Assessment of the fabric's wear by sound measurements on soldier's uniforms

This study focuses on the evaluation of fabrics friction sound using two different approaches (instrumental and sensory) to analyze the influence of fabric wear on friction sounds. For this purpose, four fabrics were selected and have undergone multiple washes (up to 50). A specific device reproducing the human arm motion is used to produce and record the fabric friction sounds. From these recordings, some acoustic parameters like the total noise level can be determined. Meanwhile, a sensory panel dedicated to hearing assessed the friction sounds by several attributes. This paper identifies the significant correlations between acoustic, mechanical and sensory properties

Adaptive bra designs for the individuals with special needs

Nowadays the numbers of disabled and elderly people is increasing, and the development of adaptive clothing for these people is in demand. The purpose of this study is to add features in bra design, to make it "Easy on, Easy off", to encourage the hemiplegic females to begin to dress themselves and to make dressing easier and more protective for them. This adaptive bra design will offer benefits to the wearer that include independence, conformity to culture, concealment of the disability, comfort, psychological contentment, safety, and durability. Our adaptive bra will promote harmony between functionality and aesthetics. Our e-bra enables continuous, real-time monitoring to identify any pathophysiological changes by monitoring blood pressure, body temperature, respiratory rate, oxygen consumption, some neural activity

A Study of the Consumption of Sewing Threads for Women’s Underwear: Bras and Panties

The article evaluates the amount of the consumed sewing thread for women’s underwear (underwear bras and panties). Based on the obtained fi ndings, it was concluded that sewing thread amount depends enormously on the studied infl uential parameters. The present paper reports a contribution that allows industries and researchers to decrease the consumed amounts of sewing thread in case of women’s underwear and panties The study takes into account the different stitch structures and fabric characteristics that are usually used. The effects of infl uential input parameters, such as fabric thickness, number of assembled layers, stitch density, and tension of the thread, are investigated. Useful models have been found and can be used by industries to accuracy predict the thread consumption for women’s underwear and panties to launch the needed thread commands. The developed models use multiregressive method. In this study, the fabrics that have been considered are knitted fabrics because they are those used in women’s underwear. We found that women’s underwear bras consume more sewing threads than panties. Using linear regression method, good relationships (coeffi cients of correlation close to 1) between consumption behaviors and the investigated parameters such as fabric thickness, number of assembled layers, stitch number per centimeter, sizes and tension of threads, were found. Although, the increase of threads tension to sew female underwear decreases the consumed amount of threads, the increase of other studied parameters widely encourages the consumption values, especially for seams based on chain-stitch types
