Importance of Basic and Acid Dyes

• Dyes or colors are very much relevant in
  the textile dyes manufacturing industry. Amongst
  several classifications,
• the classification based on pH value term them
  as acid dyes and basic dyes.
• Lets understand their characteristics and
  importance.

Basic dyes

• These dyes are cationic which means they have a
  positive charge. Since they show the typical
  properties of a base, they are known as basic
  dyes.
• Since the basic dyes show a positive charge, they
  get stuck to every fabric. It is the reason they
  stain everything they touch during the
  processing.
•  
• Even the plastic and silicone sealants also get
  the color.
•  
• Due to the positive charge, the dye attracts to
  proteins and nucleic acid in the body. Hence,
  they are used as a biological stain. However, it
  is hazardous to the health also.

Usage and importance of basic dyes

• The basic dyes include all synthetic textile
  dyes. They are historically significant, and
  because of their ability to stain and bind
  different parts of human cell, the basic dyes are
  used in the medicines.
• The basic dyes can color any fabric, natural or
  synthetic. However, with the natural fibers, they
  show poor light fastness. It restricts the use of
  basic dyes in versatile applications.
• The introduction of acrylic fibers made them
  relevant. On the acrylic fibers, they show a
  reasonably good life fastness.
• It is quite apparent that the use of basic dyes
  is not recommended for hand dying because of
  their affinity to proteins. The long-term use can
  cause serious health hazards.

Usage and importance of basic dyes

• Acid dyes are based on salts of phenolic,
  sulfuric or carboxylic acids. The dyes are
  soluble in water and show an affinity towards all
  types of fibers. The pH value of them lies
  between two and five.
• Since they are highly water soluble, the light
  fastness of acid dye is better than basic dye.
  They are appropriate for all natural and
  synthetic fibers.
• Acid dyes are negatively charged, and they are
  divided into two groups acid-leveling and
  acid-milling. The chemical structure of these
  dyes is made from large aromatic molecules with a
  sulphonyl or amino group that makes them soluble
  in water.

Properties of acid dyes

• The dyes form a large anion when they dissolve in
  water. They are ideal for dying silk, wool,
  polyamide, and acrylics.
• Their pH value ranges from extreme acidic to
  neutral.  Acid dyes are not suitable for dying
  cotton fabric as they dont show any affinity to
  cotton cellulose.
