Fibre and fabric with ultraviolet screening effect

Abstract

The present invention provides a fibre with ultraviolet shading effect, and is characterized by that in the fibre an inorganic titanium dioxide particles whose average grain size is less than 100 nm is added, and its added quantity is less than 1% of weight of fibre to obtain said fibre, said invention also provides the fabric made up by using said fibre with ultraviolet shading effect, and the weight of said fibre is above 50% of total weight of the fabric, and when the open area ratio of said fabric is greater than 0.7% and less than 25%, the UPF (ultraviolet protection factor) is greater than 40%.

Description

technical field [0001] The present invention relates to fibers and fabrics with ultraviolet shielding effects, especially the fibers obtained by adding 1% by weight or less of inorganic titanium dioxide microparticles with an average particle diameter of less than 100 nanometers (nm) in the fibers to have ultraviolet shielding effects, and using The fabric made of the fiber with ultraviolet shielding effect; the weight of the fiber with ultraviolet shielding effect accounts for more than 50% of the total weight of the fabric, and when the opening ratio of the fabric is greater than 0.7% and less than 25%, the UPF (Ultraviolet Protection Factor) is higher than 40 %. Background technique [0002] Recently, due to the large increase in outdoor activities, the market demand for fabrics with UV shielding effects, especially sportswear, golf wear, fishing wear, uniforms, hats, parasols and curtains, has increased significantly. [0003] In order to develop fibers and fabrics with...

Problems solved by technology

[0009] The techniques for improving the UV shielding properties of fibers disclosed in the aforementioned three Japanese patent publications are achieved by adding at least 1% by weight, or even as high as 40%, of metal compounds with UV reflective or absorbing properties, but when a large amount When the metal compound is added to the fiber, in addition to the problems of poor spinning productivity, reduced fiber strength and yellowing of the fiber color, and because a large amount of metal compound is dispersed on the surface of the fiber, the fiber is used in weaving, dyeing and finishing in the later stage. During the processing process, it is very easy to cause the thread path of the processing machine to wear, which is not good for the quality of the product, and the service life of the processing machine is greatly shortened, which increases the manufacturing cost.
