Pile Surface: It is possible to produce Chenille in a variety of grades, depending upon the height of pile and the closeness of weave. It is often true that a Chenille made of the finest worsted yarn, closely woven, with a smooth, velvety surface, has a comparatively low pile, while another with a high pile of a luxurious appearance may be made of a rough, soft woolen yarn, more loosely woven, and is consequently of a considerably inferior quality to the first carpet and sells for a lower price.
In addition to these Oriental knots, there is another used by Spanish wreavers that is called a single knot. To produce this knot, each warp thread is completely circled by each pile thread, the two, ends of the latter being brought upward to form the pile surface. There is a separate weft system of threads that serves to hold the warps together.
• Air; moisture and nitrogen are all necessary if bacteria and fungi are to break down the raw material efficiently. Air is allowed in through the base and sides of the pile. Water should be applied with a can or hose if the pile shows Signs of drying out, and moisture can be kept in by covering the pile with sacking, old carpet or polyethylene sheeting. Nitrogen must be provided in the form of grass mowings, young nettles or manure, or by adding a compost activator • Site the pile in a sheltered and shady place but not under trees or where tree roots ma move into the compost. It mi be protected from the drying sun and wind. Allow ample time for decomposition. |
