Spray humidifier and chemical fiber spinning machine

Abstract

The invention discloses a spray humidifier. The spray humidifier is used for humidifying a fiber belt inside a spinning channel instead of humidification on the whole spinning environment. The spray humidifier comprises a tank, a water inlet valve, a water filter and a channel humidification tube. Water mist is sprayed through cooperation of all components and is brought into the spinning channel via the fiber belt which moves downwards, so the fiber belt can fully and evenly absorb moisture in the spinning channel, and local humidification can be performed according to a fiber movement track. According to the spray humidifier, the problems that due to humidification on the whole environment, energy waste, equipment damage and staff injury are caused are solved, and meanwhile the problems that the dye uptake of existing fibers is low, and dyeing is uneven can be solved. Moreover, local humidification has little influence on the humidity of the environment, will not harm equipment or staff and can guarantee the dye uptake and the dyeing effect, thereby improving product quality.

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
