F.-ly, 2 tab., 8 Il. The invention relates to the textile and apparel industries textile industry and can be used for processing yarn, cotton, viscose staple fibre, Dacron, wool and other threads, used in the manufacture of textile and clothing products of both regular and special, footwear, leather goods.In modern clothing and textile machines such as spinning the s yarn, textile and sewing thread, especially along its length, with no bulges and fluffiness. General loss of strength from the testing of yarns and threads on technological transitions textile machines and from education Shuttle stitches when moving on technological transitions sewing machines ranges from 12 to 40%, the Main factor influencing the loss of yarn strength and yarn is significant frictional effects, leading to loss of friction 20%
Known aerodynamic method of processing cotton threads  consists in the fact that the thread wound with packing, impregnated under tension technological solution, wring out, and before drying effect flow circular air jet directed opposite to the motion of the thread at an angle 40o-50oto its axis with a speed of 2 to 16 m/sThe disadvantage of this method is that the air flow acting on the perimeter surface macroalgae thread, provides adhesion lonely, loose fibers along the generatrix line, thereby creating separate zones on the convexity of plies of thread thickenings that form natural barriers to the passage of the threads on technological transitions textile and Sha located on the surface napolitana thermosetting resin is an obstacle to passage through the combined holes in the textile and sewing machines. Place thickening cause thread breakage.Known hydrodynamic method  processing yarn and cotton sewing thread, that thread is processed technological solution under tension hydrodynamic rotating flow solution, wrung out and dried. Combining the rotation of the solution and the direction of twist, achieve a more uniform thickness throughout the length of textile and sewing thread and yarn. But this thread is inherent in almost all the disadvantages of the previous method, namely: increased stiffness, deterioration of air in the process.The closest analogue (prototype) of the invention is a method of processing yarn and sewing thread  including wrap them with yarn package, the application of technological sizing of the drug in a cone-shaped vessel by contacting the yarn and thread with beads and drying.The disadvantage of analogue is that of a geometric body in the form of balls contain amorphous, low-melting point paraffin, synthetic rubber heat-resistant low-molecular-weight grades a, the product N-22, beeswax, a composition which on the one hand easily loses its original geometry, plastic and abilities quickly and easily transferred to the surface of the yarn, textile and sewing threads, loosely fixed on their surfaces. Particles come easily from the surface of the filaments and the yarn subsequent use, and the use of scarce food and medicinal raw material does not allow to introduce widely nor in the garment, either in the spinning industries.A common disadvantage of all the methods is that the analogues on the one hand provide a liquid processing in the form of impregnation in okonko, followed by drying in an offline process, on the other hand the use of compositions that do not provide a full treatment of the surface of the yarn, textile and sewing thread. The way the prototype provides odnotsiklovoy processing, but the application of thermoplastic polymer in the form of fine particles makes this decision technologically barely acceptable because of the frequency of refilling the vessel, the loss of geometric shapes and adhesion of the polymer beads, the deficit of the original products.The technical result is the alignment of the yarn and the stabilization of its geometrical thickness, reducing friction on technological transitions textile and sewing equipment.The technical result is achieved due to the alignment of the yarns and threads along the length of the product, the elimination of distinct knots with bringing the yarn and thread in cross section to the geometric shape due to the centripetal forces of impact of the balls on the surface of the product, attach weakly pinned single fibers by use as a process agent with a level of adhesion of the sizing of plant origin, contributing simultaneously to the decrease of the coefficient of tangential resistance and attaching fibers to the warp yarns and yarns in comparison with an amorphous drug sedentary consistency.Theoretically proved that the filling volume to the value of geometric objects and a better impact on the product surface. It has been experimentally confirmed that the hairiness of yarns and threads, depending on the amount of filling balls tapered capacity obeys normal distribution curve, where the area with filling volumes from 1/6 V 2/3 V preferred.In Fig. 1 shows a schematic diagram of a spinning and twisting machine of Fig. 2 a device for processing yarn, textile and sewing thread; Fig. 3 schematic diagram of the installation of the device on the head of the sewing machine of Fig. 4-6 shows the cross-sectional area of the yarn processed: on existing technology, the method prototype, developed technology, and Fig. 7, 8 shows the diagram of palipane-slides yarn, treated as on existing technology and developed.The device for implementing the method in a spinning and twisting machine operates as follows.After twisting the roving passes through the suction device 1, into micko a given linear density, then through the thread guide 2 to the ear 3. During the rotation of the cob 3 with it comes the thread 4, which rotates drags Micco in the Central channel of the spindle 5, causing it to rotate around its own axis and turning her joining wypadami and descending from the cob strands. On the way from the top of the spindle to the final pair 7 vypadala and coiled strand, receiving rotation from the same spindle, twist and turn twist-back direction of turns compared to what was reported back to the strand. The area between the final pair 7 and the winding mechanism 8, the yarn is processed in a cone-shaped container 9 is placed in it by the balls 10 (Fig. 2). The direction of rotation of the vessel coincides with the direction of twist of the yarn and the surface