3D Garment Modelling - Creation of a Virtual Mannequin of the Human Body
(Instytut Biopolimerów i Włókien Chemicznych (IBWCh) , Łódź, Polska, 2014) Cichocka, Agnieszka; Bruniaux, Pascal; Frydrych, Iwona
This work presents the modelling and numerical simulation of mannequins as well as clothes in a 3D virtual environment. The paper explains garment modelling, with the objective of defining the development of a 3D body model that is useful and based on the demand of the garment industry. For this purpose a development strategy should be defined. Many scientists are working on the creative process for virtual garment development to create a garment directly on a 3D model of the human body, also called “ virtual tailoring”.The first strategic issue in this context that we present is that the model must necessarily incorporate the ease garment model associatively. These parameters define the priority concepts that are the draping and proper fit of the garment. The second point is that the transition between the 3D and 2D patterns, known as flattening 3D patterns, must be associative, precise and must take into account the real deformation of the fabric.

Bawełna - systemy i metody oceny
(Wydawnictwo Politechnika Łódzka, 2005) Frydrych, Iwona; Red. nauk. Wydziału: Kowalski, Krzysztof; Włochowicz, Andrzej; Żurek, Witold
The book is destined for the people working with cotton, mostly in the spinning mill, but not only. It can be also very useful for cotton classers, ttaders and so on. In the introduction there are described shortly information about cotton growing and classification, evolution of cotton measurement methods on the example of length parameter and short information about cotton fiber properties, which should be measured for a complex quality assessment. The important parameters are: length, length uniformity, short fiber content, strength and strain, color and impurities like trash, dust, neps, seed coat neps, fineness and maturity. Then there are described modem systems for cotton fiber assessment, like High Volume Instrument (HVD, Advanced Fiber Information System (AFIS), FiberLab system, Quickspin measuring the basie properties and thermodetectors measuring the cotton stickiness. Such systems like HVI or FiberLab measure the cotton parameters by the bundle method; whereas AFIS measures the properties of single fibers and then on this basis the statistical analysis is performed. In chapters 2 - 6 there are information how the systems are built, what are the measurement principles, and what parameters describing the given property are applied. In chapter 7 the Author presents the results of comparative analysis conceming different fiber properties obtained by diff erent measurement methods, like length, short fiber content, fineness and maturity, cotton contamination strength and stickiness. In chapter 8 there are presented information about cotton color measurements; whereas in chapter 9 - the newest trends and directions of evolution in cotton quality evaluation. The last two chapters present how the values of particular cotton parameters can be used in the engineeręd way for blend composing, or to predict some properties of cotton yams, or to assess the correctness of the technological process. The book is a good source of information about equipment used actually in the cotton world industry.
Fancy Threads
(Wydawnictwo Politechniki Łódzkiej, 2019) Grabowska, Katarzyna; Matusiak, Małgorzata (Red.); Frydrych, Iwona; Kozłowski, Ryszard
"The presented research results concerning the structure, properties and production methods of fancy threads do not exhaust the subject, not only because of the dynamic development of new research methods, but also because of the fact that almost every day new types of decorative threads are produced. It depends on the so-called creative fantasy or the designers’ creativity. As has already been stated in the introduction to the present work, fancy threads, besides be- ing the creation of an engineer, are influenced by the designer to a large extent, as far as their properties and structure are concerned. The process of conscious creation of new structures of decorative threads requires engineering knowledge in the field of different spinning or twisting techniques. ..."
