Abstract

A stratified press fabric (10) for the press section of a paper machine includes a base fabric (30) in the form of an endless loop. A first staple fiber batt material (40) is attached to the outer side of the base fabric (4 4) by needling. A fine fabric covers the first staple fiber batt material, and a second staple fiber batt material (50) is attached to the fine fabric by needling. The fibers making up the second staple fiber material are finer, that is, of smaller diameter or denier, than the fibers making up the first staple fiber material. The fine fabric prevents the coarser fibers of the first staple fiber batt material from being needled therethrough to mix with the finer fibers of the second fiber batt material.

Claims (14)

1. A stratified press fabric for the press section of a paper machine, said press fabric comprising:
a base support structure, said base support structure being in the form of an endless loop and having an outer side and an inner side;
a first staple fiber batt material attached to said outer side of said base support structure, said first staple fiber batt material comprising a plurality of first staple fibers;
a fine fabric, said fine fabric covering said first staple fiber batt material on said outer side of said base support structure; and a second staple fiber batt material attached to said fine fabric, said second staple fiber batt material comprising a plurality of second staple fibers, said second staple fibers being finer than said first staple fibers, wherein said fine fabric limits transfer of said first staple fibers and said second staple fibers therethrough and intermingling of said first staple fibers and said second staple fibers.
2. A stratified press fabric as claimed in claim 1 wherein said base support structure is a fabric selected from the group consisting of woven, nonwoven, nonwoven arrays of MD or CD oriented yarns, knitted and braided fabrics.
3. A stratified press fabric as claimed in claim 2 wherein said base support structure is an extruded mesh fabric.
4. A stratified press fabric as claimed in claim 1 wherein said base support structure is a strip of material spirally wound in a plurality of turns, each turn being joined to those adjacent thereto by a continuous seam, said base support structure being endless in a longitudinal direction, said strip material being selected from the group consisting of woven fabrics, nonwoven fabrics, knitted fabrics, braided fabrics and extruded mesh fabrics.
5. A stratified press fabric as claimed in claim 1 wherein said base support structure is an on-machine-seamable fabric.
6. A stratified press fabric as claimed in claim 1 wherein said fine fabric is a fabric selected from the group consisting of woven, nonwoven, knitted and braided fabrics.
7. A stratified press fabric as claimed in claim 5 wherein said fine fabric is an extruded mesh fabric.
8. A stratified press fabric as claimed in claim 1 wherein said fine fabric is a strip material spirally wound in a plurality of turns, each turn being joined to those adjacent thereto by a continuous seam, said fine fabric being endless in a longitudinal direction, said strip material being selected from the group consisting of woven fabrics, nonwoven fabrics, knitted fabrics, braided fabrics and extruded mesh fabrics.
9. A stratified press fabric as claimed in claim 1 wherein said fine fabric is an endless fabric.
10. A stratified press fabric as claimed in claim 1 wherein said first staple fibers have a first diameter and said second staple fibers have a second diameter which is smaller than said first diameter.
11. A stratified press fabric as claimed in claim 1 wherein said first staple fibers have a first cross-sectional size and said second staple fibers have a second cross-sectional size which is smaller than said first cross-sectional size.
12. A stratified press fabric as claimed in claim 1 wherein, said fine fabric has openings no larger than 0.50 mm in any dimension, so that said first staple fibers are not driven therethrough when said stratified press fabric is needled from said inner side of said base support structure.
13. A stratified press fabric as claimed in claim 1 wherein said support structure is comprised of two or more bases selected from the group consisting of woven, nonwoven, nonwoven arrays of MD or CD yarns, knitted, braided, extruded meshes of film structures.
14. A stratified press fabric for the press section of a paper machine, said press fabric comprising:
base support structure fabricated from yarns having one or more first effective diameter values and arranged so as to have a first mesh arrangement, said base support structure being in the form of an endless loop and having an outer side and an inner side;
first staple fiber batt material attached to said outer side of said base support structure, said first staple fiber batt material comprising a plurality of first staple fibers having one or more second effective diameter values;
a fine fabric fabricated from yarns having one or more third effective diameter values and arranged so as to have a second mesh arrangement, said fine fabric arranged on an outer side of said first staple fiber bait material; and a second staple fiber batt material attached to said fine fabric, said second staple fiber batt material comprising a plurality of second staple fibers having one or more fourth effective diameter values each smaller than the one or more second effective diameter values, wherein at least one of the one or more third effective diameter values and openings within said second mesh arrangement are respectively smaller than the one or more first effective diameter values and openings within said first mesh arrangement, and wherein said fine fabric limits transfer of said first staple fibers and said second staple fibers therethrough and intermingling of said first staple fibers and said second staple fibers.
