Woven fabrics are thin (usually less than 5 mm), wide (usually up to 1.5 m and sometimes up to 12 m), and of varying length. Lengths of fabric supplied for commercial use are called pieces and are usually 20â40 m long. Narrow strips less than 0.4 m wide are also produced. Classification of woven fabrics. Woven fabrics are classified by fiber composition and purpose, as well as by the methods used in production, finishing, and dyeing.

Soil fertility is greatly influenced by the factors of soil formation. As soils form, nutrients are being continually removed from and added to the soil with time. The conditions that are present during soil formation ultimately determine how much and what kind of nutrients the soil can naturally supply and hold.arent material is the starting point for most soil development. The parent material may be mineral rock and/or organic matter. When parent rock material is exposed to the atmosphere or when organic matter and/or minerals are deposited on the earthâs surface, soil formation begins.
