<p>A cover cloth for outdoor use has the following layers in sequence from outer to inner: a waterproof plastic sheet, a nonwoven outer layer, a waterproof air-permeable membrane and a nonwoven inner layer. The waterproof plastic sheet includes a plurality of ventilation holes. The outermost layer is the waterproof plastic sheet, which is waterproof, air-permeable and sun-resistant so as to protect the inner layers from sun and rain. Thus, the lifespan of the cover cloth is prolonged. In addition, the waterproof plastic sheet has a smooth surface so that dirt adhered to the waterproof plastic sheet can be easily washed away.</p> |
