Problems solved by technology

The main reason for limiting the application of chlorine dioxide is its instability, easy to decompose when heated or exposed to light, the aqueous solution can only be stored for 8 hours at room temperature, and it is difficult to store for a long time
The slow-release chlorine dioxide products currently in use on the market have defects of varying degrees, such as short validity periods, unstable release volume, and difficulty in controlling the release rate, etc.

Embodiment 1

[0033] The preparation of embodiment 1 degradable non-woven fabric for disinfection

[0034] Both the water-absorbent resin and the nonwoven fabric in the specific application examples of the present invention are commercially available.

[0035] Mix 72wt% of powdery sodium alginate water-absorbing resin, 2wt% of sodium chlorite, 0.5wt% of solid fragrance, and 5wt% of citric acid. It is sprayed on the chitosan non-woven fabric after being melted at a temperature of ℃.

Embodiment 2

[0036] The preparation of embodiment 2 degradable nonwovens for disinfection

[0037] Mix powdered chitosan water-absorbent resin 88wt%, sodium chlorite 0.5wt%, solid fragrance 2wt%, sodium bisulfate 10wt%, grind evenly after mixing, the water content of all materials does not exceed 0.5wt%, and then evenly distribute On the chitosan nonwoven fabric; another piece of chitosan nonwoven fabric coated with a formaldehyde-free alcohol-soluble polyurethane adhesive is covered on this piece of fabric, which is rolled and bonded to form a composite nonwoven fabric.

Embodiment 3

[0038] Example 3 Disinfectant wet wipes made of degradable non-woven fabric for disinfection

[0039] Spray clear water evenly on the degradable non-woven fabric for disinfection manufactured in Example 1, 2-6ml on every gram of non-woven fabric, get ready to use.

Abstract

The invention relates to a degradable non-woven fabric for disinfection, in particular to a degradable non-woven fabric capable of releasing chlorine dioxide when meeting water, and a preparation method thereof. The degradable non-woven fabric for disinfection is compounded by degradable absorbent resin and a degradable non-woven fabric; and the absorbent resin is mixed with chlorite and solid acid, and can release the chlorine dioxide with disinfection effect when meeting water. The degradable non-woven fabric for disinfection can be widely used for civil or medical disinfection products, has good disinfection effect, and has the effect of promoting a wound to heal. Besides, the degradable non-woven fabric for disinfection is prepared from biodegradable materials, the preparation process is simple, the cost is low and the environment is protected.

Description

technical field [0001] The invention relates to a degradable non-woven fabric for disinfection and a preparation method thereof, in particular to a degradable non-woven fabric capable of releasing chlorine dioxide upon contact with water and a preparation method thereof. Background technique [0002] Wet wipes have become one of the necessary cleaning products for people. However, most of the traditional wet wipes are based on non-woven fabrics made of polyethylene, polypropylene, polyester and polyamide. Although the cost is low, its largest The disadvantage is that it is neither biodegradable nor recyclable, and a large amount of use will cause white pollution. In addition, in order to manufacture functional wet wipes, it is necessary to prepare solutions containing many chemical components, which are easy to pollute water sources. With the enhancement of people's awareness of environmental protection, the use of biodegradable materials to manufacture environmentally frie...
