Problems solved by technology

[0003] After the non-woven fabric is formed, it needs to be dyed. The traditional dyeing method is to arrange the non-woven fabric in the dyeing pot for dyeing, cooling and washing in sequence. This traditional dyeing pot and dyeing process has the following defects: 1. Non-woven fabrics are directly piled up in the dyeing pot, resulting in uneven dyeing of the cloth; 2. The dyeing solution in the dyeing pot is prone to deposition or layering, resulting in uneven dyeing; 3. During the washing process, the cleaning water tends to overflow on the workshop floor On the one hand, it seriously affects the production environment of the workshop, and at the same time, the cleaning water is directly discharged, which is a serious waste; 4. The dyeing of non-woven fabrics is uneven and the color is not firm

Abstract

The invention relates to a non-woven cloth dyeing device which comprises a dyeing pot, wherein the top of the dyeing pot is opened; a liquid inlet and a liquid discharge hole are respectively formed in the upper part and the lower part of the side wall of the dyeing pot; a liquid bath heating layer is arranged on the side wall of the dyeing pot; a heating mechanism is arranged inside the liquid bath heating layer; a suspension mechanism for suspending cloth and a stirring mechanism are sequentially arranged from top to bottom inside the dyeing pot; a bent tube is arranged on one side of the dyeing pot; the lower end of the bent tube is communicated with the interior of the dyeing pot; the upper end of the bent tube is positioned above the top of the dyeing pot; a water pump is arranged onthe bent tube; a base is arranged at the bottom of the dyeing pot; the edge of the upper surface of the base concaves inwards to form a recycling groove; the recycling groove is communicated with a recycling tank through a pipeline. The invention further provides a non-woven cloth dyeing process. The dyeing process is simple. The non-woven cloth dyeing device has the beneficial effects that a dyeing liquid can be effectively prevented from deposition or layering, the dyeing liquid in the dyeing pot can be uniformly distributed, non-woven cloth can be dyed uniformly and brightly, and color fastness can be achieved.

Description

technical field [0001] The invention relates to the technical field of cloth dyeing, in particular to a non-woven fabric dyeing device and process. Background technique [0002] With the development of ultra-fine denier fibers and the characteristics of non-woven fabrics that do not need to remove the size, nylon-polyester non-woven fabrics are more and more used in automobile decoration and home furnishing industries, and the demand for colored non-woven fabrics is increasing , and the quality requirements are getting higher and higher. Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials with moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich colors, Low price, recyclable and so on. [0003] After the non-woven fabric is formed, it needs to be dyed. The traditional dyeing method is to arrange the no...
