Description

Technical Field

[0001] The utility model belongs to the technical field of fabric detection, and more specifically relates to a color fastness detection device for printed and dyed fabrics. Background Art

[0002] It is necessary to detect the fastness of the dyed fabric, that is, the color fastness detection. The common detection method is to simulate the situations that occur in daily life through equipment, such as friction, extrusion, soaking in stains and sweat, rubbing in laundry detergent, and sun exposure, etc., to detect the color fastness of the fabric.

[0003] Generally, only one side of the fabric is printed with patterns or patterns. Therefore, when detecting the rubbing color fastness of the fabric, only the side printed with patterns needs to be rubbed and detected, and the other side does not need to be detected. However, when both sides of the fabric are printed with patterns or patterns, both sides of the fabric need to be detected. When detecting both sides, generally, one side is first rubbed and detected, and then the fabric is flipped to detect the other side, with low efficiency.

[0004] Design a device for synchronously detecting the double-sided rubbing color fastness of printed and dyed fabrics to improve the detection efficiency. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a color fastness detection device for printed and dyed fabrics, which realizes the synchronous detection of the double-sided rubbing color fastness of the sample fabric and improves the detection efficiency.

[0008] Further, a connecting block is arranged on the friction head, a mounting groove corresponding to the connecting block is arranged on the mounting block, a groove is arranged on the connecting block, and a telescopic block corresponding to the groove is arranged in the mounting groove.

[0009] Further, the groove is a V-shaped groove, and the cross section of the telescopic block is V-shaped.

[0010] Further, the clamping device includes a fixed clamping plate and a movable clamping plate. The movable clamping plate is hinged to the fixed clamping plate. A clamping cylinder is arranged on the bracket. A connecting rod is arranged between the clamping cylinder and the movable clamping plate. The two ends of the connecting rod are respectively hinged to the movable clamping plate and the piston rod of the clamping cylinder.

[0011] Further, a white friction cloth is coated on the end face of the friction head. Fixing bolts are arranged on both sides of the friction head. The fixing bolts are in threaded connection with the friction head. Both sides of the friction cloth are fixed by the fixing bolts.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: First, the two sides of the cloth sample to be tested are clamped by the clamping devices on both sides, and white friction cloths are installed on the upper and lower friction heads. Then, the upper and lower friction heads move and contact the sample cloth, and the two friction heads are pressed against the upper and lower sides of the sample fabric.
