Embodiment 1

[0018] The preparation method of the superfine silver-plated antibacterial nylon fiber involved in this embodiment includes the following steps:

[0019] Step 1. Clean the nylon fiber: immerse the nylon fiber in a 10% acetone aqueous solution, wash with ultrasonic water for 10 minutes, then wash and dry with deionized water, and set the drying temperature to 100°C to remove the surface of the nylon fiber Oil and dirt;

[0020] Step 2: Activate, sensitize and catalyze the nylon fiber: soak the nylon fiber in a hydrochloric acid solution with a concentration of 0.1g / L, perform surface activation treatment for 60 minutes, then wash, dry, and dry at 100°C ; Then dissolve stannous chloride in 0.1g / L hydrochloric acid solution to prepare a sensitizing solution with a concentration of 20g / L, soak the activated nylon fiber in the sensitizing solution for 30 minutes, then take it out, wash and dry Dry it at a drying temperature of 120°C; then immerse the activated and sensitized nylon fibe...

Abstract

The invention belongs to the technical field of chemical fiber processing, and particularly relates to a preparation method of superfine silvered antibacterial nylon fibers. The preparation method comprises the following steps of: S1, carrying out cleaning on nylon fibers, i.e., immersing the nylon fibers into aqueous solution of acetone, and by ultrasonic washing, removing oil and dirt on the surfaces of the nylon fibers; S2, carrying out activation, sensitization and catalysis processing on the nylon fibers; and S3, carrying out silvering on the preprocessed nylon fibers, inducing to carry out oxidoreduction on the surfaces of the nylon fibers, cleaning the nylon fibers with deionized water, and drying to obtain the silvered antibacterial nylon fibers. The process method for preparing the silvered antibacterial nylon fibers, which is disclosed by the invention, is simple, convenient and efficient, can be used for industrial continuous production and is low in cost.

Description

Technical field: [0001] The invention belongs to the technical field of chemical fiber processing, and specifically relates to a preparation method of ultrafine silver-plated antibacterial nylon fiber. Background technique: [0002] The scientific name of nylon is polyamide fiber, commonly known as nylon, which has the advantages of high strength, excellent wear resistance and good resilience. Nylon has heat setting properties, which can maintain the bending deformation formed when heated. Nylon fabric is known for its excellent abrasion resistance and thin texture, so it is the best choice for sportswear, swimwear, fitness clothing, down jackets, and mountaineering clothing materials. With the development and progress of science and technology, people have put forward higher requirements on the properties of nylon fibers. By plating the surface of nylon with silver, the original properties of the fiber can be retained while giving it excellent antibacterial properties. [0003]...
