Methods for testing the color fastness of textiles and associated instruments

Textile color fastness test methods and related instruments

Textile color fastness refers to the dyed or printed fabric or during processing, the degree of fading under the action of external factors (extrusion, friction, washing, rain, exposure, light, seawater immersion, saliva immersion, water stains, sweat stains, etc.) is an important factor in evaluating fabric quality. If the color fastness of the fabric is good, the textile will not easily fade during post-processing or use, and the color will be as bright as new after long-term use; if the color fastness of the fabric is poor, it will be B. Color fading, easy staining or staining, etc., causing many problems. YG2Textile Testing Instruments, Testing Equipment Manufacturer

Textile color fastness tests generally include the following aspects:YG2Textile Testing Instruments, Testing Equipment Manufacturer

1、Nairi color fastness test YG2Textile Testing Instruments, Testing Equipment Manufacturer

When the outerwear is worn, the dye is exposed to sunlight, the end result is that the color of the pieces that are exposed to more sunlight becomes lighter or discolored (usually the back and shoulders), while the color of those parts that are not or less exposed to sunlight remains the same or changes slightly, resulting in the color of the Whole clothing varies, and the style and color are ugly.If the clothing color fastness to light is good, the above problems will not occur, or the effect is svery low and can be ignored. Evaluation of fabric color fastness to sunlight is a very important point in evaluating fabric color fastness. YG2Textile Testing Instruments, Testing Equipment Manufacturer

2, wash fastness test YG2Textile Testing Instruments, Testing Equipment Manufacturer

The color fastness to laundering test is intended to assess the degree of fading of outerwear after soaping and laundering and is also an important item in evaluating the performance of fabric color fastness. Garments with good color fastness to washing, after repeated soaping and washing with waterr the color is stable and does not fade, or the effect is negligible; but some garments have poor color fastness to washing, and fading is obvious after washing and soaping. Especially advanced silk, wool and pure cotton garments are most prone to fading problems. YG2Textile Testing Instruments, Testing Equipment Manufacturer

3, rubbing color fastness testYG2Textile Testing Instruments, Testing Equipment Manufacturer

Color fastness to rubbingThe test is used to evaluate the degree of fading of textiles after they have been subjected to external rubbing during use ahave been exposed to and it is also an important point in evaluating the color fastness performance of textiles. Different parts of clothing are subject to different amounts of friction, so the degree of color fading is also slightly different, for example, the cuffs, elbows, collar and armpits of the jacket and the hips and knees of the pants are most likely to fade due to friction.

4, perspiration fastness testYG2Textile Testing Instruments, Testing Equipment Manufacturer

The color fastness test to perspirationis an important part of evaluating the degree of fading of fabrics after soaking in sweat and evaluating the performance of fabric color fastness. Although the clothing is impregnated with perspiration, whether the dye is solid or not depends on the customer's experience, so special testing is required.YG2Textile Testing Instruments, Testing Equipment Manufacturer

5, Iron-On Dyefastness TestYG2Textile Testing Instruments, Testing Equipment Manufacturer

The Iron-On Sublimation Colorfastness Test is designed to measure the degree of fading of outerwear under high temperature conditionsns to evaluate, and it is also the color fastness of textiles An important point in performance evaluation Clothes with good color fastness to ironing and sublimation, after ironing with electric iron and processing with hot roller, the color is stable and does not fade, or the effect is negligible. Some garments are obviously fading, so this article is also part of the color fastness test.
