Embodiment Construction

[0075] The principles and preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0076] Such as Figure 1-3 As shown, the test device for the one-way drape performance of the fabric in this embodiment includes a box body 2, and the box body 2 is in the shape of a cuboid. The definition of this embodiment: the length direction along the box body is horizontal, the width direction is vertical, and the height direction is vertical . A light source 1 and an air flow sensor 12 are installed on the top inner wall of the box body 2 , and a (whole) uniform light plate 6 is installed on the bottom of the box body 2 .

[0077] Several controllable fans 3 are installed on an inner wall of the box body 2, and a longitudinal guide bar 11 is respectively installed on the upper part of the two side walls adjacent to the inner wall. The cross section of the longitudinal guide bar 11 is concave, and its outer sliding f...

Abstract

The invention discloses a device and a method for testing fabric one-way drape performance. The device for testing the fabric one-way drape performance comprises a box body, the box body is a cube in shape, a light source is installed on the inner wall of the top of the box body, a controllable fan is installed on one inner wall of the box body, two longitudinal conducting rods are respectively installed on two side walls which are adjacent with the inner wall, the longitudinal conducting rod is matched with a longitudinal swing support in a sliding mode, the upper portions of longitudinal swing blocks on two sides are respectively connected with a top image capturing device fixing support, the lower portion of one longitudinal swing support is connected with a lateral image capturing device fixing support, guiding rails is connected between the longitudinal swing blocks on the two sides, the guiding rails are matched with fabric fixing rods in a sliding mode, the fabric fixing rods are used for hanging a fabric sample to be tested, and the top image capturing device fixing support and the lateral image capturing device fixing support are respectively fixed with one or a plurality of image capturing devices. The device for testing the fabric one-way drape performance has the technical effects of strong index pertinence and various evaluating angles, and the testing method is close to real stress features of the fabric and the like.

Description

technical field [0001] The invention belongs to the technical field of textile testing, in particular to a testing device and method for fabric one-way drape performance. Background technique [0002] Drapability is a reflection of the drape degree and drape shape of the fabric. It refers to the ability of the fabric to sag naturally to form a curved surface under the action of its own weight, which has an important impact on the visual beauty of the fabric. Therefore, the evaluation of fabric drapability is a very important part of fabric style. [0003] The traditional fabric drape test method is the umbrella method. Its basic principle is to place a certain area of ​​fabric on a disc, and obtain the drape projection image of the fabric under the illumination of a light source, and calculate the ratio of the projected area to the area of ​​the disc. Determine the drape coefficient. This test method is simple to operate and can well reflect the three-dimensional drape sta...
