Yarn for woven and knitted products and how you can get

 

(57) Abstract:

The invention can be used in the textile industry and help to improve the quality of the yarn and to improve the technological process while expanding the range of manufactured from yarn finished products by reducing breakage and increase the equilibrium of the finished yarn. The yarn contains 30-85 wt. % chemical fibers and 15-70 wt.% korotkostebel flax fibres and with a linear density of 0.37-0.89 Tex and 2.1-4 Tex. According to the method of conducting the mixing 30-85 wt.% chemical fibers and 15-70 wt.% korotkostebel flax fibres and with a linear density of 0.25-4 Tex. After blending them processed emulsifying agent, which is used as a drug on the basis of paraffin emulsions concentration of 0.3-1.0%. 2 S. p. f-crystals, 1 table.

The invention relates to the textile industry, in particular the production of yarn used for woven and knitted goods.

Known yarn for woven and knitted goods containing a mixture of korotkostebel flax fibers and chemical fibers (Tarasov B. N., etc. Manufacture of flax-containing yarn and fabrics based on it, the Textile industry, 1998, N 3, the application, dostovernogo flax fibers and chemical fibers, the formation of fibrous tape and then the subsequent yarn (Tarasov B. N., etc. Manufacture of flax-containing yarn and fabrics based on it. The textile industry, 1998, N 3, Appendix C. 6-7).

A disadvantage of the known technical solutions is that substandard humidity korotkostebel flax fiber leads to certain difficulties in the processing of it into yarn, resulting in the observed lack of conditions for the implementation of the technological process of production of the yarn, and therefore the products produced from the yarn, are not good indicators of structural and deformation characteristics such as hairiness, shimonthebest and others.

For best processing and holding of the technological process of production of yarn containing flax fiber, the last moisturize in special areas at certain temperatures within 18 to 36 hours. Cotton companies this method of processing flax fiber is not feasible due to the complexity of the process.

The task of the group of inventions is the creation of yarn for woven and knitted products and how it is received, providing the irenie range produced from this yarn finished products by reducing breakage during the spinning and improve the equilibrium of the finished yarn.

This technical result in the yarn for woven and knitted goods containing a mixture of korotkostebel flax fibers and chemical fibers is achieved by the fact that korotkostebel flax fiber has a linear density of 0.37-0.89 Tex and 2.1-4 Tex in the following ratio, wt. %:

korotkostebel flax fiber - 15-70

chemical fiber - 30-85

This technical result in the method of producing yarns for woven and knitted goods, including blending korotkostebel flax fibers and chemical fibers forming the fibrous tape with the subsequent reception of the yarn is achieved by the fact that after mixing of the fibers subjected to the processing of the emulsifying agent, which is used as a drug on the basis of paraffin emulsions concentration of 0.3-1.0%, while korotkostebel flax fiber has a linear density of 0.25-4 Tex in the following ratio, wt.%:

korotkostebel flax fiber - 15-70

chemical fiber - 30-85

Use korotkostebel flax fibers with a linear density of more than 4 Tex impractical in connection with the violation of technological process, as too large linear tightly tapaninaho flax fibers with a linear density of less than 0.25 Tex impossible due to the lack of conditions to achieve a technical result. The ratio of these components is selected depending on the purpose of the resulting yarn.

The proposed method is as follows.

Natural and chemical fibers, each individually pre loosen and then mixed. As a natural fiber used korotkostebel flax fiber, as well as chemical fiber use, or viscose rayon fiber, or high modulus viscose, or polypropylene, or polyamide, or polyester fiber length of from 25 to 80 mm Mixed fibers forming the fibrous tape then get the yarn on a spinning machine. The whole technological process is carried out for cotton spinning equipment. After blending the last processed emulsifying agent, which is used as a drug on the basis of paraffin emulsion concentration of 0.3-1.0%. As a result of such processing korotkostebel flax fiber acquires properties that enable the further processing korotkostebel flax fiber to obtain a linear density of up to 0.25-4 Tex. This linear density allows vypadate of a mixture of these Moloko and chemical fiber 30-85, yarn with improved characteristics, such as shimonthebest, hairiness.

Examples of the method presented in the table.

As can be seen from the table in the result, the method breakage of the yarn in the process of knitting below 25-30%. The nonequilibrium yarn is reduced in 2 times.

The invention allows to obtain a yarn of higher quality for the manufacture of a wide range of costume-dress destination for cotton spinning equipment while reducing breakage of the yarn.
