The flexible waterproof material mainly refers to the waterproof film material on the surface of the building, forming one or more layers of polymer or synthetic polymer material with certain deformation ability, which can be divided into two categories: “rolling waterproof” and “coating” waterproof” Nonwoven fabrics(China Geotextile Supplier) are mainly used for coiling flexible waterproof materials.

As the basic raw material for waterproofing membrane, asphalt is the first application of organic flexible waterproofing material. It is the most widely used, widely used and most waterproof material in the world. According to historical verification, no cost-effective products have been found yet. Especially in roofing and underground engineering, through modified asphalt rolling materials, self-adhesive rolling materials, composite waterproofing system, combined with puncture resistance, salt-resistant alkaline rolling materials, to achieve waterproof, blockage roots, salt and alkali erosion resistance And other comprehensive features.

Non woven fabric(Geotextile Fabric Vendor) is the skeleton material of modified asphalt waterproofing membrane, which gives the waterproof membrane excellent tensile properties and prolongs its service life. A typical asphalt-based waterproofing membrane is actually a non-woven reinforced composite material, the structure of which is a sandwich structure, the intermediate layer is a non-woven fabric, and the two layers are modified asphalt.

There are mainly three kinds of non woven fabrics(Highway Nonwovens Company) used as modified asphalt waterproofing membranes, namely polyester spunbond needle-punched nonwoven fabric, polyester staple fiber needle-punched nonwoven fabric and wet glass fiber mat. Although the cost of the glass fiber mat is low, the synthetic fiber non-woven fabric can impart better flexibility to the modified asphalt waterproofing membrane, adapt to thermal expansion and shrinkage performance, greatly reduce the possibility of water leakage, thereby prolonging the service life of the waterproof membrane.

Except for a small amount of non-quality modified asphalt waterproofing membrane, at least the same area of ​​non-woven fabric as the skeleton material is required for each square meter of modified asphalt waterproofing membrane. In order to meet market demand, modified asphalt waterproofing membranes are increasingly using polyester spunbonded nonwovens.
