The invention relates to the field of processing of wool, wool fiber and its mixture with chemical fibers. Can be used in the textile industry, namely in the processing of wool, fibers of different origin and tissues.

The manufacturing process includes a step of washing the wool, causing the fat content in it is reduced to 0.3 to 0.8%, which is not sufficient for the implementation of the spinning process. Therefore, the process provides for oiling wool by applying special funds - spinning oil (lubricant). Of particular importance is the oiling cloth when spinning, as the use of spinning oil improves the adhesion of the fibers to each other, improves their ability to slide, prevents breakage of the fibers, the formation of feathering, lower quality wool and eliminates the technological problems encountered in the spinning process (for example, thread breakage). Proper selection of effective sizing allows to obtain the above-mentioned technical result.

For oiling worsted yarn recommended (Schoenfeld N. Nonionic detergents, - M.: Chemistry, 1965, - p.á305) the flow of lubricant in the amount of 0.5 to 1.5% by weight of the fibers for worsted yarn - 5-7%.

We know a lot of songs for oiling on the basis of mineral oil. In p myshlennyh conditions of the spinning oil is used in - oil emulsion water. In most cases, a water emulsion of the oil contain 15-20% oil (Schoenfeld N. Nonionic detergents, - M.: Chemistry, 1965, - s).

After maturing processed sizing tool wool have it shaded from the sizing. The complexity, the duration of this process, the effectiveness of the cleaning and consumption of wash water depend on the quality of the means used.

For oiling chemical fibers in the finishing process and fast use described in (Reference chemist, L. Chemistry - V.6, s-435) compositions that include a mixture of sulfated natural fats and oils with mineral oil. As an emulsifier for mineral oils used anion active substance.

There is described a means for oiling textile yarn when it is rewinding, consisting of mineral oils (liquid paraffin) (80 wt.%), oleic acid (14 wt.%), triethanolamine (6 wt.%) and white spirit in the amount of 10-12 wt.% by weight of sizing.

Common features of known oil and offer tools is the use of various oils, anion active and non-ionic emulsifiers.

It is known as described in (Schoenfeld N. Surfactants based on ethylene oxide. TRANS. with it. / Ed. by N. N. Lebedev. Ed. 2-E. - M.: Chemistry, 1982. - s.) means for oiling elocon, which includes a neutral oil (peanut) and fatty acids (oleic). There is also the composition for oiling fibers comprising a mixture of anionic and neinogennye surfactant.

The composition of the lubricant based on mineral, animal or vegetable oil with added oxyalkylene higher alcohol or ether of a polyhydric alcohol is known from the Patent 5269950 U.S. Appl. 12.11.1991, publ. 14.12.93).

Common features of the above sizing and offer tools is also use in their composition base oil base and anion active and non-ionic emulsifiers and stabilizers.

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 are surfactants (for example, Sintana).

Common features of known size and proposed drug is the use of Cintanya.

Known (U.S. Pat. U.S. No. 2730498) the composition of the textile base oils are mineral oils, oksietilirovannye the th lauric acid, dietilfosfat, ether triethanolamine and a fatty acid of coconut oil, triethanolamine and diaminophenol.

Common features of known size and proposed drug is content in their composition of the oil and triethanolamine.

From (TU 6-14-999-80) famous "Sizing B-73", which includes mineral oil, oleic acid, sulfonated castor oil, triethanolamine, Aleax 5 Xylan About or monooleate glycerin.

Common signs of this sizing and offer tools is the use of the composition of the oil base and anion active and non-ionic emulsifiers.

Similar to the proposed drug is a Lubricant for synthetic, mostly acrylic, fiber described in (.RU No. 2093627, publ. 20.10.1997). This means for oiling contains, in wt.%: mineral oil 6,64-9,83; ethoxylated stearic acid with an average degree of oksietilirovannye 6 0,1-0,2 (Stearic-6); blend (acidication) methylethylenediamine of benzosulfimide containing alkyl radical 16-18 atoms (Alcamo OS-2) 0.01 to 0.05; polietilenglikolya esters of isononylphenol medium oksietilirovannye 12 (neonol AF 9-12) 0,01-0,03; dibutyl 0,01-0,03; ammonium ferrocyanide 0.04 to 0.05 and water the rest up to 100.

Common features of known sizing the proposed tool is the use of mineral oil, Stearica-6.

The main disadvantages of the emulsions prepared from the above means for oiling are not sufficiently high antistatic and dispersion properties, foaming, exfoliating, bioforest, corrosivity, high reagent consumption and oil. Washing wool and products made from it in some cases is associated with high costs of water and material resources.

The closest (prototype) to the technical essence and the achieved effect to the claimed means for oiling is known from (chemist's Handbook, L. Chemistry - V.6, s) sizing textile yarns, which includes vaseline oil (84 wt.%), oleic acid (3 wt.%), triethanolamine (1 wt.%), emulsifier OP-4 (6 wt.%) and anti-static agent Storax-6 (6 wt.%).

The disadvantages of the known means for oiling (prototype) are:

is not sufficiently high antistatic and dispersion properties (foaming and exfoliating),

- exposure bioporazheniya during storage and operation,

- high corrosion activity.

Object of the invention is the expansion of the range of means for oiling wool, wool and mixed fibres with good performance properties, stabilization of the technological process of processing of wool.

SUBSTANCE: method is characterised by applying on the surface of the complex aramid thread of the processing composition comprising mineral heat resistant odorless oil with a flash point not less than 180°C; a mixture of fatty acid ether and oxyethylated fatty alcohol as emulsifier, alkylpolyoxyethylene phosphate an antistatic agent and a preservative to protection from biological damage with the following ratio of components, wt %: heat-resistant oil - 45-60, a mixture of fatty acid ether and oxyethylated fatty alcohol - 20-30, alkylpolyoxyethylene phosphate - 19.93-24.9, preservative 0.07-0.1. The ratio of fatty acid ether and oxyethylated fatty alcohol in the mixture is 4:1. The derivatives of isatiozolones and oxalidines are used as preservative.

EFFECT: increase in electrical conductivity properties, protection against biological damage while maintaining high physical and mechanical properties of aramid threads and exclusion of irritating odor.

SUBSTANCE: invention relates to the use of particles consisting of a core and a shell for coating the thread or textile material with them, to restrain or prevent wicking of water into the said thread or textile material. The particles are described, consisting of a core and a shell, for restraining or preventing the wicking of water into the thread or textile material, where the said particles have an average diameter of 10-300 nm and a mean-square deviation σ which is at least 10% of the average value, in which the shell of the particle consisting of a core and a shell comprises a copolymer of a vinyl aromatic monomer and a maleimide monomer with a glass transition temperature Tg of from 120 to 220°C. Also the thread or the textile material is described, containing aramid threads provided with a finish preparation containing diglyceride or triglyceride obtained from glycerol which is esterified with saturated or unsaturated fatty acids containing 6-20 carbon atoms, where the finished thread or textile material is provided with the above mentioned particles.

EFFECT: prevention of wicking of water in the textile material.

FIELD: textile industry, in particular lubrication of wood, wood fiber or mixtures thereof with synthetic fibers.

SUBSTANCE: claimed oil-based agent contains oleic acid and triethanolamine. As oily base transformer oil is used. Compositions may also contain one or two antistatics, emulsifier and doping agent. Moreover composition additionally contains 0.1 % ampicillin aqueous solution in ethanol in amount of 0.001 % (based on composition mass).

EFFECT: agent of improved physical and chemical characteristics, decreased foaming and delaminating, decreased corrosive activity and biological affect; reduced antistatic and emulsifier consumption.
