Description

Technical Field

[0001] The utility model relates to a moisture-conducting and breathable vortex-spun core-spun yarn, belonging to the technical field of vortex-spun core-spun yarn. Background Art

[0002] The requirement for clothing is to have good moisture conduction and breathability. The moisture conduction and breathability of the fabric can quickly guide the sweat secreted by the human body out, so that it can be quickly carried away by the airflow flowing outside the clothing, thereby achieving the moisture conduction effect. If the yarn used for woven fabrics has a moisture conduction and breathability effect, the prepared fabric will also have a moisture conduction and breathability effect. Vortex spinning is an improvement on the basis of jet spinning, and it is a spinning equipment suitable for spinning pure cotton. Compared with traditional ring spinning: it has the characteristics of short spinning process, high production efficiency, online quality monitoring, high degree of automation and intelligence, and also has the advantages of greatly reducing labor and reducing yarn hairiness. Therefore, vortex spinning yarn is processed into needle and cotton fabrics, which have many excellent properties. How to prepare a moisture-conducting and breathable vortex spinning core-spun yarn has become a problem to be solved. Utility Model Content

[0006] The fibers used in the first coating fiber layer are three-dimensional curled fibers; the fibers used in the second coating fiber layer are polyester fibers or polyamide fibers, and their cross-sections are cross-shaped, Y-shaped, I-shaped, triangular, straight-shaped or wavy.

[0007] On the basis of the above scheme and as a preferred scheme of the above scheme: the core yarn includes flax fiber yarns and polyester filaments twisted together.

[0008] On the basis of the above scheme and as a preferred scheme of the above scheme: the polyester fiber is polyester fiber or polylactic acid fiber.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: the polyamide fiber is nylon 6 fiber, nylon 66 fiber or bio-based nylon 56 fiber.

[0010] On the basis of the above scheme and as a preferred scheme of the above scheme: the three-dimensional curled fiber is a PET / PTT parallel bicomponent fiber or a PET / PBT parallel bicomponent fiber.

[0012] The beneficial effects of the utility model are as follows: the moisture-conducting and breathable vortex-spun core-spun yarn involved in the utility model has a first covering fiber layer using three-dimensional curled fibers, so that the first covering fiber layer has more gaps, thereby providing the yarn with a breathable effect.

[0016] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] Embodiment 1

[0018] Combination Figure 1 The present embodiment is described in detail. The moisture-conducting and breathable vortex-spun core-spun yarn involved in the present embodiment comprises a core yarn 1, a first covering fiber layer 2 and a second covering fiber layer 3; the first covering fiber layer 2 is covered on the outside of the core yarn 1, and the second covering fiber layer 3 is covered on the outside of the first covering fiber layer 2.

[0019] The fibers used in the first covering fiber layer 2 are three-dimensional curled fibers. Due to the three-dimensional curled structure of the three-dimensional curled fibers, there are more gaps inside the first covering fiber layer 2, so that the moisture-conducting and breathable vortex-spun core-spun yarn involved in this embodiment has a breathable effect.

[0020] Further, the three-dimensional crimped fiber is a PET / PTT parallel bicomponent fiber or a PET / PBT parallel bicomponent fiber. In this embodiment, the PET / PTT parallel bicomponent fiber is selected. In the PET / PTT parallel bicomponent fiber, the volume ratio of PET to PTT is 50:50, and when the single fiber linear density is about 6.67 dtex, the crimp index reaches 40%.

[0021] The fibers used in the second covering fiber layer 3 are polyester fibers or polyamide fibers, and their cross-sections are cross-shaped, Y-shaped, I-shaped, triangular, straight-shaped or wavy. Polyester fibers and polyamide fibers have low hygroscopicity, and the fibers with special-shaped cross-sections can make the second covering fiber layer 3 have a moisture-conducting effect through the wicking effect.

[0022] Further, the polyester fiber is polyester fiber or polylactic acid fiber. Polylactic acid fiber is polylactide, and polyester fiber is polyethylene terephthalate. In this embodiment, polyester fiber is selected, and its cross-sectional shape is selected to be a cross.

[0023] Further, the polyamide fiber is nylon 6 fiber, nylon 66 fiber or bio-based nylon 56 fiber. Polyamide fiber has good wear resistance, and can provide the moisture-conducting and breathable vortex-spun core-spun yarn with good wear resistance. In this embodiment, bio-based nylon 56 fiber is selected.

[0024] Furthermore, the core yarn 1 comprises flax fiber yarn and polyester filament twisted together. The flax fiber provides good stiffness for the moisture-conducting and breathable vortex-spun core yarn, and has the characteristics of good moisture absorption and fast moisture conduction. In this embodiment, the polyester filament can be selected as polylactic acid fiber filament.

[0025] The preparation process of the moisture-conducting and breathable vortex-spun core-spun yarn involved in this embodiment is as follows: the flax fiber yarn and the polyester filament twisted together are used as the core yarn 1, and the first covering fiber layer 2 is covered on the outside of the core yarn 1 by using the vortex core-spun yarn production process. The second covering fiber layer 3 is covered on the outside of the first covering fiber layer 2 by using the vortex core-spun yarn production process again.

[0026] Embodiment 2

[0027] Combination Figure 2 The moisture-conducting and breathable vortex-spun core-spun yarn of this embodiment is different from that of the first embodiment in that a covering silk layer 4 is provided between the first covering fiber layer 2 and the second covering fiber layer 3; the covering silk layer 4 is polypropylene filaments, and a nano zinc oxide antibacterial agent is attached to the surface of the polypropylene filaments. The polypropylene fiber can be considered to have zero moisture absorption, and the nano zinc oxide antibacterial agent attached to its surface can improve the antibacterial effect.

[0028] 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.
