Low-temperature negative pressure drying method and device for textile materials and textiles

Abstract

The invention discloses a low-temperature negative pressure drying method and a low-temperature negative pressure drying device for textile materials and textiles. The device comprises a microwave source, a temperature sensor, a resonant cavity, an air-cooled or water-cooled device, a vacuum sensor, an air release valve, a humidity sensor, an air extraction valve, an air extraction pipeline, a vacuum pump, a vacuum pump motor, a stirrer, a panel, a controller, a shielding sealing door, a shell, an indicating lamp, a switch, a scattered article drying box and a cheese drying bracket; and the scattered textile materials or textiles are put into the scattered article drying box, or cheeses are stacked on the cheese drying bracket and then put into the resonant cavity, and the dried articles are heated and dried under the low-temperature negative pressure working condition. Relatively long bottleneck at the uniform velocity drying stage when single microwave is used for drying can be effectively overcome, over drying is avoided, and the whole drying process is quick and energy-saving; and the method and the device can particularly meet the drying requirements of special animal fibers, artificial fibers, synthetic fibers and like and the products thereof with special temperature requirements.

Description

Technical field: [0001] The present invention relates to the technical field of combination of small and medium power microwave sources, to the technical field of vacuum negative pressure drying, and to the technical field of low-temperature drying of textile materials and textiles by using a combined microwave device combined with a vacuum negative pressure device. A method and device for low-temperature negative-pressure drying of textiles. Background technique: [0002] In the textile, dyeing and finishing industry, drying of natural fibers (including plant fibers, animal fibers, mineral fibers), chemical fibers, synthetic fibers and other textile materials, as well as various types of yarns and textiles made of textile materials It is an extremely important processing link. Since drying heat energy consumption accounts for a relatively large proportion of the total heat energy consumption in the entire textile production process, rational selection of drying methods and...

Problems solved by technology

Although the latent heat of vaporization of water will increase as the boiling point decreases, the difference between the two still further reduces the energy required for the entire drying process and improves the drying efficiency.
