For the production of technical textiles with demanding industrial applications, mineral fibre yarns, and carbon fibre yarns are used, among others. Various metal wires are also the starting material for such products and are in widespread use, "Textile technology knits what cannot be bent and shaped".

With an unlimited structural design, flat knitting offers technological advantages in the production of hoses made of technical materials and complex components, such as profiled hoses. For the production of technical textiles with demanding industrial use, mineral fibre yarns and carbon fibre yarns are, among others, used. Various metal wires are also the starting material for such products and are in widespread use, "Textile technology knits what cannot be bent and shaped".

The processing of mineral fibre yarns into multi-chamber hoses or knitted profile hoses, with a continuously inserted core, presents a special technical challenge. The innovative focus of the new flat knitting machine is the device for the continuous feeding of endless core components.

The production of multi-chamber hoses, with a continuously inserted core, is currently carried out in several operations:

1. Production of the knitted tubes

2. Insertion of the core component

3. Sewing over the entire length to fix the core component and produce the profile adapted to the application.

This method is not only time-consuming but also cost-intensive. So far, there is no possibility to automate this process in one step and make the production of profile hoses feasible on flat knitting machines.  By using the feeding device in combination with the needle selection technique, complex profile hoses with one or more different cores can be produced in one operation. This makes the production of such complex profile hoses more cost-effective and efficient. In addition, the development of innovative new products is possible.

Highly specified digital control tools for the customization of knitted fabrics is an existing technology, widely used industrially by trained knitters.

Some fabrication challenges inhibit the extent of use of digital customization for knitted pr­oducts on a mass scale, specifically when complex multiple structured knits are involved. This is due, in part, to physical changes that occur in the overall fabric dimensions, when stitch combinations with different physical attributes are combined within the same fabric. Existing computational tools fail to assist in the simulation and prediction of these overall deformations and the industry as a whole relies on the expertise of highly trained individuals.

The outline shape of the fabric is of specific importance as it is commonly preconfigured to a specific shape and dimension that must be reproducible. In this work, we propose a computational parametric tool for digitally designing and industrially producing knitted fabrics, creating a direct link between design and manufacturability.

The tool includes an integrated physical simulation component for estimating the fabric deformation. It allows users to control different methods of dimensional compensations for each structure within the design and visualize the outcome of the fabric structure. This allows for a better match between the initial graphic intent of the design and the actual physical knitted fabric outcome. Our approach aims to reduce the number of iteration cycles for knitting material samples, especially when knitting highly varied designs and to pave the path for a more streamlined design to manufacture process.

Temperature-sensitive products such as refrigerated and frozen goods pose particular challenges for logistics. Against the background of the mobility shift towards electric vehicles and the current challenges of temperature-stable transport in the field of pharmaceutical, esp. vaccine logistics in the context of the SARS-CoV-2 pandemic, new, energy-efficient vehicle equipment is needed to maintain cold chains. Known refrigeration concepts are designed to cool the entire cargo hold.

In addition, the goods cannot be removed from the vehicle while maintaining the cold chain. An insulating effect of containers is typically achieved by using foamed polystyrene (Styrofoam containers). On one hand, these structures have a very good insulating effect, but on the other hand, they cannot be reduced in volume during recirculation and are problematic with regard to recycling. The aim of the research presented here is therefore to develop a knitted box that is designed as a volume-reducible, rigid but foldable box.

This can be used as a supplement to existing transport container systems and therefore can be inserted in the transport container. The knitted box performs as insulation when the transported goods are actively cooled inside the box. It is a more sustainable and flexible alternative to existing insulation solutions. Knitted fabrics, especially spacer fabrics, have advantageous thermo-physical properties for this application due to their structural design.

In the course of a research project, various spacer fabrics were tested for their thermo-physical suitability as insulation materials. It was found that knitted predetermined folding lines represent an insulation gap. Based on this, a new structure was developed which, due to its structural design, compensates for cold or thermal bridges at vertices and edges of the box. The results show that the knitted corrugated structure insulates better than the knitted spacer fabrics with predetermined folding lines. A thermal imaging camera was also used to identify critical points for heat transfer.

To simulate the warp-knitted product with a specific shape, a mesh-based model for the modelling and simulation is proposed. The three-dimensional geometry of the final fabric is represented as a set of mesh of polygons, each of them containing information about the 3D orientation of the yarns in the warp knitted structure. Using spatial mapping, stitch coordinates from the flat mesh model to the three-dimensional mesh model are transformed and the final rendering is accomplished. The method provides yarn level data for the complete structure and can be used for speeding up the design process of clothing with warp-knitted products.

