Description

Technical Field

[0001] This invention relates to clothing, and more particularly to an environmentally friendly functional garment. Background Technology

[0002] Currently, most breathable and waterproof membranes used in commercially available clothing and shoes use oil-based solvent-based resins as their main raw material to achieve the required initial water pressure resistance and moisture permeability, as well as to maintain a certain degree of waterproofness after 5 to 10 washes. However, because these oil-based solvent-based resins contain a large amount of solvents, such as dimethylformamide (DMF), methyl ethyl ketone (MEK), toluene, and xylene, the production process of such breathable and waterproof membranes generates volatile organic compounds that are harmful to the environment.

[0003] With increasing public awareness of environmental protection and carbon emissions, many companies have switched to using environmentally friendly water-based resins that do not produce volatile organic compounds as materials for developing next-generation breathable and waterproof membranes. Among these, water-based polyurethane resin is the most common. However, the breathable and waterproof membranes currently on the market developed using water-based resins are not yet mature. In addition to the low initial water pressure resistance measured under the Japanese standard JIS L1092 (2020 edition) water resistance test method, which only reaches 3000-5000 mmH2O, after washing, the water pressure resistance drops to 1000 mmH2O, rendering it non-waterproof. Its waterproofness, breathability, and washability are all poor. Summary of the Invention

[0052] Therefore, the environmentally friendly functional garment 100 of this invention achieves an initial water resistance of 20,000 mmH2O under the Japanese standard JIS L1092 (2020 edition) water resistance test method, and 10,000 mmH2O under the low-pressure method ISO 811 (2018 edition) water resistance test method. Under the Japanese standard JIS L 1099A1 (2012 edition) moisture permeability test method, the moisture permeability reaches 3,000–10,000 g / m². 2 Under the Japanese standard JIS L1099B1 (2012 edition) test method for moisture permeability, the measured moisture permeability can reach 10,000 to 30,000 g / m³ over 24 hours. 2 Under the ASTM E96 B (2024a edition) standard test method for moisture permeability, the measured moisture permeability can reach 600-800 g / m³ over 24 hours. 2 Under the ASTM E96 BW (2024a edition) standard test method for moisture permeability, measured moisture permeability can reach 8000–15000 g / m³ over 24 hours. 2 / 24hr.

[0053] Thus, the dynamic waterproof test of the environmentally friendly functional garment 100 of the present invention can reach 15,000 to 50,000 cycles. Importantly, after 5 to 10 washes, the water resistance of the environmentally friendly functional garment 100 of the present invention can still reach 20,000 mmH2O under the waterproof test method of Japanese standard JIS L1092 (2020 edition) and 10,000 mmH2O under the low-pressure test method of ISO 811 (2018 edition). Moreover, the above-mentioned moisture permeability can be maintained within the same range after washing.

[0054] Based on the above description, the advantages of the present invention can be summarized as follows:

[0055] I. Compared with the prior art, the front breathable and waterproof inner layer 112 of the front panel 11 of each front panel unit 10, the rear breathable and waterproof inner layer 212 of the rear panel 21 of the rear panel unit 20, the sleeve breathable and waterproof inner layer 312 of the sleeve panel 31 of each sleeve panel unit 30, the neckline breathable and waterproof inner layer 412 of the neckline panel 41 of the neckline unit 40, and the pocket breathable and waterproof inner layer 712 of the pocket panel 71 of each pocket unit 70 are made of materials that do not contain solvent components and are environmentally friendly.

[0056] II. Compared with the prior art, the present invention, through the material combination design of the front breathable and waterproof inner layer 112 of the front cut piece 11 of each front piece unit 10, the rear breathable and waterproof inner layer 212 of the rear cut piece 21 of the rear piece unit 20, the sleeve breathable and waterproof inner layer 312 of the sleeve cut piece 31 of each sleeve unit 30, the neckline breathable and waterproof inner layer 412 of the neckline cut piece 41 of the neckline unit 40, and the pocket breathable and waterproof inner layer 712 of the pocket cut piece 71 of each pocket unit 70, especially the water-based foaming agent, can have good waterproof and breathable properties, and can still have excellent waterproof and breathable properties after washing, and has good washability.
