Description

Technical Field

[0001] The utility model relates to the field of textile material detection, in particular to a polyester fiber impurity removal and processing device. Background Art

[0002] With the rapid development of the textile industry and the increasing requirements of consumers for textile quality and environmental protection, the performance of traditional polyester fibers has gradually failed to meet market demand, prompting the development and application of new polyester fiber materials. Compared with traditional polyester fibers, new polyester fibers have better physical and chemical properties and performance through improved polymerization processes, adjustment of molecular structures and introduction of functional groups. These improvements have significantly improved the skin-friendliness, breathability, and environmental protection of new polyester fibers, meeting the pursuit of high-quality life by modern consumers. For example, by introducing hydrophilic groups or adding soft segments, the moisture absorption, breathability, and softness of new polyester fibers have been greatly improved, showing significant advantages in comfort, durability, and environmental protection, greatly enhancing its application value in clothing, home textiles, and other fields. However, with the continuous innovation and application of new polyester fibers, their component detection and quality control technologies are also facing new challenges and requirements.

[0003] Fourier transform infrared spectroscopy (FTIR) plays an important role in textile component analysis due to its non-destructive, easy operation and fast analysis. However, in practical applications, impurities such as oil, dyes, and additive residues in textile samples will interfere with infrared spectra, especially in the detection of new polyester fibers. These impurities will not only affect the absorption characteristics of infrared spectra, but also may cause deviations in analysis results, thereby affecting the accuracy and reliability of component analysis. Therefore, before FTIR analysis, the fiber samples must be effectively pretreated to remove these impurities that may cause interference.

[0004] Traditional fiber pretreatment methods mostly rely on water washing, chemical solvent treatment, etc. Although they can remove impurities in the fiber to a certain extent, they often involve complex operation steps, long treatment processes, and the use of a large amount of organic solvents, which not only increase the detection cost, but also may cause environmental pollution. Therefore, there is an urgent need for an impurity removal device that can simplify the operation steps, improve the impurity removal efficiency, and be environmentally friendly.

[0029] Reference Figure 1As shown, the utility model provides a polyester fiber impurity removal processing device, comprising: an injection part 10, an extraction part 20, a separation part 30, a gas storage part 40 and a phase change processing part 50, the injection part 10 is used for automatic loading of polyester fibers, the phase change processing part 50 is used to convert carbon dioxide gas into supercritical carbon dioxide, the extraction part 20 is used to accommodate polyester fibers and supercritical carbon dioxide, the separation part 30 is used to recover supercritical carbon dioxide, and the gas storage part 40 is used to store carbon dioxide gas, wherein: the outlet of the injection part 10 is connected to the inlet of the extraction part 20, the extraction part 20 is connected to the separation part 30 through a first pipeline G1, the separation part 30 is connected to the gas storage part 40 through a second pipeline G2, the gas storage part 40 is connected to the phase change processing part 50 through a third pipeline G3, and the phase change processing part 50 is connected to the extraction part 20 through a fourth pipeline G4.

[0030] In the embodiment provided in the present application, the polyester fiber sample is automatically loaded into the extraction part 20 by the sampling part 10. After the supercritical carbon dioxide in the phase change treatment part 50 enters the extraction part 20 through the fourth pipe G4, it contacts with the polyester fiber sample. Under the action of the supercritical carbon dioxide, the impurities in the polyester fiber are dissolved and separated from the polyester fiber. The sampling part 10 is made of corrosion-resistant high-performance polymer material, which can prevent the polyester fiber sample from being contaminated during the sampling process. The inner wall of the extraction part 20 is made of tetrafluoroethylene material, which can enhance the compatibility with supercritical carbon dioxide and prevent chemical reactions from affecting the purity of the sample.

[0031] After the separation is completed, the impurities and supercritical carbon dioxide can enter the separation section 30 through the first pipeline G1. A U-shaped cold-trapped tube condensation module is provided in the separation section 30. The U-shaped cold-trapped tube condensation module can effectively reduce the loss of high-value components during the material separation process. In the separation section 30, the U-shaped cold-trapped tube condensation module can recycle the supercritical carbon dioxide to form carbon dioxide gas. The carbon dioxide gas can enter the gas storage section 40 through the second pipeline G2, and the impurities are retained in the separation section 30.

The stainless steel gas storage part 40 can improve the corrosion resistance of compressed gas and ensure safe storage, which is conducive to extending the service life of the equipment. The gas storage part 40 is mainly used to store carbon dioxide gas. When impurity removal treatment is required, the carbon dioxide gas in the gas storage part 40 can enter the phase change treatment part 50 through the third pipeline G3. The phase change treatment part 50 is provided with a heat exchange system. Under the action of the heat exchange system, the carbon dioxide gas can be converted into supercritical carbon dioxide to quickly achieve the phase change of the gas.

The sampling port 21 is arranged at the lower part of the extraction part 20 to facilitate taking out the polyester fibers after impurities are removed from the extraction part 20.

[0036] Reference Figure 3 As shown, a sealing component 11 is provided at the entrance of the sample inlet 10, and the sealing component 11 is used to seal the entrance of the sample inlet 10. After the polyester fiber sample to be impurity-removed enters the extraction part 20, the entrance of the sample inlet 10 is sealed by the sealing component 11, which can avoid the impurity removal process from causing pollution to the environment and improve the impurity removal efficiency.

[0037] The polyester fiber impurity removal processing device provided in the present application also includes a control unit 70, which can customize the operation program according to the type of polyester fiber and the characteristics of the impurities. The control unit 70 includes a programmable logic controller (PLC). Through the programmable logic controller, the user can customize the operation program according to different fiber types and impurity characteristics, realize full-automatic control, and improve the accuracy and reproducibility of the operation. The control unit 70 also includes a touch screen operation interface and a remote monitoring function, which can monitor and adjust the flow rate, temperature, pressure and processing time of supercritical carbon dioxide in real time to ensure the efficiency and consistency of impurity removal.
