Printing Of New Technologies?? No Paper Thermal Transfer Technology Introduction - Printing,

Q: Traditional Textiles Printing What way?

A: At present the textile fabric printing, there are two main methods: screen printing and heat Transfer printing .

Screen printing, it also includes offset printing and screen printing, its working principle is based on patterns of patterns, no part of the coating did not mesh to form a mesh pattern formed by the mesh pattern directly printed on the fabric paste leakage to complete the process of fabric printing. Followed with the pattern of the fabric after steaming, fixation, soaping, washing, are finished. This way, whether printing process or equipment are mature, production can reach 60 m / min. The main disadvantages of screen printing is the high water consumption (3 ~ 5m3/100 Namib), will generate a lot of water.

Heat transfer Pad Spent 60 years in the 20th century developed a new water-saving printing and dyeing technology, has been industrial application. Process is to dye Zuocheng ink, then printed out the heat transfer printing paper, then paste with cloth positive phase, at a certain temperature and pressure Pressing Tens of seconds, paper pattern was transferred to the fabric. Printed into the fabric so no fixing steaming, soaping and washing, so printing is not part of consumption of steam, coal, water, do not generate sewage. However, this process there are two major problems: India to use 1 m 1 mibu paper, paper consumption is not only occupancy costs, and indirect water consumption and water pollution caused; only printed polyester fabric, application area is restricted.

Q: What is the paperless transfer printing? Traditional printing methods are different?

A: heat transfer printing paper without first dye printing paste is made, then the way through the print pattern printed on a special substrate, and then compared with the fabric affixed through heat zone, heat zone in the substrate The pattern is transferred to and fixing the fabric, are finished printing. Among them, the substrate can be reused.

Thermal transfer printing process paperless main features include: solid color without steaming, soaping and washing, steam consumption in the non-printing areas, coal, water, does not produce water; no consumption of paper, does not produce a result of consumption of paper tape to the indirect water consumption and water pollution; printed pattern has a fine, clear, rich layers, natural, and can print photos and painting style similar to the product.

Q: paperless transfer printing of the strengths?

A: heat transfer printing process paperless outstanding advantage is the source of energy, in particular, is very precious water resources, consistent with national sustainable development strategy and.

Cost of printing and dyeing process produced nearly 50% of energy consumption, saving energy means lower production costs, but also the traditional printing process can produce difficult to produce high-grade products.

Q: varieties of cross-linking agent and what works?

A: Cotton and other natural fibers are hydrophilic, but can Heat Transfer Flowers disperse dyes are hydrophobic, difficult to combine the two, so natural fabrics can not directly heat transfer printing. One end to cross-linking agent combined with fiber, the other end can be combined with disperse dyes, disperse dyes and natural fibers that is a bridge between, thereby achieving natural fiber fabric heat transfer printing.

Crosslinking agents there are three varieties, one for cotton, polyester and silk.

Q: How do the technical feasibility of industrialization?

A: No paper heat transfer printing machine prototype trial is whether the process for industrial production of the core part, to anticipate all possible problems, problems must be resolved, in the machine to enlarge the newly discovered have to work out solutions to the problem, the only way to ensure the successful trial production of industrial machines.

Present, no paper heat transfer printing machine prototype debugging has been drawing to a close, the prototype proved successful trial of paperless technology industrialization as feasible.

Q: paperless transfer printing) glance " bone York crisis forced Nightmare?

A: heat transfer printing process paperless from the Beijing Institute of Clothing Research Group proposed that after nearly 10 years of research history, and in state "15" 863 Scheme, and after three years of research studies to obtain Paper-free aspects of breakthrough success for the paperless process has laid a good foundation for future development must have a more optimistic trend.
