Development and use of birth origin Teflon PTFE is very dramatic, and many inventions often come from accidents. DuPont Roy Plunkett is a very good example 1250D PTFE sewing thread, when you try to create a new CFC refrigerants in 1938, accidentally discovered polymerized tetrafluoroethylene high pressure storage vessel, followed by the 1941 made its patent and in 1944 with "Teflon" The name of the registered trademark. It also gradually appear teflon in people's lives provides a start. Production and living weapons and military technology, is the existence of a Teflon PTFE sewing thread, which also shows the great achievements after Teflon appear achieved. Structural requirements structural features PTFE sewing thread sewing thread, is the uniformity of the morphology, the quality and continuity of the integral use of PTFE sewing thread distribution, and the stability of the interaction between the fibers. Despite the fancy sewing thread, deformation lines, Internet yarn does not satisfy the requirements of this three paragraphs in the local, but the overall macro-characteristics must meet these three properties. And three of the fundamental decisions are a state of the fiber, pile density and interaction between the fibers. The first two is the sewing thread structure; the latter is linked structure between the units, depending on the characters of the fiber surface. 1, reflecting the characteristics of the fiber pile sewing thread bulk density; 2, expression of fiber orientation because of the twist angle back PTFE sewing thread filament fiber, or due to deformation of the fibers and curled conformation, bulky, elastic elongation parameters. 3, reflecting the multi-strand twisted and multi-root of the number of repeated twisting, twisting direction parameter. 4, reflecting the appearance of sewing thread diameter and thickness and diameter variation coefficient of variation, or sewing quality and uniformity of the line density is not uniform. The new report on the market situation PTFE research; new industry report Teflon PTFE production data and new data reporting industry sales; new Teflon reporting enterprise market share and brand share, the new Teflon report predict the future prospects of the industry. This study reports data mainly through market research, the National Bureau of Statistics, the National Customs Information Center data, as well as journals and online information second-hand information of desktop studies. National Bureau of Statistics data available which includes industry data and enterprise data; national customs information center including import and export data; coupled with the company's own research team to conduct market research, price data mainly from the various market monitoring data.
