Permanently-uvioresistant light fabric

Abstract

The invention provides permanently-uvioresistant light fabric which comprises warp and weft. At least one of the warp and the weft is of complete-extinction polyester yarn with flat cross sections, and plains of the polyester yarn face to the front side of the fabric. By the arrangement, configuration of traditional uvioresistant fabric is broken through, the complete-extinction polyester yarn is adopted, shielding performance of the fabric is enhanced, titanium dioxide added into the yarn during initial extinction treatment is also a shielding agent for ultraviolet rays, penetration of the ultraviolet rays can be reduced, reflection performance of the ultraviolet rays can be further enhanced by the aid of the flat cross sections, the fabric itself is remarkably capable of resisting the ultraviolet rays under the conditions that the shielding agent for the ultraviolet rays is not used during the dyeing and finishing process and processes like coating are not performed, the fabric is unaffected by washing times, and permanent uvioresistant performance is achieved; therefore, the permanently-uvioresistant light fabric is stable and endurable in uvioresistant effect, novel and reasonable in structure and highly practical.

Description

technical field [0001] The invention relates to the field of textile products, in particular to a permanent anti-ultraviolet light and thin fabric. Background technique [0002] Longing for nature and being close to nature, people increasingly realize that the natural world is also a comfortable, convenient and happy living space, not just the idyllic scenery depicted in postcards. Consumers in the future want to actively get close to nature, and nature has opened up a new consumer market for businesses, because it has increasingly become an ideal place for adventure, exploration, and sports. This just needs clothes fabric to have frivolous, fashion sense, especially have excellent anti-ultraviolet property. [0003] From the perspective of optics, when light hits an object, part of it is reflected on the surface, part is absorbed by the object, and the rest passes through the object. In general, transmittance + reflectivity + absorptivity = 100%. Therefore, the higher the...

AI Technical Summary

Problems solved by technology

These inorganic materials with UV shielding function are non-toxic, odorless, non-irritating, good thermal stability, non-decomposing, non-volatile, and good UV shielding properties, such as benzophenone compounds, benzotriazoles, etc. , salicylic acid compounds, organic nickel polymers, triazines and other organic anti-ultraviolet classes, but to add these materials in the dyeing and finishing process, specific processing methods must be used, such as adding these inorganic materials to the coating, but for 25D / 72F, fine denier products, the strength of the coated fabric is difficult to meet the requirements, there are certain disadvantages

Dipping processing method, separate exhaust method processing, because the fabric is very light and thin, the absorption of anti-ultraviolet shielding agents is poor, and there is also an environmental impact

The most important thing is that the aforementioned methods are difficult to achieve the durability of UV resistance
