Latest Patents

Yutaka Maeda holds 1 patent for his invention titled "Surface-modified cellulose acetate filaments and a process for producing." This patent describes a method for creating surface-modified cellulose acetate filaments that possess a microporous structure in their peripheral surface layer. The process involves bringing non-modified cellulose acetate filaments, with an average degree of acetylation of 50 to 62%, into contact with an organic solvent capable of dissolving or swelling the filaments. The rapid evaporation of the solvent results in filaments that exhibit a silklike touch and an increased intensity in dye exhaustion, ranging from 1.1 to 2.0 times that of the non-modified filaments.
