Description

Drying equipment that weaving cloth was used Technical Field The invention relates to the technical field of cloth drying, in particular to drying equipment for textile cloth. Background In the production process, the textile cloth contains a large amount of water after the wet treatment procedures of dyeing, washing and the like, and the water must be removed through the drying procedure to reach the specified water content and create conditions for subsequent finishing. The drying is not only a process with huge energy consumption, but also the effect of the drying is directly related to the final quality of cloth, such as hand feeling, breadth stability, color fastness, surface evenness and the like. At present, cloth drying equipment widely adopted in industry is mainly a hot air tentering setting machine. The core working principle is that high-temperature air is generated by a heating device, hot air is forced to blow to the surface of continuously running cloth by a circulating fan, the cloth absorbs heat by means of convection heat exchange, moisture is evaporated, and moisture is taken away by airflow, so that drying is realized. The technology is mature and wide in application range, and is a mainstream choice in industry. However, the conventional hot air drying method has inherent disadvantages in that, first, hot air forms a relatively static "high temperature and high humidity boundary layer" on the surface of the cloth when it is blown to the cloth. This boundary layer severely impedes the diffusion of moisture inside the cloth to the outside air flow and the transfer of outside heat to the inside, resulting in reduced heat mass exchange efficiency. In order to meet the drying requirement, the hot air temperature is often required to be increased, the drying time is prolonged or the air quantity is increased, and the huge consumption of energy is directly caused. Secondly, uneven drying is easily caused due to uneven boundary layer distribution and structural difference of cloth, and local overdry or internal wet stagnation occur.
