The invention relates to the field of production and processing of aramid fibers, in particular for finishing complex aramid threads.

There is a method in which processing of polyester fibers use the sizing BUT-2 (TU 2484-014-05744685-2004)containing mineral oil with a flash point not lower than 150C., the ester of a fatty acid and a polyhydric alcohol (emulsifier), alkylpolyoxyethylene (antistatic agent), at the following content, wt.%:

mineral oil 82-88

ester of a fatty acid and a polyhydric alcohol 3-6

alkylpolyoxyethylene 9-12.

There is a method in which to handle the acetate fibers use the sizing a-1 (TU 2484-002-05744685-2002)containing mineral oil with a flash point not lower than 150C, coconut oil, a mixture of esters of fatty acids, a mixture of alkylpolyoxyethylene and alkylphosphates at the following content, wt.%:

mineral oil46-68
coconut oil5-10
the mixture of esters of fatty acids11-20
a mixture of alkylpolyoxyethylene and alkylphosphates9-13
ethoxylated alcohols7-11

The above methods have disadvantages, namely, that the used oil has a low temperature resistance, have the annoying smell of mineral oils, causing the effect of allergies, skin irritation and respiratory organs, have no protection from bioorganica, the absence of which leads to loss of the protective layer and technological appearance of colored spots on the threads in the storage process, which are difficult to remove from the fibers during the final rinse gray cloth.

The tensile strength aramid yarns coated with the sizing A-1, N-02 after textile processing is reduced to (20 - 30)%. This behavior is explained by the data of IR-spectra when measuring the intensities of the absorption bands of the valence (N-H) vibrations in the frequency domain (2800-3500) cm-1. The measurements show a decrease in the relative energy of intermolecular interactions between the benzimidazole groups aramid fiber before (-30%) for a-1 and up (-20%) for N-02.

The task to be solved by the invention is to provide a method for processing integrated aramid threads, eliminating the above disadvantages and provide the necessary level of physical, mechanical, anti-static, termostatic the x property.

The technical result of the claimed invention is to improve conductive properties, protection against bioorganica while maintaining high physical-mechanical properties of aramid threads and exception irritating smell.

This technical result is achieved in that in the method of processing synthetic yarns for textile processing, characterized by applying on the surface of the processing composition containing mineral oil, emulsifier and antistatic agent according to the invention the processing composition further comprises a preservative to protect against Bioorganic, and the processing is subjected to complex aramid yarns with a linear density of not more than 110 Tex, in the process of winding, and use heat-resistant, odorless oil with a flash point of at least 180C, a mixture of fatty acid ester and oksietilirovannykh fatty alcohol as emulsifier, alkylpolyoxyethylene as antistatic agent in the following ratio of components, wt.%:

heat-resistant oil45-60
the mixture of fatty acid ester and
oksietilirovannykh fatty alcohol2030
alkylpolyoxyethylene19.93 per-24,9
preservative0,07-0,1,

the ratio of fatty acid ester and oksietilirovannykh fatty alcohol in the mixture is about 4:1, and as a preservative use derivatives isothiazolones and oxalide.

The use of a mixture of fatty acid ester and oksietilirovannykh fatty alcohol in the ratio of 4:1 allows efficient removal of the processing composition from the fibers at the stage of washing.

The proposed composition of the processing composition has no irritating smell with allergic action.

The recommended degree of application of the processing composition on the thread of 0.7 to 1.5 wt%. The decline of the breaking load in the weaving process does not exceed 15%, and the relative elongation is less than 10%. The composition provides improved conductivity threads by 3-4 orders of magnitude.

Named part of the processing composition after application to aramid fiber provides the increase of the relative energy of hydrogen bonding intermolecular interactions between macromolecules benzimidazole groups aramid fibers at 20-35%. For compositions a-1 and H-02 characterized by the decrease of this index in range (20-30)%, respectively. These the data are confirmed by IR spectral measurement region (2800-3500) cm -1.

Application of the processing composition for aramid fibres, multi - and microfilament with a linear density of not more than 110 Tex.

The proposed method of processing integrated aramid yarns are illustrated in the following examples.

The processing composition is applied on a comprehensive aramid yarn having a linear density of 14.3 Tex, in the process of its coil to form a textile packages (with Kopsov on a reel) on winders type BP-S (Russia), PCW (firm Barmag, Germany). The composition is applied using a roller, which rotates in a bath with the processing composition. Regulation of process parameters, such as speed of rotation of the roller, the speed rewindable thread, the level of the processing composition in the tub, set the desired degree of application of the composition on the thread. In this example, it is 1.5% of the weight.

The data in the table show that the treated declared by the method of complex aramid yarns have high physical-mechanical and heat-resistant properties, reduced antistatic properties due to the use of no irritant smell of the processing composition, providing increased relative energy of intermolecular interaction of hydrogen bonds between the benzimidazole groups aramid fibers at 20-35%, increasing the conductivity of the filaments by 3-4 orders of magnitude with the degree of application of 0.7 to 1.5 wt%.
