Problems solved by technology

Traditional zinc glycinate has poor solubility, and zinc lactate can be dissolved in water when heated, but when the concentration of its aqueous solution reaches 3%, it will crystallize out
Therefore, the traditional zinc ion antibacterial agent has a low zinc ion concentration and a high liquid rate, mostly 80-120%, which cannot meet the production needs of high-speed nonwovens production lines

Embodiment 1

[0022] Weigh 10g of zinc glycinate powder, weigh 6g of zinc lactate powder, dissolve in 100mL of deionized water after mixing, heat to 90°C to dissolve them all, and the content of zinc glycinate is 10% (m / v), and the content of zinc lactate It is a 6% (m / v) zinc glycinate-zinc lactate complex solution. Add 0.1% (v / v) hydrophilic oil agent to get antibacterial agent. In the post-finishing process, the liquid rate of the non-woven fabric is 15% (m / m) by padding method, and the antibacterial non-woven fabric is obtained by drying. In the upper liquid rate, m / m means the ratio of mass to mass, which refers to the ratio of the mass of the antibacterial agent to the mass of the cloth.

Embodiment 2

[0024] Weigh 50kg zinc glycinate powder, weigh 30kg zinc lactate powder, mix and dissolve in 1m 3 Heat it to 90°C in deionized water to dissolve it completely, and prepare a zinc glycinate-zinc lactate complex solution with a zinc glycinate content of 5% (m / v) and a zinc lactate content of 3% (m / v). Add 10L hydrophilic oil agent and mix well to obtain antibacterial agent. Appropriately add a little essence to adjust the smell. In the post-finishing process, the liquid rate of the non-woven fabric is 30% (m / m) by padding method, and the antibacterial non-woven fabric is obtained by drying.

Embodiment 3

[0026] Weigh 100kg zinc glycinate powder, weigh 60kg zinc lactate powder, dissolve in 1m after mixing 3 Heat it to 85°C in deionized water to dissolve it completely, and prepare a zinc glycinate-zinc lactate complex solution with a zinc glycinate content of 10% (m / v) and a zinc lactate content of 6% (m / v). Add 10L hydrophobic oil agent and mix well to obtain antibacterial agent. In the post-finishing process, the liquid rate of the non-woven fabric is 10% (m / m) by spraying method, and the antibacterial non-woven fabric is obtained by drying.

Abstract

The invention discloses an antibacterial agent and a preparation method of an antibacterial nonwoven cloth, and the preparation method of the antibacterial nonwoven cloth comprises the following steps: preparing a zinc glycinate-zinc lactate complex solution by dissolving zinc glycinate and zinc lactate in deionized water; preparing the antibacterial agent by mixing the zinc glycinate-zinc lactate complex solution with a surface-active agent, and performing antibacterial modification on the nonwoven cloth by adding the antibacterial agent to the nonwoven cloth and drying, thus obtaining the antibacterial nonwoven cloth. The antibacterial nonwoven cloth is detected according to Part 2: Absorption Method of GB / T20944.2-2007 Textiles-Evaluation for Antibacterial Activity, the bacterial inhibitory rate is greater than 99 percent, and the experimental strains are Escherichia coli, staphylococcus aureus and Candida albicans; and the antibacterial nonwoven cloth meets the sanitary requirements of GB15979-2002 Hygienic Standard for Disposable Sanitary Products and GB15980-1995 Hygienic Standard of Disinfection for Single Use Medical Products.

Description

technical field [0001] The invention relates to an antibacterial agent and a method for manufacturing an antibacterial nonwoven fabric. Background technique [0002] At present, there are many kinds of antibacterial nonwovens, and many products only pursue their antibacterial effect, while ignoring their harm to human body and environment. The most commonly used metal ions for antimicrobial agents include silver, zinc, and copper ions. The cost of silver ion antibacterial agent is relatively high, and there is a potential risk of oxidation and blackening. "Technical Requirements for Ecological Textiles" GB / T18885-2009 and "General and Special Technical Requirements for Ecological Textiles" Oeko-Tex100 have strict limits on copper ions. [0003] In the Chinese patent application "Preparation Method of Chitosan / Zinc Composite Antibacterial Agent" with publication number CN100360035C, the divalent zinc ions come from hydrated zinc sulfate, zinc acetate, zinc chloride, and zin...
