The invention relates to the field of protection bioorganica. Can be used in the textile industry, namely in the processing of wool fibres.

One of the stages of wool processing in the textile industry is a stage oiling, which is carried out using special fluids - oil, in order to improve the adhesion between the fibers and to obtain a more complete rovings. Oiling prevents the beam of the fiber from damage and facilitates the stretching of the fibers.

Ivanovo, 1996, - s-175) describes compositions of derivatives of the paraffins, synthetic fatty acids and new effective surface-active agents (surfactants)that act as emulsifiers and stabilizers of emulsions of oil. From (Schoenfeld N. Surfactants based on ethylene oxide. TRANS. with him./Edited by N. N. Lebedev. Ed. 2-E. - M.: Chemistry, 1982, - s) know the use of anionic surfactants in a mixture with neinogennye.

In (O. Kozlova, ilina, O., I. Odintsova//international scientific-technical conference "problems of development of low-waste and resource-saving environmentally friendly technologies in the textile and light industry" (Progress-95), Ivanovo, October 31 - November 3, 1995: abstracts. Dokl. Ivanovo, 1995, - s-137) describes the composition of oil-based paraffin, chlorinated paraffin wax, synthetic fatty acids. Emulsifiers and stabilizers of emulsions of oil surfactants are: neonols, phenoxy and aleax, fatty alcohol ethoxylates.

The common features of the above technical solutions proposed by the invention consist in the use of the composition of the oil of an oil base, anionic surfactants in a mixture with nonionic (ethoxylated fatty acids, esters of polyhydric alcohols and others) as emulsifiers and stabilizers of emulsions of oil.

Main is not the remnants of emulsions known sizing is their susceptibility to biological defeat during storage and application. The use of contaminated emulsion sizing leads to rotting wool, odors, reduce the strength of the thread and pick-up to a uniform colour. Bactericidal defeat subject to wool, processed fresh emulsion at the stage of aging before staining. These drawbacks are partially removed at the stage of washing wool fibers before dyeing, resulting in increased material and energy costs.

The closest (prototype) to the proposed sizing the technical essence and the achieved effect is "Sizing B-73 (TU 6-14-999-80), representing a composition comprising mineral oil and anionic and nonionic emulsifiers - oleic acid, sulfonated castor oil, triethanolamine, Aleax 5 Xylan (monooleate glycerol). Known sizing is characterized by the following physicochemical properties:

hydrogen ion exponent (pH) of 10% aqueous emulsion7,0-8,0
the stability of a 10% aqueous emulsion day.stable
during the day
mass fraction of moisture, %, max6,0
the viscosity (WU) at 20°s, not more than 16
mass fraction of fatty substances, %, not less than92,5

Working concentration (wt.%) the sizing of the emulsion during processing:

- of wool in hardware production to 20;

- wool mixtures in worsted manufacture up to 5.

The disadvantage of sizing is bioforest.

Object of the invention is:

- make the sizing bactericidal properties;

- increase the shelf life of the prepared emulsion sizing;

- improving the quality of the wool fibres during processing with the application of the proposed sizing.

The technical result of the invention is the prevention of bioforest sizing and, accordingly, prepared on the basis of the emulsion, increasing the shelf life of the emulsion.

This technical result is reached due to the introduction of the sizing, including oleic acid, triethanolamine, sentenal, stearic-6, transformer oil, in the following ratio, wt.%:

oleic acid4,5-5,5
triethanolamine0,8-1,0
sentenal7,0-8,0

bactericidal additives, representing neutralized with caustic soda, the product of the interaction of thiocarbamide, phosphorus trichloride and formalin in the amount of 6.0-8.0 wt.% per 100 wt.% the above composition.

Comparative analysis of the prototype and the proposed invention shows that the total is used in the sizing composition of oleic acid, triethanolamine as components of the emulsifier, mineral oil bases, surfactants for removing static electricity in the fiber production process.

