Embodiment 1

[0069] Example 1: Recycled cotton (noil) and viscose filament coaxial two-pair net-wrapped composite spinning

[0070] Using the synchronous upper cover and lower support compound spinning method for symmetrical beam splitting and spreading of the present invention, the two bundles of viscose filaments are split according to the above method, and then the yarn is spread, and the coaxial two pairs of nets are wrapped back with cotton fibers After the sliver is composite spun at the nip of the front roller, a smooth composite yarn is formed. The specific process parameters are shown in the table below. The axial and cross-sectional structures of the spun composite yarn are as follows: figure 1 shown. The yarn hairiness index, twist angle, breaking strength, breaking elongation and yarn fineness irregularity of the spun bright and clean composite yarn are listed in the table below. Among them, the spinning rate is very high, which means that there is very little loss of fiber s...

Abstract

The invention discloses a symmetrical beam splitting filament-spreading synchronous upper-covering and lower-supporting composite yarn, a spinning method and application thereof. The composite yarn is a pair of 3*2 shafting double-mesh composite yarn which is formed by compounding after a short fiber whisker strip is wrapped by double filament meshes and halving a filament, that is to say, a two double-mesh wrapping, two-mesh wrapping and coating, double-mesh wrapping and mesh wrapping and coating composite yarn; and the yarn can be used for weaving soft, abrasion-resistant, beautiful and comfortable textile with clear texture, high intensity and pilling resistance and high-level fine fabrics. The method for realizing the double-mesh composite yarn comprises the steps of: adopting a splitter and filament spreading devices both of which are mounted on a ring throstle; symmetrically splitting two beams of the filaments into four beams including two upstream beams and two downstream beams by the splitter; enabling the upstream beams and the downstream beams to enter into respective filament spreading devices for filament spreading so as to form tow paths of upper-covering and lower-supporting filament meshes and clamp as well as wrap respective short fiber whisker strip in a twisting triangular zone; and then compounding to form the double-mesh composite yarn. The method is suitable for spinning of protective, soft, smooth and high-count composite yarns of fibers which are ultra-short, easy to drop scraps and easy to generate flying and shorter and weaker fibers.

Description

technical field [0001] The invention relates to a composite yarn with symmetrical beam splitting and spreading synchronously with upper cover and lower support, the spinning method of the composite yarn, the composite yarn and the application of the spinning method. Background technique [0002] With the rapid development of the textile industry, short and weak fibers such as noil and noil in textile processing increase; the recycling of fibers with poor length and strength in discarded textiles, new ultra-short and fragile fibers Fibers such as kapok and down have begun to be paid attention to and utilized. The yarns spun from these short and weak fibers have low strength, many hairiness and poor quality. This will lead to obstacles to the circulation and ecological utilization of such short and weak fibers. In addition, the existing filaments are too thick for the convenience of processing, and the linear density value of conventional varieties is greater than 30D (denie...
