Description

Woven Fabric Fabric System Based on 3D Forming and Its Weaving Method

technical field

The invention belongs to the technical field of textiles, relates to the production technology for textile fabrics and garments, in particular to a production process for producing woven fabrics by using a movement device to precisely position and extrude filaments according to a certain track. The invention is suitable for the production of chemical fiber fabrics. the

Background technique

At present, there are generally the following problems in the production of woven fabrics and subsequent processing:

⑴The production process of woven fabric is longer

At present, the production process of woven fabrics includes cleaning, carding, drawing, roving, spun yarn, winding, batching, warping, sizing, threading, winding, and finally weaving. The process is lengthy and requires production equipment. There are many, it takes a long time, the production workshop requires a large area, the production cost is high, and due to the above reasons, the factory management is difficult and the production automation is difficult. the

⑵ Serious waste in the process of fabric making

At present, most of the clothing is generally irregular in shape, and the general shape of woven fabrics is generally rectangular. Therefore, there must be some fabrics that cannot be utilized as leftovers and are wasted. the

(3) It is difficult to modify the parameters of the woven fabric during the production process, and the processing is not flexible

During the production process of woven fabrics, the warp density of woven fabrics is determined by the warp stopper, heald eyes and reed, which cannot be modified after the settings are completed before production, while the weft density is determined by weft insertion and beating frequency. In actual production In the process, it is also difficult to modify in production. Therefore, the warp and weft density of the same woven fabric is a fixed value. the

⑷The shape of the finished woven fabric is single

In order to adapt to the relatively complete production process of woven fabrics, the shape of woven fabrics is elongated, and the single shape of the finished product makes the processing of fabrics difficult and wasteful in the garment process, and also increases the workload of post-processing and cutting. the

Contents of the invention

The object of the present invention is to provide a novel woven fabric production method, which is characterized by a high degree of automation and mechatronics. the

The new weaving method using this method includes a new type of knitting needle group for spatial movement and controllable feeding through the use of motors and guide rails, a fabric cleaning platform that can inject and discharge liquid, and a corresponding microcomputer control system. the

It is characterized in that the feeding knitting needle can design the movement and feeding of the feeding knitting needle according to the requirements of the parameters of the woven fabric through the following method to produce the woven fabric. the

In this production mode, the warp and weft extension directions of the woven fabric are defined as the warp direction, the weft direction, and the vertical to the warp direction and the weft direction are defined as layer height lines. the

A marking method for woven fabrics is proposed. The woven fabrics are divided into two layers, and the upper part of the woven fabric at the interweaving point and the lower part of the woven fabric are shown in different drawings. as a basis for later production. the

In the direction of the layer height line, the midpoint is taken, and the woven fabric is divided into two layers, which are called the upper weave and the bottom weave, and the upper (lower) weave is called the upper (lower) weave diagram. the

For woven fabrics, mark the warp as X and the weft as Y, and mark them in order, such as X1, X2, X3, Y1, Y2, Y3, etc. Corresponding to the above marks, mark the corresponding warps and wefts of the upper tissue and the bottom tissue. Then, each warp (latitude) line is divided into two parts, one part is marked on the upper organization chart, and the other part is marked on the bottom layer organization chart. Moreover, the representation shape of each warp (latitude) line in the upper figure is a dotted line represented by multiple line segments, and the warp line and the latitude line should be perpendicular or approximately perpendicular to each other. Mark the line segments on each longitude (latitude) line in a certain order, such as from left to right (from top to bottom), such as X1(1), X1(2), X1(3), X1(4) wait. the

Capture the points formed by the intersecting points (organization points) of latitude and longitude lines to obtain the middle-level organization chart. Mark each point on the middle-level organization chart with a line segment that does not exceed half the distance between two similar organizations, and this line segment should form a 45-degree angle with the line segment at the corresponding position on the lower-level organization chart. the

It is proposed that by using a feeding knitting needle group that can move accurately in space, the lower half of the fabric is generated for the first time by using the three-layer weave map that is secondarily generated according to the target woven fabric weave map in space, corresponding to three times respectively. yarn, the separation material on the yarn interweaving point is produced for the second time, and the yarn of the upper half of the fabric is produced for the third time, and the feeding knitting needle group is moved according to the path specified by the corresponding organization chart each time. At the same time, the knitting needle group Accurately extrude the molten silk specified in the organizational chart according to the organization chart to produce a semi-finished product composed of different silk materials, place it in a cleaning tank that can dissolve one of the silk materials, dissolve one of the silk materials, and obtain the finished product woven fabric. the

The feeding knitting needle moves close to the fabric carrier, and performs spatial movement and feeding according to the requirements of the organization chart. the

Create a wiring diagram based on the organization chart. the

Indicate the line segments in the organization chart with thick lines, mark the left end (upper end) of the line segment in the upper left corner of the organization chart as 1, and connect the two ends of the nearest line segment in the order from left to right and from top to bottom . One section of each line segment can only be connected to the unconnected end of the nearest adjacent line segment, and the newly added line segment is represented by a dotted line. The last unconnected point is marked 2. the

It is stipulated that the feeding needle starts to move from position 1 of the organization chart and ends at position 2. the

First, according to the bottom layer organization chart, the feeding needle A moves according to the trajectory and extrudes the silk material A to form the lower layer of the woven fabric, and then, according to the trajectory of the layer organization diagram in the figure, the feeding knitting needle B moves according to the trajectory and extrudes the silk material B forms the middle layer of the woven fabric, and finally, as shown in the upper layer of the figure, the feeding needle A moves along the trajectory and extrudes the silk material A to form the upper layer of the woven fabric to obtain a semi-finished product. the

The semi-finished product is placed in the tank D, the silk material B is dissolved, and the woven fabric E is obtained. the

This method is suitable for making:

⑴ Unshaped chemical fiber woven fabrics, such as triangles, circles, pentagons, etc., and can directly produce woven fabrics of corresponding shapes according to the fabric requirements of the final garment. the

⑵Single piece of woven fabrics with different weft density and warp density requirements, and directly produce the corresponding woven fabrics. the

This method has the following advantages:

(1) Greatly shorten the production process of woven fabrics, and reduce the original multi-step process to a four-step process in the same machine. Significantly reduce production costs. the

⑵Requires a significant reduction in production equipment

(3) It can automatically produce woven fabrics, reduce the labor intensity of workers, and increase the degree of factory automation. the

⑷ Reduce waste. In the traditional clothing production process, since the cloth is rectangular, it needs to be further cut and shaped, and some fabrics are wasted as leftovers. This production method can design the corresponding organization chart according to the clothing cutting requirements, so that the shape and warp direction of the woven fabric Linear density and weft linear density are adapted to its requirements. Reduce leftovers and make full use of resources. the
