For a comparison of polypropylene, polyester, and nylon as used in the concrete
industry, see: http://www.nycon.com/products/products.htm. It does not suggest
where the clay artist may purchase smaller amounts, but the information is
interesting. Evidently, many industries manufacturing with concrete use nylon
fibers, so a local concrete contractor may indeed have nylon fiber available.

This is a great site Helen has told us about!
I did not have good luck with the fiber I found being used for concrete.
It works but it is very hard to mix thoroughly into the clay.
The fiber which I tried was coarser than the fiber I got specifically
for clay. The fiber for concrete came in a soluble paper bag, 1.5 pounds
intended for a cubic yard of concrete. That's similar to the one pound/ton
fiber/clay ratio I've seen recommended. The batch plant threw a bag in per
yard, and relied on the mixing action to break the bag and mix the fiber
into the concrete. The grinding action of concrete on the fiber is
considerable, and breaks the fibers apart. We have no similar action in
clay mixing. I'd suggest looking closely at any fibers you find intended
for concrete to make certain they will work the way you want in clay.
The fiber I found at the cement plant was labeled "Fibermesh" and is
made by a company called Synthetic Industries. The fiber is about 3/4-inch
long (19mm), relatively coarse and slightly flat in cross section.
According to the web site Helen found, it is polypropylene.
I'd appreciate hearing from others what manufacturer, and if possible,
what product name, is on the fiber they have had good success with in clay.

Your posting about the coarseness of the fibers obtained at cement
factories, etc. gave me an idea, and I'm posting this to see if my
brainstorm (?) is at all valid. Pull the idea apart, by all means, fellow
Could the coarse fibers be mixed with minimal percentages of clay to make
a sculpture armature upon which to build a sturdier piece with little or no
fiber? Just an idea to tuck away for those far off days when I have time
to do all those extra projects....... CNC
