Most terry cloth is made
with cotton because the absorbent fiber gets stronger when wet and it can be
sanitized in very hot water using strong bleach and detergent without harm.
Terry cloth is usually made with looped pile because the loops act like very
small sponges. Looped pile is also better able to withstand the strain of
rubbing, pulling twisting and tugging by the user. Loosely twisted loops are softer and more
absorbent than tightly twisted loops, which produce a rougher fabric. Long pile
is more absorbent than short pile. The Red Brick features 2-ply cotton loop-in
terry cloth with nitrile blocks on both sides.
