At Tat Fung, we care about the environment. Therefore, we always look for ways to improve our environmental performance, and to be a responsible enterprise. We strive to be at the very front of the textile industry, and it is our goal to not only improve our own standard, but to continuously set new benchmarks in environmental performance for the industry to follow.

To protect the environment, Tat Fung continues to develop a wide range of eco-products by using eco-materials through certified suppliers. We do this because it is important for us that our supply chain and partners are also committed to reducing their impact on the natural environment. In addition, we recycle water, and apply eco-washing technology to reduce the consumption of water and chemicals used for denim and piece-dye finishing. To further protect the environment, we also use advanced sewage treatment systems and an eco-processing route to recycle and reduce consumption. 

Tat Fung utilises the best quality cotton yarns available on the market. We are working hard to acquire more of our materials from sustainable sources such as BCI and Cotton LEADS™. At the same time, we are continuously introducing new and innovative eco-materials, such as REPREVE® (fibres made from recycled plastic), to produce denim and piece dye in a sustainable manner, without compromising the quality of our products. 

What is EQUA?

Developed by Panther Textiles Holding and Tat Fung Textile Co., Ltd., EQUA is a patented technology that combines initiatives in four different stages of the textile manufacturing process, to minimize the environmental footprint and help create a cleaner world.

The four stages involved in EQUA are raw material, spinning, dyeing and finishing. The combined results are more raw material sourced through The Better Cotton Initative (BCI), a very significant 80% reduction in water consumption, increased production efficiency, as well as enhanced product quality.

The First Stage

Raw Materials

Panther Textiles Holding and Tat Fung Textile Co., Ltd. are members of the Better Cotton Initiative (BCI). BCI is a non-profit organization that works to ensure fair trade and sustainable cotton worldwide.  BCI exists to make global cotton production better for the people who produce it, better for the environment it grows in, and better for the sector’s future, by developing Better Cotton as a sustainable mainstream commodity. As a result, we ensure that the production process start of right from the first stage - promoted by sustainable raw materials and fair trade.

The Second Stage

Spinning Process

EQUA is also integrated in the spinning process, where the cotton is turned into yarn. In this stage, we have changed from the conventional methods of spinning, such as ring-spun and open-end yarn, to low-twist yarn. By doing so, Panther Textiles can now spin the same yarn count with 11% higher production efficiency. This has also resulted in a 13% reduction in electricity consumption. In addition, the low-twist yarn also creates a softer hand feel to the fabric, increasing the comfortability of the finished products.

The Third Stage

Dyeing Process

Indigo dyeing is the traditional and most commonly used method for dyeing denim fabric. With the traditional method, 8-12 vats are required for the color to be sufficiently absorbed into the fabric. Now however, with EQUA, we have developed a new method that replaces the indigo dyeing with liquid sulphur. By doing so, we have reduced water consumption from 89,900 liters to 44,700 liters of water per 10,000 meters of fabric we produce. These savings amounts to the water needed to produce over 6,200 pairs of jeans. The 50% reduction in water consumption also increases the production efficiency as the liquid sulphur only require 2 vats, instead of the traditional 8-12 vats. The reason for this significant reduction is that the liquid sulphur much more efficiently binds color to the fabric.
The water still used for dyeing is moved to our water treatment facility after use, where it goes through a thorough water purification process before being safely discharged.

The Fourth Stage

Finishing Process

In order to further reduce water and energy consumption, Panther Textiles has invested in state-of-the-art equipment that utilises liquid ammonia for the finishing mercerisation process. Mercerisation adds a protective layer to the finished fabric that enhances both the quality, and the aesthetic properties of the fabric. Caustic mercerisation is usually used for this process, which requires large amounts of water to wash of the surface alkaline. By changing from caustic mercerisation to liquid ammonia, we now only use 1,400 litres of water per 10,000 meters of fabric, which is a 98% reduction of water consumption in the finishing process. 

After use, the residual ammonia is moved to our recycling module, where the ammonia is again liquefied by using low temperature and cooling water.

All stages combined

The power of equa

All stages combined, EQUA has resulted in a significant 80% reduction in our water consumption. For each pair of jeans produced, we can now save 28 liters of water. For every 10,000 meters of fabric we produce, this amounts to saving more than 173,000 liters of water. In one year, we can save over 949 million liters of water. Enough water to fill 380 Olympic sized swimming pools, or cover the water consumption of 20,000 people for a full year.

Panther Denim is continuously improving manufacturing processes and also developing new products and application processes that achieve sustainability target. EQUA is used to minimize water consumption and chemicals, eliminate waste, and reduce energy in all processes.
We now upgraded our EQUA to EQUA+, more blue, more green. EQUA+ offers more dyeing shades and able to be laser-washed to the textile market. This ultimate transformation towards a brighter blue industry will come soon from our EQUA+ project.
