The invention relates to textile manufacturing, and in particular to compositions for the treatment of textile yarns from fibers by oiling while preparing them to re the fuck knitwear production.

From patent and scientific and technical sources known to many chemicals used to process the oiling of various fibrous materials and textile yarn.

So famous, in particular, the sizing for processing fibrous materials containing wt. %: mineral oil 64-70, emulsifier 24-30, monooleate glycerol 1.5 to 5, the drug Sintana 0,2-2 (Sizing for processing fibrous materials. A. C. the USSR 471407 D 06 M 13/02 bull. 19 from 25.05.1975). The sizing is designed to improve the processing ability of textile threads in reducing the coefficient of friction, reducing breakage of filaments and their electrified. However, the processing of fibrous materials this sizing has several disadvantages, in particular the adhesion of the fibers and their complexes; insufficient to ensure the quality of the technological process of reducing the coefficient of friction of the threads about nitroprusside parts of textile machines. In addition, the sizing is irritant effect on the skin of a person that does not meet the necessary sanitary-hygienic requirements.

Also known lubricant for synthetic fibers, containing in wt. hours : mineral is metilirovannah ALKYLPHENOLS (or drug Sintana DC-4 on the basis of ethoxylated alcohols WITH10-C16) 4-8 and water 2-5 (Lubricant for synthetic fibers. A. C. the USSR 812863, class D 06 M 13/02 1981 ). The sizing is recommended to reduce the electrified and improve the quality of winding synthetic threads. However, the sizing is not effective, mainly because of its high viscosity. The disadvantage of this composition is also uneven friction coefficient along the length of the processed threads, which leads to lower quality of the produced final product, in particular the increase in the number of breaks per unit weight of the knitted fabric.

Of the other compounds described in the technical literature, you can specify, for example, a sizing composition for processing complex khlopkopryadilnaya yarn, containing in wt. %: grease mineral oil or synthetic lubricant 10-30, antistatic (sulfate or phosphate) 10-25, emulsifier 20-35 and water 30-45 (Wen Yean Wu and Jiunn-yih Lee "Effect of oil on the Spread Width of the Composite Yarn". Textile Research Journol 6,1995, s. s. 343-347). This sizing composition improves the processing capability of a complex khlopkopryadilnaya yarn. But as the previous structures, it does not provide the necessary reduction of the coefficient of trenline.

The closest in technical essence and the achieved result of the claimed invention is a lubricant for synthetic fibers (known in the industry under the name N-02) containing vaseline oil, alkylphosphate (drug exits And or exits) and monooleate glycerin. Description this sizing is given, for example, in the technical specifications 6-14-51-76 (all-Union scientific research Institute of synthetic fibers, Kalinin, 1976 ). Such structure reduces the electrified coefficient of friction of the treated synthetic fibres and thus improves their ability to subsequent textile processing. However, as in the case of the treatment of textile yarns previously described counterparts, the film formed on the surfaces participating in frictional contact bodies, not strong enough and has a structure that does not protect nakonratchasima the metal parts of textile machines from harmful oxide films and therefore wears out quickly. All this predetermines the possibility of plastic deformation of the surface and deeper layers of textile yarns and nakonratchasima parts of textile machines, which in turn leads to Umea textile threads.

The technical problem solved by the invention, is to improve the processing ability of chemical textile yarn. In particular, the new structure allows to reduce the number of breaks per unit weight of the knitted fabric by reducing the coefficient of friction of the threads on notcontentindexed metal parts, knitting machines, as well as by reducing the electrified filaments and increase their strength.

This task is solved in that the composition for the treatment of textile yarns from fibers by oiling with mineral oil, alkylphosphate and monooleate glycerin, further includes an oxide of one of the transition metals, which is the oxidizing agent relative to the metal nakonratchasima parts of textile machinery and high unsaturated carboxylic acid in the following ratio, wt. %.

