| Abstract | ||||
| Improvement of some properties of both bleached and /or mercerized Egyptian Giza 89, and Giza 80 cotton fabrics using acrylic acid (M), as a finishing agent in the presence of potassium peroxodisulphate solution (K2S208), and sodium dihydrogen phosphate (NaH2PO4) in a combination employing a bad-dry-cure technique, followed by The addition of known concentration of chromium salt (K2Gr202), or an amine salt (tetra methyl ammonium chloride), as a UV protection agents in the dyeing bath was studied. To produce most balanced improvement in the fabric properties, the samples were treated with M (8%.), at pH 5-7, batching time 20-45 minutes, followed by drying of the batched samples at 95t for 5 minutes, then curing at 140t for 90 seconds. The factors affecting the cotton fabric properties such as pH, batching time, cotton fabric pretreatment, and M finishing on tensile strength, elongation%, dyeing and fastness properties were studied. Also, the effect of chromium and amine salts on the UV protection value was studied. The results obtained revealed that the major improvements in the cotton fabrics were: weight gain, basic dye uptake (K/S) value, high fastness properties, high tensile strength and elongation%, and high UV-protection value. It has been noted that the mercerized Giza 89 shows good properties than the other treated samples. | ||||
