Polyester masterbatch: The key additive for polyester coloring!


Polyester masterbatch is a functional additive specifically designed for coloring polyester fibers and products. By evenly dispersing pigments in the carrier resin, it provides stable and diverse colors for polyester materials and is widely used in the polyester processing field.


In terms of composition, Polyester masterbatch mainly consists of three core components: pigments, carrier resins and dispersants. Pigments are the core determinants of color and need to have good heat resistance and lightfastness to adapt to the high-temperature environment in polyester processing and the lighting conditions during subsequent use. The carrier resin usually selects polyester materials with good compatibility with polyester to ensure that the color masterbatch can be uniformly dispersed in the polyester melt and avoid uneven coloring caused by poor compatibility. The function of the dispersant is to reduce the cohesion between pigment particles, ensuring that the pigments are evenly distributed in the carrier in the form of tiny particles and guaranteeing the dispersion performance of the color masterbatch.


The production process of polyester masterbatch involves multiple procedures. First, mix the pigment, carrier resin and dispersant in proportion and achieve initial dispersion through high-speed stirring. Subsequently, the mixture enters the melt mixing equipment. Under the action of high temperature and shear force, the pigments are further refined and uniformly dispersed into the carrier resin, forming a molten mixture. Finally, after cooling, granulation and other processes, granular color masterbatch products are made. The entire process has strict control requirements for temperature and shear force to ensure that the pigment is fully dispersed and the particle size is uniform.


Stable performance is an important feature of polyester masterbatch. It has a high tinting strength. A small amount of addition can make polyester materials achieve uniform and rich colors, reducing the amount of pigment used. Meanwhile, the color masterbatch has good color stability, with small color differences between batches, which can ensure the consistency of product colors in large-scale production. In addition, high-quality polyester masterbatches have a relatively small impact on the original properties of polyester and will not significantly reduce the mechanical properties such as strength and toughness of polyester, ensuring that the colored polyester material can still meet the usage requirements.


Compatibility is a key characteristic of polyester masterbatch. As polyester processing is mostly carried out at high temperatures, the color masterbatch must have good heat resistance, not decompose or fade at the melt spinning temperature of 260-300℃, and avoid generating harmful gases or affecting the coloring effect. Meanwhile, the melt index of the color masterbatch needs to match that of the polyester melt to ensure uniform mixing with polyester during processing and achieve stable coloring.


In terms of application methods, polyester masterbatches are usually added to polyester raw materials through melt blending. Before polyester spinning or product molding, the color masterbatch is mixed with polyester chips in a certain proportion. After being melted through an extruder, the pigment is dispersed into the polyester melt along with the color masterbatch. Through the spinning or molding process, colored polyester fibers or products are made. This coloring method is easy to operate, has high coloring efficiency and can adapt to continuous large-scale production.


When using Polyester masterbatch, it is necessary to pay attention to controlling the addition ratio. If the addition amount is too small, it may result in insufficient coloring and a light color. If the addition amount is too large, it will increase the cost and may also affect the processing performance of polyester and the mechanical properties of the final product. In addition, the storage of color masterbatches should be protected from moisture to prevent the particles from clumping due to moisture, which may affect the dispersion effect. When matching with different types of polyester materials, the corresponding masterbatch model should be selected based on the specific variety and processing technology of polyester to ensure the coloring effect and product performance.


With the expansion of the application fields of polyester products, the performance requirements for polyester masterbatches are also constantly increasing. For different scenarios, polyester color masterbatches with special functions have been developed, such as functional color masterbatches with antibacterial and UV resistance properties, which not only endow polyester with color but also enhance its additional performance. These improvements have enabled polyester masterbatches to continue to play a significant role in the development of the polyester industry.
