The Possibility of Producing Medium Density Fiber board (MDF) from Cotton  Stems (Gossypium sp.) and Determination of its physical- and mechanical Properties

• This investigation has established the Possibility of Producing Medium Density Fiber board (MDF) from Cotton Stems (Gossypium sp.) left after cotton picking. This product has good physical-( moisture content, density, absorption and cross-swelling after 2, 24, and 48 hours) and mechanical Properties (binding strength and cross-tensile strength) and is very economical. Although the mean of values for cross swelling and absorption were higher than the mean of values for cross swelling and absorption of standard Medium Density Fiber board (MDF) which have been determined according to European Norms EN (DIN, 1999). These values were satisfactory, because we didn't use the water proofing material (Parafin emulsion) when producing the Medium Density Fiber board (MDF) which is normally used in Europe (between 0.25-1 % according to the dry weight of the fibers) Haygreen et. al., (2003).
