Benefits of technology

The scouring pad described in this patent has the following benefits: it cleans well, is easy to use, doesn't damage surfaces, and breaks down naturally in the environment.

Problems solved by technology

When such a scouring pad is manufactured of a synthetic polymer fiber, a problem of environmental pollution caused by processing a waste polymer during disposal may occur.
However, conventional scouring pads manufactured using an environment-friendly polymer generally either have lower detergency or do not make foam well.
Also, such products may cause scratches on the surface of a cleaning target such as a dish.

examples

[0046]Filaments and monofilaments were manufactured by spinning a PLA fiber extracted from corn. Afterward, the filaments and monofilaments formed of 100% PLA were woven to be a scouring pad (size: 200 mm×200 mm) including a net and an edge sewing line through a spinning process. Details for the scouring pad manufactured according to the Example are shown in Table 1.

Description

TECHNICAL FIELD[0001]The present disclosure relates to a scouring pad, and more particularly, to a scouring pad which is environment-friendly and has higher detergency. The present disclosure is directed to providing an environment-friendly scouring pad which has excellent cleaning performance, easily makes foam, and does not cause any scratches on a surface.BACKGROUND[0002]Generally, scouring pads are widely used to remove scraps on dishes and the like. When such a scouring pad is manufactured of a synthetic polymer fiber, a problem of environmental pollution caused by processing a waste polymer during disposal may occur. Because of the problem, scouring pads manufactured using an environment-friendly polymer are being developed.[0003]However, conventional scouring pads manufactured using an environment-friendly polymer generally either have lower detergency or do not make foam well. Also, such products may cause scratches on the surface of a cleaning target such as a dish.SUMMARY ...
