preparation example Construction

[0038] A preparation method for a treatment agent for making soft paper towels, applied to the above-mentioned treatment agent for making soft paper towels, characterized in that it comprises the following steps:

[0039] Step S1: Mix the quaternary ammonium salt, alkyl phosphate ester or alkyl polyoxyethylene ether phosphate ester with monoglyceride, raise the temperature to 60-100°C, and gradually add it under high-speed stirring with a high-speed disperser water to obtain a transparent or translucent emulsion;

[0040] Step S2: lower the temperature to 50-60°C, and add glycerin therein under stirring;

[0041] Step S3: adding a surplus of water therein;

[0042] Step S4: adjusting the pH of the treatment to be between 3 and 8 with sodium hydroxide or potassium hydroxide or citric acid.

Embodiment 1

[0045] Mix 10g of glyceryl monostearate and 10g of dioctadecyltrimethylammonium chloride, raise the temperature to 80°C, start high-speed stirring of the high-speed dispersant, gradually add 80g of water to it, and continue stirring at high speed for 1 hour after adding water .

[0046] Cool down to 55°C, adjust the stirring speed to 60 rpm, add 750g of glycerin to it, stir well, then add 150g of water to it, adjust the pH of the treatment solution to 5.2, continue stirring for 0.5h, and then pack it.

Embodiment 2

[0048] Mix 15g of glyceryl monostearate and 50g of distearyl hydroxyethyl methyl ammonium methyl sulfate, raise the temperature to 70°C, start the high-speed dispersant and stir at high speed, gradually add 135g of water to it, and continue to high-speed after adding water Stir for 1h.

[0049] Cool down to 55°C, adjust the stirring speed to 60 rpm, add 700g of glycerin to it, stir well, then add 100g of water to it, adjust the pH of the treatment solution to 3.8, continue stirring for 0.5h, and then pack it.

Abstract

The invention discloses a treating agent for manufacturing soft tissues, which comprises the following components in percentage by weight: 60 to 85 percent of alcohol, particularly one or more of glycerol, propylene glycol, sorbitol and xylitol, wherein the glycerol accounts for not less than 60 percent of the treating agent; 0.1-3% by weight of fatty acid monoglyceride, wherein the fatty acid isone of a straight chain structure or a branched chain structure; 0 to 5% by weight of a quaternary ammonium salt; 0-5% by weight of at least one of alkyl phosphate or alkyl polyoxyethylene ether phosphate; and 10 to 40% by weight of water; wherein one of the quaternary ammonium salt and the alkyl phosphate is selected for use. The paper treated by the treatment agent has excellent softness and smoothness and good hydrophilicity; and (2) the influence of the hand feeling environment humidity of the paper treated by the treating agent is small.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a treatment agent for making soft paper towels and a preparation method thereof. Background technique [0002] In recent years, soft paper towels have become one of the fields with the fastest development and high added value in household paper. It has excellent hand feeling, with obvious softness, smoothness, fluffy feeling, no rough feeling, and the irritation to the skin is greatly reduced compared with ordinary paper towels. Compared with ordinary paper towels, soft paper towels have a higher moisture content, up to 10-25%; compared with wet paper towels, soft paper towels are in a non-wet state. Therefore, soft paper towels can be used the same as ordinary paper towels, but will give consumers a better experience. [0003] Chinese patent CN201210433789 discloses a surface-treated softener, which uses diorganosiloxane, monohydric or polyhydric alcohols, hydrophili...
