PROCESS FOR PRODUCING THREADS OF GLASS FIBERS PROVIDED WITH PREPARATION AGENT, THE THREAD AND COMPOSITE

摘要

The invention concerns a method whereby fine metal threads are drawn in the form of continuous filaments from die(s), then joined into yarn(s) which are gathered, the method consisting in depositing a first stable composition, having a viscosity between 0.5 and 250 cP, on the filaments, in depositing a second stable composition brought separately, having a viscosity between 0.5 and 300 cP, on the filaments or yarns, at the earliest when the first composition is deposited and at the latest when they are gathered, the difference of viscosity between the compositions being less than 150 cP, the mixture of compositions having further, the functions of sizing and polymerising at room temperature.
