摘要
Prodn. of two layer textile reinforcement for bituminous roof sealing coating consists of taking a non-woven layer and consolidating it by mechanical binding or hydraulic binding e.g. by water jet; then thermostabilising at 180-240, pref. 200-220 degrees C for 5-60, pref. 8-20 secs.. That layer is then assembled with a second mineral fibre, esp. glass fibre, layer by bonding, sewing or knitting. The last two methods are only used when the second layer is a fabric or a mesh. The adhesive for bonding is a thermoplastic or hot-set polymer e.g. polyester, polyamide, polyurethane or EVA, with m.pt. of 160-220 pref. 190-200 degrees C.
