It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0044] Example 1

[0045] Reference Figures 1-2 This embodiment provides a multi-headed shuttle loom. The shuttle loom 100 is equipped with three warp heads, two of which are fixed heads (the fixed heads of the conventional shuttle loom 100 are divided into a first fixed head 1 and a second fixed head 2. The first fixed head 1 tightens the corresponding yarn and introduces it into the shuttle loom 100 through the first transition roller 4, and the second fixed head 2 tightens the corresponding yarn and introduces it into the shuttle loom 100 through the second transition roller 3). The third is an additional fixed head. The height of the fixed loom head is adjusted via an adjustment mechanism, which includes a disc 21, a base frame 22, a base plate 23, a base platform 24, an auxiliary plate 27, a screw 25, and a handwheel 26. The disc 21 is rotatably mounted on the base frame 22. The base plate 23 is welded to the bottom of the base frame 22, and the auxiliary plate 27 is welded to the side of the base frame 22. The screw 25 is threadedly connected to the auxiliary plate 27 and the base plate 23 in sequence. The handwheel 26 is welded to the top of the screw 25. A second roller shaft 20 is provided on the loom 100. The base plate 23 slides vertically within the base platform 24 for adjustment. By rotating the handwheel 26, the screw 25 engages with the threaded connection of the base plate 23, changing the relative position of the base plate 23.

[0046] The disc 21 is a structure that limits the overall side end of the warp beam. The disc 21 and the corresponding yarn are slowly fed out through the control shaft 91. A large gear 90 is installed on the side end of the control shaft 91, and a small gear 93 is installed on the side end of the control motor 92. The small gear 93 meshes with the large gear 90. The small gear 93 facilitates low-speed control of the corresponding warp beam to pull and output the yarn.

[0047] Example 2

[0048] Reference Figures 3-5 This embodiment provides a multi-headed loom. The loom 100 is equipped with three warp heads, two of which are fixed heads (the fixed heads of a traditional loom 100 are divided into a first fixed head 1 and a second fixed head 2. The first fixed head 1 tightens the corresponding yarn and introduces it into the loom 100 through a first transition roller 4, and the second fixed head 2 tightens the corresponding yarn and introduces it into the loom 100 through a second transition roller 3). One is a movable head. Different warp heads warp yarns of the same or different materials in batches, and are then pulled to the warp threading position by the loom 100 to form a woven fabric.

[0049] The movable warp head includes a movable frame 5, movable wheels 7, a warp beam 6, and a first roller 8. Movable wheels 7 are mounted on the bottom of the movable frame 5. The warp beam 6 is mounted on the movable frame 5, and a rotating shaft 10 is provided at its edge. The rotating shaft 10 is constrained on the movable frame 5 by bearings 11. The yarn on the warp beam 6 is drawn to the loom 100 via the first roller 8. The movable frame 5 has slots 51, and several connecting ports 52 are provided within the slots 51. Different warp heads at the front of the loom 100 draw and output yarns. When drawn to the warp threading position, all yarns are on the same horizontal plane. The height of the drawn yarn can be adjusted by connecting and installing the bearings 11 to different connecting ports 52, thereby adjusting the height of the drawn yarn.

[0051] Reference Figures 6-7 This embodiment provides a multi-head shuttle loom. Based on embodiment 2, this embodiment further provides the following structure to enable adjustment of yarn tension. An adjustment frame 42 is hinged to the lower part of the warp beam 6 on the movable frame 5. A cam 40 is provided on the outer end of the warp beam 6. The cam 40 is connected to the adjustment frame 42 through a tension belt 41. Several counterweights 43 are placed on the adjustment frame 42. Figure 8 This is a simplified diagram of the head section of an existing shuttle loom.

