Antibacterial silver-containing fiber with excellent biocompatibility and preparation method of antibacterial silver-containing fiber

Abstract

The invention relates to a preparation method of an antibacterial silver-containing fiber with excellent biocompatibility. The preparation method comprises the following steps: (1) alginic acid fiberfilament tows are pretreated in the mode that alginate fibers pass through an organic solution of sodium salt; (2) the pretreated alginate filament tows are mounted on a magnetron sputtering feeding roller; and (3) a vacuum sputtering coating chamber is sealed, and vacuumizing is conducted; and (4) gas is introduced, a treating power supply and a target table power supply are turned on, and the alginic acid fiber filaments are treated to obtain the antibacterial silver-containing fiber with the excellent biocompatibility. The fibers are treated, so that the structures on the surfaces of the fibers have certain flowing performance, deposition and attachment of silver atoms are facilitated, the working efficiency is greatly improved, and the production cost is lowered.

Description

technical field [0001] The invention belongs to the field of textile materials, and in particular relates to an antibacterial silver-containing fiber with excellent biocompatibility and a preparation method thereof. Background technique [0002] Common medical accessories in the medical field include textiles such as gauze and medical sponges. Most of the common medical accessories in the prior art are made of cellulose materials. However, cellulose materials lack antibacterial properties, poor hygroscopicity, and are difficult to Due to its own defects such as degradability, it needs to be replaced frequently in the process of being used as a medical dressing, and it has no obvious promotion effect on wound healing. In the process of changing medical dressings, it is easy to cause secondary damage to the patient's wound, especially For patients with large wound areas, such as burns, the replacement of medical dressings will cause great harm to the injured. [0003] In the ...

Problems solved by technology

However, adding nano-silver particles to the spinning stock solution has technical problems such as high cost, short antibacterial performance, and broken filaments during spinning. These are only the spinning process and are difficult to overcome. Due to the relatively severe hydrothermal reaction conditions and the treatment liquid contains a variety of particles, it will cause greater damage to the mechanical properties of the fiber
