Description

A wrapped yarn with segment color effect

technical field

The utility model relates to the field of novel yarns, in particular to a wrapping yarn with a segmented color effect.

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.

In view of this, the utility model provides a wrapping yarn with a segment color effect, including a core yarn and an outer wrapping yarn, wherein the core yarn is an untwisted colored roving with fibers arranged in parallel, and the outer wrapping yarn is a colorless staple spun yarn, or The core yarn is an untwisted colorless roving with fibers arranged in parallel, and the outer covering yarn is a colored spun yarn. The outer covering yarn is wrapped in the Z twist direction or the S twist direction outside the core yarn. The spiral wrapping part, the second spiral wrapping part and the third spiral wrapping part, the first spiral wrapping part, the second spiral wrapping part and the third spiral wrapping part are staggered along the yarn length direction, the first The pitch of the helically wrapped part is 1.5-2 times the pitch of the second helically wrapped part, and the pitch of the second helically wrapped part is 2-2.5 times the pitch of the third helically wrapped part. In the utility model, one of the core yarn and the outer wrapping yarn is colored and the other is colorless, and the outer wrapping yarn wraps the core yarn with different pitches to provide a wrapping yarn with a segmented color effect, realizing high added value Production of new fancy yarns.

Contents of the invention

The purpose of the utility model is to provide a wrapping yarn with segment color effect, which can effectively increase the added value of the yarn.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: a wrapping yarn with a segmented color effect, including a core yarn and an outer covering yarn, the core yarn is an untwisted colored roving with fibers arranged in parallel, and the outer covering yarn The yarn is a colorless spun spun yarn, or the core yarn is an untwisted colorless roving with fibers arranged in parallel, the outer covering yarn is a colored spun spun yarn, and the outer covering yarn is wrapped around the core outside the yarn, the wrapping of the outer covering yarn on the outside of the core yarn includes a first helical wrapping part, a second helical wrapping part and a third helical wrapping part, the first helical wrapping part, the second helical wrapping part part and the third helically wrapped part are arranged alternately along the yarn length direction, the pitch of the first helically wrapped part is 1.5-2 times the pitch of the second helically wrapped part, and the pitch of the second helically wrapped part is The pitch is 2-2.5 times of the pitch of the third helical wrapping part.

When spinning, the hollow spindle is provided with a hollow cylinder, and the outer yarn is placed on the hollow cylinder. The core yarn is fed by the rear roller, and after the drafting action of the three rollers, the motor drives the belt pulley to rotate through the belt, and then drives the hollow spindle. Rotate, and then drive the hollow cylinder to rotate, and then drive the outer yarn to rotate. The outer yarn penetrates through the round hole on the hollow spindle, and driven by the rotation of the hollow spindle, it is wrapped in Z twist or S twist at the same time after drafting At the same time, by controlling the rotation of the hollow cylinder, the wrapping yarn can be wrapped with different pitches on the core yarn to complete the spinning process.

The advantages and beneficial effects of the utility model lie in that one of the core yarn and the outer wrapping yarn is colored and the other is colorless, and the outer wrapping yarn wraps the core yarn with different pitches to provide a wrapping with segmental color effect. Yarn, realizing the production of new fancy yarn with high added value.

Description of drawings

Fig. 1 is a schematic diagram of the yarn structure of the present utility model.

Specific implementation methods:

As shown in Figure 1, a wrapping yarn with a segmented color effect includes a core yarn 1 and an outer covering yarn 2, wherein the core yarn 1 is a non-twisted colored roving with fibers arranged in parallel, and the outer covering yarn 2 is a colorless short-fiber spun yarn , or the core yarn 1 is an untwisted colorless roving with fibers arranged in parallel, the outer covering yarn 2 is a colored staple fiber spun yarn, the outer covering yarn 2 is wrapped outside the core yarn 1 with Z twist or S twist, and the outer covering yarn 2 is wrapped around the core The outer wrapping of the yarn 1 includes a first helical wrapping part 3, a second helical wrapping part 4 and a third helical wrapping part 5, the first helical wrapping part 3, the second helical wrapping part 4 and the third helical wrapping part The wrapping parts 5 are staggered along the yarn length direction, the pitch of the first helical wrapping part 3 is 1.5-2 times the pitch of the second helical wrapping part 4, and the pitch of the second helical wrapping part 4 is the third helical pitch 2-2.5 times the pitch of the wrapped part 5.

When spinning, the hollow spindle is provided with a hollow cylinder, and the outer yarn 2 is placed on the hollow cylinder, and the core yarn 1 is fed by the back roller, and after the drafting effect of the three rollers, the motor drives the belt pulley to rotate through the belt, and then drives the The hollow spindle rotates, and then drives the hollow cylinder to rotate, and then drives the outer covering yarn 2 to rotate. The outer covering yarn 2 penetrates through the round hole on the hollow spindle, and driven by the rotation of the hollow spindle, it is wrapped in the Z-twisting or S-twisting direction at the same time. Outside the core yarn 1 after being drafted, the wrapping yarn 2 with different pitches on the core yarn 1 can be realized by controlling the rotation of the hollow cylinder at the same time, and the spinning process is completed.