Innovations in clothing technology & measurement techniques
(Wydawnictwo Politechniki Łódzkiej, 2012) Bartkowiak, Grażyna; Frydrych, Iwona; Pawłowa, Maria; Gniotek, Krzysztof; Bakar, Mohamed
[...]It is worth to point out that the monograph "Innovations in Clothing Technology and Measurement Techniques" covers almost all the stages of clothing and footwear production starting from the scanning the human body, through the innovative mass customization technology of clothing production, automatic sewing process, clothing textronics solutions, measurement techniques in the clothing industry, finishing on the problems dealt with clothing appearance, fashion and design. It should be mentioned that the clothing industry is very innovative, still developing and a promising sector in the European economy. Also in our country the clothing industry gathers many small and medium enterprises, which have good development perspectives for the future. The monograph consists of four chapters titled as follows: 1. Clothing and Footwear- Construction and Computer Techniques, 2. Smart textiles and Wearable Electronics, 3. Innovations in Measurement Techniques, 4. Fashion and Clothing Design. The chapter titled Clothing and Footwear - Construction and Computer Techniques is the longest one due to the fact that all the problems dealing with the preparation of technological clothing production are very actual now, especially in the European countries. Scanning technology opens the new possibilities for creating the clothing patterns. Using the scanning technique and appropriate software we are able to adjust the clothing to fit better to the human being silhouette. The topics concerned so called "smart textiles" are also very modern now. It is caused by the need of changing the clothing functionality. In addition to cover the human body the clothing can fulfill the other functions like heating, warning the person about any dangerous situations, for example, to warn the fire-fighter, who is involved in the action, that he should leave the dangerous territory. The textronics applied in the clothing can also fulfill the functions important for the health of the user, for example, it can measure the human physiological parameters. The textronics can be also used in the PPE, can enable the specially important data transmission. Shortly speaking this is the content of the next chapter - Smart Textiles and Wearable Electronics. In the chapter Innovations in Measurement Techniques there are described methods used in the clothing physiological comfort measurement (microclimate parameters and water vapor permeability), methods for testing the relaxation properties in the multilayer textile materials, color change of textile materials by a new device DigiEye as well as methods of assessment of special properties important from the safety point of view like a flammability. The chapter Fashion and Clothing Design is devoted for the clothing art designing also with the use of new tools like CAD. The Authors are trying to explore the impact of using the Virtual Reality Technology in fashion communication advertising as a medium, which can be used in fashion photo sessions, fashion shows and fashion shops to improve the acceptance of information on the market. Fashion advertising is a main branch, which focuses on a promotion of the fashion industry. This monographic edition is prepared by many Authors from different countries like: Germany, Slovenia, Ukraine, Russia, Portugal, Lithuania, Belgium, Slovakia, Egypt and Poland. Some of the presentations are prepared in the international cooperation. I would like to thank all the Authors for an effort they undertook to contribute this monograph. Dear Friends, thanks a lot for your very interesting contributions, which make the monograph very consistent and valuable.
Innovations in textile materials & protecting clothing
(Wydawnictwo Politechniki Łódzkiej, 2012) Bartkowiak, Grażyna; Frydrych, Iwona; Pawłowa, Maria; Gniotek, Krzysztof; Bakar, Mohamed
[...] The results of research concerning new types of protective clothing, modeling its characteristics and the phenomena associated with its use, as well as the methodology of testing its protective properties are presented in the chapter ,,Protective clothing and equipment". It presents the results of modeling fabrics for ballistic and stab protective clothing, studies of new basalt textiles designed for protective gloves and of multifunctional high visibility vests. For analysis of the heat transfer from the external environment to the skin, a finite element model of the human skin was presented. This aspect of modeling might be crucial in estimation of heat stress conditions as well as skin bums. Finite-element method was also applied for modeling of ballistic impact on a human torso protected by textile body armor. Comparison between serial and parallel models for estimation of thermal insulation of protective clothing shows that the parallel model is closer to "true" insulation, so the revision of standard presented requirements for that clothing will be needed. The development of new types of protective clothing is closely associated with new, innovative materials. Results concerning, among others, novel materials impregnated with rheological fluids designed for body armor, materials with therapeutic and antibacterial properties are presented in the chapter ,,Innovations of textile materials". It also presents the problems of polymer coatings of synthetic leather for clothing materials, as well as the results of the study concerning the development of technology for new nonwoven materials on the basis of water-soluble polymers. The results of research concerning the effect of chemical processing of textiles on their properties and methods for post-treated ready-made garments are also discussed. Nowadays, in times of sophisticated users' needs and possibilities of application of high-tech solutions in designing products, it is crucial to find an equilibrium among protection, comfort and durability of clothing. The chapter ,,Human comfort in clothing" discusses very important problems associated with the use of clothing and its effect on the user's well-being. The problems of humidity transport, undergarment microclimate and ventilation are discussed and the solutions improving the user's comfort are presented. The methodology of testing fabrics and clothing properties allowing to predict the comfort associated with their use is also described. [...]