Modern consumers of textile products expect fast changing trends, a good availability of products and a larger supply. These expectations make it necessary to shorten the time-to-market significantly. However, the duration of the manufacturing process of a knitted fabric is largely determined by the complexity of the pattern and its related material intensity.

To shorten the production time of known knitting patterns, but also to produce completely new binding types a research team developed an innovative thread supply technology, which was patented in 2018 and funded by the European Regional development Fund (ERDF) as a R&D-project (Funding reference: EFRE-0400310).  The presentation introduces the validation process of the patented technology and therefore brings the theoretical considerations into a practical application. The thread supply technology enables the production of a so-called “Doubleface” fabric on flat as well as circular knitting machines. This double-faced fabric consists of two single-faced fabric sides which are knitted by a first yarn in the front needle bed and a second yarn in the rear needle bed. These two fabrics are joined by a third yarn knitting in both needle beds in the same carriage stroke.

This process can generate completely new structures. The method ensures that up to three yarns knit in one system pass. Furthermore, a fourth yarn can be implemented to insert an inlay yarn. The new patterning possibilities arising from the new technology will be presented on the congress.

In addition, the two single-faced fabrics can be produced simultaneously in the same carriage stroke in the front and rear needle bed, separated from each other and followed by a carriage stroke knitting in both needle beds. In this case fewer carriage strokes are required for knitting standard structures such as Milano Rib. This structure can be produced one third faster than with conventional methods.

Yarn tension during knitting has a profound impact on fabric quality. Modern high-speed circular knitting machines are mostly equipped with positive feed system, where a predetermined length of yarn is supplied to knitting zone to obtain uniform course length or stitch length (SL). Since SL is theoretically dependent on the stitch cam setting, the constant yarn delivery rate from the positive feed units results different yarn input tension (YIT)- the tension under which yarn is delivered to the knitting zone.

Moreover, using various types of yarn in the same machine may add a noticeable influence on YIT. A plethora of studies addressed yarn tension of the different regions of yarn path instead of dynamic yarn tension for the whole yarn path (i.e., yarn package to knitting needles). This empirical study aimed to determine dynamic yarn tension for the whole yarn path during knitting machine running state and has developed a mathematical model. The comprehensive mathematical model revealed a sum of around 20 knitting variables and constants, that are contributing to YIT at any point of knitting.

The impact of different variables and their interdependence have been theoretically evaluated. Finally, the developed model is expected to justify the reasons of yarn tension fluctuation in a circular knitting machine and thereby act as a key proactive approach for quality control purposes.

In this research, attention was focused on the preference for repetition of ornament and preference of colours as well as physical fabric properties of Croatian traditional knitwear. A total of 165 knitted pieces of clothing were found in the Department for Preservation, Reconstruction and Lending of Traditional Costumes in Zagreb; vests, sweaters, slippers, scarves, knitted coats, socks, and decorative wristbands.

The appropriate non-destructive research methods were used since the traditional textile must not be damaged. White yarn, dark blue, burgundy, red, and turquoise blue were five favourite shades of yarn. Purl structure was mostly used for sock and armbands knitting, plain structure for knitted coats, rib structure for socks and vests, and sometimes warp knitted fabric for scarves. The average fineness of the yarn for making scarves was 208 tex, and for massive coats as much as 3513 tex. By far the most popular way of repeating an ornament is translation, where the ornament remains unchanged, i.e. p1., another well used is translation and mirror reflection, i.e. p1m1.

The results obtained from the analysis of fabric contribute not only to the understanding of the originality of character of Croatian traditional knitwear but also allow the production of copies or souvenir production

Sustainability issues have gained importance both in general and specifically in the textile and clothing sector. In the knitting sector, increasingly close contacts between textile and clothing engineers with textile and nontextile professionals, textile and clothing designers, fibre and yarn suppliers, knitting machine manufacturers, and direct users of knitted textiles and clothing, as well as ICT experts, are dictating strategies for innovative clothing and non-clothing production.

