Filed: 2020-01-09
Abstract: The present invention relates to a banana non-woven fabric dedicated for cleaning oil, which is manufactured by using banana peel and waste paper. The banana peel is rich in a soft hydrophilic organic matter such as pectin, lignin, hemicellulose and protein to have a porous structure, and allows a hydroxyl group to have a function of better absorbing oil particles or ingrained dirt wherein the hydroxyl group is in cellulose within small granules encompassed by a fibrous membrane of an inner side of the banana peel. In addition, when the cellulose extracted from waste paper is mixed with ingredients extracted from the banana peel, a porous structure is further expanded as they are fiberized and a liquid, in particular an oily component, can be better absorbed. Accordingly, if a recycled non-woven fabric is manufactured using the banana peel and the waste paper, which are waste resources, the present invention is capable of recycling environmental waste and is easily available in eco-friendly kitchen towels with improved oil absorption and contamination removal of various lubricants like car oil stains.
