Description

Technical Field

[0001] This utility model belongs to the field of functional clothing, specifically relating to a moisture-wicking and cooling garment. Background Technology

[0002] As a type of personal protective equipment, protective clothing effectively blocks threatening substances such as toxic industrial chemicals, biological viruses, or bacteria in high-risk environments, thereby protecting the health and safety of workers. Therefore, it is widely used in critical fields such as medical, military, firefighting, and petrochemical industries. Protective clothing typically has a dense structure, providing excellent protective performance, but generally suffers from poor moisture permeability. This causes the wearer to accumulate heat and moisture during work, leading to physiological discomfort such as heat stress and affecting work efficiency. Traditional strategies for addressing heat stress mainly involve improving the thermal and moisture comfort of the wearer inside the protective clothing through active or passive cooling methods. Active cooling methods, such as liquid cooling, air cooling, or semiconductor refrigeration, have drawbacks such as high cost, the need for additional power supply systems, and large garment volume, limiting their application in special scenarios. Passive cooling methods, on the other hand, rely on the intrinsic properties of materials and environmental conditions to improve thermal comfort and reduce heat accumulation through non-energy-consuming methods. They offer advantages such as low cost, ease of processing, and lightweight design, such as passive cooling clothing.

[0003] Patent CY 2726340Y discloses a temperature-regulating garment with numerous regularly shaped spaces sewn into the inner side. These spaces are filled with multiple phase-change capsules, which can be used for bidirectional temperature regulation. Patent CN 208446639 discloses a composite cooling garment with pockets on the outer surface for holding cooling blocks. These blocks consist of a non-woven fabric-wrapped polyglutamic-polylysine hydrogel functional layer and a paraffin phase-change material layer. Water is pre-stored in the cooling blocks and transferred to the hydrogel functional layer, which then evaporates the water to achieve cooling. Currently, most passive cooling garments typically only consider a single cooling method and do not address the issue of excessive humidity inside the garment when the wearer is working. The inability to evaporate or absorb sweat in time leads to extremely high humidity inside the garment, exacerbating heat stress and severely affecting the wearer's physiological comfort. Therefore, developing new types of clothing with both moisture-wicking and cooling functions to improve the thermal and moisture comfort of personnel wearing protective clothing, reduce heat stress response, and thus improve work efficiency and protect human health has become an urgent problem to be solved. Summary of the Invention

[0004] (a) Technical problems to be solved

[0025] A type of moisture-wicking and cooling clothing, such as Figure 1 As shown, the garment includes a main body 1, a cooling pack 2, and a moisture-absorbing material 3. The main body of the garment consists of a functional fabric 4, a cooling coating 5, a mesh pocket 6, and a zipper 7, arranged from the outside to the inside. The cooling pack 2 and the moisture-absorbing material 3 can be filled into the mesh pocket respectively.

[0026] Furthermore, the functional fabric is a cooling fabric with a contact cooling coefficient of not less than 1.5 J / (cm2·s), and has thermal and moisture-wicking functions.

[0027] Furthermore, the zipper structure is an open-end zipper.

[0028] Furthermore, the cooling coating is a phase change microcapsule coating with a cooling effect, wherein the microcapsule shell material is a melamine-formaldehyde polymer and the core material is n-octadecane.

[0029] Furthermore, the cooling coating is located inside the garment, and the process is a coating method.

[0030] Furthermore, the mesh pockets are made of breathable mesh gauze, and are rectangular in shape. Their size and number can be adjusted as needed. The pockets are located on the front chest, the inner side of the abdomen and the inner side of the back of the garment, as well as on both sides of the armpits and waist inside the garment.

[0031] Furthermore, the cooling pack is rectangular, such as... Figure 2 As shown, it matches the size of the web pocket and includes breathable mesh gauze and a phase change capsule, wherein the phase change capsule has a diameter of 2mm, the capsule shell material is melamine-formaldehyde polymer, and the core material is n-octadecane.

[0032] Furthermore, the moisture-absorbing material is a polyacrylamide / lithium chloride composite hydrogel membrane with moisture-absorbing function, and the membrane thickness is 2 mm.

[0033] The moisture-wicking and cooling garment was used in a dummy testing system to test its cooling effect. The control group consisted of dummy wearing only protective clothing, while the experimental group consisted of dummy wearing the moisture-wicking and cooling garment inside and protective clothing outside. The test conditions were moderate sweating mode and high sweating mode, and the changes in humidity and temperature inside the garment were tested. The results are shown in Tables 1 and 2. As shown in Tables 1 and 2, under moderate sweating conditions, the experimental group wearing the moisture-wicking and cooling garment had a final temperature 0.5℃ lower than the control group after 10 minutes of testing. The humidity inside the garment in the experimental group decreased to 53.3%RH after 60 minutes, significantly lower than the 90.1%RH of the control group. Under heavy sweating conditions, the experimental group wearing the moisture-wicking and cooling garment had a final temperature 0.5℃ lower than the control group after 8 minutes of testing. However, the humidity inside the garment in the experimental group decreased to 65.1%RH after 60 minutes, significantly lower than the 96.2%RH of the control group. This demonstrates that the moisture-wicking and cooling garment exhibits excellent cooling and moisture-wicking functions under both testing conditions, especially with a significant reduction in humidity. Therefore, this moisture-wicking and cooling garment can be used to improve human physiological comfort and will have excellent applications in the field of thermal management for clothing.
