57741-47-6 Usage
Description
Tracid Red 2bs is a dark brown powder that exhibits a colorful red-blue light. It is soluble in water and becomes a deep red solution when dissolved in strong sulfuric acid. Tracid Red 2bs is primarily used in the dyeing and printing of nylon fabrics, particularly for polyamide fibers such as those found in carpets. However, it is not suitable for discharge printing.
Uses
Used in Textile Industry:
Tracid Red 2bs is used as a dye for nylon fabrics, particularly for polyamide fibers, due to its solubility and vibrant red-blue color. It is especially suitable for carpet dyeing, providing a long-lasting and attractive appearance to the carpets.
Used in Printing Industry:
Tracid Red 2bs is also used in the printing of nylon fabrics, offering a deep red color that is suitable for direct printing on polyamide materials. Its solubility in water and strong sulfuric acid makes it an ideal choice for creating visually appealing prints on nylon fabrics.
Standard (Polyamide) Properties:
Tracid Red 2bs exhibits the following properties when used on polyamide materials:
Light Fastness: ISO 6
This indicates that the color of Tracid Red 2bs remains relatively stable when exposed to light, making it suitable for long-term use in fabrics that will be exposed to sunlight or artificial lighting.
Soaping Fastness: 4-5
This suggests that the color of Tracid Red 2bs is resistant to fading when the fabric is washed with soap, ensuring that the color remains vibrant even after multiple washes.
Perspiration Fastness: 3-4
This indicates that Tracid Red 2bs is moderately resistant to fading when the fabric comes into contact with sweat, making it suitable for use in clothing that will be worn during physical activities.
Oxygen Bleaching: 5
This suggests that Tracid Red 2bs is highly resistant to fading when exposed to oxygen bleach, ensuring that the color remains vibrant even after bleaching treatments.
Fastness to Seawater: Fading and Stain
Tracid Red 2bs is not recommended for use in fabrics that will come into contact with seawater, as it may cause fading and staining.
Overall, Tracid Red 2bs is a versatile dye and printing agent for nylon fabrics, particularly for polyamide fibers, offering a vibrant red-blue color and good resistance to various factors such as light, soaping, and oxygen bleaching. However, it is not suitable for discharge printing and may not be ideal for fabrics that will come into contact with seawater.

Check Digit Verification of cas no
The CAS Registry Mumber 57741-47-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,7,4 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 57741-47:
(7*5)+(6*7)+(5*7)+(4*4)+(3*1)+(2*4)+(1*7)=146
146 % 10 = 6
So 57741-47-6 is a valid CAS Registry Number.
