A novel yarn spinning method for fabricating conductive and nanofiber-coated hybrid yarns

Abstract

Electronic or conductive textiles have attracted particular attention because of their potential applications in the fields of energy storage, supercapacitors, solar cells, health care devices, etc. Contrary to solid materials, the properties of textile materials such as stretchability, foldability, washability, etc. make the textiles ideal support materials for electronic devices. Therefore, in recent years, various conductive materials and production methods have been researched extensively to make the textiles conductive. In the present study, an alternative method based on imparting the conductivity to the fiber-based structure for the production of conductive textiles was established. Considering the contribution of unique characteristics of the fiber-based structure to the clothing systems, imparting the conductivity to the fibrous structure before yarn and fabric production may help to protect the breathable, lightweight, softness, deformable and washable of textile structure, and hence to improve the wearability properties of the electronic textiles. In the study, carbon black nanoparticles were selected as a conductive material due to low cost and easy procurable while cotton fiber together with other fiber types such as polyester, acrylic and viscose rayon fibers were used due to their common usage in the textile industry. In addition, various production parameters (CB concentration, feeding rate, etc.) were analyzed and the results indicated that the developed alternative method is capable to produce conductive yarns and electrical resistance of the yarns was about 94–4481 kΩ. The yarns had comparable yarn tenacity and breaking elongation properties, and still carried conductive character even after washing. In literature, there has been no effort to get conductivity in this manner and the method can be considered to be a new application for added-on or built-in future wearable electronics. Also, in the study, produced conductive yarns were used as a collector to gather the nanofibers onto the yarn to produce hybrid yarns enabling the production of functional textile products.

Electrospun poly (lactic acid) -cotton core-shell yarns: Processing, morphology, and mechanical properties

“…Recently, several studies have been conducted to produce nanofiber-coated yarns as the base material for fabric weaving. 9,[34][35][36][37] Contrary to the growing interest on this research field, it is not yet clearly understood how the structure of the core yarn or shell contribute to the final mechanical function of the resultant yarn. In addition, aiming to improve the geometrical structure, entanglement of the layers, integrity, and hence, the physical-mechanical performance of the core-shell yarns, more attempts are required to perform for efficient fiber depositing, arranging, and assembling into a yarn.…”

A Novel Method For The Fibre-Based Conductive Ring Spun Yarn Production

“…Therefore, the method used within the scope of the study, it is the rst time in the literature that the bre structures gain conductivity by applying graphene-based nanosuspension. In our previous study, conductive yarns were produced with the alternative method using carbon black particles (Kayabaşı et al 2020). Unlike the literature, with the developed alternative method, it is aimed to gain conductivity to spun yarns consisting of staple bers such as viscose, cotton, polyester etc.…”

“…1 However, due to their remarkable performance, such as high specific surface area, excellent flexibility and porosity, nanofibrous membranes are still extensively applied in various industries, including filtration, 2,3 sensors, 4,5 biomedicine, 6,7 energy devices 8,9 and the textile industry. 10,11 For example, corncob-like and phase-changeable nanofibrous membranes make clothes more comfortable and have an outstanding protection capability. 12 The superior thermo-conductive, breathable and superhydrophobic nanofibrous membrane is used for personal cooling.…”
