A cord, thread or filament is treated by applying to it a dilute solution of a polysiloxane prepolymer which is then cured, such that either (a) as in Figure 4 the outer envelope of the cord, thread or filament (20) is enrobed (19), or (b) in the case of a cord or thread, as seen in Figure 3, the filaments (14) thereof are substantially individually encapsulated by, a coating (17) of cured polysiloxane polymer. The treated cords, threads and filaments (15, 18) have inter alia improved abrasion and fray resistance, water repellance and slip qualities. |
