That shouldn't be too hard...I guess :)
Use spheres in a #while loop to simulate a spiral-sort of
shape, or sine-wave...
The problem is, that this will clutter your file with
thousands (depending on the amount of precision you'd like)
of objects. Might parse a while if you plan to make a fine
weave :-)

Here's an example:

#declare S=sphere { 0, 0.4 pigment { color rgb
<0.8,0.5,0.5> } }

#declare T=0
#while (T<100)
    #object { S translate <T/10, sin (pi*(T/12.5)),0> }
    #declare T=T+1
#end

This will create a string of 100 spheres in the form of a
sine wave, 10 units long (x), 1 unit amplitudo, so 2 units
high (y) with 4 sine waves (y function from 0 to 8*pi). Of
course, this is not a cylinder (as you ask for) but the
result should be better than lining up cylinders crosswise.

Hope this helps.
