Fabric thermosetting intelligent control method and setting machine adopting same

Abstract

The invention discloses an intelligent control method for fabric heat setting and a setting machine adopting the method. The intelligent control method for fabric heat setting includes a step of heating the fabric impregnated with a process liquid in an oven of the setting machine and heating the fabric. The heat setting step of the fabric after the temperature rise, the method also includes the step of setting the running speed of the fabric according to the setting temperature Teff and the setting time S2 of the process requirements before the heating step, and during the heat setting step, according to the on-line monitoring setting The fabric temperature at the starting point of the zone, by adjusting the temperature in the oven in real time, makes the fabric temperature reach the required setting temperature Teff step of the process requirements after heating up; constant. The invention can accurately control the setting temperature of the fabric and the setting time at the setting temperature, improves the setting quality of the fabric and the drying efficiency of equipment, and saves energy.

Description

technical field [0001] The invention relates to a control method for fabric heat setting and a setting machine adopting the method, belonging to the technical field of textile dyeing and finishing technology and equipment. Background technique [0002] The setting machine is the equipment used for the setting of textile dyeing and finishing fabrics. After the fabric is soaked in the process liquid in the padding trough, it is squeezed by the padding rollers, and then enters the oven of the setting machine, and is heated up under the action of high-temperature hot air, dried and set. The heat setting of the fabric is to use the high-temperature hot air in the oven of the setting machine to eliminate the internal stress of the fabric fiber during the stretching process, so that the shape of the fabric is fixed and shaped. The fabric after setting has good dimensional stability, hand feeling, color and width. , strength and appearance. [0003] According to the principle of h...

AI Technical Summary

Problems solved by technology

[0004] In order to achieve the setting temperature and setting time required by the process, the existing setting machine usually adopts the single method of controlling the running speed of the fabric, that is, controlling the residence time of the fabric in the oven to meet the setting process temperature, but the actual setting effect is not ideal. In order to reach the setting temperature for heavy fabrics, reducing the fabric running speed can lengthen the residence time of the fabric in the oven, but reducing the fabric running speed will increase the amount of liquid carried by the fabric out of the rollers of the padding car, so it takes longer The drying time of the fabric reduces the running speed of the fabric, and does not necessarily reach the temperature required for setting within the heating and heating time; similarly, for fabrics with a small grammage, the running speed of the fabric is increased, and the speed of the fabric coming out of the rollers of the paddle car The amount of liquid will also be reduced accordingly, so it cannot be guaranteed that the temperature required for shaping can be reached within the heating and heating time.

That is to say, both of them have the uncertainty of setting time, and the uncertainty of setting time makes the fabric dimensional stability, dyeability poor, wrinkle resistance and hand feel are greatly affected, especially over-setting makes The fiber of the fabric is vitrified, the strength is greatly reduced, and the wearability is not up to the standard

In addition, the existing setting machine has high energy consumption and high production cost of the enterprise, which cannot meet the requirements of energy saving and environmental protection
