technical field

The utility model relates to the field of novel yarns, in particular to a parallel spinning device for wrapping three filaments in the same direction.

Background technique

Parallel spinning, also known as wrapping spinning, uses a hollow spindle for spinning, and the yarn produced by a parallel spinning machine is called parallel yarn, also known as P.L yarn. In parallel spinning, a non-twisted parallel fiber strip is used as the core yarn, and the outsourcing filament or spun staple yarn is wound on the bobbin after being wrapped into yarn. Since the fibers of the core yarn are not twisted, it is called Parallel spinning. When the yarn is stretched, the filament exerts radial pressure on the short fiber sliver, which causes friction between the short fibers and makes the parallel yarn have a certain strength.

Parallel yarn can replace thread, and it is suitable for untwisted, weak twist and pile products with its unique yarn structure, giving people a high-end feeling. However, the current parallel spinning devices all use a single filament or spun yarn for outsourcing, which limits the type of spinning and the quality of the yarn. In view of this, the utility model provides a parallel spinning device with three filaments wrapping in the same direction. The device uses the first filament, the second filament and the third filament to be placed on the hollow cylinder from top to bottom. The first circular feeding hole, the second circular feeding hole and the third circular feeding hole are sequentially opened on the hollow spindle from bottom to top, and the first guide yarn is installed on the hollow cylinder from bottom to top. At the same time, the first filament directly passes through the first circular feeding hole into the hollow spindle, and the second filament passes through the second yarn guiding hook and then passes through the second circular feeding hole into the hollow spindle , the third filament passes through the first yarn guide hook, the second yarn guide hook, and then passes through the third circular feeding hole into the hollow spindle, realizing the three-wrapping of the core yarn in the same direction in parallel spinning, and then improving At the same time, the double filament can be used in different colors or different materials, thereby enriching the appearance of the yarn and increasing the added value of the product.
