The quality of Fabric thread ribbon, machine management and dyeing formulation also have important influence on the control of dyeing color difference. In the process of thermosol dyeing of polyester Fabric thread ribbon, the consistency of the quality of green ribbon should be controlled systematically, the maintenance and maintenance of the machine table should be done in time, and the dyes and auxiliaries should be used reasonably in order to obtain good dyeing effect.
The factors such as roll pressure, uniformity of fixing temperature in baking oven, infrared pre-baking temperature, moisture content and mass concentration of anti-swimming agent all affect the color difference of continuous thermal dyeing of polyester Fabric thread ribbon.
Generally, the roll pressure is 0.2 MPa, the difference between the left, middle and right of the oven temperature is not more than 2 C, the infrared pre-baking temperature is 100 C, and the mass concentration of anti-swimming agent is not more than 15 g/L. The green strip should be fully dried before and after pretreatment to effectively control the dyeing color difference of the ribbon.

On the colour fastness of Fabric thread ribbons
The color fastness of Fabric thread ribbon is one of the important quality indexes of textiles.
The so-called color fastness refers to the degree to which the color of dyed textiles remains firm under the physical and chemical effects.
That is to say, the color fastness of dyed textiles affected by the outside world is called color fastness.
The colour fastness is expressed by the change of colour and lustre of the test sample and the grading of the staining degree of the white cloth.
Among all kinds of color fastness items of Fabric thread ribbon, the most commonly used color fastness at present are rubbing fastness, perspiration fastness, washing fastness, light fastness, water-soaking fastness, brushing fastness, climate fastness and so on. In real life, the final use of products is the main basis for deciding which items to assess.
Among them, sweat resistance, dry friction resistance and water-resistant color fastness are the items required by the basic safety technical specifications of textiles.
All dyed textiles should be assessed.
In addition, the saliva color fastness of textile products for infants and young children should also be tested.
Visual evaluation method is generally used to evaluate the color fastness of Fabric thread ribbons, that is, grey sample card is used as standard sample, under certain lighting and environmental conditions, the gray card and sample are compared with human eyes to determine the original sample discoloration and staining series of white cloth.
Grey cards (discoloration and staining, respectively) have five fastness grades, namely 5, 4, 3, 2 and 1. Level 5 is the best and level 1 is the worst. In each of the two levels, we add half grade, that is 45, 34, 23, 12, so our daily gray card is 5 grade 9, and the color fastness evaluation result is one of 9 grades.
If a certain color fastness of the ribbon product does not reach the standard level, then the ribbon product is not qualified.
Following are the standards for weaving Fabric thread belts that must be met:
1. The washing fastness of Fabric thread tape is above 3.5 grade, passing ISO105-C01:1989 test standard.
2. Fabric thread tape rubbing fastness above 3.5 grade, passed ISO105-X12:1993 test standard
3. The fastness to sunlight of Fabric thread tape is above grade 4. It has passed the ISO105-B02:1994 test standard.
3. On the light source of Fabric thread tape painting
Fabric thread ribbon textiles thread have to go through many processes in the production process.
In this process, due to the errors caused by various reasons such as raw materials, production technology, operation, etc., the fabrics in different batches, or even the same batch, will vary in color.
Fabric thread color difference size, if the color light source is different, the color environment, the color time is different, the evaluation of color difference is also different.
Therefore, in order to accurately evaluate the color difference and ensure the consistency of color results, in the visual evaluation of color, we must select the light source designated by the merchant in the standard color matching light box to avoid the visual difference caused by the non-standard light source or different light sources.
