Abstract Nanoclays are among the more important
industrial minerals. They are inexpensive, widely
available in nature, and environment friendly. Nano
kaolin (NK) is used to impart additional values of
viscose fabrics. The mentioned fabrics were treated
with different concentrations of NK using pad-dry
cure technique. The surface morphology and surface
chemical elements of treated as well as untreated
fabrics were investigated using scanning electron
microscopy and dispersive X-ray spectroscopy,
respectively. Tensile strength and elongation, thick-
ness, bending length, moisture regain and antimicro-
bial activity of the treated fabrics were evaluated. New
colouring material (Thiazolidin), direct and reactive
dyes were used for dyeing the treated and untreated
fabrics. K/S and washing fastness of the dyed fabrics
were assessed and statistically compared using t test.
The effect of treatment and dying on performance
properties of garments were evaluated by calculating
quality factor for each fabric.

Regenerated viscose fabrics and their blends have a
great effect on textile industry especially in clothing
sector due to their excellent hygroscopicity, breatha-
bility, silk-like feel, beautiful drape, and comfort.
Viscose ﬁber is the most important alternative for
cotton and other natural ﬁbers in many countries.
However, the disadvantages of viscose ﬁber are that
the ﬁber can be easily ignited (Doraiswamy et al.
lu and C¸ elik 2015). The crease resistance,
wet and dry tear strength of this type of ﬁber are also
poor (Shaikh et al. 2012).
Lots of studies have been carried out on viscose
fabrics to improve their physical and mechanical
properties including tensile and tear strength.
Recent studies are mainly focused on applying
nanotechnology in textile industry, instead of the
conventional methods (Ki et al. 2007), to produce
smart textile of multifunctional or special functions,
such as antibacterial, coloration, UV-protection (El-
Raﬁe et al. 2010; Emam et al. 2014; Rehan et al. 2015),
