Disperse Yellow 198

Disperse Yellow 198 is synthesized from diethylene glycol, p-aminobenzoic acid and n-ethyl-3-cyano-4-methyl-6-hydroxy-2-pyridone. First, diethylene glycol is reacted with methanol to give methyl ether, then esterified with p-aminobenzoic acid, diazotized, and then coupled with n-ethyl-3-cyano-methyl-6-hydroxy-2-pyridone to give the product. After filtration, grinding and drying, the finished product is obtained.

Producing Method:


Disperse Yellow 198 is synthesized from diethylene glycol, p-aminobenzoic acid and n-ethyl-3-cyano-4-methyl-6-hydroxy-2-pyridone.

Application:It mainly used for polyester cotton printing with disperse dyes and reactive dyes. It is also suitable for polyester dyeing and printing and its blended fabrics.

Rubbing fastness


The rubbing fastness of the fabric is the same as the washing fastness, and it also includes two aspects:


One is dry rubbing fastness and the other is wet rubbing fastness.


Obtain the physical sample card of the dry rubbing fastness and wet rubbing fastness of the fabric through the detection of the fabric rubbing fastness testing instrument, and check the dry rubbing fastness and wet rubbing fastness of the textile by comparing the fabric color change sample card and the staining sample card. Very convenient.


Usually when testing the rubbing fastness of deep-colored textiles, the grade of dry rubbing fastness is generally about 1 grade higher than the grade of wet rubbing fastness.


Take direct dyeing of cotton fabric black as an example. Although it has been effectively fixed, the dry rubbing fastness and wet rubbing fastness are not very high, and sometimes it cannot meet customer requirements. In order to improve the rubbing fastness, reactive dyes, vat dyes and insoluble azo dyes are mostly used for dyeing. Strengthening dye selection, strengthening color fixing treatment and soaping are effective measures to improve the rubbing fastness of textiles.


In order to improve the wet rubbing fastness of deep-color cellulose fiber products, special additives that can improve the wet rubbing fastness of textiles can be selected, and the wet rubbing fastness of the product can be significantly improved by padding the special additive when the finished product is finalized. Spend.


For dark-colored chemical fiber filament products, the wet rubbing fastness of the product can also be improved by adding a small amount of fluorine-containing water repellent when the finished product is shaped.


When acid dyes are used to dye polyamide fibers with deep colors, the wet rubbing fastness of nylon fabrics with deep colors can be significantly improved by using a special fixing agent for nylon.


For sanded dark-colored products, when testing their wet rubbing fastness, the level of wet rubbing fastness may be reduced because the shedding of short fibers on the fabric surface of sanded products is more obvious than other products.
