TEXTURISING, A KEY FACTOR IN SYNTHETIC FIBRE MANUFACTURE

by Neus Jorda

R+D PROJECT

Colour variations during fibre processing is a worrying problem. AITEX’s DTYarns project is researching ways of optimising the processing conditions which will in turn lead to better management of the resources used.  

By developing the project the aim is to undertake a comparative study between the two most commonly-used procedures for yarn texturising: false-twist texturising and TASLAN air texturising. A parallel study will also be performed of “Bulked Continuous Filament” or BCF, using the same methodology.

This will take the form of an in-depth study of the internal structure of the polymer before and after texturising to determine the degree of crystallinity it possesses, and how colour variation is influenced by post processing with the aim of minimising the effect. Seven specific objectives have been identified to ensure the successful outcome of the project:

1. Research into the internal behaviour of the polymer in relation to the processing parameters
2. Optimise the false-twist texturising parameters
3. Optimise the TASLAN texturisation parameters
4. Compare the false-twist and TASLAN texturising processes
5. Eliminate water consumption from the dyeing process. Optimise the bulk-dyeing process
6. Reduce energy consumption
7. Optimise the BCF (Bulked Continuous Filament) processing parameters

The project is funded by the Conselleria d’Economia Sostenible, Sectors Productius, Comerç i Treball of the Generalitat Valenciana through IVACE, and is co-funded with the EU’s ERDF within the ERDF Operational Programme of the Comunitat Valenciana 2014-2020. FILE: IMDEEA/2017/67
