Instrument for detecting density of numeral textile fabric

Abstract

The invention discloses a digital fabrics density detector, including a host machine equipped with bracket in the front, a fabrics enlarge component, a CCD photoelectric coupled device, an image conversion circuit as well as a display apparatus, the fabrics enlarge component includes a fabrics measuring device, an optical system with magnifying lens and a camera lens, a a transversal transmission mechanism as well as a focusing mechanism; the CCD photoelectric coupled device is equipped on the top of the camera lens; the image conversion circuit is equipped in the host machine, which includes a analog-to-digital conversion chip; the display apparatus is a LCD with a vertical reticle in the middle, the fabrics image and the straight ruler scale division image captured by the CCD photoelectric coupled device are displayed on the display screen after conversion by the image conversion circuit. Many people can observe and analyze at the same time, for avoiding fabrics density observation differences; the LCD can be arbitrarily regulated within horizontal and vertical range, for guarantying the tester to observe with the most comfortable gesture.

Description

technical field [0001] The invention relates to a fabric density detector, in particular to a digital fabric density detector. 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 art is shown in figure 1 , its main stru...

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.
