AbstractSpider silk attracts researchers from the most diverse fields, such as material science or medicine. However, still little is known about silk aside from its molecular structure and material strength. Spiders produce many different silks and even join several silk types to one functional unit. In cribellate spiders, a complex multi-fibre system with up to six different silks affects the adherence to the prey. The assembly of these cribellate capture threads influences the mechanical properties as each fibre type absorbs forces specifically. For the interplay of fibres, spinnerets have to move spatially and come into contact with each other at specific points in time. However, spinneret kinematics are not well described though highly sophisticated movements are performed which are in no way inferior to the movements of other flexible appendages. We describe here the kinematics for the spinnerets involved in the cribellate spinning process of the grey house spider, Badumna longinqua, as an example of spinneret kinematics in general. With this information, we set a basis for understanding spinneret kinematics in other spinning processes of spiders and additionally provide inspiration for biomimetic multiple fibre spinning.

The aim and scope of this work included the design and practical implementation of a digital monitoring system for the polyacrylonitrile (PAN) fibre spinning process line used for the creation of different PAN based fibres doped with silver (Ag), polyaniline (PANI), carbon nanotubes (CNT) and 2,3,5-triphenyltetrazolium chloride (TTC). After the collecting and processing of process parameters, including bath temperatures and the rotational speed of the feeding-receiving points, available in the form of digital data, they were compared with the appearance of fibres obtained (their surface structure and cross-section shape) and with the results of the fibre specific strength (WtP). Archiving of speed and temperature measurement data allowed to create a database combining the process parameters with the parameters of the fibres obtained. Online monitoring of the parameters enabled programmable change of the speed and temperature in important parts of the process in order to develop appropriate production profiles.
