Definitions

  • the present application is directed to a waterless processing of textile materials using supercritical fluid.
  • this technology does not apply water, the dyes and the carbon dioxide can be recycled and the dyeing procedure does not require the use of chemical additives.
  • the supercritical carbon dioxide is a superb non-polar solvent, which can dissolve oil grease, oily material and impurities on some functional materials or textiles. Therefore, besides the dyeing procedure, such technology can be applied during the pre-processing of textiles for extracting oil grease and impurities. For example, at the time of cleansing and rinsing, functional materials, such as silicon or fluorine-type of synthetic material with water-proof function, can be added in the dyeing procedure. So the dyeing and functional processing procedure under waterless processing can be performed simultaneously, and the total processing time can be reduced.
  • the technical problem that the present application seeks to solve is to provide a method of waterless processing of textile materials using supercritical fluid. It is a completely waterless and environmental-friendly textile processing procedure, which can complete the pre-processing of cleansing (such as the procedure of removing grease and impurities), functional processing, independent processing or continuous processing of the dyeing procedure and post-processing and cleansing of washing off unfixed dyes in textile materials as such procedures.
  • the present application provides the use of supercritical liquid to perform highly efficient pre-processing, dyeing and post-processing of textile materials as an integration technology, which can clean and dye at the same time and highly raise the efficiency level.
  • the cleansing procedure can be proceeded as a continuous direct cleansing procedure, which is different from the traditional indirect cleansing in batches. It can greatly raise the cleansing efficiency and reduce the cleansing time.
  • the present application is suitable for performing pre-processing of cleansing, dyeing, post-processing of washing off unfixed dyes or adding functional materials to artificial or natural textile materials. It can supersede traditional processing procedure of the pre-processing of scouring, dyeing and post-processing and adding functional materials.
  • a method of waterless processing of textile materials using supercritical fluid includes a pre-processing procedure of cleansing a textile material using a supercritical fluid, before a process of dyeing the textile material using the supercritical fluid.
  • the method may further include a post-processing procedure of washing off unfixed dyes on the textile material using the supercritical fluid, after the process of dyeing the textile material using the supercritical fluid.
  • the method may further include a post-processing procedure of adding a functional material to the textile material using the supercritical fluid, after the process of dyeing the textile material using the supercritical fluid.
  • the pre-processing procedure of cleansing may include treating gaseous carbon dioxide by a supercritical process so that the gaseous carbon dioxide reaches a supercritical state; passing the supercritical carbon dioxide through a high-pressure cauldron with the textile material provided therein, thereby rinsing the textile material and removing grease therefrom; and depressurizing and separating the grease from the carbon dioxide, and collecting the carbon dioxide in gaseous state for re-use.
  • the post-processing procedure of washing off unfixed dyes may include treating gaseous carbon dioxide by a supercritical process so that the gaseous carbon dioxide reaches a supercritical state; passing the supercritical carbon dioxide through a high-pressure cauldron with the textile material provided therein, thereby washing the textile material and removing the unfixed dyes therefrom; and depressurizing and separating the unfixed dyes from the carbon dioxide, and collecting the carbon dioxide in gaseous state for re-use.
  • the method may further include the step of adding an organic solvent in the high-pressure cauldron in advance in the pre-processing procedure of cleansing and the post-processing procedure of washing off unfixed dyes, wherein the added organic solvent is in an amount of 0.1-10% by weight of the textile material.
  • the post-processing procedure of adding the functional material may include treating gaseous carbon dioxide by a supercritical process so that the gaseous carbon dioxide reaches a supercritical state; passing the supercritical carbon dioxide into a functional material can with the functional material provided therein so that the functional material is dissolved in the supercritical carbon dioxide; passing the supercritical carbon dioxide with the dissolved functional material into a high-pressure cauldron with the textile material provided therein, thereby performing sedimentation of the functional material in the textile material; and depressurizing and separating the functional material from the carbon dioxide, and collecting the carbon dioxide in gaseous state for re-use.
  • the supercritical carbon dioxide with the dissolved functional material in the high-pressure cauldron may be led back to an entry port of the functional material can through a control valve, a flow meter and a high-pressure cycling pump, thereby repeatedly performing sedimentation of the functional material until the functional material is fully absorbed by the textile material.
  • the method may further include the step of adding a functional material into a dyeing can containing a dyeing material, passing supercritical carbon dioxide into the dyeing can so that it dissolves the dyeing material and the functional material; and passing the supercritical carbon dioxide with the dissolved dyeing material and functional material into a high-pressure cauldron with the textile material provided therein, thereby performing sedimentation of the dyeing material and the functional material in the textile material.
  • the functional material can be a compound comprising fluorine or silicon.
  • the present application provides a method of waterless processing of textile materials using supercritical fluid, and also includes a procedure of independently adding the functional materials after dyeing. Firstly, a pre-processing procedure of cleansing can be performed on the textile materials using supercritical fluid. Secondly, the supercritical fluid can be used for dyeing of and adding functional materials to the textile materials. Lastly, a post-processing procedure of washing off unfixed dyes can be performed on the textile materials using supercritical fluid. The detailed work flow is illustrated in Figure 3 .
  • the present embodiment provides a method of processing textile materials using supercritical fluid. Before using the supercritical fluid to dye the textile materials, supercritical fluid can be used in a pre-processing procedure of cleansing the textile materials. A specific procedure is described as follows:
  • Embodiment 2 (example of dyeing and adding of functional material):
  • the present embodiment provides a method of processing and dyeing textile materials using supercritical fluid, including the post-processing procedure of washing off unfixed dyes after dyeing.
  • Liquid carbon dioxide is stored in a storage can with a temperature at moderate level and pressure at about 5Mpa.
  • the carbon dioxide enters a cooler and temperature is maintained at about 0 ⁇ 10°C (preferably at 5°C). At this stage, the carbon dioxide is in a fully liquid form.
  • the carbon dioxide is pressurized to a suitable pressure by a high-pressure pump.
  • the pressure can be maintained at about 10Mpa to reach a supercritical fluid condition.
  • the temperature can then be raised to about 50 ⁇ 100°C by a heat exchanger.
  • the carbon dioxide then enters into a high-pressure cauldron and rinses the textile materials provided therein.
  • the carbon dioxide dissolving the unfixed dyes can be depressurized to about 5Mpa through a depressurizing valve.
  • the absorbed heat can be replenished by a heat exchanger, causing the temperature to be maintained at about 40°C.
  • the carbon dioxide may then enter into a carbon dioxide separating can.
  • the carbon dioxide is in gaseous form.
  • the dissolved grease and unfixed dyes can be released in liquid form or solid form and kept at the bottom of the carbon dioxide separating can.
  • the gaseous carbon dioxide can be released from an upper portion of the carbon dioxide separating can, and may then flow into a cooler, causing the temperature to be dropped and maintained to about 0 ⁇ 10°C (preferably at 5°C). Only at this time the carbon dioxide can be converted into liquid form, and can be recycled through the carbon dioxide storage can for a second round of cleansing. This forms a continuous cleansing procedure using supercritical fluid.
