Nylon staining inhibitor for dyeing of nylon/cellulose blends
Neoleve NYC-D (direct dyes, neutral fixation type reactive dyes) and NYC-R (reactive dyes)

Examples of Neoleve (anti-nylon staining agent) use according to dyeing method used

Method of use

Ways of using the two types of Neoleve vary depending on the mix ratio of nylon, the kind of substrate and dye concentration, however, the use of 1-3% o.w.f. is generally a standard.

Preliminary testing is necessary as Neoleve's anti-staining effect may deteriorate due to the simultaneous use of some leveling agents during dyeing of nylon.
