Anti-tightening-mark stretch-proof loose-top sock and preparation method thereof

Abstract

The invention relates to the technical field of high polymer materials, and discloses an anti-tightening-mark stretch-proof loose-top sock and a preparation method thereof.The anti-tightening-mark stretch-proof loose-top sock is obtained by weaving and processing cotton fibers and spandex into socks and treating the socks with a treating agent. In the dipping process, carboxyl in the carboxyl carbon nanotubes, terminal hydroxyl in sulfur-containing polyurethane and phenolic hydroxyl in imidazole modified sodium sulfonate are subjected to esterification reaction, a cross-linked network is formed among the carboxyl carbon nanotubes, the terminal hydroxyl in sulfur-containing polyurethane and phenolic hydroxyl in imidazole modified sodium sulfonate, connection is tighter, and when the carboxyl carbon nanotubes are applied to socks, the tensile property and elasticity of the socks are enhanced, and the service life of the socks is prolonged. And the carbon nano tube has better tensile property and elasticity. Sulfur elements, phosphorus elements, nitrogen elements and sulfonic acid groups in the sulfur-containing polyurethane and the imidazole modified sodium sulfonate have relatively good flame retardant property, and jointly form a flame retardant system, so that a relatively good flame retardant effect is achieved.
