1,3-propanediol is used as a monomer in the production of some polymers e.g. polytrimethylene terephthalate used in the production of carpets and textile fibers and in the thermoplastics engineering. However, the traditional chemical synthesis is expensive, generates some toxic intermediates and requires a reduction step under high hydrogen pressure. Biological production of 1,3-propanediol cou...

This paper studies the relationship between crimp curvatures and elastic strains of two series of PTT (Polytrimethylene terephthalate)/ PET (Polyethylene terephthalate) self-crimping fibers produced with two different spinnerets which merge PTT and PET fluids at different points. The crimp curvature is estimated based on fiber crosssectional parameters and the polymer properties. The elastic st...

The textile industry has lately started exploring the possibility of bio-sourcing for synthetics, notably polyester fiber, in effort to break from proven fossil-fuel dependency and decrease environmental impacts. Traditionally made out fossil-based polyethylene terephthalate polymer, can be functionally substituted with three bio-based alternatives: bio-polyester, polytrimethylene terephthalate...

Recently, wearable flexible sensors for intelligent sports monitoring have attracted much attention. In this work, we designed the polyvinyl alcohol (PVA)/polytrimethylene terephthalate (PTT)/LiCl hydrogel to act as conductive of triboelectric nanogenerator (PPL-TENG). Significantly, PPL-TENG device has high transparency and stretchability, demonstrating excellent ability in complex mechanical ...

It is common to use open-end rotor yarn in the production of denim fabric, which preferred by people all ages and social status due its durability comfort. Recently, demand for stretch fabrics that can take body's shape elastic fibers structure has been increasing. However, producing elastane-containing yarns spinning system not as practical ring spinning. For this reason, study aimed staple Su...
