1. Green transformation of the textile industry: the transformation from pollution to environmental protection
As the world’s second largest source of pollution, the textile industry’s impact on the environment cannot be underestimated. During the traditional textile production process, dyeing, printing and other processes discharge a large amount of wastewater containing heavy metals and toxic chemicals to the water every year. These pollutants not only seriously threaten the aquatic ecosystem, but also affect human health through the food chain. At the same time, the widespread use of synthetic fibers has led to increasingly serious pollution of microplastics, which has become an environmental issue of global concern.
Pursuant to the concept of sustainable development, the textile industry is undergoing an unprecedented green transformation. Governments of various countries have successively issued strict environmental protection regulations to limit the use of harmful chemicals and promote the application of clean production technology. International norms such as EU REACH regulations and US EPA standards have set higher environmental protection thresholds for textile production. Enterprises are no longer satisfied with simple compliance requirements, but instead actively seek innovative solutions to reduce the environmental footprint in the production process.
The market demand for green textiles is growing rapidly. Consumers are increasingly inclined to choose environmentally certified products, which prompts brands and manufacturers to revisit production processes and raw material choices. Many leading companies have begun to adopt a circular production model to reduce resource consumption and waste generation through technological innovation. For example, the use of recycled fibers has increased year by year and the widespread promotion of low-energy production equipment has been marked by the textile industry’s move towards a more sustainable development path.
However, this transformation process was not smooth. While pursuing environmental protection, enterprises also need to balance cost control and product quality, which puts higher requirements on technological research and development. Especially in the field of functional textiles, how to achieve environmental protection goals while maintaining product performance has become a key issue that the industry needs to solve urgently. This also provides broad space for the research and development of new environmentally friendly additives.

The major feature of composite anti-yellowing agent is that its comprehensive performance is superior and can provide comprehensive protection under various conditions, but its preparation process is relatively complex and the cost is high.
It is worth noting that the selection of different types of anti-yellowing agents requires consideration of specific use environment and processing conditions. For example, in outdoor environments with strong light, products with strong ultraviolet absorption capacity should be preferred; while in high-temperature processing environments, antioxidant products with better heat resistance should be selected. Through reasonable combination and optimized use, the advantages of various anti-yellowing agents can be fully utilized to achieve excellent protective effects.
IV. The mechanism and performance of bust anti-yellowing agent
The reason why bust anti-yellowing agent can shine in the field of textile protection is due to its unique molecular structure and multiple mechanisms of action. This chemical builds a comprehensive protective barrier through various methods such as physical adsorption, chemical bonding and free radical capture, effectively resisting various factors that cause yellowing.
Photoprotection mechanism
The key UV absorbing component in the anti-yellowing agent can convert high-energy UV light into harmless thermal energy release through ?-?* electron transition. Specifically, when ultraviolet rays irradiate on the surface of a textile, the conjugated system in the anti-yellowing agent molecule quickly captures photon energy and dissipates the energy through a non-radiative transition process. This process can be expressed by the following chemical equation:
[ text{UV} + text{Absorber} rightarrow text{Excited Absorber} rightarrow text{Heat} ]
This photoprotection mechanism not only prevents the damage of ultraviolet rays to the polymer backbone, but also prevents the free radical chain reaction caused by light, thereby fundamentally eliminating the occurrence of photoyellowing.
Oxygen Protection Mechanism
Antioxidation components interrupt the oxidation chain reaction by sacrificing themselves. When oxygen molecules react with polymers to form peroxide radicals, the antioxidant will react with them quickly to form a stable product, terminating the propagation of the chain reaction. The typical reaction path is as follows:
[ ROOcdot+ AO rightarrow ROOH + AOcdot ]
[ AOcdot + Rcdot rightarrow Stable Products ]
This dual protection mechanism allows anti-yellowing agents to maintain the color stability of the textile for a long time. Experimental data show that under standard accelerated aging test conditions (50°C, 80% humidity, ultraviolet lamp irradiation), the yellowing index of samples with anti-yellowing agent can be reduced by more than 70% compared with the untreated samples.
Performance Evaluation Metrics
In order to quantify the actual effect of anti-yellowing agents, the industry usually uses the following key indicators for evaluation:
| Performance metrics |
Test Method |
Reference value range |
| Yellow Index (YI) |
ASTM D1925 |

Through these standardized tests, the actual effect of anti-yellowing agents under different usage conditions can be accurately evaluated. Especially for underwear products, due to their close contact with human skin, special attention is also needed to pay attention to the biocompatibility and safety of the product. Relevant studies have shown that the optimized formula anti-yellowing agent can not only effectively prevent yellowing, but also maintain the original softness and breathability of the material, meeting the functional needs of high-end textiles.
5. Current market application status and challenges of bust anti-yellowing agent
The application of bust anti-yellowing agents in the global textile market shows significant regional differences and diversification trends. In developed countries in Europe and the United States, due to strict environmental protection regulations and consumers’ high requirements for product quality, the market demand for anti-yellowing agents continues to grow. According to statistics, the European market demand for yelitising agents in 2022 has exceeded 20,000 tons, of which Germany, France and Italy are the main consumer countries. Companies in these regions generally use composite anti-yellowing agents, focusing on the environmental characteristics and safety of the products.
In contrast, the Asian market has shown greater development potential.

