Washing processes,
detergant agents, washing cycles and temperatures can often cause damage on
fabrics. The aim of this work was to determine chemical and physical changes on
cotton fabrics with different washing conditions. A Box–Bhenken statistical
design was used to evaluate the effect of washing temperature (40 -50-60°C),
number of washing (10, 30, 50) and washing agent (only water, base detergent,
detergent with bleaching agent) on the average degree of polymerization. The
effect of multiple washes on cotton fabrics was evaluated by means of average
polymerization degree, tensile strength, whiteness index and scanning electron
microscopy. Whiteness index decreased significantly using with base detergent
and bleaching agent containing detergent,
whereas washing with only water did not affect significantly to
whiteness index, with increasing number of washing. However, temperature (p
> 0.05) individually were not found statistically significant for whiteness
index. As number of washing and temperature increased, tensile strength values
decreased. Also, washing agent (p > 0.05) individually were not found
statistically significant for tensile strength. When evaluated in terms of
average polymerization degree values, after the washings with base detergent
and bleaching agent containing detergent, there is a greater decrease in the
average polymerization degree relative to the only water washings. While the
temperature increased in washing process, the average polymerization degree
decreased and the lowest average polymerization degree was obtained at 60 ˚C
and 50 washes. SEM images indicate that number of washing and the content of
detergent is an important parameter in the washing process. The worst image in
this study was obtained with 50 washes using detergent containing bleach.
Washing processes cause undesirable results on the surface of fabrics.
