What are the methods of making poplin?

Poplin is also woven with plain weave. Unlike plain cloth, the ratio of warp density to weft density is generally 1.8-2.2:1. Since the warp density is significantly greater than the weft density, a diamond grain pattern consisting of the raised parts of the warp yarn is formed on the surface of the fabric. Pure cotton or polyester-cotton fine yarn is often used to weave poplin fabric. According to the different yarns used, it is divided into yarn poplin, half-thread poplin (ply yarn is used in the warp direction), and thread poplin (ply yarn is used in both the warp and weft directions).
