From Hank Dyeing to Fabric Dyeing: TECCO’s Transformation from Volume to Quality

In 1996, Yangjia Machinery was founded in Wuxi. Yangjia built a strong reputation in China’s hank dyeing market. Through more than 20 years of steady effort, the PDM Yangjia brand once held over 30% of the national market. Repeat orders kept coming, and its equipment could be found across the country.

But crisis often hides at the moment of greatest success.

From 2009 to 2010, orders began to slip. The problem was not the equipment—the machines were still good. The market downstream had changed. More and more fabric mills shifted from dyeing yarn first and then weaving to weaving first and then dyeing. The yarn-dyed fabric market was shrinking. Once an industry trend takes hold, it rarely reverses. The ceiling for hank dyeing machines was already visible.

Should we defend the No. 1 position and slowly contract, or jump into a completely unfamiliar field? In 2010, we chose the latter: develop fabric dyeing equipment from scratch.

Fabric dyeing and hank dyeing follow completely different technical logic. A hank dyeing machine processes yarn. Fabric dyeing equipment handles entire pieces of fabric. Tension control, crease prevention, liquor ratio optimization, and uniformity—each area was a new challenge.

At the time, airflow dyeing machines were known for low energy consumption, but they also had common problems: high power consumption, low air pressure, uneven airflow distribution across tubes, excessive fuzzing on short-staple fabrics, and poor color fastness. Our goal was clear: build a new machine that balanced quality and cost. Not simply copy what was already on the market, but solve real technical pain points in the industry.

In 2014, the breakthrough came. We introduced our first dual-outlet direct-drive fan.

The core value was simple: significantly higher air pressure, while greatly reducing fan energy consumption and noise. Traditional airflow dyeing machine fan designs struggled to achieve both air pressure and energy efficiency. The dual-outlet direct-drive design broke through that bottleneck.

This was not only our first major technical breakthrough in fabric dyeing equipment, but also one of the core competitive strengths of the later STORM series.

In 2015, Deyijia Machinery Jiangsu Co., Ltd. was officially established. Under the Deyijia brand, we focused on three eco-friendly fabric dyeing machines—Banana, Koala, and STORM—and one low-liquor-ratio garment dyeing machine.

From the start of the transformation in 2010 to the full rollout of products in 2016, Deyijia spent six years completing its strategic shift from a hank dyeing machine supplier to a fabric dyeing equipment manufacturer.

Looking back, Deyijia has always focused on three things:

Quality first. ISO 9000 certification and Class II pressure vessel manufacturing license. Every machine is built to withstand rigorous on-site testing before it leaves the factory.

R&D reputation: from a single product to a technology matrix. The success of the STORM series opened the door to the fabric dyeing market. But real transformation does not rely on one product. It requires a complete technology matrix. Deyijia went on to launch multiple dyeing machines for different fabrics and processes, covering woven, knit, synthetic, and home textile applications. This completed the upgrade from “equipment available” to “solutions available.”

After-sales service. Application engineers are stationed on-site to guide trial production, follow every batch from lab sample to bulk production, and make adjustments on the spot until consistency is achieved. A cross-functional application team that understands both machinery and dyeing has become a core advantage that sets Deyijia apart from other equipment manufacturers.

Final thoughts

The results of the transformation are ultimately reflected in market and customer recognition. From “winning by volume” in the hank dyeing era to “standing on quality” in the fabric dyeing era, Deyijia has completed a true corporate transformation.

Behind this is not a simple product-line switch, but continuous investment in R&D, a deeper understanding of customer needs, and a commitment from management to the technical team to build a technology-driven company.

Thirty years of accumulation give Deyijia the confidence to say: transformation is not about abandoning the past. It is about building on it—creating a path with higher technical value and greater customer value.
