[0002] Terry stitch is a kind of embroidery, which belongs to three-dimensional embroidery. The effect is very similar to towel cloth, so it is named terry stitch. Terry stitch can embroider any flower shape, any color, and the embroidered flowers, trees, animals, patterns, cartoons, etc. have the characteristics of hierarchy, novelty, strong three-dimensionality, etc., and are widely welcomed by consumers and designers. It can be widely used in clothing, home accessories, handicrafts and other industries.

[0003] In the process of terry stitch embroidery, the bottom thread is loosened and the face thread is tightened, so that the bottom thread is turned up on the embroidery surface. The needle operation method is straight line movement, which must be orderly, so as to produce terry pattern effect like curly hair, making the pattern soft and thick. If the straight line movement is changed to continuous small circle operation when the needle is operated, a series of small chrysanthemum shapes can be produced on the embroidery surface. This needle method is called "turning earth chrysanthemum needle", which is used to embroider pattern cores, and the effect is very good.

DETAILED DESCRIPTION

[0040] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0041] As shown in Figures 1-15 , a terry embroidery embroidery process, comprising a frame 1, the frame 1 is provided with a needle plate 2 and a machine head 3 matched, the needle plate 2 is laid with the required embroidery fabric, and the fabric is sewn with the base thread 10 arranged along the required embroidery pattern, and the face thread 8 is arranged on the needle bar assembly 51 of the machine head 3, the fabric is in a taut state on the needle plate 2, and the upper and lower sides of the fabric can be terry embroidered by pressing the non-embroidered part of the fabric, so as to facilitate the embroidery of the fabric.

[0042] In actual use, the following steps are included:

[0043] Step A: an embroidery thread 9 is arranged on one side of the machine head 3 which moves synchronously with the machine head 3, a lead device 6 is arranged on one side of the machine head 3 for supporting and guiding the embroidery thread 9, and a lead piece 53 is further arranged at the bottom of the machine head 3 for supporting and guiding the embroidery thread 9, under the action of the lead device 6 and the lead piece 53, the stable transmission of the embroidery thread 9 in the embroidery process is ensured.

[0044] Step B: the needle plate 2 is moved relative to the machine head 3, so that the needle bar assembly 51 moves to the initial needle-down position of the fabric, all the needle-down positions of the needle bar assembly 51 correspond to the arrangement of the base thread 10, so as to select and set the embroidery density of the embroidery thread 9 through the arrangement of the base thread 10.

[0045] Step C: the needle bar assembly 51 is lowered, the needle bar assembly 51 synchronously drives the synchronous movement of the face thread 8 and the embroidery thread 9, the needle bar assembly 51 is raised, the needle bar assembly 51 drives the synchronous movement of the face thread 8, the embroidery thread 9 is arranged on the fabric to form a terry structure, and the face thread 8 and the base thread 10 form a thread loop to fix the terry structure formed by the embroidery thread 9 on the fabric.

[0046] The needle bar assembly 51 carries out the needle lowering and needle returning operations at the same position of the fabric, and the bottom thread 10 is sewn on the upper surface of the fabric, so that the setting position of the bottom thread 10 can be directly observed during the needle returning of the needle bar assembly 51, and the needle bar assembly 51 is lowered according to the setting position of the bottom thread 10.

[0047] During the needle lowering of the needle bar assembly 51, the needle bar assembly 51 moves vertically downward towards the fabric, and simultaneously drives the movement of the face thread 8 and the embroidery thread 9. The face thread 8 is arranged in a penetrating manner at the needle head of the needle bar assembly 51, and the embroidery thread 9 abuts against the needle head of the needle bar assembly 51. When the needle bar assembly 51 is lowered, the face thread 8 and the embroidery thread 9 pierce the fabric under the action of the needle lowering of the needle bar assembly 51, so that the face thread 8 and the embroidery thread 9 pierce from the upper layer of the fabric to the lower layer of the fabric. At this time, the embroidery thread 9 is in a tight state under the abutting action of the needle bar assembly 51.

