Abstract
A papermaker's fabric woven from uniformly precoated, totally encapsulated monofilament yarns is disclosed. The yarns are coated prior to the weaving of the papermaker's fabric in order to impart anti-sticking characteristics to the papermaker's fabric. The coatings may be such that thickness of the machine direction yarns is different than the thickness of the cross-machine direction yarns.
Claims11
A papermaker's forming fabric comprising an endless belt woven from:
- monofilament machine direction yarns precoated prior to weaving with a polymer to impart anti-sticking characteristics to the papermaker's forming fabric and having a uniform, polymeric coating of a first thickness;
- monofilament cross-machine direction yarns precoated prior to weaving a polymer to impart anti-sticking characteristics to the papermaker's forming fabric and having a uniform, polymeric coating of a second thickness, said first and second thicknesses being different.
A papermakers forming fabric comprising an endless belt woven from monofilament yarns uniformly encapsulated prior to weaving with an anti-sticking polymeric coating which the pulp will not stick to, wherein said coating material is a polyester having a lower melting point than the melting point of said monofilament yarns.
A method for producing a papermakers forming fabric comprising the steps of:
- producing monofilament yarns;
- uniformly coating said monofilament yarns with a film of polymeric material selected to impart anti-sticking characteristics to the finished forming fabric;
- and
- weaving the papermakers forming fabric from said coated monofilament yarns, wherein a thickness of said coating on crossmachine direction yarns is different from a thickness of coating on machine direction yarns.
A method for producing a papermakers forming fabric comprising the steps of:
- producing monofilament yarns;
- uniformly coating said monofilament yarns with a film of polymeric material selected to impart anti-sticking characteristics to the finished forming fabric;
- and
- weaving the papermakers forming fabric from said coated monofilament yarns, wherein said polymeric material is a polyester having a low melting point compared to the melting point of said monofilament yarns.
