The color difference of textile fabrics and its causes, the color difference of textile fabrics: the color of the dyed products is different, the shades are different, and the design samples do not match. According to the difference of chromatic aberration, it is divided into the same batch of color difference and the same color difference. The same batch of color difference means that in the same batch of products, there is a color difference between the product of a color number, between the box and the box, between the parts and the parts, between the package and the package, and between the pieces and the pieces. The same color difference refers to the color difference between the color difference, the front and back color difference, or the front and back sides in the same product. Color difference is one of the common rickets and multiple rickets in dyeing and finishing factories, which seriously affects the quality of dyed products.

Due to the different fiber composition of various types of fabrics, the types of dyes used in dyeing and the process equipment will also be different. There are different requirements and characteristics in dyeing processing, which causes the causes and performances of rickets. The color difference is varied in appearance, but the reasons are mainly as follows:

The dye is unevenly distributed on the fabric in advance. Before the dye is fixed on the fabric, if the distribution on the fabric is uneven, the color difference will be formed after the fixation. The main reasons for this phenomenon are: fabric factors, due to different fiber properties or pre-treatment, retreat, boiling, bleaching, silk is not enough to penetrate, so that the semi-products before the dyeing is not uniform, causing differences in the degree of dye absorption; Factors, due to mechanical structural reasons or improper operation, so that the liquid rate of the various parts of the fabric is inconsistent, resulting in chromatic aberration, uneven roll pressure, uneven dyeing, etc. will cause the fabric to absorb dye unevenness; pre-baking factors, When pre-baking after padding dyeing, the rate and degree of drying are inconsistent, causing different degrees of dye migration, resulting in uneven distribution of dye on the fabric.