These strategies include measures and define steps for the gradual transition to a circular economy. Sustainability is not just a new approach or a trend that is fashionable right now, but a compelling concept for the survival of companies in the future. At recent trade shows, both machine builders and knitted products manufacturers have demonstrated the adaptation of materials, equipment, and production to sustainable concepts, along with smart manufacturing, cloud computing, cyber production control and robotisation of knitting processes. As an example, the CLEANTEX project is presented, which aims to improve the sustainability of the modern textile sector.

It promotes the adoption of circular economy and eco-design concepts to improve the skills of textile engineering students and workers in the sector. During the recent summer school, students participated in a hackathon whose goal was to integrate circular economy and eco-design strategies into the new production process of a virtual knitwear company.

In this study, some dimensional and thermal comfort properties, i.e. thermal resistance, water vapor permeability, and air permeability properties of interlock fabrics knitted from different cross-section shaped polyester fibers were investigated. Four different polyester yarns of fiber cross-section shapes (hollow, round, triangular, and W-shape) were used to produce the samples. From the results, it was found that the triangular and W-type fibers had higher fabric density values due to the denser and closer fiber settlement.

The highest bursting strength value belonged to the sample knitted from hollow-round yarn which had also the highest yarn-breaking load value. The samples knitted from both round cross-section polyester yarns had significantly higher air permeability and thermal resistance values than the other samples due to the lower fabric density values of these fabrics. On the other hand, the water vapor permeability values of the fabrics from triangular and W-type fibers were slightly higher than the others because of lower thicknesses.

The setting of circular knitting machines requires proper arrangement of the knitting needles and all cams. Both together determine the knitting pattern. For the pattern designer the opposite way of thinking is more efficient – he or she has to select the needles types which are required and can place the structural elements  - loops, tuck, transfer, pass on selected needles in each row and the cams for these selections are resulting on the element selection.

These both ways if thinking are integrated into the new CAD software from company TexMind “Circular Weft Knitting Editor”. The user can select one of the ways of thinking and the knitting logic is implemented and the resulting elements are set automatically. In this way any errors in the needle, cam or element selection are eliminated. The final result is a well formatted report, which can be exported as PDF, SVG or WMF vector formats for the production. Representation of the loops in 3D is under development.

Currently, only a very small percentage of textiles are recycled; the majority are incinerated or disposed of in landfills. A major problem is fibre blends with synthetic content. Due to the advancing climate change, responsible use of existing resources is becoming more important than ever before.

The process of rethinking begins in product development with the selection of raw materials.

In the project "CannaReWool" (EFRE-0802000), German hemp and pure recycled wool are spun together and knitted into fabrics. The aim of the project is to produce knitted fabrics that are closed loop recyclable due to their novel combination of materials. Both materials were selected for their low impact on the environment. One focus of the investigation is on different blending ratios in order to be able to measure the influence of the raw materials. In addition, the entire process from spinning preparation to spinning and knitting is evaluated in terms of its impact on the resulting product. The knitted fabrics are produced using the innovative Doubleface technology.

The project is funded by the European Regional Development Fund (ERDF, Funding reference: EFRE-0802000).

All current interim results of the project will be presented in the conference.

Tapes and tubes are produced from the technical fibres or yarns as yard goods on flat knitting machines, circular knitting machines, braiding machines and ribbon weaving machines. Knitted products are particularly flexible and drapeable due to the stitch structure.

Profiled hoses with an inserted core are, for example, used as a thermal seal in blast furnaces.

These seals are produced in several operations.

1. Production of the knitted hoses

2. Insertion of the core component

3. Stitching over the entire length to fix the core component and to create the profile adapted to the application.

This method is not only time-consuming but also cost-intensive. So far, there is no possibility to automate this process as a one-step operation, as the production of profile hoses can only be realised on flat knitting machines and there is no continuous feeding device of endless cores for flat knitting machines.

The technical evaluation of state-of the-art flat knitting machines on the market for the processing of technical yarns, the production processes of current technical tubular, and ribbon knitted fabrics, indicates the following problems:

1. Uneconomical production of profiled hoses with inserted core

2. Connected cam boxes

3. Moving holding-down sinkers

4. Low patterning flexibility

5. Increased fibre dust generation

6. Drastically shortened lifetime of needles and needle beds

This paper is highlighting on the technical challenges for the Wing shot insertion in various aspects like:

• Preparation from the endless core inlay
• Connected cam boxes
• Shortened needle lifetime
• Flexibility is lay-out and design from the profile

Charles Ross, a leading figure in the outdoor clothing sector recently stated “In the long term, the environment and the economy are the same. If it is un-environmental, it is un-economic’’ (Ross, 2022). Integration of responsible apparel design and manufacturing processes for any company that occupies space within the textile and fashion industry is now a stark reality, with the proposed launch of an outdoor athleisure brand named Nephin Peaks as part of the cross-collaborative project ‘FUSION ‘(James Arthur Ltd, Intertrade Ireland and Belfast School of Art) the only correct approach could be one centred around such a statement, through the application of a ‘responsible’ design practice.

