China Fiber Fashion Trends is an important industry event jointly organized by the China Chemical Fiber Industry Association, Donghua University, China National Cotton Textile Association and Tongkun Group Co., Ltd. under the guidance of the Department of Consumer Goods Industry of the Ministry of Industry and Information Technology. This event aims to promote the application of new fiber materials among downstream manufacturers and brands, facilitate in-depth cooperation between the upstream and downstream of the industrial chain, encourage enterprises to continuously break through in the field of fiber innovation and application, and lead the trend of the global fiber industry.
As the authoritative release platform of China's fiber industry, China Fiber Trends selects a group of enterprises that have performed outstandingly in technological innovation, market application, brand building and other aspects every year to become the annual partners. These enterprises are not only the trendsetters of the industry, but also an important force driving Chinese fibers to go global.

Company Profile

Since its establishment, Shanghai Jiecon has always adhered to innovation-driven development and quality as the core, and is committed to providing high-performance and high-quality chemical fiber products for global customers. The company is equipped with advanced production facilities and a technical R&D team, specializing in the research and application of chemical fiber materials. Its products are widely used in multiple fields such as clothing, home textiles, and industry.

Product Introduction

 Fabrics or clothing woven from heat-shielding fibers/yarns have certain heat-shielding properties. By reducing the impact of solar radiation on the perceived temperature, they prevent heat from being transferred to the human body surface, thereby providing the wearer with a comfortable and heat-shielding feeling.
The evaluation of the heat insulation performance of textiles is also of great significance. It is an important means to assess the heat insulation performance of textiles by quantitatively analyzing the technical parameters of thermal characterization of textiles and the experimental results of thermal performance, as well as comprehensively evaluating the overall performance of the heat insulation performance of textiles. Generally, the evaluation of the heat insulation performance of textiles can be divided into three parts: the first is the quantitative analysis of thermal physical performance parameters, the second is the assessment of thermal experiments, and the last is the comprehensive evaluation.
Generally speaking, the fabric heat shielding process mainly involves coating a layer of heat shielding material on the fabric or applying heat shielding technology to achieve the effect of reducing heat conduction and radiation. Heat-shielding materials usually have a high reflectivity, which can reflect most of the thermal radiation and reduce heat absorption. Heat insulation technology can also form an insulating film on the surface of the fabric to prevent heat conduction and improve the heat insulation performance of the fabric.

However, the heat-shielding fabric obtained through the above-mentioned method is not breathable when worn, has poor comfort and a worse user experience. For this reason, in response to the demands of the market and relevant customers, our company has developed high-efficiency heat-shielding polyester masterbatches and fibers/yarns.

 Compared with similar products on the market, the color of the light-absorbing and heat-generating polyester masterbatch developed by our company is lighter, as shown in the following figure:

Our company, in collaboration with downstream cooperative units, has carried out the development of heat-shielding polyester yarns and related fabrics. The fabric specifications are as follows:

The fabric specifications and structure are as follows: The weaving process of cotton-polyester thermal insulation fabric (C40s/T40s (thermal insulation yarn),C60%/T40%; 100*68 Weight per gram: 100gsm.
This fabric was sent to BOKEN for inspection. The test results are as follows:

Our company also collaborates with post-processing polyester DTY manufacturers to develop heat-shielding polyester DTY yarns (75D/72F), as shown below (the color is also relatively light) :

 As can be seen from the above, the heat-shielding fabric woven from heat-shielding fibers and yarns developed by our company has a relatively high heat-shielding performance. It will be well applied in outdoor fabrics, workwear fabrics and other uses in the future.

With the power of technology, set a new benchmark for green textiles

Being shortlisted as a partner of China Fiber Trends 2025/2026 is a high recognition of the achievements Shanghai Jiecon has made in the application of new fiber materials. The company has not only been deeply engaged in the traditional chemical fiber field for many years, but will also actively lay out emerging fields such as green and environmentally friendly fibers and functional fibers in the future, promoting the development of the chemical fiber industry towards a more sustainable and intelligent direction.
This shortlisting marks that Jiecon's research and application in the field of antimony-free environmental protection materials have reached the leading level in China, and also indicates that we have taken a solid step forward on the road to promoting the green transformation of the textile industry. We firmly believe that technological innovation is the inexhaustible driving force for the progress of the industry. Jiecon will continue to explore, constantly break through, and lead the new trend of future fiber materials!
