Abstract

Nowadays the multifunction product has wide interest; whereas polyester fabric has a price cheap than natural fabric so it can achieve high effect according to its properties but hydrophobic nature still disadvantage; so silk like polyester is an important trend for the textile industry by modification fabric.
To reach the specific goal which create a novel properties; the following steps were done:
1. Polyester fabric was selected
2. Test wettability after hydrolysis of polyester fabric using sodium hydroxide via microwave irradiation and conventional technique
3. Test wettability after treated (untreated and hydrolyzed polyester fabrics) with zinc oxide dissolved in 4% acetic acid via microwave and conventional technique
4. Dyeing of (untreated polyester, hydrolyzed polyester, treated untreated polyester fabrics with ZnO and treated hydrolyzed polyester fabrics with ZnO) with disperses dye using (C.I. Disperse Blue 56) via microwave irradiation and conventional technique. It was observed the color strength of dyeing hydrolyzed polyester fabrics using microwave technique (K/S 26.59) is higher than conventional technique (K/S 24.45), whereas the blank was (K/S 21.91).
5. The fastness properties to wash, light and perspiration of dyed polyester fabric after finishing were evaluated, the results ranged from good to very good.
6. Quantitative antibacterial activity of the finished polyester fabric were evaluated against Gram positive and Gram negative bacteria (Stapehylococcus aureus, Escherichia coli); it was observed that the hydrolyzed polyester has bacteria reduction % (80.2 %, 72.56%) when using microwave technique, but when using conventional technique was (80.12%, 71.44%) for Gram positive and Gram negative bacteria. Otherwise their enhancement after finishing fabric with ZnO.
7. The values of ultraviolet protection factor (UPF) were evaluated for treated and untreated polyester fabric. It was found that the values for untreated polyester gave a good protection (31.7), otherwise their enhancement occurred after treated polyester fabric with ZnO.
8. The physico-mechanical properties (tensile strength, elongation, tear strength) of untreated, hydrolyzed polyester and treatment of hydrolyzed and untreated polyester fabric with ZnO were studied. The results showed a remarkable decreasing in tensile strength and tear strength after hydrolyzed fabric using microwave technique(from 83.3 to 79 kgf/5cm), tear strength (from 3300 to 1800 gm) , while after treated hydrolyzed polyester fabric with ZnO using microwave technique the results showed an increasing in tensile strength and tear strength (from 83.3 to 86.5 kg/5cm), tear strength ( from 3300 to 5875 kgf/gm) and tensile strength (from 83.3 to 89.3 kgf/5cm), tear strength ( from 3300 to 6450 kgf/m) when treated polyester fabric with ZnO using microwave technique.
9. Then, the durability of the finished fabric with ZnO against repeated laundering cycles were evaluated and the results showed that the antibacterial activity and the ultraviolet protection factor can be maintained even after 30 laundering cycles.
10. Seven designs including accessories were created for women clothes via pattern method. The hydrolyzed polyester and hydrolyzed polyester treated with ZnO using microwave technique were used to accomplish these designs and adding novel properties (Hydrophilicity, Antibacterial activity and U.V. protection). Tie-dye and embroidery with hand stitches were applied to create fashionable designs.
