Description

Technical Field

[0001] The utility model relates to the technical field of PTFE fiber structures, and in particular to a tensile-resistant PTFE fiber structure. Background Art

[0002] Polytetrafluoroethylene (PTFE) fiber, also known as fluorine or teflon, is a polyolefin fiber made from polytetrafluoroethylene (PTFE) through spinning or film formation followed by cutting or fibrillation. It offers high strength and elongation, excellent chemical stability, and superior corrosion resistance to other synthetic fibers. Its surface has a waxy feel and a low coefficient of friction. Its actual operating temperature is -180°C to 260°C, with strength significantly decreasing when heated to 300°C. It exhibits good weather resistance and flexural resistance. However, it suffers from poor dyeability, thermal conductivity, and abrasion resistance, a high coefficient of expansion, and is prone to static electricity generation. It is primarily used in high-temperature dust filter belts, filter media for highly corrosive gases or liquids, valve packing, sealing tape, self-lubricating bearings, rocket launch pad linings, artificial blood vessels, and military outerwear. Production methods include emulsion spinning, paste extrusion spinning, and melt spinning.

[0003] Although polytetrafluoroethylene fibers have better strength when woven into fabrics, the tensile strength of the fabric is not improved. The woven fabric is easily stretched and deformed, which affects the use of the fabric. The deformation of the fabric also leads to a decrease in its other properties. Therefore, a tensile-resistant PTFE fiber structure is needed to solve the above problems. Utility Model Content

The button 1 can press the slide 501 to make it slide in the sliding mouth 7. The other end of the slide 501 is connected to a conical seat 502. The outer wall of the conical seat 502 is overlapped with the plug 9.
