The fit of the South African National Defence Force male combat trousersLaba, Angelica 01 1900 (has links)
Thesis (M. Tech. (Fashion, Dept. of Visual Arts and Design)--Vaal University of Technology. / This study was contracted by the African Warrior Project of the South African National
Defence Force (SAND F), which focuses on the needs of the future soldier. Fit problems
cause the wearers of these combat trousers physical discomfort during routine physical
training as the trousers restrict movement. The goals of the study were to investigate
problems experienced by the male soldiers regarding the fit of the combat trousers, and
to make recommendations regarding possible fit solutions. The objectives of this study
were to determine the nature of the fit complaints in terms of the wearer characteristics and activities related to aesthetic and functional aspects; to analyse the design of the combat trousers in terms of size, key dimensions, proportion, balance and ease to determine the source of the fit the problems; and to analyse the f1t of the combat trousers against the subjective fit preferences of the wearers, and objective fit opinions of an expert. The target population of the study was the male SANDF members in the target age group of the African Warrior Project, namely 18 to 35 years. The first sample group consisted of 60 SANDF members between the ages of 24 to 45 years. The second sample of 24 subjects was selected from the first sample group, using height and body shape as parameters. The methods included biographic profiling, focus group interviews, one-to-one interviews, motor tests, body and garment measuring, photographs, somatographs and pattern analysis. The findings indicate the possibility of an inadequate garment design in relation to specific wearer characteristics such as ethnicity and body shape. The complicated size designation system used, compounded by the waist as the only key dimension provided, contributed to the distribution of the incorrectly sized combat trousers to the wearers. Analysis of the design indicated that it does not adequately accommodate the body characteristics and fit preferences of the
subjects, to ensure optimum functionality as well as an acceptable aesthetic appearance.
These problems need to be addressed. / ERGOTECH; VUT

Den optimala ridbyxan : konstruktion och gradering för att uppnå en bättre passfrom i alla storlekarNilsson, Linda January 2016 (has links)
Ridbyxor är ett specifikt plagg för ryttare och det ställs därför vissa krav som inte uppkommer på vanliga byxor. Bakgrunden till detta arbete är att företaget bad om ett mönster till en ridbyxa med bra passform genom hela storleksserien. Ett nytt mönster med god grundpassform tas därför fram. Graderingen av byxan gjordes med tanke på hur plagget ska användas samt hur kroppen förändrar sig i de olika storlekarna. Idag tas oftast ingen hänsyn till detta utan plaggen behåller samma proportioner i alla storlekar. För att uppnå ett slutresultat har konstruktionen gjorts i Lectras konfektionsanpassade cad-program Modaris och specifikationerna har gjorts i Illustrator och PISA. En god grundpassform togs fram först genom ett antal avprovningar och mönsterförändringar innan graderingsarbetet tog vid. För att verifiera graderingen gjordes avprovningar på utvalda storlekar. Slutligen kommer grundstorleken att sys upp i fabrik och två ytterligare storlekar att sys upp i Textilhögskolans lokaler. Resultatet visar att relativt många förändringar måste utföras på grundkonstruktionen för att uppnå den passform som önskas. Samt att en gradering som ger en längre grenlängd bak skapar en bättre passform när ryttaren sitter i sadeln. / Breeches are a specific garment for equestrians and therefore it occur certain requirements which are not imposed in regular trousers. The background to this writing is that the company asked for a pair of breeches with good fit throughout the size range. A new pattern with good fit is therefore produced. The grading of the trousers was made in view of how the garment will be used and how the body changes in the various sizes. Today there is often no attention dedicated to this. The result is that the garment retains the same proportions in all sizes. To achieve a result has the patterns been made in Lectras software Modaris and the specifications are made in Illustrator and PISA. A good fit in base size is first achieved thru a number of fittings and pattern changes before the grading work started. To verify the grading fittings of selected sizes was performed. Finally will the base size be sewn at a factory and further two sizes will be sewn at Textilhögskolan. The result shows that relatively many changes must be performed on the basic pattern to achieve the desired fit. And that a grading that gives a longer back rise length is creating a better fit for equestrians when sitting in the saddle.

