Abstract:
|
The growing conditions for cotton vary from growth region to growth region
within the United States. Growing and harvesting conditions can influence the
constituents and properties of the cotton fiber. It has yet to be determined how the
varying of conditions from growth region to growth region affect the color grade given
to cotton fiber and subsequently the dyeability of that fiber.
A total of sixty-four, l50-gram, samples of cotton fiber were obtained which
represented the 1997 cotton crop from the West, Southwest, Southeast, and Mid-South
regions. Each sample was processed into fabric, prepared, and dyed. After dyeing,
the CIELAB color and depth of shade values were evaluated to determine if sample-tosample
variation existed.
The results show that cotton fiber color grade has no influence on the color or
depth shade of prepared and dyed fabrics. Growth region, however, significantly
impacts color variation and dye uptake.
