Process for improving the spinning inaccuracies natural and synthetic textile fibers

In the practice of spinning - in the following the production of worsted and mapped yarns from different types of natural as well as synthetic textile fibers - upick oils or fats are applied to the fibers before spinning in order to increase the lubricity of the fiber and that To make it easier to spin them «Spinning oils are, for example, oleic acid and mineral oil, etc., which are emulsified in a barrel with the aid of an emulsifying agent and then applied to the laser in JPorui of the emulsions, tu» is already known, for the same purpose a solution or dispersion einθβ Alkylenoxyd-Additlonsprodukte a to add.

The spinning of synthetic Feηerr, z.fi, alone or with the addition of frolle or cotton, has the requirements to the dpicköle increased. The increased openness speeds also place higher demands on them the SpioktJle. So the Jpieköl should be able to To prevent static electricity build-up or dem to counteract what would otherwise make spinning the Funer difficult or even impossible. forward the oplck oil should preferably be used to enhance the iarn or cloth to give a softer feel. Idea is particularly true in cases where the Pick oil is not removed from the end product by subsequent washing.

It has now been found that sulphonated products yield: Ukylene oxide addition products Can be used as Jpioköle in the spinning of textile fibers. should be addition products of alkylene oxides such as ethylene oxide, iropylene oxide and / or

Butylene oxide denotes various hydrophobic substances that contain polar groups or bonds of an active hydrogen atom. By suitable selection of the hydrophobic part of the molecule and the chain length of the alkylene oxide, nan can alter the properties of the product depending on the technology. For example, the ethylene oxide chain can be linked to the hydrophobic group by an ester, ether, amide or amine bond the polar group is formed by the groups -COOH or -MU or -COIHg, a compound can be obtained by adding 3-10 mol of ethylene oxide and sulfonating the resulting addition product which has softening properties of the textile fiber. Pail »an alkylaryl group such as 2.B. If an alkylenephenol with 8-12 carbon atoms in the alkyl chain is used as the hydrophobic part of the molecule, one can obtain a compound with a suitable length of the alkylene oxide chain, for example a chain length corresponding to 2-6 alkylene oxide units, and sulfonation of this addition product very effectively counteracts the build-up of static chargesWith a suitable selection of the hydrophobic component and with a suitable ratio between the hydrophobic and the hydrophilic molecule, products are obtained that have properties that increase the environment _9, whereby a greatly improved adhesion of the fibers to one another is achieved . Such properties are of course not restricted to certain zinc compounds, but rather certain sulfonated alkylene oxide addition products can have good white-resistant properties as well as good antistatic properties. Another advantage of the products proposed according to the present invention is the fact that

that al "with a suitable chain length easily diapered into aaeaer can be easily or easily • You can easily remove the fibers by washing them afterwards can be removed

Examples of suitable hydrophobic substances of the invention are used to prepare the sulfonated alkylene oxide-Addltioneprodukte geaäB H5nnen include: carboxylic acids, such Pelargoneäure, C & pronsäurs, Laurineäure, myristic acid, Ialeitineäure, stearic acid, Beheneäure, Arachlnsäure, oleic acid "llnolsäare _v linolenic acid and abietic acid; Alcohols such as, for example, octyl, monyl, lauryl, trideoyl, fetradeoyl, cetyl, octadecyl, glycosyl, oleyl and abietyl alcohol; Asides such as κ · Β · cetyl, decyl, fetradeoyl, oetadeoyl, oetadeeenyl «octadeeadienylaid amines such as cetyl, deeyl, tetrmdecyl, octadecenyl, octadecenyl, octadeeadienyl such as Ihecols. Octyl, nonyl, leoyl, undlecyl and dodecyl phenol. The hydrophobic alkyl chains can be straight or branched.

In certain cases it can be beneficial «the sulfonated Alkylene oxide additive products mixed in other substances. So it is possible to Mixtures of sulfonated ethylene oxide additive products and non-sulfonated alkylene oxide additives Use cu in those cases where friction increases The properties of the Spiokoils are particularly desirable are among such non-sulfonated alkylene oxide additive products can be mentioned ι alkylphenols · alkylene oxide additive products, esters of resin acids such as t.B. Abietic acid with iolyglycols, etc. Also know to increase the quality of the 4-pack 3-jick oils the sulfonated alkylene oxide addition products old other sulfonated products are mixed, e.g. Fatty alcohol sulfonates or sulfonated iflane owls.

The amount of opicköl used, like the concentration of the opicköl in Vtaseer, depends on the properties of the material being spun. Pure kaon yarns are generally 0.1-0.5 * ipickiil, enough to lie about the weight of the yarn *. In the production of carded yarns on the outside, on the other hand, normally 0 _f 3 - 2.0 # üpiököl, depending on the weight of the yarn, are used.
