Interfaces na produção de celulose solúvel: uma análise bibliográfica e bibliométrica

Abstract

This study proposes a literature and bibliometric review of dissolving pulp production from wood, exploring parameters related to raw material development and implications for improving textile derivatives. Dissolving pulp stands out in the production of basic materials for clothing and hygiene in the future, with hardwood and softwood species as its main sources. Since fabrics require a specific structural quality, this market shows significant differences from cellulose to paper, for instance. The wood composition is crucial for the final product and it was studied in this work along with processes used in industries aimed at adjusting the material to ensure yield and sustainability. In this sense, physical and chemical transformation processes were also presented, together with their possible contributions to reactivity and accessibility in the textile industry, ensuring the quality of the source up to the finished product. Steps of pulp production predominantly exemplified by the use of prehydrolysis Kraft and the acid sulfite method for pulp formation in specifications for fibrillation, as well as chemical recovery stages and conventional utilities of a factory, which were addressed in this review. The bibliometric analysis revealed a trend of growth in research related to dissolving pulp, considering its wide geographical distribution, number of interested authors, level of development, and relevance of the publications. Based on the diverse knowledge gathered in this monograph, it was possible to infer positive and negative correlations between forest development, pulp and textile industries. This multidisciplinary analysis reinforces the technological potential for obtaining impactful and economically profitable materials with a focus on sustainability. Finally, it emphasizes the need for future research aimed at understanding more interface parameters in a practical way, such as the adequate composition in the plant matrix (or wood mix) for better process efficiency in the pulp and textile industries, using innovative methodologies focused on access to structures, resource economy, and waste utilization.