[0052] Example 4

[0053] Reference Figures 8-10 This embodiment provides a method for preparing woven fabric, wherein a multi-head loom is equipped with three warp heads, and the method for preparing woven fabric specifically includes the following steps:

[0054] For warping (warp preparation), the first warp yarn uses TPU320D monofilament, the second warp yarn uses TPEE144D monofilament, and the third warp yarn uses 400D polyarylate multifilament. Depending on the design requirements, different warp yarn materials / thicknesses require different warp beams to ensure normal weaving. That is, the first, second, and third warp yarns can be selected according to the structural requirements of the woven fabric.

[0055] On the upper warp head, the first and second warp yarns are attached to the regular positions on the machine, and the third warp yarn is attached to the additional frame;

[0056] The threads are arranged according to a predetermined sequence; an example of the scheme is shown below:

[0057] Heddle threading: One cycle consists of 21 warp threads (warp 1*1 + warp 2*6 + warp 1*1 + warp 2*6 + warp 3*1 + warp 2*6) * 373 cycles, for a total of 7840 warp threads;

[0058] Threading the reed: Reed size 7 (7 holes per centimeter), seven threads per hole; refer to the threading diagram. Figure 9 ;

[0059] Data preparation: Based on the design requirements of the materials, edit the weaving program in the weaving software and input the weaving program into the machine.

[0060] For weft yarn preparation, the first weft yarn uses TPEE 0.13 monofilament, the second weft yarn uses 300D low-elasticity polyester yarn, and the third weft yarn uses 400D polyaramid multifilament.

[0061] Weaving, reference Figure 10 , Figure 11 The red horizontal yarn is weft yarn 1 (TPEE monofilament), the white horizontal yarn is weft yarn 2 (polyester colored yarn), and the pink horizontal yarn is weft yarn 3 (polyaramid core yarn wrapped with polyester colored yarn).

[0062] Vertical green indicates the first warp, vertical (except for green and blue) indicates the second warp, and vertical blue indicates the third warp.

[0063] Black represents the warp yarn on the surface, and the other colors represent the corresponding weft yarn on the surface (dark black in the diagram represents a single cycle); on a shuttle loom, the warp yarn is fixed to the loom, and the weft yarn is carried by the shuttle through the warp yarn. The loops on the shuttle shuttle shuttle between the corresponding warp yarns, fixing the weft yarn to the warp yarn; → represents the weft yarn direction, and ↓ represents the warp yarn direction;

[0064] like Figure 11As shown, the first shuttle weft yarn interweaves with the first, second, and third warp yarns; the second shuttle weft yarn interweaves with the first, second, and third warp yarns; the second shuttle weft yarn interweaves with the first, second, and third warp yarns; the weave structure is a plain weave, and both the warp and weft yarns are made of three different materials.

[0065] Post-treatment includes washing and setting. The washing temperature is 90 degrees Celsius, the speed is 15 meters per minute, and the time is 3 minutes. The setting temperature is 160 degrees Celsius, the speed is 12 meters per minute, and the time is 3.5 minutes.

[0066] The washing temperature ranges from 80 to 100 degrees Celsius, the speed ranges from 10 to 20 meters per minute, and the time ranges from 2 to 5 minutes. The setting temperature ranges from 140 to 180 degrees Celsius, the speed ranges from 8 to 16 meters per minute, and the time ranges from 2 to 5 minutes. Furthermore, the extreme values ​​of each range can be selected. Taking a washing temperature range of 80 to 100 degrees Celsius as an example, the washing temperature can be 80 degrees Celsius or 100 degrees Celsius, with 90 degrees Celsius being preferred. The selection of other range values ​​can be made with reference to this.

[0067] In terms of the structure of woven fabrics, the following patterns can be further selected, such as: plain weave, twill weave, vertical weave, horizontal weave, striped weave (openwork), checkered pattern, diamond pattern, geometric pattern, gradient, fine lines, large patterns, etc.; by selecting the elasticity of the warp and weft yarns, woven fabrics with micro-elasticity, high elasticity, and four-way elasticity can be formed through structural design; the woven fabrics can have transparent, semi-transparent, and color-woven effects by selecting the colors of the warp and weft yarns; woven fabrics can be selected with openwork one-twist-one, openwork one-twist-two, openwork one-twist-six, etc.
