The secrets of our water-repellent finish

Have you ever wondered what we do to make our fabrics water repellent?
To answer that question we need to talk about how a water-repellent finish works. A common technique is to add a PFC (perfluorcarbon) chain. This is a chain of carbon with fluor on each carbon. Water and oil can’t get past the fluor, thus making the fabric water and oil repellent. Sounds great right? Not quite. One of the carbon molecules, C8, was added to the list of Substance of very high concern of the European legislation on chemicals (REACH). Its siblings, C6 and C4, are likely going the same way. Symphony Mills saw this and started looking for less harmful alternatives.
