Embodiment 1

[0021] Embodiment 1: Under normal temperature and pressure, take 0.1% polyoxypropylene ether penetrating agent, 0.25% polymethacrylic acid emulsion binder, 0.07% methylsilane softening agent, 3% suspending agent according to weight percentage (by the following two A suspending agent is formed by mixing 2:1 by weight: hydroxymethyl cellulose, diatomaceous earth) and 93.98% water to prepare a solution. According to weight percentage, 0.1% organic antibacterial active component (by the following two kinds of organic antibacterial active components mixed with weight percentage 1: 2 forms: dimethyl didecyl ammonium chloride, 1,2-phenylpropylisothiazole- 3-ketone) and 2.5% inorganic antibacterial active components (nano-titanium dioxide) were added to the above solution, stirred rapidly for 1 hour, and then processed with a Nanomizer homogenizer at 3MPa for 1.5 hours to obtain a composite antibacterial finishing agent for textiles.

Embodiment 2

[0022] Example 2: At normal temperature and pressure, take 0.05% penetrating agent according to weight percentage (by mixing the following two penetrating agents according to weight percentage 1:1: polyoxypropylene ether, secondary octanol polyoxyethylene ether), 0.2 % polyacrylic acid emulsion binder, 0.5% silicone oil softener, 0.5% suspending agent (by mixing three kinds of suspending agents with a weight percentage of 1:1:2: gum arabic, tragacanth gum, polyvinylpyrrolidone ) and 96.25% water to prepare a solution. According to weight percentage, 2% organic antibacterial active component (polyamide clobendazole) and 0.5% inorganic antibacterial active component (by the following two kinds of inorganic active components mixed with weight percentage 1: 3: silver-loaded composite calcium oxide , silver-loaded zeolite) was added to the above solution, stirred rapidly for 1 hour, and then treated with a Nanomizer homogenizer at 7MPa for 3 hours to obtain a composite antibacteria...

Embodiment 3

[0023] Example 3: Under normal temperature and pressure, take 0.7% fatty alcohol polyoxypropylene ether penetrating agent, 1% acrylate and acrylonitrile copolymer emulsion binder, 0.3% methylsilane softener, and 0.3% suspending agent according to weight percentage (Sodium carboxymethyl cellulose) and 94.4% water to make a solution. According to weight percentage, 2.5% organic antibacterial active components (mixed by the following two organic antibacterial active components in a weight percentage of 1:3: quaternized ammonium silane, dimethyl didecyl ammonium chloride) and 0.8% inorganic The antibacterial active component (silver-loaded zirconium phosphate) was added to the above solution, stirred rapidly for 1 hour, and then treated with a Nanomizer homogenizer at 8.5 MPa for 3.5 hours to obtain a composite antibacterial finishing agent for textiles.

Abstract

The invention discloses a composite antibacterial textile finishing agent, which consists of the following components of: an organic antibacterial active ingredient, an inorganic antibacterial active ingredient, a penetrating agent, an adhesive, a softening agent, a suspending aid and water. A preparation method comprises the following steps of: dissolving the penetrating agent, the adhesive, the softening agent and the suspending aid into the water to prepare solution at normal temperature under normal pressure; adding the organic antibacterial active ingredient and the inorganic antibacterial active ingredient into the solution, and quickly stirring the solution; and treating the solution by using a Nanomizer high-pressure homogenizer to obtain the finishing agent. An application method comprises the following steps of: selecting pure cotton or blended fabric, soaking the pure cotton or the blended fabric into the composite antibacterial finishing agent, and soaking and rolling with an open width padder; and conveying the pure cotton or the blended fabric into a drying oven of 100 DEG C, pre-drying for 180 to 300 seconds, and conveying the pure cotton or the blended fabric to a drying oven of 120 DEG C for setting so as to obtain an antibacterial textile. The finishing agent plays a role in killing bacteria such as escherichia coli, staphylococcus aureus, candida albicans and the like; and the prepared textile has good antibacterial performance and durable antibacterial effect, the original wearing property of the textile is not changed, and the textile has good handfeel.

Description

(1) Technical field: [0001] The invention relates to a composite antibacterial textile finishing agent and its application, in particular to an antibacterial textile finishing agent based on an organic-inorganic composite antibacterial main material and processed by a Nanomizer high-pressure homogenizer and its application. (two) background technology: [0002] With the continuous improvement of people's living standards, the antibacterial problem has attracted more and more attention from all countries in the world, including my country. In real life, people will inevitably come into contact with various pathogenic microorganisms. Various textiles are a good place for these microorganisms to live and are also an important source of disease transmission. These pathogenic microorganisms will grow and multiply rapidly under suitable environmental conditions, and spread diseases and endanger human health through contact with humans. Therefore, antibacterial finishing of textil...
