Spunbond nonwovens are the fastest-growing varieties in the nonwovens industry and account for about 40% of total nonwovens production. Spunbond nonwovens based on polypropylene are widely used in medical materials, sanitary materials, furniture fabrics, carpet base fabrics, decorative materials, protective materials, and automotive industries.

Polypropylene is a pure linear saturated hydrocarbon polymer. It does not contain polar groups and active groups on macromolecules and has a high degree of chemical stability. Polypropylene fiber has high crystallinity, compact structure, and strong hydrophobicity. These characteristics make it difficult for polypropylene to provide dyed seats, and dye molecules cannot or hardly diffuse into their interior. Therefore, in order to improve the practicality and aesthetics of polypropylene nonwoven fabrics, pre-spinning dyeing of masterbatch is used in production. This paper analyzes the influence of the selection of non-woven masterbatch on the production of spunbond nonwovens.

The color masterbatch of the non-woven masterbatch refers to the color particles obtained by dispersing the pigment in a proportion of 20% to 80% by grinding or a twin-screw extruder evenly dispersed in the resin, and has excellent coloring effect and convenience. Automatic metering and transportation, energy conservation, no dust, no pollution and other advantages. The international masterbatch market is concentrated in the United States, Western Europe and Japan. China's masterbatch manufacturers are mainly distributed in Guangdong, Zhejiang, Jiangsu, Shandong, Beijing, and Shanghai. In the production of spun-bonded polypropylene, the selection of the components of the non-woven masterbatch is mainly considered from the following aspects.
