1. Why do your non-woven fabric products tend to have color variations?

Many purchasing colleagues have reported that during the production process, the instability of colors between batches is a particularly troublesome issue. In fact, this is often related to the carrier and diffusion properties of the Polypropylene fiber masterbatch. 

We suggest that when making your selection, you should pay particular attention to the compatibility between the color masterbatch and your substrate. For high-quality Polypropylene fiber masterbatches, the carrier resin should have a high matching degree with your PP raw materials, so that it can be rapidly dispersed in the molten state and avoid the appearance of "fuzziness" or "crystalline points". In addition, changes in temperature and humidity in the production environment will also affect the hygroscopicity of the color masterbatch, which in turn will affect the final color tone. Therefore, we usually recommend that customers properly dry the color masterbatch before use, which can effectively reduce the color difference fluctuations caused by moisture. 

II. How to balance cost and product quality?

During the procurement process, price is often an important consideration, but it should not be the sole criterion. Some low-priced color masterbatches, in an effort to cut costs, incorporate excessive calcium carbonate or recycled materials. This can lead to frequent replacement of your equipment's filter screens and even affect the breaking strength of the non-woven fabric.

We recommend that when evaluating Polypropylene fiber masterbatches, you should make a "comprehensive calculation": check if the waste rate after use has decreased, if the equipment maintenance costs have reduced, and if the final product's feel is better. Although high-quality color masterbatches may have a slightly higher unit price, they can ensure uniform fiber fineness, no pits, and thereby improve your yield and market competitiveness. 

Selection suggestion:

When purchasing Polypropylene fiber masterbatch, avoid blindly pursuing low prices. We recommend that you first request samples for on-machine testing, and pay particular attention to its dispersion effect on your existing equipment and its impact on production pressure. The one that suits your production process and can stably produce high-quality non-woven fabric is the better choice.
