Abstract
Thermal processing properties are a key factor in the industrial processing industry. The obtaining of a PET-based hybrid composite multifilament with textile properties (yarns) is presented. The system is composed by ceramic silicon carbide (SiC) nanoparticles and a dispersing agent included in a PET matrix. With the objective to produce a suitable nanocomposite, the study is divided in three parts: (i) evaluation by non-isothermal crystallization of three different dispersing agents (two of them based on esters of montanic acids and, the other on an amide wax) to achieve an homogeneous nanocomposite; (ii) study of the influence of the concentrations of SiC and of the more suitable dispersing agent on the thermal properties of the PET-hybrid composite; and (iii) the obtaining of a PET-hybrid multifilament with textile properties together with its characterization by Gel Permeation Chromatography (GPC), Differential Scanning Calorimetry (DSC) and mechanical properties.
