To Back, or Not To Back?

That is the question when considering the use of an acrylic or paper backed fabric for stretch systems. The answer is simple. Backed fabrics are not ideal for stretched systems. While the backing can protect against glue bleed through and prevent frayed edges, it also inhibits stretching. Backed fabrics are most appropriate for direct glue applications, though acrylic backed fabrics (with limited stretchability) can be used for tackable or rigid substrates. Backing a fabric can also cause it to lose its acoustical transparency.
