Machine-made rugs can be made of various
materials, including heat-set polypropylene, faux silk
viscose and wool. Machine-made rugs are woven on power
looms, where the pile yarns and the backing yarns are
threaded into the machine ahead of time. A computer
controls which colors are woven into certain parts of
the fabric, creating the original design.
Power loom weaving is very fast, but usually only
allows for a limited number of colors at a time.
Machine-made rugs can run a wide range of pricing from
expensive, high-quality weaves to low, promotional
rugs.
