Ultraviolet-resistant fiber and production method thereof

Abstract

The invention discloses ultraviolet-resistant fiber which comprises fiber yarns, wherein the fiber yarns contain ultraviolet-resistant nano particles TiO2; and the ultraviolet protection factor (UPF) of the fiber yarns is greater than 50. A production method of the ultraviolet-resistant fiber, designed by the invention, comprises a section fusing step. The section fusing step comprises the following measure: polymerizing the ultraviolet-resistant nano particles TiO2 into polyester to form ultraviolet-resistant polyester sections, wherein the addition amount of the nano particles TiO2 accounts for 22.5% of the total weight of the ultraviolet-resistant polyester sections; and the particle diameter of the nano particles TiO2 is 50nm-80nm. The ultraviolet-resistant fiber obtained in the invention has the UPF greater than 50, is high in ultraviolet-resistant capability, can meet the life needs of people, simultaneously is good in favorable wool-like effect, has an ultraviolet-resistant function and simultaneously has the hand feeling and efficacy of wool. The production method of the ultraviolet-resistant fiber obtained in the invention is simpler in production process and can be generally used.

Description

Technical field [0001] The invention relates to a polyester fiber and a production method thereof, in particular to an anti-ultraviolet fiber and a production method thereof. Background technique [0002] The sunlight that reaches the ground is composed of ultraviolet rays, visible light, and infrared rays, of which ultraviolet rays account for 5%. It has been scientifically proven that excessive ultraviolet rays are harmful to human skin. People hope that their clothing can achieve good anti-ultraviolet effects. "Ultraviolet" function has also become a requirement for fabrics and polyester fibers. [0003] At present, there are few reports on UV resistant fibers in China. Usually ZnO and CeO are used in the production of anti-ultraviolet fiber 2 , SIO 2 Due to the production of anti-ultraviolet particles that meet people’s requirements, it is necessary to consider the variety, content and production process of anti-ultraviolet particles, and requires a lot of theoretical research...

AI Technical Summary

Problems solved by technology

Usually, ZnO and CeO are used in the production of anti-ultraviolet fiber 2 、SIO 2 Such as anti-ultraviolet particles, because the production of an anti-ultraviolet fiber that meets people's requirements needs to be considered from various aspects such as the variety, content, and production process of anti-ultraviolet particles, and requires a lot of theoretical research and practice, which is relatively difficult. Therefore, At present, the anti-ultraviolet ability of anti-ultraviolet fiber is generally poor, which brings inconvenience to people's life.
