Luminous high-strength polyester industrial yarn and preparing method thereof

Abstract

The invention discloses a luminous high-strength polyester industrial yarn. The luminous high-strength polyester industrial yarn comprises raw materials including, by mass, 14-16 parts of a pigment, 14-16 parts of a polymerizable dispersant, 0.8-1.2 parts of an anionic surfactant, 9-11 parts of deionized water, 0.65-0.85 part of a comonomer and 0.014-0.016 part of an initiator. The luminous high-strength polyester industrial yarn has the advantages that rare earth luminous gel is prepared first, the gel and a polyester substrate are subjected to blending, melt spinning, two-stage drafting, two-stage slacking, heat setting and then winding and forming, the uneven dispersing problem of an inorganic rare earth material and polyester chips is solved, the evenly-dyed and excellent-color-fastness luminous high-strength polyester industrial yarn is obtained, meanwhile the luminous yarn can automatically absorb sunlight energy and can present various colors under the sun or in the dark, and the time limit of the luminous effect is long.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a luminous high-strength polyester industrial yarn and a preparation method thereof. Background technique [0002] Luminous fiber is a non-toxic, harmless, non-radioactive, and recyclable functional fiber. Its biggest feature is its excellent afterglow performance. The fiber is generally based on polyester, nylon or polypropylene, using long-lasting rare earth aluminate as the luminous body, adding nano-scale additives, and is a luminous fiber made by special spinning technology. The luminescence of the rare earth luminous fiber is due to the transition of the 4f electrons in the inner layer of the rare earth particles in the f-f configuration or between the f-d configurations, thereby generating absorption and emission spectra. When light illuminates the rare earth luminous fiber, the 4f electrons in the inner layer of the rare earth ion absorb light and transition from the gr...

Problems solved by technology

[0003] The rare earth luminous fibers currently developed are mainly surface coating methods. Although the products obtained by this method can emit light to varying degrees at night, the disadvantages are that the products are not washable and have poor friction resistance. feature disappears
