Antai Textile Industry: Dope Dyeing Technology Aligns with Industry Trends, Reducing Carbon Emissions by 35% to Lead Textile Green Transformation

In Zhangjiagang in July 2025, the summer heat was intensifying, but there was a calm busyness in the production workshop of Antai Textile Industry – the dope-dyed acrylic fiber production line was operating stably at 95% capacity. Rolls of vibrant colored acrylic sliver were being sent out from the end of the assembly line, soon to be shipped to the eco-friendly fabric workshop of a leading apparel brand in Zhejiang. Li Xiong, the Marketing Manager, walked into the Production Department holding a freshly printed industry trends report. Factory Director Huang was staring at the real-time data on the central control screen. Their eyes met on the headline "Dope Dyeing Technology Reduces Carbon Emissions by 35%", and they exchanged a smile.

"Hebei Aikerui just authorized the preparation method for black dope-dyed fibers, and with the industry listing dope dyeing as a key focus this year, we've really aligned with this trend," Li Xiong shook the report in his hand, his指尖划过 the words "12 leading enterprises have completed pilot production line layouts". "Three years ago, when we decided to switch from traditional dyeing to dope dyeing, many customers were worried about color stability. Now it seems we chose the right technical path."

Factory Director Huang pulled up a set of data; the curves on the screen clearly showed that since Antai Textile Industry put its first dope-dyed acrylic sliver production line into operation in 2022, the product defect rate has dropped from 8% (with traditional dyeing) to 1.2%, and carbon emissions per ton of product have been reduced by approximately 280 kg compared to traditional processes, exactly matching the "35% carbon reduction" calculation in the industry report. "Do you remember that Japanese customer in 2023? They specifically requested undyed acrylic sliver for eco-friendly children's clothing. At that time, we had just succeeded in pilot testing and managed to control the color difference of the first 50-ton order to △E ≤ 1.5 despite the pressure. Now, 80% of their autumn-winter collection uses our colored acrylic fiber."

As a textile "veteran" founded in Zhangjiagang in 1993, Antai Textile Industry has stepped on the nodes of industry transformation at every step: from initial production of ordinary acrylic yarn, to focusing on colored acrylic sliver in 2010, and then betting on dope dyeing technology in recent years. Li Xiong recalled that in 2021, the Marketing Department conducted a survey and found that inquiries from downstream brand customers about "eco-friendly fabrics" increased by 47% year-on-year, with "waterless printing and dyeing" and "low-carbon fiber" being high-frequency terms. "At that time, Director Huang led the technical team to visit the Institute of Chemistry, Chinese Academy of Sciences three times, spending eight months tackling color masterbatch dispersion technology, and finally solved the common 'color spot' problem in dope dyeing."

Today, Antai Textile Industry's colored acrylic sliver covers 28 regular color numbers including red, blue, and gray, among which dark gray and navy blue have passed the international OEKO-TEX® Standard 100 certification, making it one of the few domestic enterprises capable of stably supplying dark-colored dope-dyed acrylic fiber. "Traditional dyeing requires multiple processes such as scouring, dyeing, and fixing, which consumes a lot of water and electricity," Director Huang pointed to the water circulation system outside the workshop. "Our dope dyeing adds color masterbatch directly during the spinning stage, eliminating the dyeing and finishing process entirely. This not only reduces costs by 15% but also shortens customers' fabric production cycle by nearly a week."

Just last week, Li Xiong signed a large order for 200 tons with a domestic sportswear giant, which requires dope-dyed acrylic sliver for outdoor fleece jackets. "What they value is our color consistency and low-carbon attributes," Li Xiong pulled out a scanned copy of the contract on his phone. "The contract specifically states that each batch of goods must be accompanied by a carbon emission test report, which was unimaginable three years ago."

From a small factory in Zhangjiagang to a core supplier of colored acrylic fiber with an annual capacity exceeding 10,000 tons today, Antai Textile Industry has proven over 32 years that "breaking through" in the textile industry is never just about scale expansion, but more about敏锐ly capturing technological trends and making a firm choice for green development. As Director Huang often says: "Every roll of acrylic sliver in the workshop must have a 'sense of the future' – making clothes look good while making the earth feel lighter."

Currently, as dope dyeing technology accelerates its penetration in the textile industry, Antai Textile Industry's R&D team is tackling "bio-based color masterbatch", planning to launch a series of degradable dope-dyed acrylic fiber next year. On this path of green transformation, this established textile enterprise is running towards a "zero-carbon" future with the industry, in a lighter posture.
