Description

Environment-friendly non-woven fabric dip dyeing equipment and production process thereof Technical Field The invention relates to the technical field of non-woven fabric dip dyeing, in particular to environment-friendly non-woven fabric dip dyeing equipment and a production process thereof. Background The impregnated non-woven fabric is a non-woven material which is prepared from polyester fibers serving as a main raw material through the technological processes of net forming, reinforcing, impregnating, drying, winding and cutting and the like, and can be divided into two types of saturated impregnated non-woven fabric and foam impregnated non-woven fabric, and the existing non-woven fabric continuous dip dyeing equipment is produced by adopting a mode of matching a single long-shaped dip tank with continuous liquid supplementing. However, when the processing technology is actually applied, although the background continuously supplements liquid, after the newly injected high-concentration dye liquor enters the box body, the newly injected high-concentration dye liquor is difficult to be completely mixed with the original dye liquor in the box body in a very short time by virtue of natural diffusion or simple circulating stirring, when the cloth continuously passes through, the cloth is extremely easy to be stained with the dye liquor with uneven old and new mixing and with too high or too low local concentration, so that irregular instant color spots or transverse stripe color differences appear on the cloth surface, and although the prior art tries on various improvements such as an external blending tank, multi-point cloth liquor, partition isolation and the like, the contradiction cannot be fundamentally solved, and as long as the liquid supplementing and the soaking are carried out simultaneously in the same area, the cloth is inevitably stained with the dye liquor which is not uniformly mixed. Disclosure of Invention The invention discloses environment-friendly non-woven fabric dip-dyeing equipment and a production process thereof, and aims to solve the technical problem that cloth is stained with dye liquor which is not uniformly mixed due to simultaneous and regional performance of fluid infusion and dip-dyeing in the existing non-woven fabric dip-dyeing technology. In order to achieve the above purpose, the present invention adopts the following technical scheme: the environment-friendly non-woven fabric dip-dyeing equipment comprises a machine table, a feeding roller rotatably arranged at the top of the machine table and auxiliary rollers distributed below the feeding roller, wherein a dyeing box is arranged at the bottom of the machine table, and a regulating mechanism is arranged in the dyeing box; The regulating mechanism comprises a regulating plate which is slidingly distributed in the dyeing box, the regulating plate divides the inside of the dyeing box into a first chamber and a second chamber which have the same capacity, simultaneously, the inside of the first chamber and the inside of the second chamber are filled with the same equal parts of dip dyeing liquid, a non-woven fabric to be processed is contacted with the dip dyeing liquid in the first chamber and the inside of the second chamber only once, the first chamber and the second chamber are switched between a dip dyeing area and a to-be-fixed area, sliding grooves are symmetrically formed in two sides of the regulating plate, control rollers are slidingly installed in the inside of each pair of sliding grooves, a back plate is symmetrically installed on two sides of the inner wall of the dyeing box, and a connecting rod is rotationally connected between the back plate and the control rollers. A set of regulating mechanism is additionally arranged on the basis of the existing non-woven fabric dip dyeing technology and equipment, the whole dip dyeing tank is divided into a multi-dip dyeing area structure taking a first cavity and a second cavity as main bodies by using the regulating mechanism, the non-woven fabric is matched with a special distribution state of the non-woven fabric, the non-woven fabric is enabled to be alternately contacted with the first cavity and the second cavity, the first cavity and the second cavity are enabled to be alternately switched between a dip dyeing area and a to-be-positioned area, the fabric dip dyeing and the dye liquor supplementing are completely separated in time and space by means of dynamic isolation and time dislocation, the fabric is always contacted with the dye liquor which is fully mixed and is stable after standing for a long time, the possibility of non-uniform dye liquor contamination is fundamentally eradicated, the fabric continuously runs without pause and tension fluctuation despite the periodical movement of the regulating mechanism, the production efficiency is not affected, and compared with a pure multi-tank alternative scheme, the scheme only needs to be provided with a mo
