Lawn is the name of the material that is connected to the walls of a frame to form a sieve or screen. Liquids and powders are passed through the lawn for mixing and cleaning. It was originally made of silk or linen, but now it is usually metal for sieves and nylon for screens. It has a mesh, which are the tiny holes left between the woven threads. The lawns are made with different sizes of mesh, from 40 for a very coarse material, to 200 for a very fine one and they are graded by threads per inch.
