The second weft inserter introduces the second weft yarn into the seventeenth weaving opening along the width direction, interweaving with a warp yarn on the left edge of the second layer warp yarn left projection warp yarn segment and the third layer left warp yarn, thereby connecting the woven left-side wrinkled lace to the woven elastic band body through the left edge of the second layer warp yarn left projection warp yarn segment.

[0057] One warp yarn on the right edge of the right projection warp yarn section of the second layer and the right warp yarn of the third layer exchange positions along the rising and falling direction to form the eighteenth weaving opening. The second weft inserter introduces the second weft yarn into the eighteenth weaving opening along the width direction, interweaving with one warp yarn on the right edge of the right projection warp yarn section of the second layer and the right warp yarn of the third layer. Thus, the right-side pleated lace is connected to the main body of the elastic band through the right edge of the right projection warp yarn section of the second layer.

[0074] It should be noted that the terms "up", "down", "left", "right", "front", and "back" used in this invention are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0075] Combination Figure 1 and Figure 2 According to an embodiment of the present invention, an elastic band with a reflective wrinkled lace edge on the surface is provided, comprising: an elastic band body 1.

[0076] On the surface of the elastic band body 1, a left-side wrinkled lace 5 extending along the length direction is connected to the left side in the width direction. On the surface of the elastic band body 1, a right-side wrinkled lace 2 extending along the length direction is connected to the right side in the width direction.

[0077] Specifically, the left edge of the left-side wrinkled lace 5 is connected to the surface of the elastic band body 1 via the left connecting position 7, while the rest of the lace is suspended above the surface of the elastic band body 1. The left edge of the right-side wrinkled lace 2 is connected to the surface of the elastic band body 1 via the right connecting position 4, while the rest of the lace is suspended above the surface of the elastic band body 1.

[0078] According to an embodiment of the present invention, at least one left functional line 6 extending along the length direction is woven into the left-side pleated lace 5. At least one right functional line 3 extending along the length direction is woven into the right-side pleated lace 2. Further, the left functional line 6 and the right functional line 3 are reflective lines, or luminous lines, or a combination of reflective lines and luminous lines (reflective lines + luminous lines).

[0079] When the elastic band body 1 is taut, the elastic band body 1, the left wrinkled lace 5 and the right wrinkled lace 2 are all in a straight state.

[0080] When the elastic band body 1 contracts, the elastic band body 1, the left connecting position 7, and the right connecting position 4 contract simultaneously; the left wrinkled lace edge 5 and the right wrinkled lace edge 2 remain suspended on the elastic band body and do not contract. Under the contraction of the elastic band body 1, the left connecting position 7, and the right connecting position 4, the left wrinkled lace edge 5 and the right wrinkled lace edge 2 are squeezed, folded, and wrinkled along the length direction, making them beautiful and attractive.

[0081] In this invention, at least one left functional line 6 extending along the length direction is woven into the left-side wrinkled lace 5, and at least one right functional line 3 extending along the length direction is woven into the right-side wrinkled lace 2. This increases the aesthetics and brightness of the elastic band, while also providing a safety protection function and enhancing the usability of the elastic band.

[0084] like Figure 3 As shown, within the width range of the elastic band body 1, a first layer of warp yarns 8 is arranged along the width direction, and the first layer of warp yarns 8 extends along the length direction. The first layer of warp yarns 8 includes at least a first 420D / 260 / 75D / 75D spandex-covered yarn. The first 420D / 260 / 75D / 75D spandex-covered yarn is arranged along the width direction within the width range of the elastic band body 1.

[0085] Specifically, during warp arrangement, the warp density of the first layer of warp yarns 8 is 100-103 yarns / 10mm. The arrangement parameters of the first layer of warp yarns 8 are as follows: 7-9 150D / 48f polyester DTY warp yarns are arranged along the width direction, with a twist of 80-120 twists / m, and one first 420D / 260 / 75D / 75D spandex covered yarn is arranged, and this pattern is continuously filled within the width range of the elastic band body 1. The parameters of the first 420D / 260 / 75D / 75D spandex covered yarn are: 420D spandex / maximum stretch ratio 2.60 times / positive wrap 75D polyester / negative wrap 75D polyester.

