Cleaning method: Use neutral detergent to clean, and dry with a soft brush. Paper cloth products are washable paper cloth products. Many people hear that paper can be washed, and intuitively think of what coating is added to make the paper waterproof? The raw materials of paper cloth and paper come from bark. Generally, paper will make bark into pulp, while paper cloth is long fiber that retains bark, knead the long fiber into paper thread, then weave into paper cloth, and then cut, sew, etc. Steps to complete various products. Because it retains the long fibers of the bark, the paper cloth is tougher than traditional paper, and has the advantages of being washable, breathable, quick-drying, and not easily moldy. The raw materials for paper cloth come from FSC certified afforestation trees, which can be naturally decomposed and can be recycled and reused. I hope more people can use paper cloth as an environmentally friendly material.
