In footwear manufacturing, hot melt sheets are crucial shaping materials for areas like the toe and heel, with their performance directly influencing the shoe’s support, durability, and comfort. The four commonly used raw materials to produce Footwear Hot Melt Sheet include PETG chips, low-melting point polyester (LMPET), TPU (Thermoplastic Polyurethane), and EVA (Ethylene-Vinyl Acetate). These

This article introduces the types of cationic polyester chips and their cationic dyeable mechanisms. It also outlines the production process for cationic polyester, highlighting important considerations. Furthermore, the dyeability and spinnability of cationic (CDP) chips are explored. Cationic dyeable polyester chips are obtained by introducing a third monomer into the macromolecular chain of PET, resulting in
