SHAPED YARN

The utility model relates to the textile industry, in particular, to the production of fancy-woolen yarn with iridescent effect, intended for the production of knitted and haberdashery products, household fabrics.

Known shaped yarn with a multifaceted variety in structure and appearance, obtained by mixing multi-colored fibers during spinning, by combining color effects applied to the thread in the process of dyeing, printing (stuffing), as well as the use of shaped twisting of colored component yarns Koritsky K.I. . “Production of fancy yarn, M: Gizlegprom 1955, p.6.

Closest yarn with uniformly alternating effects, which is twisted yarn made of several colored components of different linear densities and varying degrees of twist, is the closest in technical essence and the achieved effect, as a result of which the thread has the form of a spiral (Figure 1).

State of the art

For example, a mouline thread yarn of two colored threads 1 and 2 is twisted a second time in the opposite direction with colored or severe thread 3 (a and b).

For a greater variety of color effects, twist the mouline thread 1.2 yarn with a single-thread stern yarn 3 around a thick core thread in the direction opposite to the last twist direction (c).

.

Fig. 1. Floss yarn with uniformly alternating effects in l. Shaped yarn is produced on twisting machines of shaped twist: by a single-process method on machines of the Prenomit type, working on the principle of a “hollow spindle; in a two-process way on ring twisting machines of the type “PL-31 and of the company“ Textima. The shaped effect on the yarn is formed due to the different feed speeds of the torsion zone of the rod and surge components, as well as due to different frost density and color of the twisted threads. The use of known types of fancy yarns does not allow to expand the assortment capabilities of woven and knitted products. The essence of a useful model The basis of a useful model is the task of creating a fancy yarn, which will provide a technical result, which consists in expanding and enriching the assortment of fancy yarn and products from it. This technical result in fancy yarn for knitted and woven products is achieved only by using machines operating on the principle of a hollow spindle. The proposed fancy-knit yarn consists of a core containing several components connected by false torsion, the number of which must be at least two, and a braid (or winding thread). For the formation of the core can be used: 1. Yarn single or twisted with a linear density of 8.0 tex: 200 tex, different colors, different in raw material composition: natural fibers (cotton, linen, wool, etc.); chemical fibers of linear density 0.11 tex: 2.2 tex (viscose fiber, viscose high modulus, polyester, polyamide, polyacrylonitrile, polypropylene); mixtures of natural and chemical fibers: polyester fiber 50 - 70% cotton fiber 50-30%; polypropylene fiber - 30-50% wool fiber - 20-10% viscose fiber - 50-40% polyacrylonitrile fiber - 70-50% flax fiber (cotonin) - 30 - 50% 2. Viscose, polyester, polyamide, polymeric yarns, etc. .d painted, linear density 50 tex - 144.4 tex. 3. The combination of single, twisted yarn (possibly fancy previously) and threads in various versions: in quantity, color: sho and linear density.

4. The braid can be a single yarn of linear density 12.5-25 tex, severe and dyed, or complex yarns of linear density 516.7 tex. A prerequisite for achieving the claimed technical result is the absence of tension or

ineffective tension control during the formation of fancy yarn. The free passage of the core components in the first torsion zone, the pulsating distribution of the twist due to the friction forces of the core-spindle pair provides an uneven arrangement of the turns of the core components, which is evenly fixed in the second torsion zone by a braid (or an fixing thread). On the surface of the obtained yarn, one, another, etc., is uneven and irregular in length. core components (Figure 2), the result is a fancy yarn with an iridescent effect.

Physicomechanical parameters of fancy yarn with iridescent effect and known (flossy, shtpornoj, flossed, frot with a surge 1.1, which include similar components) fineness, surpassing in some indicators and sufficient to ensure the process of its processing in knitting and weaving (see table 2).

The use of various components as the core allows you to get fancy yarn with an iridescent effect, which combines the aesthetic and comfortable properties of natural fibers with the strength of chemical fibers and threads.

Thus, the use of fancy yarn with iridescent effect expands the assortment opportunities in weaving and knitting industries, as well as improves the hygienic and aesthetic properties of the finished products, allows you to create comfort and attractiveness that correspond to the direction of fashion and technical aesthetics.

Information confirming the possibility of implementing a useful model

Shaped yarn with iridescent effect can be made at textile enterprises using modernized spinning and twisting machines PK-100, Prenomit machines using natural and chemical fibers, polyester viscose, polyamide yarns, various colors and linear densities.

Claims (1)

Spun yarn consisting of several colored components, characterized in that its core contains components of the same or different linear density of various raw materials that are unevenly connected by false torsion, on the surface of which one or the other component irregularly prevails, and the braid that fixes the effect.
