AI Technical Summary
When rope yarn is subjected to tension or after prolonged use, the pulling force of the rope on the yarn decreases, causing the yarn to easily fall off, which affects the softness and warmth of the yarn.
A fixing line is set on the outer peripheral wall of the rope yarn body. The fixing line is pressed towards the axis to form a depression, and a winding line is wrapped around it. The fixing line is made of spandex and polyester fibers twisted together, and the winding line is made of nylon fibers twisted together. The twist direction of the winding line is opposite to that of the fixing line, forming a spiral winding to enhance the connection strength.
The combination of fixing and winding threads reduces yarn swaying and shedding, improves yarn lifespan and softness, and enhances yarn tensile strength and abrasion resistance.

Description
Technical Field
[0001] The utility model relates to the technical field of yarns, and more particularly to high-elastic yarns. Background Art
[0002] Yarn is a product made from various textile fibers processed to a certain fineness. It can be woven into a variety of clothing items. Yarn is a thin, long, thread-like material made from a fiber or fiber blend, commonly used in crafts such as knitting, sewing, crocheting, and weaving. Yarn can be made from many different types of fibers, including cotton, wool, linen, silk, and rayon. Depending on the fiber type and processing method, yarn can have different textures, colors, and properties. Yarn is typically categorized into different gauges based on its thickness, such as thick, medium, and fine. Each gauge of yarn is suitable for different uses. For example, thick yarn is suitable for making heavy items such as sweaters and scarves, while fine yarn is suitable for making light items such as tulle and lace.
[0003] Chenille yarn, also known as chenille yarn, is soft and warm. It consists of two parts: rope and wool. When subjected to large tension or long-term use, the traction of the rope on the wool becomes smaller, which can easily cause the wool to fall off, making the yarn gradually thinner and losing its softness and warmth-keeping effect.
