Title:
レーヨン練り込み用液晶乳化型エマルションの作製方法及びレーヨン繊維
Document Type and Number:
Japanese Patent JP7357353
Kind Code:
B2
Abstract:
To provide a method for producing a liquid crystal emulsion type emulsion for kneading rayon for producing a rayon fiber containing a water-soluble functional substance which has been unable to be produced by a method for producing a rayon fiber containing an oil component (water-insoluble functional substance).SOLUTION: In the method for producing a liquid crystal emulsion type emulsion for kneading rayon containing a water-soluble functional substance, water is added dropwise to a mixture of a water-soluble functional substance and a nonionic surfactant to prepare a liquid crystal emulsion mixture, and a polar silicone oil is added dropwise to the liquid crystal emulsion mixture to prepare a liquid crystal emulsion technical product; water is added dropwise to the liquid crystal emulsion technical product to prepare an O/W type liquid crystal emulsion type emulsion for kneading rayon having an appropriate viscosity.SELECTED DRAWING: None
