Polyamide adsorbent resin is a newly developed class of organic molecular polymer adsorbent, polyamide is nylon material. It has strong adsorption properties for flavonoids. Polyamide resin has the advantages of high physicochemical stability, unique adsorption selectivity, unaffected by the presence of inorganic substances, long service life, and cost saving, and is now widely used for molecular distillation of fiber materials .
The molecular distillation of fiber materials includes pre-treatment, feeding,thin-film evaporation, molecular distillation, heating system, separation and purification, cooling system, generation of polyamide resin, and collection. After such a variety of distillation industrial processes, the performance of the fiber material is improved and enhanced.
