Description

  The present invention belongs to the technical field of manufacturing pressure vessels and textile dyeing / finishing apparatuses, and particularly relates to a universal prototype for anhydrous dyeing of supercritical fluids.

  Prototyping plays an important role in the production and production of textiles, and is a prerequisite for obtaining a base composition for production and processing, particularly for color production of textiles. Therefore, the development of an efficient, reliable and suitable prototype system is very important for obtaining the base composition required for production quickly and accurately.

However, in recent years, as the standards and requirements for ecological environment protection have increased and the enforcement of environmental protection policies has increased, traditional textile printing production has encountered unprecedented challenges and difficulties. Therefore, by researching and developing anhydrous dyeing and finishing processing technologies using fluids such as supercritical CO ₂ as a processing medium, we will completely eliminate problems such as ecological environment protection caused by traditional textile printing processing. It is very important economically, environmentally and socially for sustainable development of traditional textile printing industry and ecological environment protection. Therefore, research and development of a prototype system for anhydrous dyeing of supercritical fluid is very important for the spread, application and industrialization of anhydrous dyeing and finishing technology.

Currently, supercritical CO ₂ anhydrous dyeing technology for textiles has made significant progress. In related departments at home and abroad, equipment systems that can be used for dyeing and processing fabric prototypes have been developed. Among them, there are many vertical beams, horizontal beams, and skein dyeing and rope dyeing using two axes.

In the integrated dye dyeing pot, the dye can be dissolved in the same pot, and the dyeing process of the fabric can be completed under the conditions that the pressure of the supercritical fluid is 10 to 45 MPa and the temperature is 100 to 180 ° C. Patent Document 2 (“Method and Apparatus for Treating Fabric Substrates Using Supercritical Fluids”) describes a vertical beam high pressure dyeing kettle and system for dyeing fabrics that become bobbins or endless fabrics. ing. By controlling the processing temperature and time, it is possible to carry out dyeing under conditions of constant pressure, for example 280 bar and high processing temperature.

  Patent document 3 (“textile supercritical fluid processing apparatus”) by the present applicant includes a gas storage bottle, an air flow outlet, a pressure pump, a preheater, a high pressure dyeing kettle, a heat exchanger, a separator, a dye dissolving kettle, A horizontal warp beam mode multifunction processing apparatus comprising a bidirectional circulation pump and a control valve and having a fluid circulation system capable of achieving processing such as uniform dyeing of fabric under constant system pressure and temperature conditions It is disclosed. In addition, in Patent Document 4 (“Apparatus and method for dyeing fibers using supercritical carbon dioxide fluid”) by the present applicant, a special seamless warp beam composed of an inner layer and an outer layer is adopted, and a cylindrical mesh-like shape is adopted. A seamless woven fabric is sleeved on the outermost layer of the outer fabric, and supercritical carbon dioxide fluid pressure is 10 MPa to 30 MPa, temperature is 90 ° C. to 140 ° C., using fluid circulation and fluid static dyeing, It has been published to uniformly dye post-dyed fabrics in a critical carbon dioxide fluid.

The supercritical carbon dioxide fluid medium can be operated by circulating the rope-like fabric sequentially in conjunction with the action and rationally controlling process parameters such as the circulation flow rate of the dyeing fluid, the circulation speed of the fabric, the dyeing temperature and pressure. It has been made public to realize the post-dyeing of the inner rope-like fabric.
