Title:

絹及び絹様材料の繊維、フィルム及び不織布の製造方法、並びに、それらの方法によって製造された繊維、フィルム又は不織布

Document Type and Number:

Japanese Patent JP3972092

Kind Code:

B2

Abstract:

To provide a method for producing a fiber, a film or a nonwoven fabric composed of silk and/or a silky material without causing a reduction of molecular weight.

The method for producing the silk fiber or the silky fiber comprises carrying out spinning from a solution prepared by dissolving silk fibroin and/or the silky material in a hexafluoroacetone hydrate therein and, as necessary, drawing the resultant fiber. The method for producing the silk film or silky film comprises casting the solution obtained by dissolving the silk fibroin and/or silky material in the hexafluoroacetone hydrate therein, drying the cast film and, as necessary, stretching the dried film. The method for producing the nonwoven fabric composed of ultrafine fibers of the silk fibroin and/or silky material comprises carrying out electrospinning of the solution. The fiber, film or nonwoven fabric is composed of the silk fibroin and/or silky material obtained by the method.
