Brief introduction of wax printing fabric
Wax printing is wax resist printing and ancient Chinese name is Valerian.
It’s a historic printing and dyeing technology and still very popular in a few part of the minority areas in China Yunnan and Guizhou province.
The wax printing process is laying white cotton fabric to particular plate and using special wax knife to dip the melted wax to outline the pattern.
Put the fabric into vat for exhaust dyeing for several times and no-wax part will color up then boil off the fabric to remove the waxed part and then after drying, the white outline pattern will show on the blue ground.
These generate special styles with fine and irregular pattern due to wax film rupture by external force. This hand-made wax printing could only dye single white pattern on blue or red ground.
Mechanical printing was diffused to China since 1996 and the color shade has changed from hand-made single color to mechanical multi-colors.
Different patterns and techniques could design various wax patterns, it leaves 0.5-1cm width margins on the fabric edge and two sides have no color difference.
Moreover, the pattern stay simple and unsophisticated, flat coating block surface treatment and brilliant color matching.
Printing has changed from slow to fast, the technology process is also getting longer, using rotarty wax printing on two sides and dye different ground colors by insolubility Azo dyestuffs.
After mechanical drop-wax and wash off the floating wax on the fabric then use insolubility Azo dyes again to dye irregular simple and unsophisticated color. When completely desizing the wax on the fabric, it will use reactive dyes to make second time tracking printing, and finished the wax printing process.
