Silk continues to amaze. This review unravels the most recent progress in silk science, spanning from fundamental insights medical silks. Key advances flow are examined, with specific reference role of metal ions switching a storage spinning state. Orthogonal thermoplastic molding is described, as transfer principles for triggering flow-induced crystallization other non-silk polymers. Other exc...

Most spider threads are on the micrometre and sub-micrometre scale. Yet, there are some spiders that spin true nano-scale fibres such as the cribellate orb spider, Uloborus plumipes. Here, we analyse the highly specialized capture silk-spinning system of this spider and compare it with the silk extrusion systems of the more standard spider dragline threads. The cribellar silk extrusion system c...

−A new method is introduced to build up organic/organic multilayer films composed of cationic poly(allylamine hydrochloride) (PAH) and negatively charged poly(sodium 4-styrenesulfonate) (PSS) by using the spinning process. The adsorption process is governed by both the viscous force induced by fast solvent elimination and the electrostatic interaction between oppositely charged species. On the ...

A common problem in production of core–spun yarns on the Ring spinning frame is the slippage of the staple fibers as sheath fibers relative to the core. This effect is known as ‘strip-back’ or barberpole. This problem may lead to an incomplete core coverage and results in end–breaks in subsequent processing. In order to avoid this problem, in the present work, core spun yarns (acrylic sheath fi...
