Abstract: In this research, the main aim is to investigate the
antimicrobial effectiveness of ammonyx solutions finishing on
Sweatshirt Sport with immersion method. 60 Male healthy subjects
(football player) participated in this study. They were dressed in a
Sweatshirt for 14 days and some microbes found on them were
investigated. The antimicrobial effect of different ammonyx
solutions(1/100, 1/500, 1/1000, 1/2000 v/v solutions of Ammonyx)
on the identified microbes was studied by the zone inhabitation
method in vitro. In the next step the Sweatshirt Sports were treated
with the same different solutions of ammonyx and the antimicrobial
effectiveness was assessed by colony count method in different times
and the results were compared whit untreated ones. Some mechanical
properties of treated cotton/polyester yarn that used in Sweatshirt
Sport were measured after 30 days and were compared with
untreated one. Finally after finishing, scanning electron microscopy
(SEM) was used to compare the surfaces of the finished and
unfinished specimens. The results showed the presence of five
pathogenic microbes on Sweatshirt Sports such as Escherichia coli,
Staphylococcus aureus, Aspergillus, Mucor and Candida. The
inhalation time for treated on Sweatshirt Sports improved. The
amount of colony growth on treated clothes reduced considerably
and moreover the mechanical tests results showed no significant
deterioration effect of studies properties in comparison to the
untreated yarn. The visual examination of the SEM indicated that the
antimicrobial treatments were applied usefully to fabrics.
Abstract: Protective clothing limits heat transfer and hampers
task performance due to the increased weight. Militarism protective
clothing enables humans to operate in adverse environments. In the
selection and evaluation of militarism protective clothing attention
should be given to heat strain, ergonomic and fit issues next to the
actual protection it offers.
Fifty Male healthy subjects participated in the study. The subjects
were dressed in shorts, T-shirts, socks, sneakers and four deferent
kinds of militarism protective clothing such as CS, CSB, CS with
NBC protection and CS with NBC- protection added.
Ergonomically and psychological strains of every four cloths were
investigated on subjects by walking on a treadmill (7km/hour) with a
19.7 kg backpack. As a result of these tests were showed that, the
highest heart rate was found wearing the NBC-protection added
outfit, the highest temperatures were observed wearing NBCprotection
added, followed by respectively CS with NBC protection,
CSB and CS and the highest value for thermal comfort (implying
worst thermal comfort) was observed wearing NBC-protection
added.
