Problems solved by technology

When most manufacturers in this field produce recycled PP spinning, their production mode is mainly to plasticize and granulate various waste materials, and then further melt-spin the plasticized granules. This production mode not only has a process flow It is complicated and cumbersome, and the obtained recycled polypropylene fiber does not have high stringiness, which is not conducive to its application and production
On the other hand, the traditional PP waste plastic recycling production enterprises, in the production and processing of recycling and regeneration, directly mix and plasticize PP waste plastics, melt them, then cool and cut them into PP plastic pellets, and then put them into PP plastic pellets. The plastic granules are re-melted and spun to make polypropylene spinning yarns. The traditional process not only cannot classify and use various waste PP, but also cannot classify and utilize various waste plastic products well, and cannot further improve the recycling rate. The quality of PP products

Abstract

The invention discloses regenerated polypropylene fiber yarns with degradability resistance and a production and preparation process thereof. The regenerated polypropylene fiber yarns comprise the following ingredients: a waste PP rope-like plastic, a waste PP plastic granular material, a waste PP jumbo bag material, a waste yarn material, a die head material, a water sinking material and coolingmasterbatch granules and masterbatch granules. A production enterprise can utilize and recover waste PP plastics of different types fully, can control the flowing rate of a liquid of the waste plastics fused by a screw by selectively choosing and proportioning the plastics, and ensures that the waste plastics fused can flow steadily in a box body. The spinning stability is ensured by means of stable material fusing index, and the regenerated polypropylene fiber yarns which are high in performance and quality are produced.

Description

technical field [0001] The invention relates to the technical field of recycling waste plastics, and more specifically relates to a degradation-resistant regenerated polypropylene yarn and a production and preparation process thereof. Background technique [0002] Plastic is a kind of artificial polymer synthetic polymer, which is a relatively new type of industrial material, and PP plastic (polypropylene) is another excellent resin variety developed after nylon. It is a high-density, no side chain, high Crystalline linear polymer with excellent overall properties. Plastics have brought convenience and benefits to people's life and production, but also produced a lot of pollution. According to statistics, about 70%-80% of the total plastics will be converted into waste plastics within 10 years, of which 50% It will be converted into waste plastics within 2 years. If these waste plastics are discarded at random or improperly disposed of, they will bring great pollution and h...
