Color masterbatch is an indispensable part of non-woven fabric raw materials. A good color masterbatch can ensure a more uniform and long-lasting color of the product. (Reference: How much does color masterbatch affect the quality of non-woven fabrics?) However, after purchasing color masterbatches countless times, do you really choose high-quality color masterbatches? The matching of the melt index of color masterbatch is very important, especially for melt blown color masterbatch. It is important to understand whether the melt index of color masterbatch suppliers meets the requirements of non-woven fabric production
When checking the quality of color masterbatches, you cannot ignore the following points:
- 1. The dryness and high moisture content of the color masterbatch can lead to poor spinning quality;
- 2. The quantity provided by color masterbatch enterprises is generally based on weight ratio content, rather than volume. Therefore, when selecting color masterbatches, accurate calibration is required for measurement comparison;
- 3. Many non-woven fabric enterprises rely on experience when purchasing, but in reality, different process conditions, raw materials, fiber sizes, non-woven fabric weights, roller temperatures, pressures, and rolling point shapes can all have an impact on color. Therefore, procurement personnel need to fully evaluate the company’s production process before purchasing and strictly follow the production process quality management procedures to determine, Ensure the perfect color of the finished product;
- 4. Choosing stable and reliable suppliers is particularly important. Because the production processes of different color masterbatch suppliers are different, it is easy to have a certain impact on the production stability and quality stability of non-woven fabric enterprises.
