What is a “railroaded” fabric?
A common term used in home interior textiles is the term “railroaded” when referring to the intended orientation of a fabric. Designer fabrics are made in (usually) a 54″ width. This means the fabric is woven in a piece 54″ wide, and in nearly unlimited lengths. After it is woven, the fabric is rolled onto a bolt for shipping and storage, so there are no creases in the fabric. Weaving fabric “railroaded” allows you to cover the entire width of the sofa in one horizontal piece of fabric – without seams. Some plain fabrics can be turned in any direction, so the importance of railroading a fabric is not as important when dealing with these plains; however, when considering a Jacquard woven fabric with a specific design (often with a larger repeat or clearly recognizable image), whether a pattern is railroaded or not can make a huge difference in its application capabilities.
There are times when the common 54" width of fabric is not enough to run the span of a piece of furniture. For instance, if you have a very long cushion that exceeds the width of the fabric, instead of putting in a seam or two you could try to find a railroaded pattern and you could run right across with no seams. The same would apply to sofa backs as well. Sometimes it is more efficient to cut fabric that is railroaded even if you don't have a large span because the pattern may be unusual and difficult to match.
On applications such as pillows, many Jacquard patterns can be used in either direction due to the smaller cut size required. In the illustration below, consider the iron railroad “tracks” the “selvages” (or edges) of the roll of fabric. The pattern would be considered cross ties. If the intended top and bottom of the design motif is pointing toward the two iron “tracks,” the fabric can be woven at any length to span the length of the sofa back and beyond. If the intended top and bottom of the design motif is pointing right and left along with the “cross ties” of the railroad tracks, the pattern could look odd when applied to the sofa back. Most of our Revolution Performance Fabrics are woven railroaded. In rare occasions, they may be run “un-railroaded” which is often referred to as being woven “up the roll.”
