What is dyeing & printing?

Dyeing and printing are processes employed in the conversion of raw textile fibres into finished goods that add much to the appearance of textile fabrics.

What is the difference between dye and pigment?

Colorants are either dyes or pigments. Technically speaking, the difference is that dyes are soluble in the host material—typically water—while pigments are not. Another difference is that dyes do not scatter light and look transparent. On the other hand, pigments do scatter light and, thus, they are opaque (see Fig.

What are the importance of dyeing and printing?

Dyeing and printing is known to be an ancient technique of enhancing the look of a fabric. As dyeing and printing is considered a beautiful art of surface ornamentation, it is predominantly taught in most fashion designing institutes.

What are the five stages of dyeing and printing?

Stages of Dyeing

• Stock and Top Dyeing.
• Yarn Dyeing. 2.1 Skein Dyeing. 2.2 Package Dyeing. 2.3 Beam Dyeing.
• Piece Dyeing. 3.1 Typically Piece Dyed Fabrics. 3.2 Jet Dyeing. 3.3 Jig Dyeing. 3.4 Pad Dyeing. 3.5 Beam Dyeing.
• Garment Dyeing.

What are the process of dyeing?

Dyeing Process: Dyeing the fabric means transferring the color on the textile material (yarn or final fabric.) Basically, the dyeing process is all about absorption and diffusion. Absorption is transferring of dyes from the aqueous solution onto the fabric surface and diffusion is dyes getting diffused into the fibers.

Is dyeing correct?

Dying is most used as the present participle of the verb to die, i.e. to cease to live. Dyeing is the present participle of the verb to dye, i.e. to turn a material from one color to another.

Is a pigment a dye?

The main difference between dye and pigment is that dye molecules are very small whereas pigments are much larger. Therefore, dyes easily dissolve in water and many solvents while pigments do not dissolve in water. Dye and pigment are two types of compounds which can impart a color to a material.

What is water based pigment?

Water-based pigment dispersions are used instead of dyes in applications which require opacity, light stability and/or thermal stability. Pigments are particles and are generally more opaque than dyes, although some of our dispersions can be manufactured to be transparent.

What is the importance of dyeing?

The countless advantages of dyeing include not only being cost effective but one easy way of transforming your fabrics to look new. It is also a great way to renew the fabrics you currently have and enjoy each one year after year. Dyeing fabric has to do with the process of textile colouring using pigments.

What is the main purpose of dyeing?

The primary objective of dyeing is to apply uniform color to the substrate (fiber, yarn, or fabric) with required color fastness. Tie-dye and printing are the methods where the color is applied in a localized manner.

What are the steps of dyeing?

What is the Process of dyeing Fabric?

• Singeing and Desizing: They are the first two steps of pre-treatment respectively.
• Sourcing: This is done to remove the impurities over the textile material.
• Bleaching: In this step, the natural color of the raw materials reduced.

What is running shade?

Running shade is more specifically meter to meter variation of shade in fabric. So, basically when dyes cannot migrate properly in the whole fabric thus exhaustion of dyes in fabric becomes uneven which leads to running shade or uneven dyeing.

What’s the difference between printing and dyeing fabric?

According to the design, printing has localized application of dyes or pigments on the fabric. In this process dyes or pigments are applied on fabric with the help of thickener.

How are dyes used in the printing process?

Printing is another part of the dyeing process. According to the design, printing has localized application of dyes or pigments on the fabric. In this process dyes or pigments are applied on fabric with the help of thickener. Generally steaming is used in the printed fabric for fixation therefore a strong bond is formed between dyes and fibers.

What is the difference between dying and dyeing?

Dyeing is one of the major procedures in the textile manufacturing process. Dying is the process where textile materials are become changed physically or chemically and looks colorful. In this process fabric, yarn and fibers are dyed.

What’s the difference between dye paste and printing paste?

The density of dye solution is less than the density of printing paste. 8. In printing, the density of printing paste is higher than dye solution density. 9. Huge amount of water is required for dyeing.
