NR-300 is a special structure nylon retarding agent developed by
our company. NR-300 has wide application range, excellent levelness
and self-cleaning characteristics of dyed fabrics and NR-300 has
good resistance function when the nylon dyeing temperature is about
60~70℃.Especially in acid, complexation, neutral, direct, reactive
dyes and in dyed wool / nylon, silk / nylon, and other blended or
interwoven fabric has significant effect.

Characteristics and Applications
1. NR-300 has good retarding and dye transfer function, can be used
of levelling agent for wool, silk, nylon and its blends.
2. NR-300 has excellent purification, to float colour, colour
repair function, and can be used of colour repairing agent for
wool, silk, nylon and its blends.

5. By NR-300 dyed fabric shade bright, colour yield.
6. NR-300 has excellent salt tolerance and excellent resistance to
7. NR-300 has low foam properties.
The optimum usage of NR-300 varies with the type of dyed fabric,
processing technology, and dyeing equipment. Generally based on
0.5-1% o.w.f used as levelling agent; based on 1-3% o.w.f used as a
colouring agent; based on 2-4g/L used as Nylon retarding agent, and
appropriate to increase or decrease.
