According to China Drying Network News, “Chongqing Chemical Industry has only 2,445 patents, accounting for only 0.8% of the national total, and invention patents account for nearly 5 percentage points less than the national level.†September 25, 2009, from the Chongqing Municipal Intellectual Property Office. According to the news, the Bureau will implement a patent product doubling plan and strive to achieve a total of more than 1,000 patents for chemical industry in Chongqing by 2015. The relevant person in charge of the Chongqing Municipal Intellectual Property Office analyzed that at present, Chongqing’s patents in the chemical industry are mainly based on basic chemical raw materials, accounting for nearly 50% of the total, and the amount of patents granted in the fields of synthetic materials and chemical fertilizers is only 11%. The patent quality needs to be improved. At the same time, the patented density of production value in the chemical industry in Chongqing was 0.31 pieces/billion yuan, which was lower than the national average of 0.37 pieces/billion yuan. To this end, the Chongqing Municipal Intellectual Property Office will support enterprises in conducting comparative analysis of patented technologies, guide enterprises to avoid patent risks, support enterprises in tracking patent trends, and help Chongqing chemical industry to improve the market competitiveness of products. Piezo Jacquard is a type of electronic jacquard system used in warp knitting machines. It is a modern technology that uses piezoelectric sensors to control the warp yarns in the knitting process.
Overall, Piezo Jacquard is a valuable technology for warp knitting machines, allowing for greater creativity and precision in the production of high-quality knitted fabrics.

The piezoelectric sensors are placed on the needle bed of the machine and are used to detect the position of the warp yarns. This information is then sent to a computer, which controls the needle selection and knitting process.
The Piezo Jacquard system allows for greater flexibility and precision in the knitting process, as it can quickly and accurately adjust the needle selection to create complex patterns and designs. It also reduces the need for manual adjustments, saving time and improving overall efficiency.
