ammonium compounds: Lauryltrimethyl ammonium chloride, dodecylbenzyltrimethyl ammonium methosulfate or distearyl-dimethyl-ammonium chloride.
The smoothing agent compositions also can contain from 0 to 5% by weight, preferably 0.1 to 0.5%, by weight of an ethylene oxide adduct to a compound having a replaceable hydrogen and at least 9 carbon atoms, such as straight or branched chain, saturated or unsaturated higher alcohols having 9 to 22, preferably 16 to 18, carbon atoms, particularly alkanols and alkenols, such as the adduct of 20 mols of ethylene oxide to 1 mol of oleyl alcohol or to alkylphenols having 12 to 20 carbon atoms, such as the adduct of 10 mols of ethylene oxide to nonylphenol or to higher fatty acids having 12 to 22 carbon atoms, such as the adduct of 15 mols of ethylene oxide to tallow fatty acids, or to fatty acid amidopolyamines or alkylamines having 12 to 22 carbon atoms, or mixtures of these adducts. The ethylene oxide content of the adducts should be 35 to 85% by weight. The ethylene oxide adducts to higher fatty alcohols and alkylphenols are preferred, as component (VI).
The protective colloids of component (VII) are preferably cellulose ethers, such as methylcellulose or hydroxyethylcellulose, glue, polyvinyl alcohol or gum arabic.
Suitable solvents of component (VIII) which are immiscible in water are the aliphatic or aromatic hydrocarbons having 5 to 10 carbon atoms, such as hexane, benzene, toluene, xylene, alkylbenzene; symmetric or asymmetric ketones, particularly lower alkanones, such as diisobutylketone, symmetric or asymmetric ethers, particularly lower alkyl ethers, such as dibutyl ether, or halogenated hydrocarbons, such as trichloroethylene or perchloroethylene.
The lower carboxylic acids of component (IX) serve to form salts with the fatty acid amidopolyamines or to neutralize other basic constituents of the composition and, advantageously, should be used in a quantity of from 3 to 6 mols per amino nitrogen equivalent. Preferably these acids are alkanoic acids having from 1 to 4 carbon atoms and hydroxyalkanoic acids having from 2 to 4 carbon atoms. By way of example, acetic acid or glycolic acid are suitable.
The composition is made up to 100% by weight with water (X) and is converted into a stable dispersion. This can be effected in a conventional manner by agitation, at elevated temperatures, if required, with the use of agitators, dispersers, homogenizers, etc. Preferably, distilled or demineralized water is used.
The smoothing agents, claimed in accordance with the invention, can be used for the finishing of textile fiber materials, such as wool, cotton, rayon, polyacrylonitrile fiber, polyester fiber, polyamide fiber, triacetate fiber, polyethylene fiber, or polypropylene fiber materials and mixtures thereof, preferably mixtures of polyacrylonitrile/wool, polyacrylonitrile/cotton, polyester/wool, polyester/rayon and polyamide/wood, and mixtures of mineral fiber material, such as asbestos or glass fibers, preferably glass fiber material. Preferably, the fiber materials are present in the form of cross-wound bobbins, rocket bobbins, hank yarn, muffs or combed sliver or slubbing.
The material may be bleached, dyed and/or finished so as to be shrink free.
The smoothing agents can be applied in conventional apparatus, such as dyeing apparatus for cross-wound bobbins, rocket bobbins, hank yarn, muffs or on the backwashing machine for combed sliver. Advantageously, work is carried out by the bath exhaust process from an aqueous liquor with a goods/liquor ratio of 1:8 to 1:40 and a liquor pH of 2 to 8, preferably 4.5 to 6.5, in an HT apparatus, or 6.5 to 7.5 in open apparatus, at a temperature between 25.degree. C. and 80.degree. C., the concentration being 0.2 to 3.0%, preferably 0.2 to 1.5%, by weight of smoothing agent, based on the active smoothing agent substances relative to the weight of the goods.
Finishing can also be effected in the presence of electrolytes, such as sodium acetate, sodium sulfate, sodium chloride, etc.
