Description

Technical Field

[0001] This utility model relates to an antibacterial and cooling knitted fabric, belonging to the field of knitted fabric technology. Background Technology

[0002] With society's increasing pursuit of quality of life and comfort in clothing, the integration of functionality and fashion in textiles has become an important direction for the development of textile technology. Against this backdrop, cooling and antibacterial technology has gradually attracted widespread attention in the textile industry. Antibacterial and cooling fabrics, as innovative products that meet consumers' needs for health and comfort, have gradually become a research hotspot in textile technology. Especially in hot climates and high-temperature environments, how to provide fabrics that possess both antibacterial properties and a cooling effect has become a pressing problem for the market. At the same time, due to the growing demand for comfortable and diverse clothing, the poor durability of traditional functional textiles has become a bottleneck that urgently needs to be overcome. If the fabric has a cooling sensation upon contact with human skin, it will improve wearing comfort.

[0003] Furthermore, people sweat profusely in hot weather, and sweat residue in fabrics can easily breed bacteria. In environments with strong sunlight, fabrics also need to have UV protection. The challenge lies in ensuring that the fabric provides a cooling sensation while also offering antibacterial and UV-protective properties. Utility Model Content

[0004] The purpose of this invention is to provide an antibacterial and cooling knitted fabric that has a cooling sensation upon contact, as well as antibacterial and UV protection effects.

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0006] This utility model relates to an antibacterial and cooling knitted fabric, comprising an outer layer and an inner layer woven on a double-sided circular knitting machine using a double-sided weave structure.

[0007] The inner layer is made of antibacterial and cooling composite yarn woven with a mesh structure; the outer layer is made of UV-resistant and moisture-wicking composite yarn woven with a plain weft knit structure.

[0008] The antibacterial cooling composite yarn is a serofil yarn formed by cooling fiber strips and antibacterial filaments; the yarn used for the cooling fiber strips is a cooling, sweat-wicking, quick-drying core-sheath type fiber.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: the antibacterial filament is antibacterial nylon 6 filament or antibacterial polyester filament.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the UV-protective and moisture-absorbing composite yarn includes a Sirofil yarn formed from moisture-absorbing fiber strips and UV-protective filaments.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the moisture-absorbing fiber strip is made of mugwort fiber or aloe vera fiber; the UV-protective filament is made of UV-protective nylon 6 filament or UV-protective polyester filament.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the outer layer is coated with a waterproof and breathable membrane on the side away from the inner layer.

[0013] The beneficial effects of this utility model are as follows: The antibacterial and cooling knitted fabric involved in this utility model has a cooling sensation due to the cooling, sweat-wicking, and quick-drying core-type fiber used in the inner layer, and the antibacterial filaments give the fabric an antibacterial effect. The UV-protective and moisture-wicking composite yarn used in the outer layer provides the knitted fabric with UV protection and moisture-wicking effects, thereby absorbing the sweat from the inner layer and keeping the inner layer dry. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of the antibacterial cooling knitted fabric involved in Example 1;

[0015] Figure 2 This is a schematic diagram of the structure of the antibacterial cooling knitted fabric involved in Example 2. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] Example 1

[0018] Combination Figure 1 This embodiment provides a detailed description. The antibacterial cooling knitted fabric involved in this embodiment includes an outer layer 1 and an inner layer 2 woven on a double-sided circular knitting machine using a double-sided weave. The inner layer 2 is woven from antibacterial cooling composite yarn using a mesh weave; the outer layer 1 is woven from UV-resistant and moisture-wicking composite yarn using a plain weave weft weave.

[0019] The inner layer 2 uses a mesh weave, while the outer layer 1 is woven with a plain weave, creating a single layer of fabric in the mesh area of ​​the inner layer, which improves the breathability of the fabric. Furthermore, the outer layer 1 in the mesh area provides UV protection, preventing skin damage at the mesh level. The mesh weave also reduces the surface area of ​​the inner layer 2 in contact with the body, preventing it from sticking to the skin after absorbing moisture, thus improving wearing comfort.

