Problems solved by technology

[0002] Flax fiber has many characteristics such as hygiene, comfort, coolness, hygroscopicity, antibacterial properties, etc., so its fabric is highly praised by modern people, but flax fiber itself Some of the weaknesses, such as many hemp particles, uneven fiber length, large dispersion of fineness, low fiber elongation at breakage, and easy wrinkling of the fabric, have seriously restricted the improvement of product quality.
In order to improve the quality of flax products, professionals have made a lot of efforts, but the effect is half the result without changing the process raw materials, especially in terms of spinning fineness, it is more restricted, and the product quality is difficult to improve
In the experiment, we found that the use of blended yarn can make the fabric soft and fluffy, which can effectively make up for some deficiencies of the flax fiber itself, and can well meet the requirements of high-count blended products. It is very feasible to improve the quality of existing flax fabrics by blending other blended fibers with good complementarity and selecting the corresponding blending process. This method can open up the development space of high-quality flax light knitted fabrics, which is a very important subject, there are few research results on this subject

Abstract

The invention discloses a production method of flax blended knitting yarns. In the method, flax and modal fibers are blended according to a ratio of 15:85 to 85:15. The method comprises a spinning process and a rotor spinning process. The modal fibers selected in the invention are the most ideal material for light and thin knitted fabrics for their sweat-absorbing, thermal-insulation and cooling properties and integration of the comfortableness of cotton, the drapability of adhesive, the strength of terylene and the handfeel of real silk. The flax-modal blended knitting yarns exploit development space for high-quality flax light and thin knitted fabrics. Although the flax and modal fibers are susceptible to generating hairiness, the rotor spinning used in the invention is one-step bobbin forming and therefore reduces the hairiness of finished fibers and ensures the knitted fabrics are clear and full in appearance. The rotor spun yarns also have the advantages of few yarn faults, high elasticity, pilling resistance, wear resistance and the like. The method has the advantages that: the process flow is short; the cost is low; high grade flax knitting yarns with high balance of various performance indexes such as high fineness, little hairiness, yarn levelness and soft handfeel; and the application value in textile processing field is high.
