▎ 摘 要
NOVELTY - Spinning solution comprises a cupro-ammonia spinning solution and an additive solution comprising 1,3-propanediol and graphene powder dissolved in 1,3-propanediol. USE - The spinning solution is used for preparing bacteriostatic copper ammonia fabric (claimed). ADVANTAGE - The spinnning solution has excellent antibacterial properties, increased strength of more than 30%, and greatly improves the performance of the fabric. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for preparing the spinning solution comprising (a) adding 1,3-propanediol into the first stirring vessel, adding graphene powder, and stirring evenly to obtain an additive liquid, and (b) adding the copper ammonia spinning solution to the second stirring vessel, and adding the additive solution, and stirring evenly to obtain the spinning solution; and (2) a method for preparing a bacteriostatic copper ammonia fabric comprising using the spinning solution in a spinning preparation process.