The difference of the invention from the prototype is used in the sizing compositions of surfactants, including sintana and stearic-6 (according to GOST 8980-75 - mix polyoxyethyleneglycol esters of stearic acid), transformer oil mineral oil basis, antibacterial additives, representing neutralized with caustic soda, the product of the interaction of thiocarbamide, phosphorus trichloride and formalin.

Oleic acid and triethanolamine are components of the emulsifier which in interaction with each other (in the production process of sizing) form triethanolamine ester of oleic acid of the following formula:

,

are the different emulsifier. Sintana and stearic-6 form a surfactant composition that reduce friction and pusenje wool in the production process of the fiber, to soften the neck woolen cloth. Transformer oil hydrocracking is a mineral oil based lubricant, characterized by a low content of aromatic carbon (less than 1.5 wt.%) and paraffin-naphthenic composition.

Way to get the sizing is as follows:

1. In the contactor mixer introduce any number of transformer oil, then with constant stirring in the oil add the entire quantity of oleic acid. The mixture is stirred for 1 hour at a temperature of not higher than 25°C. Subsequent operations are performed with constant stirring.

2. In the mixture gradually, in small portions add the entire quantity of triethanolamine (stirring for 2-3 hours). At this stage is the synthesis of emulsifier - triethanolamine soap of oleic acid.

3. Then the temperature in the contactor-mixer gradually (at a rate of 15-20°h) increase to 50°and introducing the resulting solution triethanolamine soap of oleic acid in transformer oil first, the number of cintanya, and then stearica-6, and then stirred for three hours. At this stage, the formation of the surfactant composition.

4. After complete dissolution of all components in the mixture add bactericidal additive, and the resulting mixture was stirred for one hour.

- wool mixtures in worsted manufacture up to 10.

Example 2. Synthesis bactericidal additives.

The method of obtaining bactericidal additive is as follows. Into the reaction flask with stirrer and reflux condenser load 25 ml of 70% (wt.) the thiocarbamide solution, heated to 50°add 36 ml of phosphorus trichloride and incubated for 15 minutes. Upon expiration of the specified time is neutralized with caustic soda to a pH of 6.0. Then enter 40 ml of 37% (wt.) formalin, incubated for 120 minutes at 40-50°C. thereafter, the mixture is discharged, add 250 ml of 15% (wt.) solution of caustic soda.

Loose flocculent precipitate is filtered under vacuum and dried at room temperature to constant weight. End up with 50 g of the product is bactericidal additives. Structure of the substance does not clearly established.

Example 3. Determination of bacteria is innych properties of sizing.

Bactericidal properties obtained according to example 1 of sizing and emulsions prepared on its basis, was performed according to the method described in (lubricating and cooling technological tools for metal cutting: manual /Under the General editorship Sgeneric, AM Berliner. - 2nd ed., revised and enlarged additional Meters: machinery, 1995, 496 C.). Experiments were performed as follows. In one test tube is placed 9 ml of infected used 10% (wt.) emulsion sizing, not containing bactericidal additive. The second test tube is placed 9 ml used 10% (wt.) emulsion lubricant containing bactericidal additive. Then in both test tube add 1.0 ml of the indicator is 0.5% (wt.) aqueous solution of 2,3,5-triphenyltetrazolium chloride (TTX). The contents of the test tubes thoroughly mixed, the tubes are placed in a thermostat and maintained at a temperature of 30±5°during the time required for the appearance of the characteristic color in the test emulsions (1-5 days). Assess visually the presence and intensity of colouring emulsion and determine the score of microbiological destruction of the emulsion. As a result of tests, it was found that upon expiration of the probation period, the emulsion prepared with sizing without bactericidal additive has a limit of the IV-th point bioorganica on V-point scale from 0 to IV, which is says about the unsuitability of the emulsion to further exploitation. The emulsion prepared with sizing with bactericidal additive has a 0-1 score, i.e. the emulsion for a long time suitable for operation.
