Six Main Type Textile Fastness

1.Light fastness

Light fastness refers to the degree to which a colored fabric is discolored by the action of sunlight. The test method can be sunlit or sunlit, and the degree of fading of the sample after sunlit is compared with the standard color sample, which is divided into 8 grades, 8 grades are the best, 1 grades are the worst. Fabrics with poor light fastness should not be exposed to the sun for a long time, and should be dried in a ventilated place.

2. Rubbing fastness

Friction fastness refers to the degree of color loss of dyed fabric after friction, which can be divided into dry friction and wet friction. The friction fastness is evaluated by the degree of white cloth staining, which is divided into 5 levels (1~5). The larger the value, the better the friction fastness. The service life of fabrics with poor rubbing fastness is limited.

3. Washing fastness

Washing or soaping fastness refers to the degree of color change of dyed fabric after washing with washing liquid. Usually the gray grading sample card is used as the evaluation standard, that is, the color difference between the original and the sample after fading is used to judge. Washing fastness is divided into 5 levels, 5 is the best, 1 is the worst. Fabrics with poor washing fastness should be dry cleaned, if wet washing, you need to pay more attention to the washing conditions, such as washing temperature can not be too high, the time can not be too long.

4. Ironing fastness

Ironing fastness refers to the degree of discoloration or fading of dyed fabric during ironing. The degree of discoloration and fading is assessed by the color of other fabrics with the iron at the same time. Ironing fastness is divided into 1 to 5 grades, 5 is the best, 1 is the worst. When testing the ironing fastness of different fabrics, the temperature of the test iron should be selected.

5. Fastness to perspiration

Perspiration fastness refers to the degree of discoloration of dyed fabric after immersion in sweat. Perspiration fastness Because the composition of artificially prepared sweat is not the same, it is generally measured separately and combined with other color fastness. Perspiration fastness is divided into 1 to 5 levels, the greater the value, the better.

6. Sublimation fastness

Sublimation fastness refers to the degree of sublimation that occurs in dyed fabric during storage. Sublimation fastness The degree of discoloration, fading and staining of white cloth after dry hot pressing treatment is evaluated by grey grading sample card. There are 5 grades, 1 is the worst, 5 is the best. The dyeing fastness of normal fabrics is generally required to reach 3 to 4 levels in order to meet the needs of wearing.
