Problems solved by technology

The defect of the fabric density mirror is: it is limited to single observation, and it is not easy for multiple people to compare; if it is used for too long, it will cause dizziness, dizziness and neck pain to the operator
With general processing technology, the width of the engraved line is 0.1-0.15mm. When encountering high-density fabrics with yarn diameters less than 0.1mm, it is difficult to align and determine the actual density of the fabric.
In addition, the image directly observed by the fabric density mirror is an optical image, which cannot be saved or transmitted.

Embodiment 1

[0043] Embodiment 1: Tested by a single machine of a digital fabric density detector. Testing by one tester or by a tester and a retester at the same time. During the test, the test inspector or / and the retest inspector randomly select five test areas on the fabric at the same time, after measuring the value in each test area, take the average value of the value as the final determined value. The test results can be compared and determined by the re-examination inspector after performing the same method test. Pass if the difference is within the allowable range.

[0044] The fabric density image captured by the above stand-alone machine can also be connected to other display media for enlarged display, image storage, print display, and projection display.

Embodiment 2

[0045] Embodiment 2: Test by connecting a computer with a digital fabric density detector

[0046] It is tested by a test inspector, and a test inspector and a re-examination inspector can also be used to test at the same time. The host computer can choose CPU above P2. The operating system uses WINDOW 9X, WINDOW2000, WINDOW XP, etc. The screen resolution is above 800×600. The host computer also needs to be equipped with an AV interface card. During operation, the AV output port on the stand-alone machine of the present invention is connected to the input port of the AV interface card of the host computer. The connecting wire is a commonly used shielded cable. After the host computer is turned on, the AV interface card driver software is executed on the desktop of the operating system. During the test, the test inspector randomly selects five test areas on the fabric, and after measuring the values ​​in each test area, the average value of the values ​​is taken as the fin...

Embodiment 3

[0048] Embodiment three: connect computer and printer by digital fabric density detector. The fabric density image determined and displayed on the computer screen can be printed on a paper carrier by connecting a printer, as a test report document drawing or a test report paper document archive. The printer can choose a color inkjet printer or a color laser printer with a resolution of 600×600, 1200×1200, 1200×2400. The paper carrier can be 80g copy paper, ordinary photo paper, glossy photo paper, high-quality glossy photo paper, matte paper, drawing paper, color machine paper and other glossy photo paper.

Abstract

The invention discloses a digital fabrics density detector and a testing method, the device includes a host machine, a bracket with a perforation on the end face, which is equipped in front of the host machine, a fabrics amplifying component, a CCD photoelectric coupled device, an image conversion circuit as well as a display apparatus, the test method of the tester includes the following steps: first of all, tiling the fabrics on a flattening table-board; then, placing the digital fabrics density detector on fabrics, switching-on a lighting lamp in the optical system towards the fabrics; regulating brightness of lighting lamp and display screen till the fabrics image is clear; then, putting the edge line of the straight ruler parallel to the non-testing system yarns, selecting a scale line of a straight ruler in alignment with the reticle in the middle of the display screen and uses the reticle as the initial point, rotating a transversal transmission mechanism and moving the optical system, counting the number of yarns within prescribed measurement distance; finally, fetching five test regions on the fabrics randomly, repeating the test steps, figuring out the mean value of thread count.

Description

technical field [0001] The invention relates to a fabric density detector and a testing method, in particular to a digital fabric density detector and a testing method. technical background [0002] The number of warp yarns along the horizontal unit length in the fabric is called the warp density, and the number of weft yarns along the longitudinal unit length is called the weft density. The two are collectively referred to as fabric density, which has a great relationship with the weight, wear resistance, hand feel and air permeability of the fabric. Therefore, measuring fabric density and analyzing fabric structure is an important test for assessing fabric quality. According to the national test method standard GB / T 4668-97, the fabric density is the number of yarns measured in a 5 cm wide fabric with a Y511 fabric density microscope, and then converted to the number of yarns per 10 cm in length. [0003] The appearance of the Y511 type fabric density mirror in the prior...
