摘要： Provided is a high-performance PVA fiber and its production.Each filament of the PVA fiber of the present invention having a structure comprising an aggregate of substantially innumerable fibrils, the fiber has high strength, elastic modulus, and resistances to fatigue, hot water and chemicals and can be pulpified while keeping its excellent features such as high strength. The PVA fiber of the present invention cannot, even drawn to a high ratio, be readily whitened by virtue of its fibril-aggregate structure, and can hence be made still higher in performances. The PVA fiber can be obtained by adding to a PVA solution a relatively large amount of surface active agent, and wet or dry-jet-wet spinning the thus prepared dope solution into an aqueous alkaline coagulating bath.

摘要： A water-absorbing laminate comprising a water-absorbing film and a non-woven fabric, in which the water-absorbing film is formed by film-forming a mixture of (A) a water-soluble polymer containing, as the monomer component, at least 40 mole % of an .alpha.,.beta.-unsaturated compound containing one or two carboxyl groups or groups from which a carboxyl group can be easily derived and in which 5% to 50% of the carboxyl groups and/or groups from which a carboxyl group can be easily derived are in the form of a salt, and (B) polyvinyl alcohol in a weight ratio of (A)/(B) of not less than 1/99 to less than 1/9. This water-absorbing can be produced by laminating the water-absorbing film on the non-woven fabric under pressure either in a hydrous and heat-softened state of the film or through an adhesive and, optionally, heat-treating the resultant laminate.This water-absorbing laminate can avoid the formation of excessive moisture and prevent waterdrops from dropping while keeping the heat-retaining properties, when used as a sheet for a cover culture. As a result, the occurrence of disease in the plants under culture and any reduction in the yield and quality of the plants are effectively prevented.

摘要： A water absorbing composite comprises an inorganic powder, and a highly absorbent resin covering the whole surfaces of the individual particles of the inorganic powder. The resin is obtained by reacting with a basic substance a polymer containing as a monomeric constituent an .alpha.,.beta.-unsaturated compound having in its molecule one or two carboxyl groups, or one or two other groups convertible to a carboxyl group or groups, and by crosslinking the reaction product with a polyamine. The composite is useful as a water retaining agent for agriculture and horticulture, or as a dehydrating agent for oil.
