Abstract
Raw material comprises acid residues arising from the cottonseed cleaning process, which are subject to the following series of stages: a) neutralization of such residues; b) cleaning and purification of the residue of acid linter; c) chemical treatment by means of the action of alkalis; and d) water washing and subsequent thickening by means of filters. Such residues include some fibrils and cascamen, with a marked presence of vegetal elements typical of the seed (hull and remains of the degraded vegetal structure). After washing and subsequent thickening, the material is subject to the stages of: bleaching by means of chemical agents, washing and thickening, drying and dry grinding for reducing particle size.
