The plain cloth weaving method you mentioned refers to the weaving method of one piece (that is, sinking together)! Five pieces will be denser, many are used for satin, and the patterns will be more delicate, but the price is relatively more expensive; eight pieces will be looser, which is also a commonly used weaving method for double brocade. Double brocade is thicker and denser than single brocade, and is not so easy to deform. Generally speaking, the weft density can be divided into the written weft density and the upper machine weft density, and the number of teeth is equivalent to the upper machine weft density, which is adjusted on the loom. This should probably be it. If you want to be more professional, as mentioned above, asking the florist will make it clearer!
