Abstract
A multi-layer monofilament consisting of multiple layers that are extruded simultaneously in a single process step, having a first layer made from plastic A, a second layer, which is bonded directly to the first layer, made from plastic b, and a third layer, which is bonded directly to the second layer, made from plastic C, plastic B being a bonding agent between the two plastics A and C.

A multi-layer monofilament consisting of multiple layers that are extruded simultaneously in a single process step, having a first layer made from first plastic, a second layer, which is bonded directly to the first layer, made from a second plastic, and a third layer, which is bonded directly to the second layer, made from a third plastic wherein the second plastic is a bonding agent for bonding the first and third.
A method of making a multilayer monofilament which comprises the steps of:
- spinning a liquified plastic core from a spinning orifice;
- applying two to said core at least one synthetic resin bonding agent to form an inner sheath on said core as said core emerg s from said orifice;
- and
- applying to said inner sheath an outer sheath of a synthetic resin to which the synthetic resin of said inner sheath can bond as said core passes out of said spinning orifice.
