What are the characteristics and functions of the non-woven fabric used on the waterproof and breathable membrane of the isolation layer?

Waterproof and breathable membrane is a new type of polymer waterproof material. In terms of production technology, the technical requirements of waterproof and breathable membranes are much higher than those of general waterproof materials; at the same time, from the perspective of quality, waterproof and breathable membranes also have functional characteristics that other waterproof materials do not have. The non-woven fabric as an isolation layer waterproof and breathable membrane has the following product characteristics and functions. You can see: 1. First of all, the non-woven fabric has strong anti-ultraviolet and anti-aging functions. The air barrier film is waterproof, moisture-proof, anti-soaking, and prevents water vapor from passing through. Generally, the steel structure (or wood structure) roof or the wall surface is matched with a waterproof and breathable membrane. It is laid under the insulation cotton, and then the moisture of the insulation cotton is blocked to penetrate into the building, and the interior is kept dry. The vapor barrier of the product is based on polymer materials with a coating on it to make the materials have good waterproof function and airtightness. Even after three months of outdoor exposure in summer, it still insists on outstanding product functions. 2. The non-woven fabric has good resistance to pulling, tearing and high abrasion resistance. And it's relatively soft. 3. An important feature of non-woven fabrics is that they have excellent thermal insulation and can block the entry of external cold air. Through the outstanding ventilation function of the waterproof and breathable membrane, the water vapor can be discharged quickly, and then the effect of the insulation layer can be ensured to achieve the effect of continuing to save energy. It can also effectively prevent water vapor from entering the insulation layer and form a comprehensive maintenance of the insulation layer. The formation of condensation. Use with other insulation materials. 4. Non-woven fabrics can also improve the comfort of living very effectively. Greatly improve the comfort of the living environment, and therefore enhance the durability of the building. So that the water vapor can be quickly discharged, reduce indoor humidity, and effectively prevent mold and condensation. Has excellent ventilation function. 5. The water-repellent non-woven fabric also has good water-repellent properties, which can effectively isolate the indoor invasion of wind and rain.
