Reactive Dyes
Welcome to Polyventive, your top resource for high-quality reactive dyes. Reactive dyes are the ideal solution for adding vibrant, long-lasting color to textiles.
Chemistry of Reactive Dyes
So, how exactly do reactive dyes bond so effectively to textile fibers? It all comes down to their unique chemical structure. Reactive dyes contain chromophore groups that provide color. Bound to these chromophore groups are one or more reactive groups, such as vinylsulfone, chlorotriazine, trichloropyrimidine, and difluorochloropyrimidine.
When applied under alkaline conditions, these reactive groups form covalent bonds with hydroxyl or amino groups naturally present in cotton, wool, silk, and nylon polymer chains. This creates a highly stable coloration that is resistant to washing, light, perspiration, and other fading factors. By tweaking the type and concentration of reactive groups, our expert chemists can fine-tune the reactivity, shade depth, and technical properties of our dyes for optimal performance across applications.
Types of Reactive Dyes
With over 30,000 shades in our catalog, Polyventive offers the industry’s widest selection of reactive dye chemistries:
- Cold reactive dyes – Bond at temperatures under 40°C, ideal for cellulosic fibers like cotton.
- Hot reactive dyes Require higher temperatures of 60-90°C to react with fibers. They are mainly used for nylon and wool dye.
- Bifunctional dyes – Contain two different reactive groups for greater reactivity. Popular for cotton dyeing.
- Aminochlorotriazine dyes – The most common and economical reactive dye chemistry. Provides vivid colors across fabric blends and types.
- Dichlorotriazine dyes – Offer better wash fastness than aminochlorotriazine dyes. Used for kinds of cotton and rayon.
- Monofluorotriazine dyes – Provide excellent wash fastness and bright shades on all fibers.
This diverse catalog allows us to match the optimal reactive dye to your substrate, quality specifications, and end-use. Our chemists also regularly develop new reactive dye technologies to drive innovation in the textile coloration field.
Properties of Reactive Dyes
Reactive dyes check off all the boxes for an ideal textile dye. Key advantages include:
- Vibrant, consistent shades – Reactive dyes deliver eye-catching colors that hold up over time. No matter the batch, you can expect uniformity in hue and depth.
- Excellent wash fastness – Covalent bonding prevents fading or bleeding during washing. Colors stay true even after repeated laundering.
- High lightfastness – Colors retain brilliance even after prolonged exposure to light. You won’t have to worry about UV rays causing fading.
- Easy application – Reactive dyes streamline the dyeing process for textile mills. Their reactivity means less rinsing and wastewater too.
- Versatility – Suitable for dyeing cotton, wool, silk, nylon, and more. One reactive dye inventory meets needs across fabric types.
- Eco-friendly – Many reactive dyes meet stringent environmental standards. Their high wash and lightfastness also reduce re-dyeing needs.
These properties make reactive dyes the first choice over other dye types for critical textile applications like apparel, home furnishings, and upholstery. Our reactive dyes also provide batch-to-batch consistency for predictable coloring every time, enabling textile manufacturers to achieve accurate color standards across production runs.
Uses & Applications
With their winning combination of vibrant hues, excellent colorfastness, and ease of use, reactive dyes are the workhorse of the textile coloring industry. Major uses include:
- Cotton dyeing – Reactive dyes are the go-to for cotton fabrics like apparel, denim, towels, and bedding. They create vivid colors that hold up to repeated laundering.
- Wool and nylon dyeing – Hot reactive dyes bond effectively to wool and nylon without distorting these sensitive fibers. This makes them ideal for suits, coats, sweaters, carpets, and more.
- Silk dyeing: Mild cold–reactive dyes add bold, lasting colors to silk dresses, scarves, and ties.
- Digital textile printing – Reactive inks produce colorful designs on fabric that don’t fade or bleed, even after washing.
- Industrial coatings – Reactive dyes add weather-resistant hues to coatings on vehicles, pipes, or construction materials.
