Abstract

The invention discloses a preparation method of PBT silver-ion antibiotic moisture-absorption deodorization fibre, which comprises the following steps of: (1) crystallizing a material in advance, wherein the material is the mixture of a PBT slice and a silver-ion SHT antibiotic plastic master batch; concretely, crystallizing in advance by adopting dry hot air; (2) feeding the material in a screw type: firstly, drying the master batch by the hot air and then feeding the material obtained after mixing the master batch and the PBT slice into a screw extruder by a special master batch feeding machine which can measure the master batch; (3) filtering: filtering the mixture extruded by the extruder wherein the continuous production of spinning and the constancy of the pressure of the screw extruder are ensured during filtering; and (4) spinning: delivering the mixture from the filter to a spinning assembly, ejecting from a spinneret plate by the spinning assembly, and then coiling and forming. The fibre has favorable durability, dimensional stability and better elasticity, and the elasticity is free from the influence of the humidity.

Description

technical field [0001] The invention belongs to the technical field of fiber preparation, in particular to a method for preparing a PBT silver ion antibacterial, moisture-absorbing and deodorizing fiber. Background technique [0002] Many metal ions have bactericidal and anti-mildew effects. The antibacterial mechanism is generally divided into two categories: one is to destroy the structure of bacteria, and the other is to affect metabolism and physiological activities. Silver ions can kill bacteria by destroying the plasma membrane of bacteria. In addition, silver ions can destroy the three-dimensional conformation of proteases by combining with the sulfhydryl group (-SH) of proteins and kill microorganisms. Therefore, silver fibers (silver ions) provide dual functions of antibacterial and deodorizing. Bacterial growth will cause body odor. Coincidentally, qualitatively altered proteins will also produce odor on clothes and socks. The silver component on the surface of s...