[0086] like Figure 3 As shown, within the width of the elastic band body 1, a second layer of warp yarns 9 is arranged along the width direction, and the second layer of warp yarns 9 extends along the length direction. The second layer of warp yarns 9 includes at least a second 420D / 260 / 75D / 75D spandex-covered yarn. The second 420D / 260 / 75D / 75D spandex-covered yarn is arranged along the width direction outside the width of the left crinkled lace 5 and the right crinkled lace 2.

[0087] Specifically, when arranging the warp yarns, the warp density of the second layer of warp yarns 9 is 100-103 yarns / 10mm. The arrangement parameters of the second layer of warp yarns 9 are: 7-9 150D / 48f polyester DTY warp yarns arranged along the width direction, with a twist of 80-120 twists / m, and 1 second 420D / 260 / 75D / 75D spandex covered yarn.

[0088] The second 420D / 260 / 75D / 75D spandex-covered yarn is arranged along the width direction outside the width of the left-hand crinkled lace 5 and the right-hand crinkled lace 2 (the second 420D / 260 / 75D / 75D spandex-covered yarn is not arranged within the width of the left-hand crinkled lace 5 and the right-hand crinkled lace 2), and this arrangement continues to fill the width of the elastic band body 1. The parameters of the second 420D / 260 / 75D / 75D spandex-covered yarn are: 420D spandex / maximum stretch ratio 2.60 times / front wrap 75D polyester / back wrap 75D polyester.

The width of the right warp yarn 10-2 in the third layer is the same as the width of the right pleated lace 2, and it is used to weave the right pleated lace 2.

[0091] Specifically, when the warp yarns are arranged, the warp density of the third layer of warp yarns (the left warp yarn 10-1 and the right warp yarn 10-2 of the third layer) is 58-60 yarns / 10mm.

[0092] The arrangement parameters for the third layer of warp yarns (third layer left warp yarn 10-1 and third layer right warp yarn 10-2) are as follows: 150D / 48f polyester DTY warp yarns, twisted at 80-120 twists / m, and functional yarns with a diameter of 0.36-0.40mm. The ratio of the number of functional yarns to the number of 150D / 48f polyester DTY warp yarns is 1:10-20. The functional yarns are reflective, luminous, or a combination of reflective and luminous (reflective + luminous).

[0093] like Figure 3As shown, when the warp yarns are arranged, the first layer of warp yarns 8 extends beyond the left edge of the projection of the third layer's left warp yarn 10-1, forming the left outer warp yarn segment 8-1. The first layer of warp yarns 8 extends within the projection range of the third layer's left warp yarn 10-1, forming the left projection warp yarn segment 8-2. The first layer of warp yarns 8 extends within the range of the right edge of the projection of the third layer's left warp yarn 10-1 and the left edge of the projection of the third layer's right warp yarn 10-2, forming the middle warp yarn segment 8-3. The first layer of warp yarns 8 extends within the projection range of the third layer's right warp yarn 10-2, forming the right projection warp yarn segment 8-4. The first layer of warp yarns 8 extends beyond the right edge of the projection of the third layer's right warp yarn 10-2, forming the right outer warp yarn segment 8-5.

[0094] like Figure 3 As shown, when the warp yarns are arranged, the second layer of warp yarns 9, outside the left edge of the projection of the third layer's left warp yarn 10-1, forms the left outer warp yarn segment 9-1 of the second layer. The second layer of warp yarns 9, within the projection range of the third layer's left warp yarn 10-1, forms the left projection warp yarn segment 9-2 of the second layer. The second layer of warp yarns 9, within the range of the right edge of the projection of the third layer's left warp yarn 10-1 and the left edge of the projection of the third layer's right warp yarn 10-2, forms the middle warp yarn segment 9-3 of the second layer. The second layer of warp yarns 9, within the projection range of the third layer's right warp yarn 10-2, forms the right projection warp yarn segment 9-4 of the second layer. The second layer of warp yarns 9, outside the right edge of the projection of the third layer's right warp yarn 10-2, forms the right outer warp yarn segment 9-5 of the second layer.

