The matting agent used was nanoscale titanium dioxide.
Because the addition of the flatting agent has certain influence on the repeated stretching recovery performance of the spandex filament after multiple fixed elongations, the conventional spandex is prepared by taking polyurethane as a raw material and is polyester polyurethane, and in order to reduce the influence of the added flatting agent on the performance of the spandex, polyether polyurethane with the same dosage as the flatting agent is added into the leather part, namely, the leather part contains 2 wt% of the flatting agent and polyether polyurethane with the same content, and the balance is the polyester polyurethane. And the core is polyester polyurethane. In this embodiment, the skin portion and the core portion are concentric circles, and the area ratio of the skin portion to the core portion is 2: 5.
repeated tensile property tests were performed on spandex filaments without polyether urethane added to the sheath portion and spandex filaments with polyether urethane added to the sheath portion. The test is carried out according to the standard FZ/T5007-1994 spandex filament elasticity test method. The spandex filaments were tested at different constant elongations (300%, 400% and 500%) and at 20, 30 and 40 draw times, respectively.
The test results for spandex filaments without polyether urethane added to the sheath portion were as follows:
the test results for spandex filaments with polyether urethane added to the sheath portion were as follows:
