Abstract
Methods and apparatus for plasma modifying a substrate are disclosed along with associated techniques for applying coatings to the substrate. Particular utility has been found using a hollow cathode to generate the plasma along with magnetic focusing means to focus the plasma at the surface of a substrate.
Claims9
An apparatus for plasma treating a textile substrate, the apparatus comprising:
- a housing having entry and exit positions, plasma generating and plasma target sides opposite to each other with a substrate receiving channel extending therebetween, and air locks at the entry and exit positions for maintaining vacuum under operating conditions;
- a cathode plasma generator comprising a plurality of hollow cathodes mounted on the plasma generating side;
- and
- a plurality of focusing arrays opposite to the plasma generator to focus the plasma across the channel and across a surface of the substrate as it passes through the channel.

An apparatus for modifying at least one surface characteristic of a textile substrate, the apparatus comprising:
- a housing having entry and exit positions, a plasma generating side, a plasma target side opposite to the plasma generating side, a channel extending therebetween for passing the substrate between the sides of the housing and air locks at the entry and exit positions for maintaining vacuum under operating conditions;
- a plasma generator comprising a plurality of hollow cathodes mounted on the plasma generating side;
- a plurality of focusing arrays opposite to the plasma generator to focus the plasma across the surface of the substrate to be treated as it passes through the channel;
- and
- means for coating the plasma treated substrate.