[0095] After the warp yarns are arranged as described above, they are woven with elastic bands.

[0097] Combination Figure 3 According to an embodiment of the present invention, the first layer of warp yarns, left outer warp yarn segment 8-1, the second layer of warp yarns, left outer warp yarn segment 9-1, the first layer of warp yarns, left projection warp yarn segment 8-2, the second layer of warp yarns, left projection warp yarn segment 9-2 near the left edge, the first layer of warp yarns, middle warp yarn segment 8-3, the second layer of warp yarns, middle warp yarn segment 9-3, the first layer of warp yarns, right projection warp yarn segment 8-4, the second layer of warp yarns, right projection warp yarn segment 9-4 near the right edge, the first layer of warp yarns, right outer warp yarn segment 8-4, and the second layer of warp yarns, right outer warp yarn segment 9-5, are introduced with weft yarns (introduced along the width direction) to jointly weave the elastic band body 1.

[0098] The left warp yarn 10-1 of the third layer and the other half (away from the left half) of the left projection warp yarn segment 9-2 of the second layer are joined by weft yarns (introduced along the width direction) to weave the left-side crinkled lace 5. The right warp yarn 10-2 of the third layer and the other half (away from the right half) of the right projection warp yarn segment 9-4 of the second layer are joined by weft yarns (introduced along the width direction) to weave the right-side crinkled lace 2.

[0099] The left edge of the second layer warp yarn left projection warp yarn segment 9-2 connects the woven left-side pleated lace 5 to the woven elastic band body 1. The right edge of the second layer warp yarn right projection warp yarn segment 9-4 connects the woven right-side pleated lace 2 to the woven elastic band body 1.

[0100] Specifically, such as Figure 3 As shown, according to an embodiment of the present invention, the elastic band is woven in the following manner:

[0101] First weaving cycle:

[0102] A first weft inserter (lower weft inserter / lower guide shuttle) and a second weft inserter (upper weft inserter / upper guide shuttle) are provided to reciprocate within the width range of the elastic band body 1 along the width direction. The first weft inserter and the second weft inserter work synchronously (the first weft inserter and the second weft inserter are not shown in the figure).

[0103] like Figure 3 As shown, the left outer warp segment 9-1 of the second layer of warp rises along the lifting direction and forms the first weaving opening with the left outer warp segment 8-1 of the first layer of warp; the left projection warp segment 9-2 of the second layer of warp rises along the lifting direction near the left half and forms the second weaving opening with the left projection warp segment 8-2 of the first layer of warp.

[0104] The middle warp segment 9-3 of the second layer rises along the lifting direction until it is on the same plane as the left warp segment 10-1 of the third layer and the right warp segment 10-2 of the third layer. The middle warp segment 9-3 of the second layer and the middle warp segment 8-3 of the first layer form the third weaving opening.

[0105] The right projection warp segment 9-4 of the second layer of warp yarns rises along the lifting direction to form the fourth weaving opening with the right projection warp segment 8-4 of the first layer of warp yarns; the right outer warp segment 9-5 of the second layer of warp yarns rises along the lifting direction to form the fifth weaving opening with the right outer warp segment 8-5 of the first layer of warp yarns.

[0106] The first weft inserter (lower weft inserter / lower guide shuttle) introduces the first weft yarn into the first weaving opening, the second weaving opening, the third weaving opening, the fourth weaving opening and the fifth weaving opening along the width direction, and interweaves it with the first layer of warp yarn 8 and the second layer of warp yarn 9 to weave the elastic band body 1.

[0107] At the same time, the left warp 10-1 of the third layer and the other half (far from the left half) of the left projection warp segment 9-2 of the second layer form the sixth weaving opening; the right warp 10-2 of the third layer and the other half (far from the right half) of the right projection warp segment 9-4 of the second layer form the seventh weaving opening.

