High modulus low shrinkage polyester filament is a type of polyester filament yarn with high tensile strength and low shrinkage properties. It is commonly used in applications where high performance and dimensional stability are required, such as in industrial sewing threads, automotive upholstery, and technical textiles. The high modulus of the yarn ensures excellent resistance to stretching and deformation, while the low shrinkage ensures that the fabric maintains its shape and size even after multiple washes. Overall, high modulus low shrinkage polyester filament is a versatile and reliable material for a wide range of textile applications.
