摘要： The invention is to provide a base paper for a raising seedling pot and a raising seedling pot produced from the base paper, wherein while the base paper maintains a sufficient strength during raising seedlings and planting in the field, it is degraded over time by soil microorganisms after transplanting in the field and is produced by using a crosslinking agent that does not contain formaldehyde, resulting in a reduced burden on the environment; the base paper for a raising seedling pot, wherein a citric acid crosslinking agent, as a crosslinking agent for cellulose, is used in order to block the hydroxy group of cellulose in paper through crosslinking; and the raising seedling pot produced by molding and processing the base paper.

摘要： 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.

摘要： A novel method for strengthening and reinforcing ancient books is provided. Such treatment method comprises: first placing the ancient books to be treated in a closed strengthening and reinforcing device; after sealing, performing dehumidification operation and vacuumizing operation on system in sequence to maintain the system dry; and after the system is stable under negative pressure, turning on a fan set, directly delivering a strengthening and reinforcing powder to the strengthening and reinforcing device via a gas pipe, or atomizing a strengthening and reinforcing solution through a ultrasonic atomizer and then delivering the atomized solution to the strengthening and reinforcing device via the gas pipe, so that the ancient books to be treated absorb the strengthening and reinforcing agent sufficiently and evenly; and meanwhile monitoring pH value and humidity of the ancient books, thereby implementing strengthening and reinforcement of the ancient books.

摘要： The present invention relates to a medical nonwoven fabric comprising gelable cellulose derivative short-cut fibers as prepared by the paper making process, a preparation method thereof, and an adhesion prevention barrier using the same. The present invention provides a single phase of medical nonwoven fabric comprising gelable cellulose derivative short-cut fibers, to induce capillary action of micropores formed between the fibers and thereby control the gelation time, and provides a composite nonwoven fabric formed by laminating a nonwoven fabric layer comprising a different kind of biodegradable polymer material not susceptible to gelation on the single-phase of medical nonwoven fabric comprising gelable cellulose derivative short-cut fibers, thereby improving dimensional stability and convenience of surgical procedure. The present invention further provides a dyed medical nonwoven fabric to improve visibility, allowing easiness of recognizing the placement or location of the medical nonwoven fabric.
