Description

Technical Field

[0001] The invention relates to the field of fiber fabric color fastness detection, and in particular to an integrated textile color fastness synchronous detection device. Background Art

[0002] Color fastness refers to the color fastness of an item, which refers to the degree of fading of dyed fabrics under the influence of external factors during use or processing. The quality of color fastness of textiles will directly affect human safety. Products with poor color fastness will cause the pigment on the fabric to fall off and fade when exposed to sweat, rain or friction during daily wear, causing harmful substances in the dye to adhere to the skin and penetrate into the skin. At the same time, the fading color can easily contaminate other clothes or items.

[0003] The invention patent application with publication number CN114486724A discloses a color fastness detection device for fiber textile fabrics. The above patent clamps the detection fabric by two detection rollers, and performs friction detection on both sides of the fabric at the same time, thereby improving the detection efficiency. At the same time, fabrics of different lengths can be detected by moving the clamping frame. At the same time, the fabric can be kept in a taut state at all times through the spring rod, so that the detection roller and the fabric fit closely, thereby ensuring the accuracy of the detection result.

[0004] However, the above patent can only detect the friction color fastness of textile fabrics, and cannot determine the color fastness of textile fabrics in other situations. At the same time, the detection roller performs friction detection on the entire piece of fabric, which is not convenient for comparing the color difference of the fabric before and after friction.

[0005] Based on this, the present invention provides an integrated textile color fastness synchronous detection device. Summary of the invention

When the push plate 109 rises, a negative pressure is formed between the push plate 109 and the liquid blocking plate 110, and the liquid in the liquid storage tank 101 is extracted. When the push plate 109 descends, the one-way valve 108 is used to block the liquid from flowing back, and the pressure of the liquid between the push plate 109 and the liquid blocking plate 110 pushes the liquid blocking plate 110 to flip downward.Sprinkle the test liquid on the test fabric to test it.
