The HTHP dual flow fabric dyeing machine is not sensitive to the wrinkles of the semi-products. After dyeing, the fabric has uniform color, fullness and good hand feeling. Especially after the chemical fiber and the blended fabric are processed by the dyeing machine, the fabric is soft and elastic, and has good texture. The hair feel and imitation cotton effect.
In the production, it is necessary to determine the actual capacity of the high-temperature and high-pressure double-flow fabric dyeing machine according to the thickness, width and narrowness of the fabric. For fabrics of the same width, the thinner and thinner the smaller the fabric. The fabric in the dyeing chamber is pulled by a winch and then enters the nozzle. The nozzle is an annular outlet, and the dyeing liquid is ejected from the gap of the nozzle. The dyeing liquid is sprayed on the rope fabric by the pressure of the nozzle, and the speed of the fabric which is folded in the dyeing chamber due to the accumulation in the dyeing chamber is determined by the speed of the winch. And nozzle pressure.
In the temperature region where the fabric absorbs the dye, increasing the number of cycles of the fabric, that is, increasing the running speed of the fabric, is advantageous for leveling of the fabric. When the amount of liquid is constant, by increasing the flow rate of the dye solution, the number of cycles of the dye solution can be increased, the temperature in the dyeing machine and the uniformity of dye distribution can be increased, and the number of times of contact between the dye and the fabric can be increased, and the dyeing time can be shortened.
The bath ratio of the HTHP dual flow fabric dyeing machine not only affects the color of the fabric, but also affects the normal operation of the fabric in the dyeing machine. Therefore, the determination of the bath ratio should be minimized without affecting the operation of the fabric and ensuring the quality of the dye.