Hål är inte hållbart : En studie om granskning och produktutveckling av kasserade arbetsbyxorToresson Grip, Linnea, Gatzwiller, Malin January 2020 (has links)
Ett problem inom klädindustrin är att kläder kasseras på grund av att defekter uppstår. Defekter på kläder granskas oftast under produktionen men inte lika ofta efter användning. Denna studie fyller delvis detta gap då karaktär, placering och klassificering av defekter undersöks på kasserade arbetsbyxor. Studien har fokuserat på defekter som klassats som mycket allvarliga, vilket visat att defekterna främst uppstår i form av hål på tyg på framsidan och därefter som nötning vid grenen. Det utvecklades lösningar för de två vanligaste förekommande defekterna som klassificeras som mycket allvarliga. Gällande defekter med hål på framsidan utvecklades en åtgärd i form av ett informationsblad med skötselråd och förslag på ändring av material. För att minska uppkomsten av defekten nötning i grenen skapades olika konstruktionslösningar i form av två olika grenkilar och en justering av grensömmen. För att validera resultatet skapades en enkät som personer inom textilbranschen svarade på. Angående lösningarna för tyghål framkom det av enkätsvaren att endast materialbyte eller det i kombination med informationsblad om skötsel skulle kunna minska uppkomsten av defekten. Av enkäten framkom även att grenkilarna var den lösning som respondenterna ansåg var mest effektiv för att lösa problemet med nötning i grenen. / An existing problem in the clothing industry are garments discarded due to defects. These defects are usually examined in production and not as often after the garments have been worn. This study fills this gap partially by investigating the nature, placement and classification of defects on discarded working trousers. The compiled data showed that the most common critical defects were fabric holes at the front and abrasion at the crotch. After identifying the most common critical defects solutions were developed. Regarding the fabric holes two solutions were created, one was an information sheet on how to handle the garment and another one was a suggestion of change of fabric. Suggested solutions for critical abrasion at the crotch were two different gussets and adjustment of the back rise curve. A survey was conducted to validate and receive comments from the textile industry on the studies results. Regarding the fabric holes, the survey showed that change of fabric as a separate solution or in combination with information about the maintenance of the trousers were the most effective solutions. The survey also showed that gussets were the solutions that was considered the most effective in solving the problem of abrasion at the crotch.

Wheelchair Users Relationship to Clothing : A Study of Incorporating Adaptive Clothing in the Fashion Industry, with an Investigation of Adaptive Trousers and its Functional, Aesthetic and Socio-Psychological QualitiesWallman, Kajsa, Enocson, Sarah January 2023 (has links)
This study investigates the functional and aesthetic needs in adaptive clothes, with emphasis on trousers for wheelchair users. A pair of trousers were provided by Design by Björk to be investigated and distinguish if the desired consumers' needs are met. It’s important to acknowledge the importance of aesthetic and functional attributes in clothing, to not separate standard and adaptive clothing design. In addition, the socio-psychological impact clothes have on wheelchair users was researched, to emphasize the need for an inclusive fashion industry. In the research process for the study it is acknowledged that previous studies encourage further focus on aesthetically pleasing elementents in adaptive clothing. The aim is to increase awareness of how important this aspect is for the consumer in interaction with functionality. A mixed method approach made with convergent parallel design was used to collect data, utilizing surveys and interviews. It is presented that wheelchair users value the functional, aesthetic and comfortable aspects in clothing equally, and that it is important to not compromise with any aspect in the design process. The study confirms that clothing can have a negative impact on the wheelchair users psychological and physical wellbeing, which is highly related to the lack of clothing in the market range that meets the wheelchair users needs. A sample sketch was developed with suggested improvements for a pair of trousers provided by Design by Björk. The result demonstrates that adding adjustable attributes to the trousers can contribute to increased comfort, aesthetic and functional needs of the consumers.

