Description

Technical Field

[0001] The invention relates to the technical field of three-dimensional embroidery, in particular to a multi-faceted three-dimensional embroidery and a manufacturing process thereof. Background Art

[0002] Three-dimensional embroidery is to use embroidery thread to wrap the filling material inside to form a three-dimensional pattern. In the prior art, the filling material is mostly EVA glue. The specific process is to adhere EVA to a base such as a fabric, and the embroidery needle penetrates the EVA material and the base layer, so that the embroidery thread wraps the EVA material and the base layer, and then the filling material not covered by the embroidery thread is torn off to obtain the expected pattern. This prior art is difficult to form a highly varied three-dimensional embroidery, and it is difficult to meet the consumer's requirements for three-dimensional embroidery. In addition, during the production process, the torn filling material causes a lot of waste, and the filling material is adhered to the base layer by an adhesive, which is not conducive to environmental protection. Summary of the invention

[0003] In order to solve the above technical problems, the present invention proposes a multi-faceted three-dimensional embroidery, comprising an embroidery thread portion, a filling layer and a base layer, wherein the embroidery thread portion is at least one layer of embroidery thread, the bottom surface of the filling layer is connected to at least a part of the base surface layer, and the embroidery thread portion wraps the filling layer and the base layer covered by it.

[0004] The filling layer includes a protruding portion and a connecting portion, wherein the protruding portion is integrally connected to the connecting portion and is arranged at intervals, and the protruding portion and the bottom surface of the connecting portion are both planar structures located at the same horizontal plane.

[0005] The protrusion is a prism-shaped body with at least three side surfaces, narrow at the top and wide at the bottom.

[0006] The connecting part is a belt-like structure and its height is lower than the protruding part. The connecting part connects the protruding part along the lower bottom surface edge of the protruding part. The embroidery thread wraps the protruding part and the base layer by passing through the connecting part up and down.

[0007] Furthermore, the embroidery thread portion is 2-5 layers of embroidery thread.

[0008] Furthermore, the upper surface of the protrusion is linear or planar.

[0009] Furthermore, the lower bottom surface of the protrusion is an arbitrary polygon.

[0010] Furthermore, the width of the connecting portion is 0.5-2 mm.

[0011] Furthermore, the apex height of the multi-faceted three-dimensional embroidery is 2.5-4 mm.

[0012] Furthermore, the embroidery thread completely covers the connecting portion.

[0013] Furthermore, the filling layer material is a hot-melt material.

[0014] Furthermore, the filling layer material is a hot-melt material such as silicone, silicone blend, PPR, etc., and the hardness of the filling material is selected or adjusted according to the needs of the pattern. If a three-dimensional pattern with soft surface lines is required, a filling material with a softer material needs to be selected, such as pure silicone with a lower hardness. If a three-dimensional pattern with a standing effect is required, a filling material with a harder material needs to be selected, such as adding a hot-melt material with a higher hardness to the hot-melt silicone to obtain a silicone blend with a higher hardness, and then the desired shape is obtained through a mold.

[0015] A process for producing multi-faceted three-dimensional embroidery as claimed in claim 1, comprising the following steps:

[0016] A. Making a filling layer: using a device with a mold to press the filling material, the shape of the mold is a plurality of prisms with at least three sides, which are narrow at the top and wide at the bottom, and a strip-shaped groove, to obtain a filling layer that conforms to the shape of the mold, wherein the protruding portion and the connecting portion of the filling layer are integrally made and spaced apart, the bottom surfaces of the two are integrally connected and are in the same horizontal plane, and the bottom surfaces thereof are both flat, the protruding portion is a prism with at least three sides, which is narrow at the top and wide at the bottom, the connecting portion is a strip-shaped structure and its height is lower than the protruding portion, and the connecting portion connects the protruding portions along the lower bottom surface edge of the protruding portions.

[0017] B. Fixing the filling layer: fixing the lower bottom surface of the filling layer to the upper surface of the base layer, wherein the cross-sectional area of ​​the bottom surface of the filling layer is smaller than that of the base layer.

[0018] C. Embroidery: Embroidery is performed using embroidery equipment, and an embroidery needle with embroidery thread pierces the upper and lower parts of the connecting part to form a three-dimensional embroidery that wraps the protruding part and the base layer.

[0019] Furthermore, the pressing of the filling layer in step A can be hot pressing or cold pressing. During the manufacturing process, the filling material can be a fluid material that is cooled and shaped through a mold opening, or a solid material that is formed into a corresponding shape through pressure.

[0020] Furthermore, in step B, the filling layer may be fixed by adhesion or by point-shaped fixation at the connection portion through a linear material.

[0021] In addition to providing the connection part at the connection of the protrusion, the connection part can also be provided at the outer edge of the overall pattern, so as to facilitate the use of linear materials to fix the filling layer by point-shaped fixation at the connection part.

[0022] Beneficial effects:

[0023] 1. The filling layer of the present invention is made by a device with a mold, and any three-dimensional shape can be easily obtained, that is, the bottom of the three-dimensional shape can be a regular polygon or an irregular polygon, a straight line or a curve, so that the height variation of the three-dimensional embroidery is richer.

[0024] 2. The present invention provides a connecting portion for connecting the protruding portion, so that the protruding portion can obtain a three-dimensional pattern with a splicing effect and a high degree of rich changes within the pattern range, and because the height of the connecting portion is generally less than 1 mm, the filling layer can be fixed to the base material through a dotted wire on the connecting portion, as an alternative to adhesive fixation, and it is more environmentally friendly than adhesive fixation.

[0025] 3. The present invention preferably uses hot-melt materials as filling materials, which can realize the recycling of residual materials, reduce waste, save costs, and obtain filling materials of different hardness by mixing hot-melt filling materials to meet the needs of different three-dimensional patterns.
