Antistatic finishes mechanisms

Surfactant-type antistats find the widest use because of thek low cost and minimal effect on the mechanical properties of the plastic. Ease of use is another favorable aspect to surfactants. They can be mixed with the bulk of the plastic prior to processing or can be appHed to the surface of the finished plastic article as the need dictates. 

In the case of 6.0-30 denier PP staple fibers for needle felts, the following requirements have to be met for spin and end finishes adjusted fiber-to-fiber friction for drawing good antistatic properties protection against mechanical damage with needlepunch processes one-way spin finish, i.e., the same spin finish for all positions.
