The advantages of TR fabric are as follows: (1) High strength, short fiber strength is 2.6~5.7Cn/dtex, high strength fiber is 5.6~8.0Cn/dtex.Because of the low moisture absorption, its wet strength and dry strength are basically the same, impact strength is 4 times higher than nylon, 20 times higher than viscose fiber. (2) good elasticity, elasticity close to wool, when elongation 5%~6%, can almost be completely restored, wrinkle resistance more than other fibers, that is, the fabric does not wrinkle, good dimensional stability, elastic modulus of 22~141cN/ Dtex, 2~3 times higher than nylon. (3) Good water absorption. (4) Good wear resistance, wear resistance is second only to the best wear resistance nylon, better than other natural fibers and synthetic fibers. (5) good light resistance, light resistance is second only to acrylic fiber. (6) Corrosion resistance, resistance to bleach, oxidant, jing, ketone, petroleum products and inorganic acid, resistance to dilute alkali is not afraid of mildew, but hot alkali can make its decomposition.
