Description

A production device for double-covered yarn

technical field

The invention relates to a production device of covered yarn, in particular to a production device of double covered yarn.

Background technique

Cover spinning, also known as wrap spinning, is a new spinning technology that uses hollow spindles for spinning. It uses filament or untwisted parallel staple fiber as the core yarn, and the outsourcing filament or spun yarn wraps the core yarn in a spiral manner.

The common covering spinning methods are as follows: one is that the yarn core and the outer fiber are both short fibers; the other is that the yarn core is made of filament, and the short fiber is the outer fiber; the other is that the short fiber bundle is used as the yarn core. The outside is wrapped with filaments; there is also a filament that is used for both the yarn core and the outer fiber. The yarn strength of synthetic filament covered yarn is higher than that of general staple fiber covered yarn, but the surface of the yarn lacks the characteristics of natural fibers.

Contents of the invention

The object of the present invention is to provide a double-covered yarn production device, which has a simple structure and is easy to operate, and the double-covered yarn produced has good hand feeling, good heat preservation and uniform yarn formation.

To achieve the above object, the present invention is achieved through the following technical solutions:

A production device for double-covered yarns, comprising wire feed rollers, two symmetrical wire feed rollers, and spandex filaments are placed between the two wire feed rollers, and a preset Drafting rollers and press rollers, the press rollers are located above the pre-drawing rollers and are in contact with the pre-drawing rollers, 2 sets of guide wire assemblies are installed above the press rollers, and the guide wire assemblies include guide wires Porcelain parts and hollow spindles, the guide wire porcelain parts are located above the hollow spindle, overfeeding wheels are installed above the guide wire porcelain parts, and above the overfeeding wheels are 2 sets of relaxation coiling devices, the The slack coiling device comprises a coiling roller and a guide wire nozzle, and the described guide wire nozzle is located at the upper right of the coiling roller;

The production process of the double-covered yarn includes the following steps: placing the endless plain spandex yarn on the wire feed roller, and the rotation of the wire feed roller drives the spandex yarn to rotate and decompose; the spandex yarn is fed to the hollow spindle after passing through the pre-drawing roller , when the spandex is output from the core hole of the hollow spindle, the high-speed rotation of the hollow spindle drives the outer covering yarn mounted on the hollow spindle to rotate at a high speed, and under the action of the yarn guide porcelain, the outer covering yarn forms a wrapping air circle And wrapped on the spandex yarn to form a single-layer covered yarn; after passing through the overfeed wheel and the guide wire nozzle, the yarn is wound onto the simple tube, the upper and lower hollow spindles are aligned, and the lower hollow spindle is wrapped When the last covered yarn passes through the upper hollow spindle rotating in reverse at high speed, it can form a double covered yarn.

The highest spindle speed of the hollow spindle is 26000r/min.

The beneficial effects of the present invention are as follows:

The double-covered yarn production device of the present invention has simple structure, easy operation, high production efficiency and qualified rate, and the prepared double-covered yarn has good hand feeling, good heat preservation and uniform yarn formation.

Description of drawings

Fig. 1 is a structural representation of the present invention;

Among them, 1 is wire feeding roller, 2 is spandex yarn, 3 is pre-drawing roller, 4 is pressure roller, 5 is hollow spindle, 6 is guide wire porcelain, 7 is overfeeding wheel, 8 is take-up roller, 9 10 is a guide wire tip, and 10 is a double-covered yarn.

Detailed ways

The present invention will be further described below in conjunction with specific examples, but the protection scope of the present invention is not limited thereto.

As shown in Figure 1, the production device of the double-covered yarn of the present invention comprises wire feed roller 1, and wire feed roller 1 is 2 symmetrically, and spandex filament 2 is placed between 2 wire feed rollers 1, wire feed A pre-drawing roller 3 and a pressure roller 4 are arranged above the roller 1. The pressure roller 4 is located above the pre-drawing roller 3 and is in contact with the pre-drawing roller 3. Two sets of guide wire assemblies are installed above the pressure roller 4. The guide wire assembly in the invention comprises a guide wire porcelain part 6 and a hollow spindle 5, the guide wire porcelain part 6 is positioned above the hollow spindle 5, an overfeeding wheel 7 is installed above the guide wire porcelain part 6, and the top of the overfeed wheel 7 is 2 sets of slack coiling devices, the slack coiling device in the present invention includes a coiling roller 8 and a guide wire nozzle 9, and the guide wire nozzle 9 is located at the top right of the coiling roller 8.

The production process of the double-covered yarn in the present invention comprises the following steps: placing the endless plain spandex yarn 2 on the wire feed roller 1, the rotation of the wire feed roller 1 drives the spandex yarn 2 to rotate and detach; the spandex yarn 2 is pre-drawn The stretching roller 3 is fed to the hollow spindle 5. When the spandex yarn 2 is output from the core hole of the hollow spindle 5, the high-speed rotation of the hollow spindle 5 drives the outer wrapping yarn mounted on the hollow spindle 5 to rotate at a high speed. Under the action of the yarn ceramic part 6, the outer covering yarn forms a wrapping balloon and is wrapped on the spandex yarn 2 to form a single-layer covering yarn; after the overfeeding wheel 7 and the guide wire nozzle 9, it is wound on the simple tube, Align the upper and lower hollow spindles 5, and when the covered yarn wrapped by the lower hollow spindle 5 passes through the upper hollow spindle 5 rotating in reverse at high speed, the double covered yarn 10 can be formed.

The highest spindle speed of the hollow spindle 5 in the present invention is 26000r/min.

The double-covered yarn production device of the present invention has simple structure, easy operation, high production efficiency and qualified rate, and the prepared double-covered yarn has good hand feeling, good heat preservation and uniform yarn formation.

The above-mentioned embodiments are only used to explain the inventive concept of the present invention, but not to limit the protection of the rights of the present invention. Any insubstantial changes made to the present invention by using this concept should fall within the scope of protection of the present invention.
