Textile/Polymer Composites of Some Protective Properties Prepared by Chemical and Radiation Treatments
Saleh Nagy El-sayed Saleh;
Abstract
The present work was under taken to impart different protected finishes for cotton and cotton/polyester fabrics for using in the fields of antimicrobial, fire retardancy and UV protection. These finishes were carried out via treatments with nanocomposites based on blends loaded with different additives under the effect of gamma irradiation. An important objective is that these finishes do not affect the original properties but enhances these properties. The present work falls in three parts and the important results obtained may be classified as follows:
Part 1
Antibacterial functionalization of cotton and cotton/polyester fabrics applying hybrid coating of copper/chitosan nanocomposites loaded polymer blends via gamma irradiation
Textile fabrics especially those based on natural fibers such as cotton and wool, can act as a media for the growth of microorganisms. Natural textile materials can be exposed to contamination with microbes (bacteria, fungi, algae) during production, usage or storage. The microbial attack of textiles leads to quality losses due to changes of color and appearance or to reduction in strength. The contact with the human body also, such materials offer an ideal environment for microbial growth because of their large surface area and ability to retain oxygen, moisture and warmth. Therefore, the antimicrobial finishing of natural fabrics has attracted much attention in recent years.
In this part, copper/chitosan nanocomposites (Cu/CS) were prepared in an aqueous solution in the presence of CS as stabilizer and CuSO4·5H2O precursor. Cotton and cotton/polyester fabrics were gamma-radiation grafted by padding to pickup of 100%, in nanocomposites based on Cu/CS NPs loaded in polymer blends of poly(vinyl alcohol) (PVA) and plasticized starch (PLST). The coated fabrics were characterized in terms of tensile mechanical, crease recovery and water absorption properties. The important results may be summarized as follows:
