Clothing with diverse colors and styles meets people's needs for beauty and personalization. Meanwhile, it also brings certain difficulties to the quality control of clothing products. For instance, the color fastness of clothing products. So today, the Silicone Bra manufacturer will share with you how to test the color fastness of fabrics.

Generally, the color fastness of our fabrics is 3.5 grades, and that of fluorescent colors is 2-2.5 grades. Today, the Silicone Bra manufacturer mainly shares several test methods for color fastness: dry rubbing color fastness, wet rubbing color fastness, washing color fastness and water immersion color fastness.

Dry rubbing color fastness

Take a one-yuan coin and wrap it in a white cotton cloth. Rub the cloth clockwise 20 times to check the staining of the white cotton cloth

2. Wet rubbing color fastness

Soak all the test samples thoroughly. Take a one-yuan coin and wrap it in a white cotton cloth. Rub the soaked sample cloth clockwise 20 times to check the staining of the white cotton cloth

3. Washing color fastness

Take 50CM*50CM of the sample cloth to be tested, wash it three times in a household washing machine and let it dry. Compare the color of the sample cloth with the original wash water to observe the color fading situation

4. Water color fastness

Take about 20CM by 10CM of the sample cloth to be tested. Put 200ml of water at about 40℃ in A measuring cup and add a little laundry detergent. Soak the sample cloth of about 20CM by 10CM in the water cup for about 60 minutes. Take the sample cloth out and let it dry at room temperature. Compare the color of the original water-soaked sample cloth to observe the color fading situation
