In the process of processing High Tenacity Polyester Filament Bonded Twisted Yarn in the textile industry, for the performance of the fabric, the method of twisting the yarn is usually adopted to obtain the strength and elasticity of the yarn. Compared with the pre-twisting process, High Tenacity Polyester Filament Bonded Twisted Yarn has better performance in all aspects.

During the twisting process of High Tenacity Polyester Filament Bonded Twisted Yarn, due to the fiber movement, from the inner layer of the yarn to the outer layer, and then from the outer layer to the inner layer, it moves repeatedly for many times, and the fibers are spiral around the axis of the yarn. The radius decreases alternately along the axis. At this time, the fibers with long length tend to tend to the axis of the yarn more, and the fibers with short length tend to tend to the outer layer of the yarn. The finer fibers tend to the axis of the yarn, and the coarser fibers tend to the outer layer of the yarn. There are more fibers with smaller initial modulus than in the outer layer, and more fibers with larger initial modulus than in the inner layer. Reasonable selection of fibers with different properties can be spun into yarns of different styles to suit different fabric uses or wearing properties.

Since High Tenacity Polyester Filament Bonded Twisted Yarn can arbitrarily select the length, fineness and cross-sectional shape of the fiber, the outer fabric should be blended with chemical fiber and cotton with slightly thicker fiber and slightly shorter length to increase the texture of the yarn surface.
