Problems solved by technology

The preparation and application process of this method is relatively complicated, and the cost is high. When adding the discoloration inhibitor, a series of problems such as dispersion and dosage will be encountered, and it is not suitable for antibacterial finishing of textiles.
Therefore, the discoloration problem of silver salt antibacterial agents has seriously restricted its application in antibacterial textiles, and this has also become a major problem in the field of silver-containing antibacterial agents.

Abstract

The invention relates to a method for finishing anti-discoloration silver salt antibacterial fabric. The method comprises the following steps: the fabric is dipped and rolled twice in a finishing solution, pre-dried at 80 DEG C, dried at 120 DEG C and then washed; and the fabric is dipped, padded or padded-stacked in two different finishing solutions respectively, pre-dried at 80 DEG C, dried at 120 DEG C and washed. The method has the advantages that the method is high in the anti-discoloration performance of antibacterial agent on the fabric finished by the method, and strong in the adhesive force of the antibacterial agent on the fabric and excellent in antibacterial ability, reduces the thickness of a fabric coating, has no influence on the hand feeling, whiteness and strength of the fabric, and is simple in preparation method, low in cost and easy to industrialize.

Description

technical field [0001] The invention relates to a finishing method of an anti-discoloration silver salt antibacterial fabric. Background technique [0002] At present, inorganic silver salt is an antibacterial agent widely used in antibacterial finishing of textiles. Because of its outstanding antibacterial ability and the highest safety, silver ions are the first choice for designing ionic antibacterial materials. However, during use, the silver ions in the antibacterial agent are easily oxidized into elemental silver or silver oxide under air and light, resulting in discoloration of the silver salt antibacterial agent, which not only reduces the antibacterial performance, but also affects the appearance and color of textiles. . Therefore, how to avoid the discoloration of silver ions is a prominent problem in the preparation of silver salt antibacterial fabrics. [0003] At present, domestic and foreign research on the anti-tarnish of silver salt antibacterial agents ma...
