Embodiment 1

[0024] A preparation method of a general-purpose fabric antibacterial finishing agent, comprising the following steps:

[0025] (1) Grind and disperse Dendrobium dendrobium in water with a solid-liquid ratio of 1g:20mL, reflux at 80°C for 1 hour, filter, then add an organic solvent to the filtrate for layering, collect the organic layer, and dry it to obtain Dendrobium polysaccharide powder;

[0026] (2) Sodium alginate and sodium hydroxide solution with a mass concentration of 3% were mixed and stirred until the solid was dissolved, then the dendrobium polysaccharide powder prepared above was added, and after stirring and mixing, the temperature was slowly raised to 40° C., stirred for 1 hour at 3000 rpm, and then Cool to room temperature, filter, precipitate and dry to obtain sodium alginate cross-linked modified dendrobium polysaccharide; wherein, the dosage ratio of the sodium alginate and sodium hydroxide solution is 1g: 15mL; the sodium alginate and dendrobium polysaccha...

Embodiment 2

[0029] A preparation method of a general-purpose fabric antibacterial finishing agent, comprising the following steps:

[0030] (1) Grind and disperse Dendrobium dendrobium in water, the ratio of solid to liquid is 1g:40mL, reflux at 100°C for 5h, filter, then add organic solvent to the filtrate for layering treatment, collect the organic layer, dry, and obtain Dendrobium polysaccharide powder;

[0031] (2) Sodium alginate and sodium hydroxide solution with a mass concentration of 10% were mixed and stirred until the solid was dissolved, and then the dendrobium polysaccharide powder prepared above was added, and after stirring and mixing, the temperature was slowly raised to 60° C., stirred for 2 hours at 5000 rpm, and then Cool to room temperature, filter, precipitate and dry to obtain sodium alginate cross-linked modified dendrobium polysaccharide; wherein, the dosage ratio of the sodium alginate and sodium hydroxide solution is 1g: 35mL; the sodium alginate and dendrobium p...

Embodiment 3

[0034] A preparation method of a general-purpose fabric antibacterial finishing agent, comprising the following steps:

[0035] (1) Grind and disperse Dendrobium dendrobium in water with a solid-liquid ratio of 1g:25mL, reflux at 80°C for 2h, filter, then add an organic solvent to the filtrate for layering, collect the organic layer, and dry it to obtain Dendrobium polysaccharide powder;

[0036] (2) Sodium alginate and sodium hydroxide solution with a mass concentration of 5% were mixed and stirred until the solid was dissolved, then the dendrobium polysaccharide powder prepared above was added, and after stirring and mixing, the temperature was slowly raised to 45°C, and stirred at 3500pm for 1.5h, Then cool to room temperature, filter, precipitate and dry to obtain sodium alginate cross-linked modified dendrobium polysaccharide; wherein, the dosage ratio of the sodium alginate and sodium hydroxide solution is 1g:20mL; the sodium alginate and dendrobium polysaccharide The m...

Abstract

The invention discloses a preparation method of a universal fabric antibacterial finishing agent. The preparation method particularly includes following steps: using dendrobium as a raw material, andextracting to obtain dendrobium polysaccharide; preparing sodium alginate crosslinked modified dendrobium polysaccharide; dispersing the sodium alginate crosslinked modified dendrobium polysaccharidein deionized water; sequentially adding acrylic resin, chitosan, silane coupling agent, defoamer and thickener, and stirring and mixing well to obtain the antibacterial finishing agent. The finishingagent is high in stability and fabric wettability and capable of effectively improving antibacterial performance and mechanical performance of fabric.

Description

Technical field: [0001] The invention relates to the field of textile auxiliaries, in particular to a preparation method of a general antibacterial fabric finishing agent. Background technique: [0002] Due to its microporous structure, textiles have long been considered by hygienists to be the most suitable breeding grounds for microorganisms such as bacteria and fungi. The body temperature of the wearer, the moisture emitted by the human body, and the metabolites of the skin have further enhanced the vitality of the germs and microorganisms remaining on the fabric. Due to the characteristics of water repellency and low moisture absorption of the fiber itself, synthetic fibers have a certain inhibitory effect on the survival and reproduction of microorganisms. The keratin components in protein fibers and the sugar in cotton fibers can be used as nutrients for most microorganisms under suitable conditions. Soil, electrolytes secreted by the human body, and some finishing a...
