Abstract

The invention discloses a digital active wet process transfer printing method of a cellulose fabric. The digital active wet process transfer printing method of the cellulose fabric is performed by the five steps: manufacturing a special transfer printing medium; jet-printing a pattern; pre-processing a fabric; performing transfer printing; and performing post-finishing of the fabric. According to wet process transfer printing, by spraying a pre-processing liquid, the fabric is dyed and fixed in color in a clinical water content stat when fibers are subjected to maximum swelling without taking urea as a moisture absorbent, and the fabric is not padded and pasted, so that the washing difficulty is reduced, and sewage discharge is reduced. The method disclosed by the invention not only has the advantages of clear and smooth digital inkjet printing pattern and rich layers of picture, but also has the characteristics of efficient production of conventional transfer printing and environmental protection and energy conservation, and further has the characteristics that the active print is bright in color, excellent in hand feel, good in color fastness and healthy and comfortable.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a digital active wet cloth for cellulose fabrics. [0002] transfer printing method. Background technique [0003] Environmental protection has become a bottleneck restricting the development of my country's printing and dyeing industry. Research and development of low-emission, low-pollution printing and dyeing technology has become a top priority for my country's printing and dyeing industry; on the other hand, with the development of social culture and the improvement of people's aesthetic taste, suitable for individual There is a huge room for development in the printing technology of high-quality and small-batch production. At the same time, the rapid development of domestic e-commerce has also built a good platform for the production and sales of personalized customized textiles. [0004] There are generally three types of research in the printing and dyeing in...
