Digital Inkjet Printing Enriches Printing Design Of Silk Products

Digital inkjet printing is a fast developing textile printing technology in recent years. In 1990s, with the application of CAD technology such as electronic color separation and color matching in textile dyeing and finishing industry, Japan, Holland and other countries successfully transplanted the technology of digital ink-jet printing for paper to fabrics. China's digital inkjet printing technology has developed rapidly in recent years. Hangzhou, Shandong, Beijing and other places have been widely applied in mulberry silk printing. Due to the reduction of the plate making process, the production cycle is greatly shortened, and the requirements of individuation, small batch and fast delivery can be maximally satisfied.

　　 Digital ink jet printing Digital technology is used to process images into computers and computers. Printing color separation system After editing, the inkjet printing system is controlled by special software, and the special ink is directly printed onto the silk. Digital printing technology does not require color separation, printing, plate making, network making, color matching and sizing. image processing After printing, production is not limited by quantity and length. Digital printing technology has greatly improved the clarity and color changes of ordinary printing. The resolution ranges from 360dpi to 144dpi, and the color can be more than ten million, which greatly enriches and meets the users' requirements for each fabric variety.

The shortcomings of digital jet printing and four color separation printing are the low output and high cost. How to make use of digital jet printer and color separation printing with conventional equipment, and ensure that the sample attachment rate of the four parts is an urgent problem. The project has been included in the national rolling plan for tackling key scientific and technological problems. The researchers, through the research of the common platform of digital jet and four color collaborative printing separation system, have combined the CAD/CAM collaborative color separation software, the synergy of key parameters and production processes, and the matching application of jet printing ink and four color printing special dyes, thus realizing the rapid proofing of digital jet printing machine and the processing and production of four scale color printing with large scale, low cost, less pollution and high quality.

Recently, the Jiangsu inspection and Quarantine Bureau industrial center and the Jiangsu Textile Engineering Society organized the implementation of the "textile use instruction (identification mark) inspection" proficiency test plan, which is the twenty-third time the center has jointly organized the proficiency testing activities with the Institute. The center's textile laboratory has thus become the only provider of proficiency testing in the field of textile chemistry and physical properties, filling the gap in the province.

According to the introduction, proficiency testing is the use of laboratory comparison to determine the laboratory's ability to detect and calibrate, as an effective means to evaluate the laboratory's technical capability, and has increasingly attracted the attention of testing institutions and management institutions at home and abroad. The ability validation provider is the organization responsible for all tasks in the establishment and operation of the proficiency testing plan. In terms of proficiency testing of textile physical properties, the province is in a long-term blank. The Jiangsu industrial and commercial inspection center of the inspection and Quarantine Bureau tackled technical difficulties with technological innovation and completed the expansion of the 7 projects that the PTP must have.

In the process of obtaining the qualification of the proficiency testing providers, the research level of the laboratory has also been significantly improved. The "entry and exit textile fiber detection technology and early warning system" has been awarded the three prize of the AQSIQ "science and Technology Promotion Award". The GC / MS has been patented for the rapid screening and testing methods of banned azo dyes in textiles, leather and dyestuffs, and the 3 industry standards such as "import and export textile functional items testing methods and breathability" have been approved. This will effectively improve the quality and safety level of import and export textiles, break down the technical barriers to international trade, and lay a good technical foundation for further expanding the foreign trade of textiles.
