Choreography of silk spinning by webspinners (Insecta: Embioptera) reflects lifestyle and hints at phylogeny [PDF]

open access: yes, 2016
Silk spinning defines the morphologically constrained embiopterans. All individuals spin for protection, including immatures, adult males and the wingless females. Enlarged front tarsi are packed with silk glands and clothed with ejectors.

EXPERIENCES IN THE AIR SPINNING TO MANUFACTURE MEDICAL DEVICES [PDF]

open access: yesAnnals of the University of Oradea: Fascicle of Textiles, Leatherwork, 2015
The work aims to determine, with scientific rigor, differences in key parameters of the yarns produced by conventional ring spinning systems, open-end and air spinning and its interrelation with the main parameters of those products that are intended for

Methodology of Optimum Selection of Material and Semi-Folded Products for Rotors of Open-End Spinning Machine

open access: yesAUTEX Research Journal, 2020
The article presents the methodology of optimal selection of material and the form of semi-product for the rotors of the spindle-less spinning machine. The multicriteria approach was utilized taking into account versatile criteria.

Solitons in a Baby-Skyrme model with invariance under area preserving diffeomorphisms

open access: yes, 1997
We study the properties of soliton solutions in an analog of the Skyrme model in 2+1 dimensions whose Lagrangian contains the Skyrme term and the mass term, but no usual kinetic term. The model admits a symmetry under area preserving diffeomorphisms.

The X-ray Counterpart of the High-B Pulsar PSR J0726-2612

open access: yes, 2011
Middle-aged, cooling neutron stars are observed both as relatively rapidly spinning radio pulsars and as more slowly spinning, strongly magnetized isolated neutron stars (INSs), which stand out by their thermal X-ray spectra.

Understanding Tactile Characteristics of Natural Yarn and Fabric Through Sensory Descriptive Analysis

open access: yesJournal of Natural Fibers
This study investigates the tactile properties of natural yarns and fabrics through sensory descriptive analysis, supported by Principal Component Analysis (PCA) and hierarchical cluster analysis to identify clusters with similar sensory profiles.

Fiber Alignment and Straightening in Opening for Open-End Spinning [PDF]

open access: yesTextile Research Journal, 1993
Sliver separation is an essential operation in open-end spinning. Ideally, the sliver should be separated down to individual fibers, each of which is transported in a fully extended configuration. In reality, however, fiber behavior is far from ideal.

Sustainable hybrid yarns from pineapple leaf and recycled cotton fibers: A green manufacturing approach and quality assessment in open-end spinning

open access: yesGreen Technologies and Sustainability
The increasing demand for sustainable materials in the textile industry has prompted the exploration of agrowaste fibers as alternative raw materials for circular production systems that convert waste into high-value products.

Distinct signatures of spinning PBH domination and evaporation: doubly peaked gravitational waves, dark relics and CMB complementarity

open access: yesJournal of High Energy Physics, 2023
Ultra-low mass primordial black holes (PBH), which may briefly dominate the energy density of the universe but completely evaporate before the big bang nucleosynthesis (BBN), can lead to interesting observable signatures. In our previous work, we studied

Production of Natural Dyed Palm Yarns and Fabrics

open access: yesApplied Environmental Research, 2014
Palm fibre is a waste product from the fruit crushing-extracting process in local communities. This study examined the characteristics of natural dyed palm yarns and fabrics produced from treated palm fibres.
