The Application Advantages of Microwave Fixation in Cotton Fabric Dyeing

摘要

Gradually along with the application of microwave technology, microwave components performance improves, and the cost drops sharply, so the technology, with the attitude of high and new technology, is widely used in dyeing industry. This paper from raw materials and equipment of microwave dying, introduced microwave dyeing process and the influence on cotton fabric dyeing. Tie-dye products are popular with most people because of its rich and colorful design and color, natural and unique shape of flower and breed design and color. This dye printing method can achieve tie-dye effect that other traditional tie-dyed techniques cannot achieve. Traditional techniques are only applicable in small batch and many varieties scale of production, and often with different fabric implementation means, such as sew, bundle, which leads to the result that dye solution cannot be evenly applied to different parts of the plant. Microwave dyeing is microwave heating technology. In addition to being applied to textile material drying operation, microwave technology also can be applied to dyeing and fixation treatment of printing and dyeing. Microwave for cotton fabric dyeing processing, dip the fabric in dye solution first, then put it in closed microwave regenerative chamber, based on the role of microwave technology on cotton dyed fabric, the dyes and auxiliaries molecules polarize or change again and again, after repeated friction heat between molecules, so as to achieve the purpose of rapid dyeing and color. Microwave dyeing technology heating is fast, and there is no heat loss and pollution of fabric. Microwave can guarantee the cotton goods inside and outside heat in a very short time with fabric dyeing uniformity, and good color fastness. Because microwave dyeing technology possesses the advantages of high efficiency and energy saving, and is easy to control, so, it is convenient for continuous production in textile industry.
