Plain weave fabrics of polyacrylonitrile pre-oxidation yarns (PANOF) were prepared by small rapier loom. The flame retardation properties, mechanical properties and wear behaviors of PANOF plain weave fabrics were tested. The limiting oxygen index (LOI) of these PANOF plain weave fabric samples was 31%, which meets the criterion of flame-retardant fabrics. These fabrics neither melt nor shrunk when left in flame for a short period of time and the fabric structures were well maintained. Compared with flammable polyacrylonitrile fabrics, the polyacrylonitrile pre-oxidation fabrics exhibited excellent flame retardation properties, with satisfactory mechanical properties and comfortable handle.

In this paper, the influence of thermal fixation of woven interlining on the quality of woven fabrics, evaluated from the aspect of their dc volume electrical resistivity, was investigated. The plain weave fabrics made from cotton, flax, viscose, polyester, and cotton/polyester blends and 3/1S twill weave fabric obtained from cotton and polyester fibers blend were investigated. A cotton fabric with a point-applied thermoplastic binder was used as an interlining. The obtained results showed that the dc volume electrical resistivity of fabrics is influenced by their chemical composition, type of weave, type of yarn, fabric density which is especially pronounced in the interlining, the process of thermal fixation of the interlining, and ambient air humidity. The thermal fixation of the woven interlining greatly reduces the dc volume electrical resistivity of polyester fabric (499 times in the warp direction and 860 times in the weft direction), and increases the resistivity of other fabrics in the range of 1.3 times for viscose fabric and fabric obtained from cotton and polyester fibers blend in plain weave to 3.9 times for twill weave fabric. Based on the conducted investigation, it can be concluded that the quality of the tested fabrics evaluated from the aspect of their electrical resistivities, was significantly improved in the case of polyester fabric i.e worsens in the other investigated fabrics after thermal fixation of the woven interlining.