Investigation of Naturally Coloured Cotton of Different Origin – Analysis of Fibre Properties
(Instytut Biopolimerów i Włókien Chemicznych (IBWCh) , Łódź, Polska, 2014) Matusiak, Małgorzata; Frydrych, Iwona
Naturally coloured cotton is naturally pigmented fibre that grows in shades of brown and green. Because the colour is present in the fibres, fabrics made of them do not have to be dyed. The elimination of the dyeing process can save up to one half of the cost of preparing textiles and also lowers disposal costs for toxic dye waste dangerous to human health and the environment. In spite of the economic and ecological benefits resulting from the elimination of the dying process, the application of the naturally coloured cotton in the world textile industry is still limited. The low quality of fibres is considered as the most important reason for the limitation of naturally coloured cotton application. The aim of the work presented was to investigate the quality of naturally coloured cotton of different origin as well as to show the potential of the naturally coloured cotton as an excellent raw material for manufacturing ecological textiles of good quality and attractive design.

Strategia marki - analiza rynku odzieży sportowej na jednolitym rynku europejskim
(Wydawnictwo Politechniki Łódzkiej, 2008) Malinowska-Olszowy, Monika; Wysokińska, Zofia; Płowiec, Urszula; Frydrych, Iwona
Produkcja odzieży sportowej jest jedną z sił napędowych rozwoju tekstyliów tzw. inteligentnych, i właśnie z tego powodu może stać się jednym z nowoczesnych produktów eksportowych pozwalających na konkurencyjność na rynkach międzynarodowych. W tym właśnie kontekście szansą na rozwój polskich przedsiębiorstw jest wykorzystanie nowoczesnych technologii i wyrobów specjalnych typu high-tech. Rynek ten jest rynkiem "ewolucyjnym". Bardzo często, prowadząc różnego rodzaju badania nad nowymi włóknami o unikatowych właściwościach, ma się na uwadze ich przyszłe wykorzystanie jako odzieży sportowej. Wiele użytych technologii należy do najbardziej zaawansowanych na rynku. Rynek odzieży sportowej stwarza ogromne możliwości, ale jednocześnie wymaga ciągłego rozwoju, badań, nieustannej pracy nad doskonaleniem produktu oraz prawidłowo stosowanych narzędzi marketingowych. Ważne jest również znalezienie nisz rynkowych i zaistnienie w nich. Celem projektu jest analiza rynku odzieżowego, ze szczególnym uwzględnieniem rynku odzieży sportowej w Polsce w świetle wymagań stawianych przez Jednolity Rynek Europejski. Istotna jest przede wszystkim analiza i ocena strategii marki, stosowanej przez firmy w Polsce, z punktu widzenia ich skuteczności dla przedsiębiorstw oraz możliwości i umiejętności dostosowania działań polskich przedsiębiorców do uwarunkowań i funkcjonowania na rynku międzynarodowym. Analizie poddany został niezwykle wąski segment. Starano się poddać go obserwacji w możliwie wielu aspektach. Dlatego też praca nabrała charakteru interdyscyplinarnego, łącząc w sobie elementy włókiennictwa, ekonomii, zarządzania i marketingu, prawa, jak również elementy analizy statystycznej.
