Analysis of ISO 4913 Test Method for Cotton Fiber Length
ISO 4913 is an international standard method for determining the span length and uniformity index of raw and semi-processed cotton fibers. Based on optical scanning technology, this standard obtains continuous information on fiber length distribution through non-destructive measurement of processed cotton fiber bundles, thereby assessing the spinnability and processing stability of cotton fibers. Cotton fiber length is one of the important fundamental indicators determining yarn strength…
