Recommended Process

1. Reactive printing recipe:

Water: X g

Urea:  5-10g

Resist salt:   1g

Sodium hexametaphosphate: 0.5 - 1g

Sodium bicarbonate: 1 - 3g

  • What is textile thickener?

    Thickeners used in textile printing are high molecular weight viscous compounds gave a sticky paste with water, which impart stickiness and plasticity to the printing paste. These thickeners facilitate to preserve the design outlines without spreading even under high pressure.

  • Why thickener is used in printing?

    Thickeners impart adhesivity and plasticity to the printing paste which can be applied on to the fabric without spreading and hold- ing the dye molecule at the desired place until the transfer of dye into the fabric and its fixation are complete.

  • What are chemical thickeners?

    Thickening agents, or thickeners, is the term applied to substances which increase the viscosity of a solution or liquid/solid mixture without substantially modifying its other properties; although most frequently applied to foods where the target property is taste, the term also is applicable to paints, inks, ...

  • What are the two main types of thickeners?

    There are two main types of thickening agent: starch-based (typically modified maize starch) and gum-based.