As part of FUSION, James Arthur Ltd provided an opportunity to do this and with the project lead’s background based in knitted textile design a predominantly jersey knit collection was agreed. This then led to such questions as, ‘Who were the would-be competitors and what was their fabric range’, ‘What was available in terms of responsible innovative knit constructed materials at low MOQ’s?’ ‘What level and type of material performance would be the focus?’

Some of the project leads previous research had been concentrated on developing degradable performance knitted textiles, so knowledge of leading industry yarn suppliers was present but little investigation had been done into what fabric mills were focused on such innovations. As a self-funded start-up label, the balance between the social and environmentally holistic design approach wanted and creating apparel with a reasonable but fair price point to reflect this is challenging, especially with the current economic forecast and the continued tightening of the consumer purse string.

The need for in-depth market material and product research is key for differentiation in terms of product USP (unique selling point), to be a realistic competitor alongside leading industry names such as the US’s Patagonia and the UK’s Finisterre, both with extensive jersey ranges. With continuous new data being released around fibre, additives and manufacturing processes in relation to environmental impact, for example the repositioning of The Higg Index to incorporate post gate use, this project provided the space to review best sourcing and design practice. This required a mixed methodology of quantitative and qualitative research, investigating current market trends within the fibre, material, outdoor and athleisure sectors, interviewing experts within sustainability and reviewing the most up to date research.

The main findings from the research were although ‘responsible’ performance knitted textiles are one of the fastest growing areas within the fabric supply sector the move away from fibre blends using virgin non-renewable synthetics, or new gen synthetics without a closed loop production (effluent processing) is a slow process. Thus the choice mainly fell between provenance or performance, with a lack of fibre certification from many mills highlighting the issue of greenwashing within marketing. Mills such as Pontetorto located in Prato, Italy provided the most comprehensive ranges of innovative knits structures using responsible fibres such as Tencel at low MOQ’s.

Knitting has a long tradition in Slovenia. It developed from a domestic economic activity through specialized craftsmanship to a well-developed industrial sector. After the First World War, the knitting industry expanded quite rapidly and reached the position of the second most important industry in the country. The towns of Ljubljana, Kranj in the north and Maribor in the north-east became the well-known textile centers. There the industry was supported by renowned educational institutions with a long tradition.

It led to accelerated progress, investments and the development of new products, especially in the clothing and knitting sectors. After stagnation in the 1980s and market contraction as a result of the country's independence in 1991, the crisis hit many companies that were not able to adapt immediately to new circumstances. Privatization and structural change have had an additional impact on the break-up of the local knitting industry. Not all government measures to promote the development and maintenance of employment in this sector have been successful. In contrast to the mergers in the heyday, the large companies were divided into smaller and more flexible units.

Today, the knitting industry in Slovenia is mainly represented by small and a few medium-sized companies producing underwear, sports and leisure wear, technical products and unique knitwear and knitted accessories. The paper presents an overview of the past and contemporary Slovenian knitting tradition, with a focus on design and including both industrial and (handi)craft production.

This paper discusses an 18 month In funded IntertradeIreland Innovation Boost collaboration with Donegal Yarns and Ulster University. The main focus of the research was to identify and investigate potential new products and processes for the company. This included both the development of new yarns from blends and mixtures of natural sustainable materials and also explore the possibility of developing technical textiles for a number of industrial and domestic uses. Irish wool is seen as a category 3 waste alongside animal carcasses, and in recent years has presented a disposal issue, with Brexit and Covid challenges. As a result, the research project aimed to create a yarn from a blend of Irish wool and hemp fibres. The comingling of hemp and wool was specifically selected due to an increasingly growing interest in farming hemp for its versatility in medical, Industrial, and nutritive products but also because of its environmental benefits and carbon sequestration. This paper discusses the results of the blending of natural fibres together including Irish wool and hemp, and also the blending of polymer and Irish wool. The focus on testing waste fibres into viable higher value products for a range of possible end users.
