The Stretching Property of Amilan Yarn, after Melt Spinning

Effect of Melt Spinning Variables on the Structural Changes of Recycled and Bottle Grade Filament Yarn PET

YARN: Spinning-in-Progress

YARN (Yet Another RussNet), a project started in 2013, aims at creating a large open WordNet-like thesaurus for Russian by means of crowdsourcing. The first stage of the project was to create noun synsets. Currently, the resource comprises 100K+ word entries and 46K+ synsets. More than 200 people have taken part in assembling synsets throughout the project. The paper describes the linguistic, t...

Investigation of the Tearing Performance of Fabrics with Various Constructions, Woven from Different Yarn Spinning Systems

A Study on Spinning Limits and Yarn Properties with Progressive Change in Yarn Count in Friction Spinning

The spinning limit for three different fibres (cotton, viscose rayon and polyester) on a Dref-3 friction spinning machine has been investigated. The change in yarn properties with progressive change in count has also been reported. The count range has been seen to be dependent on fibre type. As one progresses from very coarse to fine counts, the yarn tensile property remain fairly unaltered for...

Optimal Control of Melt Spinning Processes

An optimal control problem for a mathematical model of a melt spinning process is considered. Newtonian and non–Newtonian models are used to describe the rheology of the polymeric material, the fiber is made of. The extrusion velocity of the polymer at the spinneret as well as the velocity and temperature of the quench air serve as control variables. A constrained optimization problem is derive...
