Mat grass dyeing and drying process

Abstract

The invention discloses a mat grass dyeing and drying process, which comprises: (1) bundling harvested and washed mat grass by using a mat grass bundling drum to obtain a mat grass bundle, and draining; (2) vertically placing the mat grass bundle into a mat grass dyeing and drying integrated machine; (3) closing a closing door, adjusting a separation plate to an atomization dyeing position, starting a heating unit, heating a dyeing liquid to a temperature of 100-110 DEG C, starting an atomization unit, feeding the atomized dyeing liquid into the mat grass bundle from an output port, and carrying out atomization dyeing for 1-2 h; (4) after completing the atomization dyeing, adjusting the separation plate to a drying position, closing the heating unit and the atomization unit, starting a heat source after the temperature is reduced to less than 60 DEG C, and drying for 2-3 h at a temperature of 60-70 DEG C; and (5) after completing the drying, taking out the mat grass bundle, placing ina dry and ventilation place, and carrying out air cooling to a room temperature. According to the present invention, with the process, the dyeing steps are simplified, the dyeing and the drying can becontinuously completed in the same equipment, and the manpower cost and the time cost are substantially saved.

Description

technical field [0001] The invention belongs to the technical field of mat processing, and in particular relates to a dyeing and drying process of mat. Background technique [0002] Dyeing the mat grass can keep the mat grass natural green for a long period of time. The traditional process is to use clay slurry as the protective layer of the mat grass to prevent the green pigment of the mat grass from being damaged by ultraviolet rays during the drying process. thus keeping it green. This dyeing process plays a certain role in maintaining the color of mat grass, but there are problems such as short green retention time and uneven cyan color. At present, the commonly used dyeing method of mat grass is to select the mat grass and bundle it into 1-2 kg straw handles, put the straw handles vertically into the smoking room, ignite the sulfur to smoke the mat grass for 2-4 hours, and finish smoking. Finally, put the head of the grass stem into the dyeing pool (the composition of...

Problems solved by technology

[0005] In this dyeing method, the proportion of manual operation is still very large, and the equipment used is relatively primitive steamer and oven, so the whole dyeing process is relatively cumbersome.
