One aspect of the present invention, prepared by stirring a wet strength agent, a naturally derived surfactant, citric acid and purified water at 1 to 4% by weight: 8 to 38% by weight: 1 to 4% by weight: 60 to 90% by weight, respectively It provides a method for preparing a detergent coating composition having a cleaning function and increasing the wettability of phosphorus and paper.

The wet strength enhancer refers to an additive added to improve wet strength, which means the strength of paper in a state where it is saturated with water. It is divided into permanent wet strength enhancers that do not.

In one embodiment, the wet strength enhancing agent may be at least one wet strength enhancing agent selected from the group consisting of polyamideamine epichlorohydrin, melamine resin, urea resin, and glyoxylated polyacrylamide resin.

The surfactant refers to a substance that can act at an interface where water and oil do not mix with each other, and is mainly used in soaps and detergents because of the property that water and oil can be mixed well.

Naturally derived surfactants refer to surfactants obtained through natural products, and include alkyl polyglucosides, which are naturally derived surfactants extracted from coconut, palm, sugar cane, corn, wheat, etc. There are sodium cocoyl apple amino acid made by reaction, and potassium cocoate made from coconut oil and potassium hydroxide.

In one embodiment, the naturally-derived surfactant may be at least one naturally-derived surfactant selected from the group consisting of alkylpolyglucoside, cocoglucoside, decylglucoside, sodium cocoylapple amino acid, and potassium cocoate.

The naturally-derived surfactant can be used with nonionic surfactants, anionic surfactants, cationic surfactants, and amphoteric surfactants, including environmentally certified dishwashing detergents from the Ministry of Environment, but can cause skin irritation and skin damage during the washing process. In order to minimize the use of naturally derived surfactants, priority is given.

The citric acid is a weak organic acid contained in various citrus fruits and vegetables, and is used as a food additive by giving a sour taste, and is also used as an eco-friendly detergent or disinfectant because of its sterilization effect. Specifically, citric acid in the present invention may be used as an environmentally friendly detergent additive and an additive that improves the effect of a wet strength enhancer by adjusting pH at the same time.

The lavender is known to have antiseptic and cell regeneration promoting effects, mugwort is effective for allergic skin, and green tea contains a large amount of vitamins and components such as catechin, tocopherol, and tannin to enhance skin elasticity, soothe, and whiten It is known to be effective in sterilization, moisturizing, etc., and ginkgo biloba is known to be effective in improving skin aging.

As described above, it is possible to provide a detergent coating composition effective for the skin by adding an ingredient effective for skin soothing, skin regeneration and skin improvement as an additive.

If the weight % of the detergent coating composition is significantly different from the above, the effect of improving wet paper power or detergency may be reduced. Specifically, when the wet strength enhancer is less than 1%, the effect of improving the wet strength may be insignificant, and when it exceeds 4%, the wet strength improvement effect is low compared to the amount of the wet strength enhancer, so the economical efficiency is low. In addition, if the surfactant is less than 8%, the cleaning effect may be insignificant, and if it exceeds 38%, the unit price of the cleaning coating solution prepared through this may increase.

Another aspect of the present invention is to coat or impregnate the detergent coating liquid composition prepared by the above manufacturing method on natural pulp paper, dry it, and then cut it with a plastic blade knife or cut it with sawtooth, in the form of a roll with cut lines at regular intervals, or one by one. It provides a method for manufacturing a paper scrubber with improved wetness and cleaning function, which is manufactured by processing and packaging in the form of tissue to be pulled out, individual packaging for one sheet, and sheet form.

First, after preparing paper base paper weighing 20 to 120 g per 1 square meter with a dense structure in a coating machine capable of drying, the paper is passed through several rolls to move up and down in the coating liquid container containing the detergent coating liquid composition prepared by the above manufacturing method. The paper is coated or impregnated with the detergent coating solution so that it is sufficiently wetted from front to back using a roll.

Next, the coated or impregnated paper is passed through a drying zone equipped with hot air of 70 ° C. to 150 ° C. or UV, IR drying, etc., and finally, after drying with natural wind or cold air, the paper is wound in a roll form.

Next, after embossing to increase the detergency of the rolled paper roll, a roll type that is cut with a plastic blade knife or cut with sawtooth according to the purpose, a roll type with cut lines at regular intervals, or a tissue type that is used by pulling out one sheet, 1 It is cut and packaged in the form of individual packaging for each sheet and in the form of a sheet.
