Description

Technical Field

[0001] The present invention relates to the technical field of the weaving of Zhuanghua Luo products, in particular to a weaving device and a weaving method for knitting Zhuanghua Luo. Background Art

[0002] Luo fabric is also called four - warp twill Luo or chain - type Luo fabric. The warp threads are twisted throughout without fixed twist groups. When weaving, the reed cannot be used to beat the weft. Only a beating - up knife or a needle - comb - like device can be used to push the weft thread towards the fell of the cloth. If the pattern - weaving and inter - lacing technique of Zhuanghua is added to the Luo ground tissue to form Zhuanghua Luo fabric, its weaving difficulty is even greater, the operation process is more complex, and the production efficiency is extremely low.

[0003] Since the Song Dynasty, the output of Zhuanghua Luo fabric has decreased, and it has almost disappeared during the Qing Dynasty. Now it is impossible to weave. Incredibly, the history of Luo fabric with very high weaving difficulty is very long. Han Dynasty Luo or figured Luo has become one of the popular varieties. Generally speaking, the warp and weft density of Zhuanghua Luo is higher than that of gauze varieties, especially the warp density is much higher than that of gauze, and sometimes it is basically the same as that of satin varieties. Coupled with the relatively thick weft thread used, so Zhuanghua Luo belongs to medium - thick silk fabrics. Generally speaking, Zhuanghua fabrics (including Zhuanghua Luo) are woven by large - flower - loom. The large - flower - loom is divided into two parts, upstairs and downstairs, and two workers are required to cooperate up and down. When weaving, the worker upstairs drives the warp thread to lift according to the pattern program of the pattern book, and the worker downstairs weaves the weft thread according to the shed formed by the lifting of the warp thread. The whole process is very complex and the efficiency is low. Summary of the Invention

[0004] The present invention provides a weaving device and a weaving method for knitting Zhuanghua Luo, which improve the weaving efficiency of Zhuanghua Luo products and the quality of the products themselves.

[0005] In order to achieve the object of the present invention, the technical solution adopted is: a weaving device for knitting Zhuanghua Luo, including a weft - inserting part, a warp - feeding part, a take - up part, a beating - up part, a harness and a harness - shed opening part. The harness - shed opening part includes a first barrier, a second barrier, a template and a half - harness for twisting. The half - harness for twisting includes a left half - harness for twisting and a right half - harness for twisting, and both the left half - harness for twisting and the right half - harness for twisting are located in front of the reed.

[0006] As an optimized scheme of the present invention, both the left half - harness for twisting and the right half - harness for twisting include a chute, a half - harness rod, a tension spring, a connecting rope and a first foot rod. The half - harness rod is perpendicular to the chute, and the half - harness rod slides up and down in the chute. Both ends of the half - harness rod are connected to the end of the chute through tension springs. Both ends of the connecting rope are fixed on the half - harness rod, and the middle end of the connecting rope is connected to one end of the first foot rod, and the other end of the first foot rod is fixedly hinged.

[0007] As an optimized scheme of the present invention, one end of the connecting rope is fixed at the 1 / 4 position of the half - harness rod, and the other end of the connecting rope is fixed at the 3 / 4 position of the half - harness rod.

[0008] As an optimized solution of the present invention, the first shoji, the second shoji, the frame, and the twisted half - warp material are made of wire.

[0009] As an optimized solution of the present invention, both ends of the upper frames of the first shoji and the second shoji are suspended on fixed springs, and both ends of the lower frames of the first shoji and the second shoji are connected to one end of the second foot rod by a connecting line, and the other end of the second foot rod is fixed in a hinge - type manner.

[0010] As an optimized solution of the present invention, both ends of the upper frame of the frame are connected to one end of the old duck wing, the other end of the old duck wing is connected to one end of the horizontal edge bamboo by a connecting line, the other end of the horizontal edge bamboo is fixed in a hinge - type manner, the middle section of the horizontal edge bamboo is connected to one end of the third foot rod, and the other end of the third foot rod is fixed in a hinge - type manner.

[0011] To achieve the purpose of the present invention, a method for weaving brocaded luo using a weaving device for brocaded luo includes the following steps:

[0012] 1) First, conduct pattern design. Draw a jacquard draft according to the designed pattern and the set warp and weft densities, and then pick out the pattern wefts according to the jacquard draft to form a jacquard dobby.

[0013] 2) Unwind the warp of the warp beam to the weaving beam.

[0014] 3) The weft direction is composed of three kinds of wefts. The first weft is a single plain weft, which is woven in each time after lifting the frame. The second weft is a brocade pattern weft, which is woven in the state where the threads are lifted and the first shoji or the second shoji is pressed down. The third weft is a left - twisted weft or a right - twisted weft, and the weft is woven by pressing down the left - twisted half - warp or the right - twisted half - warp.

[0015] 4) According to the weft arrangement order of one cycle for every even - numbered shuttle, use the reverse weaving method on the loom. According to the weave diagram of the brocaded luo, one weave cycle is composed of 8 shuttles in the weft direction and 4 warps in the warp direction.

[0016] As an optimized solution of the present invention, the warp span of the left - twisted half - warp and the right - twisted half - warp is two warps.

[0017] As an optimized solution of the present invention, the second weft is woven using the brocade weaving or plain weaving method.

[0018] The present invention has positive effects: 1) The present invention designs the frame and the shoji on the existing large - flower - loom, and adds a left - twisted half - warp and a right - twisted half - warp in front of the reed. After weft insertion, the reed can be used for beating the weft, improving the product quality and weaving efficiency of the brocaded luo.

[0019] 2) The present invention uses 8 shuttles in the weft direction and 4 warps in the warp direction to form one weave cycle, and only 8 foot rods need to be stepped on in sequence to complete various shedding operations, improving the technology and equipment of the brocaded luo, which is beneficial to the replication of the traditional variety of brocaded luo in Yunjin, as well as the protection, display, and production of traditional silk culture.
