Abstract
The present invention relates to an article of paper machine clothing for use in high temperature applications, which article comprises: a) a paper contacting surface layer adapted in use to contact a forming paper sheet; b) a base layer structure; and c) at least one intermediate layer disposed between said surface layer and said base layer structure, characterised in that said surface layer comprises a fibrous or continuous layer constituting a thermal barrier and providing properties of sheet release.
Claims23
An article of paper machine clothing for use in high temperature applications, said applications being those in which a paper machine press roll temperature is greater than 140.degree. C., said article comprising:
- a paper-contacting surface layer adapted in use to contact a forming paper sheet while said forming paper sheet is in contact with a press roll, said paper-contacting surface layer being a fiber layer acting as a thermal barrier to protect said article of paper machine clothing and providing properties of sheet release;
- a re-wet resisting sub-layer within said article of paper machine clothing and not in contact with said forming paper sheet, said re-wet resisting sub-layer providing resistance to re-wet of the forming paper sheet;
- a base layer structure;
- and
- at least one intermediate layer disposed between said paper-contacting surface layer and said base layer structure;
- said paper-contacting surface layer, said re-wet resisting sub-layer, said base layer structure and said at least one intermediate layer being joined to one another to form an integral structure;
- said thermal barrier being provided so that said at least one intermediate layer may include materials not otherwise suited for high temperature applications.
