The idea of dyeing yarns dates back to neolithic times, some 5000 years ago on the continent of Asia. China has been using dyes generated from plants, minerals and insects for at least this far back in time. Until the mid 1800s, yarns were "package dyed" (individual skeins or cones of yarn were dyed prior to weaving into fabric). In 1849, a new process of dyeing fabrics began in Lyon, a city in France. This process involved "piece dyeing" where a plain white or light colored fabric is woven and then dipped into a dye bath, and then allowed to cure before being washed and dried.

A Brief History of Yarn Dyeing : Revolution Fabrics
The making of synthetic dye
The first synthetic dye named "mauveine" was accidentally discovered by chemist William Henry Perkin in 1856. With his discovery, chemists began to feverishly develop new and improved synthetic dyes such as fuchsine, safraninie, and induline. Since then, thousands of synthetic dyes have been produced.
solution dyed vs piece dyed
Fast forward to the 1950s when European chemists discovered and perfected a new form of dyeing called "solution dyeing." When synthetic fibers (such as acrylic, nylon and polyester) are made, the liquid chemical solution that makes up the fiber is forced through tiny holes in an item called a spinneret, extruding long fibers – think of water being forced through a shower head. During this process, dyes are impregnated into the extruded fibers, thus creating an almost endless variety of colors. Solution dyeing is not applicable to natural fibers (such as wool) because the fibers are already in existence.
With piece dyeing fabrics and package dyeing yarns, the advantage is that one can dye as little or as much as needed. Solution dyeing requires larger quantities of yarn to be produced (ie larger runs). For the fabric weaving industry, this creates limitations. Where one could create an infinite amount of custom colors in the package dyeing process, solution dyeing requires weaving mills to purchase much larger quantities of a single color.
Solution dyed yarns today
All Revolution Performance Fabrics are made of solution dyed polypropylene. These fabrics are inherently stain resistant, have a relatively longer life span, and can even be cleaned with bleach, whereas package dyed yarns cannot be bleach cleaned. Since Revolution Performance Fabrics are solution dyed, the process of adding stain resistant treatments to the fabrics is eliminated. This is great news for the consumer because some of these treatments contain PFCs (Perflourinated Chemicals). Studies have suggested that PFCs could be linked to a variety of health concerns.
