The superfine poly- lactic acid type fiber, the fiber structure and the poly- lactic acid component which

摘要

At electrostatic spinning method the spinning doing the solution which makes with the reduction union of L- lactic acid and the reduction union of D- lactic acid melt, you obtain the fiber structure. Quite, at the same time it possesses small fiber diameter, it possesses the heat resistance which is superior and it is possible to offer the fiber structure which includes the fiber which possesses biodegradation characteristic.
