Embodiment 1

[0031] The preparation method of the anti-ultraviolet fabric of the present invention comprises yarn preparation, weaving, dyeing, anti-ultraviolet finishing, setting, fluffing, softening on a setting rolling machine, and post-finishing.

[0032]1) The anti-ultraviolet fiber is used in the yarn preparation process. The anti-ultraviolet fiber is modified ceramic particles with high-efficiency shielding ultraviolet rays, dried, added to the polymerization kettle, and produced after esterification and polycondensation. Polyester finally obtains anti-ultraviolet polyester yarn by spinning; factors such as acid and alkali impregnation affect the use effect); among them, the ceramic particles are selected as aluminum nitride, and the ceramic powder is obtained by liquid phase grinding, with a size of 50-500nm. Dispersion in polymerized monomers, using ethylene glycol polymers to modify the surface of ceramic particles, the addition ratio of modifiers is 3% according to the mass rati...

Embodiment 2

[0042] The preparation method of the anti-ultraviolet fabric of the present invention comprises yarn preparation, weaving, dyeing, anti-ultraviolet finishing, setting, fluffing, softening on a setting rolling machine, and post-finishing.

[0043] 1) The anti-ultraviolet fiber is used in the yarn preparation process. The anti-ultraviolet fiber is modified ceramic particles with high-efficiency shielding ultraviolet rays, dried, added to the polymerization kettle, and produced after esterification and polycondensation. Polyester finally obtains anti-ultraviolet polyester yarn by spinning; factors such as acid and alkali impregnation affect the use effect); among them, the ceramic particles are selected from silicon nitride, and the ceramic powders are obtained by gas phase grinding, with a size of 50-500nm. The ground ceramic particles are chemically modified to improve their performance in polyester polymerization. Dispersion in the monomer, using a polymer of propylene glycol ...

Abstract

The invention discloses a preparation method for an uvioresistant fabric and the uvioresistant fabric. The method comprises the steps that uvioresistant fiber is prepared, wherein ceramic particles with the function of efficiently shielding ultraviolet ray and polymers containing hydroxyl are mixed for surface modification and drying, after the esterification and polycondensation reactions, polyester with the uvioresistant effect is prepared, and the uvioresistant is obtained through spinning; the uvioresistant fiber is subjected to weaving and dyeing by using dye; an uvioresistant finishing agent is prepared. According to the long-lasting uvioresistant fabric, the uvioresistant effect of products can be significantly improved, the initial ultraviolet penetration rate is less than or equalto 0.5%, the ultraviolet protection coefficient can reach UPF50+, after the fabric is washed twenty times, the ultraviolet penetration rate is less than or equal to 1.5%, the ultraviolet protection coefficient can still reach UPF50+, and the fabric further has a good infrared absorption function.

Description

technical field [0001] The invention belongs to the technical field of fabric production, and in particular relates to a preparation method of an anti-ultraviolet fabric and an anti-ultraviolet fabric. Background technique [0002] With the continuous development of science and technology and the continuous strengthening of human self-protection awareness, people have clearly realized that the skin is a weak link of the human body. The channel is therefore a line of defense that must be paid attention to. In recent years, the incidence of skin diseases has been increasing. The research results show that moderate exposure to ultraviolet rays is beneficial to human health, but excessive exposure to ultraviolet rays will cause some damage. Among them, when UVC passes through the atmosphere, it can be absorbed by the ozone layer 25km away from the ground and will not reach the ground; most of UVB is absorbed by the dermis of the skin, which promotes the denaturation of nucleic ...
