Research and Application of Green Fiber Fabrics: A Development Direction Under the Environmental Trend

Against the backdrop of the global push for "dual carbon" goals and the widespread adoption of environmental protection concepts, the green transformation of the textile industry has become an inevitable trend. As a core raw material in the textile industry, chemical fiber fabrics face numerous challenges in their traditional production models, including high resource consumption and severe environmental pollution, making green upgrading imperative. Green fiber fabrics, based on environmentally friendly raw materials and supported by green processes, combine the superior performance of traditional chemical fiber fabrics with environmentally friendly characteristics, becoming a key direction for breaking through industry development bottlenecks and meeting the demands of market consumption upgrades. This article systematically reviews the core research and development directions, key technological breakthroughs, and diverse application scenarios of green fiber fabrics, and looks forward to future development paths under the environmental trend, providing a reference for the high-quality development of the industry.

I. Policy and Market Dual Drivers for the Development of Green Fiber Fabrics

The rapid development of green fiber fabrics is inseparable from the dual empowerment of policy guidance and market demand, forming a virtuous cycle of "policy setting the direction and market promoting implementation." From a policy perspective, various countries have introduced relevant policies to promote the green transformation of the textile industry, providing clear guidance for the research and application of green fiber fabrics. Domestically, the "Guiding Opinions on High-Quality Development of the Chemical Fiber Industry" explicitly proposes building a clean, low-carbon, and circular green manufacturing system, expanding green fiber production, and promoting the average annual growth of bio-based chemical fiber and biodegradable fiber materials, elevating greening to a strategic level for industry development. Internationally, the EU's REACH regulations and green tariffs, among other environmental policies, are continuously being upgraded, imposing higher requirements on the environmental indicators of textile products and forcing companies to increase their R&D investment in green chemical fiber fabrics. From a market demand perspective, consumption upgrades are driving increasing environmental awareness among end consumers, making green, healthy, and sustainable textile products new market favorites. In the apparel sector, demand for environmentally friendly fabrics continues to grow in categories such as sportswear and underwear; in the home textile sector, antibacterial, anti-mite, and biodegradable green home textile fabrics are gaining popularity among families; and in the industrial sector, the application demand for environmentally friendly chemical fiber fabrics in scenarios such as medical protection and automotive interiors is gradually expanding. Simultaneously, many brand companies are actively developing green supply chains, using green chemical fiber fabrics as an important indicator of brand sustainable development, further boosting market demand for green chemical fiber fabrics and providing ample space for their R&D and application.

II. Core R&D Directions and Technological Breakthroughs in Green Fiber Fabrics The core of green fiber fabric R&D lies in achieving "full life-cycle greening," meaning that environmental impact can be effectively reduced at every stage, from raw material selection and production processes to recycling. Currently, the industry focuses on three core directions: bio-based fibers, recycled fibers, and green production processes, continuously breaking through key technological bottlenecks to promote the quality upgrade and large-scale application of green fiber fabrics.

1. Bio-based Fiber Fabrics: The Core Path to Raw Material Substitution Bio-based fiber fabrics use renewable biomass as raw materials to replace traditional fossil-based raw materials, reducing dependence on non-renewable resources at the source, which is an important direction for green fiber fabric R&D. These raw materials mainly include plant starch, straw, fungi, and bio-fermentation products, which are used to prepare fiber monomers through biosynthesis technology and then processed into fabrics, offering significant low-carbon and environmentally friendly advantages. Currently, the R&D of bio-based polyester, bio-based nylon, polylactic acid (PLA), and lyocell bio-based fiber fabrics has achieved phased breakthroughs. In terms of technological breakthroughs, the industry focuses on overcoming the efficient preparation and large-scale production technologies of bio-based raw materials. For example, optimizing bio-fermentation strains through genetic engineering can improve the yield and purity of bio-based monomers, reducing production costs. Developing green spinning technologies such as ionic liquid solvent methods and low-temperature urea methods solves the solvent pollution problem in traditional spinning processes, improving the quality stability of bio-based chemical fiber fabrics. Some bio-based chemical fiber fabrics have already achieved industrial application, demonstrating outstanding performance in terms of skin-friendliness, softness, moisture absorption, and quick-drying properties, while also possessing good biocompatibility and biodegradability, making them suitable for high-end clothing, medical textiles, and other fields.

2. Regenerated Chemical Fiber Fabrics: A Key Support for Resource Recycling Regenerated chemical fiber fabrics are made from waste textiles, plastic bottles, waste silk, and other waste materials through recycling, sorting, and reprocessing processes, achieving resource recycling and serving as an important carrier for practicing the circular economy concept. Currently, the research and development focus of recycled chemical fiber fabrics is on technological upgrading and quality improvement, aiming to solve problems such as high impurity levels, unstable performance, and limited application scenarios in traditional recycled fabrics. In terms of technological breakthroughs, firstly, recycling and sorting technologies have been optimized. Intelligent sorting equipment improves raw material purity, separating different types of fibers and impurities to provide high-quality raw materials for subsequent processing. Secondly, spinning and weaving processes have been improved, employing technologies such as efficient melt spinning and precision stretching to enhance the strength, toughness, and uniformity of recycled fibers, narrowing the quality gap with virgin synthetic fiber fabrics. Thirdly, a full-chain traceability system has been established, using technological means to achieve full traceability of the source of recycled raw materials and the production process, enhancing product credibility. Recycled polyester, recycled nylon, and other fabrics have been widely used in clothing, home textiles, and industrial textiles, forming a closed-loop cycle of "waste - recycled raw materials - synthetic fiber fabrics - end products."

3. Green Production Processes: The Core Guarantee for Process Emission Reduction The development of green synthetic fiber fabrics not only relies on raw material innovation but also requires process innovation throughout the entire production process. By adopting energy-saving and emission-reduction technologies, environmentally friendly additives, and clean production equipment, energy consumption and pollutant emissions during production are reduced. In the dyeing and finishing process, environmentally friendly processes such as waterless dyeing, low-temperature dyeing, and biodegradable dyes have been widely promoted. Waterless dyeing technology can significantly reduce water consumption and wastewater discharge, low-temperature dyeing technology can reduce energy consumption, and biodegradable dyes can reduce chemical pollutant residues. In the spinning process, raw material loss and energy consumption are reduced by optimizing process parameters and adopting high-efficiency and energy-saving equipment. At the same time, the technology for recycling and utilizing waste gas and waste residue in the production process is also constantly being improved to achieve efficient utilization of energy and resources.
