Reason of chromatic aberration in artificial turf production
There are many links that affect the quality of artificial turf, and many problems are caused. Among them, chromatic aberration is a common quality problem of artificial turf, and there are many ways to express chromatic aberration. The main reason for the color difference is that the raw materials of grass silk are not up to standard, the production line equipment technology is not up to standard, or the technology is not up to standard in the production process. First, the color difference is not completely caused by the overfeed. When replacing the new material, the remaining material in the screw could not be cleaned up, and the two phases were mixed, so that the ingredient composition of this part deviated from the set configuration, and the color of the straw drawn by the mixed part and the new material would be different. Second, the straight silk has multiple color differences. It means that there is a color difference between several strands of straight silk. Generally, it may be caused by problems in the setting of the spinneret opening, tension, and traction roller during the drawing of the straw. Third, the sharpness of the tip of the grass wire produces visual chromatic aberration. Grass bending is generally caused by inconsistent shrinkage of straight grass. The shrinkage of grass can be achieved by adjusting the drawing oven temperature, the setting oven temperature, and the annealing ratio.Fourth, the unevenness of the curved wire produces chromatic aberration. Uneven curvature of the silk will cause uneven and uneven surface of the artificial turf, which will cause visual chromatic aberration. The curvature of the curly grass must be uniform, which requires that the drawing process and formula are reasonable, and the temperature and air pressure of the curly machine are stable. Fifth, color difference caused by improper twist direction and twist. One twist of the twisted grass yarn is one twist. The number of twists per unit length is called twist, and the twist direction refers to the inclined direction of the grass fiber after twisting. The twist direction of artificial turf has a great influence on the appearance of artificial turf. Sixth, the rug is folds, and the rug folds produce chromatic aberration. Wrinkles are generally caused by the failure of the humidity to reach the standard when the base cloth is glued and dried. The folds of the blanket also cause the folds of the carpet surface. In addition, the improper winding of the grass may cause the carpet surface folds. Seventh, artificial turf products produced from different batches of raw materials may produce color differences when paved on the same site. The raw materials of different batches are often not completely the same, and generally have different degrees of difference, which will cause differences in the color of grass.
