Why Does Man-made Lawn Produce Chromatic Aberration?

Artificial turf is something that can be seen in many places, such as plastic playground, artificial courtyard and temporary activity scenes. It can create a natural and green atmosphere for the whole scene and also cover some poor environments. However, because it is the artificial turf that occasionally has color difference in perception, a smaller color difference will not affect anything, and a slightly larger color difference will affect the image, Therefore, the color difference of artificial turf still needs to be a part of quality control, so we have made a little analysis on the causes of color difference of artificial turf.
Analysis on the causes of color difference of artificial turf:
1. Improper raw material ratio before artificial turf production
In the process of producing plastic artificial turf, different kinds of artificial turf need to change raw materials. In this case, the remaining materials in the instrument may not be cleaned or used up. Therefore, a variety of production materials will be mixed together, resulting in an error between the proportioning composition and the previously set proportion. Let the final production of plastic artificial turf have color difference.
2. There is color difference between the multi-core straight strands of straw
In the production process of plastic artificial turf, the straw may be affected by the opening of the spinneret, and the tension, the setting of the traction roller and other related links may cause the color difference problem.
3. Different shrinkage of straw
The straw of plastic artificial turf will stretch at the oven temperature, and the temperature and annealing ratio of the shaping oven can adjust the shrinkage rate. If the straight grass shrinks inconsistently, the produced straw will have color difference.
4. Shredded grass
The grass silk of the plastic artificial lawn is improperly extruded during the production process, or the moisture of the adhesive on the bottom cloth does not meet the standards, which will cause wrinkles and visual color difference from the appearance.
5. Different raw materials for lawn production
The materials required for the production of plastic artificial turf are raw materials of different batches. The physical properties (color, hardness, elasticity, etc.) of each batch of materials may be different, and then the color of the plastic artificial turf grass may be different, which means the color difference exists.