of the yarn exercise geometric volumes in the form of beads of glass, plastic, metal and so on greased skim sizing of plant origin. Joint integrated mechanical-physical-chemical effects reduce the hairiness of the yarn, the alignment in thickness, the thickness decrease.In Fig. 3 shows a device for implementing the method on the sewing machine implements a scheme to transmit motion through two gears, one of which is installed on the main shaft of the machine and represents in statics the following elements: thread 1, spatialdata from the reel (Fig. 3 not shown), the thread guide 2, hole 3, a top cover 4, a cone-shaped rotating tank in the form of a funnel 5, kapelln the x2">The device operates as follows.Thread 1, sativas from the reel (Fig. 3 not shown) through the thread guide 2 is sent into the hole 3, where the pipeline from a dropper top cover 4 cone-shaped rotating the vessel in the form of a funnel 5, which receives the rotation of a bevel gear transmission, bevel gears 9 and 10 of the main shaft of the machine 11. The gear 9 is rigidly connected to the cone-shaped rotating container in the form of a funnel 5. The capacity of the thread guide 5 and 2 are mounted on a support plate 8.Speed cone-shaped rotating the vessel is designed in such a way that is in the tank balls when increasing the rotation speed has a significant impact not only in the direction of the twist, but also on the geometrical properties of the yarns and threads, but due to the insertion in the capacity sizing of plant origin and centripetal effects of beads on the yarn is smooth backward from the surface of the yarns and threads single fibers and make them stick. This joint mechanical-physical-chemical effect stabilizes the geometrical parameters of yarn, textile and sewing threads, smoothes nodules, removes loose fiber and the reduction ratio of the tangential resistance to technological transitions textile and sewing equipment.Examples of the method.The method was tested in laboratory conditions in the pilot plant modeling process spinning and twisting machines. Tests were conducted on cotton yarn with a linear density of 16.5 Tex produced by industry standard OST 17-96-86. The rovings wound with packing and after the implementation of technological operations for forming twisted yarns, the latter being received in a conical vessel with unyielding balls that are served fat-free sizing of plant origin. During the rotation of the cone-shaped tank, due to centripetal forces, the beads was carried out by applying a lubricant to the surface of the yarn. A visual representation of how mechanical and physico-chemical effects of geometric objects in the form of balls, for example, of glass or metal, with the sizing of plant origin gives a measure of yarn hairiness, characterizing the state of the front surface of the yarn. Evaluation of the hairiness of the yarn was carried out in accordance with the recommendations outlined in the methodology  the Results are shown in table. 1.As clearly seen from the results, praut influence on the breaking load of the yarn, because the measurement error is within the error of the experience. At the same time quality indicator yarn, hairiness, decreased in two times, the yarn is compacted, as evidenced by a decrease in the relative elongation at break by 10.7% compared with conventional technology.In parallel studies for contactless determination of square cross-section yarns and threads  compare ways of processing yarn, suggests that the geometry of the cross section of the yarn with the reliability of 0.8 to 0.9 is approaching a section of a circle (Fig. 6), while the yarn processed according to the traditional technology and prototype approaches oval, resembling an ellipse (Fig. 4, 5). Changing not only the cross-sectional shape of the yarn processed according to the compared technologies, but also the quantitative value of the area: according to traditional technology, the average size was S 5,2910-2mm2with a spread of 2,6810-2to 8,0310-2mm2, while the developed technology'S 5,710-2mm2with a spread of 3,6810-2to 7,6710-2mm2.Studies to determine the thickness of the yarn showed that geometrical parameters after the treatment change. Yarn, processing is compared with the method of the prototype, which is in good agreement with the change of the sectional area of the yarn, the relative elongation (Fig. 4, 5, 6).On the nature of the surface condition of the yarn can be judged not only in terms of hairiness, and charts palipane-slides that reflect the same state of the surface 
In the diagram (Fig. 7) presents a record of palipane-slides yarn processed according to industrial technology. Rare protrusions and depressions show unevenness in the geometric parameters of the yarn length and the presence of significant hairiness on its generatrix. Diametrically opposite picture on a chart palipane-slides yarn (Fig. 8), handled by the technology of using a cone-shaped vessel, the geometric shapes in the form of balls and oil of vegetable origin. Smoothed contour, without rare projections and depressions suggests that technological transitions decreased coefficient of tangential resistance and, consequently, decreased hairiness of yarn.An example of the method for sewing threads.The method was tested in laboratory conditions on the cotton thread series "Extra", line PLOThe results of the tests are presented in table. 2.As can be seen from the results shown in table. 2, the breaking load of sewing thread and elongation at break are different within the error of the experience and do not exceed 5% Significant difference is the length of the seamless transfer of the seam, which is more on the technology developed by 46% compared to traditional. All other studies with a sewing thread confirmed mainly new technology.A significant difference and advantage of the developed method compared with the prototype is that the process is continuous, the set of technological regimes are maintained constant from beginning to end processing. The sewing machines less ushitsa the needle thread, decreases the temperature of the needle, decrease of the friction force on technological transitions and multiple passes of thread through the eye of a needle, less loss of strength thread the needle, and, consequently, increases the strength of the weld. 1.
