Test Methods and Identification of Recycled Polyester
87
methods in the industry to contribute towards recycled polyester. For future developments in recycling, the practitioners must have textile expertise in assessing and
guiding the vision and transition for a circular textile’s economy. The closed-loopsystem seems to be moving towards a circular economy. The apparel recycled products are the future demand turning on the identification technologies and approaches
for material processing from collection to sorting, sorting to processing, and finally
producing a new recyclable product.
Creating a demand for new recycled products is critical. The recycled content can
be determined in weight percent and certified based on eco-friendliness in reuse with
eco-labels. Recycled materials fulfil the following as (1) driven by media scrutiny;
(2) producer and consumer demands; (3) sale and cost; and (4) resource scarcity.
The strategy for the textile industry to survive is “invention and innovation” but
their supply chain is so complex as time-consuming and difficult in the practical
implementation of the schemes and systems. Environmental sustainability has been
promoted among the developers of the life cycle assessment of garments. It is critical
to address the developing efficient recycled content, sale and closed-loop recycling
programs. Despite the competition, hand in hand collaboration can help in progressing the industry.
The development of new methods for the identification of fibers as polyester
based or rPET by the chemical solubility tests and DSC analysis for the melting
temperature has been discussed. Thus, the melting temperature of the fibers usually to
be 250–260 °C. From the FT-IR analysis, the essential active groups can be identified
and compared with the regular fiber. Microscopic analyses are essential to study the
round cross-section of fibers. From the investigation, Aerelle, Quallofil, and Comforel
have only one channel and Hollofil fiber has four channels. Thermal stability can be
studied from the thermogravimetric analyzer. Among others, the determination of the
morphological difference in hollow rPET fibers is the most useful characterization.
