The rapid increase in consumption has led to the decrease and even extinction of natural resources on earth. The textile industry also has an important place in terms of consumption. The transition to more sustainable biodegradable products instead of established fossil-based materials has increased rapidly due to textile manufacturers and related industries, legal regulations, social responsibility commitments and increasing ecological awareness of customers. Developing new environmentally friendly, biodegradable material groups with new technologies or by modifying existing technologies has been the main goal of many researchers. In this context, we aimed to develop denim fabric that is effective against strong hospital bacteria by using the yarn containing biopolymer chitosan as a weft in denim production. Chitosan finds wide application in the textile industry due to its biodegradability, antibacterial activity and many more functionalities. Chitosan is used in biomedical textile applications in the textile industry, either as a wound healing, hemostatic (blood stopper), antibacterial, antifungal, either alone or modified to various derivatives or combined with other materials. In this context, instead of using chitosan as a coating material in our studies, chitosan-containing yarn was used in the production of denim fabric in order to distribute the chitosan more homogeneously and to increase the washing resistance. As a result, it was determined that the denim fabric developed by using chitosan-based yarn in weft in denim production reduces hospital bacteria (MRSA-Methicillin resistant staphylococcus aureus) by > 99%.

Today, sustainable textile dyeing technologies are being researched with a purpose of developing ecofriendly dyes that are cost effective and resource efficient. Natural Earth Pigments also known as native earth pigments, earth colours, earth ochres, iron oxide pigments etc. come from naturally occurring minerals, typically iron oxide or manganese oxide. Terra dye is a sustainable and environment friendly dye which has been derived from pigmented earth and without the use of harsh toxic chemicals. It is 100% natural, obtained from the extraction of minerals. The study investigates the application of ‘Terra dye’ on cotton knitted fabrics. 100% Cotton Jersey and 100% Cotton Fleece fabrics were used. The terra dyed fabrics were tested for their properties of colour uptake, bleeding, rubbing fastness, resistance to light and washing fastness. The effect of different fixing agents was investigated. The results of the lab trials and testing, conclude that Terra dye has good prospects of being used in dyeing.

Textile-based strain sensors are a potential platform used in wearable devices for sensing and. 8 sensors containing monitoring the human body. These sensors not only have all the conventional sensors benefits but also, they are low-cost, flexible, light-weight, and easily adopted with three-dimensional shape of the body. Moreover, recent research has shown they are the best candidates for monitoring human’s body motion. In this study, the effect of tensile fatigue cyclic loads on performance and sensitivity of textilebased strain sensors was investigated polyester/stainless steel staple fiber blend yarn as a conductive part with different structures were produced. The sensors varied in weft and warp density, percentage of stainless steel in conductive yarn, the number of conductive yarns, and weave pattern. The sensors were subjected to 500 cyclic loads operations and their tensile properties and sensitivity were investigated and compared before and after applying tensile fatigue cyclic loads. The results showed the textile-based strain sensors containing less percentage of stainless-steel fiber, lower number of conductive yarns, twill weave pattern and lower density in warp and weft direction have shown better performance after tensile fatigue cyclic loads.

The growing relevance of sustainable materials has increased the importance of hemp-containing products obtained from natural fibers. When the raw materials used in the garment industry are examined, it is observed that the market share of hemp-containing fibers is low in percentage. Researching the production techniques and methods of fabrics to be obtained from hemp fiber and adapting them to the use of clothing will contribute significantly to the development of the hemp product range. It is aimed that these fabrics to be developed will pass tests in accordance with end-consumer standards. In this study, structural and performance properties of hemp fiber were examined and alternatives were produced instead of conventional methods for a sustainable world. In line with the sustainability strategy, there are advantages of hemp fibers in terms of water consumption, environmental impact compared to cotton fiber. Within the scope, studies were carried out to develop single jersey knitted fabrics by hemp- containing at different compositions such as 70 % cotton/ 30 %hemp, 80 % cotton/ 20 %hemp and 90 % cotton/ 10 %hemp, %100 cotton fabric having the similar structural properties was taken as a control sample. As a result, prototype tests were performed considering the structural and performance properties of the developed fabrics.

