Problems solved by technology

Yet the graft rate of above-mentioned grafting reaction, and this wet tissue still needs to be further improved on antibacterial property, softness and pungency
[0008] In order to solve the problems of antibacterial properties, poor softness and irritation of wet wipes in the prior art, the present invention provides a kind of non-woven fabric wet wipes grafted with acrylic acid bisquaternary ammonium salt, which acts as a positively charged antimicrobial membrane Or particles and negatively charged microbial cell membranes produce electrostatic force, which causes microbial cell membranes to rupture or change in shape, resulting in the death of microorganisms, thus having antiseptic and antibacterial capabilities. Allergies, especially suitable for allergic skin, tender skin, etc.

preparation example 1

[0045] 1) Dry hydrogen chloride gas is introduced into the anhydrous ether solution of octadecyl dimethyl tertiary amine to produce a white precipitate. Then use water as the solvent, put epichlorohydrin in the dropping funnel, start to drop slowly, drop it in 35 minutes, stir evenly at room temperature, react at 80°C for 12h, and measure the content of epichlorohydrin quaternary ammonium salt by titration Determine the end point of the reaction. After the reaction is complete, remove the solvent by rotary evaporation at room temperature to obtain a light yellow paste residue, recrystallize the paste residue with acetone, and filter under reduced pressure after the crystals are precipitated. Repeat this several times to finally obtain a white powder. Monoquaternary ammonium salt product - intermediate product N-(3-chloro-2-hydroxypropyl)-N,N-dimethyloctadecyl ammonium chloride. Wherein, the mol ratio of octadecyl dimethyl tertiary amine: hydrogen chloride: epichlorohydrin is 1...

preparation example 2

[0056] Identical to Preparation Example 1, the difference is only: in the 1) step, use the anhydrous ether solution of dodecyl dimethyl tertiary amine, finally obtain the biquaternary ammonium salt B described in the following formula.

[0057]

Embodiment 1

[0059] The preparation method of the wet wipe body is as follows:

[0060] (1) Using bamboo pulp fibers with a length of 50 mm and a diameter of 0.08 mm as raw materials, a bamboo pulp non-woven fabric is obtained after cross-lapping and spunlace technology, and a non-woven fabric carrier with a thickness of 4 mm is obtained after cutting and high-temperature sterilization ;

[0061] (2) Place the non-woven fabric carrier prepared in step (1) in the monomer solution prepared by 1L isopropanol / water mixed solvent, and soak for 24 hours in the dark at room temperature; the monomer is diquaternary ammonium salt A and Potassium hydroxide neutralization degree is 65% acrylic acid, the mass fraction of bisquaternary ammonium salt A in the monomer solution is 0.1%, and the molar ratio of bisquaternary ammonium salt A and (acrylic acid+acrylic acid salt) is 25: 1. The volume ratio of isopropanol to water is 3:1;

[0062] (3) Under nitrogen protection, add CeCl to the monomer solutio...

Abstract

The invention discloses acrylic acid biquaternary ammonium salt grafted non-woven fabric wet tissue which comprises a wet tissue body and wet tissue liquid, wherein the wet tissue body selects nonwoven cloth of an antimicrobial film or a nanoparticle with positive charge; the antimicrobial film or the nanoparticle is formed by chemical bond combination; wet tissue liquid selects RO purified water,12-18 alkyl glucoside, lecithin or hydrogenated Lecithin, 1,2-pentanediol, a skin conditioner, and other additives; and 0.1-1.0mg / L of ozone is introduced into the wet tissue liquid; and finally, the wet tissue liquid is added into the wet tissue body in certain weight ratio, and is sealed and packaged to form the acid biquaternary ammonium salt grafted non-woven fabric wet tissue. The product belongs to the wet tissue which does not separate out preservative, is soft on skin, is free of stimulus and irritability, and is especially suitable for sensitive skin, tender skin and the like.

Description

technical field [0001] The invention relates to a non-woven fabric wet tissue grafted with acrylic acid diquaternary ammonium salt, in particular to a napkin wet tissue for infants. Background technique [0002] In recent years, because the application of wet wipes has brought convenience to people's lives and has gradually become a necessity in people's lives, the annual output and consumption of wet wipes have grown rapidly, and the application fields of wet wipes have continued to expand , the corresponding product development requirements are getting higher and higher. At present, there are many types of wet wipes, such as hand and mouth wipes, sanitary wipes, makeup remover wipes, skin cleansing wipes, etc. With the continuous expansion of the market scale, the national industrial policy encourages the wet wipe industry to move towards high-tech and high value-added The development of product direction will improve product competitiveness and market share, so the devel...
