Products Description
PET whitening masterbatch is made by uniformly dispersing fluorescent whitening agents into PET chips. These whitening masterbatches can then be evenly spread throughout PET fibers without reacting or breaking said fibers. This process yields excellent color fastness and the ability to absorb invisible UV rays from the sun and reflect them as visible light in the 420-440nm range. This, in turn, provides a blue hue that enhances the overall whiteness of the fibers.

PET filament whitening masterbatch
PET filament whitening masterbatch is primarily used in the production of filament fibers. These fibers can be used in a variety of applications like clothing, shoes, and especially in the production of shirts, shoes, socks, medical garments, sports clothes, trademarks, sewing thread, white gloves, and more.
Recycled PET whitening masterbatch
Recycled PET whitening masterbatch is mainly used in the production of recycled bottles, as this masterbatch provides the necessary whitening effect that makes the fibers appear brighter and more vibrant. The fibers produced can be used in a variety of applications like pillows, cushions, sofas, dolls, space blankets, and more.

By using PET whitening masterbatch, clothing and other textiles can be made to appear brighter and whiter, while maintaining strength and flexibility. This process is widely used in a variety of industries and is an essential component of creating high-quality textiles. In addition, the use of PET whitening masterbatch in recycled materials helps to promote the use of sustainable materials and ultimately benefits the environment.
