AI Technical Summary
The existing polyester fibers are poor in hygroscopicity, which limits their application. Although the fabrics prepared by elastic fibers have good wear comfort, it is difficult to achieve good elasticity and imitation cotton and linen effects at the same time.
The core yarn consists of twisted spandex filaments and Sorona fiber yarns, and the outer side of the core yarn is wrapped with ultra-imitation cotton polyester fiber and imitation bamboo stick yarns. The ultra-imitation cotton polyester fiber and imitation bamboo stick yarns are spiraled in the opposite direction.
It achieves good elasticity and hygroscopicity of the fiber, and also has the effect of imitation cotton and imitation linen, improving the wear comfort and aesthetics of the fabric.

Abstract
Description
Technical Field
[0001] The utility model relates to an elastic cotton-linen imitation polyester fiber, belonging to the technical field of chemical fibers. Background Art
[0002] Since its introduction, polyethylene terephthalate (PET) fiber has developed rapidly due to its excellent performance, and its output has become the world's top synthetic fiber. And the fabrics prepared by it have the advantages of wrinkle resistance and good stiffness, so polyester fiber is widely used in clothing and home textiles. However, the application of polyester fiber is limited due to its poor hygroscopicity. And the fabrics prepared by elastic fiber have good wearing comfort due to its elasticity. How to prepare an elastic imitation cotton and linen polyester fiber with good elasticity and imitation cotton and linen effect. Utility Model Content
[0003] In order to solve the above technical problems, the utility model provides an elastic cotton-like polyester fiber.
[0004] In order to solve the above technical problems, the purpose of the utility model is achieved as follows:
[0005] The utility model relates to an elastic imitation cotton and linen polyester fiber, comprising a core yarn, and super-imitation cotton polyester fibers and imitation linen slub yarns wound around the outside of the core yarn; the super-imitation cotton polyester fibers and imitation linen slub yarns are spirally wound around the outside of the core yarn in opposite directions; the core yarn comprises parallel-twisted spandex filaments and Sorona fiber yarns.
[0006] On the basis of the above scheme and as a preferred scheme of the above scheme: the super-cotton-like polyester fiber has a hollow microstructure, and the volume of the hollow part accounts for 30% to 40% of the total volume.
[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the core yarn 1 is further spirally wound with a linen-like polyester filament.
[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the linen-like polyester filaments include two high-twist polyester filaments and hot-melt filaments twisted in parallel with each other and having opposite twists, and the linen-like polyester filaments are also provided with a plurality of bonding points for fixing the high-twist polyester filaments and the hot-melt filaments.
[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the twist of the high-twist polyester filament is 1200-1600 T / m.
[0010] The utility model has the following beneficial effects: the elastic cotton-like polyester fiber of the utility model has good elasticity because the core yarn uses the twisted spandex filament and Sorona fiber yarn, and the elasticity of the core yarn is more reliable because the Sorona fiber also has elasticity. The ultra-cotton-like polyester fiber used makes the fiber hygroscopic and has a cotton-like effect. The linen-like slub yarn used makes the fiber have a linen-like effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 1 is a schematic diagram of the structure of the elastic linen-like polyester fiber involved in Example 1;
[0012] Figure 2 It is a schematic diagram of the structure of the elastic linen-like polyester fiber involved in the second embodiment.
[0013] The markings in the figure are as follows: 1-spandex filament; 2-Sorona fiber yarn; 3-super imitation cotton polyester fiber; 4-imitation linen slub yarn; 5-imitation linen polyester filament. DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0015] Embodiment 1
[0016] Combination Figure 1 , this embodiment is described in detail. This embodiment involves a stretch imitation cotton and linen polyester fiber, comprising a core yarn, and super-imitation cotton polyester fiber 3 and imitation linen slub yarn 4 wound around the outside of the core yarn; the super-imitation cotton polyester fiber 3 and imitation linen slub yarn 4 are spirally wound around the outside of the core yarn in opposite directions; the core yarn comprises a spandex filament 1 and a Sorona fiber yarn 2 twisted in parallel.
[0017] Further, the super-imitation cotton polyester fiber has a hollow microstructure, and the volume of the hollow part accounts for 30% to 40% of the total volume. The super-imitation cotton polyester fiber is a hollow structure, and there are many micropores distributed on the side wall. These hollow structures and micropores form capillaries, so that the sweat produced by the human body enters the capillaries in time and is discharged to the surface of the fabric. The volume of the hollow structure and micropores accounts for 30% to 40% of the total volume, so that the fabric has good air permeability and softness, and increases the cotton feel. The bamboo-like linen yarn 3 can make the surface of the fabric prepared by the fiber look like a linen effect.
[0018] The core yarn 1 has twisted spandex filaments 1 and Sorona fiber yarns 2, which ensure the elasticity of the elastic cotton, linen and polyester fibers, and still have good elasticity even after the spandex filaments are broken.
[0019] Embodiment 2
[0020] Combination Figure 2 The present embodiment is described in detail. The elastic cotton-like polyester fiber of the present embodiment is different from the first embodiment in that the core yarn is further spirally wound with a linen-like polyester filament 5.
[0021] Furthermore, the imitation linen polyester filaments include two high-twist polyester filaments and hot-melt filaments twisted in parallel with opposite twists, and the imitation linen polyester filaments are also provided with a plurality of bonding points for fixing the high-twist polyester filaments and the hot-melt filaments. The twist of the high-twist polyester filaments is 1200-1600 T / m, and is 1600 T / m in this embodiment. The bonding points are formed by melting the hot-melt filaments by hot pressing, so that the hot-melt filaments are bonded to the high-twist polyester filaments, so that the twist of the high-twist polyester filaments between the two bonding points can be maintained. And the high-twist polyester filaments with opposite twist directions make the prepared fabric have the effect of imitating linen.
[0022] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
