Embodiment Construction
[0017] In order to make polypropylene staple fibers multifunctional, the present invention uses modified diatomite and polypropylene to melt blend to prepare polypropylene masterbatch and polypropylene slices as raw materials, wherein the specific preparation method of polypropylene masterbatch is: first use aluminum Ester coupling agent modifier and industrial salt additive to modify diatomite, specifically 0.5% to 2.0% aluminate coupling agent, 0.5% to 1.0% industrial salt and 97% to 99% diatomite Feed into the high-speed mixer, mix in the high-speed mixer at 800 rpm to 1000 rpm for 20 minutes to 30 minutes, and then naturally cool to room temperature to obtain modified diatomite; then In terms of weight percentage, take 5%~20% modified diatomite, take 80%~95% polypropylene, feed them into the mixer for thorough mixing, and the evenly mixed mixture is transported to the feeding hopper of the granulator by airflow , and then the twin-screw under the feeding hopper heats, melt...

Abstract
The invention discloses a multifunctional polypropylene staple fiber and a production technology thereof, and belongs to the technical field of the preparation of novel industrial materials. Polypropylene master batches and polypropylene slices prepared by the melt blending and granulation on modified kieselguhr and polypropylene are taken as raw materials and are respectively added into a fusion screw A and a fusion screw B; after fibers are formed, the formed fibers pass through a spinning oil tank oil feeding roller, a three-channel draw machine, a first-channel setting machine and a crimping machine to obtain a fiber bundle; the above fiber bundle passes through a second-channel setting machine, a fiber shaping machine, a cut-off machine, a fiber finishing machine and a packaging machine to obtain the multifunctional polypropylene staple fiber. The strength and the elongation of the multifunctional polypropylene staple fiber prepared with the production technology are both improved, and the multifunctional polypropylene staple fiber also has the functions of absorbing formaldehyde and peculiar smell, deodorizing, sterilizing, disinfecting, releasing negative oxygen ions, resisting heat, retarding inflaming, resisting aging, absorbing light, carrying out extinction, purifying air, breathing, regulating humidity, absorbing sound, denoising and the like. When the polypropylene staple fiber is used as an automobile interior trimming material, the weight is lightened than that of an automobile interior trimming material with the same thickness, and social benefit and economic benefit are obvious.
Description
technical field [0001] The invention belongs to the technical field of preparation of new industrial materials, and in particular relates to a multifunctional polypropylene short fiber and a production process thereof. Background technique [0002] Now my country has become the largest automobile production and sales country in the world, and the production and sales volume of automobiles in 2016 has exceeded 25 million.
