Abstract

The invention provides a processing technology of an antibacterial and deodorant chinlon filament and the chinlon filament, and relates to the technical field of textile technologies. The processing technology of the antibacterial and deodorizing chinlon filament comprises the following steps: mixing quaternary ammonium salt organic antibacterial factor powder with a grafting compatilizer, and carrying out hot melting to obtain a molten quaternary ammonium salt polymer; chinlon slices are dried and then hot-melted into molten chinlon; the preparation method comprises the following steps: mixing a molten quaternary ammonium salt polymer and molten chinlon, heating, and extruding through a screw extruder to obtain antibacterial and deodorant chinlon master batch; blending the prepared antibacterial and deodorizing chinlon master batch with chinlon slices to obtain a blend, carrying out hot melting and spinning extrusion on the blend to form tows, cooling a yarn chamber, molding, wetting, feeding oil and winding to obtain the antibacterial and deodorizing chinlon filament. The technological process is simple, and the preparation mode is economical and applicable. The invention also provides a chinlon filament which is prepared by adopting the processing technology of the antibacterial chinlon and has the advantages of long antibacterial time and good deodorization effect.

Description

technical field [0001] The present application relates to the technical field of textile technology, in particular, to a processing technology of antibacterial and deodorizing nylon filaments and nylon filaments. Background technique [0002] The application of antibacterial materials in the field of biomedical materials has attracted more and more attention. In order to make general materials have antibacterial functions, the main method at present is to embed, blend, coat, coat, and graft the antibacterial substances on the surface. Modification and other methods are applied. [0003] At present, there are three main ways to prepare antibacterial fibers: inorganic antibacterial, organic antibacterial and natural antibacterial. [0004] Among them, organic antibacterial refers to the antibacterial substances that use organic acids, phenols, quaternary ammonium salts and other organic substances to achieve antibacterial. Organic antibacterial is cheap and stable in color, ...
