Production method of spinning solution and tin oxide-based fiber for tin oxide-based fiber

摘要

PROBLEM TO BE SOLVED: To obtain the subject fiber not causing deformation of yarn shape by humidity in the atmosphere in spinning and/or after spinning by dissolving a tin compound, a metal compound and an alcohol-soluble metal compound into an alcohol to afford the spinning solution and spinning the solution. ;SOLUTION: This spinning solution comprises dissolving (A) an alcohol-soluble tin compound, (B) a metal tin and (C) an alcohol-soluble metal compound (metal is silicon, aluminum, germanium, titanium, zirconium, magnesium or boron) into an alcohol (preferably methyl alcohol or ethyl alcohol). The spinning solution is spun to produce the objective tin oxide fiber. Thereby, moisture resistance of gel fiber is remarkably improved.;COPYRIGHT: (C)1997,JPO
