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....

Abstract

The invention aims to provide easily colored polypropylene fiber which can also emanate a variety of aromatic odors. The invention adopts the technical proposal that the out-phase high polymeric compound with larger coloring seat space is mixed into the polypropylene fusant through microinjection method, simultaneously, the nanocapsules with a variety of flavors are added according to the requirement of the product, then the production is performed according to the production method of conventional sliced sheet spinning. The usage of the product of the invention is wide, which can be commonly used for the textile materials for clothes manufacturing and industry.

Description

technical field [0001] The invention relates to a polypropylene fiber, specifically a polypropylene fiber which is easy to dye and has the function of emitting fragrance, and belongs to the technical field of chemical fibers. Background technique [0002] Due to the special molecular structure of polypropylene fiber, it is not easy to dye, especially dark or bright colors. At the same time, general polypropylene products are odorless. In order to obtain aromatic polypropylene products, the existing method generally adopts the blend spinning method, which is to add various aromatic agents in the spinning process to produce, but because the properties of these additives decay quickly, the smell cannot be maintained for a long time . Contents of the invention [0003] The object of the present invention is to provide a kind of polypropylene fiber which is easy to dye and can emit various aromatic smells. [0004] The technical scheme adopted by the present invention is: mi...
