Nylofix - BPF is a Bisphenol free wet fastness improver for metal complex & acid dyes on nylon, wool, silk and blends. Unlike conventional tannic acid and tartar emetic fixing method, it enables one bath fixing and therefore fixing process and time can be shortened. It is suitable for dipping and continuous method and does not change color shade or tone. It can prevent staining of white area. Nylofix - BPF is an excellent reserving agent for synthetic and natural polyamides.
Add Nylofix - BPF into the bath, adjust the pH to 4.5 – 5 (with acetic acid or formic acid), and treat at 50
- 55ºC for 30 mins.
Important Note:
Substrates which are to be laminated or coated with foam should not be after treated with condensation products of the Nylofix - BPF type as this impairs adhesion.
Improvement in fastness properties with Nylofix - BPF :
Improving the wet fastness properties of basic dyeable polyamide dyed with cationic dyes.
Application
The wet fastness properties of anionic modified polyamide dyed with cationic dyes can be improved by after treatment with
General:
When dyeing polyamide /cellulosic blends in the one bath or one bath two-step process, Nylofix - BPF can be used a reserving agent to prevent direct dyes staining the polyamide component.
Amount required:
Dye with an addition
- Nylofix - BPF : 0.5 – 0.75 %
Method:
Because of the excellent reserving effect of Nylofix - BPF on special dye selection is necessary. However, its reserving action may be reduced if non-ionic leveling agents are use.

Apply Nylofix - BPF after alkaline after scouring of print, a cationic scouring agent like Altrasperse-SW, before after treatment, set a cold bath with,
To remove any residue of the cationic scouring agent and any loose anionic dye from the substrate, then after treat with,
In continuous after treatment, e.g. padding (dry-on-wet or wet-on-wet) this should be regulated through liquor pick-up