[0108] The second weft inserter (upper weft inserter / upper shuttle) guides the second weft yarn into the sixth weaving opening along the width direction. This yarn interweaves with the other half (away from the left half) of the third layer's left-side warp yarn 10-1 and the second layer's left-projection warp yarn segment 9-2, together weaving the left-side crinkled lace 5. The second weft inserter (upper weft inserter / upper shuttle) then guides the second weft yarn into the seventh weaving opening along the width direction. This yarn interweaves with the other half (away from the right half) of the third layer's right-side warp yarn 10-2 and the second layer's right-projection warp yarn segment 9-4, together weaving the right-side crinkled lace 2.

[0109] The second weft inserter (upper weft inserter / upper shuttle) introduces the second weft yarn into the third weaving opening formed by the middle warp yarn segment 9-3 of the second layer of warp yarn and the middle warp yarn segment 8-3 of the first layer of warp yarn along the width direction, and interweaves with the first layer of warp yarn 8 and the second layer of warp yarn 9 to weave the elastic band body 1.

[0110] In this invention, the first weft yarn is introduced into the middle warp section 9-3 of the second layer of warp yarns and the middle warp section 8-3 of the first layer of warp yarns by the first weft introducer (lower weft introducer / lower guide shuttle) along the width direction, and the second weft yarn is introduced into the middle warp section 8-3 of the first layer of warp yarns by the second weft introducer (upper weft introducer / upper guide shuttle) along the width direction. That is, in one cycle, there are two weft yarns between the middle warp section 9-3 of the second layer of warp yarns and the middle warp section 8-3 of the first layer of warp yarns.

[0111] At the same time, a warp yarn on the left edge of the second layer warp yarn left projection warp yarn segment 9-2 forms the eighth weaving opening with the third layer left warp yarn 10-1. The second weft inserter (upper weft inserter / upper shuttle) introduces the second weft yarn into the eighth weaving opening along the width direction, interweaving with a warp yarn on the left edge of the second layer warp yarn left projection warp yarn segment 9-2 and the third layer left warp yarn 10-1 to form the left connection position 7. Thus, the woven left-side wrinkled lace 5 is connected to the woven elastic band body 1 through the left edge of the second layer warp yarn left projection warp yarn segment 9-2.

[0112] A warp yarn along the right edge of the right projection warp yarn segment 9-4 of the second layer forms the ninth weaving opening with the right side warp yarn 10-2 of the third layer. The second weft inserter (upper weft inserter / upper shuttle) introduces the second weft yarn into the ninth weaving opening along the width direction. It interweaves with a warp yarn along the right edge of the right projection warp yarn segment 9-4 of the second layer and the right side warp yarn 10-2 of the third layer to form the right connection position 4. Thus, the right-side pleated lace 2 is connected to the woven elastic band body 1 through the right edge of the right projection warp yarn segment 9-4 of the second layer.

[0113] Second weaving cycle:

[0114] like Figure 3 As shown, the left outer warp segment 9-1 of the second layer warp yarns and the left outer warp segment 8-1 of the first layer warp yarns exchange positions along the lifting direction to form the tenth weaving opening; the left projection warp segment 9-2 of the second layer warp yarns, near the left half, and the left projection warp segment 8-2 of the first layer warp yarns exchange positions along the lifting direction to form the eleventh weaving opening.

[0115] The middle warp segment 8-3 of the first layer rises along the lifting direction until it is on the same plane as the left warp segment 10-1 of the third layer and the right warp segment 10-2 of the third layer. The middle warp segment 9-3 of the second layer descends along the lifting direction to the lowest position. The middle warp segment 9-3 of the second layer and the middle warp segment 8-3 of the first layer exchange positions to form the twelfth weaving opening.

[0116] The right half of the second layer warp yarn right projection warp yarn segment 9-4 and the right half of the first layer warp yarn right projection warp yarn segment 8-4 exchange positions along the rising and falling direction to form the thirteenth weaving opening; the right outer warp yarn segment 9-5 of the second layer warp yarn and the right outer warp yarn segment 8-5 of the first layer warp yarn exchange positions along the rising and falling direction to form the fourteenth weaving opening.

