At present, most chemical fibers (chemical fiber filaments) are inseparable from chemical fiber masterbatches in the production process. These masterbatches have a great effect on their small size. The chemical fiber filaments woven by them are more environmentally friendly and have more diverse functions. The trend of the times.

At a time when the "low-carbon economy" and energy conservation and emission reduction have attracted great attention from home and abroad, the chemical fiber textile industry is looking for a single cleaner dyeing method to solve the long-term environmental protection problem in the dyeing process. At present, there are two ways of fiber coloring: post-spinning coloring and pre-spinning coloring. The use of masterbatch method for pre-spinning coloring is a recognized environmentally friendly coloring method.

The positive color masterbatch is a mixture of polyester or nylon 6 and pigments (or dyes melted in polyester or nylon melt). The content of the dye in the carrier is as high as 30%-40%wt. The production of masterbatch is to use a special screw to mix molten polyester or nylon with pigments or dyes in a predetermined ratio and sell them in the form of chips. The principle of pigment selection is: good compatibility with polyester or nylon 6, high temperature resistance of about 300 ℃, good dispersion in the carrier, and other firmness for the final use of the fiber (such as light resistance, washing resistance, abrasion resistance) ).

The development prospect of chemical fiber masterbatch is broad. With the adjustment of industrial policies in various regions and the continuous strengthening of policy support for energy-saving and emission-reduction enterprises, masterbatch coloring is gradually occupying the market share of traditional dyeing processes. Take polyester, which accounts for more than 80% of China's chemical fiber output, as an example. The current demand for color masterbatches in the polyester industry is about 250,000 tons, and it is still growing at an annual rate of 30%. However, the total output of my country's polyester fiber masterbatch was only about 30,000 tons in 2007, and most of them were middle and low-end conventional products. The market demand for fine denier, superfine fiber masterbatch and functional masterbatch is urgent.

The specific content is the above, but the overall summary is a single sentence. The masterbatch fiber is colored by the masterbatch method before spinning, which is a fiber product produced by a recognized environmentally friendly coloring method.

Chemical fiber masterbatches are also developing in the direction of multi-function and diversification, responding to the slogans of "sustainable development" and "green economy", let us witness the future of chemical fiber masterbatches to make more contributions to the industry.
