In this research aniline polymerization conditions were optimized in presence of pre-treated polyester textile to achieve as high electrical conductivity as 100 S/Cm. Alkaline activation of the polyester textile was followed by immersion in to aqueous acidic solution of aniline monomer. Then the oxidant solution was used to initiate the polymerization. Finally, the prepared product was washed and dried prior to ant test. Functional groups were studied by Fourie-transformed infrared spectrometry (FTIR) from the surface of the polyaniline coated textile. Also, morphological structure of synthesized conductive polyaniline was studied by scanning electron microscopy (SEM). The synthesized cloth was used in a closed circuit in order to light up alight emitting diode to emphasis the conductivity of the textile and fibres that synthesised by this method.

Abstract: Composite materials are playing a greater role in engineering application due to their optimized structure and mechanical characteristics. Study here aims at composite design which enables the fabricated composite to have excellent mechanical behavior even in extremely corrosive environment, for example, environment with extremely high ozone gas concentration. To take advantage of the great anticorrosion property of pure aluminum (Al), PET thin film coated with pure aluminum (Al) on its surface has been introduced as the top layer of the fabricated composite with polyester textile as the middle layer. To bond these layers together, the composites with this sandwiched structure are manufactured at different temperature. Main purpose of the study is to evaluate the influence of processing temperatures on the mechanical properties of the manufactured composites, and on their failure behavior. In this way, optimized processing temperature may be found.

Textile Fabric

This study intended to develop a healthy and environmentally friendly super-hydrophobic PET polyester textile fabric using a specific Fluoro Silane finish (SHF). A novel SHF was prepared and applied on a polyester fabric using a pad-dry-cure method. The finished fabric was evaluated for the degree of hydrophobicity, durability and stain repellence. The finished fabric exhibited static water contact angle greater than 170o and received 90 AATCC (4 ISO) rating that is recognized as super-hydrophobicity and this property was maintained even after a 50,000-cycle abrasion test. FTIR analysis identified the characteristic peaks related to Si-O-Si and C-F asymmetric stretching bands of the finish on the fabric indicating a robust attachment on the fabric. Finished fabric did not show any change in appearance or tactile characteristics of the fabric.

Polyester Textile

Polyester textiles usually have excellent mechanical properties. However, their mechanical behaviors under extreme conditions such as in the environment with high ozone concentration usually decay after a certain time period. Aiming at increasing the mechanical behavior of commercial polyester textiles under extreme conditions, a PET thin film coated with pure aluminum (Al) on its surface has been introduced as the top layer of the fabricated material with polyester textile as the middle layer. Main purpose of the study is to evaluate the role of aluminum thin film on the surface in improving the mechanical behavior of the polyester textiles after they have been exposed in the environment with extremely high concentration of ozone gas.

Wearability of polyester textile is very outstanding in chemical fabric；silkworm pupae protein has good biocompatibility. In order to make a new kind of polyester textile which not only has good wearability, but also has good biocompatibility, the polyester fibers were semi-encased with sucrose ester to endue polyester fibers with reacting hydroxyl groups, and then silkworm pupae protein was grafted on surface of polyester fiber textile with a crosslinkage compound in this study. The structure of polyester textile grafted with silkworm pupae protein were studied by SEM, X-ray diffraction and differential scanning calorimetry(DSC). The polyester fibers were enclosed by layer of materials in SEM, X-ray diffraction showed silkworm pupae protein was random coil conformation, DSC exhibited the thermal property of polyester fibers almost did not change. The wearability of polyester fabric grafted silkworm pupae protein was measured too. With the increase of grafting silkworm pupae protein rate on polyester fabric, moisture permeability of polyester fabric increased firstly and decreased a little subsequently, the moister regain increased monotonously, the cockle elasticity decreased a little, the whiteness almost did not change, and flexural stiffness increased a little.
