Disclosed is a method for manufacturing an eco-friendly antibacterial coated paper. According to the method, an antibacterial coating agent is coated without releasing harmful substances to humans on the surface of a paper to ensure antibacterial activity. The antibacterial coating agent and the paper are easy to separate from each other to enable their recycling. The method enables the manufacture of a coated paper that has high antibacterial activity and waterproofness and is thus useful for surface coating of food. The method releases no volatile organic compounds. The coating components of the coated paper are not dissolved in water upon contact with water during use, causing no environmental problems and no harm to human health. In addition, the coating layer and the paper can be easily separated from each other after use, enabling the recycling of the paper.

A paperboard carrier suitable for use with textiles may include one or more strips of paperboard secured together to form a hollow tubular body, the body having an outer surface, and a coating covering some or all of the outer surface. The coating comprises a coating agent such as a silicon resin dispersed in a solvent such as isopropyl alcohol and little or no water. The coating may be applied to the outer surface by using a plurality spray nozzles arranged axially or circumferentially about the carrier.

Disclosed is a manufacturing process of intermittent coating release paper, which includes: a) undercoating; b) primary drying in a drying oven; c) printing optical marks; d) coating silicon in a section; e) accurately coating heat-sealing material on front and back sides of the base material; f) secondary drying, rolling up, the action of coating the silicon and coating the heat sealing material is precisely positioned by using the optical marks printed in the previous process. The manufactured release paper can be directly applied to the packaging of women's sanitary napkins, pads, and maternity napkins, there is no need to use spaced release paper, the whole can be degraded or recycled for pulping, and can also reduce the use of various coating materials during production, reduce production costs, thus being beneficial to improve the production level of the existing process and the ecological environment protection.

A cellulose-silicon oxide composite superhydrophobic material and a preparation method thereof are disclosed. In the method, cellulose substrates with different surface topographies are pretreated by a low-temperature plasma, and then a first silicon oxide layer is deposited on the cellulose substrate by a low-temperature plasma-enhanced chemical vapor deposition method, then modified by a low-temperature plasma, and finally a second silicon oxide layer is deposited thereon, thereby preparing a micro-nano structured superhydrophobic surface on the cellulose substrate, to obtain a cellulose-silicon oxide composite superhydrophobic material, which is an environmentally friendly bio-based hydrophobic material.
