A worn jacket, a piece of leftover fabric cut from a clothing factory, or a set of replaced home textiles are often thrown into the trash can and eventually end up in landfill or incineration. For a long time, how to stably and economically restore these waste polyester textiles with complex components and various colored dyes into high-quality new fibers, and build a commercially viable "Textile to Textile" (T2T) closed-loop production line, has been a difficult problem for the global textile industry for many years.
Anhui Xindengli Environmental Protection Technology Co., LtdIt is one of the companies that solves this problem. Relying on the independently iterated ethylene glycol alcoholysis BHET (dihydroxyethyl terephthalate) core process and exclusive melt direct spinning regeneration technology, the enterprise has truly opened up the full commercial chain of "waste textiles monomer reduction primary grade fibers", allowing T2T chemical regeneration technology to bid farewell to conceptualization and achieve large-scale, stable, and market-oriented mass production.
Newdenly, which has just concluded the 2026 Yarn Expo autumn and winter yarn exhibition, has not stopped in its footsteps. It will showcase its T2T chemical regeneration technology and innovative products at the 3rd Asia Pacific Textile and Clothing Supply Chain Expo (APTEXPO 2026) from November 11-13, 2026, presenting the Newdenly solution of "growing new fibers from waste" to the global supply chain.
Deeply cultivate inward,
Overcoming the barriers of T2T cycle technology
The rapid growth of Anhui Xindengli Environmental Protection Technology Co., Ltd. from scratch to rapid rise was not achieved overnight. The enterprise has been deeply involved in the T2T recycled textile field for many years, and its business layout has undergone iterative upgrades. Nowadays, the factory located in Jinzhai County Economic Development Zone, Lu'an, Anhui covers an area of more than 200 acres, with an overall melt production capacity of 110000 tons per year.
T2T stands for Textile to Textile, which is a closed-loop recycling model of "waste textiles - new textiles".
Different from the traditional physical regeneration path using plastic bottle fragments as raw materials, Xindengli's T2T chemical regeneration technology is fully compatible with various types of waste textile materials such as waste clothing, home textile fabrics, and scraps generated in the production process of clothing factories and weaving factories. Through chemical molecular level reduction regeneration, it replaces inefficient treatment methods such as incineration and landfill, and maximizes the residual value of waste textile materials. ”Liu Ning, Marketing Director of the CompanyIntroduction.
Behind this mature mass production system is the company's years of technological accumulation and repeated trial and error. From 2019 to 2022, Xindengli had already laid out in Jinzhai, but at that time, the regeneration process was not yet mature and the project could not be put into actual operation; In 2022, there will be a turning point. With the iteration of artificial intelligence and the landing of mature process packages, the enterprise has completed a new round of systematic technical demonstration, confirming that the T2T chemical regeneration process is feasible for mass production; In 2023, the BHET chemical regeneration core process and technology package will be implemented, and the project will truly take root.
In the following two years, the team immersed themselves in the repeated debugging and optimization of the BHET ethylene glycol alcoholysis process until the mass production line operated stably. ”Liu Ning stated that the BHET ethylene glycol alcoholysis process is a core technology of the enterprise and a breakthrough process in the industry.
The scientific basis of this process lies in the precise bonding of the chemical structure of PET (polyethylene terephthalate) polyester - PET is formed by the condensation of "ethylene glycol (EG)+terephthalic acid (PTA)". Through the reverse depolymerization reaction of ethylene glycol alcoholysis, the ester bonds of waste polyester polymer chains are selectively broken and gradually depolymerized into BHET (dihydroxyethyl terephthalate) monomers, which are then purified, re polymerized, and spun into shape. By following the chemical properties of polyester materials themselves, molecular level "recycling" is achieved, which has lower energy consumption and stronger environmental friendliness compared to traditional pathways.
Relying on this core process, the enterprise has once again broken through the industry bottleneck, implemented melt direct spinning technology, and broken the traditional process of "slicing and spinning" in the industry - eliminating the intermediate granulation (slicing) transfer link. Qualified regenerated melt can be directly spun into shape, greatly reducing production costs while maximizing the retention of fiber properties, and significantly improving the stability of finished product quality. This is also a scarce core technological advantage among domestic mass-produced enterprises in the same field.
Technological mass production is the foundation, and stable and high-quality raw material supply is the lifeline for the large-scale development of T2T chemical regeneration technology industry. At the beginning of the establishment of the enterprise, it was clear that the production line must adapt to non-standard raw materials with complex components and dispersed sources. If only high-quality raw materials on the market can be used, the circular textile industry will never be truly standardized, "said Liu Ning. To solve the problem of raw materials, Xindengli has established a dual track supply chain system of "head platform centralized procurement+local industry support", while relying on self-developed technology to achieve deep purification of the backend, breaking down barriers to waste textile recycling from the source to the entire production process.
