Abstract
Description
- The present invention relates to compound forming fabrics for use in the forming section of a papermachine to manufacture graphical paper, board and packaging paper, or tissue paper.
- Compound forming fabrics are known in the art. Compound forming fabrics include a top or paper side weave and a bottom or machine side weave. The top and the bottom weave are bound together by binder yarns which alone or in combination can be binder warp or binder weft yarns and therefore weave with the top and bottom weft yarns of the top and bottom weave or with the top and the bottom warp yarns of the top and the bottom weave.
- The binder yarns further can be integral or so called fabric born binder yarns thereby forming at least an integral part of the top weave. U.S. Patent No. 5,152,326 describes a compound forming fabric having integral binder yarns arranged in pairs. Alternatively, the binder yarns can be additional binder yarns thereby forming no integral part of the top weave.
- A compound forming fabric having integral binder warp yarns which is made with a high warp density to provide adequate stability often has a top or paper side surface which is too closed to provide sufficient drainage. On the other hand, if the paper side surface is made less dense to provide sufficient drainage the fabric stability is not sufficient.
- Also a compound forming fabric with integral binder weft yarns which is made with a high weft density to provide adequate stability often has a to p or paper side surface which is too closed to provide sufficient drainage. On the other hand if the paper side surface is made less dense to provide sufficient drainage the fabric stability is not sufficient.
- What is needed in the art is a compound form ing fabric with good water drainage performance combined with sufficient stability.
- The present invention provides a compound forming fabric with good water drainage performance combined with sufficient stability.
- According a first aspect of the present invention there is provided a compound forming fabric with a top weave and a bottom weave, the fabric includes binder warp yarns, the binder yarns are arranged in groups of at least two interchanging binder yarns, wherein each group of said binder yarns forms an integral part at least of said top weave, wherein per group of binder yarns the number of bottom warp yarns only weaving the bottom weave is higher than the number of top warp yarns only weaving the top weave.
- The expression "interchanging" has to be understood in the sense that for each group at the same time only one of the binder yarns weaves the top weave and only one of the other binder yarns weaves the bottom weave. If a group comprises for example only two binder warp yarns this means that when the first of the binder warp yarns weaves the top weave the second of the binder warp yarn s weaves the bottom weave.
- According to the invention the bottom weave comprises one or more bottom warp yarns only weaving the bott om weave. Further according to the invention the top weave comprises no or one or more than one top warp yarn only weaving the top weave.
- By providing a compound forming fabric which has per group of binder yarns a greater number of bottom warp yarns only weaving the bottom weave than a number of top warp yarns only weaving the top weave , a sufficient stability in general, especially a good dimensional stability and a good wear resistance is achieved and at the same time an open structure is maintained.
- According to a preferred embodiment of the present invention, the number of bottom warp yarns only weaving the bottom weave is one more than the number of top warp yarns only weaving the top weave. It was found by the Applicant that by providing per group of binder warp yarns one more bottom warp yarn in the bottom weave than top warp yarn in the top weave, for many applications sufficient stability can by achieved by maintaining a fabric having a good open structure.
- According to a further preferred embodiment of the present invention there is foreseen that per group of binder warp yarns at least one of said bottom warp yarns only weaving the bottom weave weaves over and under the same bottom weft yarns like said group of interchanging binder warp yarns. Therefore at least one of said bottom warp yarns forms the same knuckles and floats with the bottom weft yarns like the group of binder warp yarns, thereby creating pairs of knuckles and floats allowing to use bottom weft yarns with larger diameter and thereby increasing the wear resistance of the compound fabric.
- The above mentioned principles are also applicable for compound forming fabrics having weft binders.
- Therefore according to a second aspect of the present invention there is provided a compound forming fabric having a top weave and a bottom weave, the fabric has binder weft yarns, the binder yarns are arranged in groups of at least two interchanging binder yarns, wherein each group of binder yarns forms an integral part at least of the top weave, wherein per group of binder yarns the number of bottom weft yarns only weaving the bottom weave is higher than the number of top weft yarns only weaving the top weave.
- Further, according to a preferred embodiment of the second aspect of the present invention the number of bottom weft yarns only weaving the bottom weave is one more than the number of top weft yarns only weaving the top weave.
- In addition, the present invention can include a compound forming fabric having weft binder yarns, wherein per g roup of binder yarns at least one of the bottom weft yarns only weaving the bottom weave weaves over and under the same bottom warp yarns like the group of binder yarns.
- The above mentioned advantages of the present invention are also applicable for compound forming fabric having binder warp yarns and binder weft yarns.
- According to a preferred embodiment of the present invention the binder yarns are arranged in pairs.
- According to a further preferred embodiment of the present invention there is provided a compound forming fabric having a top weave that include no top yarns weaving only the top weave and extending in the direction of the binder yarns. In the case of a warp binder system the top weave is formed by the weaving of the binder warp yarns with the top weft yarns and the bottom weave is formed by the weaving of the binder warp yarns and the bottom warp yarns with the bottom weft yarns . In the case of a weft binder system the top weave is formed by the weaving of the binder weft yarns with the top warp yarns and the bottom weave is formed by the weaving of the binder weft yarns and the bottom weft yarns with the bottom warp yarns.
- To increase the wear resistance of the compound forming fabric on the one hand and to provide an open top weave structure on the other hand it is desirable, if the diameter of the binder yarns is less than the diameter of the bottom yarns extending in the direction of the binder yarns.
- According to a preferred embodiment of the present invention the weave repeat of the compound forming fabric has 24 warp yarns or more. According to a further preferred embodiment of the present invention the weave repeat of the compound forming fabric includes 48 weft yarns or more.
- The above-mentioned and other features and advantages of this invention, and the manner of attaining them, will become more apparent and the invention will be better understood by reference to the following description of an embodiment of the invention taken in conjuncti on with the accompanying drawing, split among Figs. 1A, 1 B and 1C, wherein the sole drawing is a series of weft cross-sectional diagrams showing consecutive warp paths of all of the warp yarns in a compound forming fabric in accordance with the present invention.
