Coating of conductive yarns for electro-textile applications

Conductive yarns are used for integration of sensors and other electronic devices with textile fabrics through weaving, knitting, braiding or embroidery processes. In the lifetime of the textile also several washing cycles might occur. These processes involve rubbing which may lead to displacement of conductive fibres, causing short circuiting between the neighbouring conductive fibres. Also the textile products made with conductive fibres may have to work in the presence of water, where the exposed conductive fibres can get short circuited. In this work, an attempt has been made to protect silver-coated polyamide yarns with polypropylene (PP). This is done through wrapping the PP staple fibres around the silver-coated polyamide yarns through friction spinning and melting the PP sheath fibres in an oven. The influence of twist in the conductive yarns, amount of PP coating and the oven temperature during coating process on the tenacity, electrical insulation in the presence of water and flexibility properties of the coated yarns are studied. The PP coated yarns with plied conductive yarn in the core provide better flexibility but need higher amount of coating to provide complete electrical insulation in the presence of water as compared to those yarns with single conductive yarn in the core.

Design and fabrication of touch-sensitive polymeric optical fibre (POF) fabric

Polymeric optical fibres (POFs) can be integrated into a textile structure for illuminative fashion and interior fabric applications. In this study, the development of a touch-sensitive POF fabric system through the integration of conductive yarns and an electronic controlling system was explored. Distinct from conventional sensor applications, the capacitive sensor used in this study was embedded into the textile structure using conductive yarns via experimentations with different weave structures. With the embedded controlling system and RGB light-emitting diodes, the POF fabrics were able to transfer sensory signals into illumination. This study combined novel weaving techniques, different materials and electronic system development to develop a multi-touch interface based on textile capacitive sensors that can sense both touch contact and non-contact/proximity. The final prototype can be washed up to 10 laundry cycles. The results demonstrated that multiple functionalities can be integrated into the structure to produce an interactive textile based product.

This issue of Textile Progress reviews research carried out on electrically conducting polymers, fibres and fabrics prepared by in situ chemical, electrochemical and vapour-phase polymerisation. It provides information about various inherently conducting polymers prepared from aniline, pyrrole, thiophene and their derivatives that are often used to prepare flexible non-metallic electro-conductive textiles. Several methods for the characterisation of electro-conductive fabrics are included, namely scanning electron microscopy, X-ray diffraction, elemental disruptive X-ray analysis and Fourier transmission infrared spectroscopy. The role of the polymerisation process in determining the electrical properties of electro-conductive textiles is examined.

Measurement of the Transverse Mechanical Properties of High-performance Fibres

The measurement of the transverse modulus of single fibres having a diameter of 5–15 μm has become possible by the development of a new instrument. An account is given in this paper of an investigation of some typical high-performance fibres for their transverse modulus and their fibre strength in transverse compression. The high-performance fibres studied were aramid fibres having different longitudinal moduli, pitch and PAN carbon fibres, also of different modulus values, and some other reference fibres. These fibres had strong anisotropy in the longitudinal and transverse directions to the fibre axis, and there was correlation between the two directional moduli. The transverse strength by the two directional moduli. The transverse strength by compression was also investigated for these fibres. Organic fibres of highly oriented polymers showed a ductile property in transverse compression and had a yielding stress, but carbon and ceramic fibres showed brittle behaviour in compression. A correlation between the yield stress or breaking stress and the transverse modulus was found for these fibres.
