  10. The flow of aluminum oxide on fabric surface is done at 10-20° angles.
  11. The blowing angle is very important.
  12. Higher the blowing angle higher the fading affect & higher the risk of fabric damage.
  13. The operators should have protective standard musk, helmet, gloves, ear plug and uniform.
  14. Production/hour/gun varies from 25-50 pcs garments depend on the area, extent of fading.
