<p>A method of manufacturing a particle-bonded nonwoven liner material (30) having antistatic and laminating properties whereby binder particles of thermoplastic material are precipitated from a water-based solution (34) by the addition of a precipitant having antistatic properties, preferably a di-ethyl sulfate quaternary of a complex cyclic amine. When the precipitant is added to a water-based dispersion of polyester resin, the material precipitated from the dispersion is a composite of polyester and precipitant, which composite material is antistatic. The composite material is also thermoplastic, which results in excellent laminating strength at high production line speeds. This antistatic composite material serves as the binder which holds the nonwoven fabric (30) together after being applied thereon and then dried.</p> |
