Pollution-proof mesh and yarn

Abstract

The invention provides a pollution-proof mesh and a yarn. The yarn undergoes a pre-treatment like a corona treatment or a plasma treatment or others to increase hydrophilcity of the outer surface of the yarn. As a secondary soaking in C4-C5 fluoride pollution-proof admixture under high temperature, the use safety of the pollution-proof mesh and the yarn can be ensured, fineness of yarns can be reduced, visual clarity of a screen window can be increased, and adhering property and adhering amount of the fluoride pollution-proof admixture can be improved, and the service lifetime of a screen window can be prolonged.

Description

technical field [0001] The present invention relates to an antifouling gauze and yarn, in particular to a 4 -C 5 Fluorine gauze and its yarn structure. Background technique [0002] At present, many openings of buildings are equipped with screen doors or screen windows. In addition to maintaining the original ventilation effect, it also has benefits such as preventing mosquitoes and dust from entering the room. Moreover, screen doors and screen windows have evolved over the years, and their types have scrolls. , horizontal pull type, split type and hidden type and other usage methods appear. In addition, there are also a variety of choices in the material of gauze or yarn, such as polyvinyl chloride (PVC), polyethylene ( PE), polypropylene (PP), polyethylene terephthalate (PET), stainless steel or iron wire, etc.; however, regardless of the evolution of the aforementioned methods and the changes in materials, the antifouling effect of screen doors or screen windows is not ...

Problems solved by technology

[0005] However, PFOS is a chemical substance that is difficult to decompose and easily accumulates in the body. Once PFOS enters the body, it will be distributed in the blood and liver. In addition, the stability of PFOS is very high, so it is difficult for the metabolism of the body. It is decomposed and excreted, and according to animal experiments, if the organism contains 2mg / kg of PFOS, it may cause death

At present, the fluorine anti-fouling products that emphasize environmental protection in the Taiwan market are still C 6 Perfluorinated compounds and their derivatives are mainly used, but these fluorine antifouling products are prone to produce harmful components such as PFOA and PFOS during the synthesis reaction process, and C 6 The half-life of perfluorinated compounds is also relatively long (up to nearly 9 years), so the use of such products actually has problems such as polluting the environment and endangering human health; It is a place that people often touch when opening and closing the openings of buildings. Therefore, based on the aforementioned human health and environmental protection issues, perfluorinated compounds with a carbon chain length of more than 6 are not suitable for use in screens and screens made of screen doors or screen windows. yarn on

[0006] Therefore, it is necessary to provide an antifouling gauze and yarn that do not pose a hazard to the human body and the environment, and to improve the current problem that screen doors or screen windows still do not have antifouling effects.
