1. Color fastness:

The color of textiles is resistant to various physical, chemical and biochemical effects in the dyeing and finishing process or in the process of use and consumption.

2. Standard depth:

A series of recognized depth standards that define medium depth as 1/1 standard depth. Colors of the same standard depth are psychologically equivalent, so that color fastness can be compared on the same basis. At present, it has developed to a total of six standard depths of 2/1, 1/1, 1/3, 1/6, 1/12 and 1/25.

3. Dyeing depth:

Expressed as the percentage of dye weight to fiber weight, the dye concentration varies according to different colors. Generally, the dyeing depth is 1%, the dyeing depth of navy blue is 2%, and the dyeing depth of black is 4%.

4. Discoloration:

The change in shade, depth or brilliance of the color of a dyed fabric after a certain treatment, or the combined result of these changes.

5. Stain:

After a certain treatment, the color of the dyed fabric is transferred to the adjacent lining fabric, and the lining fabric is stained.

6. Gray sample card for assessing discoloration:

In the color fastness test, the standard gray sample card used to evaluate the degree of discoloration of the dyed object is generally called the discoloration sample card.

7. Gray sample card for evaluating staining:

In the color fastness test, the standard gray sample card used to evaluate the degree of staining of the dyed object to the lining fabric is generally called the staining sample card.

8. Color fastness rating:

According to the color fastness test, the degree of discoloration of dyed fabrics and the degree of staining to the backing fabrics, the color fastness properties of textiles are rated. In addition to the light fastness of eight (except AATCC standard light fastness), the rest are five-level system, the higher the level, the better the fastness.

9. Lining fabric:

In the color fastness test, in order to judge the degree of staining of dyed fabrics to other fibers, undyed white fabrics are treated together with dyed fabrics.
