Abstract
Purpose
The purpose of this paper is to create computer models of magnetic micro‐ and nano‐fibres. The fibres are the base of textronics devices, such as sensors and actuators. The authors show how one can avoid painstaking work during manufacture process by initial preparing of computer models.
Design/methodology/approach
The paper presents correspondence between finite element method (FEM) and reluctance network method (RNM). The smooth transition is possible, due to homogeneous models of magnetic micro fibres based on FEM.
Findings
The paper describes the solution to accelerated designing and manufacturing process of magnetic micro‐fibres; it describes also how magnetic permeability of such fibers can be calculated and how to perform a homogenisation in models.
Originality/value
The authors present a new way of modelling magnetic micro‐fibers by combining FEM with RNM. So far, only calculations for the B/H curve of magnetic micro‐fibers have been performed, yet authors propose an innovative way for determination of magnetic micro‐fibers' parameters. Homogenisation of finite element models is the crucial part in the process of combining two different numerical methods.

Abstract
Examines the fifteenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Abstract
Purpose
A review on additive manufacturing (AM) of shape memory polymer composites (SMPCs) is put forward to highlight the progress made up to date, conduct a critical review and show the limitations and possible improvements in the different research areas within the different AM techniques. The purpose of this study is to identify academic and industrial opportunities.
Design/methodology/approach
This paper introduces the reader to three-dimensional (3 D) and four-dimensional printing of shape memory polymers (SMPs). Specifically, this review centres on manufacturing technologies based on material extrusion, photopolymerization, powder-based and lamination manufacturing processes. AM of SMPC was classified according to the nature of the filler material: particle dispersed, i.e. carbon, metallic and ceramic and long fibre reinforced materials, i.e. carbon fibres. This paper makes a distinction for multi-material printing with SMPs, as multi-functionality and exciting applications can be proposed through this method. Manufacturing strategies and technologies for SMPC are addressed in this review and opportunities in the research are highlighted.
Findings
This paper denotes the existing limitations in the current AM technologies and proposes several directions that will contribute to better use and improvements in the production of additive manufactured SMPC. With advances in AM technologies, gradient changes in material properties can open diverse applications of SMPC. Because of multi-material printing, co-manufacturing sensors to 3D printed smart structures can bring this technology a step closer to obtain full control of the shape memory effect and its characteristics. This paper discusses the novel developments in device and functional part design using SMPC, which should be aided with simple first stage design models followed by complex simulations for iterative and optimized design. A change in paradigm for designing complex structures is still to be made from engineers to exploit the full potential of additive manufactured SMPC structures.
Originality/value
Advances in AM have opened the gateway to the potential design and fabrication of functional parts with SMPs and their composites. There have been many publications and reviews conducted in this area; yet, many mainly focus on SMPs and reserve a small section to SMPC. This paper presents a comprehensive review directed solely on the AM of SMPC while highlighting the research opportunities.

– This paper aims to evaluate the antibacterial properties of pigment printed fabric loaded with nano-sized silver and zinc.
Abstract
Purpose
This paper aims to evaluate the antibacterial properties of pigment printed fabric loaded with nano-sized silver and zinc.
Design/methodology/approach
The pigment printing paste was mixed with nano-sized silver/zinc particles and applied to the cotton fabrics by the hand screen-printing technique. The nano-sized particles, distribution on the fabric surface, were analysed by scanning electron microscopy and energy-dispersive X-ray spectroscopy. The ASTM E2149-01 test method was used to determine the bacteriodynamic activity of the treated fabrics. The wash and light fastness properties of the treated fabrics were investigated.
Findings
The experimental results of the study showed that antibacterial properties could be obtained by loading with nano-size silver/zinc particles on pigment printed cotton fabrics. There is no negative or positive effect of the addition of nano silver/zinc particles to the printing paste on fastness properties.
Research limitations/implications
The nano-sized metal particles and pigment printing paste should be well mixed to achieve uniform distribution on the printed surface.
Practical implications
The described process marks the introduction of a nano-technological aspect to pigment printing by its application to cotton fabrics.
Originality/value
The novelty/originality of the study lies in the new application process of nano-size silver/zinc particles to the textile pigment printing for antibacterial properties.