[0048] When the needle bar assembly 51 is returned, the needle bar assembly 51 moves upward to separate from the fabric. At this time, the face thread 8 moves synchronously with the movement of the needle bar assembly 51 due to the penetrating arrangement of the face thread 8 on the needle bar assembly 51. When the face thread 8 moves upward through the bottom thread 10, the face thread 8 and the bottom thread 10 form a thread loop, which binds the loop opening of the loop structure of the embroidery thread 9, so as to fix and clamp the embroidery thread 9 on the fabric.

[0049] The embroidery thread 9 is separated from the needle bar assembly 51 by the movement of the needle bar assembly 51, and the loop opening of the embroidery thread 9 is clamped under the tensioning action of the fabric, so that the embroidery thread 9 after being separated from the needle bar assembly 51 is in a relaxed state. The embroidery thread 9 forms the loop structure on the fabric under the clamping action of the fabric.

[0050] Step D: The needle plate 2 moves relative to the machine head 3 to the next needle lowering position of the fabric, which also corresponds to the bottom thread 10.

[0051] Step E: Repeat steps C-D until the embroidery at all the bottom threads 10 is completed.

[0052] The frame 1 is provided with a thread rack for supplying the face thread 8 and the embroidery thread 9. The thread rack is respectively provided with a thread cylinder for supplying the face thread 8 and a thread cylinder for supplying the embroidery thread 9. The thread cylinders ensure the supply of the face thread 8 and the embroidery thread 9. Meanwhile, the thread guide device 6 and the thread guide piece 53 are arranged on the machine head 3, and the movement of the machine head 3 synchronously drives the movement of the face thread 8 and the embroidery thread 9, so as to ensure the better relative stability between the face thread 8 and the embroidery thread 9.

[0053] The bottom line 10 includes an edge bottom line 10 arranged along the edge of the desired embroidery pattern and a plurality of array bottom lines 10 arranged in the edge bottom line 10, and the needle bar assembly 51 embroiders the fabric at the edge bottom line 10 and the plurality of array bottom lines 10 in turn. In the embroidery process, the edge bottom line 10 arranged along the edge of the desired embroidery pattern can be embroidered first, and then the plurality of array bottom lines 10 can be embroidered to fill the embroidery pattern. The edge bottom line 10 and the plurality of array bottom lines 10 can correspond to the needle bar assembly 51 with different needle drop heights, so as to form different sizes of loop structure of the embroidery thread 9 at the edge bottom line 10 and the plurality of array bottom lines 10, and the whole has better three-dimensionality.

[0054] The plurality of array bottom lines 10 are arranged in rows or columns in the edge bottom line 10. The specific arrangement of the plurality of array bottom lines 10 is set according to actual needs. The plurality of array bottom lines 10 arranged in rows or columns facilitate the needle drop of the needle bar assembly 51.

[0055] The size of the loop structure formed by the embroidery thread 9 is adjusted according to the needle drop distance of the needle bar assembly 51. When the needle drop distance of the needle bar assembly 51 increases, the spacing between the lowest position moved by the needle bar assembly 51 and the fabric increases, so that the number of the embroidery thread 9 piercing through the fabric increases, and the loop structure formed by the embroidery thread 9 also increases accordingly. Similarly, when the needle drop distance of the needle bar assembly 51 decreases, the spacing between the lowest position moved by the needle bar assembly 51 and the fabric decreases, so that the number of the embroidery thread 9 piercing through the fabric decreases, and the loop structure formed by the embroidery thread 9 also decreases accordingly.

[0056] Therefore, by adjusting the needle drop distance of the needle bar assembly 51, the size of the loop structure formed by the embroidery thread 9 can be adjusted during the embroidery process, so that the height of the corresponding loop structure can be adjusted according to the actual embroidered pattern, so that the embroidery pattern forms a three-dimensional structure with uneven height, and better three-dimensionality and aesthetic degree are achieved.
