Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] The structure diagram of the system of the present invention is as follows: figure 1 As shown, the fabric is transported by the conveyor belt and moves to the feeding area (a), marking area (b) and visual inspection area (c) respectively for related operations. In the feeding area, the fabric is manually flattened and placed in the middle of the conveyor belt 6; the fabric moves in the marking area, its position is judged by the visual camera lens and the marking mechanism 3 is controlled to perform marking operations; the fabric moves in the visual inspection area to mark points 15 The measurement and related information are recorded by software; the fabric will automatically fall into the fabric finishing box 1 after passing through the visual inspection area, so as to carry out the next operation. After the fabric is washed and dried accord...

Abstract

The invention relates to a method for automatically measuring the dimensional change rate of a fabric. The equipment used includes a detection system, an information processing host and a control platform. The fabric is transported by a conveyor belt to three areas of the feeding area, the marking area and the visual inspection area. Operation, the detection system adopted includes a conveyor belt module, a marking module, a visual camera for marking and a visual detection module, wherein the marking module uses a visual camera to detect whether the fabric enters the marking area completely, so as to whether Marking judgment; the visual inspection module is used to judge whether the fabric has completely entered the visual inspection area, correct the position of the marking point and measure the distance of the marking point.

Description

technical field [0001] The invention belongs to the field of textile quality detection, and relates to an automatic measurement method for fabric size change rate. Background technique [0002] Factors such as fiber composition and fabric structure will affect the dimensional change rate of the fabric before and after washing. During the process of fabric printing, dyeing and use, fibers, yarns and fabrics will be elongated to varying degrees due to tension. After washing, the tension between fibers will be weakened, causing the size of the fabric to change. Therefore, the washing dimensional change rate affects the wearability of the fabric, and is one of the most important items in many textile quality testing items. Industry standards and national standards have assessed and defined the dimensional change rate index of some products after washing. Generally speaking, it is necessary to test the dimensional change of the fabric before and after washing and drying under ce...
