Description

TECHNICAL FIELD

[0001] The utility model relates to the field of textile, more specifically, it relates to a copper ion bacteriostatic superfine yarn and fabric. BACKGROUND

[0002] Yarn is woven to form a fabric, and the fabric can form clothes, home textiles or other textile products through a series of processes such as cutting and sewing. Based on different use requirements, yarn and the fabric woven by yarn can present different effects through different materials, different structures and different processing methods. However, for clothes and home textile products that need to be in contact with users, moisture absorption and sweat release are a common requirement. However, when the yarn absorbs moisture, the fabric will remain in a moist state for a certain period of time, which can easily lead to bacterial growth. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a copper ion bacteriostatic superfine yarn and fabric.

[0004] The above technical purpose of the utility model is realized by the following technical scheme: a copper ion bacteriostatic superfine yarn, comprising a core and a wrapping yarn wrapped outside the core, a groove is arranged on the surface of the core, the wrapping yarn comprises a high-twist portion and a low-twist portion, the high-twist portion and the low-twist portion are arranged alternately along the axial direction of the yarn, and the surface of the core is made of a bacteriostatic material.

[0005] The utility model is further provided as follows: the core comprises a core yarn and a plurality of wrapping yarns wrapped outside the core yarn, and the groove is located between the wrapping yarns.

[0006] The utility model is further provided as follows: the twist direction of the wrapping yarn is opposite to the twist direction of the wrapping yarn.

[0007] The utility model is further provided as follows: the wrapping yarn is twisted from polyester superfine fiber filaments.

[0008] A fabric comprises copper ion bacteriostatic superfine yarn and elastic yarn, and the copper ion bacteriostatic superfine yarn and the elastic yarn are arranged alternately and spaced apart in the warp direction and the weft direction.

[0009] The utility model is further provided as follows: the elastic yarn is composed of polyester fiber bundles.

[0010] In summary, the utility model has the following beneficial effects: the wicking effect of the groove increases the moisture absorption and moisture transfer capacity of the yarn, thereby improving the moisture absorption and sweat release performance of the fabric woven from the yarn. The polyester superfine fiber filaments form smaller and more capillary pores, which greatly improve the moisture absorption of the yarn and the capillary wicking capacity of the yarn.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Example 1: A copper ion antibacterial ultrafine yarn, such as Figure 1 As shown, the yarn includes a core and a covering yarn 1 wound around the core. The surface of the core has grooves 2. The covering yarn 1 includes a high-twist section and a low-twist section, which are alternately arranged along the axial direction of the yarn. The surface of the core is made of antibacterial material. The core includes a core yarn 3 and several winding yarns 4 wound around the core yarn 3. The grooves 2 are located between the winding yarns 4. The winding yarns 4 are made of twisted polyester microfiber filaments.

[0016] Specifically, the yarn core consists of a single strand and three strands of winding yarn 4 wrapped around it. The three strands of winding yarn 4 are closely fitted together, and the groove 2 is located between the two outermost strands of winding yarn 4. The wicking effect of the groove 2 increases the moisture absorption and wicking capacity of the yarn, thereby improving the moisture-wicking performance of the fabric woven from the yarn. The diameter of the covering yarn 1 is larger than that of the winding yarn 4. The covering yarn 1 is made of polyester. In the high-twist section, the covering yarn 1 tightly binds the winding yarn 4, ensuring the structural stability of adjacent winding yarns 4, and thus ensuring the dimensional stability of the groove 2. In the low-twist section, the covering yarn 1 covers a smaller area of ​​the yarn core, allowing moisture to penetrate into the yarn core and pass through the core. The absorption effect is transmitted, increasing the effective moisture dissipation area of ​​the yarn, thereby improving the drying speed of the yarn and reducing the damp time of the fabric after moisture absorption. The polyester microfiber filaments form smaller and more numerous capillary pores, which not only greatly improves the moisture absorption of the yarn, but also greatly improves the capillary wicking capacity of the yarn. The surface of the polyester microfiber filaments is attached with copper ion masterbatch, which improves the antibacterial effect of the polyester microfiber filaments. When moisture is transferred through the groove 2, the copper ion masterbatch ensures the antibacterial properties of the yarn. At the same time, the low crimp modulus of the polyester microfiber filaments improves the softness of the final woven fabric.

[0017] The twist direction of the covering yarn 1 is opposite to that of the winding yarn 4, such as... Figure 1As shown, specifically, the wrapping yarn 1 is Z twist, the wrapping yarn 4 is S twist, and the opposite twist direction increases the friction between the wrapping yarn 4 and the wrapping yarn 1, thereby improving the connection strength between the wrapping yarn 4 and the wrapping yarn 1, that is, further ensuring the structural stability between the adjacent wrapping yarns 4.

[0018] Embodiment two: a fabric, such as Figure 2 As shown, comprising copper ion antibacterial superfine yarn 5 and elastic yarn 6, the copper ion antibacterial superfine yarn 5 and the elastic yarn 6 are alternately and spacedly arranged in the warp direction and in the weft direction, the elastic yarn 6 is composed of polyester fiber bundles, specifically, the copper ion antibacterial superfine yarn 5 and the elastic yarn 6 are formed into warp plain weave by the warp and weft weaving of the shuttle loom, in the warp yarn system, the copper ion antibacterial superfine yarn 5 and the elastic yarn 6 are alternately and spacedly arranged, in the weft yarn system, the copper ion antibacterial superfine yarn 5 and the elastic yarn 6 are also alternately and spacedly arranged, ensuring that both sides of any elastic yarn 6 are in contact with the copper ion antibacterial superfine yarn 5, ensuring the antibacterial effect of the whole fabric, the elastic yarn 6 is twisted from several polyester fiber bundles, the polyester fiber bundles have good deformation performance, ensuring the softness of the fabric.

[0019] The preferred embodiments of the present application are described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solution falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application, these improvements and decorations should also be considered as the protection scope of the present application.
