Abstract
Nowadays, textile materials are expected to provide many additional functions. Such as UV protection, self cleaning , and antimicrobial finishing , In this perspective, chemical functional treatment is the most convenient process in textile manufacturing to bring in new performance and functions to regular textile fabrics, and contributes significantly in added values to the final textile products, most functional finishing technologies employed in textile treatments, are directly incorporating functional agents to textiles that impart special properties to final product. The present challenge is to face the textile functionalization as a global process, with balance of the different properties of the materials such as comfortability dyeability, fastness properties, antimicrobial characteristics, for instance. So, the present thesis aims to impart antimicrobial property to a three different fabrics by treatment with antimicrobial agent and using these different textile fabrics in performing fashionable women clothes. In order to achieve the goal multipurpose designs and the following steps were done:
1. Viscose, cotton and polyester fabrics were selected, taking into consideration the availability in Egyptian market.
2. Treating the fabrics (viscose, cotton and hydrolyzed polyester) with polyethylene glycol (PEG) using pad-dry-cure technique. Studying the conditions of treatment such as polyethylene glycol (PEG) molecular weight, concentration, citric acid concentration, curing time and curing temperature.
3. Treating the cotton fabric with oil – water repellency Rucostar® EEE, by pad-dry-cure technique, to reach the goal of different end use (medical use) through creating barrier effect.
4. Qualitative and quantitative antibacterial and antifungal activity of the modified fabrics were evaluated against gram negative bacteria (Echiricia.coli) and gram positive bacteria (Staphylococus.aureus), spore forming fungi (Aspergillus niger) and yeast (Candida albicans). It was found that the bacterial reduction (%) of viscose fabric reached (83%) for E.coli and (84%) for S.aureus and fungal reduction reached (58%) for A.niger and (28%) for C.ablicans and in case of cotton fabric the reduction reached (88%) for E.coli, (86%) for S.aureus, (64%) for A.niger and (31%) for C.ablicans and finally the polyester fabric gives (70%) for E.coli, (71%) for S.aureus , (53%) for A.niger and (21%) for C.ablicans reduction %.
5. The durability of the treated fabrics to repeated laundering cycles were evaluated and the result showed good durability for the treated fabrics even after 15 cycles.
6. The physical and mechanical properties (tensile, elongation, stiffness, tear resistance, crease recovery angles and air permeability) of viscose, cotton and polyester fabrics were evaluating before and after treatment. The result showed a decrease of tensile, elongation, and tear resistance and enhancement in the crease recovery angle and air permeability and a slight increase in fabric stiffness after the (PEG+ citric acid) treatment.7. Dyeing the viscose and cotton fabrics with C.I Reactive Blue 195 and C.I Direct Red 89 dyes before and after PEG treatment. The after treatment showed better color strength in both reactive and direct dyes.
8. Printing polyester fabric with transfer printing technique was done as well as studying the effect of PEG on the color strength (K/S) of the printed samples. The results showed that there was a slight increase in the (K/S) for both hydrolyzed polyester and treated samples.
9. It was observed that there is a slight increase of the antibacterial activity against gram positive and gram negative bacteria after dyeing cotton and viscose and no remarkable enhancement in case of printing polyester.
10. The fastness properties to wash, light and perspiration of dyed viscose and cotton fabrics before and after treatment were evaluated the results showed , that enhancement in the wash fastness in case of viscose and cotton fabrics with both reactive and direct dyes in case of printed polyester fabrics the results showed very good wash, light and perspiration properties .
11. The oil and water repellency where evaluated for cotton fabric treated with mixture of ( PEG+ citric acid) using Rucostar ®EEE and the result, showed that it gives good water repellency with PEG treatment. The cotton fabric was antibacterialy evaluated after this treatment and the results showed that there is an enhancement in the antibacterial activity in case of( PEG+ citric acid)+ Rucostar ®EEE compared with Rucostar ®EEE only.12. Eighteen designs were inspired from different sources; six designs of women clothes as well as their patterns have been done. The used fabrics were pre-dyed-post treated with (PEG+ citric acid) and then introduced to layout and cutting by using the designs pattern, the tie-dye, batik and stenciling techniques were used to achieve a desirable look stitching hand drawing, beads work and embroidery were also used.
