Problems solved by technology

In the prior art, the luminescent powder is directly added as an additive to the polyester and then spun into filaments. The problem of poor dispersion of the luminescent powder in polyester is common, which leads to poor light storage effect and low strength of the fiber.
In order to obtain fibers with higher strength, high-strength stretching in the later stage is required, but it is difficult to directly obtain high-strength stretching of polyester fibers with luminescent powder, so it is necessary to obtain high-strength polyester filaments by using multi-stage stretching, but Since the product specification of high-strength polyester filament is usually greater than 550dtex, the production cost is higher if it is smaller than this specification, and it is usually drawn at high speed, the total number of drafting is only two levels, and the strength of self-luminous polyester high-strength filament is difficult to guarantee

Abstract

The invention discloses a polyester high-strength fishing net thread with self-luminous function and a preparation method thereof, comprising: compounding alkaline earth aluminate luminescent materials and alkaline earth silicate luminescent materials to obtain mixed luminescent powder; The powder self-luminous polyester masterbatch melt and ordinary polyester melt are mixed dynamically and statically to obtain a mixed melt containing low-concentration luminescent powder; by adjusting the spinning parameters, a large amorphous area and low crystallinity are produced. It is more suitable for self-luminous polyester FDY filaments of multi-stage drafting, and then low-speed, multi-stage drafting treatment. The polyester high-strength fishing net yarn with self-luminous function prepared by the present invention has a breaking strength of >6.5cN / dtex, a boiling water shrinkage rate of <4%, and can continue to glow in the dark for more than 12 hours after being fully illuminated.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyester high-strength fishing net yarn with self-luminous function and a preparation method thereof. Background technique [0002] In pelagic fisheries, fishing nets are usually used for one-time use. After fishing on the boat, the fishing nets are cut open, the fish in the nets are sorted and put into fish bins, and new fishing nets are replaced when the nets are lowered again. Most deep-sea fish have phototaxis. If the fishing net can emit weak light under the water surface, especially at night, it can attract more fish, greatly increase the fishing output of each net, and improve economic benefits. [0003] After absorbing all kinds of visible light for 10-20 minutes, the high-efficiency light-storing luminescent powder can continue to emit light in the dark for more than 12 hours, and has excellent low-light display and indication functions. In the prior art, t...