According to industry statistics, China’s anti-yellowing agent production in 2022 will reach about 45,000 tons, of which about 60% will be used for export. The demand for functional additives in emerging textile industry centers such as Vietnam and Bangladesh is also rising rapidly, and it is expected to maintain an average annual growth rate of 12% in the next five years.
However, market development also faces many challenges. First of all, there is a problem of technical barriers. The research and development of high-performance anti-yellowing agents requires breakthroughs in a number of key technical bottlenecks. For example, how to improve the migration resistance of a product is a difficult point. Although the mobility of mainstream products on the market has dropped below 0.5%, it is still difficult to meet the requirements of some high-end applications. The second is environmental pressure. With the increasing strict global control of chemicals, the development of green and degradable anti-yellowing agents has become an industry consensus. The latter is a cost control problem. High-performance products are often accompanied by higher manufacturing costs, which to a certain extent limits their promotion and application in the low-end market.
To address these challenges, the industry is actively exploring new solutions. On the one hand, reduce production costs by improving production processes and raw material selection; on the other hand, strengthen cooperation between industry, academia and research and promote technological innovation. For example, a leading domestic company successfully developed a new generation of composite anti-yellowing agent by introducing nanodispersion technology. Its performance indicators have reached the international advanced level and achieved significant cost advantages. This technological breakthrough not only enhances the market competitiveness of domestic products, but also injects new vitality into the development of the industry.
6. Technological innovation and future development of bust anti-yellowing agent
The technological progress of bust anti-yellowing agent has always been closely linked to the overall development trend of the textile industry. In recent years, with the rapid development of nanotechnology, smart materials and green chemistry, a series of innovative achievements have emerged in the field of anti-yellowing agents. These new technologies not only improve product performance, but also create possibilities for their application in a wider range of fields.
Breakthrough Application of Nanotechnology
The development of nanoscale anti-yellowing agents is one of the key directions of current research. By preparing the active ingredient into nanoparticles, its dispersion and compatibility can be significantly improved. Studies have shown that anti-yellowing agents with particle sizes in the range of 20-50nm have excellent protective effects. This nano-scale product not only maintains the excellent performance of traditional products, but also greatly reduces mobility and precipitation tendency. More importantly, the application of nanotechnology allows anti-yellowing agents to synergize with other functional additives (such as antibacterial agents and anti-mite agents), providing new ideas for the development of multifunctional textiles.
Intelligent Responsive Anti-Yeling Agent
Responsive anti-yellowing agent developed based on the principle of intelligent materials is another important development direction. This type of product can automatically adjust its protective performance according to changes in environmental conditions. For example, certain pH-responsive anti-yellowing agents enhance their activity in sweat environments, thereby better protecting textiles from yellowing caused by sweat stains. Temperature-responsive products can release more active ingredients under high temperature conditions.Provides stronger protection for textiles. This intelligent feature allows anti-yellowing agents to function more accurately and improve their use efficiency.
Practice of Green Chemistry
In the context of increasingly stringent environmental protection requirements, significant progress has been made in the research and development of degradable anti-yellowing agents. By using bio-based raw materials and renewable resources, researchers have developed a range of environmentally friendly products. For example, natural anti-yellowing agents prepared with plant extracts not only have good protective effects, but also exhibit excellent biodegradable properties. While meeting functional needs, these green products greatly reduce the impact on the environment.
Looking forward
With the continuous advancement of technology, anti-yellowing agents are expected to achieve breakthrough applications in more fields. In the field of medical textiles, anti-yellowing agents can be combined with medical dressings to extend the service life of the product; in the field of aerospace, their special protective properties can be used for the treatment of high-performance fibers; in the field of building decoration materials, they can provide long-lasting color protection for functional fabrics. These emerging applications will bring broader market space and development opportunities to the anti-yellowing agent industry.
7. Environmental protection significance and social responsibility of bust anti-yellowing agent
Bust cotton anti-yellowing agent plays a crucial role in promoting the green development of the textile industry. This chemical not only helps to extend the service life of textiles and reduce resource waste, but also reflects its environmental value and social responsibility at multiple levels. First, by effectively preventing yellowing, anti-yellowing agents can significantly reduce the possibility that textiles will be eliminated in advance due to appearance deterioration. It is estimated that the rational use of anti-yellowing agents can extend the average service life of textiles by more than 30%, which means millions of tons of textile waste production can be reduced every year.
From the energy consumption point of view, the application of anti-yellowing agents also helps to reduce the carbon footprint of the textiles throughout their life cycle. Due to the extended service life of the product, the necessity of frequent replacement and reproduction is reduced, thus saving a lot of energy consumption. Especially for high-energy-consuming materials such as polyurethane foam, this energy-saving effect is more significant. Data shows that the use of anti-yellowing agents can indirectly save about 10 tons of energy consumption of standard coal, which is equivalent to reducing carbon dioxide emissions by 25 tons.
In terms of water resource protection, anti-yellowing agents also play a positive role. By extending the use cycle of textiles, the washing water demand caused by product scrap can be effectively reduced. Taking underwear products as an example, if all bra products around the world can be treated with high-quality anti-yellowing agents, billions of cubic meters of water can be saved every year. This water-saving benefit is particularly important in areas with water scarcity.
In addition, the research and development of modern anti-yellowing agents is increasingly focusing on green and environmentally friendly characteristics. Many new products adopt biodegradable raw material systems to avoid environmental pollution problems that traditional chemicals may cause. For example, some anti-yellowing agents based on plant extracts not only have excellent protective properties, but also can quickly in natural environmentsQuickly decompose without lasting pollution. This “from cradle to cradle” design concept fully reflects the social responsibility of chemical research and development.
It is worth stressing that the use of anti-yellowing agents can also indirectly promote the development of the circular economy. By improving the durability and recyclability of textiles, more favorable conditions are created for the reuse of used textiles. This virtuous cycle not only helps alleviate resource pressure, but also drives the upgrading and development of related industrial chains and creates more employment opportunities and economic value for society.
