Description

Technical Field

[0001] This utility model relates to the field of textile fabric technology, specifically to a moisture-absorbing and heat-generating polyester fabric. Background Technology

[0002] As people's demands for clothing functionality continue to increase, heat-generating fabrics are widely used in outdoor clothing, thermal underwear, and loungewear due to their ability to provide extra heat and improve comfort in cold environments. Polyester fabric, with its high strength, good abrasion resistance, excellent dimensional stability, and relatively low production cost, has become one of the commonly used base materials for heat-generating fabrics. Far-infrared heat-generating polyester fabric is currently the mainstream product on the market. The heating principle of far-infrared heat-generating polyester fabric mainly involves adding far-infrared heat-generating powder during the preparation of polyester fibers. This powder absorbs infrared rays from the environment and the heat emitted by the human body, converting it into far-infrared radiation energy that is fed back to the body, thus achieving a passive heating effect. However, existing far-infrared heating polyester fabrics have obvious technical shortcomings in practical applications: On the one hand, polyester fiber itself is a hydrophobic fiber, and its molecular structure lacks hydrophilic groups, resulting in poor moisture absorption of the fabric. When worn, it is difficult to quickly absorb the sweat secreted by the human body, and it is easy to form a damp layer on the skin surface. This not only affects the dryness of the skin-to-skin feel, but may also cause stuffiness and stickiness due to sweat retention, reducing the comfort of wearing the fabric. On the other hand, the addition of far-infrared heating powder often further aggravates the roughness of the fabric, making the skin-to-skin feel unpleasant, especially in the application of close-fitting clothing, where this problem is more prominent.

[0003] To address the aforementioned problem of insufficient moisture absorption, existing technologies typically employ the method of incorporating moisture-absorbing fibers into polyester fabrics. Moisture-absorbing fibers can quickly absorb and conduct sweat, thereby improving the overall moisture absorption performance of the fabric. While moisture-absorbing fibers enhance the fabric's moisture absorption capacity, they also lead to a significant decrease in the fabric's strength and elongation at break after moisture absorption, affecting its durability, wrinkle resistance, and dimensional stability. Therefore, this invention provides a moisture-absorbing and heat-generating polyester fabric. Utility Model Content

[0004] The purpose of this invention is to provide a moisture-absorbing and heat-generating polyester fabric.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: A moisture-absorbing and heat-generating polyester fabric includes: an upper layer and a lower layer, wherein the lower layer is disposed on one side of the upper layer; The upper layer is woven from a first moisture-absorbing and heat-generating composite yarn, which includes a core filament and a wrapping filament spirally wound around the core filament.

[0019] Example 1: like Figure 1 As shown, a moisture-absorbing and heat-generating polyester fabric includes: an upper layer 1 and a lower layer 2, wherein the lower layer 2 is disposed on one side of the upper layer 1; The upper layer 1 is woven from the first moisture-absorbing and heat-generating composite yarn, such as... Figure 2 As shown, the first moisture-absorbing and heat-generating composite yarn includes a core filament and a wrapping filament spirally wound around the core filament. The core filament is spandex filament 11, and the wrapping filament includes far-infrared polyester filament 12 and ramie fiber yarn 13 spirally wound around the spandex filament 11 in a 1:1 ratio. The spandex filament 11 gives the upper layer 1 high elasticity, the far-infrared polyester filament 12 gives the upper layer 1 high strength and far-infrared heat-generating capacity, and the ramie fiber yarn 13 improves the moisture absorption capacity of the upper layer 1 while also ensuring the strength of the upper layer 1 after moisture absorption.

[0020] The lower layer 2 is woven from a second moisture-absorbing and heat-generating composite yarn, such as... Figure 3As shown, the second moisture-absorbing and heat-generating composite yarn includes a core filament and a wrapping filament spirally wound around the core filament. The core filament is spandex filament 11, and the wrapping filament includes far-infrared polyester filament 12 and Lyocell fiber yarn 14 spirally wound around the spandex filament 11 in a 1:1 ratio.

Figure 5 and Figure 6 As shown, the first moisture-absorbing and heat-generating composite yarn also includes vinylon fiber yarn 15, which is arranged in a 1:1:1 ratio with far-infrared polyester filament 12 and ramie fiber yarn 13; the second moisture-absorbing and heat-generating composite yarn also includes vinylon fiber yarn 15, which is arranged in a 1:1:1 ratio with far-infrared polyester filament 12 and Lyocell fiber yarn 14.

[0023] Vinylon fiber not only has high moisture absorption capacity but also high strength. When compounded into fabrics, it can not only improve the fabric's moisture absorption capacity but also increase its strength, ensuring that the fabric retains high strength even after absorbing moisture.

[0024] Example 3: like Figure 4 As shown, in this embodiment, based on Embodiment 1 or Embodiment 2, an outer layer 3 is provided on the side of the upper layer 1 away from the lower layer 2.