The front-end classification and sorting establish a solid foundation, while the back-end core process completes quality assurance. In response to the two major processing difficulties of blended fabrics and dyed fabrics, Xindengli has created an exclusive purification system. Liu Ning introduced that for dyed waste fabrics, the company has independently developed an integrated decolorization device, deeply integrated into the ethylene glycol alcoholysis process, which can efficiently remove the original pigments of the fabric without traditional washing and bleaching processes, solving the industry problem of uneven color difference and batch differences in regenerated fibers.
Relying on the advantages of full chain technology and supply chain, the enterprise has created three core product matrices, covering T2T regenerated slicing, T2T regenerated POY/FDY/DTY filament, and T2T regenerated short fiber. At the same time, it has partnered with listed companies to strategically develop regenerated T2T masterbatch and improve the regenerated product system. At present, the enterprise's products have passed LCA full lifecycle certification, RCS T2T chemical regeneration certification, and ISCC automotive industry specific certification, making it one of the few domestic enterprises with 100% certification for chemical regeneration products. The comprehensive qualification certification and stable product quality have enabled Xindanli to successfully enter the international first-line brand supply chain, and the recognition of the high-end market continues to increase.
Expand outward,
Accelerate global market layout
Technological success and stable raw materials are just the starting points. When recycled fibers move from the laboratory to the shelves, they face even more complex and demanding market-oriented tests: waste textiles are disassembled, restructured, and reshaped at the molecular level to return to the industry chain in a completely new fiber form. The core issue that the industry is most concerned about is always the "performance benchmark" - whether the spinning stability, dyeing uniformity, and other key indicators of recycled fibers can be compared to mature native polyester products?
Regarding this, Liu Ning stated that the core properties of T2T chemically regenerated fibers are infinitely close to the quality of native polyester, and the quality stability is far superior to traditional physically regenerated products. Its core advantage stems from the unique principle of ethylene glycol alcoholysis reduction reaction: it can completely dismantle the complex polymer molecular structure of waste textile products, reduce them to the initial monomer state close to petrochemical raw materials, and then re polymerize and spin them to produce new fibers, thereby achieving a "primary level" return in performance.
With its excellent quality compared to native polyester, Xindengli T2T recycled fiber can be widely adapted to high-end functional fabrics in multiple categories, achieving the landing of high-end scenes in multiple fields. In the field of automotive interior, the product can be stably applied to core components such as car roofs, seat fabrics, suede like interiors, seat belts, airbags, tire curtains, etc; In the home textile and home furnishing field, the adaptation scenarios are equally broad. Currently, over 80% of high-end home fabrics in the market, such as polyester imitation leather and imitation wool, can be produced using this recycled fiber. The finished products can meet the strict standards of the high-end consumer market in terms of durability, visual texture, and touch feel.
Based on high-quality product performance and mature technology system, Xindengli has anchored its global development positioning since its establishment, building a dual wheel driven globalization strategy of "product going global+technology going global": on the one hand, it strives to promote high-end recycled fiber products to seize the international high-end market, and on the other hand, it actively exports China's independently controllable T2T chemical regeneration core technology, committed to creating a benchmark brand of domestically produced recycled raw materials with global influence.
To solidify the foundation of global cooperation, the company maintains a high-frequency and stable pace of international customer docking for a long time. On average, it receives a group of international first-line brand procurement teams for on-site inspections every one to two weeks. Liu Ning stated that overseas customers will conduct compliance audits on the entire industry chain process of enterprises, from waste material recycling, pretreatment, alcoholysis regeneration, spinning and forming, to finished product testing and factory delivery.
While steadily expanding the market, Xindengli focuses on technological iteration and cost optimization, anchoring two core R&D upgrade directions: comprehensive upgrade of decolorization process and continuous cost reduction of regenerated fiber production, in order to further enhance the market cost-effectiveness and commercial competitiveness of regenerated fibers.
In addition to technological iteration, enterprises are simultaneously increasing their brand promotion efforts both domestically and internationally, relying on various industry exhibitions to showcase core raw material products such as recycled slices, long filaments, and short fibers, and continuously expanding the industry influence and brand awareness of domestic T2T recycling technology. Liu Ning stated that the appearance of APTEXPO 2026 is a crucial step for the company to deepen its presence in the Southeast Asian market and improve its global layout. The exhibition has a high level of internationalization and precise coverage of high-end global buyers, which is highly compatible with Xindengli's high-end and global brand positioning. It can efficiently link international terminal brand resources, fill the gaps in the Southeast Asian regional market, and build high-quality commercial channels for the global penetration of domestic recycled technology and products.
In the future, Xindengli will steadily deepen its global strategic layout and help the domestic circular textile industry move towards the global high-end stage.
