The invention discloses a high-performance multiple azo brown reactive dye. The reactive dye comprises the multiple azo reactive dyes shown by a formula I. The reactive dye is used for dip dyeing, continuous dyeing and printing on protein fibers such as fur, silk and the like or cellulosic fibers such as cotton, flax and the like, the color ranges from yellow light brown to dark brown, and the high-performance multiple azo brown reactive dye not only has higher dye absorptivity and fixation rate, but also has strong such wet-processing fastness as being washable and sweat proof as well as light fastness. The monogenetic dye does not have the defects of head-tail difference and edge-center difference.

The invention belongs to the technical field of preparation of fibers, and relates to a functional viscose fiber for producing silicate minerals and acid and salt amphoteric matters, in particular to a viscose fiber containing an adhesive short fiber and an adhesive filament for eliminating bad smell of perspiration and a preparation method thereof. The viscose fiber for eliminating bad smell of perspiration comprises a chitin fiber and a deodorant, wherein the weight percentage content of the chitin fiber is 92.5-98 percent; the deodorant is an aluminum silicate mineral inorganic deodorant, and is less than or equal to 1 mum in average particle diameter; the chitin fiber or cellulose comprises an adhesive short fiber and an adhesive filament; the dry fracture strength of the adhesive short fiber is more than 2.23cN / dtex, and the wet strength is more than 1.05cN / dtex; the dry fracture strength of the adhesive filament is more than 1.7cn / dtex, and the wet strength is more than 0.84cn / dtex; and the ammonia gas reducing rate can be more than or equal to 75 percent, the acetic acid reducing rate can be more than or equal to 80 percent, and the isopentanoic acid reducing rate is more than or equal to 85 percent. The preparation method comprises the following steps of: mixing a nano-grade deodorant with a high-concentration cellulose adhesive to obtain a blended spinning solution; spinning and molding a blend fiber through a coagulation bath; and desulfurizing, washing with water and drying to obtain the viscose fiber for eliminating bad smell of perspiration. A product has the advantages of high deodorizing performance, no side effects, simple preparation process, reliable principle, easiness and convenience in operating, saving in energy sources, environment friendliness and remarkable economic benefit.

The invention relates to an automatic electric generator which supplies power to electric appliances by using strings to provide power to push a magnet to work. The electric generator is formed by combining a motor, a sensor, a power accumulator, a rectifier, a winding, a power transmission device, a lead, a switch, a driving wheel, and a power device, a transmission device, a reinforcement device, a reduction gear, a generator, and an upper chord device which are matched with the generator. The invention which can replace the prior coal-fuelled generator, fuel generator, wind power generator, water power generator and the like has the advantages that the generator is free from pollution and noises, requires no energy, can continuously work for a long time, is convenient to carry and widein application, and saves time, labor, and money.

The invention provides a preparation method of carbon quantum dots based on a chemical reaction of fructose and sodium hydroxide, and belongs to the technical field of nanomaterials. The method comprises a first step of preparing a D-fructose solution; a second step of preparing a sodium hydroxide solution; a third step of mixing the D-fructose solution with sodium hydroxide solution; and a fourth step of standing the mixed solution to obtain a carbon quantum dot solution.
