Process for manufacturing strings to be subjected to tensile stress, in particular strings for rackets and musical instruments, and strings obtained thereby

摘要

The process for manufacturing strings according to the invention is of the type comprising a step in which a thread is produced from fibres, a step in which the thread is impregnated with a resin, a step in which the impregnated thread is coated with a synthetic material to provide it with a sheath, a step in which the synthetic material is caused to be completely cross-linked, and a step in which the thickness of the sheath is adjusted. It is characterized by use of discontinuous fibres that are subjected to textile operations of intersecting and drawing-twisting. The process according to the invention makes it possible to produce strings designed to be subjected to tensile stress, in particular strings for rackets and musical instruments.
