2049307 9111549 PCTABS00006 A string (10) for a sports racquet, such as a tennis racquet string, is comprised of a string core (20) having a plurality of external ridges (40) bonded thereon for aiding in imparting spin on a ball and for increasing the cross-over contact area between strings. The ridges are parallel to one another and extend axially with the string. Preferably, the string and ridges can be circumscribed by a maximum diameter circle (90), preferably of 1.70 millimeters. The process for making the ridged string includes passing a string core (20) through a bath (72) of resin (71), such as nylon, for coating and glueing the core and then through a die (74) shaped so as to form the ridges (40).
