Description

Washing pumice for ceramic products

The invention relates to a ceramic product, in particular to a water washing pumice of an industrial washing machine for ceramic products for washing, such as textiles, denim garments and cloths.

Background technique

In recent years, environmental protection issues have received increasing attention from countries around the world, and various countries have formulated a series of policies and regulations to strengthen environmental protection. Specifically, strengthening environmental protection is mainly to reduce pollution caused by industrial waste discharge, and to pay attention to the recycling and development of industrial waste, especially to reduce environmental pollution caused by industrial waste emissions from sources, water pollution, etc. . Industrial pollution is diverse, such as the denim clothing that people often wear is relatively heavy, but in the 1990s, consumers put forward higher requirements for the softness, comfort and easy care of fabrics, so denim trimmers These requirements must be met. The constant improvement and rich fabrics, styling and color with the change of style while retaining the traditional style are also important reasons for its long-lasting popularity. Denim has been developed to retain its sturdy, wear-resistant, rugged fabric characteristics, and has been developed to eliminate the limitations of traditional sturdiness and become softer and more wear resistant. These light, thin, soft fabrics not only make denim more comfortable and natural, but also make it suitable for any season and more. In order to meet the needs of consumers, a variety of washing processes for textiles, clothing and fabrics have emerged.

The so-called "washing water processing" process is to put the finished clothes into an industrial water washing machine, add a certain amount of washing water pumice in the washing water, and use "medium impact" and "chemical reaction" through the medium and chemical agents. To produce textiles, clothing and fabrics after being washed Old, broken, faded, flowered, soft, distressed and fluffy. People wear denim garments, as well as textiles and fabrics after washing, which are more vivid in color, softer in texture and more comfortable to wear. In the prior art process of washing water for textiles, garments and fabrics, a large amount of natural pumice is required. Natural pumice is a stone formed under natural conditions after combustion in the volcanic crater, commonly known as "volcanic pumice stone". Not only its resources are limited, but also its shape and specific gravity are different. Its strength is low. In the process of washing and finishing, a large amount of sand and fine stones will be produced after being washed. These stains must be contaminated with clothing many times. Rinsing not only wastes water resources, but also frequently cleans the ditch and sewage sedimentation tanks, increasing the amount of sewage treatment and increasing production costs. This is still an environmental issue that needs to be solved in the water washing industry in today's environmental protection work for the remaining sand and fine stones containing chemicals.
