ABSTRACT:
Method to make elastic knitwear fabric from an elastic or elastomeric thread (11a) and from at least one non elastic thread (11b), the method using a single-section run-proof knitting machine, or Raschel type machine, having a bar of needles (12) moving in alternation and at least a forward bar and a rear bar of guide needles onto which the relative threads which have to be knitted are threaded, the elastic thread (11a) being constituted by an elastic thread known commercially by the name of LYCRA thread, or material similar or comparable to it, with a count between 22 and 80 Dtex; the non elastic thread (11b) being constituted by a multi-filament nylon thread, or material similar or comparable to it, with a count of between 22 and 78 Dtex, where the ratio between the count expressed in Dtex and the filament count is the same or less than two; the knit of the non elastic thread (11b) having a basic pattern with a recurrence equal to four rows (13) of the machine, in which at least three consecutive rows (13) work on separate needles (12). Elastic knitwear fabric obtained by the method described above, using an elastic thread (11a) identifiable as LYCRA thread with a count of 40 Dtex and a multi-filament non elastic thread (11b) with a count of 44 Dtex and 28 filaments, with a maximum thickness of around 0.54 mm and a minimum thickness of around 0.30 mm according to the type of basic knit used.
