Problems solved by technology

However, the addition of these ultraviolet agents is relatively large, and the increase in the addition will definitely affect its spinnability; in addition, the fibers contain some metal compounds such as lead and antimony, which will also cause certain damage to the human body.

example 1

[0025] Master batch formula: the mass fraction of nano-titanium nitride in the compound is 10%, the mass fraction of titanate is 2%, the white oil is 2%, and the mass fraction of polyester chip is 86% of the compound. Nano-titanium nitride, titanate, white oil and polyester chips are mixed, and the anti-ultraviolet masterbatch is made through melt extrusion, pelletizing, drying and other processes. The anti-ultraviolet masterbatch and polyester chips are mixed at a ratio of 1:19, and then the nano-titanium nitride anti-ultraviolet fiber is obtained through a conventional melt spinning process. Take the 100d / 48f nano-titanium nitride anti-ultraviolet polyester fiber as an example, the average ultraviolet shielding rate of the polyester fiber is 93%.

example 2

[0027] Master batch formula: the mass fraction of nano-titanium nitride in the composite is 6%, the titanate is 1.2%, the white oil is 1.8%, and the polyester chip is 91% of the composite. Nano-titanium nitride, titanate, white oil and polyester chips are mixed, and the anti-ultraviolet masterbatch is made through melt extrusion, pelletizing, drying and other processes. The anti-ultraviolet masterbatch and polyester chips are mixed at a ratio of 1:11, and then the nano-titanium nitride anti-ultraviolet fiber is obtained through a conventional melt spinning process. Take the 100d / 48f nano titanium nitride anti-ultraviolet polyester fiber as an example, the average ultraviolet shielding rate of the polyester fiber is 89%.

example 3

[0029] Master batch formula: the mass fraction of nano-titanium nitride in the compound is 18%, the mass fraction of titanate is 1.8%, the white oil is 1.2%, and the mass fraction of polyester chip is 79% of the compound. Nano-titanium nitride, titanate, white oil and polyester chips are mixed, and the anti-ultraviolet masterbatch is made through melt extrusion, pelletizing, drying and other processes. The anti-ultraviolet masterbatch and polyester chips are mixed at a ratio of 1:9, and then the nano-titanium nitride anti-ultraviolet fiber is obtained through a conventional melt spinning process. Take the 100d / 48f nano-titanium nitride anti-ultraviolet polyester fiber as an example, the average ultraviolet shielding rate of the polyester fiber is 90%.

Abstract

The invention discloses a nano-titanium nitride anti-ultraviolet polyester fiber. The fiber contains nano-titanium nitride with a concentration of 0.5%-2% by weight and has an anti-ultraviolet function. The fiber is made of nano-titanium nitride, other additives and carriers to make a masterbatch, and the masterbatch is added to polyester chips and melt-spun. The addition of nano-titanium nitride makes the polyester fiber have good anti-ultraviolet function; and does not affect its spinnability; the average ultraviolet shielding rate of the spun anti-ultraviolet functional polyester fiber is above 85%; at the same time, it does not affect people's health. Nano-titanium nitride anti-ultraviolet polyester fiber can be widely used in outerwear, sportswear, trousers and other fields.

Description

technical field [0001] The invention relates to the field of functional fibers, in particular to a polyester fiber containing nano-titanium nitride and having an anti-ultraviolet function. Background technique [0002] With the extensive use of freon worldwide and the increasing environmental pollution, the ozone layer in the atmosphere has been seriously damaged. Long-term exposure to ultraviolet radiation will reduce the lifespan of organic molecules and reduce the immune function of the human body. It will not only damage the skin and cause dermatitis, erythema, freckles and skin cancer, but also promote eye diseases and cataract diseases. Ultraviolet rays can be divided into three regions according to their wavelengths, and the wavelength of UVA in the near ultraviolet region is 400-320nm. The wavelength of UVB in the middle ultraviolet region is 320-290nm, and the wavelength of UVC in the far ultraviolet region is 290-200nm. Among them, UVC is absorbed by the ozone la...
