terylene
A generic name for a synthetic thread which has
the advantages of nylon thread, but does not have
the undesirable high degree of elasticity. Because
of its lower elasticity, it does not present the
problem of thread retraction after cutting. As
with nylon thread, it is highly resistant to
moisture and retains a large part of its dry
strength when wet. Terylene is also almost
entirely free from contaminating metals which
might tend to cause degradation. It is also used
in sheet form in the repair of documents and the
leaves of books. (81
