Embodiment 1

[0031] Weigh 1g of chitin powder, dry in an oven at 105°C for 4 hours, and cool for later use. Use 100 mL of 0.3% (v / v) lactic acid, heat to 76° C. to dissolve 1 g of chitin powder, and filter to obtain a 1% (m / v) chitin solution. Weigh 2.97g of food-grade zinc lactate, dissolve it in 100mL of water, heat to 90°C, and dissolve it completely to obtain a 2.97% (m / v) zinc lactate solution. 1% chitin solution and 2.97% zinc lactate solution were mixed at 1:10. Add 1% (v / v) hydrophilic oil agent to obtain antibacterial agent. In the post-finishing process, the liquid rate of the non-woven fabric is 150% (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

[0033] 1kg of chitin powder, oven-dried at 105°C for 5 hours, cooled for later use. Use 100 L of 0.3% (v / v) lactic acid, heat to 90° C. to dissolve 1 kg of chitin powder, and filter to obtain a 1% (m / v) chitin solution. 59.4kg zinc lactate, dissolved in 1m 3 Heat it to 90°C in water to dissolve it completely, add 100L of prepared 1% chitin solution after cooling and mix evenly, add 10L of hydrophilic oil agent and mix evenly to obtain an antibacterial agent solution. Appropriately add a little essence to adjust the smell. In the post-finishing process, the liquid rate of the non-woven fabric is 50% (m / m) by padding method, and the antibacterial non-woven fabric is obtained by drying.

Embodiment 3

[0035] 1kg of chitin powder, oven-dried at 105°C for 6 hours, cooled for later use. Use 100 L of 0.3% (v / v) lactic acid, heat to 90° C. to dissolve 1 kg of chitin powder, and filter to obtain a 1% (m / v) chitin solution. 74.2kg zinc lactate, dissolved in 1m 3 Heat to 92°C in water to dissolve it completely, add 100L prepared 1% (m / v) chitin solution after cooling and mix evenly, add 10L water-repellent oil agent and mix evenly to obtain an antibacterial agent solution. 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 a preparation method of an anti-bacteria non-woven fabric and an antibacterial agent. The anti-bacteria non-woven fabric is prepared by comprising the steps of: dissolving chitosan by using lactic acid to prepare the chitosan solution; dissolving zinc lactate in deionized water to prepare the zinc lactate solution; mixing the chitosan solution with the zinc lactate solution to prepare the antibacterial agent; and modifying a non-woven fabric in an antibacterial way: adding the antibacterial agent on the non-woven fabric, drying to prepare the anti-bacteria non-woven fabric. According to the second part of antibacterial performance of fabrics in GB / T20944.2-2007, the anti-bacteria non-woven fabric prepared by the invention has bacterial inhibiting ratio more than 99 percent through absorptive method detection, is qualified through skin irritation and vagina mucosa irritation and skin allergic reaction irritation tests, and meets sanitation requirements on sanitation standard GB15980-1995 of disposable medical supplies and sanitation standard GB15979-2002 of disposable hygienic products.

Description

【Technical field】 [0001] The invention relates to an antibacterial nonwoven fabric and a manufacturing method of an antibacterial agent. 【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. [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 zinc nitrate; dilute acetic acid is used to dissolve chitosan sugar. Among them, zinc nitrate is corrosive. It decomposes at high temperature to produce irritating and highly toxic nitrogen oxide gas, which can cause poisoning if inhaled. Zinc chloride is very toxic and can severely irritate and burn the skin and mucous membranes. Zinc acetate is harmful to the environment, and it was mildly irritat...
