	Shanghai twelfth silk fabric factory made of Shanghai 00000380 glass material. The weft density mirror is a simple measure for measuring the warp and weft density of all kinds of fabrics, such as silk, cotton and wool. As long as we choose the right density mirror (type) and the parallel (weft) line of the fabric, we can see a clear diamond shape. The scale shown on the top and bottom of the diamond corner is the number of lines per centimeter.