Mineral oil - 75,0-79,5

Alkylphosphate - 14-16

Monooleate glycerol - 5-6

The transition metal oxide is 0.5 - 1

Higher unsaturated carboxylic acid - 1-2

Introduction to the proposed composition for the treatment of textile yarns from fibers by oiling oxide of one yousee parts of textile machinery and high unsaturated carboxylic acid in the following ratio of components, wt. %:

Mineral oil - 75,0-79,5

Alkylphosphate - 14-16

Monooleate glycerol - 5-6

The transition metal oxide is 0.5 - 1

Higher unsaturated carboxylic acid - 1-2

ensure that the protective film formed by this composition on the textile threads, ORGANOMETALLIC salts, and in some cases ORGANOMETALLIC complex compounds. When the frictional interaction processed by the claimed composition of the textile yarn of man-made fibres metal nakonratchasima surfaces of textile machines ORGANOMETALLIC compounds, studies show, are partially dissociated state. Broken ORGANOMETALLIC compounds deliver metal ions, which are due to the redox reaction are discharged on the surface nakonratchasima parts of textile machines and form a uniform film. Usually metal parts of textile machines made of iron alloys. Therefore, as a transition metal, which is the oxidizing agent to iron, the composition may contain metals such as Cd, Co, Ni, Pb, Cu, Ag.

Educated proposed composition of the metal film has OC the VA, consequently, the upper part has no oxides and thereby eliminates a number of negative factors that increase the friction, increase wear and reduce strength, such as plastic deformation of the surface layers, surface roughness and absorption of parts and components. When the local wear of the formed film is its constant self-healing due to the flow on the exposed parts of the metal surfaces of the above-mentioned reactions. Thus on the whole surface area of frictional contact during movement of the treated textile yarn is formed self-healing metal film.

It should also be noted that the introduction of the higher unsaturated carboxylic acids gives the opportunity to form due to the double bond and the carboxyl group of the oligomeric structure included in the sphere of transition metals, and to be adsorbed on the surfaces of friction, procrea their surface layers. Studies have shown that it is this property increases the strength treated by the claimed composition of textile threads.

As the transition metal composition which contains monovalent copper. Copper has a standard electrode the mu is a necessary condition for carrying out oxidation-reduction reactions:

Eoabout(copper)-Eoin(iron) +0,1

where copper - oxidant and iron - reducing agent.

In addition, studies have shown that monovalent copper - active complexing agents and the interaction with higher unsaturated carboxylic acids forming organic salts of copper, as well as complex compounds of copper due to the interaction of copper ions with a carboxyl group-COOH via the main valence and group-CH= CH - by secondary valence.

Introduction in the inventive composition as higher unsaturated carboxylic acid, oleic acid leads to the formation of compounds that possess the properties required for the education on the friction surfaces of the protective film with the above properties and a stable dispersed emulsion in mineral oil.

In addition, the effectiveness of the presence in the composition of surface-active substances of other types, such as alkylphosphate and monooleate glycerin reflected in the increasing concentration and stability of the resulting compounds due to the additional interaction between uglevodorodnye radicals of these compounds and these surface-active substances.


Mineral oil - 77,6

Alkylphosphate - 15

Monooleate glycerin - 5

The monovalent oxide copper - 0,8

Oleic acid - 1,6

The possibility of carrying out the invention is illustrated by the following examples of the preparation of the proposed structure with various components, as well as comparative data given in table. 1-4. In these tables presents obtained on the basis of a comparative experimental studies of indicators of physico-mechanical properties and processing capacity of viscose, acetate, polyester and polyamide filaments as not processed, or processed by several variants of the preparation of the proposed structure and its closest analogue.

The composition is stirred for 30 min at t= 60oC. In a container heated to t= 75oC oleic acid brand And in the amount of 1.6 wt. % add the oxide monovalent copper in the amount of 0.8 wt. % and stirred for 5 min at t= 75oC. Connect the two is further heated. Composition for the treatment of textile yarns from fibers by oiling cooled to t= 20-25oC and poured into the feed tub warping machine, where it is applied on a textile yarn.

