WITH

The invention relates to the textile industry, and more particularly to the production of felted yarns used for fabrics, knitwear, nonwovens and for hand knitting.

A known method for producing a shaped yarn with a nap effect, according to which a fibrous component of chemical fibers of linear density 2.2 tex is formed, which is embedded in a wool mixture to create a nap effect on the yarn. The disadvantage of this method is the reduction in the tensile ability of the mixture due to the insertion of coarse fibers and the increase in the complexity of its manufacture.

The closest to the proposed method in terms of technical nature and the achieved result is a method for producing a shaped yarn with a nap effect, according to which a fibrous component (mixture) of chemical fibers with a linear density of not more than 2.2 tex and wool fibers is formed by forming a multilayer bed. Then, the mixture is mixed with the remaining components of the mixture of wool and chemical fibers and a yarn is formed. The fraction in the straightforward chemical fibers of linear density 2.2 tex, creating a pile effect, is not more than 20%.

The disadvantage of this method is the decrease in the tensile ability of the mixture due to the insertion of coarse 2.2 tex fibers, which leads to an increase in breakage. In addition, there is an increase in the complexity of manufacturing yarn, mainly due to the introduction of additional manual operation VJ

tion: composing a bed (mixture) and increasing yarn breakage and, as a result of this, reducing the yield of yarn from the mixture. Yarns with a pile effect formed by chemical fibers of linear density 2.2 tex have a hard neck.

The purpose of the invention is to increase the tensile ability of the fibers and to reduce the breakage of the yarn and fumes.

This goal is achieved in that when forming the fibrous component to create a fashionable effect, chemical fibers with a linear density of 1.1-2.2 tex are used, mainly polyamide fibers and chemical fibers with a linear density of 0.3-0.6 tex are added to them the same breed in the following ratio of fibers in the component, wt.%:

Chemical fibers

linear density

0.3-0.6 tex 15-30

Chemical fibers

linear density

1.1-2.2 tex70-85

Chemical fibers with a linear density of 1.1-2.2 tex are profiled.

The indicated ratio of component fibers is determined by the stability of the process of yarn production and the quality of the resulting pile.

With an increase in the content of average linear density fibers (0.3-0.6 tex) in the component above 30%, the efficiency of pile formation decreases, since these fibers are earned by yarn and do not participate in pile formation.

An increase in the component of the share of high linear density chemical fibers (1.1–2.2 tex) above 85% gives the fabrics and knitwear a stiff neck and reduces the tensile strength of the mixture, causes an increase in yarn breakage and, consequently, a decrease the yield of yarn from the mixture .. ... , .... ,.:. :

In addition, embedding 0.3-0.6 tex of linear density in the effective component of the fibers makes it possible to increase the tensile strength of the mixture, reduce the breakage of the yarn and increase its yield from the mixture. Calculations show that the use of 25% capron fibers with a linear density of 0.32 tex and 75% fibers with a linear density of 1.7 tex in the effective component can increase the reserve of dope ability from 18.2% to.

Processing a component to create a pile effect in yarn does not require the use of special technology and equipment .. ,,

Example 1. To produce a half-woolen yarn with a nap effect of linear density 31 tex, merino wool is taken at least 60 to 40%, nitron fiber 0.33 tex 40%, the fibrous component to create a shaped (pile) effect of 20%.

To obtain a component that creates a shaped (pile) effect, 1.7 tex nylon shiny profiled fiber of linear density is combined with 0.32 tex linear density nylon fiber in ratios (%), respectively: 85:15; 75:25; 70:30 (the best option is 75:25). The connection is carried out when they are formed on a spinning machine through a single die, having various profiles and hole sizes, which automatically ensures uniform mixing of various fibers. The resulting component was introduced into a mixture of wool and nitron fibers on a baking powder and bed aggregate without making up a bed.

Example 2. To produce a semi-woolen yarn with a nap effect of linear density of 125 tex, merino wool is taken at least 60 to 40%, nitron fiber 0.33 tex 40%, a fibrous component to create a shaped (pile) effect 20 %

To create a fluffy effect, a 2.2 tex shiny profiled nylon fiber was used in conjunction with a 0.4 tex linear density nylon fiber in ratios (%), respectively: 85:15; 75:25; 70:30, (the best option is 75:25). The combination of these fibers and the preparation of yarn with a pile effect was carried out according to Example 1.

The table (options 2a, 26, 2c) shows the physicomechanical and technical and economic indicators of a yarn with a linear density of 31 tex compared to the yarn obtained by the prototype (option 1); (options Za, 36, Sv) —presented are the physico-mechanical and technical and economic indicators of yarns of linear density 125 tex compared to yarns of the same linear density obtained from the prototype (option 1a).

As can be seen from the table, yarn obtained, for example, using a nylon fiber with a linear density of 1.7 tex and 0.32 tex in accordance with 75:25 as a pile effect component.

accordingly, in comparison with the prototype, it has a strength of 12-15% higher, elongation increases from 12.6% to 13.6%, breakage decreases by 40%.

The laboriousness of manufacturing is also reduced and the amount of burns is reduced. The resulting yarn has a softer and better pile. Thus, the method for producing a shaped yarn with a nap effect allows, in comparison with the prototype, to significantly increase the tensile ability, reduce breakage and burns, and reduce the complexity of manufacturing.
