There are significant differences between active flame retardant fabrics and Shilin dye (i.e. vat dye) flame retardant fabrics in multiple aspects. The following is a detailed comparison of these two fr fabrics:

1、 Dye characteristics and dyeing process

Reactive dye flame retardant fabric

Dye characteristics: also known as reactive dyes. The molecule contains chemically active functional groups that can react with fibers such as cotton and wool in aqueous solution to form covalent dyes. Has high wash fastness. Reactive dyes have bright colors, complete chromatography, and good washing and friction resistance.

Dyeing process: The dyeing process of flame-retardant fabrics with reactive dyes is relatively simple, usually using methods such as immersion dyeing or pad dyeing. During the dyeing process, it is necessary to control appropriate conditions such as temperature, pH value, and electrolyte concentration to ensure sufficient reaction and uniform dyeing between the dye and the fiber.

Shilin dye flame retardant fabric

Dye characteristics: Shilin dye, also known as reducing dye, is a type of dye that can dye fibers after being reduced to a latent color under alkaline conditions, and then oxidized to restore its original insolubility. Shilin dye has excellent light resistance, water washing resistance, and friction resistance, and the various fastness of dyed fabrics is good.

Dyeing process: The dyeing process of Shilin dye flame retardant fabrics is relatively complex, usually including steps such as reduction, dyeing, and oxidation. During the dyeing process, it is necessary to control appropriate conditions such as temperature, pH value, and reducing agent to ensure sufficient reduction and uniform dyeing of the dye. In addition, the dyeing equipment of Shilin dye is relatively complex, requiring professional dyeing equipment and operating techniques.

2、 Fabric Performance and Application

Reactive dye flame retardant fabric

Fabric performance: Reactive dye flame-retardant fabrics have the characteristics of bright color, complete chromatography, excellent washing and friction resistance. Meanwhile, due to the formation of covalent bonds between reactive dyes and fibers, the color fastness of dyed fabrics is relatively high.

Application: Reactive dye flame retardant fabrics are widely used in various fabrics that require flame retardant properties, such as firefighting clothing, industrial protective clothing, etc. In addition, due to its bright color and complete color spectrum, it is also suitable for making flame retardant clothing in multiple industries.

Shilin dye flame retardant fabric

Fabric performance: Shilin dye flame retardant fabric has excellent light resistance, water washing resistance, and friction resistance, and the various fastness of dyed fabrics is good. In addition, Shilin dye flame retardant fabric also has good hand feel and breathability.

Application: Shilin dye flame retardant fabrics are also widely used in various textiles that require flame retardant properties, such as work clothes, protective clothing, etc. Due to its excellent color fastness and hand feel, it is also suitable for making various clothing that require high strength and aesthetic performance.

3、 Price and Cost

Reactive dye flame-retardant fabrics: Due to the relatively simple dyeing process and low cost of reactive dyes, the price of reactive dye flame-retardant fabrics is usually relatively low.

Shilin dye flame retardant fabric: Due to the relatively complex dyeing process and high cost of Shilin dye, the price is usually relatively high.

In summary, there are significant differences between reactive dye flame-retardant fabrics and Shilin dye flame-retardant fabrics in terms of dye characteristics, dyeing processes, fabric properties and applications, as well as price and cost. The choice of fabric depends on the specific application scenario and performance requirements.