[0020] The antibacterial cooling composite yarn is a Sirofil-spun yarn formed from cooling fiber strips and antibacterial filaments; Sirofil spinning is a process of combining and twisting fiber strips and filaments into yarn. The yarn used in the cooling fiber strips is a cooling, sweat-wicking, quick-drying core-sheath type fiber. This sweat-wicking, quick-drying core-sheath type biomimetic fiber is a short fiber spun from a sheath and core layer in a 50:50 mass ratio. The core layer is composed of polyester, and the sheath layer is mainly composed of polyethylene with good thermal conductivity and a cooling sensation, along with hydrophilic masterbatch. This functional fiber resembles the structure of a tree's sheath and core; the sheath layer, like tree bark, absorbs moisture and wicks away sweat; the core layer, like the tree core, improves physical and mechanical properties, and does not absorb, retain, or store sweat, ensuring the fiber dries quickly. The hydrophilic sheath layer ensures the fabric quickly absorbs and wicks away sweat, but the hydrophilicity is limited to the sheath layer, effectively controlling the fiber's water retention; the core layer does not absorb or retain water, thus achieving a quick-drying effect. Conversely, if the core layer absorbs water, the increased water absorption requires more time to vaporize, thus prolonging the drying time and failing to achieve the desired quick-drying effect.

[0021] Furthermore, the antibacterial filament is either antibacterial nylon 6 filament or antibacterial polyester filament. In this embodiment, antibacterial nylon 6 filament is selected.

[0022] Furthermore, the UV-protective moisture-wicking composite yarn comprises a Sirofil yarn formed from moisture-wicking fiber strips and UV-protective filaments. The moisture-wicking fiber strips are made of artemisia fiber or aloe vera fiber; the UV-protective filaments are UV-protective nylon 6 filaments or UV-protective polyester filaments. In this embodiment, the moisture-wicking fiber strip is selected as artemisia fiber, which is made by adding artemisia extract to viscose fiber. Artemisia fiber contains natural antibacterial components of artemisia, is not a chemical additive, has no side effects on the human body, and is a fiber with good antibacterial properties.

[0023] The knitted fabric involved in this utility model has a cooling value of 0.28 W / cm² for the inner layer 2. -2 The requirement for cooling fabrics is greater than 0.15 W / cm². -2 .

[0024] Example 2

[0025] Combination Figure 2 This embodiment will be described in detail below. The antibacterial, cooling knitted fabric involved in this embodiment differs from that in Embodiment 1 in that: a waterproof and breathable membrane 3 is laminated to the side of the outer layer 1 away from the inner layer 2. This membrane is a non-porous breathable membrane or a microporous membrane.

[0026] Waterproof and breathable membranes can be classified according to their permeability principle and waterproof mechanism, mainly into two categories: non-porous breathable membranes and microporous membranes. Non-porous breathable membranes are typically made of hydrophilic polymers, and their internal structure contains hard and soft segments. The soft segments are rich in hydrophilic groups, which can efficiently absorb moisture emitted by the human body and quickly transfer moisture from the inside to the outside through an "adsorption-diffusion-desorption" process. The hard segments, on the other hand, are composed of hydrophobic groups, which can effectively block water droplets from passing through, thus achieving waterproofing. Furthermore, the permeability of non-porous breathable membranes is also affected by multiple factors such as the ratio of soft to hard segments, processing technology, and membrane thickness.

[0027] Currently, films employing a non-porous, moisture-permeable mechanism, especially thermoplastic elastomers (TPEs), occupy a significant market share. TPE films not only possess excellent flexibility, elasticity, and tensile properties, but also exhibit outstanding hydrostatic pressure resistance, while maintaining low production costs, giving them a significant market advantage. However, the moisture permeability of TPE films is affected by their thickness and the content of hydrophilic segments; the thinner the film and the higher the content of hydrophilic segments, the better its moisture permeability.

[0028] In this embodiment, a non-porous moisture-permeable membrane is selected, which is a TPE non-porous hydrophilic membrane.

[0029] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
