Abstract
The invention relates to a novel binder system and its use for bonding textile fabrics as well as products containing such bonded textile fabrics. The materials according to the invention are suitable for manufacturing base interlinings which may be used for manufacturing base interlinings for sarking, roofing and sealing membranes, particularly for manufacturing coated sarking, roofing and sealing membranes.
Claims27
A method of making an article, the method comprising:
- melting at least one polymer to form a melted polymer;
- passing the melted polymer through spinneret rows to form spun polymer streams;
- stretching the spun polymer streams to form a plurality of fibers;
- forming the plurality of fibers into a spunbond textile fabric;
- applying a binder system to the spunbond textile fabric,
- wherein the binder system comprises an aqueous dispersion comprising:
- at least one emulsion polymer and
- at least one starch;
- wherein the binder system has a viscosity of between 10 and 2200 mPa*s in accordance with DIN EN ISO 3219 at 23° C.;
- and
- solidifying the binder system into a binder that is incorporated into the spunbond textile fabric.
