| Abstract: |
| This paper reviewed the technological advances of preparing dissolving pulp from cotton fibers， and discussed the differences in the characteristics of two types of raw materials with cotton linter and waste cotton textiles， along with their effects on the dissolving pulp pulping process. From the perspective of the key quality indicators system and range of dissolving pulp， a comparative discussion was made on the traditional and modern pulping methods for cotton linter， as well as the decolorization processes for waste cotton textiles including oxidative decolorization， reductive decolorization， and enzymatic decolorization. The diversified development of dissolving pulp and regenerated fiber preparation technology was summarized， with the aim of providing a reference for the high-value utilization of waste cotton textiles. |
