Dye

Sulfur black BN is a commonly used dye for black dyeing of cotton, linen, viscose fibers and their fabrics. Both the dye uptake and levelness are good. It can also be dyed with Vulcanized Black CLG to get jet black. It can also be used for dyeing vinylon. It is used for the dyeing of cotton and uv/cotton blended fabrics, as well as for the dyeing of hemp and viscose fibers.

Indigo dye is an organic compound with a distinctive blue color (see indigo). Historically, indigo was a natural dye extracted from plants, and this process was important economically because blue dyes were once rare. A large percentage of indigo dye produced today – several thousand tons each year – is synthetic. It is the blue often associated with blue jeans.

It is mainly used for dyeing and printing of fiber fabrics such as cotton, viscose, and hemp. It can also be used for dyeing silk and wool. It can also be used for dyeing paper and leather, and for the manufacture of lake pigments. In addition to dyeing scarlet and crimson (yellow light red) color alone, it is also used to match colors with yellow, orange, red, brown and other dyes. After dyeing, it is treated with urea-formaldehyde resin or treated with fixing agent Y. The color light-based benzene remains unchanged. If treated with fixing agent M, the color light becomes blue.

Direct Brilliant Yellow 4R is used for dyeing cotton and viscose fiber fabrics. It is red light yellow. It has good migration and level dyeing properties, high dye uptake, and has certain hiding power for dead cotton fibers and uneven viscose. For cotton fabrics, it is mostly used for the dyeing and printing of knitwear, flannel, and carpets, and is less used for cotton fabrics. High dye uptake rate of dyed rich fiber. It is also used for the dyeing of silk, wool, vinylon, nylon and blended fabrics. The color depth of silk, wool and cotton and viscose is similar, and the color of wool is slightly darker. Diacetate, polyester and acrylic are not stained. It can also be used for direct printing and ground color discharge of cotton, viscose and silk fabrics. In addition to being used alone, it is often used in combination with direct green B, direct dark green B, and direct acid-resistant scarlet 4BS. Used for the dyeing of cotton, linen, viscose and other fabrics, and for the dyeing of leather and pulp. It can dye silk and wool in a weak acid bath

Used for cellulose acetate, mordant cotton, but low fastness, bright color, can be used to make green or red, etc. It can also be used for dyeing leather, paper, linen and viscose. Alkaline could be used to color oil, fat, paint, etc. Lake can also be prepared for ink. It is mainly used for fluorescent staining of acid-resistant bacteria such as tuberculosis. After staining with the fluorescent dye AuramineO, the acid-fast bacteria will emit a bright orange color when inspected with a fluorescent microscope containing an ultraviolet light source. This method can be used for lower magnification microscopy, so acid-resistant bacteria can be found more quickly.

This product is used for dyeing paper, acrylic, silk, leather, feathers, and can be used for food and certain metal analysis reagents. It can be used as an adsorption indicator and biological dyeing agent. It can be used for dyeing paper, paint, acrylic and wood products. the study

1. Mainly used for dyeing pure polyester or acetate fiber. It can also be used for direct printing and transfer printing. Often with Disperse Red 3B; Disperse Yellow RL make up the three primary colors. Reactive dyes or direct dyes can dye polyester/viscose blended fabrics in the same bath. 2. Mainly used for coloring of polystyrene, ABS, rigid PVC resin and polyester fiber pulp and cosmetics.

Disperse Red 9, also called C.I. 60505 and 1-methylamino anthraquinone, is a red dye derived from anthraquinone. Disperse Red 9 is used in some older red and violet-red colored smoke formulations. It is used in the M18 colored smoke grenade and also often in dye packs. Its properties can be improved by coating the dye particles with an inert material, e.g. an epoxy resin.

1. Anti-infective (topical). Has been used as anthelmintic (Nematodes).
2. Antibacterial, anthelmintic
3. Used as indicator for copper salts.

Disperse Violet RL can be used for dyeing and printing of polyester, diacetate, triacetate, nylon and other fabrics. Good level dyeing and poor dyeing, mainly used for light colors. Dyeing polyester is bright red purple. Mainly used for high temperature and high pressure dyeing of polyester knitted fabrics or for adjusting shade.
