Polyacrylonitrile (PAN) belongs to the group of polymers that are often used for electrospinning, as it can be applied as a pre-cursor for carbon nanofibres and is spinnable from the low-toxic solvent dimethyl sulfoxide (DMSO). While the influence of different spinning parameters on fibre morphology and mass per unit area was investigated in a previous study, here we report on the impact of the spinning solution, using DMSO as a solvent and wire-based (needleless) electrospinning. Our results show that a broad range of solid contents can be applied, providing the opportunity to tailor the fibre diameter distribution or to optimize the areal weight of the nanofibrous mat by changing this parameter, while the chemical composition of the fibres remains identical.

Working processes in the technological sewing process are performed on machine systems characterized by machine-manual work, where the worker and the machine work simultaneously. Such a work system requires a great deal of responsibility in terms of quality, quantity, and the accurate and timely execution of tasks, which requires the quick and accurate response and extremely good psychomotor and visual skills of workers. This paper presents the process of determining the working method and normal times for the technological operation of runstitching women’s blouse collars, which includes the design of an ergonomically designed workplace, the selection and technical equipment of the universal sewing machine and the determination of the optimal work method and normal times using the Methods-Time Measurement (MTM) system. The research results obtained indicate that the technical equipment of a universal sewing machine has a significant impact on the structure of the technological sewing operation and the working method, i.e. the number of auxiliary manual technological suboperations. Improving technical equipment, i.e. increasing the number of automated functions used on a universal sewing machine, reduces the number of auxiliary manual suboperations, reduces the time required to perform the technological operation and increases work productivity.

Elastic fi tted goods are identifi ed as a separate group of medical textiles. This group includes elastic bandages, abdominal binders, posture correctors, corsets, recliners, etc. Elastic knitted bands are widely used in rehabilitation and prophylactic goods. This research studied the properties of elastic warp knitted bands that were made on an 18E gauge crochet machine. In order to reduce the product weight and to increase its comfort, a partial set (2-in/1-out) of elastomeric threads is used. This yarn is the main component of elastic fabric that aff ects stretch properties and end-use. In the warp knitted band, the polyurethane thread is usually used as longitudinal inlay yarn, which is located between the loop’s overlap and underlap. In order to study the eff ect of polyurethane pre-elongation before knitting on band properties, seven pairs of gears were used and elongation was varied from 280% to 395%. The weft fi lling yarn connects the separate wales into the band. To prevent contact between polyurethane threads and the human body, the weft yarns were laid on both sides of the inlay yarn. The movements of weft guides were in opposite directions. In order to study the eff ect of weft yarn diameter on cover factor and bands properties, 2 ends, 4 ends or 6 ends of 16.7 tex polyester yarn were used to achieve corresponding overall linear densities of 33.4 tex, 66.8 tex and 100.2 tex. It was concluded that the partial drawing-in of the guide bar with polyurethane thread facilitated a reduction of up to 20% in the basis weight of the elastic band, while ensuring suffi cient stretch properties. The impact of technological factors on the structural parameters and properties of the elastic band was established.

The textile industry is considered one of the major environmental polluters, primarily due to the quantity and composition of wastewater. It is therefore important to examine its diff erent treatment methods. For this purpose, the isothermal adsorption of Reactive Black 5 dye on powdered activated carbon at 25(±1) °C and 45(±1) °C was carried out to determine the eff ect of initial dye concentration, contact time and temperature on the adsorption process. In order to investigate the mechanism of adsorption of Reactive Black 5 dye on activated carbon, kinetic studies have also been carried out. Experimental data were analysed using a pseudo-fi rst-order and pseudo-second-order kinetic models, as well as an intraparticle diff usion model. Standard Gibbs free energy values of the adsorption process were also calculated, while the morphological analysis of activated carbon before and after adsorption was performed using a scanning electron microscope. The effi ciency of activated carbon as an adsorbent for Reactive Black 5 dye is evidenced by the fact that more than 60% of dye is adsorbed after 30 minutes regardless of initial concentration and temperature. The experimental data also showed that adsorption is kinetically controlled assuming a pseudo-second-order process, and that intraparticle diff usion is not the only process that infl uences the adsorption rate. Negative values of standard Gibbs free energy indicate that the adsorption reaction is spontaneous, while a higher negative value for temperature of 45 °C compared to 25 °C shows that a higher temperature is more energetically favourable for the adsorption of Reactive Black 5.

