ABSTRACT:
The present invention relates to a process for producing glass strands coated with a hot-melt size, whereby molten glass streams, flowing out of orifices located in the base of one or more bushings, are drawn in the form of one or more sheets of continuous filaments, the filaments are then assembled into one or more strands that are collected on one or more moving supports, this process consisting in depositing a first composition containing a coupling agent on the glass filaments and then in depositing a second composition comprising a hot-melt polymer in the melt state, at the latest during assembly of the filaments into one or more strands. It also relates to the glass strands obtained according to this process and to the composites containing said strands.
