Problems solved by technology

The main component of the non-woven fabric hydrophilic oil agent on the market today is the monofatty acid polyoxyethylene ester, which has the disadvantages of poor water solubility and low permeability when the EO number is low. When the EO number is high, the surface tension value is high and the wettability is also reduced.
Therefore, most of the non-woven fabric hydrophilic oil agents currently on the market cannot fully meet the needs of consumers.

Abstract

The invention belongs to the technical field of industrial surfactants, and particularly relates to a dicarboxylate-containing non-woven fabric hydrophilic oil agent as well as a preparation method and application thereof. The non-woven fabric hydrophilic oil agent containing the dicarboxylate is prepared from C21 dibasic acid polyoxyethylene ester, branched chain fatty alcohol-polyoxyethylene ether, Tween 80, PEG400 oleate, fatty alcohol-polyoxyethylene ether phosphate potassium salt and water. The preparation method comprises the following steps: adding the raw materials according to the ratio at different temperatures, fully stirring, adjusting the pH value of a sample in the stirring process, standing, sampling, testing the pH value, smell and appearance, and transferring into a sample bottle after being qualified. The dicarboxylate-containing non-woven fabric hydrophilic oil agent disclosed by the invention has the advantages of good hydrophilicity, high permeation block and no pollution to the environment, and is mainly applied to surface layer materials of baby diapers and the like.

Description

technical field [0001] The invention belongs to the technical field of industrial surfactants, and in particular relates to a non-woven hydrophilic and oily agent containing dicarboxylate and its preparation method and application. Background technique [0002] In recent years, with the continuous improvement of people's requirements for the comfort of baby diapers, the technology of diapers has also been continuously updated to meet the needs of the market. Non-woven fabrics are the first choice for the surface material of diapers due to their comfort, softness, and good air permeability. However, traditional non-woven fabrics have average hydrophilic properties, which can easily cause urine leakage or long-term contact with the baby's skin, resulting in poor comfort. Reduces or even triggers diaper rash. Therefore, the main function of the hydrophilic oil agent added in the non-woven fabric is to modify the hydrophobic surface into a hydrophilic surface. The main compone...
