Analysis of the relevant advantages of polyurethane material thermal fuse
Polyurethane material thermal fuse has high compressive strength. Short fibers are at the center of 2.6~5.7cn/dtex, while high-strength chemical fibers are at the center of 5.6~8.0cn/dtex. It has low water absorption, and its wet compressive strength and dry compressive strength are basically the same. The impact force is 4 times that of polyester and 20 times that of viscose fiber.
Ductility properties of polyurethane material thermal fuse. Wool has high ductility and is basically modified when stretched by 5% to 6%. The anti-aging properties are better than other chemical fibers, that is, they do not wrinkle and the condition is stable. In the range of 22~141cn/dtex, the elastic mold is 2~3 times that of acrylic resin.
Among man-made fibers, polyurethane material thermal fuse has the best temperature resistance and heat resistance.
The surface of polyurethane material fiber chemical fiber is bright, and the internal molecular structure is tightly deposited. Polyester hot melt yarn has good wear resistance.
Polyurethane material thermal fuse has the best wear resistance. Its properties are better than other chemical fibers and man-made fibers.
Polyurethane material thermal fuse has excellent light resistance properties. Lightfastness is second only to nylon.
Corrosion resistance of polyurethane thermal fuses against bleaching liquids, reducing agents, nitrogen compounds, ketones, petroleum products, and strong oxidants. It is resistant to dilute alkali and is not afraid of mold, but hot alkali will dissolve it. PU hot melt wire is weak in coloring, but has high color fastness to washing and is not easy to fade.
