1. Bleaching and discoloring of grass fibers?
1. The quality of straw fiber is not up to standard, for example, the dosage of anti-ultraviolet (UV) agent and anti-aging (amine) agent is too small.
2, the formulation of grass fiber is not scientific, and some of the inferior quality additives are more.
3, the production equipment of artificial grass fiber is backward, the technology is poor, and the physical properties are unstable.
4, environmental impact, such as strong ultraviolet radiation in some areas, acid rain corrosion, industrial pollution and so on.
Two, grass fiber fuzzing, pilling and powdering?
1. Because of the high frequency of school use, the quality of reticular fiber is poor in 1-2 years, the better quality in 4-5 years will have varying degrees of grass fiber split into 50-60 filaments phenomenon;
2, PP fiber itself is relatively hard and brittle, easy to pilling and pilling.
Three, grass fiber shedding, hair loss?
1, poor production technology, poor quality of artificial grass cloth and glue, resulting in poor overall binding power to grass.
2, grass fiber uses low-end grass (such as PP material), and the grass thread is interrupted from using.
3, the auxiliary materials are not qualified (quartz sand particles are too large, not round), which cause damage to the grass.