Supressão da vibração induzida por vórtices de cilindros com malha permeável. / Suppression of the vortex-induced vibration of circular cylinders with permeable meshes.Cicolin, Murilo Marangon 06 February 2015 (has links)
O fenômeno de vibração induzida por vórtices (VIV) é particularmente danoso para estruturas submarinas como risers de exploração de petróleo. A maneira mais usual de se atenuarem os efeitos de VIV é instalar um supressor, como por exemplo strakes ou fairings. Dentre esses, foi desenvolvido por All Brow Universal Components um supressor chamado Ventilated Trousers (VT), que consiste em uma malha permeável feita de uma rede flexível e dezenas de bobbins. Através de um estudo experimental, procurou-se investigar os mecanismos hidrodinâmicos pelos quais o supressor V T funciona. Foram construídos três modelos diferentes de supressores: um modelo idêntico ao V T e duas malhas dele derivadas, alterando-se a geometria dos bobbins e a distribuição destes ao redor da malha. Foram realizados ensaios com o modelo xo e ensaios de VIV em um grau de liberdade alterando-se o amortecimento estrutural. Foram medidos deslocamento e forças de sustentação e arrasto. Os resultados mostraram que o supressor do tipo V T reduz as amplitudes de vibração, força de sustentação e arrasto quando comparados com um cilindro oscilando. No entanto, aumenta a força de arrasto quando comparado com o cilindro xo. A geometria da malha mostrou-se de grande importância para a supressão de VIV. Modelos que possuem o disco externo no bobbin impedem o surgimento de folga entre o modelo e o cilindro, além de aumentar o amortecimento hidrodinâmico. Três hipóteses foram levantadas para explicar o funcionamento do supressor V T. A primeira diz que a supressão é provocada pelo aumento do amortecimento hidrodinâmico. Os ensaios mostraram que, de fato, o supressor V T aumenta o amortecimento e, consequentemente, diminui as VIV. No entanto, somente esse efeito não explica toda a supressão obtida. As outras hipóteses, relacionadas à alterações bi e tridimensionais da esteira, foram avaliadas, porém não se pode afirmar que alguma delas seja isoladamente responsável por produzir o mecanismo hidrodinâmico de supressão. / The phenomenon of vortex-induced vibration (VIV) is particularly harmful to submarine structures such as risers used for oil extraction. The most usual way to attenuate the effects of VIV is the installation of suppressors, like strakes or fairings. Among them, All Brow Universal Components developed a VIV suppressor called Ventilated Trousers (VT), which consist of a permeable mesh made of a flexible net and tens of bobbins. Three different models of suppressors based on permeable meshes have been assembled with the objective to understand the hydrodynamic mechanism behind the suppression: one model identical to the VT and two meshes with different bobbin geometries and distribution. Tests were carried out with xed models and models free to oscillate in one degree of freedom varying the structural damping. Displacements, drag and lift forces were measured. Results showed that the VT suppressor reduced vibration amplitudes, lift and drag forces when compared to an oscillating circular cylinder. However, it increased drag force when compared to a fixed circular cylinder. The mesh geometry proved to be important to VIV suppression. Models that had an external disc on the bobbins avoided the appearance of a gap between the model and the cylinder. Three hypotheses were formulated to explain how the VT suppressor works. The first one says that the increase on hydrodynamic damping is responsible for suppression. In fact, tests showed that the VT increased hydrodynamic damping and, consequently, reduced the VIV response. However, this effect alone does not explain the suppression as a whole. The other two hypotheses related to two-dimensional and three-dimensional wake changes were evaluated, but it cannot be stated that any of them, on its own, is responsible for the whole of the suppression mechanism.

