good water adsorptivity andwater retention capability which is characterized by thefact that it is perforated nonwoven cloth of which l to 50%of the total surface area is occupied by fine pores with amean pore diameter of 0.05-10 mm and where a water-absorbingresin layer is applied to the surface of the fibers thatcomprise the nonwoven cloth,and by the fact that the weightratio of nonwoven cloth and water absorbing resin is 100:1to 1:10 in a dry state.  \n(2)  A method for manufacturing nonwoven cloth withgood water absorptivity and water retention capability whichis characterized by the fact that perforated nonwoven clothof which 1-508 of the total surface area is occupied byfine pores with a mean pore diameter of 0.05 to 10 mm istreated with a cross-linking agent and a water soluble oraqueous polymer solution that can form a water absorbingresin with said cross-linking agent and is then cross-linked.  \n(3)  The manufacturing method in item 2 of Claims wherethe cross-linking agent is a compound that contains 2 ormore epoxy groups or amino groups in its molecules and thewater soluble or aqueous polymer is a reaction product of ananhydrous maleic acid copolymer and basic substance.  \nDigitized by the Internet Archivein 2016  \nhttps://archive.org/details/nonwovenclothwit00miya  \n# Detailed Explanation of Invention\n\nThis invention pertains to a nonwoven cloth that showsgood water absorptivity and water retention capability andis soft and air permeable and a method for its manufacture.The purpose of this invention is to present a material thatis suitable for various uses.  \nIt is a known fact that nonwoven cloth is made into awater absorbing material with water retention capabilityusing a powder or solution of a water absorbing resin.However,there are disadvantages with the former in thatwhen used for clothing,the product is not resistant tobending and the powdered resin peels from the cloth.  On theother hand,there are disadvantages with nonwoven cloth thatis coated with the latter water absorbing resin in thatalthough the resin that is used improves durability of thecloth,it markedly reduces air permeability as the nonwovencloth becomes hard.  \nThis invention solves the above-mentioned problems.  Itis a perforated nonwoven cloth where fine pores with a meanpore diameter of 0.05 to 10 mm,preferably 0.2 to 5 mm,occupy 1-508,preferably 2 to 30%of the total surface areaand a water absorbing resin layer is applied to the surfaceof the fibers that comprise the nonwoven cloth.  It presentsa nonwoven cloth with good water absorptivity and waterretention capability that is characterized by the fact thatthe weight ratio of nonwoven cloth and water absorbing resinlayer is 100:1 to 1:10 in a dry state.  In addition,this  \ninvention also is a method for manufacturing nonwoven clothwith good water absorptivity and wa","cbCaisEKikFT2zUn","https://ap.wps.com/l/cbCaisEKikFT2zUn","pdf",570260,22,"English","# TRANSLATION\n## Detailed Explanation of Invention\n## Specification\n## Title of Invention","[{\"question\":\"What is the core material described in this patent?\",\"answer\":\"The patent describes a perforated nonwoven cloth with fine pores and a water-absorbing resin layer applied to the fiber surface to achieve both water absorptivity and water retention.\"},{\"question\":\"How does the described structure improve performance?\",\"answer\":\"Fine pores increase the resin’s surface area and help maintain softness and air permeability, while the resin is retained better during bending compared with powder-based approaches.\"},{\"question\":\"What does the manufacturing method involve?\",\"answer\":\"A perforated nonwoven cloth is treated with a cross-linking agent and a water-soluble or aqueous polymer solution that can form the water-absorbing resin, and then the components are cross-linked.\"}]","NONWOVEN CLOTH WITH GOOD WATER ABSORPTIVITY AND WATER RETENTION CAPABILITY - Specification | PDF",1789963296,55]
