Whether Embossed Non-woven Fabric can maintain good performance and appearance when waterproofing is required depends mainly on the following factors:
1. Raw materials and waterproofing treatment of non-woven fabrics
Waterproof performance: The waterproof performance of embossed non-woven fabrics depends on the raw materials used and whether they are waterproofed. Generally speaking, ordinary non-woven fabrics may not have strong waterproof properties, but by adding waterproof coatings (such as polyurethane, PVC coatings) or using non-woven raw materials with good waterproof properties (such as special fibers), their waterproof properties can be significantly improved.
Affecting appearance: Waterproofing usually changes the surface texture of non-woven fabrics, which may make them smoother or slightly stiffer, especially in the embossed part. If not handled properly, it may affect the three-dimensional sense and touch of the embossed texture, resulting in some changes in appearance.
2. The impact of embossing process on waterproofness
Affecting water penetration: The embossing process itself may produce certain concave and convex structures on the surface of non-woven fabrics. These patterns and textures may affect the flow of water droplets, but usually do not completely prevent water penetration. Therefore, without a special waterproofing treatment, moisture may still penetrate into the fabric in the embossed area, especially in high humidity environments or prolonged exposure to water.
Maintaining waterproofness: In order to ensure waterproofness while maintaining the embossing effect, some manufacturers will continue to treat the non-woven fabric with a waterproof coating after embossing, or use a higher density fiber structure in the embossed part to reduce moisture penetration.
3. Usage scenarios and durability
Applicable scenarios: If it is used in contact with water or a humid environment for a short period of time, the embossed non-woven fabric can maintain its performance and appearance to a certain extent after waterproofing. For example, when used as some home decorations, lightweight packaging or disposable products, it is ideal to maintain waterproofness and appearance.
Long-term durability: In applications that require long-term exposure to water or humid environments (such as outdoor products, rain gear, etc.), the waterproofness and appearance of embossed non-woven fabrics may be affected over time. Moisture may penetrate into the fabric, especially after repeated use and washing, and the effect of the embossed texture and waterproof coating may gradually weaken.
4. Care and maintenance
Maintenance of water resistance and appearance: In order to maintain the water resistance and appearance of embossed non-woven fabrics, regular cleaning and maintenance are very important. Avoiding strong chemical cleaners and choosing appropriate cleaning methods (such as hand washing or low-temperature washing) can help extend its service life. At the same time, check the integrity of the waterproof coating and re-coat it if necessary to maintain its waterproof function.
After proper waterproof treatment, embossed non-woven fabrics can maintain good performance and appearance when waterproofing is required. However, the durability of waterproof performance and the stability of appearance depend on the selection of materials, production process and subsequent maintenance. If used in products exposed to water environments for a long time, it may be necessary to regularly maintain or re-treat the waterproof layer to ensure the functionality and aesthetics of the fabric.
