The main factors that affect the color cast of polyester webbing are as follows.
(1) Numerous differences in the quality of raw materials and semi-finished products, textile structure, warp density, warping force and thickness will cause color cast. Due to the difference in productivity between textile machines and dyeing machines, blank belts produced by different textile machines are colored on the same dyeing machine, and even ribbons of different batches are also colored on the same dyeing machine. In order to minimize the influence of the difference in the quality of the Burlap Ribbon Bulk on the color cast, it is required that weaving and coloring must be coordinated and integrated into the production plan. In addition, the inventory management of blank strips should try to ensure the "first in, first out method".

(2) Equipment management The baking oven should be repaired and maintained regularly to ensure the normal operation of the heating equipment, normal heating and temperature control. In the specific production process, the air duct in the box must be unobstructed and the filter screen must be cleaned. Dyeing equipment is very important for the adjustment of the support force of the blank belt. Before entering the dyeing tank, the supporting force of the blank belt should be basically the same, so as to ensure the consistency of the liquid loading rate, and then ensure the consistency of the color tone. It is also important to manipulate the dyeing equipment to increase the tension on the webbing. Since the Satin Ribbon Wholesale dyeing equipment generally uses frequency conversion control to adjust the strength of the entire dyeing equipment, it is necessary to ensure that the frequency conversion control signal of each process point is normal, and the failed components must be repaired in time.
(3) The choice of dye matching has a great influence on the color cast on both sides of the webbing. When using different recipes to produce the same color, the color cast between the front and back of the Satin Ribbon Wholesale will be quite different. In general, choose disperse dyes with the same or similar color fastness and type (S, SE, E type) for matching, and the coloring effect will be better. In addition, the auxiliary use of modifiers such as anti-swimming agents, penetrating agents and leveling agents also has a certain effect on the control of color cast, but it must be used reasonably.
