SCI means in textile is Spinning Consistency Index. SCI indicates the prediction of spin ability and quality of cotton fiber to predict yarn quality results. HVi ( High volume instrument) predicts SCI from individual results tested throughout the entire measurement. It is based on entire testing and data taken from USDA (United States Department of Agriculture) to calculate this factor.
What is the formula for SCI cotton?
SCI calculated by the below question
SCI=-414.67+2.9*strength-9.32*Micronaire+ 49.17*UHML+4.74*UI+0.65*Rd+0.36*(+b)
Where:
- UHML is the upper half mean length in inches.
- (UNF) UI is the uniformity index.
- Rd is the reflectance degree.
- (+b) is the degree of yellowness of cotton fiber.
Better Spinning consistency index values good results can be achieved in spinning and vice versa.
