The reasons for the color difference of textile fabrics are summarized

Color difference is a problem of all textile nonwovens. Whether it is textile yarn fabric or polypropylene non-woven fabric, there will be more or less poor coloration. Next, let's look at the reasons for the chromatic aberration and how the fabric with large chromatic aberration is caused. If the distribution on each part of the fabric is not uniform, the dye is distributed unevenly on the fabric before the dye is fixed on the fabric. After fixing, chromatic aberration must be formed. Due to the inconsistency of the drying rate and degree, the dyes will migrate to different degrees and the dyes will be unevenly distributed on the fabric. Uneven roller pressure, uneven dye dissolution, etc. will cause the fabric to absorb dye unevenly; the pre-baking factor, when pre-baking after the padding liquor, due to mechanical structural reasons or improper operation, the fabric will carry liquid in various parts The rate is inconsistent, resulting in color difference. The uneven permeability of the semi-products before dyeing causes the difference in the degree of dye absorption, due to the different fiber properties or the pre-treatment degrading, boiling, bleaching, and the silk is not uniform enough. There are different requirements and characteristics in the dyeing process, which make the causes and performance of defects different. The chromatic aberration is varied in appearance. Due to the different fiber composition of various fabrics, the types of dyes and process equipment used in dyeing will also be different. Chromatic aberration is one of the common defects and multiple defects in dyeing and finishing plants, which seriously affects the quality of dyed products. The color difference of the same horse refers to the chromatic aberration of the edge, the chromatic aberration of the front and rear, or the chromatic aberration of the front and back sides of the same product. The color difference of the same batch refers to the color difference between the box and the box, the piece and the piece, the bag and the bag, and the horse and the horse in the product of one color number in the same batch of products. The color and luster obtained after dyeing the product show different shades, and the shade is different, which does not match the design sample. According to the difference of color difference, it is divided into same batch color difference and same color difference. The above is a detailed summary of the reasons for the color difference in textile fabrics. If you have any questions, you can directly contact the relevant personnel of Fujian Nonwovens Co., Ltd.
