Abstract
Description
Technical Field
[0001] The utility model relates to a textile testing device, in particular to a color fastness friction instrument. Background Art
[0002] Color fastness refers to the resistance of the color of textiles to various effects during processing and use. The fastness grade is assessed based on the color change of the test sample and the staining of the undyed adjacent fabric.
[0003] The color fastness test of textiles is a routine test item in the intrinsic quality test of textiles. The principle is to rub the textile sample with a dry friction cloth and a wet friction cloth respectively, so as to evaluate the degree of color staining of the friction cloth.
[0004] During testing, the pressure roller needs to be rotated to press the sample cloth underneath to prevent the sample cloth from moving when rubbed. However, when the pressure roller presses the sample cloth, it is not fixed or restricted. The pressure roller is relatively loose, which may cause the pressure roller to rotate and affect the restriction of the cloth. Utility Model Content

[0008] By adopting the above technical scheme, the two pressure rollers are rotated in different directions to keep them away from the friction table. The rotating pressure rollers make the two movable frames move relative to each other through the rotating rods. Then the sample cloth is placed under the pressure rollers, and the two pressure rollers are rotated back to press the sample cloth. Then the limit bolts are rotated to tighten the movable frame to fix the pressure rollers to prevent the pressure rollers from rotating when the sample cloth is rubbed.
[0009] Preferably, a support plate is fixedly connected to the friction meter near the friction table, and a tightening bolt is threadedly connected to the support plate, and an end of the tightening bolt is in contact with the friction table in the width direction.
[0010] By adopting the above technical solution, after dry rubbing the sample cloth, the friction table and the sample cloth are moved, and wet rubbing is performed on other parts of the sample cloth. The moved friction table is fixed by tightening the fastening bolts to prevent movement during friction.
[0011] Preferably, the head of the tightening bolt is fixedly connected with a rubber head.
[0012] By adopting the above technical solution, the damage to the friction table can be reduced.
[0013] Preferably, the end of the rotating rod is rotatably connected to a roller, and the roller is embedded in a slide groove of the moving frame and is rollingly connected to the moving frame.
