Soft-texture regenerated polypropylene yarn and production and preparation process thereof

A preparation process, polypropylene technology, applied in the direction of conjugated synthetic polymer rayon, adding pigments in spinning solution, etc., can solve the problem that the quality of recycled PP products cannot be further improved, and waste PP cannot be classified and used for production and recycled polypropylene. It does not have problems such as high wire drawing, and achieves the effect of unique performance and stable quality, reducing the use of adjustment accessories and reducing labor.

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

Embodiment 1

[0024] A regenerated polypropylene yarn with soft texture, the regenerated polypropylene yarn includes the following components: waste PP rope-shaped plastics, waste PP yarn materials, regenerated PP plastic granules, cooling masterbatches and color masterbatches, wherein , the mass parts of the ingredients of each component are respectively: 60 parts of waste PP rope plastic, 10 parts of waste PP yarn material, 23 parts of recycled PP plastic granules, 3 parts of cooling masterbatches, 4 parts of color masterbatches . The waste PP rope plastic is variegated horse grass thick rope material, and the regenerated PP plastic granulate is waste PP packing belt granulate.

[0025] The above material formula is produced to prepare recycled polypropylene yarn, and its process includes the following specific steps:

[0026] Step 1: Separately select waste PP rope plastic and waste PP yarn;

[0027] Step 2: Breaking or shearing the selected materials respectively, and rinsing with cle...

Embodiment 2

[0035] A regenerated polypropylene yarn with soft texture, the regenerated polypropylene yarn includes the following components: waste PP rope-shaped plastics, waste PP yarn materials, regenerated PP plastic granules, cooling masterbatches and color masterbatches, wherein , the mass parts of the ingredients of each component are respectively: 61 parts of waste PP rope plastic, 9 parts of waste PP yarn material, 24 parts of recycled PP plastic granules, 2 parts of cooling masterbatch, 4 parts of color masterbatch . The waste PP rope plastic is variegated horse grass thick rope material, and the regenerated PP plastic granulate is waste PP packing belt granulate.

[0036] The production process of the mixed ingredients of the above ratio is the same as that of Example 1, and will not be repeated here. The mixed ingredients of this Example 2 can also be produced as high-performance regenerated polypropylene yarn produced in Example 1.

Abstract

The invention discloses a soft-texture regenerated polypropylene yarn which contains the following materials: waste PP rope form plastics, waste PP yarn material, regenerated PP plastic particles, cooling master batch and color particle material. According to the invention, a production enterprise can sufficiently utilize and recycle various different kinds of waste PP plastics, and can well control the flow rate of liquid after the waste plastics is melted in a screw after selective selection and proportion, and therefore, steady flow of the waste plastics after melting in a box can be ensured, the stability of spinning yarn is ensured by utilizing steady material melting index, and the regenerated polypropylene yarn with high performance and high quality can be produced.

Description

technical field [0001] The invention relates to the technical field of recycling waste plastics, in particular to a soft 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 harm to the human environment. Peo...
