Manufacturing technology
Bicomponent melt spinning is suitable for thermoplastic polymers that can be processed below 400 °C, including PA11, PA12, RPA6, PC, PEI, TPE, PPS, and PEEK, among others.
These polymers are extruded as monofilament or multifilament, depending on the application requirements. The extrusion is carried out through multiple spinnerets, enabling the production of filaments with a homogeneous structure and precise diameter control. A post-extrusion longitudinal drawing of up to 500 % aligns the molecular chains, imparting high mechanical properties to the filaments — such as longitudinal stiffness, tensile strength, and abrasion resistance.
RACKET STRINGS
It is using this same process that we manufacture tennis and squash racket strings, both monofilament and multifilament, notably for brands such as Tecnifibre and Wilson.
