Description

Technical Field

[0001] The present invention belongs to the field of fabric performance testing, and relates to a fabric draping device with continuously variable support diameter and a collection method therefor. Background Art

[0002] The draping performance of a fabric is one of the effective manifestations of the mechanical properties and structural parameters of the fabric. Studying the draping performance of a fabric can provide a reference for fabric design and clothing design. In the study of fabric draping performance, the collection and characterization of fabric draping performance are the most important initial steps. In traditional fabric draping performance collection devices, in order to be able to distinguish the draping performance of different fabrics, fabric specimens are often cut into circles with uniform sizes, and then naturally draped onto circular support disks with fixed sizes, and the experimental results in this case are used as the draping performance of the fabric for subsequent analysis.

[0003] However, the draping performance of a fabric is a composite function of multiple fabric parameters such as the warp and weft bending performance, shear performance, and self-weight of the fabric. Using a fabric with a single size in combination with a support disk with a single size cannot fully display the draping performance of the fabric. When the size of the circular fabric is fixed, if the size of the support disk is too small, the protruding length of the fabric sample is relatively large, and all fabric specimens can exhibit a relatively large draping effect with deformation. At this time, the shear performance of the fabric plays a great role in the beauty of the draped fabric. Summary of the Invention

[0004] Aiming at the deficiencies existing in the current situation and in order to more comprehensively display the draping performance of circular fabric specimens, the present invention proposes a fabric draping device with continuously variable support diameter and a collection method therefor.

[0005] On the one hand, the fabric draping device with continuously variable support diameter includes: a circular fabric specimen, a rotating arm, a fixed shaft, a rotating disk, a rotating motor, and an elastic auxiliary support rubber roller.

[0006] The elastic auxiliary rubber roller is wrapped around the outside of the rotating arm in an embedded manner, and the two form an equivalent support disk for supporting the circular fabric specimen.

[0007] The fixed shaft is connected to the rotating arm, the rotating motor is connected to the rotating disk, the rotating motor is used to drive the rotating disk to rotate, and the rotating disk is used to drive the rotating arm to rotate around the fixed shaft.

[0008] On the other hand, the present invention also provides a collection method applied to the fabric draping device with continuously variable support diameter as described above, including the following steps:

[0009] First step: After the circular fabric specimen is naturally draped onto the device, cover the fixed disk on the surface of the circular fabric specimen and make the center of the circular fabric specimen coincide with the center of the fixed disk;

[0010] Step 2: The rotating motor drives the rotating disk to rotate, and the rotating disk drives the rotating arms to rotate around their respective fixed axes.

[0011] Step 3: When the rotating arms rotate around their respective fixed axes, the elastic auxiliary support rubber rollers embedded outside the rotating arms deform under the elastic restoring force, and the diameter of the equivalent support disk becomes smaller.

[0012] Step 4: When the circular fabric specimen rotates naturally supported by the equivalent support disks with different diameters, the image acquisition unit acquires the fabric drape images.

[0013] The beneficial effects of the present invention are as follows: The present invention can acquire the drape results of the same circular fabric specimen on support disks with different diameters in a single sample loading experiment, and more comprehensively display and acquire the drape results of the circular fabric specimen.

[0017] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0018] The following further describes the implementation steps of the present invention with reference to the drawings and specific examples:

[0019] As Figure 1 and Figure 2 shown, the embodiment of the present application provides a fabric drape device with continuously changing support diameter, and uses this device with continuously changing support diameter to acquire the comprehensive drape performance of the fabric specimen. The device includes: circular fabric specimen 1, fixed disk 2, rotating arm 3, fixed axis 4, rotating disk 5, rotating motor 6, elastic auxiliary support rubber roller 7, and image acquisition unit 8.

[0020] As Figure 1 shown, after the circular fabric specimen 1 naturally drapes onto the acquisition device, the fixed disk 2 is covered on the surface of the circular fabric specimen 1 to ensure that the centers of the circular fabric specimen 1 and the fixed disk 2 coincide. At this time, the diameter of the equivalent support disk of the acquisition device is the largest.