The finished material has excellent smoothness, and a soft, voluminous and supple feel, so that there is no need for an additional application of scrooping agents. The smoothness values or friction values, measured on the friction value balance manufactured by the firm Schlafhorst, are below 0.18 My in all the textile fiber materials, preferably 0.12 to 0.15 My, and have a high degree of uniformity. This results in very satisfactory workability when, for example, knitting or weaving. Furthermore, no difficulties are caused by electrostatic charging when further processing the finished textile fiber materials. The knitted and woven articles made from yarns of this type exhibit satisfactory and smooth stitches.
The present invention will now be further described by means of the following examples of smoothing agents made in accordance with the present invention and their uses. These examples are not to be deemed limitative of the invention in any respect.

Examples 1 to 9 are examples of various smoothing agent compositions of the invention.
Example 1
The ingredients were mixed and dispersed to form a stable, aqueous dispersion.
Example 2
Example 3
Example 4
Example 5
Example 6
Example 7
Example 8
Example 9
The smoothing agents of Examples 1 to 9 are stable dispersions which are miscible with water in any ratio.
The following are examples of the use of the smoothing agents of the invention.
Example 10
Highly swollen polyacrylonitrile yarn, which had previously been dyed in a conventional manner with cationic combinations of dyes and which had been cold-rinsed to 50.degree. C., was treated for 15 minutes in a hank dyeing apparatus in a liquor ratio of 1:25 with a liquor which had been adjusted to a pH value of 7 to 7.5 and which contained 1.5% of the smoothing agent of Example 1, based on the weight of the goods. During this period of time, all the smoothing agent was exhausted and attached to the fibrous material. The material was subsequently centrifuged and dried.
The yarn finished in this manner had very satisfactory smoothness (friction value = 0.15 My), a soft feel and could be knitted without any after-treatment.
The knitted article was distinguished by very uniform stitches.
Example 11
After having been dyed, a mixed yarn comprising polyacrylonitrile and wool was treated for 20 minutes with 2.0%, based on the weight of the goods, of the smoothing agent of Example 2 in a fresh bath with a liquor ratio of 1:10, and at a pH value of 5.0 in a cross-wound bobbin HT dyeing apparatus with increasing temperature (to 45/50.degree. C.) and was then centrifuged and dried.
The material exhibited excellent smoothness (friction value 0.14 My) and could be readily further processed. The knitted article made from the material had a voluminous feel without any additional brightening treatment and was free from nebs.
Example 12
Wool yarn 32/2 on a rocket bobbin, felt-free finished and reactively dyed, was treated for 20 minutes at 40.degree. C. with a liquor containing 2%, based on the weight of the goods, of the smoothing agent of Example 3 in the liquor ratio of 1:12 and a liquor pH value of 6.0, and was then centrifuged and dried.
The material finished in this manner showed a very uniform deposit of the smoothing agent and could be further processed in a trouble-free manner to provide a high-quality knitted article.
Example 13
After thorough deacidification, a cotton material dyed with indanthrene (R) was treated for 10 minutes at 45.degree. C. in an open dyeing apparatus with a liquor (liquor pH value 5.5) containing 1.5% of the smoothing agent of Example 4 (based on the weight of the goods). The smoothing agent was extensively attached to the fibrous material with excellent uniformity.
The material was centrifuged, dried, and wound onto "9.degree. 15' bobbins".
The drying operation was carried out in a rapid drier at 120.degree. C., and the smoothing agent did not evaporate.
Example 14
Hand-knitting yarn comprising 80% polyacrylonitrile and 20% wool (mohair) was treated for 20 minutes at 45.degree. C. in a hank yarn dyeing apparatus with a liquor containing 1.5%, based on the weight of the goods, of the smoothing agent of Example 1 with the liquor ratio 1:30 and a pH value of 7.0 and was then centrifuged and dried.
The resultant material exhibited excellent smoothness (friction value = 0.16 My) and could be wound into a ball without trouble caused by electrostatic charges.
The preceding specific embodiments are illustrative of the practice of the invention. It is to be understood, however, that other expedients known to those skilled in the art or disclosed herein, may be employed without departing from the spirit of the invention or the scope of the appended claims.
