Description
Technical Field
The invention relates to the field of laser cleaning, in particular to a cleaning device for cleaning fabrics by laser and a working method thereof.
Background
The mainstream fiber textile fabric cleaning methods at present are mainly divided into two types. Depending on the solvent used, wet (water is used as solvent and a surfactant-based detergent is added for cleaning purposes) and dry (tetrachloroethylene, 1, 2-trifluoro-1, 2, 2-trichloroethane, glycol ether, etc. are used for cleaning purposes) respectively. The wet cleaning consumes a large amount of water, and simultaneously, a large amount of detergent is used to pollute the water body. The dry cleaning method is suitable for fabrics which are not easy to wash and fade. However, the use of large amounts of organic solvents presents a significant health risk. It is known that tetrachloroethylene is a carcinogen and neurotoxin, and has strong destructive power to environment. In 2017, 10, 27, the list of carcinogens published by the international cancer research institute of the world health organization is preliminarily collated for reference, and dry cleaning (occupational exposure) is performed on the list of 2B carcinogens.
Currently, mainstream laser cleaning technologies can be classified into the following three categories: laser ablation cleaning: laser is directly irradiated on the object to be removed, and the object to be removed is gasified or decomposed and removed based on transient high temperature generated by the laser; liquid film assisted laser cleaning: coating a layer of liquid film (water, alcohol or other liquid) on the surface of an object to be cleaned in advance, irradiating by laser, enabling the liquid film to explode after absorbing laser energy, enabling the liquid boiling by explosion to move at high speed, and removing surface dirt; laser shock wave type cleaning: the laser is emitted in the direction parallel to the surface of the base material, the laser beam is focused on the accessory of the particles to be removed, the laser ionizes air at the focusing point to generate shock waves, and the shock waves rapidly expand towards the periphery to remove the particles. The method is mainly suitable for removing microparticles on a plane. The method has very strict process requirements, and not only can ensure air ionization, but also can control the proper distance between the laser and the substrate to ensure that the impact force acting on the particles is large enough.
At present, laser cleaning is only applied to removing organic matters, oxide layers, microparticles and other pollutants on the surfaces of hard materials such as metal, semiconductor, glass and the like, and because the cleaning of fabrics is greatly different from the current laser cleaning technology, the heat resistance and the stability to photon irradiation of fabric fibers are far lower than those of materials such as metal, semiconductor, glass and the like, the fabrics are not convenient to adopt a laser cleaning mode in the traditional thought.
