Title of Invention\n\nBactericidal Cellulose Fibers  \n# 2.\n\nClaim  \nA fiber product containing bactericidal cellulose fibersor cellulose fibers of which a portion or all of the cationexchange groups of the cellulose fibers,which are dyed witha direct fluorescent dye containing anionic groups and whichhave a cation exchange capacity with a cation adsorptionparameter greater than 0.2,are bonded with silver ions,copper ions or zinc ions.  \n# 3.Detailed Description of the Invention\n\nThis invention relates to bactericidal cellulose fibers.  \nBactericidal fiber products are known in which minuteamounts of bactericidal compounds are attached to the fiberproduct.  However,because these compounds are not fixed tothe fibers,although they at first have a bactericidal effectthey have the drawback that they are washed out after l or 2washing so that a permanent bactericidal effect cannot beobtained.  Following that,they must be disinfected or abactericidal agent must be applied to them each time theyare used.  \nIt is also well known that silver ions,copper ions andzinc ions exhibit excellent bactericidal action against certaintypes of microorganisms.  Moreover,these bactericidal metalions have bactericidal effects in extremely minute amounts.Consequently,if extremely small amounts of bactericidal metalions can be supplied gradually,it would be possible to sustainbactericidal effects for a prolonged period.  \nThe inventors,taking note of the characteristics of thesebactericidal metal ions,conducted intensive studies on bondingbactericidal metal ions to cellulose fibers for the purpose ofobtaining cellulose fibers having permanent bactericidaiproperties.  As a result,they arrived at this invention.  \nSpecifically,this invention is a fiber product containingbactericial cellulose fibers or cellulose fibers of which aportion or all of the cation exchange groups of the cellulosefibers,which are dyed with a direct fluorescent dye containinganionic groups and which have a cation exchange capacity with acation exchange parameter greater than 0.2.are bonded withsilver ions,copper ions or zinc ions.  \nThe bactericidal metal ions,which are bonded to the anionicgroups present in the cation exchange fibers,are present in veryminute amounts on the surfaces of the fibers and gradually elute.As a result,the bactericidal fibers of this invention exhibitsuperior bactericial properties.  \nBy contrast,it is difficult to bond bactericidal metal ionsto ordinary cellulose fibers.  Moreover,the bonding strength isweak and the bactericidal metals easily drop off with the resultthat permanent bactericidal effects are not exhibited.  \nThe silver ions,copper ions and zinc ions serving as theanionic groups of cellulose fibers having cation exchangecapacity that are used in this invention should be bondedsubstances,for example,sulfonic acid groups,carboxyl groupsor hydroxyl groups.  Acidic groups such as sulfonic acid groupsand carboxyl groups are preferable.","cbCaih7DgRnRtV5O","https://ap.wps.com/l/cbCaih7DgRnRtV5O","pdf",738856,18,"English","# Title of Invention\n## Claim\n## Detailed Description of the Invention","[{\"question\":\"What is the core invention described in the patent?\",\"answer\":\"The invention is bactericidal cellulose fibers and fiber products in which bactericidal metal ions are bonded to cellulose fibers with cation exchange capability.\"},{\"question\":\"What conditions must the cellulose fibers meet?\",\"answer\":\"The fibers must have cation exchange groups dyed with a direct fluorescent dye containing anionic groups, with a cation adsorption parameter greater than 0.2.\"},{\"question\":\"Which bactericidal metal ions are bonded to the fibers?\",\"answer\":\"Silver ions, copper ions, or zinc ions are bonded to the cellulose fibers to provide bactericidal activity.\"}]","Bactericidal Cellulose Fibers - Patent Bureau of Japan Official Gazette for Unexamined Patents | PDF",1789965049,45]
