A:(1) Low linear density: the linear density range of polyurethane elastic fiber is 22 ~ 4778dtex, the finest up to 11dtex; The finest rubber wire is about 180 (about 156dtex), more than ten times thicker than the former.
(2) High strength: the breaking strength of polyurethane elastic fiber is 0.35 ~ 0.88dN/tex in wet state and 0.5 ~ 0.9dN/tex in dry state, which is 2 ~ 4 times that of rubber wire.
(3) Good elasticity: the elongation rate of polyurethane elastic fiber is 500% ~ 800%, and the instantaneous elastic recovery rate is more than 90%, which is almost the same as rubber wire.
(4) Good heat resistance: the softening temperature of polyurethane elastic fiber is about 200 degree , melting point or decomposition temperature is about 270 degree , better than rubber wire, in the chemical fiber is a good heat resistance variety.
(5) Strong moisture absorption: rubber silk is almost no moisture absorption, and at 20 degree , 65% relative humidity, the moisture regain of polyurethane elastic fiber is 1.1%, although smaller than cotton, wool and nylon, but better than polyester and polypropylene.
(6) Low density: the density of polyurethane elastic fiber is 1.1 ~ 1.2g/cm3, although slightly higher than rubber wire, but in the chemical fiber is still a lighter fiber.
(7) Excellent dyeing: because polyurethane elastic fibers have sponge-like properties, all types of dyes can be used for dyeing. In the use of bare silk, its superiority is more obvious in addition, polyurethane elastic fiber also has good weather resistance, flexural resistance, wear resistance, resistance to general chemicals and so on. However, the stability of sodium hypochlorite bleach is poor, and sodium perborate, sodium persulfate and other oxygen-containing bleach are recommended. Moreover, the polyurethane elastic fiber of polyether type has good hydrolysis resistance; And polyester polyurethane elastic fiber alkali resistance, hydrolysis resistance slightly worse.
