pebble mills, attritors, sand mills, bead and shot mills, high-speed stone and colloid mills, high-speed dispersers, high-speed impingement mills, and horizontal media mills. However, it should be noted that roller and ball mills are somewhat outdated methods in current pigment base manufacturing technology.
grinding. If paste is used, reapply it to the polishing cloth every few min-utes. All types of diamond abrasives break down quickly and should be re-plenished frequently. Follow each polishing step with a thorough clean-ing, as in Subroutine 4.1. Use napless cloth for diamond pastes or suspensions and napped cloth
Pigment 1. It can be described as a localized form of dyeing, applying colorant to selected areas of the fabric to build up the design. Textile , like textile dyeing, is a process for applying color to a substrate. However, instead of coloring the whole substrate (cloth, carpet or yarn) as in dyeing, print color is applied only to defined areas to obtain the …
