In order to promote the promotion and implementation of the latest textile printing and dyeing technology in domestic textile colleges and universities in Keqiao area, the 2022 Advanced Textile Printing and Dyeing Innovation Forum was successfully held online recently. The guests attending the meeting discussed textileThe innovative development of the printing and dyeing industry, the live broadcast is full of useful information.
It is reported that this event is hosted by the Keqiao District Printing and Dyeing Industry Cluster Upgrading Service Center, hosted by the Keqiao Textile Industry Technology Center of Jiangnan University and the Editorial Department of “Printing and Dyeing Auxiliaries”, and co-organized by the Shaoxing Keqiao Modern Textile Technology Innovation Alliance. The forum invited many professors from Dalian University of Technology, Wuyi University and Jiangnan University to share their latest research results in the field of textile printing and dyeing innovation through special speeches, providing highqualityProvide ideas and suggestions for development.
Professor Zheng Laijiu of Dalian University of Technology gave a report entitled “Key Technologies and Engineering of Supercritical CO2 Waterless Dyeing”, which mainly elaborated on the efforts of Dalian University of Technology in my country to solve the problems of water and air pollution during the dyeing and finishing process. Conduct research on supercritical carbon dioxide fluid anhydrous technology.
Zheng Laijiu said that this technology uses recycled industrial carbon dioxide emissions to dissolve dyes in a supercritical state and dye textiles in a closed kettle, achieving supercritical carbon dioxide fluid-free production of polyester fibers, yarns, and fabrics. The engineering production of water dyeing has the advantages of high color fastness, short process, no three waste emissions, and the recycling of dyes and carbon dioxide. At the same time, compared with traditional water medium dyeing, supercritical carbon dioxide fluid dyeing consumes no water, does not require rinsing and drying; carbon dioxide is non-toxic, non-flammable and low-priced; dyeing does not require additives and the dye cost is low, truly solving the root cause of dyeing. The comprehensive water pollution problem fully embodies the modern processing concept of clean, green and low-carbon.
Professor Yu Hui of Wuyi University gave a report on “Development of New Multifunctional Medical Dressing Products”. He said that a multifunctional nanofiber scaffold with a 3D structure was developed using technologies such as electrospinning, microfluidic spinning, 3D printing and sustained release of drug-loaded nanoparticles. , platelet-rich bioactive hydrogel fiber network and a series of high-end modern medical dressings to achieve coordinated and controlled release of multiple functional drug molecules. The development of this product can break through the limitations of the short life cycle of active materials in active medical dressings, and can be successfully used in the treatment of chronic wounds such as full-thickness chronic wounds and diabetic foot ulcer wounds, driving the domestic medical dressing industry to gradually shift to the mid-to-high end.
“The advantage of foam dyeing and finishing is that air is used as a carrier instead of water as a transmission medium, reducing the use of dyes and other dyeing and finishing auxiliaries, saving the cost of purchasing dyes; at the same time, according to the method of foam application and The liquid-carrying rate of the foam can regulate the depth of the carried dye liquid into the fabric, giving the heavy fabric a double-sided style effect.” Wang Chaoxia, a professor at Jiangnan University, reported in the report “Research and Development and Industrialization of Key Technologies for Functional Textile Fabrics”, This article focuses on foam printing and dyeing and its development history, analyzes the advantages of foam printing, dyeing and finishing technology compared with conventional printing and dyeing technology, points out the problems of foam technology, and looks forward to the application prospects of foam technology in printing and dyeing.
Keqiao District is an industrial area mainly based on traditional textile printing and dyeing. In recent years, the printing and dyeing industry in the district is making steady progress towards high-quality roads and directions. The 2022 Advanced Textile Printing and Dyeing Innovation Forum was successfully held, providing guidance for many Keqiao textileprinting and dyeing enterprises. It will further promote the high-tech printing and dyeing industry and create a modern “international” for Keqiao. Textile Capital, Hangzhou-Shaoxing City” is poised to empower.
