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 three-filament wrapping parallel spinning yarn, a spinning device and a spinning method, the yarn includes an inner core yarn layer and an outer wrapping layer, and the inner core yarn layer is a staple fiber with a weak twist yarn or a combination of spun yarn and core yarn, the outer wrapping layer includes three wrapping yarns or two wrapping yarns, the outer wrapping layer obtains the final required yarn by wrapping the inner core yarn layer, during spinning , by installing three yarn bobbins arranged up and down on the hollow spindle, and the yarn bobbins and the hollow spindle are connected by controllable gears, and then the controllable feeding of three wrapped yarns is realized. By adopting this method, the controllable wrapping of the three filaments of the inner core yarn layer can be realized, thereby improving the yarn quality, enriching the appearance style of the yarn, and increasing the added value of the product.
