Effect of the Stretch Breaking Process on Fiber Length Distribution

The stretch breaking process has been useful in the cotton industry because long staple fibers such as wool need to be shortened so that they can be spun in the cotton spinning system with its higher production rate. The blending of wool with other fibers such as wool/cotton, wool/micro=fiber, and several wool blended yarns produced diverse wool products. In the present study, the distribution functions of the fiber length after the stretch breaking process are newly derived after considering the fiber's recovery function. The number of mean length of th fibers after the stretch breaking process are investigated by the computer simulation according to variables susch as the roller gauge, the breaking strain of the fiber, and teh standard deviation of the fiber length.
