Fixers & Thickeners

A block silicone softener releases its softening action gradually and in a controlled way during curing, giving manufacturers more predictable and even results. Regular unblocked silicone can release its effect too quickly, which can sometimes cause an uneven or greasy feel if not handled carefully.

Dyne Chemicals LLP is a textile thickener manufacturer based in Chhatral, Gandhinagar, Gujarat, and it also makes the fixers that work alongside its thickeners. Every grade is developed in its own R&D lab and produced at its own facility. That control over formulation allows Dyne to give printers consistent viscosity, colour fastness and print definition from one batch to the next.

A thickener sets the viscosity of the print paste. It keeps the design sharp as the paste passes through the screen and stops colour from bleeding beyond the print outline. A fixer strengthens the bond between the colourant and the fibre, which improves wash and rub fastness on the finished fabric. Since both work inside the same paste system, printers get more reliable results when the two are selected and tested together.

For reactive printing, Dyne offers the hybrid thickeners Dyne RPG 100, RPG 200, RPG 300 and RPG 400, which combine alginate with synthetic polymer. Dyne RPG 8200 is a synthetic reactive thickener that is ready to use and compatible with automatic dispensing systems. Pigment printers can choose Dyne Thick 1200 for high viscosity and sharp definition, or Dyne Thick 1500 for smooth flow and strong colour yield. To complete the range, Dyne Fix 300 Eco is a zero formaldehyde pigment fixer that improves wash fastness.

Dyne formulations are aligned with GOTS, OEKO-TEX ECO PASSPORT and ZDHC MRSL, and they are free of APEO and NPEO. Dyne Fix 300 Eco contains zero formaldehyde, which matters to exporters supplying brands with strict formaldehyde limits. Because certificates apply to individual products, mills should tell the Dyne team which standard their buyer requires and ask for the documents for the exact grade they plan to use.

Dyne RPG 300 and RPG 400 are built for reactive printing on rayon and cotton wovens, and they also work in reactive digital printing and fabric pre-padding. RPG 8200 suits mills running bulk reactive production with automatic dispensing. On the pigment side, the Thick 1200 and Thick 1500 grades handle the paste, while Dyne Fix 300 Eco improves wash durability. For other fabric and process combinations, the Dyne technical team can advise during sampling.

Four inputs decide the choice: the fabric, the dye or pigment class, the printing method and speed, and the compliance standard your buyer has set. Once these are clear, test the thickener and fixer together with the rest of the paste on your own fabric before bulk production, since compatibility affects both colour yield and fastness. The Dyne technical team can recommend a starting combination from these details.
