Production process and application prospects of polypropylene fiber multicolor masterbatch

Multicolor polypropylene fiber masterbatch is a granular material formed by mixing highly concentrated pigments or dyes with polymer carriers. Its main function is to provide evenly distributed colors for polypropylene fibers or yarns during the production process. By adjusting the pigment concentration in the masterbatch, the color requirements of different shades and brightness can be met.

This masterbatch is mainly used in:
Non-woven fabric production
Medical protective materials
Industrial packaging bags
Household decorations (such as carpets, curtains, etc.)
Production process

The production of multicolor polypropylene fiber masterbatch usually requires the following steps:

Raw material selection

Polypropylene carrier: Usually a polypropylene resin that matches the final fiber material is selected to ensure excellent compatibility.

Pigment or dye: Inorganic or organic pigments are selected according to demand, emphasizing color fastness, light resistance and environmental protection performance.

Additives: Such as dispersants, antioxidants, etc., are used to improve the dispersibility and processing performance of the masterbatch.

Mixing and melting
The pigment, carrier resin and additives are fully mixed under high temperature melting conditions, and high shear force is used to ensure uniform distribution of pigment particles.

Granulation
The molten mixture is granulated by an extruder to form small particles with uniform diameter.

Quality Control
Color detection, temperature resistance test and fluidity test are carried out to ensure that the masterbatch meets the requirements of fiber production.

Product Advantages
Strong color stability
The masterbatch is evenly dispersed in polypropylene fiber, making the final product color consistent without color spots or color differences.

Excellent environmental performance
Multi-color masterbatch uses non-toxic pigments to reduce the pollution of water resources by liquid dyes during the production process, which meets the requirements of sustainable development.

Improve production efficiency
Traditional dyeing methods require multiple steps, while the use of masterbatch can simplify the process flow, directly color, and greatly improve production efficiency.

Strong adaptability
Applicable to a variety of processes such as spinning, non-woven fabrics and injection molding to meet the color needs of different fields.

Application areas
Non-woven fabrics
Multi-color masterbatch is widely used in non-woven fabrics used in sanitary products (such as diapers, masks), agricultural covering materials, and medical protective products to ensure the uniformity and durability of their colors.

Industrial fibers
Industrial ropes, fishing nets, carpet yarns, etc. require UV-resistant and wear-resistant color masterbatches to improve product performance and service life.

Household textiles
Household products such as curtains, cushions, and decorative fabrics have high requirements for color aesthetics and environmental performance, and multi-color masterbatches have become the preferred material.
