The Technological Worth of Cotton: Textile Industry Perspective

Yehia El Mogahzy


 
ABSTRACT

In this paper, a systematic procedure to determine the technological value of cotton is proposed. This procedure reflects the industrial perspective of the real value of cotton fiber with respect to its various attributes. The underlying concept of this procedure is a premium/discount value model that can be used effectively to determine the technological value of a cotton bale or a shipment of cotton bales. The model provides a better resolution of fiber attributes than that used by the current classing system. The model uses a database consisting of HVI and AFIS fiber properties and corresponding data of processing performance parameters, and yarn or fabric quality parameters to form a multi-variable contribution matrix. This matrix represents the main structural element of the model. Other elements of the model include anchored parameters such as zero-base values, and difference factors. The model output consists of three technological premium/discount indices (PDI Trilobate System): quality premium/discount index (QPDI), performance premium/discount index (PPDI), and fiber defects premium/discount index (FDPDI). These indices may be used separately, or collectively to determine the technological worth of fibers with respect to a particular process or end product.
