The Development Of Ecological Textile Technology Has Attracted Wide Attention.

The application of eco printing technology and ecological dyes, paints, thickeners and auxiliaries: Eco printing technology should first select dyes, coatings, thickeners and auxiliaries harmless to human body, prepare paste with environmental paste, use natural paste, and develop high thickening capacity, easy to recycle and purify environmental paste. This is the way to realize ecological printing process.

The application of pigment printing process is simple, the process is short, no water washing, no sewage or less sewage is in line with the principle of cleaner production.

The technology of digital inkjet printing is simple, without the need of network proofing, with high automation, rich colors, high resolution and no environmental pollution.

It will develop rapidly in the future.

Low, no need for pretreatment of paint ink.

Transfer printing is widely used for sublimation pfer printing of disperse dyes. Wet pfer printing of new ionic dyes such as thermal diffusion pfer printing and reactive dyes is being researched and developed.

For example, the use of pfer pfer printing.

It does not require baking and washing, no sewage discharge, but higher requirements for coatings and adhesives. Thermal diffusion pfer printing is one of the most promising imaging technologies at present.

From the perspective of international development, in the field of fiber materials, the research and development of new chemical fibers and the upgrading and utilization of natural fibers are still the focus of research and development of textile materials.

Fiber properties develop to the direction of high performance, the varieties of fiber develop to the direction of functionalization, fiber materials and fiber preparation develop to the ecological direction, and the size of fiber materials is developing to the direction of nanoscale.

All kinds of differentiated and functional fibers can improve and change the properties and functions of the original chemical fibers by using nano, differential, composite, ultrafine, copolymerization and grafting technologies, and apply them to the fields of dress, home textiles and industrial textiles.

The development of high performance fiber and polymer materials technology has become an important part of the development of chemical fiber in developed countries.

Aramid, polysulfonamide, carbon fiber, ultra high molecular weight polyethylene fiber and other technologies have accelerated development.

Japan's carbon fiber manufacturing company focuses on developing a carbon fiber with a tensile strength of 4000~5000MPa and a price equivalent to T300. The United States has launched a low cost carbon fiber development plan, developed a microwave plasma device, combined a typical independent and orderly carbonization and graphitization process, simplified the production process, and saved the cost of 2.2 kilograms per kilogram product.

High oriented materials and fiber thinning devices provide a new way for mass production of carbon nanofibers. In order to cope with a large number of oil resources that are not renewable in the short term and adapt to the needs of green environmental protection and sustainable development, research and development of new bio based fibers and recycling and recycling of resources have become a strategic plan of developed countries.

The United States, Japan and other countries have launched the renewable materials promotion plan, and have established research and development alliance, invested heavily in developing efficient cellulosic production technologies such as new solvent method and ionic liquid method. At the same time, the relevant enterprises have developed and recycled 30% of the carpet yarn and hollow pre spinning colored BCF fiber.

The use of bio molecular synthesis technology, genetic engineering, physical means and so on to cultivate new natural fibers, improve the performance of natural fibers, and upgrade the use of natural fibers has also become a hot topic of research and development.
