Production method of flax blended knitting yarns

InactiveCN101935902AImprove qualityClear and plump appearanceYarnFiberYarn
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.

Processing method and device for spinning single yarns of plied yarn structures on ring spinning frame and yarns

The invention relates to a processing method for spinning single yarns of plied yarn structures on a ring spinning frame. A twisting mechanism arranged at the front ends of a front leather roller and a front roller is adopted; the twisting mechanism consists of the twisting leather roller and the twisting roller which do rotary motion and reciprocating motion; fibers arranged in parallel in fiber strands are twisted under the friction action of the twisting mechanism to form pre-added twisting orientation; two bundles of pre-twisted ring spun staple fiber yarns subjected to twisting treatment are output through a twisting jaw composed of the twisting roller and the twisting leather roller; and the two bundles of pre-twisted ring spun staple fiber yarns are converged and plied in a triangular twisting area under the action of twisting force of cohesive twisting and internal torque force of slivers subjected to twisting finishing, so that the single yarns of the plied yarn structures integrating main body double-strand spiral type and local twisting cohesive type are formed, the strength, abrasion resistance and flexibility of the yarns are improved, the technological process of doubling and plying of the single yarns are reduced, the application range is wide, the operation is convenient, and the large-area popularization and application are facilitated.

Viscose imitation silk yarn production device and spinning method thereof

The invention discloses a viscose imitation silk yarn production device and a spinning method thereof. The viscose roving is drawn to obtain fiber strands, and then the twist generated by a winding system is twisted at the initial twisting point to form an initial viscose spun yarn. An annular twisting belt is set at the front of the front roller. The viscose spun yarn passes between the front and rear side belts of the twisting belt at the initial twisting point. The motor drives the twisting belt to rotate and then twists the passed viscose spun yarn. Function, the twisting degree is transmitted upwards and downwards respectively, and the upper transmission performs pre-reverse twisting on the fiber strands opposite to the twisting direction, so that the initial twisting point is moved up, and the first fiber bundle is obtained to improve the initial twisting section strength, reduce end breakage, and the lower transmission produces pre-positive twist on the spinning section, which greatly enhances the twist of the spinning section. After the first fiber bundle passes through the twisting belt, its own pre-reverse twist immediately matches the spinning The pre-forward twisting twist of the yarn segment is offset, and then immediately re-twisted by the twisting twist to obtain the final viscose spun yarn with high strength and less hairiness.
