The invention relates to the
polyacrylonitrile and the producing process. The weight percent of the adjusting temperature is showed below: the
acrylonitrile 30.0-92.5%; the second
monomer 2.5-20.0%; the chain transferring
reagent 0.03-0.3%; the solicitation
reagent 0.05-0.4%; phase changing material tiny
capsule 5.0-50.0%. the producing process adopts the said adjusting
fiber material, the solicitation
reagent is used to bring the second
monomer and the existing possibly third
monomer and the water phase deposit of the chain transferring reagent to converge in the phase changing material tiny
capsule hanging
chaotic liquid, the
polymer produced form the action contains the said percentage of the phase changing material tiny
capsule, the mixing
hybrid of the
acrylonitrile sharing material and the phase changing material tiny capsule is gained; the gained equal
hybrid is cleaned by the secondary or thrice
ion water and dried under the temperature of 45-95 degree, the filature is melted under the temperature of 10-40 degree above the
melting point of the
acrylonitrile gathering material in the screw extruding engine to produce the said adjusting temperature
fiber. The said adjusting temperature
fiber has many merits such as the good function of absorbing or releasing the
heat energy, the high
machine intension and the low cost.
