> Plain cloth with polyester has a tensile strength of 30 k# (thousand

Please forgive the following potentially stupid question, but isn't the above comparing apples and oranges? ie. "plain cloth" versus "8 harness satin" I assume these cloth types are NOT the same, otherwise the same name would've been used for all three cases. What's goin' on here?