Urban kids- Funktionskläder för tuffa miljöerGöth Nilsson, Annika January 2010 (has links)
SammanfattningUrban kids är ytterfunktionskläder för citybarn. Projektet har gått ut på att utveckla funktionskläderför höst och vintersäsong som står i kontrast till outdoor- och sportföretagens estetiska värde. Målgruppen är modeintresserade stadsföräldrar som inte drar sig för att betala det lilla extra för att få en produkt som går i linje med deras livsstil. Syftet med arbetet var att ta fram underlag för att visa att det går att göra tekniskt funktionella ytterfunktionskläder för barn som inte klär sig sportigt.Med hjälp av idégenereringar och en mood board, ett bildkollage för känslan som produkten ska utstråla, har ett koncept arbetats fram under stilnamnet “rockig lekfullhet”. Detta blir ett koncept som är en motsats till det sportiga uttrycket.Genom hela projektets gång har designprocessen varit en vägledning för att nå målet. Detta innebäratt arbetet började med en grundläggande research inom material, miljö och certifieringar, funktionskläders uppbyggnad, konkurrenter, säkerhet och riktlinjer för barnkläder samt användareoch målgrupp. Vidare fortsatte processen med idégenerering och skissning för att ta fram tre koncept som efter utvärdering mot en funktionsanalys skulle resultera i ett slutgiltigt koncept för vidareutveckling.Slutresultatet är en jacka och byxa i skalmodell, vilket gör att plaggen kan användas under en längre period under säsongen. De mest utsatta delarna är försedda med en grövre, mer slitstark textil. Kulörvalet på denna modell är svart. Detta på grund av att den inspirerats av en rockigare attityd, där svart ofta förekommer, men det är inte det enda argumentet. Svart är en mer neutral kulör då plaggen är anpassade för både pojkar och flickor. Det är även en praktisk kulör då smuts inte framträder lika tydligt som om plagget skulle vara i till exempel en ljusare kulör.En annan viktig aspekt som det fokuserats på under projektet är material som går i linje med ett hållbart tankesätt. Fokus har legat på att hitta ett funktionsmaterial som stödjer detta. I researchfasenframkom membranet Eco Storm från den japanska tillverkaren Teijin. Detta material är ett polyestermembran som levereras med en yttertextil av återvunnen polyester.Som slutsats till detta arbete har det framkommit att det går att göra funktionskläder med citykänsla.Detta är inget nytt, speciellt inte inom vuxensegmentet, men skillnaden är att man väljer bort de tekniska funktionsmaterialen för barnkläder. Med Urban kids är detta nu ett alternativ även för barn. / AbstractUrban kids- Functional apparel for rough environmentsUrban kids is functional apparel for city children. The aim for this project is to develop functional clothes for the autumn and the winter season which provides a contrast to the designs presented today by outdoor and sports companies. The target group is fashion oriented city parents that do not hesitate to pay a little extra for a product representing their life style. This project provides a foundation of information to support the idea that it is possible to design technically functional outer wear for children without the sporty look.By using brainstorming and a mood board, a picture collage which gives the essence of the product, the concept “rocky playfulness” was developed. This concept is a contrast to the sporty expression.Throughout the whole project the design process has been the guide to reach the goal. This means that the project started with a primary research on materials, sustainable issues and eco-certificate, competitors, safety and guidelines for children’s wear and requirements from the user and the target group. The process continued by brainstorming and sketching in order to present three concepts. By evaluation using a function analysis one final concept was chosen for further processing.The result is a jacket and a pair of trousers as shell garments in order to use it a longer period of time during the season. The parts of the clothes mostly exposed, are enhanced with stronger, more hardwearing fabric. The choice of colors is black. This is due to the inspiration by a rocky attitude where black is often seen, but it is however not the only reason. Black is a more genderneutral color suitable for both boys and girls. It is also a practical color considering that dirt doesn´t appear as clearly as if the garment had a brighter color.One other important aspect of this project is to use material coherent with recycling and a sustainableway of thinking, focusing on finding functional material which supports this. During the research the material Eco Storm, from the Japanese manufacturer Teijin, was found. It is a polyestermembrane with an outer fabric made of recycled polyester.The conclusion of this project is that it is possible to produce/design functional wear with an urban feeling. This is in itself nothing new, it has been used in adult clothing, but the difference is that the technical function materials are excluded in the children’s wear. With Urban kids this is now also an option for the children.

