Effect of use Gaseous Laser on Natural and Mechanical Properties for some Cotton and Polyester Fabrics

A laser word is formed from the initial characters of the following English phrase : ‘ Light Amplification by the Stimulated emission of Radiation ‘
 
-          Laser radiation produces an increasing amplification of almost identical photons in distress , this amplification allows for a light intensity in the surface unit capable of physical alteration of the material .
-          The gaseous laser produced by Helium / Neon was used along a wave-length  λ = 632 nm  . it has a red color and has a weak ability to  obtain the laser beam and expose the cotton and polyester fabrics to this beam . and study the changes resulting from this exposure .
-          The  Helium / Neon laser is the first gas laser to come into existence , Neon in this mix play the role of lasers .
-          Cotton is selected as a natural raw material in Egypt , the polyester material was also selected as a widespread industrial chemical in Egypt .

The research studies the effect of the different speed and the number of times exposed to laser beams .
Practical experiments were measured at the national institute of laser sciences at cairo university , some experiments were also measured at the national research center .

 
The research was targeted :

Effect of increasing the speed and number of times exposed to the laser samples  .
Effect of exposure to textile samples to laser on mechanical properties of fabrics .
Effect of exposure to textile samples to laser on natural properties of fabrics .
Comparison of samples of natural fabrics and industrial fabrics samples after exposure to laser beam .
