Description

A Parallel Spinning Device with Double Filament Feed Up and Down

technical field

The utility model relates to the field of novel yarns, in particular to a parallel spinning device for feeding double filaments up and down in opposite directions.

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. Aiming at this, the utility model provides a parallel spinning device with double filaments feeding up and down in opposite directions. The device uses double filaments to be placed in parallel up and down with the same rotation speed but opposite rotation direction, so as to realize the alignment of core yarns in parallel spinning. The reverse double wrapping improves the quality of the yarn. At the same time, the double filaments can be made of different colors or materials, which enriches the appearance of the yarn and increases the added value of the product.