The main purpose of the article is to present the new possibilities of producing natural fiber composite reinforcement. In this case, a computer embroidery machine by ZSK type JCZA 0109-550 was used. A technical embroidery with a stitch length of 2 mm was made on the machine. The embroidery was made of flax roving with a linear density of 400 tex. The woven fabric was made of the same flax roving as the embroidery, with a surface mass of 400 g/m2. Composites were then produced from the technical embroidery and woven fabric using the infusion method with epoxy resin. The individual configurations differed from each other in the orientation of the roving in the embroidery samples. Samples for tensile strength and tensile elongation tests consisted of 4 layers, while samples for the DCB test consisted of 6 layers, with the addition of a separating foil between the 3rd and 4th layer. Composites were then subjected to strength tests - tensile strength, tensile elongation and DCB test (Double Cantilever Beam test), on the INSTRON machine. During the action of force along the direction of the fibers, composites containing technical embroidery as reinforcement were characterized by higher strength than composites containing woven fabric as reinforcement. Additionally, embroidery is a barrier to the formation of interlayer cracks. Technical embroidery is made on the basis of Tailored Fiber Placement (TFP) technology. This technology allows optimizing the mechanical values of the composite reinforcement.

The aim of this project is to create novel elastic knitted materials with improved comfort for medical products. In this context, warp knitted structures were produced using different weft threads laying in. The elastic warp knitted fabric produced with transverse weft threads for the whole width was used as a reference sample. It is widely used in medical products. Laying in weft threads with a partial set according to a certain repeat allows us to get structures in which there is no connection in adjacent wales in certain places. This leads to the formation of through holes in the structure. As a result of increased permeability, comfort properties are improving. The structure, functional and comfort properties of developed and reference elastic warp knitted fabrics were investigated. It was found that novel elastic fabrics have higher values of comfort indicators and provide the necessary functional properties.

The Jacquard shed opening system, which makes it possible to open the shed by controlling the warp threads in groups and obtain different designs and shapes, differs from other shed opening systems in that each group of warp threads and each of them can be controlled as needed. The various warp movements, which are limited by the number of frames in other shedding systems, are limited by the number of sinkers in the Jacquard system. Since all known Jacquard shedding systems are designed for operation with single shed weaving machines, they cannot be used for shedding on multiple weaving machines. In this study, a new electronically controlled jacquard machine for multiple shed weaving machines was developed, which eliminates this problem and enables the opening of the weaving compartments by controlling the warp threads individually in multiple shed weaving machines, thus allowing the weaving of all known jacquard fabric patterns. The technological and kinematic schemes of the jacquard machine were prepared taking into account the type of fabric to be produced, the operating principles of the weft insertion and shedding mechanisms to be used in the machine to be developed, and the expectations for improving the technical and economic indicators of the machine. The electronically controlled pattern reading system, which consists of modules in the machine, converts the electronic data into mechanical data to ensure shedding. In the cam shedding mechanism, which transmits motion to the knives in the form of a stepped shaft in the multiple weaving machine, the warp threads are placed on the knives so that they can move vertically. They are controlled by specially structured sinkers which, in contact with the blades, move from the lower to the upper state with the help of the blades and from the upper to the lower state with the help of springs. When the warp threads are to remain in the upper position according to the pattern, the sinkers are interlocked by electromagnets to form an undulating nozzle corresponding to the fabric pattern. By arranging the interlocking projections along the sinker, it is possible to match the density of the sinker to the density of the warp threads. Since the machine allows weaving of all known jacquard fabrics, the problem of not being able to produce weaves other than the rag foot weave, which is considered one of the major drawbacks of multiple shed weaving machines, has been solved.

Static image analysis is known as a versatile method, which is in use for characterisation i.e. of fibres, nonwovens, textile recyclates etc. Due to incomplete standardization (esp. in the area of sample preparation) the usage is actually limited. Within the project StaPAFaB two research institutes are engaged to compile a reference manual listing typical classes of materials and optimised methods of sample preparation for each of them. This will be combined with recommendations for reasonable parameters in image acquisition / processing and possible limitations for each type of material. Aim is to enable reproducible and consistent analyses on an inter-laboratory level as well as to reduce the demand of time for the analyses. This article focuses on typical classes of textile materials and adapted methods to enable their quick and reliable sample preparation.

Within the project StaPAFaB two research institutes are engaged to compile a reference manual listing typical classes of materials and optimised methods of sample preparation for each of them. This will be combined with recommendations for reasonable parameters in image acquisition / processing and possible limitations for each type of material.

In this study, a technical double rapier weaving loom was used for the weaving of spacer/distance fabrics with a polyester multifilament based ground warp, binding yarns and with polyester and basalt weft yarns. The spacing of the distance fabrics was achieved by using lancets. Four different bindings were developed and three different lancet heights have been used for the spacing. Thus developed spacer/distance fabrics showed uniform spacing between layers with a total thickness from 11.1 mm to 18.5 mm and were characterized according to their compressive resistance and energy absorption properties.
