1200D Shandong Silk PU (WR)

1200D Shandong Silk PU (WR) is likely a type of fabric used in the manufacturing of clothing or other textiles. "1200D" likely refers to the denier, a unit of measurement for the thickness of a fabric's fibers. Denier is the weight in grams of 9000 meters of the yarn. The higher the denier, the thicker and stronger the fabric. "Shandong Silk" refers to silk fabric produced in Shandong, a province in eastern China. "PU" likely stands for "polyurethane," a type of synthetic material often used as a coating or finish on fabrics to make them water-resistant. "WR" stands for water-resistant. So, this fabric is likely a thick, strong silk fabric with a water-resistant polyurethane coating produced in Shandong, China.