Electrospun polyacrylonitrile (PAN) nanofi brous mats belong to typical precursor materials of carbon nanofi bres. They have, however, the problem that they need to be fi xed or even stretched during stabilisation and ideally also during carbonisation in order to avoid undesired conglutinations and deformations of the original nanofi bre morphology, resulting in brittle behaviour of the macroscopic nanofi brous mat, which impedes several applications. In an earlier investigation, blending PAN with ZnO was shown to increase fi bre diameters and lead to unproblematic stabilisation and carbonisation of nanofi brous mats. ZnO, on the other hand, may have a negative impact on biotechnological applications such as tissue engineering. Here, we thus report on the morphological and chemical modifi cations due to blending PAN electrospinning solutions with diff erent amounts of casein. By optimising the PAN : casein ratio, relatively thick, straight nanofi bres are obtained, which can be stabilised and carbonised unambiguously, without the well-known negative impact on cell adhesion due to the addition of ZnO.

The aim of this paper is to provide a simple MATLAB-based model to determine the real-time homogeneity of neppy mélange yarn fabrics. Currently, the mélange yarn industry relies solely on visual assessment and experience. This algorithm, however, proposes a solution for the mélange yarn industry. The designed algorithm presented in this paper, which is based on kernel density function and macropixel analysis, was implemented for the real-time nep detection of neppy mélange yarns and calculated an inhomogeneity of neps of around 91%. This strategy would be useful for the mélange yarn industry and can also be used in other types of fashion yarns.

Chemicals in nano-form are free from aggregates and low concentration eff ective. The nanoparticles of certain chemicals have been found to be of substantial importance for application in textiles as well as allied fi elds. Nano-silica is one of such nanoparticles possessing enormous potential for multi-functional application on cotton. However, the cost of nanoparticles is remarkably high, thus limiting their commercial applications. This study discusses the manufacture of silica nanoparticles in a laboratory, their characterisation, succeeded by their application on cotton. The performance was compared with those obtained with tailormade silica nanoparticles from manufacturers. It was found that laboratory-made silica nanoparticles are relatively capable of developing a parallel fi nishing eff ect on cotton compared to those obtained with tailormade silica nanoparticles.

Thermal resistance and moisture management characteristics are important attributes of textile materials for the characterisation of their ability to provide thermal comfort. Nettle fi bre consists of a hollow core that is expected to enable good thermal and moisture regulation properties. Nonwoven fabrics of three diff erent mass per unit area values, made from nettle, polyester and blends thereof, were prepared on a needlepunching machine, maintaining the same punch density and depth of penetration. The thermal conductivity, water vapour permeability, water retention, wicking, moisture management, drying rate and air permeability of these fabrics were evaluated. Nonwoven fabric prepared with 100% nettle fi bres exhibited good thermal conductivity, while polyester fabric demonstrated good thermal insulation. The nettle fi bre fabric showed good water retention, drying rate and moisture management properties. On the other hand, polyester-enriched fabric exhibited good wicking behaviour.

3D printing is considered to be the key technology for future production processes. It has recently found its way into the fi eld of the textile industry and promises to revolutionise the textile supply chain. It is of particular interest for the production of customised items and other structures which cannot be produced with common techniques. Large apparel companies have already integrated 3D printing into their manufacturing processes to print parts like soles and accessories. However, 3D printed garments that are ready to wear can still not be found. Due to the lack of suitable printing materials, research in 3D printed textiles is still in its initial stage. This research contributes to the development of 3D printed textiles by using Fused Deposition Modelling (FDM). In this study, a new method for printing textile-like surfaces was developed which combines diff erent materials into an interrelated fl exible structure. Several textile-like surfaces were designed on this basis and fi nally applied to a wearable garment. Furthermore, the advantages of 3D printing for the textile supply chain were demonstrated.

We frequently need to compare two or more colours, and we can rely only on the colour impression from our memory. Colours are not stored in our memories in their actual state and they can gradually be erased. This paper addresses the subject of short-term colour memory. The approach is based on an experiment where subjects observed a given colour for a certain period of time. The purpose of the research was to determine the relation between the reference colour, time delay and the accuracy in recalling of the colour from the subject’s memory. The colours studied in the research were presented with no association to bodies, shapes or textures. The main variables in the observing conditions were the basic colour parameters which defi ne the colour, i.e. hue, saturation and brightness. The analysis of the fi nal results showed that colour is not stored in our memories correctly and that it loses its basic parameters after 10 s. As the time delay increases, the accuracy of the colour impression in our memory diminishes. Colour is stored in our memory as clearer and more saturated. Bright colours are remembered as even brighter, while dark colours are stored as darker. The sensation of hue is generally stored very precisely, while the deviation in hue depends on the observed colour.
