ABSTRACT:
A yarn is made by carding short lengths of glass fibre and then spinning the carded fibres. Advantageously short lengths of support fibre are mixed in with the short lengths of glass fibre before carding. A reinforcing strand may be buried in the yarn during spinning or during a subsequent twisting step. The support fibre should preferably be flexible. The resulting yarn, or goods made therefrom, can be used in many applications to replace goods based on asbestos fibres or on continuous glass fibres.
