A few days ago, textile by atmospheric pressure plasma industry equipment development and its application technology development projects through the identification of experts. Experts say, to the project based on the further implementation of atmospheric pressure plasma equipment and textile technology industrialization, for textile printing and dyeing industry, green production and provide an effective way, the device is applied to cotton pretreatment process, thus saving energy and reducing emissions of around 30%, and reduced the production cost.
Textile by atmospheric pressure plasma industrial equipment applied as in recent years the domestic textile industry application of interdisciplinary frontier science technology to realize high efficiency and energy saving environmental protection production of cross-border cooperation sample. When the traditional textile industry and the emerging field of science and technology and the effective integration of the collision, we are in a higher broader horizon, had the foresight to realize effective energy-saving emission reduction industry in the future more possibilities of.
Plasma technology - to improve the dyeing properties of Lyocell fiber
In the textile field, atmospheric pressure plasma technology application universal attention at home and abroad. The technology can replace the conventional desizing scouring process, effectively improve the fiber dyeing and printing performance, improving the bond strength, improve the wool anti-felting performance, improve the fabric handle, removal of formaldehyde and allergic gas.
Low temperature plasma assisted dyeing technology of plasma technology in printing and dyeing industry in another application way. In the dyeing process of cashmere fiber, natural dyes on dyeing affinity is not big enough, not ideal, plus the cashmere is the cuticle layer block, the extra energy consuming dyeing. And due to the low temperature plasma treatment, will be part of the destruction of the chemical bond scales, the dye is easy to diffuse into the fiber, greatly improving the dyeing rate and dyeing rate, reduce the waste of residual dye, and is beneficial to environmental protection.
In addition, the low temperature plasma is also based on the wool surface is etched on the surface of the fiber, generating a large number of micro pits or cracks, increasing the contact area and a dye, but also increases the absorption of the incident light, to enhance color and improve the color fastness of the double effect, made up of natural dyes dyeing and color fastness is not ideal.
Ultraviolet technology - to reduce the use of chemicals and steam
Ultraviolet technology was originally applied in biological research, disinfection and other fields. Go up century 90 time later period, ultraviolet irradiation technology in printing and dyeing industry in the research and application of began to cause people to take seriously and be able to apply.
Ultraviolet light quantum possesses greater energy, so the UV radiation can be used in a variety of polymer fiber material surface modification, which gives the material moisture, antibacterial, deodorant, anti-static properties. Ultraviolet fiber effect only occurs in the surface tens to thousands of angstroms depth range, therefore does not affect the fiber on the basic physical properties. In addition, ultraviolet light can be used for improving the wettability of wool fiber and dyeing color yield, and can be used as alternative methods of traditional chlorination process for wool fabric printing pretreatment.
Ultraviolet solidification technology for treatment of UV technology in printing and finishing process is another practical application mode. Ultraviolet curable ink, can greatly reduce the solvent type ink volatile organic solvent pollution on the environment, the same mechanism can also be used in UV curing adhesives, ultraviolet curing coating, called" green industry new technology".
In recent years, as a new source of ultraviolet light, ultraviolet technology obtained the rapid development. Ultraviolet treatment of textile use water as a medium, without chemicals, steam, eliminate the drying process and wastewater treatment process, equipment investment is low cost, strong maneuverability, with energy-saving, efficient, environmental protection and other advantages.
Nanotechnology - raise energy utilization rate
Nanometer materials in energy saving and environmental protection has broad prospects. In the textile field, nanometer material is introduced into the can effectively improve the energy utilization rate, reduce harmful gas emissions, in recent years on nano catalyst, nano lubricant additives application development as an international textile technology field representative.
Nanometer materials in the textile industry has a lot of catalyst application examples, such as the nano zinc oxide, titanium dioxide nano two for water dye, hydrocarbon, phenols, surface active agent can effectively through photocatalytic reaction, by removing toxicity, decolorization, mineralization, eventually break down into carbon dioxide and water, thereby removing organic compounds to the environment pollution. Not only that, with two nm titanium dioxide on the heavy metal ions in the water have very strong reducing power, through photocatalysis can make 85% chromium six was restored, in the practical application has important significance to treatment of waste water containing chromium.
Nano lubricating oil additive can make industrial reducer of friction and abrasion, the decline of load current, so as to achieve energy-saving purposes. In 2007, Beijing Institute Of Fashion Technology School of materials science and Engineering" nanometer bionic self-organization lubricating oil additive and preparation method thereof" patent granted, the successful implementation of the domestic nanometer lubricating oil processing and preparation.
The Institute of University of Leeds and Britain European lubricating oil research center, the common mineral lubricating oil and adding nanometer additives for lubricating oils for reducer test, experiment, adding nanometer lubricating oil additive, current can be decreased by 6% ~ 12%, according to the average energy saving calculation 8%, per hour can save 3 of electricity, according to the working 8 hours every day, can save 24 electrical degrees, within a year of one such reducer can save 8760 of electricity.
Donghua University professor Xi Danli thinks, textile industry is a huge potential for energy saving industry, energy-saving emission reduction is essentially the industry technical level to reflect. Technology without borders, and no industry domain segmentation, reference and fusion is the development of human civilization. " Outside the box, can attack jade", how to expand the high and new technology application in textile industry field, will reduce cost, operation complete premise, to become the future industry to realize environmental protection and sustainable development of the mainstream direction.