[0117] The first weft inserter (lower weft inserter / lower guide shuttle) introduces the first weft yarn into the tenth, eleventh, twelfth, thirteenth and fourteenth weaving openings along the width direction, interweaving with the first layer of warp yarns 8 and the second layer of warp yarns 9 to weave the elastic band body 1.

[0118] At the same time, the left warp 10-1 of the third layer and the other half (the half away from the left side) of the left projection warp segment 9-2 of the second layer exchange positions along the lifting direction to form the fifteenth weaving opening; the right warp 10-2 of the third layer and the other half (the half away from the right side) of the right projection warp segment 9-4 of the second layer exchange positions along the lifting direction to form the sixteenth weaving opening.

[0119] The second weft inserter (upper weft inserter / upper shuttle) guides the second weft yarn into the fifteenth weaving opening along the width direction. It interweaves with the left warp yarn 10-1 of the third layer and the other half (the half furthest from the left) of the left projection warp yarn segment 9-2 of the second layer, together weaving the left-side crinkled lace 5. The second weft inserter (upper weft inserter / upper shuttle) guides the second weft yarn into the sixteenth weaving opening along the width direction. It interweaves with the right warp yarn 10-2 of the third layer and the other half (the half furthest from the right) of the right projection warp yarn segment 9-4 of the second layer, together weaving the right-side crinkled lace 2.

[0120] The second weft inserter (upper weft inserter / upper shuttle) introduces the second weft yarn into the twelfth weaving opening formed by the middle warp yarn segment 9-3 of the second layer of warp yarn and the middle warp yarn segment 8-3 of the first layer of warp yarn along the width direction, and interweaves with the first layer of warp yarn 8 and the second layer of warp yarn 9 to weave the elastic band body 1.

[0121] In this invention, the first weft yarn is introduced into the middle warp section 9-3 of the second layer of warp yarns and the middle warp section 8-3 of the first layer of warp yarns by the first weft introducer (lower weft introducer / lower guide shuttle) along the width direction, and the second weft yarn is introduced into the middle warp section 8-3 of the first layer of warp yarns by the second weft introducer (upper weft introducer / upper guide shuttle) along the width direction. That is, in one cycle, there are two weft yarns between the middle warp section 9-3 of the second layer of warp yarns and the middle warp section 8-3 of the first layer of warp yarns.

[0122] At the same time, a warp yarn on the left edge of the second layer warp yarn left projection warp yarn segment 9-2 and the third layer left warp yarn 10-1 exchange positions along the lifting direction to form the seventeenth weaving opening. The second weft inserter (upper weft inserter / upper shuttle) introduces the second weft yarn into the seventeenth weaving opening along the width direction, and interweaves with a warp yarn on the left edge of the second layer warp yarn left projection warp yarn segment 9-2 and the third layer left warp yarn 10-1 to form the left connection position 7. Thus, the woven left-side wrinkled lace 5 is connected to the woven elastic band body 1 through the left edge of the second layer warp yarn left projection warp yarn segment 9-2.

[0123] One warp yarn along the right edge of the second layer warp yarn right projection warp yarn segment 9-4 and the third layer right warp yarn 10-2 exchange positions along the lifting direction to form the eighteenth weaving opening. The second weft inserter (upper weft inserter / upper shuttle) introduces the second weft yarn into the eighteenth weaving opening along the width direction, interweaving with one warp yarn along the right edge of the second layer warp yarn right projection warp yarn segment 9-4 and the third layer right warp yarn 10-2 to form the right connection position 4. Thus, the woven right-side pleated lace 2 is connected to the woven elastic band body 1 through the right edge of the second layer warp yarn right projection warp yarn segment 9-4.

