With the increasing pursuit of green sustainable development and healthy life today, Shanghai Jiecon Chemical Hi-Tech Co., LTD. (hereinafter referred to as "Jiecon"), with its profound scientific research strength and unremitting innovation spirit, successfully developed a revolutionary textile photocatalytic finishing agent and submitted an invention patent on August 4, 2022.

In September 2024, Shanghai Jiecon Chemical Hi-Tech Co., LTD. (referred to as Jiecon) and Shanghai Guofan Chemical New-Material Co., LTD., jointly applied for the invention patent "Fabric deodorant finishing liquid, its application and photocatalytic deodorant fabric manufacturing method" was authorized.

First, innovative science and technology, enabling the new future of textiles

Photocatalyst (photocatalyst) after absorbing sunlight or ultraviolet light source, oxidation and reduction reactions occur, producing hydroxyl free radicals and superoxygen free radicals, which can react with organic matter and cut off the molecular binding of organic matter (C-C, C-H, C-N, C=O, N-H, etc.). Decompose the harmful substances and microorganisms in the air into harmless carbon dioxide and water, as shown in the following figure:

This photocatalytic finishing agent is the crystallization of Jiecon's scientific research team after several years of dedicated research and repeated trials. It cleverly combines photocatalyst technology and textile finishing process, through the uniform adhesion of nano-scale photocatalyst particles, unprecedented to give textiles self-cleaning, antibacterial, antiviral, deodorization and air purification comprehensive capabilities. Under light conditions, these tiny and powerful particles can continue to decompose harmful substances in the air, such as formaldehyde, TVOCs (total volatile organic compounds) and bacteria and viruses, creating a healthier and cleaner living environment for consumers.

According to the market demand and customer needs, Jieccon timely developed a photocatalytic finishing agent that can play a good role under visible light and ultraviolet conditions for the development of related textiles. The following is the performance test of the developed photocatalytic finishing agent applied to textiles:

1. Antibacterial performance of photocatalyst under visible light (Chinese national standard)

According to the Chinese national standard GB/T 30706-2014 "Antibacterial test methods and evaluation of photocatalytic antibacterial materials and products under visible light irradiation", the antibacterial rate of Staphylococcus aureus and Escherichia coli in the test samples was 99%, and the light contribution rate was 67%. The test shows that the fabric treated with the photocatalyst finishing agent developed by our company has good antibacterial properties and good washing resistance under visible light conditions.

Note: for details about test conditions, see the test report.

2. Antibacterial performance of photocatalyst under ultraviolet (Chinese national standard)

According to the Chinese national standard GB/T 23763-2009 "Evaluation of antibacterial properties of photocatalytic antibacterial materials and products", the antibacterial rate of Staphylococcus aureus was greater than 99% ,and Escherichia coli in the test samples was  99% (ultraviolet light contribution value 80%). The test shows that it has more obvious antibacterial properties and good washing resistance under ultraviolet conditions.

Note: for details about test conditions, see the test report.

3. Antibacterial performance of photocatalyst under ultraviolet (Japanese standard)

According to JIS R 1702:2020 ガラス close adhesion method (under ultraviolet), the antibacterial activity value of Staphylococcus aureus in the test sample was 3.6, and the antibacterial activity value of photocontribution was 1.9. The antibacterial activity of Bacillus pneumoniae was 3.6, and the antibacterial activity of photocontribution was 1.0. The test results show that the fabric treated with the photocatalytic finishing agent developed by our company has obvious photocatalytic activity, can produce good antibacterial action, and has good washing resistance.

Note: for details about test conditions, see the test report.

4, Photocatalyst deodorization performance under UV conditions (Japanese standard)

According to the Japan standard: 纎維評価技術協議会 SEKマ一ク纎維製品認証基準22.光触媒消臭性試(检知管法)（紫外线条件下） the test sample under bright conditions of ammonia deodorization rate is 99%, the photocatalyst effect is 38%; The deodorization rate of acetaldehyde was 98%, and the photocatalytic effect was 84%. The test results show that the fabric treated with the photocatalytic finishing agent developed by our company has obvious photocatalytic activity, can produce good deodorization effect, and has good washing resistance.

Note: for details about test conditions, see the test report.

5. Antiviral performance of photocatalytic finishing agent (refer to ISO 18184-2019)

The fabrics treated with photocatalytic finishing agent were tested for anti-virus, and the test results were as follows:

    The antiviral activity rate of the photocatalyst treated fabric against influenza virus H1N1 (envelope virus) was >99.99%, and it had excellent antiviral performance.

The antiviral activity rate of the photocatalyst treated fabric against enterovirus EV71 (non-coated virus) was 96.77%, and it also had good antiviral performance.

It can be seen from the above test data that under visible light conditions, the photocatalyst finishing agent has good antiviral performance against the representative viruses including the enveloped viruses and non-enveloped viruses. This shows that the photocatalytic finishing agent developed by our company has a good antiviral activity rate against viruses under visible light conditions.

Second, green and healthy, leading the new trend of consumption

With the increasing attention of consumers to healthy life, green, environmentally friendly and functional textiles have become the new darling of the market. The advent of Jiecon photocatalyst finishing agent not only meets the market demand for high-quality textiles, but also reduces the use of chemical detergents, reduces water consumption and environmental pollution in the washing process, and truly realizes the whole green process from production to use.

Third, wide application, open unlimited possibilities

The finishing agent can be widely used in all kinds of textiles, including clothing, home textiles, curtains, carpets, etc., effectively improve the added value of products and market competitiveness. Whether it is the daily use of family wear, or the decorative fabric in public places, you can enjoy the health protection brought by photocatalytic technology. In addition, its excellent washable resistance and durability ensure the long-term effectiveness of the finishing effect and bring continuous health protection to consumers.

Fourth, look to the future, continuous innovation

In the future, Jiecon will continue to deepen the field of textile chemicals, constantly explore the application of new technologies and new materials, and is committed to providing consumers with more safe, healthy and environmentally friendly textile product solutions, contributing to the green and sustainable development of China's textile industry. We look forward to the rapid popularization of this scientific and technological achievement, the benefit of thousands of households, and jointly protect our blue sky and white clouds and a better life.
