METHOD FOR PRODUCING STRUCTURAL SYNTHETIC FIBBERS FOR CONCRETE AND MORTAR, AND SYNTHETIC FIBRE PRODUCED

Номер: CA0002919310C

Method for manufacturing structural synthetic fibers for concretes and mortars and the synthetic fiber obtained, particularly a polyolefin-based synthetic fiber for use in concretes and mortars with a hydraulic binder as a cementing base for increasing the elastic modulus of the same which comprises the mixture of polyolefin and additives, the formation of threads, a first stretching process, an alternate series of heating-cooling, collecting the threads in coils and stabilization of the polymerization/cross-linking for two days to one week; the threads are subsequently again subjected to one or several re-stretching phases, including the heating-cooling and subsequent stabilization processes if successive re-stretching processes are going to be carried out; lastly a surface etching phase and the cutting of the threads.

The invention relates to a method for producing structural synthetic fibres for concrete and mortar, and to the synthetic fibre produced, especially a polyolefin-based synthetic fibre, for using in concrete and mortar with a hydraulic binder as a cementing base, for increasing the modulus of elasticity thereof, comprising mixing polyolefin and additives, thread formation, a first stretching process, an alternative heating-cooling series, the collection of the threads into coils and the stabilisation of the polymerisation/cross-linking for two days to a week; the threads are subsequently subjected to at least one restretching phase, including the heating-cooling processes and subsequent stabilisation if successive restretching processes are to be carried out; and lastly there is a phase of surface etching and thread-cutting.
