Embodiment 1

[0019] Embodiment 1: with the consumption of 0.01mol / L, silver acetate is joined in the polyvinyl alcohol solution of 0.3% with the mass percent concentration, adjusts pH to be 1, then adds the zinc phosphate powder (average particle diameter 1 -10 microns), control the silver-zinc ion mol ratio to be 1: 15, stir for 5 hours in a water bath at 30 degrees centigrade, and place the product after suction filtration and drying under high-temperature conditions of 650 degrees centigrade to roast for 2 hours to obtain an antibacterial agent for textiles.

Embodiment 2

[0020] Embodiment 2: with the consumption of 0.007mol / L, silver nitrate is joined in the hydroxymethyl cellulose solution that mass percent concentration is 0.1%, and the pH value of adjustment is 3, then adds the zinc phosphate powder (average particle size) after jet milling 1-10 microns in diameter), control the molar ratio of silver and zinc ions to 1:10, stir in a water bath at 45 degrees centigrade for 3 hours, filter the product and dry it, and then bake it at a high temperature of 500 degrees Celsius for 1 hour to obtain an antibacterial agent for textiles.

Embodiment 3

[0021] Embodiment 3: with the consumption of 0.025mol / L, silver acetate is joined in the polyvinylpyrrolidone solution that mass percent concentration is 0.08%, adjusts pH to be 5, then adds the zinc phosphate powder (average particle diameter) after airflow pulverization 1-10 microns), control the molar ratio of silver and zinc ions to 1:7, stir in a water bath at 30 degrees Celsius for 4 hours, filter the product after drying, and place it in a high temperature condition of 450 degrees Celsius to roast for 2.5 hours to obtain an antibacterial agent for textiles.

Abstract

The invention discloses an antibacterial agent for textiles. The antibacterial agent is characterized by comprising composite crystal of zinc phosphate and silver phosphate. A preparation method comprises the following steps of: adding soluble silver salt into macromolecular protective solution, and adjusting the pH value to be between 1 and 7; adding zinc phosphate powder; stirring in a water bath; and roasting the dried product at a high temperature to obtain the antibacterial agent for textiles. An application method comprises the following steps of: adding the antibacterial agent for textiles into water containing adhesive, stirring, and treating the solution through a Nanomizer high-pressure homogenizer to prepare finishing working solution; and selecting pure cotton or blended fabric, soaking the pure cotton or the blended fabric into the working solution, soaking and rolling with an open width padder, and conveying the pure cotton or the blended fabric to a drying oven for setting so as to obtain an antibacterial textile. The mixed crystal structure enables silver ions to be well protected in the crystal structure of the laminar zinc phosphate, so that the stability of the mixed crystal structure is greatly improved, and the antibacterial durability of the mixed crystal structure is greatly enhanced; the preparation method is simple, convenient and feasible, and is easy to reach the requirement of industrialized production; and the antibacterial agent is easily attached to the textiles, so the antibacterial agent achieves long-acting antibacterial property.

Description

(1) Technical field: [0001] The invention relates to a textile antibacterial agent and its preparation and application, in particular to a textile antibacterial agent composed of zinc phosphate and silver phosphate composite crystals and its preparation and application after being treated with a Nanomizer high-pressure homogenizer. (two) background technology: [0002] All kinds of textiles used in people's daily life are a good living place for various pathogenic microorganisms and an important source of disease transmission. These microorganisms will grow and reproduce rapidly under suitable conditions, and spread diseases through contact and affect human physical and mental health. After years of research, people have developed a variety of technologies for antibacterial treatment of textiles, such as: antibacterial textiles made of chitosan fibers and cotton fibers blended with chitosan fibers disclosed in the published CN1858316A patent literature; Chinese invention pat...
