Laser fusion to impart cohesion to textured filament yarns
journal contribution

positioned in the path of the yarn being textured; to create knot-like intermittent
entangled nodes (‘nips’ or ‘tacks’) in the textured thermoplastic continuous multifilament
yarn.
This paper reports a proof-of-concept research into the use of a pulse laser to fuse
such yarns at discrete points at regular intervals along its length to impart cohesion
at required frequencies. Pulse frequency and duration, hence the heat intensity, are
varied to determine a suitable range of operating conditions. Results from a range of
polyester and nylon yarns show that fusing textured filament yarn to create nips is
feasible using a pulse laser as an alternative to intermingling by air jets.
The multifilament yarn is also modeled to compute the heat flow in the yarn when
heated by a pulse laser. This model can be used, as a tool to estimate the heat energy
required to fuse a given textured yarn.
