Abstract: A method for chemical fibrillation of silk and silk paper manufactured by the same are provided to recycle waste silk unusable for clothes, by treating the waste silk chemically and producing the silk paper using the treated waste silk. A process for chemical fibrillation of silk is performed by treating silk fibroin with a mixed solution of sodium hydroxide and sodium carbonate. In the mixed solution, the sodium hydroxide has a concentration of 0.2-2 vol%, and the sodium carbonate has a concentration of 2-5 vol%. The process for chemical fibrillation of silk is performed at a temperature of 70-100°C for 20-80 minutes.

Abstract: PURPOSE: A method for the enzyme hydrolysis of sericine and a reactor used therefor are provided, therefore the high purity, low molecular weight sericine can be obtained and used enzyme can be reused, so that the low molecular weight sericine can be cheaply obtained. CONSTITUTION: The method for the enzyme hydrolysis of sericine comprises the steps of: partially hydrolyzing a fiber to expose hydroxyl group (-OH) and carboxyl group(-COOH) on the surface of the fiber; activating the surface of the fiber using a cross-linking agent; fixing an enzyme on the activated surface of the fiber; loading the fiber in two separate enzyme reactors; and circulating a sericine solution into the enzyme reactors to decompose the sericine, in which the fiber is polyester or nylon, the cross-linking agent is glutaraldehyde, and the enzyme is trypsin or alpha-chymotrypsin(wherein, the trypsin is fixed on a first enzyme reactor and the alpha-chymotrypsin is fixed on a second enzyme reactor).

Abstract: A method for fibrillation of mulberry branches, silk paper containing mulberry fibers, and a method for manufacturing the silk paper are provided to prevent environmental pollution and recycle resources, by producing the silk paper from a mixture of mulberry fibers and waste silk. Endodermis of mulberry is smoothened and decolorized by using at least one, which is selected from hydrogen peroxide, sodium sulfate-disodium peroxodisulphate mixture, sodium silicate, and sodium silicate-hydrogen peroxide mixture. The treated endodermis of mulberry is divided into fibers. The hydrogen peroxide has a concentration of no more than 2 vol%, the sodium sulfate-disodium peroxodisulphate mixture has a concentration of 1-2 wt%, the sodium silicate has a concentration of no more than 2 wt%, and the sodium silicate-hydrogen peroxide mixture has a concentration of 1-1.5 vol%. Further, the step of smoothening and decolorizing Endodermis of mulberry is performed for 30 to 120 minutes at 70 to 100°C.
