Professional career

Kyosev completed a five-year engineering course in Textile Technology at the Technical University of Sofia, Bulgaria. He obtained an M.Sc. in Applied Mathematics and Informatics and a PhD in the area of textile machines in 2002, also at Technical University of Sofia. Between 2006 and 2019 Kyosev was Professor for Textile Materials, Textile Technology and Quality Management at Hochschule Niederrhein - University of Applied Sciences, Mönchengladbach, Germany, with a specialty in braiding and narrow weaving. He is the founder and organizer of the International Week of Narrow and Smart Textiles (2014, [7] 2016, [8] 2020 - postponed because of COVID-19 [9] ), an important interaction between experts, industries and researchers in this area. [10] In 2019, Kaiser moved to Technical University Dresden where he is chair of Development and Assembly of Textile Products. [11] [12]

Works

Applied Mathematics

Kyosev developed algorithms for solving fuzzy linear systems of equations, providing first implementing of the theory of Ketty Peeva.[ ambiguous ] [13] In the book, the algorithms are applied for max-min operations, applied as an inference engine for diagnostics of technical, medical and other systems. Later they extend the algorithms for max-product operations, [14] which tends to provide more closer relations of the variables to the natural processes.[ further explanation needed ]

Textiles

In 2006–2008, Kyosev developed a module for 3D visualization of warp-knitted fabrics, integrated into the industrial software Warp3D, for the company ALC Computertechnik, Aachen. The complexity of the warp knitted structures and the challenges of their modeling are summarized in his 2019 book Topology-Based Modeling of Textile Structures and Their Joint Assemblies, [6] while the construction of the warp knitted fabrics is described in the 2019 book Warp Knitted Fabrics Construction. [15]

4D Body scanning

Since 2021, Kyosev's group has been studying the application of 4D (high speed) 3D body scanning systems for development of functional clothing. [16] [17] He organized the international conference "Clothing-Body-Interaction" in 2021 which received favorable community feedback. [18] The conference was held again in 2023. [19] [20]

<span class="mw-page-title-main">Textile</span> Various fiber-based materials

Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns.

Textile arts are arts and crafts that use plant, animal, or synthetic fibers to construct practical or decorative objects.

<span class="mw-page-title-main">Braid</span> Structure of strands of flexible material

A braid is a complex structure or pattern formed by interlacing three or more strands of flexible material such as textile yarns, wire, or hair. The simplest and most common version is a flat, solid, three-stranded structure. More complex patterns can be constructed from an arbitrary number of strands to create a wider range of structures. The structure is usually long and narrow with each component strand functionally equivalent in zigzagging forward through the overlapping mass of the others. It can be compared with the process of weaving, which usually involves two separate perpendicular groups of strands.

Piqué, or marcella, refers to a weaving style, normally used with cotton yarn, which is characterized by raised parallel cords or geometric designs in the fabric. Piqué fabrics vary from semi-sheer dimity to heavy weight waffle cloth. Twilled cotton and corded cotton are close relatives.

<span class="mw-page-title-main">Terrycloth</span> Absorbent textile with a looped pile

Terrycloth, terry cloth, terry cotton, terry toweling, terry, terry towel, Turkish toweling (formerly), or simply toweling is a fabric woven with many protruding loops of thread which can absorb large amounts of water. It can be manufactured by weaving or knitting. Terrycloth is woven on special looms that have two beams of longitudinal warp through which the filler or weft is fired laterally.

<span class="mw-page-title-main">Warp knitting</span> Manufacturing process

Warp knitting is defined as a loop-forming process in which the yarn is fed into the knitting zone, parallel to the fabric selvage. It forms vertical loops in one course and then moves diagonally to knit the next course. Thus the yarns zigzag from side to side along the length of the fabric. Each stitch in a course is made by many different yarns. Each stitch in one wale is made by several different yarns.

The manufacture of textiles is one of the oldest of human technologies. To make textiles, the first requirement is a source of fiber from which a yarn can be made, primarily by spinning. The yarn is processed by knitting or weaving, which turns yarn into cloth. The machine used for weaving is the loom. For decoration, the process of colouring yarn or the finished material is dyeing. For more information of the various steps, see textile manufacturing.

Three-dimensional composites use fiber preforms constructed from yarns or tows arranged into complex three-dimensional structures. These can be created from a 3D weaving process, a 3D knitting process, a 3D braiding process, or a 3D lay of short fibers. A resin is applied to the 3D preform to create the composite material. Three-dimensional composites are used in highly engineered and highly technical applications in order to achieve complex mechanical properties. Three-dimensional composites are engineered to react to stresses and strains in ways that are not possible with traditional composite materials composed of single direction tows, or 2D woven composites, sandwich composites or stacked laminate materials.

<span class="mw-page-title-main">Textile performance</span> Fitness for purpose of textiles

Textile performance, also known as fitness for purpose, is a textile's capacity to withstand various conditions, environments, and hazards, qualifying it for particular uses. The performance of textile products influences their appearance, comfort, durability, and protection. Different textile applications require a different set of performance parameters. As a result, the specifications determine the level of performance of a textile product. Textile testing certifies the product's conformity to buying specification. It describes product manufactured for non-aesthetic purposes, where fitness for purpose is the primary criterion. Engineering of high-performance fabrics presents a unique set of challenges.

<span class="mw-page-title-main">3D textiles</span> Three-dimensional fibers, yarns and fabrics

3D textiles are three-dimensional structures made with different manufacturing methods such as weaving, knitting, braiding, or nonwoven, or made with alternative technologies. 3D textiles are produced with three planar geometry, opposed to 2D textiles that are made on two planes. The weave in 2D textiles is perpendicular. The yarn is fed along two axis: length (x-axis) and width (y-axis), while 3D textiles also have a perpendicular weave, but they have an extra yarn with an angular feeding (z-axis) which creates thickness. 3D weaves are orthogonal weave structures, multilayer structures, and angle interlocks. 3D textiles have more manufacturing opportunities, various properties, and a broader scope of applications. These textiles have a wide range of applications, but they are most commonly used where performance is the primary criterion, such as technical textiles. Composite materials, manufacturing is one of the significant areas of using 3D textiles.

Compaction (compacting) is a finishing process used to minimize shrinking in textiles. Textile products that are loosely woven or knitted shrink more, whereas tightly knitted and woven products are more stable. The structure of knitted fabrics is competitively loose and flexible. Compaction, like sanforization for woven fabric, is intended to reduce shrinkage in tube and open width Knitted textiles.
