The development prospect of polypropylene masterbatch is wide. With the national industrial policy adjustment and energy conservation and emission reduction policies to continuously strengthen the policy, masterbatch coloring is gradually taking the traditional dyeing process market share. To account for more than 80% of China's chemical fiber production of polyester, for example, the current polyester industry demand for masterbatch is about 250,000 tons, and still 30% annual growth rate. However, China's total production of polyester fiber masterbatch in 2007 was only about 30,000 tons, and mostly middle and low conventional products. Fine denier, ultra-fine denier fiber masterbatch and functional masterbatch market demand urgency.

Masterbatch is made from a high proportion of pigments or additives with a thermoplastic resin, which is well dispersed and has a good wetting and dispersing effect on the colorant and has good compatibility with the coloring material The

Namely: pigment + carrier + additive = masterbatch.

In the "low-carbon economy", energy-saving emission reduction caused by the world's great attention to the moment, the chemical fiber textile industry is looking for a more clean way to solve the long-term environmental aspects of dyeing problems. At present, there are two ways of fiber coloring: post-spinning coloring and spinning before coloring. The use of masterbatch method for spinning before coloring, is recognized as environmentally friendly coloring method.
