Technological Innovation Trend Of Textile Printing

< p > > a href= "http://www.91se91.com/news/index_h.asp" > printing < /a > is a comprehensive process, involving a variety of advanced technology. With the continuous improvement of printing technology, new fibers, especially polyacetate fibers and reactive dyes and disperse dyes have come out one after another. Textile printing has entered the hall of science and technology from the workshop of technology, and has achieved unprecedented achievements.

< /p >

< p > traditional printing technology mainly includes roller printing, rotary screen printing and flat screen printing.

There are many traditional printing processes, such as "five ring relations" in the traditional printing industry, namely, "plate making network", "color mixing and sizing", "machine printing", "pattern design" and "post processing". These five production links are related, and any disjunction will directly affect the quality of printed cloth.

< /p >

< p > traditional printing water consumption links include fixation, soaping and water washing. These links are indispensable, and the discharge of sewage is inevitable.

With the advent of water crisis and increasingly serious environmental pollution, traditional printing technology will face more and more stringent restrictions.

Traditional printing technology has been greatly improved in environmental protection, but because of its own production technology characteristics, it is impossible to eradicate the pollution phenomenon fundamentally.

< /p >

< p > because printing production process is much, work is miscellaneous, many people use, processing technology is high, and production efficiency is low, so the whole printing production needs to change and upgrade the largest and most space.

< /p >
