How is polypropylene industrial silk colored in production?

How is polypropylene industrial silk colored in production? Let's take a look.

Polypropylene in the macromolecular structure does not contain chemical groups that can be combined with dyes, so dyeing is more difficult.

1. Using melt coloring method, the pigment preparation and polypropylene polymer are evenly mixed in the screw extrusion press, and the colored fiber is obtained with high color fastness after melt spinning.

2. Copolymerization or graft copolymerization with acrylic acid, acrylonitrile, vinylpyridine, etc., so that polar groups that can be combined with dyes are introduced on polymer macromolecules, and then directly dyed by conventional methods.

In the process of polypropylene production, various additives are often needed to improve dyeing, light resistance and fire resistance.

Polypropylene industrial silk made of polypropylene polypropylene wire, because of its low price, high strength, anti-aging, wear resistance, salt water corrosion resistance, good elasticity and other characteristics, mainly used in sewing cement bags, fertilizer bags, plastic woven bags, fishing net weaving and other industries.

Geotextiles woven with polypropylene industrial silk, suitable for roads, railways, airports, seawall, canals, reservoirs, ports and Bridges and other projects, with no need to break, build cofferdams, dam drainage and speed, high efficiency, investment province, good quality and other advantages, especially in the case of large load, woven geotextiles than non-woven geotextiles have many unique features. Using its acid and alkali resistance, corrosion resistance, high strength, no water absorption, light weight, good stability, good filter stripping and other advantages, can be made of high-strength polypropylene fiber filter cloth, mainly used in metallurgy, mineral processing, chemical industry, light industry, food, environmental protection and other industries.
