specific Embodiment
[0008] The following is a specific embodiment of the present invention: a kind of easy dyeing apple flavor polypropylene staple fiber
[0009] The production process is as follows: polypropylene slice intrinsic viscosity IV=0.64dl / g, add 20% heterogeneous high polymer and 1% apple-flavored nano-microgel glue to the slice at the mixing bin at a ratio of 2%, after The pulse conveying method is sent to the wet slicing silo, and after drying, it enters the screw extruder. The temperature of the extruder is set at 270-285°C, the melt pressure is >10MPa, and the melt temperature is 290°C. It is measured by a frequency conversion metering pump. After the pump, the melt pressure is 15MPa. After being mixed by a high-efficiency static mixer, it enters the spinning box for spinning. The melt passes through a circular spinneret. Fiber, then through bunching, drafting, crimping, relaxation heat setting, cutting, packing, produce the polypropylene staple fiber described in this embodiment....
