Usage

Description

Disperse Orange 44 is a red light orange colored, orange powder that is commonly used as a dye for polyester and their blended fabrics. It is also suitable for dyeing vinegar fiber.

Uses

Used in Textile Industry:
Disperse Orange 44 is used as a dye for polyester and their blended fabrics due to its ability to provide a vibrant and long-lasting color. It is also used in the dyeing of vinegar fiber.
Standard:
Disperse Orange 44 meets the AATCC standard, which is a widely recognized standard for textile testing and certification.
Ironing Fastness:
Disperse Orange 44 has a rating of 5-6 on the AATCC scale, indicating that it has excellent resistance to fading and staining when exposed to heat and pressure during the ironing process.
Light Fastness:
Disperse Orange 44 has a rating of 4-5 on the AATCC scale, which means it has good resistance to fading when exposed to sunlight or artificial light.
Perspiration Fastness:
Disperse Orange 44 has a rating of 5 on the AATCC scale, indicating that it has excellent resistance to staining when exposed to sweat.
Washing Fastness:
Disperse Orange 44 has a rating of 4-5 on the AATCC scale, which means it has good resistance to fading and staining when exposed to the washing process.

Preparing method of environment-friendly azo dispersing dyestuff

The invention provides a preparing method of environment-friendly azo dispersing dyestuff. The preparing method comprises a diazotization reaction and a coupling reaction, wherein auxiliaries of ferric trichloride, hydrogen peroxide and sodium hypobromite are added in the coupling reaction system. 23 kinds of harmful aromatic amine, benzene containing chlorine, methylbenzene containing chlorine and phenol containing chlorine contained in the dyestuff prepared according to the method are greatly lowered, in this way, the dyestuff conducts dyeing, and 23 kinds of harmful aromatic amine, benzenecontaining chlorine, methylbenzene containing chlorine and phenol containing chlorine on obtained fabric meet limit requirements in an Oeko-Tex Standard100.

Stable diazonium salts of weakly basic amines—Convenient reagents for synthesis of disperse azo dyes

A new synthetic strategy for industrially important deep-shade disperse azo dyes was presented in this study. The key procedure is to prepare stable solid diazonium salts of weakly basic amines in the absence of concentrated sulfuric acid. Diazotization by tert-butyl nitrite in ethyl acetate was allowed to proceed in the presence of equivalent 1,5-naphthalenedisulfonic acid as stabilizer of diazonium salts and donor of hydrogen ion for the reaction. The separated solid diazonium salts exhibited good thermal stability. The corresponding disperse azo dyes were subsequently synthesized through the azo-coupling of the prepared solid diazonium salts with a range of aromatic tertiary amines. The azo dyes were produced in short reaction time, excellent yields, mild reaction conditions, simple experimental procedure and low energy consumption.
