B. by dried PBT, Masterbatch Homogeneous phase mixing, form tape after mixing by dual-screw pelletizer, cooling forming pelletizing form look mother section;
C. PET and look mother section are carried out drying and remove moisture, dried moisture controls at below 80PPm, and baking temperature is 130-140 DEG C, the molecular weight of PET is 30000 ~ 45000, viscosity is 0.8 ~ 0.9dL/g, and fusing point is 245 ~ 255 DEG C, and the mass ratio of PBT and PET is 20 ~ 40:60 ~ 80;
D. dried PET, look mother section are passed through screw extruder in proportion with plasticizer, carry out melt extruded, melt temperature is 250 ~ 255 DEG C, forms spinning molten liquid;
E. by spinning molten liquid with 60-120kg/cm
2pressure enter feed conduit in spinning manifold by screw rod head through bend pipe, to be extruded by filament spinning component after measuring pump supercharging, then through spinning shaft by lateral blowing slow cooling;
F. after slow cooling through oiling, reeling formation as-spun fibre;
G. as-spun fibre is carried out preheating with together with stretch, draw ratio is 2.5 ~ 3.5 times;
H. by the fiber after stretching through 150 ~ 190 DEG C nervous HEAT SETTING, obtain the blended apery of described PBT/PET after cooling processing and send out fiber.
Further, said method also has following prioritization scheme:
Extrusion pressure in steps d is preferably 80-110kg/cm
2.
Draw ratio in steps d is preferably 3 times.
Nervous heat setting temperature is preferably 160-180 DEG C.
The present invention is also claimed a kind ofly sends out fiber with the blended apery of PBT/PET that above-mentioned preparation method prepares.
PBT and PET to be undertaken blended by the present invention by specific preparation technology, the dependence of PBT fiber for temperature is not only reduced after blended, and it is soft to remain PBT fabric hand, hygroscopicity, ABRASION RESISTANCE and fiber crimp are good, and have the advantage of good dyeability.PBT fiber can be made to send out in fiber at apery be more widely used.
The blended apery of PBT/PET prepared through this technique sends out fibre diameter between 70-90 μm, the fiber number of fiber is 50-70dtex, fracture strength is at 2.2-2.5cN/dtex, elongation at break is 95%-100%, modulus is at 14-15cN/dtex, feel exactly likes natural human hair, may be used for hair product industry, substitute natural human hair, production cost is low, be convenient to suitability for industrialized production, the apery produced is sent out fiber and is had excellent chemical stability, heat endurance, intensity, rigidity, the fibrous physical properties such as ABRASION RESISTANCE, and there is the gloss of natural human hair and excellent elasticity, drapability, not fugitive color, easy moulding, easy arrangement, exactly like natural human hair, repeatedly can roll up with curler, carry out having one's hair waved shaping, all right stretching rewind, have a good application prospect and economic benefit.