[0021] Further, the diameter of the circular fabric specimen is 240 mm, and the diameter of the equivalent support disk varies in the range of 60 - 200 mm.

[0022] Further, the device includes 12 rotating arms 3 and 12 fixed shafts 4. An elastic auxiliary rubber roller 7 is wrapped around the 12 rotating arms 3 in an embedded manner. The 12 rotating arms 3 and the elastic auxiliary rubber roller form an equivalent support disk to support the circular fabric specimen 1. The fixed shaft 4 is connected to the rotating arm 3, and the rotating motor 6 is connected to the rotating disk 5. The rotating motor 6 is used to drive the rotating disk 5 to rotate, and the rotating disk 5 is used to drive the rotating arm 3 to rotate around the fixed shaft 4.

[0023] As Figure 2 shown, when the 12 rotating arms 3 rotate around the 12 fixed shafts 4 respectively in the direction shown by the arrows, the diameter of the equivalent support disk formed by the 12 rotating arms 3 and the elastic auxiliary rubber roller becomes smaller. At this time, the circular fabric specimen 1 can form a new draping result. Therefore, the change in the diameter of the equivalent support disk formed by the 12 rotating arms 3 and the elastic auxiliary support rubber roller 7 can directly change the size ratio between the circular fabric specimen 1 and the equivalent support disk, and directly change the draping result of the circular fabric specimen 1.

[0024] The image acquisition unit 8 acquires fabric draping images under different equivalent support disks. The results are as Figure 3 shown. When the size of the circular fabric specimen 1 is fixed and the diameter of the equivalent support disk changes, the draping result of the circular fabric specimen 1 changes accordingly. This series of images is used as the draping characteristics of the fabric sample 1 for the analysis of fabric draping performance.

[0025] In particular, the equivalent support disk and the fixed disk 2 act together to support and fix the circular fabric to form a natural draping state. The equivalent support disk is not a real disk. It is a polygon object similar to a disk formed by the common support of multiple rotating arms 3 and the externally embedded elastic support auxiliary rubber roller 7. While supporting the natural draping of the circular fabric specimen 1, the equivalent support disk can also change its diameter, thereby more comprehensively demonstrating the draping characteristics of the circular fabric specimen 1.

[0026] The embodiment of the present application also provides an acquisition method applied to the fabric draping device with continuously changing support diameter as described above, including the following steps:

[0027] First step: After the circular fabric specimen 1 naturally drapes onto the device, cover the fixed disk 2 on the surface of the circular fabric specimen 1 to ensure that the centers of the circular fabric specimen 1 and the fixed disk 2 coincide. At this time, the diameter of the equivalent support disk is the largest.

[0028] Step 2: The rotating motor 6 drives the rotating disk 5 to rotate, and the rotating disk 5 drives the 12 rotating arms 3 to rotate around their respective fixed axes 4 respectively.

[0029] Step 3: When the 12 rotating arms 3 rotate around their respective fixed axes 4 respectively, the elastic auxiliary support rubber rollers 7 embedded outside the 12 rotating arms are deformed under the elastic restoring force, and the diameter of the equivalent support disk becomes smaller.

[0030] Step 4: When the circular fabric specimen 1 rotates naturally supported by the equivalent support disks with different diameters, the image acquisition unit 8 acquires the top-down view image of the fabric drape.

[0031] Step 5: The image sequences of the draping results of the circular fabric specimen 1 collected when the equivalent support disks have different diameters are used as the draping characteristics of the specimen for the analysis of the fabric draping performance.

[0032] Although the technical solutions of the present invention have been described in detail and enumerated, it should be understood that for those skilled in the art, making modifications to the above embodiments or adopting equivalent alternative solutions are obvious to those skilled in the art. These modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
