Case Study

Study on Structure-Property Relationship of Polyester Industrial Yarns

Samui, Barun Kumar, et al. Journal of the Textile Institute, 2013, 104(1), 35-45.

The key structural parameters of four major types of commercial polyester industrial yarn (1000 denier) were studied to establish the relationship between the morphology and properties of these yarns. The four polyester industrial yarns are high modulus low shrinkage (HMLS), high tenacity (HT), low shrinkage (LS) and super low shrinkage (SLS) polyester yarns. The key structure-property relationships of these polyester yarns include:
· The study revealed that "amorphous orientation" is a crucial structural parameter that impacts numerous essential properties of yarn. HMLS yarn exhibits lower amorphous orientation compared to HT yarn, resulting in significantly decreased shrinkage in HMLS yarn.
· Additionally, HMLS yarn contains the highest proportion of tie molecules among the four types of yarns examined. This unique blend of characteristics makes HMLS yarn the most dimensionally stable among the polyester yarns studied in this research.
· The relationship between birefringence and amorphous orientation of polyester yarn was observed to be linear with a positive slope. Similarly, a linear relationship with a positive slope was found between shrinkage and amorphous orientation of polyester yarn.
· The structure of the undrawn yarn was mostly similar across different types of polyester industrial yarns, with the exception of HMLS yarn.
· Undrawn HMLS yarn displayed significantly higher levels of orientation, crystallinity, and crystal size compared to other polyester yarn types.

Effect of Thermal Aging on Mechanical Properties of High-Tenacity Polyester Yarn

Lemmi, Tsegaye Sh, et al. Materials, 2021, 14(7), 1666.

High-tenacity industrial polyester fibers are often used to produce textile materials for applications in the mechanical rubber products industry. Since the reinforcement process of textile rubber involves a vulcanization process at high temperature with a specific aging time, this work evaluates the effect of aging temperature and time on the mechanical and surface structural properties of high-tenacity polyester yarn.
Evaluation methods and results
· Experiments were conducted on different high-tenacity polyester yarns that were pre-activated and had varying linear densities. The yarn samples were exposed to different temperatures (140, 160, 200, and 220 °C) for periods of 6, 12, and 35 minutes to study their tensile properties and surface changes before and after aging.
· Yarn samples aged at 140 °C and 160 °C for 12 minutes and 35 minutes did not show a difference in strength compared to the unaged yarn. However, the strength decreased when aged above 200 °C. Yarns aged at 200 °C and 220 °C for 12 minutes showed a 4.28% and 18.45% decrease in strength, respectively. The yarn aged at 220 °C for 35 minutes had an average 30.97% lower strength compared to the unaged yarn.
· The elongation of the yarn samples increased with higher temperatures, longer aging times, and greater yarn density. Yarn aged at 220 °C for 6 minutes showed almost five times higher elongation compared to the unaged yarn.
· Furthermore, the surface structure of the fibers was affected by aging at higher temperatures (220 °C) for longer periods (35 minutes).
