Dye fastness of flame retardant fabric

Classification:
flame retardant fabric

Flame retardant fabricDye fastness is a quality requirement for dyed and printed fabrics, because dyed fabrics will be affected by light, sweat, and friction during wearing and storage FONT>, washing, ironing and other reasons may cause discoloration or discoloration, thus affecting the appearance of the fabric or clothing. The nature or degree of variation in dyeing state can be expressed by dye fastness. The dye fastness of fabric is related to fiber type, yarn structure, fabric structure, printing and dyeing method, dye type and external force. It can be divided into light fastness, washing or soaping fastness, rubbing fastness, perspiration fastness, ironing fastness, etc.

1. Sunlight fastness of flame-retardant work clothes Sunlight fastness refers to the degree of discoloration of colored fabrics under the action of sunlight. The test method can be either sunlight or a sun machine. The fading degree of the sample after exposure is compared with the standard color sample. It is level 8, level 8 is good, level 1 is poor. Fabrics with poor sun 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.

2. Washing fastness Washing or soaping fastness refers to the degree of color change of dyed fabrics after being washed with washing liquid. The gray graded sample card is usually used as the evaluation standard, that is, the color difference between the original sample and the sample after fading is used for evaluation. Washing fastness is divided into 5 levels, level 5 is good and level 1 is poor. Antibacterial deodorizing cloth
Fabrics with poor washing fastness should be dry cleaned. If wet cleaning is performed, extra attention should be paid to the washing conditions, such as the washing temperature should not be too high and the washing time should not be too long.

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

4. Perspiration fastness of anti-wrinkle and iron-free fabrics refers to the degree of color fading of dyed fabrics after being soaked in sweat. Since the composition of artificially prepared sweatis different, the perspiration fastness is generally assessed in combination with other color fastnesses in addition to being measured separately. The perspiration fastness is divided into levels from 1 to 5. The higher the value, the better.

5. Ironing fastness Ironing fastness refers to the degree of discoloration or fading of dyed fabrics when ironed. The degree of discoloration and fading is evaluated based on the staining of other fabrics by the iron at the same time. Ironing fastness is divided into levels 1 to 5, with level 5 being good and level 1 being poor. When testing the ironing fastness of different fabrics, should choose a good test iron temperature.

The dye fastness of normal fabrics is generally required to reach level 3~4 to meet the needs of wearing. However, the flame retardant fabrics we spin generally have It reaches level 4, and is non-toxic, odorless and non-irritating, making it suitable for people to wear.