Optimering av material för höftskyddsbyxor : Med hänsyn till motverkandet av fallskador / Optimisation of materials for hip protection trousers : Considering the prevention of fall injuriesAndersson, Felicia, Eriksson, Amanda January 2024 (has links)
Mellan åren 2008 och 2021 har antalet benskörhetsfrakturer ökat med 30%, främst på grund av att antalet äldre har ökat. Osteoporos (benskörhet) är när benvävnaden blir mindre tät vilket i sin tur resulterar i att skelettet blir allt svagare. En av de vanligaste samt allvarligaste frakturerna till uppkomst av benskörhet sätter sig i höfter, där det varje år sker mellan 15 000– 16 000 frakturer. Höftskyddsbyxor kan beskrivas som ett par specialdesignade underbyxor med skyddande plattor placerade i byxan bilateralt längs höften för att täcka lårbenet. När ett par höftskyddsbyxor används på ett korrekt sätt kan risken minska med upp till 60% för att få en höftfraktur vid fall. Höftskyddsbyxor finns idag på marknaden men ändå väljer en del att inte bära dem. I litteraturen nämns det att vanliga orsaker till att höftskyddsbyxor inte används är att det finns ett missnöje när det gäller estetik, bekvämlighet och elasticitet. Litteraturen nämner även att för att avdöda mikroorganismer är det viktigt att textilen ska kunna tvättas i höga temperaturer. Studiens syfte är att undersöka möjligheten att producera material avsedda för höftskyddsbyxor utan beredningar som är bekväma, elastiska och bibehåller sin kvalitet efter upprepade tvättar i 60°C. Materialen som valts ut för studien omfattar olika kombinationer av cellulosafibrer, regenererade cellulosafibrer samt syntetiska fibrer. Sex tygprover jämfördes med varandra för att se om de mekaniska egenskaperna som identifierats; elasticitet, mekanisk hållfasthet, visuellt utseende och bekvämlighet efter tvätt, kan potentiellt optimeras. Miljöaspekter kring val av fibrer kommer även att diskuteras. Ett företag har lånat ut skyddsplattor till författarna av studien. Studiens resultat ger stöd för att material bestående av syntetiska fibrer presterade högst i materialundersökningen. Resultatet visade att tygprov två hade det högsta totala värdet av alla sex tygprover. Även om tygprovet hade högst värde i flest mätningar så var värdena inte i den utsträckning som hade förväntats. Resultatet påvisade att även om tygprovet fick högst resultat har det sannolikt inte de optimala egenskaperna för ett par höftskyddsbyxor som studien undersökte. Sammantaget kan resultatet av den här studien verka som en förstudie inför framtida studier inom produktutveckling av höftskyddsbyxor. / Between 2008 and 2021, the number of osteoporosis fractures increased by 30%, mainly due to an increase in the number of elderly people. Osteoporosis is when bone tissue becomes less dense, which results in the bones becoming weaker. One of the most common and serious causes of osteoporosis is fractures of the hips, with between 15 000 and 16 000 fractures occurring each year. Hip protectors can be described as a pair of specially designed underwear with protective plates placed in the trousers bilaterally along the hip to cover the femur. When used correctly, a pair of hip protectors can reduce the risk of sustaining a hip fracture in a fall by up to 60%. Hip protectors are currently available on the market, yet some people choose not to wear them. The literature mentions that common reasons for not using hip protectors are dissatisfaction with aesthetics, comfort and elasticity. The literature also mentions that in order to kill microorganisms, it is important that the textile can be washed at high temperatures. The aim of the study is to investigate the possibility of producing textile materials intended for hip protection trousers without preparations that are comfortable, elastic and maintain their quality after repeated washing at 60°C. The materials selected for the study include different combinations of cellulose fibres, regenerated cellulose fibres and synthetic fibres. Six fabric samples were compared to see if the mechanical properties identified; elasticity, mechanical strength, visual appearance and comfort after washing, can potentially be optimised. Environmental aspects of fibre selection will also be discussed. One company has lent protective plates to the authors of the study. The results of the study support that synthetic fibre materials performed best in the material survey. The results showed that fabric sample two had the highest total value of all six fabric samples. Although the fabric sample had the highest value in the most measurements, the values were not to the extent expected. The results showed that although the fabric sample scored highest, it is unlikely to have the optimum properties for a pair of hip protectors that the study investigated. Overall, the results of this study can serve as a preliminary study for future studies in product development of hip protection trousers.
