The introduction of color fastness

This article aims to introduce the types of fabric color fastness and precautions so that you can buy the fabric that suits you.

1, Rubbing fastness: Rubbing fastness refers to the degree of fading of dyed fabrics after rubbing, which can be dry rubbing and wet rubbing. The rubbing fastness is evaluated based on the degree of white cloth staining, and it is divided into 5 levels. The larger the value, the better the rubbing fastness.

2, Light fastness: Light fastness refers to the degree of discoloration of colored fabrics under the action of sunlight. The test method is to compare the fading degree of the sample after simulating sunlight with the standard color sample, and it is divided into 8 grades, 8 is the best result, and 1 is the worst. Fabrics with poor light fastness should not be exposed to the sun for a long time, and should be placed in a ventilated place to dry in the shade.

3, Sublimation fastness: refers to the degree of sublimation of dyed fabrics in storage. The dye fastness of normal fabrics is generally required to reach 3-4 grades to meet the needs of wearing.

4, Washing fastness: Washing or soaping fastness refers to the degree of color change of dyed fabric after washing with washing liquid. Usually, the gray graded sample card is used as the evaluation standard, that is, the color difference between the original sample and the faded sample is used for judgment. The washing fastness is divided into 5 grades, grade 5 is the best and grade 1 is the worst. The fabrics with poor washing fastness should be dry-cleaned. If they are wet-washed, the washing conditions should be paid extra attention, such as the washing temperature should not be too high and the washing time should not be too long.

5, Perspiration fastness: Perspiration fastness refers to the degree of color fading of the dyed fabric after a small amount of perspiration.

6, Ironing fastness: refers to the degree of discoloration or fading of dyed fabrics during ironing.
