Nylon 66 Natural Stretch Yarn, the process of producing thereof and the process of producing excellent stretching fabrics using thereby

摘要

The invention and the conventional nylon 66 stretch yarn of the polyurethane as it relates to a method of using stretchable fabric to provide a new yarn through the yarn processing of natural fibers itself without the use of elastic fibers as its object . In the present invention , due to the omission of the weaving preparation process than the conventional spandex covering process has a manufacturing cost savings . In addition , conventional anti-wrinkle union cloth poor in dyeing and in accordance with the reduction of stretch material , and to overcome problems such as poor elasticity of the fabric due to the degradation of the polyurethane to provide a highly elastic fabric that can be applied to the field of functional sportswear can be .
