Abstract:
... Cotton fiber length is an essential parameter for the cotton industry and cotton research. However, differences between industry- and laboratory-scale ginning may lead to inconsistencies between research and industry results for measured length. Seedcotton from farms is processed in large industry-scale gins, while researchers typically use small laboratory-scale gins. The proposed method successf ...

In this work, an emerging organic solvent degumming process utilizing FeCl₃ catalyst (FeCl₃-OS) was developed in one step. The influences of FeCl₃-OS system on fiber properties (e.g. residual gum content, tenacity, degree of polymerization (DP), etc.) were eval ...
