Composition for waxing is produced textile fibers

 

(57) Abstract:

Usage: in the textile industry to improve the ability of cellulose, wool, flax fibers and their mixtures with chemical fibres to processing in spinning, knitting and weaving industries, for example in the process of winding on winding machines while reducing abrasive and hydrogen wear siteprovides metal parts of equipment. The essence of the invention: composition for waxing is produced textile fibers contains, wt%: copper oleate 0,05 - 0,50; oleic acid 0,05 - 0,50; paraffin to 100. The composition may contain as plasticizing additives up to 5 wt.% industrial or other mineral oils. To prepare the composition slowly on a water bath heats paraffin up to 60 - 70°C and with stirring, add the remaining components. Poured into steel molds and molded by cooling parafilaria rollers. The composition is applied to a moving filament in contact with the rotating rollers. The wear rate of metal siteprovides parts of the equipment during use of the composition is reduced 1.8 - 2.7 times. The intensity of the electrostatic field in the area of contact of the thread with the metal is and the 15 - 20%. Reducing dust. table 1.

The invention relates to textile production, namely technology waxing is produced fibers, including in the form of thread and yarn, with the aim of improving their ability to recycle, for example in the winding process before spinning, winding the yarn in knitting production, etc.

Known composition for waxing is produced yarn containing paraffin, spun butter, cationic drug Alcamo OS-2 and glycerin.

Processing yarn known composition though and reduces abrasive wear siteprovides parts of the equipment in contact with the moving yarn, however, does not resolve intensive hydrogen wear them, as a result of complex physical and chemical processes on the boundary of the moving fiber - metal.

Closest to the invention to the technical essence and the achieved result is a composition for the treatment of textile fibers, containing, by weight. % : the alkali metal stearate 30-45; paraffin 10-18; oleic acid 10-15; velocitee oil 2-5 wt.%, mono - or diethanolamide synthetic fatty acids10-C1615-25 wt.%.

This composition, as mentioned above, improves with frictiony and antistatic properties. It also reduces the abrasive wear of metal siteprovides parts. However, as the previous composition, it does not eliminate hydrogen wear of the equipment. In addition, the protective film formed on the surface of the fiber and machine parts, using both known compounds is not strong enough, which reduces the efficiency of known compounds.

The objective of the invention is to reduce wear of metal siteprovides details of the equipment and reducing breakage of the fibers during processing.

This task is solved by a composition for waxing is produced textile fibers, containing paraffin, salt of the fatty acid and oleic acid, and the composition contains as salts of fatty acids copper oleate in the following ratio, wt.%: Copper oleate 0,05-0,50 Oleic acid is 0.05-0.50 Paraffin Else

When moving threads, has not been processed offer the composition, due to the continuous process of friction in the contact zone of the filament and the metal parts of the equipment in a region of high temperature. On the one hand, increases thermal mobility of the atoms and ions that are located in the nodes of kristallicheskie create some excess energy they have left their positive balance and moved into adjacent interstices, forming a vacancy. On the other hand, when the processing thread previously known compositions of the process of friction promotes destructive phenomena as components of the compositions, and the environment and is accompanied by release of a large number of free atomic hydrogen.

Selected atomic hydrogen, having a high chemical activity, diffuses in the space of new vacancies in the crystal lattice of iron molecules. Since the existence of hydrogen in the atomic state lasts only a short time, hydrogen atoms are introduced into the crystal lattice of the iron molecules recombine into molecules that cause the process of "swelling", lead to gas corrosion of the surface layers of the metal and, as a result, the embrittlement and fracture, i.e. hydrogen wear.

When the moving contact of the fibers treated with the proposed structure, with the metal parts of textile machinery salt MediaLingua acid, adsorbed on the metal surface in the contact zone. Because copper is in a range of voltages has a positive electrode potential with respect to electrode potential of iron, the latter the result of an oxidation-vosstanovitelnoi. As a result, the surface of the workpiece in the area of frictional contact, the formation of the copper film. Moreover, the local wear of the formed copper film is its constant self-healing due to the flow on the exposed parts of the metal surfaces of the above-mentioned reactions. Thus, the entire surface area of frictional contact of the parts during movement of the fiber is formed copper film is self-healing, on the one hand, practically does not increase the concentration of pure hydrogen in an atomic or molecular state, and on the other hand, the formed copper film is self-healing because of its positive normal electrode potential relative to the electrode potential of hydrogen prevents the diffusion penetration of hydrogen into the metal.

Thus, such a protective film can virtually eliminate hydrogen wear of the metal surfaces of the parts of the equipment.

In addition, the film formed has a significant impact on reducing abrasive wear parts textile machinery due to the fact that this film has a sufficiently high pedarnig areas and completely cover the most loaded parts of the metal surfaces of the equipment.

In addition discovered that by reducing the intensity of the electrostatic field in the area of contact of the thread with siteprovides parts decreases their breakage during processing into products, as well as pollution due to static attraction of dust particles from the environment.

The proposed structure can be used for waxing is produced flax, cotton and wool fibers, and mixed natural and chemical fibers or made of these yarns and yarn.

As a known target plasticizing additive composition may contain up to 5 wt.% mineral oils, such as, for example, industrial oil AND brand-40A (GOST 20799-75). It is introduced to reduce brittleness in the case of use in the composition of food paraffin. When using technical paraffin additive is not administered.

The composition is prepared as follows. First slowly heated, for example, in a water bath paraffin 60-70aboutWith and while stirring add the copper oleate and oleic acid, and if necessary mineral oil. Stirring is continued until complete homogenization of the composition. Then the composition in a heated form is poured into steel molds, Okla extracted from the shape of the extruded and used for application to a moving fiber in contact with a rotating roller-known method.

The invention is illustrated in examples 1-4 and table in which the data tribotehnichesky tests according to GOST 1751123. All of the examples in the thread after waxing is produced processed for reeling machine with a speed of 200 m/min for 420 min, i.e., the total length of the friction 84000 m contact Force threads to block 4H.