[0124] Third weaving cycle:

[0125] Repeat the first weaving cycle, and at the same time, in the second weaving opening formed by the left half of the second layer warp yarn left projection warp yarn segment 9-2 and the first layer warp yarn left projection warp yarn segment 8-2, a warp yarn located on the left edge of the second layer warp yarn left projection warp yarn segment 9-2 and the first layer warp yarn left projection warp yarn segment 8-2 are introduced into the first weft yarn along the width direction for interlacing through the first weft introducer (lower weft introducer / lower guide shuttle).

[0126] In the fourth weaving opening formed by the right half of the second layer warp right projection warp segment 9-4 and the first layer warp right projection warp segment 8-4, a warp yarn located on the right edge of the second layer warp right projection warp segment 9-4 and the first layer warp right projection warp segment 8-4 are interwoven by introducing the first weft yarn along the width direction through the first weft introducer (lower weft introducer / lower guide shuttle).

[0127] Fourth weaving cycle:

[0128] Repeat the second weaving cycle, while the left half of the second layer warp yarn left projection warp yarn segment 9-2 near the left side forms the eleventh weaving opening with the first layer warp yarn left projection warp yarn segment 8-2. Between a warp yarn located on the left edge of the second layer warp yarn left projection warp yarn segment 9-2 and the first layer warp yarn left projection warp yarn segment 8-2, the first weft introducer (lower weft introducer / lower guide shuttle) introduces the first weft yarn along the width direction for interlacing.

[0129] The right half of the second layer warp right projection warp segment 9-4 and the first layer warp right projection warp segment 8-4 form the thirteenth weaving opening. Between a warp yarn located on the right edge of the second layer warp left projection warp segment 9-4 and the first layer warp right projection warp segment 8-4, the first weft introducer (lower weft introducer / lower guide shuttle) introduces the first weft yarn along the width direction for interlacing.

[0130] Repeat the first, second, third, and fourth weaving cycles to complete the elastic band weaving.

[0131] Furthermore, during the weaving process, the first and second weft yarns introduced along the width direction are 75D / 36f polyester DTY weft yarns.

[0132] In this invention, the first layer of warp yarns 8 is filled with first 420D / 260 / 75D / 75D spandex-covered yarn along the width direction within the width range of the elastic band body 1. The second layer of warp yarns 9 is filled with second 420D / 260 / 75D / 75D spandex-covered yarn along the width direction outside the width of the left wrinkled lace 5 and the right wrinkled lace 2 (the second 420D / 260 / 75D / 75D spandex-covered yarn is not filled within the width range of the left wrinkled lace 5 and the right wrinkled lace 2), so that the elastic band body 1 has elasticity and strong shrinkage and rebound ability.

[0133] The second layer of warp yarns 9 is arranged with second 420D / 260 / 75D / 75D spandex-covered yarn along the width direction outside the width of the left wrinkled lace 5 and the right wrinkled lace 2 (the second 420D / 260 / 75D / 75D spandex-covered yarn is not arranged within the width of the left wrinkled lace 5 and the right wrinkled lace 2). The third layer of warp yarns (the third layer left warp yarn 10-1 and the third layer right warp yarn 10-2) does not have 42D spandex-covered yarn. The left wrinkled lace 5 and the right wrinkled lace 2 have no shrinkage elasticity. When the elastic band body 1 shrinks, the elastic band body 1, the left connecting position 7 and the right connecting position 4 shrink simultaneously. The left wrinkled lace 5 and the right wrinkled lace 2 are suspended on the elastic band body and do not shrink. Under the contraction of the elastic band body 1, the left connecting position 7 and the right connecting position 4, the left wrinkled lace 5 and the right wrinkled lace 2 are squeezed, folded and wrinkled along the length direction, which is beautiful and attractive.

[0134] At least one functional thread (left functional thread 6 and right functional thread 3) with a diameter of 0.36-0.40mm is arranged in the third layer left warp 10-1 warp and the third layer right warp 10-2 warp. The left wrinkled lace 5 and the right wrinkled lace 2 have reflective or luminous, or reflective + luminous protective functions, and have reflective or luminous or reflective + luminous stripes, which enhance the aesthetics.
