A Briefing on the Properties and Applications of Basic Dyes

Basic dyes belong to the class of synthetic dyes and are from the family of aniline dyes. These dyes are called so because they are salts of organic bases. They are also referred to as cationic dyes because in solution these dyes molecules ionize, causing its colored components to turn into an action of positively charged radical. Generally, these dyes are considered very easy-to-use and they can be used in several of printing and dyeing tasks. They feature excellent tinctorial strength and great brilliance, both of which are not at all excelled by any other category of dyes.

Properties:

• The characteristics that make these dyes special are the intensity and brilliance of their colours.
• They are readily soluble in mentholated spirit and alcohol
• Many of these dyes are hardly soluble in water.
• The major property of these dyes is that they will fuse with tannic acid to form an insoluble compound, provided mineral acid is not present.
• These colorants have poor fastness to light and differ in regard to washing fastness from poor to moderate.
• The wet fastness of these dyes on protein fibres can also be enhanced by means of back tanning. This includes treating the dyed material with tannic acid to form the insoluble compound, thereby alleviating the tendency to migrate.
• Materials like cotton are regarded as inadequate substrate for these dyes because they do not possess the entailed planar structures to absorb dyes.
• Most of these dyes are chlorides by chemical combination and they have positively charged colouring agent (or chromospheres).
• Majority of these dyes have vivid colours with varied range of brilliance. Besides, they may exhibit fluorescent properties and may occur in different colours.
• Special cationic dyes are also available for dyeing acrylic fibres.
• These dyes are utilized for woolen materials when particularly vibrant shades are required that cannot be obtained with acid dyes.
  

Applications:
Applications on wool, paper, wood, feather, straw-braided articles, leather and cotton is recommended. Selected members of this category can also be utilized for printing or dyeing on polyacrylonitrile fibre and acetate fibre.

Furthermore, the freebases of these dyes can be utilized as solvent dyes. Pigments precipitated by the combination of these dyes with phosphotungstomolybdic acid, display high fastness to light. They are extensively utilized in the manufacturing of stationery items like stamp-pad inks, carbon paper and ball-pen. In addition, these dyes can be employed as colouring elements in distemper when precipitated in China clay.

Cationic dyes are economical as compared to the other dyes. These dyes are extensively known to produce some of the best synthetic dyes utilized for commercial purposes. These dyes are a popular choice for their usage in hand painting on acrylic fibre because they are bright in colour and have a wash-fast property, when utilized on acrylic. They are also utilized for permanent dying of containers, floors, sinks, counters and wide array of other materials.

Basic dye is reliable and has strong colorants having numerous commercial applications. To know more about basic dyes and its properties, log on to www.royceintl.com. Royce offers a widespread range of performance based Specialty Chemicals.
