Description

A core-spun yarn

technical field

The utility model relates to the field of novel yarns, in particular to a core-spun wrapping 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. Parallel spinning is to use a non-twisted parallel fiber strip as the core yarn, outsourcing the filament or spun staple yarn, and wrap it into yarn and then wind it on the bobbin. Since the fiber of the core yarn is 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.

In view of this, the utility model provides a core-spun yarn, which includes a core-layer composite yarn and an outer-wrapped yarn. The core-layer composite yarn includes a first core-spun yarn, a second core-spun yarn, and a third core-spun yarn. The core yarn is arranged in a triangle, and the outer covering yarn is a filament bundle or a two-for-one twisted filament yarn. The outer covering yarn is wrapped in Z twist or S twist on the outside of the core composite yarn, so that the core wrapped yarn can replace the yarn. , with a unique yarn structure, it is suitable for untwisted, weak twisted and piled products, giving people a high-end feeling. At the same time, the core layer adopts three core-spun yarns arranged in a triangle, which can enhance the elasticity of the wrapped yarn And strong, improve yarn quality.

Contents of the invention

The purpose of the utility model is to provide a core-wrapping yarn, which can enhance the elasticity and strength of the wrapping yarn and improve the yarn quality by adopting three core-spun yarns arranged in a triangle in the core layer.

In order to achieve the above object, the technical scheme adopted by the utility model is as follows: a core-spun wrapping yarn, comprising a core-layer composite yarn and an outer-wrapped yarn, the core-layer composite yarn comprising a first core-spun yarn, a second core-spun yarn and The third core-spun yarn, the first core-spun yarn, the second core-spun yarn, and the third core-spun yarn are arranged in a triangle, the first core-spun yarn includes a first outer covering yarn and a first core filament, and the first core-spun yarn includes a first outer covering yarn and a first core yarn. The second core-spun yarn includes a second outer yarn and a second core yarn, the third core yarn includes a third outer yarn and a third core yarn, and the first outer yarn, the second outer yarn and the third outer yarn are all It is a spun yarn, the first core yarn, the second core yarn and the third core yarn are all filaments, the outer covering yarn is a filament bundle or a two-for-one twisted filament yarn, and the outer covering yarn adopts Z twist direction or The S twist direction is wrapped around the core composite yarn, and the first core filament, the second core filament and the third core filament are all made of the same material as the outer filament bundle or the filament two-for-one twisted yarn.

During spinning, the first core-spun yarn, the second core-spun yarn and the third core-spun yarn are spun by core-spun spinning on the ring spinning frame, and then the first core-spun yarn, the second core-spun yarn and the third core-spun yarn are spun The three core yarns are simultaneously fed by the back rollers as the core yarn, and the draft ratio of the three rollers is set to zero. The outer covering yarn is placed on the hollow spindle, and the motor drives the belt pulley to rotate through the belt, and then drives the hollow spindle to rotate, and then The outer covering yarn rotates, and the outer covering yarn penetrates through the round hole on the hollow spindle. Driven by the rotation of the hollow spindle, it is wrapped in the Z-twisting or S-twisting direction outside the core layer composite yarn after zero-fold drafting, and the obtained The required corespun yarn is used to complete the spinning process.

The utility model has the advantages and beneficial effects that: the elasticity and strength of the wrapped yarn can be enhanced by using three core-spun yarns arranged in a triangle in the core layer, and the quality of the yarn can be improved.

Detailed ways:

As shown in Figure 1, Figure 2 and Figure 3, a core-spun wrapping yarn includes a core layer composite yarn 7 and an outer covering yarn 8, wherein the core layer composite yarn 7 includes a first core-spun yarn 1, a second core-spun yarn 2 and the third core-spun yarn 3, the first core-spun yarn 1, the second core-spun yarn 2 and the third core-spun yarn 3 are arranged in a triangle, and the first core-spun yarn 1 includes the first outer covering yarn and the first core yarn 4 , the second core-spun yarn 2 comprises the second outer covering yarn and the second core filament 5, the third core-spun yarn 3 comprises the third outer covering yarn and the third core filament 6, the first outer covering yarn, the second outer covering yarn and the third outer covering yarn The yarns are all spun yarns, the first core yarn 4, the second core yarn 5 and the third core yarn 6 are all filaments, the outer covering yarn 8 is a filament bundle or a filament two-for-one twisted yarn, and the outer covering yarn 8 adopts Z twist direction Or the S twist direction is wrapped around the core layer composite yarn 7, and the first core filament 4, the second core filament 5 and the third core filament 6 are all made of the same material as the outer filament bundle or the filament two-for-one twisted yarn.

During spinning, the first core-spun yarn 1, the second core-spun yarn 2 and the third core-spun yarn 3 are spun by core-spun spinning on the ring spinning frame, and then the first core-spun yarn 1, the second core-spun yarn The core yarn 2 and the third core yarn 3 are simultaneously fed as the core yarn by the rear rollers, and the draft multiple of the three rollers is set to zero, the outer covering yarn 8 is placed on the hollow spindle, and the motor drives the belt pulley to rotate through the belt. Then the hollow spindle is driven to rotate, and then the outer covering yarn 8 is rotated. The outer covering yarn 8 penetrates through the round hole on the hollow spindle. The outer core layer composite yarn 7 is obtained to obtain the required core-spun wrapping yarn, and the spinning process is completed.
