دراسة مقارنة لجزيئات النانو المحضرة على تحسين الخواص الوظيفية للأقمشة القطنية المخلوطة

الملخص EN

This study aimed to prepare nanoparticles from metals and metal oxides and to identify the effect of the prepared nanoparticles to improve the functional properties of blended cotton fabrics (33% cotton, 67% polyester).

it has a plain weave structure 1 / 1.

the most important functional properties dealt with in the study included resistance to harmful ultraviolet rays-resistance to bacteria and fungi- resistance to stains and dirt.

silver and zinc oxide nanoparticles were prepared from silver nitrate and zinc acetate, respectively.

microscopic tests were carried out to identify and confirm the size and shape of the prepared nanoparticles by using the scanning electron microscope.

for the selected fabrics, and to confirm the results, the tests were carried out according to the standard specifications of textile tests.

these tests include (tensile strength and elongation when cutting, air permeability test, UV resistance test, gram-positive and gram-negative bacteria resistance test, stain and dirt resistance test and contact angle measurement, the specifications of the material used in the study and its specifications after treatment were identified.

the results of this study concluded that the use of silver nanoparticles in the treatment of mixed cotton fabrics has a high ability to resist gram-positive and gram-negative bacteria and achieved an improvement in all functional properties with a total quality factor of 78%.

where the resistance to stains and dirt, as well as the tensile strength and elongation when cutting.

however, it was not resistant to gram-positive and gram-negative bacteria and achieved an overall quality index of 75%.
