How is the waterproof function of the boy's coat achieved?
Publish Time: 2024-11-28
The waterproof function of the boy's coat is mainly achieved through the following methods and technologies to ensure that the clothes are kept dry and comfortable in rainy or humid environments.1. Waterproof coatingPolyurethane (PU) coating: Polyurethane coating is a common waterproof coating material with good waterproof performance and wear resistance. By applying a thin layer of polyurethane on the surface of the fabric, a waterproof barrier is formed to prevent moisture from penetrating.Fluorocarbon coating: Fluorocarbon coatings (such as Teflon) have super strong waterproof performance and chemical corrosion resistance. Fluorocarbon compounds are applied to the surface of the fabric to make the fabric hydrophobic, and water droplets will quickly roll off after contacting the fabric without penetrating into the interior.Silicone coating: Silicone coating has excellent waterproof performance and softness, and is suitable for clothing that requires a soft touch. Silicone coating can form a waterproof film on the surface of the fabric, effectively preventing moisture from penetrating.2. Waterproof and breathable membraneePTFE membrane (such as Gore-Tex): ePTFE (expanded polytetrafluoroethylene) membrane is a high-tech waterproof and breathable material that achieves dual functions of waterproof and breathable through a microporous structure. The size of the micropores is smaller than a water droplet but larger than a water vapor molecule, making it impossible for moisture to pass through, but allowing water vapor to escape, keeping the interior dry and comfortable.PU coated breathable membrane: Combining polyurethane coating and microporous structure, the PU coated breathable membrane can provide excellent waterproof performance and achieve breathability, suitable for high-intensity sports and outdoor activities.3. Waterproof fabricNylon and polyester fibers: Nylon and polyester fibers have good waterproof properties and can form a waterproof barrier by tightly weaving. The high-density fabric structure can effectively prevent moisture penetration and is suitable for light waterproof needs.Coated fabric: A waterproof coating such as polyurethane, fluorocarbon or silicone is applied to the surface of the fabric to further enhance the waterproof performance. Coated fabric combines the durability of the fabric with the waterproofness of the coating and is suitable for a variety of application scenarios.4. Stitching and seam treatmentSeam sealing: Seams are the most likely part of clothing to seep water. Waterproof coats usually use seam sealing technology, such as heat sealing, taping or seam sealing, to prevent moisture from seeping in through the seams.Waterproof zipper: Waterproof coats are usually equipped with waterproof zippers to ensure that the zipper part will not seep water. Waterproof zippers maintain the waterproof performance of the zipper through special designs, such as double-layer teeth, waterproof coatings or waterproof sealing strips.5. Design and structural optimizationBrim and hem design: Waterproof coats are usually designed with extended brims and hems to increase the rain shelter area and prevent rain from dripping into the collar and hem.Cuff and collar design: Cuffs and collars are usually made of elastic materials or adjustable designs, which fit closely to the skin and prevent rain from seeping in from the cuffs and collars.Ventilation hole design: Without affecting the waterproof performance, waterproof coats are usually designed with ventilation holes or vents to help discharge internal moisture and maintain comfort.6. Finishing processWaterproof finishing: Some fabrics are treated with finishing processes such as impregnation, spraying or soaking to form a waterproof layer on the surface of the fabric. The finishing process can give ordinary fabrics a certain waterproof performance, which is suitable for medium and low waterproof needs.The waterproof function of the boy's coat is achieved through a variety of methods and technologies to ensure that the clothes are kept dry and comfortable in rainy or humid environments. The comprehensive application of technologies such as waterproof coating, waterproof breathable membrane, waterproof fabric, splicing and seam treatment, design and structure optimization, and finishing process provides a comprehensive and effective waterproof solution.
