Cultura e innovación en el sector del textil y la confección. Transición socio-técnica, diseño y experimentación cultural
2021
Esta tesis doctoral consiste en un proceso de construcción teórica en dos fases metodológicas deestudio de caso, sobre el papel de la cultura en la transición del sector del textil y la confección (T&C). Se orientapor sendas preguntas sobre cómo la cultura, a nivel tanto conceptual como metodológico, puede ser parte integralde la transformación de los profundos conflictos de sostenibilidad ambiental y social de este sector industrial.En concreto, provee un marco de análisis sobre la manera en que la cultural se inserta en los procesos detransición socio-técnica y un marco metodológico basado en el diseño de experimentos culturales que, a nivel local,buscan generar cambios sostenibles y radi…
Heterogeneity of muscle activity during sedentary behavior
2016
Replacing sitting by standing has been hypothesized to reduce the health risks of sitting, based on the assumption that muscles are passive during sitting and active during standing. Interventions have been more effective in overweight (OW) than in normal weight (NW) individuals, but subjects’ muscle activities have not been quantified. This study compared quadriceps and hamstring muscle electromyographic (EMG) activity between 57 NW (body mass index (BMI) 22.5 ± 1.5 kg/m2, female n = 36) and 27 OW (BMI 28.4 ± 2.9 kg/m2, female n = 8) subjects during non-fatiguing standing (15 s, EMGstanding) and sitting (30 min). EMG amplitude was normalized to EMG measured during maximal isometric knee ex…
A New Perspective on the Textile and Apparel Industry in the Digital Transformation Era
2022
The textile and apparel (fashion) industry has been influenced by developments in societal socio-cultural and economic structures. Due to a change in people’s preferences from economic functionality to supra-functionality beyond economic value, the fashion industry is at the forefront of digitalization. The growing digitalization in the fashion industry corresponds to digital fashion, which can satisfy the rapid shift in consumers’ preferences. This paper explores the evolving con-cept of innovations in digital fashion in the textile and apparel industry. Specifically, it centers on the evaluation of Amazon’s digital fashion initiatives, which have made the platform the Un…
An antique lead coffin discovered in Évreux (Eure): a multidisciplinary study
2013
The Roman cemetery of le Clos au Duc in Évreux (Eure) lasted from the 1st to the 4th c. AD. The most common funerary practice in the 1st c. AD was cremation. From the beginning of the 2nd c. AD this rapidly gave place to inhumation burials. By the end of the 3rd c. lead coffins could be found in burials, but it remained a minority practice reserved for an elite. The 2010 excavation in Évreux allowed the recovery of an example of these. It was incomplete, but the good preservation of its remains made a multidisciplinary study possible. Apart from the bones of a young woman, the lead coffin contained coins, textile, fur, calcite (CaCO3) and insects. These results make it possible to retrace t…
Causes of Work Related Musculoskeletal Disorders in the Textile Industry
2020
In Latvia textile industry workers suffer from work-related muscular skeletal disorders (WRMSD). The aim of the research is to study the causes of WRMSDs for the tailor’s profession in a medium- sized enterprise. This research involved 120 tailors. Modified Standardized Nordic questionnaire, Borg Scale of Perceived Exertion, Key indicator method was used for analysis of physical workload during manual handling operations. Main survey results show that tailors suffer from pain in shoulders, wrists and fingers, have repetitive arm movements in sitting compulsory work position. Accordingly to Key indicator method tailors refer to hard work level but Borg scale results indicates the load betwee…
Do Running and Strength Exercises Reduce Daily Muscle Inactivity Time?
2016
Understanding how a specific exercise changes daily activity patterns is important when designing physical activity interventions. We examined the effects of strength and interval running exercise sessions on daily activity patterns using recordings of quadriceps and hamstring muscle electromyographic (EMG) activity and inactivity. Five male and five female subjects taking part in a 10-week training programme containing both strength and interval running training sessions were measured for daily muscle EMG activities during three days: on a strength day, an interval running day, and a day without exercise. EMG was measured using textile electrodes embedded into sport shorts that were worn 9…
Durability of a 3D woven composite assisted by finite element multi-scale modelling
2012
International audience; The textile composite studied is a 3D woven composite. A unit cell is defined by using microscopic examinations of the microstructure. A multiscale approach assisted by the finite element method is performed in order to estimate the effective properties of the composite and then to access to local stress field. This approach allows the determination of the kind of load to which warp yarns are subjected. Moreover, detailed analysis of damaged model using different configurations of broken yarns are treated. The evolution of the stress concentration coefficient highlight the load transfers due to consecutive yarn breaks.

Impact of Different Washing Conditions on the Release of Ag Species from Textiles
2016
The paper investigates the Ag release from textiles (socks available in shops, cotton and viscose filled with Ag nanoparticles–AgNPs) into a washing solution under different conditions. The released Ag amount depended on various factors, such as test media (chemical composition, temperature and water volume), metal contents, and textile impregnation conditions. Furthermore, it turned out that the textile type and colour were the main parameters affecting the Ag release. The Ag concentration in the washing solution ranged between 0.015 μg/l and 4.44 μg/l (socks) and between 0.61 μg/l and 103 μg/l (AgNPs–filled cotton). The total Ag percentage released into water during one washing varied con…
