Poplin

Poplin (also known as broadcloth in North America) is woven with a warp-dominant plain weave in which more threads run in the warp than the weft, or the weft thread is slightly heavier, producing a subtle horizontal rib invisible to the untrained eye. The dense warp creates a characteristically smooth, even surface that photographs well and holds a pressed crease. Cotton poplin for shirting is typically woven at 80–100 threads per inch and finished with a calendering pass for additional smoothness. It wrinkles more readily than heavier weaves due to the lack of textural elasticity, but accepts classic starch-and-iron finishing reliably. Polyester-cotton blend poplins (65/35) trade some hand quality for wrinkle resistance in wash-and-wear applications.
