Abstract
The invention discloses a preparing method for a wave absorbing composite filament and a textile. The preparing method includes the steps that firstly, acrylonitrile, dimethyl sulfoxide, itaconic acid and azobisisobutyronitrile are mixed and polymerized for 21-24 hours at the temperature of 60-65 DEG C, and a PAN polymerization solution with the solid containing content of 20%-21% is obtained; secondly, nano-iron powder is added into the PAN polymerization solution, and a PAN compound solution is obtained after even stirring is conducted; thirdly, the composite filament is prepared through a wet spinning technology, wherein under the pressure of 3-3.5 MPa, the PAN compound solution conducts filament spraying through a spinneret plate, solidification is conducted in a coagulation bath, the filament is formed, and the composite filament which has the wave absorbing property is obtained through washing and drying. According to the preparing method for the wave absorbing composite filament and the textile, a spinning solution is modified through the nano-iron powder, and therefore the obtained composite filament and the obtained textile have good wave absorbing performance and are wide in wave absorbing frequency bandwidth and high in strength.
