PTT fiber is a kind of polyester fiber with excellent performance. It is a polyester fiber formed by polycondensation of 1,3-propanediol (PDO) and terephthalic acid (PTA).
(1) Because PTT fiber has one more carbon element than polyester fiber in structure, PTT fiber is easy to be dyed. It can be dyed continuously in boiling water without carrier and at low cost.
(2) PTT fiber has low melting point, low glass transition temperature and easy to crystallize, so it has good dyeing performance. The glass transition temperature of PTT fiber is 55 ℃, polyester fiber is 81 ℃, and the dyeing performance of PTT fiber is better than polyester fiber, with high dye uptake and dye penetration, so it has uniform color and good color fastness.
(3) The surface morphology of PTT fiber is basically similar to that of polyester fiber, and the internal macromolecular structure is spiral macromolecular multi carbon structure, which makes the fiber have good elasticity and recovery rate, and the tensile recovery is better than that of nylon and polyester fiber. When the external force is applied, the low modulus area of the product body will be deformed. When the external force is released, the crystal structure will be tightened, making it return to the original state. In the low elongation state, the rapid elastic recovery rate of PTT fiber is human.
(4) PTT fiber is bulky, soft and comfortable to wear. The fiber has poor water absorption, good dry performance, good washing and wearing performance, small Yang's mold and good drapability. The elasticity of PTT fiber can be compared with that of nylon, K is larger, the elasticity resilience of PTT fiber is higher than that of nylon, and the elastic recovery rate is larger. After being stretched, PTT fiber can still be completely restored to its original state.
