FIELD: biochemistry. n SUBSTANCE: invention relates to the chemical technology of fibrous materials and relates to perforated fibrous structures and methods for their manufacture. Perforated fibrous structures contain one or more fibrous elements – filaments, containing materials and one or more active agents that are capable of being released from the fibrous element under the conditions of the intended use. n EFFECT: invention provides the creation of filamentous fibrous structures containing active agents that are capable of being released from the active element under the influence of the conditions of the intended use, which are not characterized by dissolution properties, unacceptable to consumers, while having strength, flexibility and softness. n 15 cl, 17 dwg, 2 tbl |
