kind of polyamide fiber. Their molecular ends are - NH 2 and - COOH,
respectively. It can be dyed or printed with weak acid dyes, neutral dyes,
direct dyes, release dyes, reactive dyes and vat dyes. When nylon is dyed with
direct dyes, the brightness is low and the fastness to wet treatment is poor, so
it is generally not used. When dyeing with reactive dyes, nylon can only be used
for light colors, because it has fewer reactive groups and lower color yield.
Disperse dyes have weak binding force with nylon and poor fastness to wet
treatment, so they can only be used in light colors. Weak acid dyes and neutral
dyes are usually used to dye nylon into medium and dark colors. Weak acid dyes
and neutral dyes are usually used for nylon fabric printing, and some choose
direct dyes or cationic dyes. Weak acid dyes have bright colors, high fastness
to wet treatment, wide chromatographic range and convenient use. Neutral dyes
are used for medium and dark color printing because of their excellent sunlight
resistance, but their levelness is poor. Therefore, in color matching, varieties
with similar affinity and diffusivity should be selected. Nylon contains a large
number of amino and carboxyl groups, which are cations in acidic media. Due to
the Coulomb gravity, anionic dyes adsorb and bind with nylon under high
temperature steam.Yoga Top website:http://www.yoga-manufacturer.com/yoga-top/
