Description
Technical Field
The invention relates to the technical field of high-strength fibers, in particular to a production process of a polyester blended polypropylene dyeable high-strength fiber.
Background
Polypropylene (PP) fiber is widely applied to the fields of daily life, building materials, traffic materials and the like due to the advantages of low density, low cost, good processability and the like. However, polypropylene fibers have poor dyeing properties, which limits their use in high-end textiles and color articles. At present, the most common and most productive method for coloring polypropylene fibers is the batch coloring technique, i.e., adding color master batch to the polymer prior to processing. However, this technique has a number of disadvantages including lack of high chroma colors, inability to correct by red dyeing, susceptibility to color streaks, and frequent breakage during finishing.
In order to improve the dyeing properties of polypropylene fibers, researchers have made extensive research in recent years, including chemical modification and physical modification methods. For example, by surface chemistry and functionalization, copolymerization and graft polymerization, plasma and gamma irradiation treatments, and blending polypropylene with additives such as polar polymers, metal compounds, inorganic nanoparticles (e.g., nanoclays), dendrimers, and hyperbranched polymers. However, these methods tend to be costly, complex in process, or environmentally unfriendly, and difficult to implement for industrial applications.
Among the numerous modification methods, melt blending of different kinds of polymer additives (such as polystyrene, polyamide and polyester) has proven to be an economical, viable and environmentally friendly modification process for PP fiber dyeability. Among them, polyethylene terephthalate (PET) has been attracting attention for its excellent dyeing property and mechanical property enhancing effect. In addition, recycling of waste PET has become a research hotspot with the increasing awareness of environmental protection. PET itself does not pose a direct environmental hazard, but is considered a toxic substance due to its high volume fraction in the waste stream and its high resistance to the atmosphere and biological agents. Therefore, by recycling waste PET (such as collecting, crushing and granulating) and using the waste PET for PP fiber modification, the dyeing property of the fiber can be improved, and the recycling of waste materials can be realized.
However, PET and PP are significantly different in polarity and chemical properties, and are incompatible, and direct blending can result in poor interfacial adhesion, affecting the mechanical properties and dyeing uniformity of the fibers. For this purpose, it is necessary to add a suitable compatibilizer, such as a thermoplastic maleic anhydride graft copolymer, to improve adhesion between the two phases, stabilize the blend morphology, and improve extrusion processability.

(Datacolor 600) the K/S value (ratio of dye absorption coefficient to scattering coefficient) was measured, the higher the K/S value, the better the dyeing property.
Color fastness testing:
Wash fastness the dyeable high strength fibres of the polyester blend polypropylene obtained in examples 1-4 and comparative examples 1-2 were treated in boiling water for 30 minutes and the colour change rating was assessed according to AATCC standards (a higher rating means better colour fastness).
Light fastness the polyester-blended polypropylene dyeable high-strength fibers obtained in examples 1-4 and comparative examples 1-2 were irradiated with a light fastness meter, and the gray scale was evaluated in accordance with ISO 105-B02:2014 (1-5 scale, higher scale means better light fastness).
Mechanical property test:
The polyester-blended polypropylene obtained in examples 1 to 4 and comparative examples 1 to 2 was measured for the breaking strength (cN/dtex) and elongation at break (%) of dyeable high-strength fiber using a universal material tester, and the CV value (coefficient of variation) was calculated. The data obtained are given in tables 1-3 below:
TABLE 1 dyeing property test results
