A luminescent yarn and a manufacturing method thereof. The luminescent yarn is a multilayered structure, a cross-section of the yarn includes a main body and at least one luminescent surface layer having multiple luminescent particles and positioned on at least one surface of the main body. Accordingly, the luminescent surface layer is positioned on the surface of the luminescent yarn to directly absorb energy and emit luminescence, whereby the luminescent yarn has better luminance and longer luminescence-emitting time. The manufacturing method of the luminescent yarn includes steps of: manufacturing a film material, the film material having a substrate material and at least one luminescent layer disposed on at least one surface of the substrate material; and cutting the film material to form the luminescent yarn.

Disclosed are methods of extracting an enzyme, comprising soaking a seed in an aqueous solution, homogenizing the seed to produce a homogenized suspension, and filtering the homogenized suspension to produce a crude extract, wherein the crude extract comprises urease and non-urease proteins.

The invention provides a filament, which is a fine filament cut and formed from a thermoplastic membrane material, and is made by thermal stretching and thermal shaping. Through the invention, the filament formed by cutting can have excellent physical properties including: high strength, high elastic recovery rate, low stretch elasticity, low elongation rate, improved environmental tolerance, and increased service life, so that the filament formed by cutting has a wider application range and can be directly used in textiles. The invention is capable of producing filaments thinner than those obtained by cutting method alone. In addition, when a surface of the filament is coated with a functional coating layer, the filament of the invention will not lose the function of the coating layer.

According to the present invention, there is provided, at low cost, a thread/yarn for making it possible to easily determine whether a product is a genuine product or a forgery/imitation product, thereby suppressing the manufacture and marketing of forgery/imitation products. This forgery-preventing thread/yarn is formed by making use of a film comprising abase sheet and letters or images printed on the base sheet, the film being slit to have a width of 0.15 mm˜0.75 mm. A thread, yarn or a flat thread representing a genuine product can be cheaply manufactured since it can be obtained by simply slitting a film to a width of 0.15 mm˜0.75 mm. Further, it is possible to easily determine whether a product is a genuine product or a forgery/imitation.

Disclosed are a method for preparing spun leather yarn using leather fiber, and spun leather yarn prepared according to the preparation method. The spun leather yarn prepared according to the preparation method enables the manufacture of fabrics, knitted goods, and lace goods, which have the character of leather, and thus can be effectively used for various fashion applications. In addition, the spun leather yarn can replace existing leather materials, which have been used in bags, athletic shoes, and the like, and thus is not affected by material supply in accordance with seasonal changes, and accordingly, the economic effect thereof is excellent. Moreover, the spun leather yarn has warmth retention and general flame retardancy, which are the properties of natural leather, and thus is of very high quality.
