Chemical-free and environment-friendly washing method

The invention relates to the technical field of garment washing, in particular to a chemical-free and environment-friendly washing method. A laser printing treatment process is mainly used for replacing traditional hand wiping and coating printing processes, and defects of long process, large consumption and severe pollution of the traditional hand rubbing and coating printing processes are overcome; a pneumatic rubbing whitening treatment process is used to replace chemical material to realize traditional whitening processes such as enzyme washing, stone washing, rinsing and sand washing, a lot of water resources are saved, no sewage is produced, and wastewater emission is reduced; cloth is subjected to decoloration washing with an ozone degradation decoloration process, no chemical materials are used, and environmental pollution is reduced. 本发明涉及成衣洗水技术领域，尤其涉及种无化工环保洗水方法，主要通过使用激光镭射印花处理工艺替代了传统手擦、涂料印花工艺，避免了传统手擦、涂料印花工艺的流程长、消耗大、污染大的弊端；使用气擦磨白处理工艺替代了使用化工原料来实现磨白的酵素洗，石洗，漂洗，砂洗等传统磨白工艺，节省大量水资源，不产生污水，减少了废水排放；利用臭氧降解脱色工艺对布
