AI Technical Summary
Existing nylon fibers are prone to wrinkling during stacking. Traditional stiffening agents do not provide long-lasting results and require ironing to restore their shape, which is insufficient to meet the easy-care needs of a fast-paced lifestyle.
Design a spinneret for producing fold-resistant PA6 fibers. The spinneret holes are arranged in a row of several inverted V-shaped holes. After the filaments are swollen, they stick together to form an M-shape. The spinneret holes are distributed in a diamond shape and are staggered.
The PA6 fiber fabric produced is not prone to wrinkles when folded, is easy to care for, and meets the clothing needs of a fast-paced lifestyle.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a spinning plate for producing crease-resistant PA6 fiber. BACKGROUND
[0002] With the continuous acceleration of modern urban life rhythm, the easy-care feature requirement of clothing is more and more favored by urban white-collar. The nylon is preferred for its excellent comfort performance, but the clothes are prone to wrinkle during stacking, and the wrinkle is not beautiful when wearing. The traditional solution is to add stiffening agent during dyeing and finishing, but the effect will gradually disappear after multiple washing, and ironing treatment is needed to restore flatness. Therefore, it is necessary to study the anti-wrinkle property of nylon fiber and improve its crease resistance and pressure resistance. SUMMARY
[0003] In order to solve the problems existing in the prior art, the utility model provides a spinning plate for producing crease-resistant PA6 fiber, which improves the shape of the fiber itself, ensures the comfort of wearing, and solves the easy-care problem.
[0004] To achieve the above purpose, the utility model takes the technical scheme of a spinning plate for producing crease-resistant PA6 fiber, a plurality of spinning holes are formed on the spinning plate, the cross-sectional shape of the spinning hole is composed of a plurality of inverted V-shaped holes arranged side by side, there is a gap between two adjacent inverted V-shaped holes, and the expanded silk from each inverted V-shaped hole is connected together.
[0005] In an embodiment of the utility model, the cross-sectional shape of the spinning hole is composed of at least two inverted V-shaped holes arranged side by side, which are a first V-shaped hole and a second V-shaped hole, there is a gap between the first V-shaped hole and the second V-shaped hole, and the expanded silk from the first V-shaped hole and the second V-shaped hole is connected together in the shape of M.
[0006] In an embodiment of the utility model, the gap is 0.01-0.08mm.
[0007] In an embodiment of the utility model, the spinning hole has a plurality of rows, and the plurality of spinning holes are distributed in a diamond shape on the spinning plate.
[0008] In an embodiment of the utility model, the spinning holes on each row are staggered above and below each other.
[0009] The technical scheme has the following beneficial effects:
[0010] The spinning hole of the crease-resistant PA6 fiber provided by the utility model is arranged side by side by a plurality of inverted V-shaped holes, which can present the cross-sectional shape of the PA6 fiber as a similar M-shaped spring, which is crease-resistant during stacking of clothing fabric, easy to care, and meets the application requirements of people's fast-paced life clothing. BRIEF DESCRIPTION OF DRAWINGS
[0011] Figure 1 is a structural schematic view of an embodiment of the present application. DETAILED DESCRIPTION
[0012] The present application will be further described below in conjunction with the embodiments and drawings. Figure 1 The present application will be further described below in conjunction with the embodiments and drawings.
[0013] A spinneret 100 for producing crease-resistant PA6 fibers, the spinneret is provided with a plurality of spinneret holes 1, the cross-sectional shape of the spinneret hole is composed of a plurality of inverted V-shaped holes arranged side by side, there is a gap between two adjacent inverted V-shaped holes, and the expanded filaments respectively sprayed from each inverted V-shaped hole are adhered together. The spinneret holes 1 are arranged in several rows, and the spinneret holes are distributed in a diamond shape on the spinneret. The spinneret holes in each row are staggered above and below each other, so that each spinneret hole can be fully cooled by air blowing during spinning.
[0014] In this embodiment, the cross-sectional shape of the spinneret hole is composed of at least two inverted V-shaped holes arranged side by side, which are a first V-shaped hole 10 and a second V-shaped hole 20, and there is a gap between the first V-shaped hole 10 and the second V-shaped hole 20. The expanded filaments respectively sprayed from the first V-shaped hole and the second V-shaped hole are adhered together in an M shape. The gap is 0.01-0.08mm.
[0015] The present application can provide a special M spinneret for crease-resistant PA6 fibers by changing the cross-sectional shape, so that the clothing fabric prepared from the produced PA6 fibers is not easy to have creases, is easy to maintain, and becomes the first choice of urban white-collar workers, thereby meeting the fast-paced daily wear.
[0016] The above specific embodiments are only used to explain and illustrate the present application, but not to limit the present application, and any changes and replacements of the present application without creative labor within the scope of the present application concept and the protection scope of the claims, all fall within the protection scope of the present application patent.
