Description

A ring spinning device and spinning method for wrapping yarn

technical field

The invention relates to the field of spinning new technology, in particular to a spinning device and spinning method for wrapping ring spinning yarn.

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 present invention provides a kind of spinning device and spinning method of ring spinning wrapped yarn, adopting this kind of method can realize on the same device, ring spinning, ring spinning parallel yarn, parallel wrapping yarn simultaneously production, thereby greatly improving production efficiency.
