Custom Waterproof Polyester Apparel Fabric

For polyester products with special structures (such as zippers with loose weaving structures), how to avoid heat shrinkage during the waterproofing process and keep the appearance and size of waterproof polyester clothing fabrics stable?

In the coating industry, Jintang Coating Co., Ltd., as a benchmark enterprise for special rectification in Shengze Town, has always been committed to technological innovation and environmentally friendly production. It has not only achieved an annual production of more than 20 million meters of various types of coated fabrics in terms of production scale, but also made remarkable achievements in product quality and process optimization. For polyester products with special structures (such as zippers with loose weaving structures), how to avoid heat shrinkage during the waterproofing process and keep the appearance and size of waterproof polyester clothing fabrics stable, Jintang Coating Co., Ltd. has taken the following series of scientific and effective measures:
1. Refinement of pre-treatment process
In the pre-treatment stage, Jintang Coating Co., Ltd. strictly cleans and pre-treats polyester products. This step is crucial because it can effectively remove residual auxiliaries, dyes and other impurities on the surface of the ribbon, laying a solid foundation for subsequent waterproofing processing. The company uses advanced cleaning equipment and processes to ensure that the surface of polyester products is clean and free of dirt, thereby avoiding the problem of waterproof spots caused by impurities sticking to the roller during the waterproofing process. In addition, through refined pre-treatment, the water absorption of fabrics can be enhanced, the penetration effect of waterproofing agents can be improved, and a good foundation for improving waterproof performance can be laid.
2. Selection and application of low-temperature waterproofing agents
For special structural polyester products such as zippers with loose weaving structures, Jintang Coating Co., Ltd. pays special attention to the selection of waterproofing agents. After long-term research and development and testing, the company finally selected low-temperature waterproofing agents such as Texnology® FCB060. This type of waterproofing agent has the characteristics of cross-linking and film formation at a lower temperature (such as 110°C), which effectively solves the problem of heat shrinkage caused by high-temperature processing. Texnology® FCB060 not only has good processing stability, but also does not contain harmful substances such as PFOS and PFOA, and meets EU export standards. It has excellent stability and compatibility, does not affect the original color and breathability of the fabric, and can be mixed with finishing auxiliaries such as softeners, which further improves the comprehensive performance of the product.
3. Optimization of waterproofing processing technology
During the waterproofing process, Jintang Coating Co., Ltd. adopts advanced low-temperature waterproofing processing technology to ensure that the processing temperature is always controlled below the glass transition temperature of special structural materials such as zippers, thereby effectively avoiding the occurrence of heat shrinkage. The company also ensures that the waterproofing agent can evenly penetrate into the fabric fiber to form a solid waterproof layer by precisely controlling the processing time, temperature and concentration of the waterproofing agent. At the same time, the company is also equipped with advanced online monitoring equipment to monitor various parameters in the processing process in real time to ensure stable and reliable product quality.
4. Strengthen quality control and testing
Jintang Coating Co., Ltd. is well aware of the importance of quality control to product performance, so it has established a strict quality control system in the waterproof processing process. The company has set up a special quality inspection department to conduct strict inspections on the appearance size, waterproof performance, air permeability and moisture permeability of each batch of products. Through scientific testing methods and strict quality control standards, the company ensures that each waterproof polyester clothing fabric can meet the established quality standards and meet the diverse needs of customers.
5. Continuous technological research and development and innovation
As a benchmark enterprise in the coating industry, Jintang Coating Co., Ltd. has always regarded technological research and development and innovation as the core driving force for corporate development. The company has a research and development team composed of industry experts and senior technicians, dedicated to the in-depth research and exploration of waterproof coating technology. Through continuous technological innovation and practical application, the company has successfully developed a series of waterproof coating technologies and products with independent intellectual property rights, contributing to the sustainable development of the industry.
In the waterproofing process, Jintang Coating Co., Ltd. has effectively avoided the occurrence of heat shrinkage and maintained the appearance and size stability of waterproof polyester clothing fabrics through refined pre-treatment procedures, selection and application of low-temperature waterproofing agents, optimization of waterproofing processing technology, strengthening quality control and testing, and continuous technical research and development and innovation for polyester products with special structures (such as loose woven structures). These measures have not only improved the comprehensive performance and market competitiveness of the products, but also laid a solid foundation for the company's sustainable development.
