Wax thread production process is quite slow. First, semi-finished products are made from high quality polyester fiber mono-filament, then waxed by high temperature environmental protection waxing equipment, cooling, polishing and setting, finally a complete wax thread is formed. Cooling and polishing require some technical experience. General factories have omitted this process because of troubles. However, this process can best reflect the fine and quality of wax thread. Round wax thread specifications are:0.35 mm, 0.45 mm, 0.55 mm, 0.65 mm, 0.8 mm.
