Cohort studies in three American asbestos factories were undertaken to investigate the effect of fibre type and manufacturing process on lung cancer, mesothelioma, and asbestosis. Reports have been published on a chrysotile textile plant in South Carolina and a mainly textile plant in Pennsylvania, which also used amphiboles. In the third plant in Connecticut friction products and packings were...
• The first aircraft structural composite components were reinforced with flax in 1940. Flax fibres used adapted technologies (preg, untwisted fibres…). potential to reinforce polymers was already demonstrated Over the past 80 years, varieties and fibre yields have changed significantly. However, geometry mechanical properties of remained stable. last years seen significant changes industrial t...
1.1 Economical, social, environmental, and industrial contexts A significant added value of textiles is sensory in nature. During garment handling in a shop, the customer engages a selection process that involves touching and trying on clothing. A multifaceted multi-sensory, emotional and psychological experience occurs. A decision is made and motivations are based on anticipated reality of pre...
In the mid-twentieth century, natural fibre shortages spurred research into regenerated protein fibres, including wool keratin. Although these materials were soon displaced by outperforming synthetic today’s global shifts towards an eco-friendlier, more environmentally aware, sustainable fashion industry have increased interest such materials. This paper discusses theory behind chemically recyc...
High-quality cotton fibre equates to a more comfortable textile. Fibre length is an important index of fibre quality. Hydrogen peroxide (H2O2) acts as a signalling molecule in the regulation of fibre elongation. Results from in vitro ovule culture suggest that the alteration of fibre cell H2O2 levels affects fibre development. Ascorbate peroxidase (APX) is an important reactive oxygen species (...
When Chinese archaeologists opened an unknown vault under the collapsed pagoda of Famen Temple near Xian (Shaanxi Province, NW China) in 1987, they found a vast amount of valuable silk textiles. The degraded textiles were part of a treasure comprising hundreds of artifacts deposited by Tang dynasty (ad 618–907) emperors as a gift to the temple. Run as a bilateral German-Chinese project, the Roe...
Soft tissue injuries represent a substantial and growing social and economic burden. Medical fibres are commonly used to repair these injuries during surgery. Patient's outcomes are, however, not promising with around 40% of surgical repairs failing within the first few months after surgery due to poor tissue regeneration. The application of nanofibrous filaments and yarns as medical fibres and...
This work proposes biodegradable textile-based structures for tissue engineering applications. We describe the use of two polymers, polybutylene succinate (PBS) proposed as a viable multifilamentand silk fibroin (SF), to produce fibre-based finely tuned porous architectures by weft knitting. PBS is here proposed as a viable extruded multifilament fibre to be processed by a textile-based technol...
