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
