I. New description: • ΓίΙΤΤΓΤ – 曰月曰 [New technical field] This creation is about an anti-fouling gauze and yarn, especially for a gauze containing C4-C5 fluorocarbon and its yarn structure. [Prior Art] At present, many construction openings are equipped with screen doors or screens. In addition to the original ventilation effect, it also has the advantage of preventing mosquitoes, dust, etc. from entering the room; and the screen door and screen window have evolved over the years. There are many types of use such as reel, cross-pull, split and concealed. In addition, there are many choices in the material of gauze or yarn, such as polyvinyl chloride (PVC), poly Ethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), stainless steel or iron wire; however, no matter how the evolution of the foregoing aspects and how the material changes, for the screen door or screen There is no gain in the antifouling effect, so that the commercially available screen doors or screens have not yet been provided with antifouling functions. The squirrel sold in the field can produce lower surface energy and has a good (four) force, so that the forest oil is contaminated with (four) to: more: stable::? and the price is only Only the pin is used on anti-fouling products. Perfluorinated compounds (PFCs) are predominantly used in the market, and perfluorochemicals refer to compounds in which the hydrogen in the carbon chain of the alkyl compound is completely replaced by fluorine, which has perfluoroalkyl sulfonic acids. And perfluorocarboxylic acid (perfluorocarboxylic acid), the most famous of which are perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA), but both are 8 carbon chain lengths ( C8) Perfluorocarbon structure. However, PFOS is a chemical substance that is difficult to decompose and easily accumulates in living organisms, and PFOS is distributed in the blood and liver when it enters the living body, and the stability of PFOS is very high, so it is difficult to be affected by living organisms. The metabolism is decomposed and discharged, and according to animal experiments, the organism contains 2 mg/kg of PFOS, which may lead to death. At present, the fluorine-based anti-fouling products that emphasize environmental protection in the Taiwan market are still dominated by 〇6 perfluorinated compounds and their derivatives. However, these fluorine anti-fouling products are prone to produce harmful components such as PFOA and PFOS during the synthesis reaction. 'And the C6 perfluorinated compound has a long half-life (can be as long as nearly 9 years), so the use of such products has problems such as polluting the environment and endangering human health; plus most of the screen doors or screens are located in the ventilated place. And it is also the place where people often touch when opening and closing the opening of the building. Therefore, based on the aforementioned human health and environmental protection issues, six perfluorocarbon compounds with a carbon chain length or longer are not suitable for use in yarns made of screen doors or screens. On the net and its yarn. Therefore, it is necessary to provide an anti-staining gauze and yarn and thread that does not pose a hazard to the human body and the environment, and to improve the current screen door or screen window without antifouling effect.
