SCI

SCI means Spinning Consistency Index. SCI is a calculation for predicting the overall quality and spin ability of the cotton fiber. The regression equation uses most of the individual HVI measurements, and is based on the data taken from United States Department of Agriculture's (USDA) annual crop reports.

The regression equation used to calculate the SCI is as follows:

SCI= -414.67+2.9*strength-9.32*micronaire+49.17*UHML+4.74*UI+0.65*Rd+0.36*(+b).

Where,

            UHML= Upper Half Mean Length.

     UI= Uniformity Index.

            Rd= Reflectance degree.

            (+b)= Yellowness of the cotton fiber.
