Colorants that define future lifestyles are none other than reactive dyes. Although there are many other dyes like disperse dyes which have gained similar fame ground yet reactive dyes have bagged the priority. What makes reactive dyes pioneer of other dyes is its new level of reacting efficiency. They form covalent bond (aka strongest bond) with the substrate fibres resulting in everlasting colour freshness.
Before putting hands on being a textile manufacturer one must be thoroughly aware of physical forms and handling of reactive dyes. This is the balancing act for perfect production. Reactive dyes are manufactured in powdered form to ease the colouring process.
Following techniques are used to dissolve reactive dye powders.
Pasting: Here a paste is made with the steady addition of cold water. During paste formation, the mixture is kept at constant stirring.
Sprinkling: Here a steady stream of dye powder is sprinkled into the whirlpool formed by water stirring.
Possibilities indulged and ways to handle reactive dyes are:
Atmospheric conditions: The only yet biggest disadvantage of reactive dyes is that they are too friendly with water. They are prone to hydrolysis so to avoid inconvenience pack the package firmly after every use.
Possible Allergies: As reactive dyes are available in powdered form, consistent working in dust-full environment may lead to respiratory allergies. The best remedy to get rid of this is to install suitable dust-excluding respirators. Apart from these, ventilated enclosures can be installed for dye weighing and dissolving procedures.
Binding Temperature: The temperature at dye dissolving time plays a crucial role in imparting dye effects. The need of correct temperature should be examined precisely. Generally dye dissolving process includes cold water but reactive dye powders like Remazol (HOE) Vinyl Sulphone need boiling water to get dissolved. The correct temperature varies with the range of reactive dyes.
Apart from reactive dyes properties, knowledge of reactive dyes manufacturers is also a prime need. Leading reactive dyes manufacturers like https://www.sudeepind.com/reactive-dyes.html ensures their customers stay ahead in global market. Manufacturers that are open to the concept of new technology can deliver best. Reactive dyes have range of varieties and every dye has a purpose to fulfil. You can filter your purpose and then the type of reactive dye accordingly. Make sure the combination of demand and purchase go hand in hand.
