Abstract

The research develops a synthetic yarn with combination of 2 polymers (bicomponent) to produce a bicomponent yarn with certain characteristics. The bicomponent polypropylene yarn side by side was successfully carry out in this research and the result were analyzed. The yarn tensile strength is 3.80 g/denier, the elongation is 78.89 %, and the yarn number is 72 denier, according to the results of the analysis. The morphology of the longitudinal and transverse bicomponent yarns was examined under a microscope, revealing the bicomponent yarn's side-by-side structure, which created two colored yarns, black and white.

Abstract

Polyester is a type of polymer commonly used in the production of bottle packaging and textile products. However, polyester takes hundreds of years to decompose naturally, making polyester waste management a critical issue. One of the emerging solutions is the production of recycled polyester. In Indonesia, the utilization of recycled polyester has seen significant growth, particularly in the textile and fashion industries. Several studies have shown that recycled polyester exhibits the same tensile strength and tear resistance as virgin polyester, but with higher stiffness, making it more suitable for geotextile applications. For example, polyester-based plastics are often used as protection in road casting. This study aims to develop nonwoven geotextile using a blend of recycled polyester and low melt polyester fibers with a basis weight of 150 g/m2. Test results indicate that the geotextile fabric has a tensile strength of 240 N, a tear strength of 109.06 N, and a concrete compressive strength of 18.91 MPa.
