This is what the CE dictionary says, although not specifically for geotextiles. However, I think it will work.

Enkadrain is a three-dimensional composite which consists of a drainage layer sandwiched between two geotextile filters. The drainage layer is composed of tough, looped polyamide filaments which are fused together where they cross, forming an open structured material with a voids ratio of 95%. The geotextile filter layers are made of heat bonded polyester core/nylon sheath non-woven fabric, with a thickness of 0.7 mm.