Example 2

In a container heated to 60oWith mineral oil of mark T (vaseline) and 77.6 wt. % add a mixture of the drug exits In the amount of 15 wt. % and monooleate glycerin in an amount of 5 wt. %. The composition is stirred for 30 min at t= 65oC. In a container heated to t= 75oC linoleic acid number of 1.6 wt. % add lead oxide PbO2at 0.8 wt. % and stirred for 5 min at t= 75oC. Connect these two songs and continue to stir for another 30 min to complete hamonization composition without further heating. Composition for the treatment of textile yarns from fibers by oiling cooled to t= 20-25oC and then used as in example 1.

The inventive composition for the treatment of textile yarns from fibers by oiling provides, as noted above, the formation on the surface of textile threads of the oil film containing in addition to alkylphosphate and monooleate glycerin, metallurg consisting of a layer included in the composition of the metal, a layer of surface-active substances and a layer of mineral oil. Such a structure of the protective layer on the friction surfaces ensures that the solution of a technical problem.

The ability of viscose, acetate, polyester and polyamide filaments for processing after the processing of their proposed composition, conducting production tests were evaluated according to the number of yarn breaks per 1 kg of the knitted fabric during the knitting warp knitting machine, as well as the change of physico-mechanical properties such as strength, coefficient of variation in strength, the relative tensile strength, coefficient of friction of textile threads in steel, electrical resistivity.

Textile yarn before the tests were kept in normal conditions at t= 202oC and relative humidity of 652% for 24 hours of sampling threads were carried out in accordance with GOST 6611.0-73 (ST SEV 2462-80).

Monitoring chemical processing textile yarns for warp knitting machines knitting production to determine the number of breaks was carried out on 100 kg of each type of thread, and then determined the average number of yarn breaks per 1 kg of produced tricot linear density of 25 Tex, polyester yarns with a linear density of 5.5 Tex and nylon yarns with a linear density of 5 Tex-treated composition according to the invention, prepared according to example 1 (option 3) and example 2 (option 4) presented in the above tables (option 3). For comparison, test data of physico-mechanical properties of these types of textile fibres, not processed in any structure (option 1), and processed currently applied by the lubricant prepared in accordance with the applicable specifications 6-14-51-76 (option 2).

As can be seen from the table. 1-4, the proposed composition for the treatment of textile yarns (options 3, 4) is markedly superior to known lubricant (option 2) on all major indicators, first of all, the ability to give viscose, acetate, polyester and polyamide filaments of the required quality for processing. This increases the strength of viscose yarn 23.0%; acetate filaments by 13.0%; polyester staple fibres by 1.0%; polyamide filaments by 4.0%. The coefficient of variation in strength is reduced to: viscose yarn 11.0%; acetate filaments by 12.5%; polyester staple fibres by 1.0%; polyamide filaments by 2.0%. Relative tensile load increases for: vis what I have become reduced to: viscose yarn 21.5%; acetate filaments by 7.0%; polyester yarn 25.0%; polyamide filaments by 32.5%. Reduced electrical resistivity for all kinds of threads on average 70%. In connection with the improvement of the above parameters reduces the number of breaks per 1 kg of the knitted fabric during the knitting of viscose yarn 50% acetate filaments by 25.0%, polyester yarn, 20% for polyamide fibres 17.5%.

Composition for the treatment of textile yarns from fibers by oiling is an oily yellow liquid with a greenish tint. The kinematic viscosity of the composition according to the claimed invention is at t= 25oC 22,0-28,5 C. Stable for 1 hour steady enough with the formation of the layer of cream is not more than 3 mm and drops of oil on the surface. As shown by experimental studies, the shelf life of the emulsion is not less than 6 months. The average number of composition on the treated textile threads, and for other similar compounds, is 2.0 to 2.5% by weight of the filament. The composition is removed from textile yarn after processing, as usual, during the subsequent technological operations connected with finishing of knitted fabrics.
