Description

Manufacturing method of clean PU foam and pads {Manufacturing method PVA polyurethane foam and clean pad}

The present invention relates to a manufacturing method of the PUB polyurethane foam clean pad and a clean pad thereof, and more specifically, to remove dust and foreign matters caught on the floor of an office building, and to be used as a pad of a manual cleaner. The use of foam-based clean pads prevents the wear of rubbed cement floors with large coefficients of motion friction. A polyurethane foam clean pad manufacturing method and a clean pad thereof.

Generally, when cleaning the living room and the floor of the home, you may use only a normal clean pad (also called "cleaning bag") to clean the floor. Manual cleaners with hand bars and clean pad mounting plates connected by universal joints can be used to wipe them off.

Clean pads used by being mounted on the clean pad mounting plate of the manual cleaner have been produced in various forms by various materials.

Currently, the clean pad used in the hand cleaner uses a pad mainly composed of cotton.

Cotton clean pads do not have much friction against the floor, so cleaning can be done without much effort to clean them.However, when the moisture is contained, the weight is transferred to the wrist. It has the disadvantage of going to the body.

In addition, cotton material has no adsorptive power, so it is hard to wipe off dirt or hair dirt on the floor, and the wiped dirt falls on the floor again.

In addition, it has a disadvantage that the use of rinsing water is increased because the drainage is not good when it is sucked and reused during use, and the use of rinsing water is large. When it is used in this insufficient place, it is often reused before it is dried.

As described above, the clean pad made of cotton is the same phenomenon when used as a general cleaning pad as well as a manual cleaner.

Therefore, in recent years, the ability to remove foreign matters is excellent, and the adsorption power to adhere to the removed foreign matters is good, and the drainage is excellent, and at the same time, a lot of light weight materials are used cellulose fiber.

Cellulose fibers have the above-mentioned advantages, while the adsorption force that makes foreign matters stick together has a dual property that causes adsorption to the floor, which requires a lot of force when scrubbing the floor. It was in the state which was not easy to use as a pad.

In addition, the cellulose fiber is not removed by the entire surface facing each other when the cleaning by pushing the bottom surface due to the adsorptive force, foreign matter is removed only in the tip portion that is pushed to move.

The reason is that the adsorption force is also the adsorption force, but no void cells are formed on the surface of the cellulose fibers facing the bottom.

Therefore, the applicant of this case patented a clean pad made of cellulose fiber, which has cellulose fiber as the main material, which has excellent advantages, and can easily slip against the bottom surface of the object to be cleaned, and foreign matter is evenly deposited on the entire floor. It was developed as 10-2007-0119446.

The present invention complements and develops a clean pad based on cellulose fibers, which is a prior invention, and its purpose is to provide a PUB polyurethane that can be used as a pad of a manual cleaner when wiping dust and foreign matters caught on the floor of an office building. A method of manufacturing a foam clean pad and a clean pad thereof are provided.
