Causes of Color aberration in production of artificial turf


  There are many links that affect the quality of artificial turf, and many problems are caused, among which color difference is a common problem of artificial turf quality, and color difference also has a variety of ways.

  The main reason of color difference is that the raw material of straw silk is not up to standard, or the equipment of production line is not up to standard, or the technology is not up to standard in the process of production.

  1. Overloading does not completely produce color aberration.

  When the new material is replaced, the residual material in the screw can not be cleaned up, and the two phases are mixed, which makes the ingredient composition of this part deviate from the set configuration, and the color of the grass silk drawn by the mixture part will be different from that of the new material.

  2. Straight silk with multiple chromatic aberrations.

  It refers to the color difference between several strands of straight wire, which is generally caused by the problems in the setting of spinneret opening, tension, traction roller and so on in the drawing process of straw wire.

  3. Visual color aberration is produced by the bending of the tip of the grass silk.

  The curving of the grass is usually caused by the inconsistency of the contraction rate of the straight grass.

  The shrinkage of straw silk can be achieved by adjusting the temperature of draft oven, setting oven temperature and annealing ratio.

  4. Uneven color aberration of curly wire.

  The uneven curvature of grass silk will result in uneven and uneven surface of artificial turf, resulting in visual color difference.

  The curvature of the curly grass must be uniform, which requires a reasonable drawing process and formula, and the temperature and pressure of the winding machine are stable.

  5. Color aberration caused by improper twist and twist.

  Twist twist A turn of twist in which the number of twists in a unit length is called twist, and twist direction refers to the inclined direction in which the fiber is twisted.

  The twist direction of artificial grass silk has great influence on the appearance of artificial turf.

  6. Blanket fold and blanket surface fold produce color aberration.

  The production of the fold is generally due to the drying of the floor cloth when the humidity is not up to standard, blanket fold caused by the blanket fold, in addition to the improper extrusion of straw silk will also cause blanket fold.

  7. artificial turf products produced by different batches of raw materials may produce chromatic aberrations when paved on the same site.

  Different batches of raw materials are often not exactly the same, generally there will be different degrees of difference, which will cause the difference in the color of grass silk.
