A spray humidifier and chemical fiber spinning machine

Abstract

The invention discloses a spray humidifier, which is used to humidify the fiber belt inside the spinning shaft, and replaces the humidification of the whole spinning environment. The spray humidifier includes a box body, a water inlet valve, a water filter, and a tunnel humidification pipe. The water mist is sprayed out through the cooperation of various parts, and is brought into the spinning tunnel by the fibers moving downward, so that the fibers The belt fully and evenly absorbs water in the spinning tunnel, and can perform local humidification on the track of fiber movement, which not only solves the problems of energy waste, equipment damage, and personnel injury caused by humidification of the entire environment, but also solves the existing problems. The problem of low fiber dyeing rate and uneven dyeing. The local humidification of the invention has little influence on the humidity of the environment, does not cause damage to equipment and personnel, and can ensure the dyeing rate and dyeing effect, and improve the quality of products.

Description

technical field [0001] The application relates to the field of textile processing, in particular to a spray humidifier and a chemical fiber spinning machine. Background technique [0002] At present, when producing fibers such as nylon, chemical fiber spinning machines are generally used for production. [0003] In the production process, the fibers in production are generally humidified. This is because the insufficient moisture absorption of the fibers will affect the drawing and dyeing of the fibers during the spinning process. For example, take nylon as an example. Nylon is sensitive to moisture. Water molecules enter the amorphous area of ​​nylon and preferentially form a tight bond with it. The hydrogen bonds between them are further accumulated. Therefore, when the moisture absorption of nylon fiber is sufficient during spinning, the dyeing rate of the fiber is high and uniform; on the contrary, the dyeing rate is low and the color is uneven. [0004] The existing h...

AI Technical Summary

Problems solved by technology

[0004] The existing humidification technology is to humidify the entire spinning environment, including the spinning room and the winding room. The humidification space is more than 500 times the space occupied by the spinning tunnel. Not only the moisture absorption of the fiber is small, the energy consumption is high, and the The entire spinning environment is destroyed, causing equipment and electrical components to be damaged in a high-humidity environment, and workers who operate the equipment also feel uncomfortable in a high-humidity environment for a long time
