Problems solved by technology

The traditional method takes a long time and is inefficient, and the evaluation results may fluctuate greatly due to personal subjective and operational reasons. In addition, many uncontrollable factors still exist in the process of transferring the sample after the snagging is completed. With the evaluation results
Finally, after finishing the evaluation, it is difficult to intuitively read the relevant information of the fabric surface here again

Embodiment approach 1

[0046] The first embodiment of the present invention provides a fabric snagging analysis device, see figure 1 and figure 2 As shown in the above, it includes a fabric moving mechanism, a hooking mechanism, a camera mechanism, and a processing mechanism communicating with the camera mechanism, wherein: the fabric moving mechanism includes a roller, the fabric is wound on the roller, and the roller can rotate around its own axis and drive the fabric to rotate. The snagging mechanism can snag the fabric and obtain a snagging surface, and the shooting range of the camera mechanism covers at least one edge of the side of the drum. The camera mechanism sends an image signal to the processing mechanism according to the collected image of the snagging surface on the side edge of the drum; the processing mechanism generates a three-dimensional figure of the snagging surface according to the image signal.

[0047] In this embodiment, the hooking mechanism includes a hooking member pro...

Embodiment approach 2

[0055] The second embodiment of the present invention provides a fabric snagging analysis device. The second embodiment is different from the first embodiment. The main difference is that in the first embodiment of the present invention, the snagging member is Spherical, using the free hanging of the hooking part to hook the thread, which belongs to the improvement made on the basis of the traditional hammer type; and in the second embodiment of the present invention, see image 3 As shown, the guide rail is used to guide the contact snagging between the hooking member and the fabric.

[0056] Specifically, in this embodiment, the thread hooking movement assembly includes a mobile power source, a push block connected to the mobile power source in transmission, and a guide rail for guiding the moving direction of the thread hooking member. The thread hooking piece is installed on the head of the push block, and the push block is arranged on the guide rail. The mobile power sour...

Embodiment approach 3

[0059] The third embodiment of the present invention provides a fabric snagging analysis device, the third embodiment is a further improvement of the second embodiment, the main improvement is that in the third embodiment of the present invention, see Figure 4 As shown, the head of the push block is connected with the tail of the push block through an elastic member. When the hooking piece is in contact with the fabric, the head of the push block protrudes from the guide rail.

[0060] During the hooking process, the head of the push block protruding from the guide rail can bounce under the interaction force between the roller and the hooking piece, thereby preventing the hooking needle from forming a line contact with the fabric surface.

[0061] In this embodiment, a pressure sensor may also be provided at the contact position between the push block and the elastic member, so as to quantitatively obtain the reaction force received by the push block when deformation occurs. ...

Abstract

The invention relates to the technical field of fabric testing, and discloses fabric snagging analyzing equipment and a fabric snagging analyzing method. The fabric snagging analyzing method comprises the following steps that a fabric is wound on a roller; the roller rotates around the axis of itself and drives the fabric to rotate; a snagging mechanism snags the fabric, and a snagging surface is formed; a photographing mechanism collects an image, on the side edge of the roller, of the snagging surface and sends an image signal to a processing mechanism; the processing mechanism generates a three-dimensional graph of the snagging surface according to the image signal; characteristic parameters of the fabric are extracted from the three-dimensional graph, and a testing result is obtained. According to the fabric snagging analyzing equipment adopting the fabric snagging analyzing method, not only can a three-dimensional image model of fabric snagging be obtained, but also the advantage of being low in cost is achieved.

Description

technical field [0001] The invention relates to the technical field of fabric testing, in particular to a fabric snagging analysis device and a fabric snagging analysis method. Background technique [0002] In daily life, the fabrics that make up clothing are often subjected to external forces during use. For some chemical fiber filament fabrics or knitted clothing products with loose and sparse organizational structures, when encountering thorn-like objects, the fibers or monofilaments in the fabric are easily pulled out, forming loops or being hooked on the surface of the fabric. broken. It not only forms fabric surface defects, affects the appearance of clothing, but also affects the durability of fabrics. Therefore, in the field of clothing production in recent years, the complaints caused by snagging of high-end knitted garments have been on the rise, and the evaluation of the snagging resistance of fabrics is becoming more and more important. [0003] At present, th...
