Usage

Description

Disperse Red 221 is a yellow light red powder that is used as a dye in various applications. It is known for its bright red color with a yellow light shade and is suitable for dyeing synthetic fibers such as polyester and cotton blends. It has good sublimation fastness and is compatible with other dyes, but its levelness is only fair.

Uses

Used in Textile Industry:
Disperse Red 221 is used as a dye for synthetic fibers such as polyester and cotton blends. It provides a bright red color with a yellow light shade and is suitable for dyeing and printing applications. The dyeing process requires an appropriate pH value of 4-6 and should not be used with alkali. The dye exhibits good ironing fastness, light fastness, perspiration fastness, and washing fastness, with ratings ranging from 4-6 according to the AATCC standard.
Used in Polyester/cotton Standard:
Disperse Red 221 is used as a dye for polyester/cotton blends, providing a bright red color with a yellow light shade. It has good sublimation fastness and is compatible with other dyes. The dyeing process requires an appropriate pH value of 4-6 and should not be used with alkali. The dye exhibits good ironing fastness, light fastness, perspiration fastness, and washing fastness, with ratings ranging from 4-6 according to the AATCC standard.
Used in Carrier Dyeing:
Disperse Red 221 can be used in carrier dyeing, but its performance is poor. The melt method should be used at a suitable temperature, not exceeding 220°C.
Used in Dyeing with Vinegar:
Disperse Red 221 can be used in dyeing with vinegar, but its performance is a bit poor when used with two vinegar fine and fair when used with three vinegar fiber.
Not suitable for Polyamide Fiber Dyeing:
Disperse Red 221 is not suitable for dyeing polyamide fibers, as its performance on this type of fiber is a bit poor.
Not suitable for Printing Discharge:
Disperse Red 221 cannot be used for printing discharge impressions.
