Problems solved by technology

[0006] CN103015166B provides a nano-silver antibacterial fabric and a preparation method thereof. First, the method of solution chemistry is used to grow zinc oxide nanowires on the surface of the fabric, and then the nano-silver particles are deposited on the zinc oxide nanowires by soaking and photoreduction. This method uses coating and deposition to process zinc oxide nanowires and nano silver particles on the surface of the fabric. Although it has certain antibacterial properties, compared with the method of chemical grafting, this method has the problem of poor washing stability.
However, the antibacterial agent used in this method has hydrophobic properties, and the cotton fabric itself has good hydrophilicity, but after antibacterial finishing, a part of the hydrophilic hydroxyl group on the surface of the fabric is reacted, and because the hydrophobic antibacterial agent covers the surface of the cotton fabric, so The prepared antibacterial textiles have poor hydrophilicity, which affects the comfort when worn

Abstract

The invention provides a method for preparing antibacterial polyester by using a halamine compound and a silver ion. The preparation method comprises the following steps: immersing a polyester fabrictreated by sodium hydroxide in antibacterial finishing liquid prepared by the halamine compound and acrylic acid, after padding, placing the fabric under a high-energy electron beam for radiation, after the radiation, baking, washing and drying the fabric, placing the fabric in a silver nitrate solution with a certain concentration for a certain period of time, and then drying the impregnated fabric to obtain an antibacterial polyester fabric. The method for preparing the antibacterial polyester by using the halamine compound and the silver ion solves a shortcoming of poor hydrophilicity of the polyester fabric, adopts an electron beam radiation finishing method to combine the halamine compound with the polyester, and a problem that the halamine compound is difficult to be modified on thepolyester fabric is overcome. After finishing, the hydrophilic property of the polyester is greatly improved, and the antibacterial polyester fabric has excellent antibacterial properties and exhibitsan important industrial application value by adopting the halamine compound and the silver ion for antibiosis together.

Description

technical field [0001] The invention relates to the technical field of textile antibacterial finishing production, in particular to a finishing method for preparing antibacterial polyester by using halide amine compounds and silver ions. Background technique [0002] As an indispensable consumer product in daily life, textiles have attracted more and more attention to their hygienic performance. The widespread existence of bacteria and other microorganisms makes textiles very easy to become a breeding ground for bacteria in the process of taking, storing, and transporting, which poses a threat to human health. Therefore, it is of great significance to carry out antibacterial finishing on textiles. [0003] Polyester fiber macromolecules are tightly arranged and have a symmetrical structure, which makes polyester fabrics have good chemical and mechanical properties. However, due to the lack of hydrophilic groups in polyester fiber macromolecules, polyester fabrics have poor ...
