Abstract

The invention discloses antibacterial nanofibers or master batches and a preparation method thereof, including components of an antibacterial polymer resin solution and the preparation method of the antibacterial nanofibers or master batches. The antibacterial nanofibers or master batches are characterized by being formed through electrostatic spinning, melt-blowing, fibrillation and two-component compound methods on antibacterial polymer resin solution. Photosensitive molecules in the antibacterial nanofibers or the antibacterial master batches are antibacterial, do not generate a dissolution phenomenon, and are high in efficiency, wide in spectrum and antibacterial; the high temperature resistance of an organic antibacterial agent material is effectively provided; and the application range of an antibacterial agent is further expanded.

Description

technical field [0001] The invention belongs to the field of textiles, and specifically relates to an antibacterial and mildew-proof antibacterial nanofiber or an antibacterial master batch and a preparation method thereof. Background technique [0002] Traditional nanofibers have a wide range of applications in air filtration, water treatment, catalysis, medicine and other fields due to their small fiber diameter, small pore size, high porosity, and large specific surface area. However, adding various small-molecule nanoparticles into the spinning solution not only increases the difficulty of the spinning process, but also greatly reduces the active point of the functional material, which greatly increases the cost. CN201510737628 discloses a method for preparing an antibacterial nanofiber membrane. The surface-modified porous nanofibers are used to form a shell-core structure membrane, and at the same time, some other nanoparticles, such as metallic silver, copper, zinc, m...
