GALLNUT

Methods of obtaining
Gallnut is harvested for dyeing and tannin. It is known that from the Sumerians to the present, gallnut shellacs have been used in various fields such as paint and leather making, and ink making. The collected gallnut is ground and boiled with wool. The resulting color is a color between dirty yellow and brown. A black color was obtained by mordanting the wool dyed in Tetre color with iron alum or mud containing iron.
Production Process
A strict quality control process is followed for the production of high quality powder and pigment products. The process begins with quality control testing of raw materials to ensure only the best materials are used. Next, the raw materials are ground to a fine consistency before being extracted in water. The extract undergoes evaporation and drying before undergoing another round of grinding. Batch mixing is then carried out to ensure a uniform blend of materials. Quality control testing is performed again to ensure the final product meets global standards. The product is then packed and supplied to the customers. We are proud to offer products available in both powder and pigment form as a range of options to choose from.
Dyeing Process
Natural fibres don’t have enough affinity to natural dyes. Therefore, a pre-treatment called “mordanting” should be done to increase the affinity of the fibres. It is also known as cationization. This process is the most crucial part because even dyeing mostly depends on even cationization of the fabric.
After mordanting and rinsing the fabric, the next stage is dyeing bath. During dyeing, dosage sequence and time should be followed carefully to have evenly dyed fabric.
The soaping step is then performed to remove any residual dyes off the fabric, improving both dry and wet rubbing fastness. It is an important step to be able to have good fastness results. The soap is also special and dedicated for natural dyes.
By following this meticulous dyeing process, we create high quality and sustainable textiles that meet the needs of our customers.
